    Cerebrovascular events in renal transplant recipients2009In: Transplantation, ISSN 0041-1337, E-ISSN 1534-6080, Vol. 87, no 1, p. 112-7Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The incidence of stroke and risk factors for different subtypes of cerebrovascular (CBV) events in renal transplant recipients have not been examined in any large prospective controlled trial. METHODS: The Assessment of Lescol in Renal Transplantation was a randomized, double-blind, placebo-controlled study of the effect of fluvastatin (40-80 mg) daily on cardiovascular, and renal outcomes in renal transplant recipients. Patients initially randomized to fluvastatin or placebo in the 5 to 6 year trial was offered open-label fluvastatin in a 2-year extension to the original study. We investigated the incidence of stroke and risk factors for ischemic and hemorrhagic CBV events in 2102 renal graft recipients participating in the Assessment of Lescol in Renal Transplantation core and extension trial with a mean follow-up of 6.7 years. RESULTS: The incidence and type of CBV events did not differ between the lipid lowering arm and the placebo arm. A total of 184 (8.8%, 95% confidence interval 4.6-12.9) of 2102 patients experienced a CBV event during follow-up, corresponding to an incidence of 1.3% CBV event per year. The mortality for patients experiencing a hemorrhagic stroke was 48% (13 of 27), whereas the mortality for ischemic strokes was 6.0% (8 of 133). Diabetes mellitus, previous CBV event, age, and serum creatinine were independent risk factors for cerebral ischemic events. The risk of a hemorrhagic cerebral event was increased by diabetes mellitus, polycystic kidney disease, left ventricular hypertrophy, and systolic blood pressure. INTERPRETATION: Risk factors for CBV events in renal transplant recipients differ according to subtype.

    Inflammation in renal transplantation2009In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 4, no 7, p. 1246-1254Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND OBJECTIVES: Renal transplant recipients experience premature cardiovascular disease and death. The association of inflammation, all-cause mortality, and cardiovascular events in renal transplant recipients has not been examined in a large prospective controlled trial. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: ALERT was a randomized, double-blind, placebo-controlled study of the effect of fluvastatin on cardiovascular and renal outcomes in 2102 renal transplant recipients. Patients initially randomized to fluvastatin or placebo in the 5- to 6-yr trial were offered open-label fluvastatin in a 2-yr extension to the original study. The association between inflammation markers, high-sensitivity C-reactive protein (hsCRP), and IL-6 on cardiovascular events and all-cause mortality was investigated. RESULTS: The baseline IL-6 value was 2.9 +/- 1.9 pg/ml (n = 1751) and that of hsCRP was 3.8 +/- 6.7 mg/L (n = 1910). After adjustment for baseline values for established risk factors, the hazard ratios for a major cardiac event and all-cause mortality for IL-6 were 1.08 [95% confidence interval (CI), 1.01 to 1.15, P = 0.018] and 1.11 (95% CI, 1.05 to 1.18, P < 0.001), respectively. The adjusted hazard ratio for hsCRP for a cardiovascular event was 1.10 (95% CI, 1.01 to 1.20, P = 0.027) and for all-cause mortality was 1.15 (95% CI, 1.06 to 1.1.25, P = 0.049). CONCLUSIONS: The inflammation markers IL-6 and hsCRP are independently associated with major cardiovascular events and all-cause mortality in renal transplant recipients.

    Asymmetrical dimethylarginine is associated with renal and cardiovascular outcomes and all-cause mortality in renal transplant recipients2010In: Kidney International, ISSN 0085-2538, E-ISSN 1523-1755, Vol. 77, no 1, p. 44-50Article in journal (Refereed)
    Abstract [en]

    Increased plasma levels of asymmetric dimethylarginine (ADMA) are associated with endothelial dysfunction and predict the progression to dialysis and death in patients with chronic kidney disease. The effects of these increased ADMA levels in renal transplant recipients, however, are unknown. We used the data from ALERT, a randomized, double-blind, placebo-controlled study of the effect of fluvastatin on cardiovascular and renal outcomes in 2102 renal transplant recipients with stable graft function on enrollment. Patients who were initially randomized to fluvastatin or placebo in the 5- to 6-year trial were offered open-label fluvastatin in a 2-year extension of the original study. After adjustment for baseline values for established factors in this post hoc analysis, ADMA was found to be a significant risk factor for graft failure or doubling of serum creatinine (hazard ratio 2.78), major cardiac events (hazard ratio 2.61), cerebrovascular events (hazard ratio 6.63), and all-cause mortality (hazard ratio 4.87). In this trial extension, the number of end points increased with increasing quartiles of plasma ADMA levels. All end points were significantly increased in the fourth compared to the first quartile. Our study shows that elevated plasma levels of ADMA are associated with increased morbidity, mortality, and the deterioration of graft function in renal transplant recipients.

    Periprocedural outcome after laparoscopic partial nephrectomy versus radiofrequency ablation for T1 renal tumors:: A modified R.E.N.A.L nephrometry score adjusted comparison.2018In: Acta Radiologica, ISSN 0284-1851, E-ISSN 1600-0455, Vol. 60, no 2, p. 260-268Article in journal (Refereed)
    Abstract [en]

    Background: Comparable oncological outcomes have been seen after surgical nephrectomy and thermal ablation of renal tumors recently. However, periprocedural outcome needs to be assessed for aiding treatment decision.

    Purpose: To compare efficacy rates and periprocedural outcome (technical success, session time, hospitalization time, and complications) after renal tumor treatment with laparoscopic partial nephrectomy (LPN) or radiofrequency ablation (RFA).

    Material and Methods: The initial experience with 49 (treated with LPN) and 84 (treated with RFA) consecutive patients for a single renal tumor (diameter ≤ 5 cm, limited to the kidney) during 2007-2014 was evaluated. Patient and tumor characteristics, efficacy rates, and periprocedural outcome were collected retrospectively. The stratified Mantel Haenzel and Van Elteren tests, adjusted for tumor complexity (with the modified R.E.N.A.L nephrometry score [m-RNS]), were used to assess differences in treatment outcomes.

    Results: Primary efficacy rate was 98% for LPN and 85.7% for RFA; secondary efficacy rate was 93.9% for LPN and 95.2% for RFA; and technical success rate was 87.8% for LPN and 100% for RFA. Median session (m-RNS adjusted P < 0.001; LPN 215 min, RFA 137 min) and median hospitalization time were longer after LPN (m-RNS adjusted P < 0.001; LPN 5 days, RFA 2 days). Side effects were uncommon (LPN 2%, RFA 4.8%). Complications were more frequent after LPN (m-RNS adjusted P < 0.001; LPN 42.9%, RFA 10.7%).

    Conclusion: Both methods achieved equivalent secondary efficacy rates. RFA included several treatment sessions, but session and hospitalization times were shorter, and complications were less frequent than for LPN. The differences remained after adjustment for renal tumor complexity.

    Prostate cancer induces C/EBP expression in surrounding epithelial cells which relates to tumor aggressiveness and patient outcome2019In: The Prostate, ISSN 0270-4137, E-ISSN 1097-0045, Vol. 79, no 5, p. 435-445Article in journal (Refereed)
    Abstract [en]

    Background: Implantation of rat prostate cancer cells into the normal rat prostate results in tumor-stimulating adaptations in the tumor-bearing organ. Similar changes are seen in prostate cancer patients and they are related to outcome. One gene previously found to be upregulated in the non-malignant part of tumor-bearing prostate lobe in rats was the transcription factor CCAAT/enhancer-binding protein- (C/EBP).

    Methods: To explore this further, we examined C/EBP expression by quantitative RT-PCR, immunohistochemistry, and Western blot in normal rat prostate tissue surrounding slow-growing non-metastatic Dunning G, rapidly growing poorly metastatic (AT-1), and rapidly growing highly metastatic (MatLyLu) rat prostate tumors?and also by immunohistochemistry in a tissue microarray (TMA) from prostate cancer patients managed by watchful waiting.

    Results: In rats, C/EBP mRNA expression was upregulated in the surrounding tumor-bearing prostate lobe. In tumors and in the surrounding non-malignant prostate tissue, C/EBP was detected by immunohistochemistry in some epithelial cells and in infiltrating macrophages. The magnitude of glandular epithelial C/EBP expression in the tumor-bearing prostates was associated with tumor size, distance to the tumor, and metastatic capacity. In prostate cancer patients, high expression of C/EBP in glandular epithelial cells in the surrounding tumor-bearing tissue was associated with accumulation of M1 macrophages (iNOS+) and favorable outcome. High expression of C/EBP in tumor epithelial cells was associated with high Gleason score, high tumor cell proliferation, metastases, and poor outcome.

    Conclusions: This study suggest that the expression of C/EBP-beta, a transcription factor mediating multiple biological effects, is differentially expressed both in the benign parts of the tumor-bearing prostate and in prostate tumors, and that alterations in this may be related to patient outcome.

    Bladder biomechanics and the use of scaffolds for regenerative medicine in the urinary bladder2018In: Nature reviews. Urology, ISSN 1759-4812, E-ISSN 1759-4820, Vol. 15, no 3, p. 155-174Article, review/survey (Refereed)
    Abstract [en]

    The urinary bladder is a complex organ with the primary functions of storing urine under low and stable pressure and micturition. Many clinical conditions can cause poor bladder compliance, reduced capacity, and incontinence, requiring bladder augmentation or use of regenerative techniques and scaffolds. To replicate an organ that is under frequent mechanical loading and unloading, special attention towards fulfilling its biomechanical requirements is necessary. Several biological and synthetic scaffolds are available, with various characteristics that qualify them for use in bladder regeneration in vitro and in vivo, including in the treatment of clinical conditions. The biomechanical properties of the native bladder can be investigated using a range of mechanical tests for standardized assessments, as well as mathematical and computational bladder biomechanics. Despite a large body of research into tissue engineering of the bladder wall, some features of the native bladder and the scaffolds used to mimic it need further elucidation. Collection of comparable reference data from different animal models would be a helpful tool for researchers and will enable comparison of different scaffolds in order to optimize characteristics before entering preclinical and clinical trials.

    Mortality Among Men with Locally Advanced Prostate Cancer Managed with Noncurative Intent: A Nationwide Study in PCBaSe Sweden2011In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 60, no 3, p. 554-563Article in journal (Refereed)
    Abstract [en]

    Background

    There are limited prognostic data for locally advanced prostate cancer PCa to guide in the choice of treatment.

    Objective

    To assess mortality in different prognostic categories among men with locally advanced PCa managed with noncurative intent.

    Design, setting, and participants

    We conducted a register-based nationwide cohort study within the Prostate Cancer DataBase Sweden. The entire cohort of locally advanced PCa included 14 908 men. After the exclusion of 2724 (18%) men treated with curative intent, 12 184 men with locally advanced PCa either with local clinical stage T3 or T4 or with T2 with serum levels of prostate-specific antigen (PSA) between 50 and 99 ng/ml and without signs of metastases remained for analysis.

    Measurements

    We followed up the patient cohort in the Cause of Death Register for ≤11 yr and assessed cumulative incidence of PCa -specific death stratified by age and clinical characteristics.

    Results and limitations

    The PCa -specific mortality at 8 yr of follow-up was 28% (95% confidence interval [CI], 25–32%) for Gleason score (GS) 2–6, 41% (95% CI, 38–44%) for GS 7, 52% (95% CI, 47–57%) for GS 8, and 64% (95% CI, 59–69%) for GS 9–10. Even for men aged >85 yr at diagnosis with GS 8–10, PCa was a major cause of death: 42% (95% CI, 37–47%). Men with locally advanced disease and a PSA < 4 ng/ml at diagnosis were at particularly increased risk of dying from PCa. One important limitation is the lack of bone scans in 42% of the patient cohort, but results remained after exclusion of patients with unknown metastasis status.

    Conclusions

    The PCa-specific mortality within 8 yr of diagnosis is high in locally advanced PCa, suggesting undertreatment, particularly among men in older age groups. Our results underscore the need for more studies of treatment with curative intent for locally advanced tumors.

    Initial Experience From Implementation of Hand-Assisted Retroperitoneoscopic Live Donor Nephrectomy in Saudi Arabia2013In: Annals of Saudi Medicine, ISSN 0256-4947, E-ISSN 0975-4466, Vol. 33, no 2, p. S58-S59Article in journal (Refereed)
    Abstract [en]

    Introduction: Donor risks and morbidity are consequences of the invasiveness of donor nephrectomy procedure. The flank incision is currently the default donor nephrectomy procedure at the King Faisal Hospital in Saudi Arabia. In order to minimize the surgical-related trauma, we are implementing the hand-assisted retroperitoneoscopic live donor nephrectomy (HARS), which previously has been shown to promote donor safety. Here, we present our initial experience with this procedure. Material and Methods: The HARS technique was implemented at our center in 2010. We present a survey of our data regarding operative characteristics as well as donor/recipient outcome. Given the small number of cases, data are presented as median with range. Results: Between 2010 and 2013, 18 left -sided HARS nephrectomy procedures were performed. The median donor age and BMI were 26.5 (18-43) and 24.1 (18.7-30.7), respectively. The median hospitalization was 4 days (3-5). One donor presented wound seroma in the pfannenstiell incision with no need for intervention. Another donor presented unspecific thoracoabdominal pain on postoperative day 2. No intra-and postoperative bleeding was observed. The median creatinine at the current follow-up was 90 mu mol/L with 100% graft survival. Conclusion: HARS is a feasible and safe technique. However, for implementation of HARS as the default donor nephrectomy procedure more practice is needed.

    Reduced renal function in patients with Myotonic Dystrophy type 1 and the association to CTG expansion and other potential risk factors for chronic kidney disease2017In: Neuromuscular Disorders, ISSN 0960-8966, E-ISSN 1873-2364, Vol. 27, no 11, p. 1038-1042Article in journal (Refereed)
    Abstract [en]

    Myotonic dystrophy type 1 (DM1) affects several organs. Disease severity and age at onset are correlated to the CTG repeat expansion. The aim of this study was to assess renal function and the association to numbers of CTG repeat expansion in patients with DM1. Ninety-eight patients with DM1 were included. Glomerular filtration rate (measured GFR) was measured using iohexol clearance. Data on CTG repeats were available in 83/98 (85%) patients. The overall mGFR was 74 (16) ml/min/1.73 m(2) (range 38-134). Sixty-four patients (69%) had a mild and sixteen patients (17%) a moderate decrease in renal function (mGFR 60-89 and 30-59 ml/min/1.73 m(2), respectively). No correlations were found between CTG repeats and mGFR (r = 0.10, p = 0.4) or between CTG repeats and serum cystatin C (r = 0.12, p = 0.29). CTG repeats was positively correlated to creatinine-based estimates of GFR (eGFR) (modified diet in renal disease r = 0.49, p < 0.001, CKD-EPI creatinine equation; r = 0.50, p < 0.001), but analyses using Structural Equation Modeling showed no correlation. The correlation was explained by an indirect effect via serum creatinine and skeletal muscle mass index. In conclusion, patients with DM1 seem to have a slight decrease in renal function but there is no association between renal function and the number of CTG repeats, a marker of disease severity.

    FGF-23 and Osteoprotegerin but not Fetuin-A are associated with death and enhance risk prediction in non-dialysis chronic kidney disease stages 3-52016In: Nephrology (Carlton. Print), ISSN 1320-5358, E-ISSN 1440-1797, Vol. 21, no 7, p. 566-573Article in journal (Refereed)
    Abstract [en]

    AIM: Numerous biomarkers have been shown to associate with clinical endpoints in chronic kidney disease (CKD). There is limited evidence whether biomarkers improve risk prediction in relation to clinical outcomes. Our study investigates whether a small suite of key chronic kidney disease-mineral and bone disorder biomarkers could be used to enhance risk assessment in CKD.

    METHODS: Fetuin-A, fibroblast growth factor-23 and osteoprotegerin were measured on baseline plasma samples from 463 patients recruited to the Chronic Renal Insufficiency Standards Implementation Study. The biomarkers were analysed in relation to progression to end stage kidney disease, death and major cardiovascular events.

    RESULTS: Over a median follow up of 46 months (interquartile range 21-69), fibroblast growth factor-23 was associated with risk for renal replacement therapy (hazard ratio (HR) 1.35, P = 0.05, 95% confidence interval (CI) 1.001-1.820), cardiovascular events (HR 1.74 P < 0.001, 95% CI 1.303-1.305) and death (HR 1.4 P = 0.005, 95% CI 1.109-1.767). Osteoprotegerin was associated with risk for death (HR 1.06, P = 0.03, 95% CI 1.006-1.117). There was no clear association between Fetuin-A and any of the clinical endpoints. The addition of biomarkers to risk models led to marginal improvement in model discrimination and reclassification.

    CONCLUSION: Biomarkers are often associated with clinical endpoints, and we observed such associations in our study of patients with advanced CKD. However, the markers analysed in our study were of limited benefit in improving the prediction of these outcomes. Any extra information biomarkers may provide to improve risk prediction in clinical practice needs to be carefully balanced against the potential cost of these tools.

    Changes of arterial pressure following relief of obstruction in adults with hydronephrosis2018In: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 123, no 4, p. 216-224Article in journal (Refereed)
    Abstract [en]

    Background: As much as 20% of all cases of hypertension are associated with kidney malfunctions. We have previously demonstrated in animals and in pediatric patients that hydronephrosis causes hypertension, which was attenuated by surgical relief of the ureteropelvic junction (UPJ) obstruction. This retrospective cohort study aimed to investigate: (1) the proposed link between hydronephrosis, due to UPJ obstruction, and elevated arterial pressure in adults; and (2) if elevated blood pressure in patients with hydronephrosis might be another indication for surgery.

    Materials and methods: Medical records of 212 patients undergoing surgical management of hydronephrosis, due to UPJ obstruction, between 2000 and 2016 were assessed. After excluding patients with confounding conditions and treatments, paired arterial pressures (i.e. before/after surgery) were compared in 49 patients (35 years old; 95% CI 29–39). Split renal function was evaluated by using mercaptoacetyltriglycine (MAG3) renography before surgical management of the hydronephrotic kidney.

    Results: Systolic (−11 mmHg; 95% CI 6–15 mmHg), diastolic (−8 mmHg; 95% CI 4–11 mmHg), and mean arterial (-9 mmHg; 95% CI 6–12) pressures were significantly reduced after relief of the obstruction (p < 0.001). Split renal function of the hydronephrotic kidney was 39% (95% CI 37–41). No correlations were found between MAG3 and blood pressure level before surgery or between MAG3 and the reduction of blood pressure after surgical management of the UPJ obstruction.

    Conclusions: In adults with hydronephrosis, blood pressure was reduced following relief of the obstruction. Our findings suggest that elevated arterial pressure should be taken into account as an indication to surgically correct hydronephrosis.

    Changes in arterial pressure and markers of nitric oxide homeostasis and oxidative stress following surgical correction of hydronephrosis in children2018In: Pediatric nephrology (Berlin, West), ISSN 0931-041X, E-ISSN 1432-198X, Vol. 33, no 4, p. 639-649Article in journal (Refereed)
    Abstract [en]

    Objective Recent clinical studies have suggested an increased risk of elevated arterial pressure in patients with hydronephrosis. Animals with experimentally induced hydronephrosis develop hypertension, which is correlated to the degree of obstruction and increased oxidative stress. In this prospective study we investigated changes in arterial pressure, oxidative stress, and nitric oxide (NO) homeostasis following correction of hydronephrosis.

    Methods Ambulatory arterial pressure (24 h) was monitored in pediatric patients with hydronephrosis (n = 15) before and after surgical correction, and the measurements were compared with arterial pressure measurements in two control groups, i.e. healthy controls (n = 8) and operated controls (n = 8). Markers of oxidative stress and NO homeostasis were analyzed in matched urine and plasma samples.

    Results The preoperative mean arterial pressure was significantly higher in hydronephrotic patients [83 mmHg; 95% confidence interval (CI) 80–88 mmHg] than in healthy controls (74 mmHg; 95% CI 68–80 mmHg; p < 0.05), and surgical correction of ureteral obstruction reduced arterial pressure (76 mmHg; 95% CI 74–79 mmHg; p < 0.05). Markers of oxidative stress (i.e., 11- dehydroTXB2, PGF2α, 8-iso-PGF2α, 8,12-iso-iPF2α-VI) were significantly increased (p < 0.05) in patients with hydronephrosis compared with both control groups, and these were reduced following surgery (p < 0.05). Interestingly, there was a trend for increased NO synthase activity and signaling in hydronephrosis, which may indicate compensatory mechanism(s).

    Conclusion This study demonstrates increased arterial pressure and oxidative stress in children with hydronephrosis compared with healthy controls, which can be restored to normal levels by surgical correction of the obstruction. Once reference data on ambulatory blood pressure in this young age group become available, we hope cut-off values can be defined for deciding whether or not to correct hydronephrosis surgically.

    Surgical treatment reduces blood pressure in children with unilateral congenital hydronephrosis2015In: Journal of Pediatric Urology, ISSN 1477-5131, E-ISSN 1873-4898, Vol. 11, no 2, p. 91.e1-91.e6Article in journal (Refereed)
    Abstract [en]

    Objective Renal disorders can cause hypertension, but less is known about the influence of hydronephrosis on blood pressure. Hydronephrosis due to pelvo-ureteric junction obstruction (PUJO) is a fairly common condition (incidence in newborns of 0.5-1%). Although hypertensive effects of hydronephrosis have been suggested, this has not been substantiated by prospective studies in humans [1-3]. Experimental studies with PUJO have shown that animals with induced hydronephrosis develop salt-sensitive hypertension, which strongly correlate to the degree of obstruction [4-7]. Moreover, relief of the obstruction normalized blood pressure [8]. In this first prospective study our aim was to study the blood pressure pattern in pediatric patients with hydronephrosis before and after surgical correction of the ureteral obstruction. Specifically, we investigated if preoperative blood pressure is reduced after surgery and if split renal function and renographic excretion curves provide any prognostic information. Patients and methods Twelve patients with unilateral congenital hydronephrosis were included in this prospective study. Ambulatory blood pressure (24 h) was measured preoperatively and six months after surgery. Preoperative evaluations of bilateral renal function by Tc99m-MAG3 scintigraphy, and renography curves, classified according to O'Reilly, were also performed. Results As shown in the summary figure, postoperative systolic (103 +/- 2 mmHg) and diastolic (62 +/- 2 mmHg) blood pressure were significantly lower than those obtained preoperatively (110 +/- 4 and 69 +/- 2 mmHg, respectively), whereas no changes in circadian variation or pulse pressure were observed. Renal functional share of the hydronephrotic kidney ranged from 11 to 55%. There was no correlation between the degree of renal function impairment and the preoperative excretory pattern, or between the preoperative excretory pattern and the blood pressure reduction postoperatively. However, preoperative MAG3 function of the affected kidney correlated with the magnitude of blood pressure change after surgery. Discussion Correction of the obstruction lowered blood pressure, and the reduction in blood pressure appeared to correlate with the degree of renal functional impairment, but not with the excretory pattern. Thus, in the setting of hypertension, it appears that the functional share of the hydronephrotic kidney should be considered an indicator of the need for surgery, whereas the renography curve is less reliable. The strength of the present study is the prospective nature and that ambulatory blood pressure monitoring was used. Future longitudinal prolonged follow-up studies are warranted to confirm the present findings, and to understand if a real nephrogenic hypertension with potential necessity of treatment will develop. Conclusion This novel prospective study in patients with congenital hydronephrosis demonstrates a reduction in blood pressure following relief of the obstruction. Based on the present results, we propose that the blood pressure level should also be taken into account when deciding whether to correct hydronephrosis surgically or not.

    Physiological aspects of Toll-like receptor 4 activation in sepsis-induced acute kidney injury2017In: Acta Physiologica, ISSN 1748-1708, E-ISSN 1748-1716, Vol. 219, no 3, p. 575-590Article, review/survey (Refereed)
    Abstract [en]

    Sepsis-induced acute kidney injury (SI-AKI) is common and associated with high mortality. Survivors are at increased risk of chronic kidney disease. The precise mechanism underlying SI-AKI is unknown, and no curative treatment exists. Toll-like receptor 4 (TLR4) activates the innate immune system in response to exogenous microbial products. The result is an inflammatory reaction aimed at clearing a potential infection. However, the consequence may also be organ dysfunction as the immune response can cause collateral damage to host tissue. The purpose of this review is to describe the basis for how ligand binding to TLR4 has the potential to cause renal dysfunction and the mechanisms by which this may take place in gram-negative sepsis. In addition, we highlight areas for future research that can further our knowledge of the pathogenesis of SI-AKI in relation to TLR4 activation. TLR4 is expressed in the kidney. Activation of TLR4 causes cytokine and chemokine release as well as renal leucocyte infiltration. It also results in endothelial and tubular dysfunction in addition to altered renal metabolism and circulation. From a physiological standpoint, inhibiting TLR4 in large animal experimental SI-AKI significantly improves renal function. Thus, current evidence indicates that TLR4 has the ability to mediate SI-AKI by a number of mechanisms. The strong experimental evidence supporting a role of TLR4 in the pathogenesis of SI-AKI in combination with the availability of pharmacological tools to target TLR4 warrants future human studies.

    Reduced expression of ezrin in urothelial bladder cancer signifies more advanced tumours and an impaired survival: validatory study of two independent patient cohorts2014In: BMC Urology, ISSN 1471-2490, E-ISSN 1471-2490, Vol. 14, p. 36-Article in journal (Refereed)
    Abstract [en]

    Background: Reduced membranous expression of the cytoskeleton-associated protein ezrin has previously been demonstrated to correlate with tumour progression and poor prognosis in patients with T1G3 urothelial cell carcinoma of the bladder treated with non-maintenance Bacillus Calmette-Guerin (n = 92), and the associations with adverse clinicopathological factors have been validated in another, unselected, cohort (n = 104). In the present study, we examined the prognostic significance of ezrin expression in urothelial bladder cancer in a total number of 442 tumours from two independent patient cohorts. Methods: Immunohistochemical expression of ezrin was evaluated in tissue microarrays with tumours from one retrospective cohort of bladder cancer (n = 110; cohort I) and one population-based cohort (n = 342; cohort II). Classification regression tree analysis was applied for selection of prognostic cutoff. Kaplan-Meier analysis, log rank test and Cox regression proportional hazards' modeling were used to evaluate the impact of ezrin on 5-year overall survival (OS), disease-specific survival (DSS) and progression-free survival (PFS). Results: Ezrin expression could be evaluated in tumours from 100 and 342 cases, respectively. In both cohorts, reduced membranous ezrin expression was significantly associated with more advanced T-stage (p < 0.001), high grade tumours (p < 0.001), female sex (p = 0.040 and p = 0.013), and membranous expression of podocalyxin-like protein (p < 0.001 and p = 0.009). Moreover, reduced ezrin expression was associated with a significantly reduced 5-year OS in both cohorts (HR = 3.09 95% CI 1.71-5.58 and HR = 2.15(1.51-3.06), and with DSS in cohort II (HR = 2.77, 95% CI 1.78-4.31). This association also remained significant in adjusted analysis in Cohort I (HR1.99, 95% CI 1.05-3.77) but not in Cohort II. In pTa and pT1 tumours in cohort II, there was no significant association between ezrin expression and time to progression. Conclusions: The results from this study validate previous findings of reduced membranous ezrin expression in urothelial bladder cancer being associated with unfavourable clinicopathological characteristics and an impaired survival. The utility of ezrin as a prognostic biomarker in transurethral resection specimens merits further investigation.

    Serum inflammatory markers in relation to prostate cancer severity and death in the Swedish AMORIS study2018In: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 142, no 11, p. 2254-2262Article in journal (Refereed)
    Abstract [en]

    Inflammation is a well-documented driver of cancer development and progression. However, little is known about its role in prostate carcinogenesis. Thus, we examined the association of C-reactive protein (CRP), haptoglobin, albumin and white blood cells (WBC) with prostate cancer (PCa) severity (defined by PCa risk category and clinicopathological characteristics) and progression (defined by PCa death). We selected 8,471 Swedish men with newly diagnosed PCa who had exposure measurements taken approximately 14 years prior to diagnosis. We calculated odds ratio (OR) and 95% confidence interval (CI) for the associations between the inflammatory markers and PCa severity using logistic regression, while Cox proportional hazard regression was used for the associations with overall and PCa death. Serum CRP levels were associated with increased odds of high risk and metastatic PCa, and high PSA levels (20 mu g/L) (OR: 1.29; 95% CI: 1.06-1.56, 1.32; 1.05-1.65 and 1.51; 1.26-1.81, respectively). Similarly, higher haptoglobin levels were associated with increased odds of metastatic PCa, high PSA level and possibly high grade PCa (1.38; 1.10-1.74, 1.50; 1.17-1.93 and 1.25; 1.00-1.56, respectively). Albumin was positively associated with Gleason 4+3 tumour (1.38; 1.02-1.86) and overall death (HRunit increase in log: 1.60; 95% CI: 1.11-2.30), but inversely associated with high risk PCa and high PSA levels (20 mu g/L) (0.71; 0.56-0.89 and 0.72; 0.5 9-0.90). WBC was associated with increased odds of T3-T4 PCa. Except for albumin, none of these markers were associated with PCa death or overall death. Systemic inflammation as early as 14 years prior to diagnosis may influence prostate cancer severity. What's new? High levels of C-reactive protein can presage a particularly malignant prostate cancer, new results show. Cancers certainly arise in the wake of chronic inflammation, but it's not known exactly how markers of inflammation initiate prostate cancer. Here, the authors show that systemic inflammation can worsen the severity of the cancer, even if it occurred long before the cancer's onset. High levels of CRP and haptoglobin, they found, were associated with prostate cancer with high PSA and metastasis. The question remains whether inflammation pushes cancer cells into a more malignant mode, or selects for the more dangerous cells early on.

    Association Between Lead Time and Prostate Cancer Grade: Evidence of Grade Progression from Long-term Follow-up of Large Population-based Cohorts Not Subject to Prostate-specific Antigen Screening2018In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 73, no 6, p. 961-967Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Lead time (LT) is of key importance in early detection of cancer, but cannot be directly measured. We have previously provided LT estimates for prostate cancer (PCa) using archived blood samples from cohorts followed for many years without screening.

    OBJECTIVE: To determine the association between LT and PCa grade at diagnosis to provide an insight into whether grade progresses or is stable over time.

    DESIGN, SETTING, AND PARTICIPANTS: The setting was three long-term epidemiologic studies in Sweden including men not subject to prostate-specific antigen (PSA) screening. The cohort included 1041 men with PSA of 3-10 ng/ml at blood draw and subsequently diagnosed with PCa with grade data available.

    OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable logistic regression was used to predict high-grade (Gleason grade group ≥2 or World Health Organization grade 3) versus low-grade PCa at diagnosis in terms of LT, defined as the time between the date of elevated PSA and the date of PCa diagnosis with adjustment for cohort and age.

    RESULTS AND LIMITATIONS: The probability that PCa would be high grade at diagnosis increased with LT. Among all men combined, the risk of high-grade disease increased with LT (odds ratio 1.13, 95% confidence interval [CI] 1.10-1.16; p<0.0001), with no evidence of differences in effect by age group or cohort. Higher PSA predicted shorter LT by 0.46 yr (95% CI 0.28-0.64; p<0.0001) per 1 ng/ml increase in PSA. However, there was no interaction between PSA and grade, suggesting that the longer LT for high-grade tumors is not simply related to age. Limitations include the assumption that men with elevated PSA and subsequently diagnosed with PCa would have had biopsy-detectable PCa at the time of PSA elevation.

    CONCLUSIONS: Our data support grade progression, whereby following a prostate over time would reveal transitions from benign to low-grade and then high-grade PCa.

    PATIENT SUMMARY: Men with a longer lead time between elevated prostate-specific antigen and subsequent prostate cancer diagnosis were more likely to have high-grade cancers at diagnosis.

    CXCL14 is an autocrine growth factor for fibroblasts and acts as a multi-modal stimulator of prostate tumor growth2009In: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 106, no 9, p. 3414-3419Article in journal (Refereed)
    Abstract [en]

    This study explored the role of secreted fibroblast-derived factors in prostate cancer growth. Analyses of matched normal and tumor tissue revealed up-regulation of CXCL14 in cancer-associated fibroblasts of a majority of prostate cancer. Fibroblasts over-expressing CXCL14 promoted the growth of prostate cancer xenografts, and increased tumor angiogenesis and macrophage infiltration. Mechanistic studies demonstrated that autocrine CXCL14-stimulation of fibroblasts stimulate migration and ERK-dependent proliferation of fibroblasts. CXCL14-stimulation of monocyte migration was also demonstrated. Furthermore, CXCL14-producing fibroblasts, but not recombinant CXCL14, enhanced in vitro proliferation and migration of prostate cancer cells and in vivo angiogenesis. These studies thus identify CXCL14 as a novel autocrine stimulator of fibroblast growth and migration, with multi-modal tumor-stimulatory activities. In more general terms, our findings suggest autocrine stimulation of fibroblasts as a previously unrecognized mechanism for chemokine-mediated stimulation of tumor growth, and suggest a novel mechanism whereby cancer-associated fibroblasts achieve their pro-tumorigenic phenotype.

    The standardization of terminology of lower urinary tract function in children and adolescents: Update report from the standardization committee of the International Children's Continence Society2016In: Neurourology and Urodynamics, ISSN 0733-2467, E-ISSN 1520-6777, Vol. 35, no 4, p. 471-481Article in journal (Refereed)
    Abstract [en]

    AimThe impact of the original International Children's Continence Society (ICCS) terminology document on lower urinary tract (LUT) function resulted in the global establishment of uniformity and clarity in the characterization of LUT function and dysfunction in children across multiple healthcare disciplines. The present document serves as a stand-alone terminology update reflecting refinement and current advancement of knowledge on pediatric LUT function. MethodsA variety of worldwide experts from multiple disciplines within the ICCS leadership who care for children with LUT dysfunction were assembled as part of the standardization committee. A critical review of the previous ICCS terminology document and the current literature was performed. Additionally, contributions and feedback from the multidisciplinary ICCS membership were solicited. ResultsFollowing a review of the literature over the last 7 years, the ICCS experts assembled a new terminology document reflecting current understanding of bladder function and LUT dysfunction in children using the resources from the literature review, expert opinion and ICCS member feedback. ConclusionsThe present ICCS terminology document provides a current and consensus update to the evolving terminology and understanding of LUT function in children.

    Efficacy and safety of more intensive lowering of LDL cholesterol: a meta-analysis of data from 170,000 participants in 26 randomized trials2010In: The Lancet, ISSN 0140-6736, E-ISSN 1474-547X, Vol. 376, no 9753, p. 1670-1681Article in journal (Refereed)
    Abstract [en]

    Background

    Lowering of LDL cholesterol with standard statin regimens reduces the risk of occlusive vascular events in a wide range of individuals. We aimed to assess the safety and efficacy of more intensive lowering of LDL cholesterol with statin therapy.

    Methods

    We undertook meta-analyses of individual participant data from randomised trials involving at least 1000 participants and at least 2 years' treatment duration of more versus less intensive statin regimens (five trials; 39 612 individuals; median follow-up 5·1 years) and of statin versus control (21 trials; 129 526 individuals; median follow-up 4·8 years). For each type of trial, we calculated not only the average risk reduction, but also the average risk reduction per 1·0 mmol/L LDL cholesterol reduction at 1 year after randomisation.

    Findings

    In the trials of more versus less intensive statin therapy, the weighted mean further reduction in LDL cholesterol at 1 year was 0·51 mmol/L. Compared with less intensive regimens, more intensive regimens produced a highly significant 15% (95% CI 11–18; p<0·0001) further reduction in major vascular events, consisting of separately significant reductions in coronary death or non-fatal myocardial infarction of 13% (95% CI 7–19; p<0·0001), in coronary revascularisation of 19% (95% CI 15–24; p<0·0001), and in ischaemic stroke of 16% (95% CI 5–26; p=0·005). Per 1·0 mmol/L reduction in LDL cholesterol, these further reductions in risk were similar to the proportional reductions in the trials of statin versus control. When both types of trial were combined, similar proportional reductions in major vascular events per 1·0 mmol/L LDL cholesterol reduction were found in all types of patient studied (rate ratio [RR] 0·78, 95% CI 0·76–0·80; p<0·0001), including those with LDL cholesterol lower than 2 mmol/L on the less intensive or control regimen. Across all 26 trials, all-cause mortality was reduced by 10% per 1·0 mmol/L LDL reduction (RR 0·90, 95% CI 0·87–0·93; p<0·0001), largely reflecting significant reductions in deaths due to coronary heart disease (RR 0·80, 99% CI 0·74–0·87; p<0·0001) and other cardiac causes (RR 0·89, 99% CI 0·81–0·98; p=0·002), with no significant effect on deaths due to stroke (RR 0·96, 95% CI 0·84–1·09; p=0·5) or other vascular causes (RR 0·98, 99% CI 0·81–1·18; p=0·8). No significant effects were observed on deaths due to cancer or other non-vascular causes (RR 0·97, 95% CI 0·92–1·03; p=0·3) or on cancer incidence (RR 1·00, 95% CI 0·96–1·04; p=0·9), even at low LDL cholesterol concentrations.

    Interpretation

    Further reductions in LDL cholesterol safely produce definite further reductions in the incidence of heart attack, of revascularisation, and of ischaemic stroke, with each 1·0 mmol/L reduction reducing the annual rate of these major vascular events by just over a fifth. There was no evidence of any threshold within the cholesterol range studied, suggesting that reduction of LDL cholesterol by 2–3 mmol/L would reduce risk by about 40–50%.

    Androgen Deprivation Therapies and Changes in Comorbidity: A Comparison of Gonadotropin-releasing Hormone Agonists and Antiandrogen Monotherapy as Primary Therapy in Men with High-risk Prostate Cancer2019In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 75, no 4, p. 676-683Article in journal (Refereed)
    Abstract [en]

    Background: Some studies suggest that gonadotropin-releasing hormone (GnRH) agonists are associated with higher risk of adverse events than antiandrogens (AAs) monotherapy. However, it has been unclear whether this is due to indication bias.

    Objective: To investigate rates of change in comorbidity for men on GnRH agonists versus AA monotherapy in a population-based register study.

    Design, setting, and participants: Men with advanced nonmetastatic prostate cancer (PCa) who received primary AA (n = 2078) or GnRH agonists (n = 4878) and age- and area-matched PCa-free men were selected from Prostate Cancer Database Sweden 3.0. Increases in comorbidity were measured using the Charlson Comorbidity Index (CCI), from 5 yr before through to 5 yr after starting androgen deprivation therapy (ADT).

    Outcome measures and statistical methods: Multivariable linear regression was used to determine differences in excess rate of CCI change before and after ADT initiation. Risk of any incremental change in CCI following ADT was assessed using multivariable Cox regression analyses.

    Results and limitations: Men on GnRH agonists experienced a greater difference in excess rate of CCI change after starting ADT than men on AA monotherapy (5.6% per yr, p < 0.001). Risk of any new CCI change after ADT was greater for GnRH agonists than for AA (hazard ratio, 1.32; 95% confidence interval, 1.20-144).

    Conclusions: Impact on comorbidity was lower for men on AA monotherapy than for men on GnRH agonists. Our results should be confirmed through randomised trials of effectiveness and adverse effects, comparing AA monotherapy and GnRH agonists in men with advanced nonmetastatic PCa who are unsuitable for curative treatment.

    Patient summary: Hormone therapies for advanced prostate cancer can increase the risk of other diseases (eg, heart disease, diabetes). This study compared two common forms of hormone therapy and found that the risk of another serious disease was higher for those on gonadotropin-releasing hormone agonists than for those on antiandrogen monotherapy.

    Satisfaction with Care Among Men with Localised Prostate Cancer: A Nationwide Population-based Study2018In: European Urology Oncology, Vol. 1, no 1, p. 37-45Article in journal (Refereed)
    Abstract [en]

    Abstract

    Background

    Information about how men with prostate cancer (PC) experience their medical care and factors associated with their overall satisfaction with care (OSC) is limited.

    Objective

    To investigate OSC and factors associated with OSC among men with low-risk PC.

    Design, setting, and participants

    Men registered in the National Prostate Cancer Register of Sweden as diagnosed in 2008 with low-risk PC at the age of ≤70 yr who had undergone radical prostatectomy (RP), radiotherapy (RT), or started on active surveillance (AS) were invited in 2015 to participate in this nationwide population-based survey (n = 1720).

    Outcome measurements and statistical analysis

    OSC data were analysed using ordinal logistic regression. Odds ratios (ORs) were calculated for comparisons between the highest and lowest possible response categories.

    Results and limitations

    A total of 1288 men (74.9%) responded. High OSC was reported by 958 (74.4%). Factors associated with high OSC were high participation in decision-making (OR 4.18, 95% confidence interval [CI] 2.61–6.69), receiving more information (OR 11.1, 95% CI 7.97–15.6), high-quality information (OR 7.85, 95% CI 5.46–11.3), access to a nurse navigator (OR 1.80, 95% CI 1.44–2.26), and better functional outcomes (defined as 25 points higher on the EPIC-26 questionnaire; OR 1.34, 95% CI 1.21–1.48). OSC was not affected by whether a doctor or specialist nurse conducted follow-up (OR 0.84, 95% CI 0.66–1.07). These findings were similar across treatment groups. Men who had undergone RP or RT reported high OSC more often than men on AS (78.2% vs 84.0% vs 72.6%), high participation in decision-making (70.5% vs 64.5% vs 49.2%), and having received more information (40.5% vs 45.8% vs 28.6%), and were less likely to believe they would die from PC (3.8% vs 3.9% vs 8.0%). Limitations include the nonrandomised retrospective design and potential recall bias.

    Conclusions

    Information and participation in decision-making, as well as access to a nurse navigator, are key factors for OSC, regardless of treatment. Men on AS need more information about their treatment and need to participate more in decision-making. OSC was as high among men who had nurse-led follow-up as among men who had doctor-led follow-up.

    Patient summary

    Information about how men with low-risk prostate cancer experience their medical care is limited. In this nationwide population-based study we found that information and participation in decision-making as well as access to a nurse navigator are key factors for satisfaction regardless of treatment. Men who are being closely watched for prostate cancer without immediate curative treatment need more information than they now receive and need to participate more in decision-making than they currently do.

    Increased CD4(+) T cell lineage commitment determined by CpG methylation correlates with better prognosis in urinary bladder cancer patients2018In: Clinical Epigenetics, E-ISSN 1868-7083, Vol. 10, article id 102Article in journal (Refereed)
    Abstract [en]

    Background: Urinary bladder cancer is a common malignancy worldwide. Environmental factors and chronic inflammation are correlated with the disease risk. Diagnosis is performed by transurethral resection of the bladder, and patients with muscle invasive disease preferably proceed to radical cystectomy, with or without neoadjuvant chemotherapy. The anti-tumour immune responses, known to be initiated in the tumour and draining lymph nodes, may play a major role in future treatment strategies. Thus, increasing the knowledge of tumour-associated immunological processes is important. Activated CD4(+) T cells differentiate into four main separate lineages: Th1, Th2, Th17 and Treg, and they are recognized by their effector molecules IFN-gamma, IL-13, IL-17A, and the transcription factor Foxp3, respectively. We have previously demonstrated signature CpG sites predictive for lineage commitment of these four major CD4(+ )T cell lineages. Here, we investigate the lineage commitment specifically in tumour, lymph nodes and blood and relate them to the disease stage and response to neoadjuvant chemotherapy.

    Results: Blood, tumour and regional lymph nodes were obtained from patients at time of transurethral resection of the bladder and at radical cystectomy. Tumour-infiltrating CD4(+ )lymphocytes were significantly hypomethylated in all four investigated lineage loci compared to CD4(+) lymphocytes in lymph nodes and blood (lymph nodes vs rumour-infiltrating lymphocytes: IFNG -4229 bp p < 0.0001, IL13 -11 bp p < 0.05, IL17A -122 bp p < 0.01 and FOXP3 -77 bp p> 0.05). Examination of individual lymph nodes displayed different methylation signatures, suggesting possible correlation with future survival. More advanced post-cystectomy tumour stages correlated significantly with increased methylation at the IFNG -4229 bp locus. Patients with complete response to neoadjuvant chemotherapy displayed significant hypomethylation in CD4(+ )T cells for all four investigated loci, most prominently in IFNG p < 0.0001. Neoadjuvant chemotherapy seemed to result in a relocation of Th1-committed CD4(+) T cells from blood, presumably to the tumour, indicated by shifts in the methylation patterns, whereas no such shifts were seen for lineages corresponding to IL13, IL17A and FOXP3.

    Conclusion: Increased lineage commitment in CD4(+) T cells, as determined by demethylation in predictive CpG sites, is associated with lower post-cystectomy tumour stage, complete response to neoadjuvant chemotherapy and overall better outcome, suggesting epigenetic profiling of CD4(+) T cell lineages as a useful readout for clinical staging.

    FGFR3, TERT and OTX1 as a Urinary Biomarker Combination for Surveillance of Patients with Bladder Cancer in a Large Prospective Multicenter Study2017In: Journal of Urology, ISSN 0022-5347, E-ISSN 1527-3792, Vol. 197, no 6, p. 1410-1418Article in journal (Refereed)
    Abstract [en]

    Purpose: Patients with nonmuscle invasive bladder cancer are followed with frequent cystoscopies. In this study FGFR3, TERT and OTX1 were investigated as a diagnostic urinary marker combination during followup of patients with primary nonmuscle invasive bladder cancer.

    Materials and Methods: In this international, multicenter, prospective study 977 patients with nonmuscle invasive bladder cancer were included. A total of 2,496 urine samples were collected prior to cystoscopy during regular visits. Sensitivity was estimated to detect concomitant recurrences. Kaplan-Meier curves were used to estimate the development of future recurrences after urinalysis and a negative cystoscopy.

    Results: Sensitivity of the assay combination for recurrence detection was 57% in patients with primary low grade, nonmuscle invasive bladder cancer. However, sensitivity was 83% for recurrences that were pT1 or muscle invasive bladder cancer. Of the cases 2% progressed to muscle invasive bladder cancer. Sensitivity for recurrence detection in patients with primary high grade disease was 72% and 7% of them had progression to muscle invasive bladder cancer. When no concomitant tumor was found by cystoscopy, positive urine samples were more frequently followed by a recurrence over time compared to a negative urine sample (58% vs 36%, p < 0.001). High stage recurrences were identified within 1 year after a positive urine test and a negative cystoscopy.

    Conclusions: Recurrences in patients with primary nonmuscle invasive bladder cancer can be detected by a combination of urine assays. This study supports the value of urinalysis as an alternative diagnostic tool in patients presenting with low grade tumors and as a means to identify high stage tumors earlier.

    The multifaceted role of complement in kidney transplantation2018In: Nature Reviews Nephrology, ISSN 1759-5061, E-ISSN 1759-507X, Vol. 14, no 12, p. 767-781Article, review/survey (Refereed)
    Abstract [en]

    Increasing evidence indicates an integral role for the complement system in the deleterious inflammatory reactions that occur during critical phases of the transplantation process, such as brain or cardiac death of the donor, surgical trauma, organ preservation and ischaemia-reperfusion injury, as well as in humoral and cellular immune responses to the allograft. Ischaemia is the most common cause of complement activation in kidney transplantation and in combination with reperfusion is a major cause of inflammation and graft damage. Complement also has a prominent role in antibody-mediated rejection (ABMR) owing to ABO and HL A incompatibility, which leads to devastating damage to the transplanted kidney. Emerging drugs and treatment modalities that inhibit complement activation at various stages in the complement cascade are being developed to ameliorate the damage caused by complement activation in transplantation. These promising new therapies have various potential applications at different stages in the process of transplantation, including inhibiting the destructive effects of ischaemia and/or reperfusion injury, treating ABMR, inducing accommodation and modulating the adaptive immune response.

    Radical Prostatectomy or Watchful Waiting in Prostate Cancer: 29-Year Follow-up2018In: New England Journal of Medicine, ISSN 0028-4793, E-ISSN 1533-4406, Vol. 379, no 24, p. 2319-2329Article in journal (Refereed)
    Abstract [en]

    BACKGROUND Radical prostatectomy reduces mortality among men with clinically detected localized prostate cancer, but evidence from randomized trials with long-term followup is sparse.

    METHODS We randomly assigned 695 men with localized prostate cancer to watchful waiting or radical prostatectomy from October 1989 through February 1999 and collected follow-up data through 2017. Cumulative incidence and relative risks with 95% confidence intervals for death from any cause, death from prostate cancer, and metastasis were estimated in intention-to-treat and per-protocol analyses, and numbers of years of life gained were estimated. We evaluated the prognostic value of histopathological measures with a Cox proportional-hazards model.

    RESULTS By December 31, 2017, a total of 261 of the 347 men in the radical-prostatectomy group and 292 of the 348 men in the watchful-waiting group had died; 71 deaths in the radical-prostatectomy group and 110 in the watchful-waiting group were due to prostate cancer (relative risk, 0.55; 95% confidence interval [CI], 0.41 to 0.74; P<0.001; absolute difference in risk, 11.7 percentage points; 95% CI, 5.2 to 18.2). The number needed to treat to avert one death from any cause was 8.4. At 23 years, a mean of 2.9 extra years of life were gained with radical prostatectomy. Among the men who underwent radical prostatectomy, extracapsular extension was associated with a risk of death from prostate cancer that was 5 times as high as that among men without extracapsular extension, and a Gleason score higher than 7 was associated with a risk that was 10 times as high as that with a score of 6 or lower (scores range from 2 to 10, with higher scores indicating more aggressive cancer).

    CONCLUSIONS Men with clinically detected, localized prostate cancer and a long life expectancy benefited from radical prostatectomy, with a mean of 2.9 years of life gained. A high Gleason score and the presence of extracapsular extension in the radical prostatectomy specimens were highly predictive of death from prostate cancer.

    Prediction of clinical progression after radical prostatectomy in a nationwide population-based cohort2016In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 50, no 4, p. 255-259Article in journal (Refereed)
    Abstract [en]

    Objective: The aim of this study was to create a model for predicting progression-free survival after radical prostatectomy for localized prostate cancer. Material and methods: The risk of biochemical recurrence (BCR) was modelled in a cohort of 3452 men aged 70 years or younger who were primarily treated with radical prostatectomy after being diagnosed between 2003 and 2006 with localized prostate cancer [clinical stage T1c-T2, Gleason score 5-10, N0/NX, M0/MX, prostate-specific antigen (PSA)<20 ng/ml]. The cohort was split into two: one cohort for model development (n = 3452) and one for validation (n = 1762). BCR was defined as two increasing PSA values of at least 0.2 ng/ml, initiation of secondary therapy, distant metastases or death from prostate cancer. Multivariable Cox proportional hazard regression was applied, predictive performance was assessed using the bootstrap resampling technique to calculate the c index, and calibration of the model was evaluated by comparing predicted and observed Kaplan-Meier 1 year BCR. Results: The overall 5 year progression-free survival was 83% after a median follow-up time of 6.8 years in the development cohort and 7.3 years in the validation cohort. The final model included T stage, PSA level, primary and secondary Gleason grade, and number of positive and negative biopsies. The c index for discrimination between high and low risk of recurrence was 0.68. The probability of progression-free survival ranged from 22% to 97% over the range of risk scores in the study population. Conclusions: This model is based on nationwide population-based data and can be used with a fair predictive accuracy to guide decisions on clinical follow-up after prostatectomy. An online calculator for convenient clinical use of the model is available at www.npcr.se/nomogram

    Accuracy of GFR estimating equations combining standardized cystatin C and creatinine assays: a cross-sectional study in Sweden2015In: Clinical Chemistry and Laboratory Medicine, ISSN 1434-6621, E-ISSN 1437-4331, Vol. 53, no 3, p. 403-414Article in journal (Refereed)
    Abstract [en]

     Background: The recently established international cystatin C calibrator makes it possible to develop non-laboratory specific glomerular filtration rate (GFR) estimating (eGFR) equations. This study compares the performance of the arithmetic mean of the revised Lund-Malmö creatinine and CAPA cystatin C equations (MEANLM-REV+CAPA), the arithmetic mean of the Chronic Kidney Disease Epidemiology Collaboration equation (CKD-EPI) creatinine and cystatin C equations (MEANCKD-EPI), and the composite CKD-EPI equation (CKD-EPICREA+CYSC) with the corresponding single marker equations using internationally standardized calibrators for both cystatin C and creatinine.

    Methods: The study included 1200 examinations in 1112 adult Swedish patients referred for measurement of GFR (mGFR) 2008-2010 by plasma clearance of iohexol (median 51 mL/min/1.73 m2). Bias, precision (interquartile range, IQR) and accuracy (percentage of estimates ±30% of mGFR; P30) were compared.

    Results: Combined marker equations were unbiased and had higher precision and accuracy than single marker equations. Overall results of MEANLM-REV+CAPA/MEANCKD-EPI/CKD-EPICREA+CYSC were: median bias -2.2%/-0.5%/-1.6%, IQR 9.2/9.2/8.8 mL/min/1.73 m2, and P30 91.3%/91.0%/91.1%. The P30 figures were about 7-14 percentage points higher than the single marker equations. The combined equations also had a more stable performance across mGFR, age and BMI intervals, generally with P30 ≥90% and never <80%. Combined equations reached P30 of 95% when the difference between eGFRCREA and eGFRCYSC was <10% but decreased to 82% at a difference of ≥40%.

    Conclusions: Combining cystatin C and creatinine assays improves GFR estimations with P30 ≥90% in adults. Reporting estimates of both single and combined marker equations in clinical settings makes it possible to assess the validity of the combined equation based on the agreement between the single marker equations.

    Open-label, clinical phase I studies of tasquinimod in patients with castration-resistant prostate cancer2009In: British Journal of Cancer, ISSN 0007-0920, E-ISSN 1532-1827, Vol. 101, no 8, p. 1233-40Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Tasquinimod is a quinoline-3-carboxamide derivative with anti-angiogenic activity. Two open-label phase I clinical trials in patients were conducted to evaluate the safety and tolerability of tasquinimod, with additional pharmacokinetic and efficacy assessments. METHODS: Patients with castration-resistant prostate cancer with no previous chemotherapy were enrolled in this study. The patients received tasquinimod up to 1 year either at fixed doses of 0.5 or 1.0 mg per day or at an initial dose of 0.25 mg per day that escalated to 1.0 mg per day. RESULTS: A total of 32 patients were enrolled; 21 patients were maintained for >or=4 months. The maximum tolerated dose was determined to be 0.5 mg per day; but when using stepwise intra-patient dose escalation, a dose of 1.0 mg per day was well tolerated. The dose-limiting toxicity was sinus tachycardia and asymptomatic elevation in amylase. Common treatment-emergent adverse events included transient laboratory abnormalities, anaemia, nausea, fatigue, myalgia and pain. A serum prostate-specific antigen (PSA) decline of >or=50% was noted in two patients. The median time to PSA progression (>25%) was 19 weeks. Only 3 out of 15 patients (median time on study: 34 weeks) developed new bone lesions. CONCLUSION: Long-term continuous oral administration of tasquinimod seems to be safe, and the overall efficacy results indicate that tasquinimod might delay disease progression.

    Family History and Probability of Prostate Cancer, Differentiated by Risk Category: A Nationwide Population-Based Study2016In: Journal of the National Cancer Institute, ISSN 0027-8874, E-ISSN 1460-2105, Vol. 108, no 10, article id djw110Article in journal (Refereed)
    Abstract [en]

    Background: Familial prostate cancer risk estimates are inflated by clinically insignificant low-risk cancer, diagnosed after prostate-specific antigen testing. We provide age-specific probabilities of non-low-and high-risk prostate cancer. Methods: Fifty-one thousand, eight hundred ninety-seven brothers of 32 807 men with prostate cancer were identified in Prostate Cancer data Base Sweden (PCBaSe). Nelson-Aalen estimates with 95% confidence intervals (CIs) were calculated for cumulative, family history-stratified probabilities of any, non-low-(any of Gleason score >= 7, prostate-specific antigen [PSA] >= 10 ng/mL, T3-4, N1, and/or M1) and high-risk prostate cancer (Gleason score >= 8 and/or T3-4 and/or PSA >= 20 ng/mL and/or N1 and/or M1). Results: The population probability of any prostate cancer was 4.8% (95% CI = 4.8% to 4.9%) at age 65 years and 12.9% (95% CI = 12.8% to 12.9%) at age 75 years, of non-low-risk prostate cancer 2.8% (95% CI = 2.7% to 2.8%) at age 65 years and 8.9% (95% CI = 8.8% to 8.9%) at age 75 years, and of high-risk prostate cancer 1.4% (95% CI = 1.3% to 1.4%) at age 65 years and 5.2% (95% CI = 5.1% to 5.2%) at age 75 years. For men with one affected brother, probabilities of any prostate cancer were 14.9% (95% CI = 14.1% to 15.8%) at age 65 years and 30.3% (95% CI = 29.3% to 31.3%) at age 75 years, of non-low-risk prostate cancer 7.3% (95% CI = 6.7% to 7.9%) at age 65 years and 18.8% (95% CI = 17.9% to 19.6%) at age 75 years, and of high-risk prostate cancer 3.0% (95% CI = 2.6% to 3.4%) at age 65 years and 8.9% (95% CI = 8.2% to 9.5%) at age 75 years. Probabilities were higher for men with a stronger family history. For example, men with two affected brothers had a 13.6% (95% CI = 9.9% to 17.6 %) probability of high-risk cancer at age 75 years. Conclusions: The age-specific probabilities of non-low-and high-risk cancer presented here are more informative than relative risks of any prostate cancer and more suitable to use for counseling men with a family history of prostate cancer.

    Undertreatment of Men in Their Seventies with High-risk Nonmetastatic Prostate Cancer2015In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 68, no 1, p. 53-58Article in journal (Refereed)
    Abstract [en]

    Background: Many elderly men with high-risk nonmetastatic prostate cancer (HRnMPCa) do not receive radical treatment, despite the high mortality associated with conservative management. Objective: To investigate how age and comorbidity affect treatment of men with HRnMPCa. Design, setting, and participants: This was an observational nationwide register study during 2001-2012. We identified 19 190 men of <80 yr of age diagnosed with HRnMPCa in the National Prostate Cancer Register of Sweden and 95 948 age-matched men without prostate cancer in the register of the total population. Outcome measurements and statistical analysis: The outcome was the proportion of men with HRnMPCa receiving radical treatment (radical prostatectomy or radiotherapy). Vital status and the Charlson comorbidity index (CCI) were obtained from nationwide registers. The 10-yr survival of men without prostate cancer, stratified by age and CCI, was used as a measure of the life expectancy of the men with prostate cancer. Results and limitations: The proportions receiving radical treatment varied with life expectancy among men younger than 70 yr, whereas use of these treatments did not match the long life expectancy of men in their seventies with CCI 0-1. Only 10% of men aged 75-80 yr with CCI 0 received radical treatment despite 52% probability of 10-yr life expectancy, compared with approximately half of the men younger than 70 yr with a similar life expectancy. The use of radical treatment for HRnMPCa increased with time in all Swedish counties, but a threefold difference between counties remained in 2009-2012 for patients aged 70-80 yr with CCI 0-1. Uncertain external validity is a study limitation, and the impact of physician versus patient preferences on treatment selection could not be assessed. Conclusions: Otherwise healthy men in their seventies with HRnMPCa were less likely to receive radical treatment than younger men with a similar life expectancy, although increasing use of radical treatment was observed during the study period. Our findings highlight the need for improved methods for clinical decision-making, including improved assessment of life expectancy. Patient summary: We performed a nationwide register study that showed that many healthy men in their seventies live for at least another 10 yr. Despite this long life expectancy, men in their seventies with high-risk nonmetastatic prostate cancer were often not treated with radical prostatectomy or radiotherapy, possibly because their life expectancy was underestimated. Our study highlights the need for improved clinical decision-making, which should incorporate an assessment of the patient's life expectancy.

    Methodology used in studies reporting chronic kidney disease prevalence: a systematic literature review2015In: Nephrology, Dialysis and Transplantation, ISSN 0931-0509, E-ISSN 1460-2385, Vol. 30, no S4, p. 6-16Article, review/survey (Refereed)
    Abstract [en]

    Background. Many publications report the prevalence of chronic kidney disease (CKD) in the general population. Comparisons across studies are hampered as CKD prevalence estimations are influenced by study population characteristics and laboratory methods. Methods. For this systematic review, two researchers independently searched PubMed, MEDLINE and EMBASE to identify all original research articles that were published between 1 January 2003 and 1 November 2014 reporting the prevalence of CKD in the European adult general population. Data on study methodology and reporting of CKD prevalence results were independently extracted by two researchers. Results. We identified 82 eligible publications and included 48 publications of individual studies for the data extraction. There was considerable variation in population sample selection. The majority of studies did not report the sampling frame used, and the response ranged from 10 to 87%. With regard to the assessment of kidney function, 67% used a Jaffe assay, whereas 13% used the enzymatic assay for creatinine determination. Isotope dilution mass spectrometry calibration was used in 29%. The CKD-EPI (52%) and MDRD (75%) equations were most often used to estimate glomerular filtration rate (GFR). CKD was defined as estimated GFR (eGFR) <60 mL/min/1.73 m(2) in 92% of studies. Urinary markers of CKD were assessed in 60% of the studies. CKD prevalence was reported by sex and age strata in 54 and 50% of the studies, respectively. In publications with a primary objective of reporting CKD prevalence, 39% reported a 95% confidence interval. Conclusions. The findings from this systematic review showed considerable variation in methods for sampling the general population and assessment of kidney function across studies reporting CKD prevalence. These results are utilized to provide recommendations to help optimize both the design and the reporting of future CKD prevalence studies, which will enhance comparability of study results.

    CKD Prevalence Varies across the European General Population2016In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 27, no 7, p. 2135-2147Article in journal (Refereed)
    Abstract [en]

    CKD prevalence estimation is central to CKD management and prevention planning at the population level. This study estimated CKD prevalence in the European adult general population and investigated international variation in CKD prevalence by age, sex, and presence of diabetes, hypertension, and obesity. We collected data from 19 general-population studies from 13 European countries. CKD stages 1-5 was defined as eGFR <60 ml/min per 1.73 m(2), as calculated by the CKD-Epidemiology Collaboration equation, or albuminuria >30 mg/g, and CKD stages 3-5 was defined as eGFR<60 ml/min per 1.73 m(2). CKD prevalence was age- and sex-standardized to the population of the 27 Member States of the European Union (EU27). We found considerable differences in both CKD stages 1-5 and CKD stages 3-5 prevalence across European study populations. The adjusted CKD stages 1-5 prevalence varied between 3.31% (95% confidence interval [95% CI], 3.30% to 3.33%) in Norway and 17.3% (95% Cl, 16.5% to 18.1%) in northeast Germany. The adjusted CKD stages 3-5 prevalence varied between 1.0% (95% CI, 0.7% to 1.3%) in central Italy and 5.9% (95% CI, 5.2% to 6.6%) in northeast Germany. The variation in CKD prevalence stratified by diabetes, hypertension, and obesity status followed the same pattern as the overall prevalence. In conclusion, this large-scale attempt to carefully characterize CKD prevalence in Europe identified substantial variation in CKD prevalence that appears to be due to factors other than the prevalence of diabetes, hypertension, and obesity.

    Exome-Based Rare-Variant Analyses in CKD2019In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 30, no 6, p. 1109-1122Article in journal (Refereed)
    Abstract [en]

    Background Studies have identified many common genetic associations that influence renal function and all-cause CKD, but these explain only a small fraction of variance in these traits. The contribution of rare variants has not been systematically examined. Methods We performed exome sequencing of 3150 individuals, who collectively encompassed diverse CKD subtypes, and 9563 controls. To detect causal genes and evaluate the contribution of rare variants we used collapsing analysis, in which we compared the proportion of cases and controls carrying rare variants per gene. Results The analyses captured five established monogenic causes of CKD: variants in PKD1, PKD2, and COL4A5 achieved study-wide significance, and we observed suggestive case enrichment for COL4A4 and COL4A3. Beyond known disease-associated genes, collapsing analyses incorporating regional variant intolerance identified suggestive dominant signals in CPT2 and several other candidate genes. Biallelic mutations in CPT2 cause carnitine palmitoyltransferase II deficiency, sometimes associated with rhabdomyolysis and acute renal injury. Genetic modifier analysis among cases with APOL1 risk genotypes identified a suggestive signal in AHDC1, implicated in Xia-Gibbs syndrome, which involves intellectual disability and other features. On the basis of the observed distribution of rare variants, we estimate that a two-to three-fold larger cohort would provide 80% power to implicate new genes for all-cause CKD. Conclusions This study demonstrates that rare-variant collapsing analyses can validate known genes and identify candidate genes and modifiers for kidney disease. In so doing, these findings provide a motivation for larger-scale investigation of rare-variant risk contributions across major clinical CKD categories.

    Use of Proteomics To Investigate Kidney Function Decline over 5 Years2017In: American Society of Nephrology. Clinical Journal, ISSN 1555-9041, E-ISSN 1555-905X, Vol. 12, no 8, p. 1226-1235Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND OBJECTIVES: Using a discovery/replication approach, we investigated associations between a multiplex panel of 80 circulating proteins associated with cardiovascular pathology or inflammation, and eGFR decline per year and CKD incidence.

    DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We used two cohorts, the Prospective Investigation of the Vasculature in Uppsala Seniors Study (PIVUS; n=687, mean age of 70 years, 51% women) and the Uppsala Longitudinal Study of Adult Men (ULSAM; n=360 men, mean age of 78 years), with 5-year follow-up data on eGFR. There were 231 and 206 incident cases of CKD during follow-up in the PIVUS and ULSAM studies, respectively. Proteomic profiling of 80 proteins was assessed by a multiplex assay (proximity extension assay). The assay uses two antibodies for each protein and a PCR step to achieve a high-specific binding and the possibility to measure multiple proteins in parallel, but gives no absolute concentrations.

    RESULTS: In the discovery cohort from the PIVUS Study, 28 plasma proteins were significantly associated with eGFR decline per year, taking into account the multiple testing. Twenty of these proteins were significantly associated with eGFR decline per year in the replication cohort from the ULSAM Study after adjustment for age, sex, cardiovascular risk factors, medications, and urinary albumin-to-creatinine ratio (in order of significance: TNF-related apoptosis-inducing ligand receptor 2*, CD40L receptor, TNF receptor 1*, placenta growth factor*, thrombomodulin*, urokinase plasminogen activator surface receptor*, growth/differentiation factor 15*, macrophage colony-stimulating factor 1, fatty acid-binding protein*, cathepsin D, resistin, kallikrein 11*, C-C motif chemokine 3, proteinase-activated receptor 1*, cathepsin L, chitinase 3-like protein 1, TNF receptor 2*, fibroblast growth factor 23*, monocyte chemotactic protein 1, and kallikrein 6). Moreover, 11 of the proteins predicted CKD incidence (marked with * above). No protein consistently predicted eGFR decline per year independently of baseline eGFR in both cohorts.

    CONCLUSIONS: Several circulating proteins involved in phosphate homeostasis, inflammation, apoptosis, extracellular matrix remodeling, angiogenesis, and endothelial dysfunction were associated with worsening kidney function. Multiplex proteomics appears to be a promising way of discovering novel aspects of kidney disease pathology.

    Urinary Kidney Injury Molecule-1 and the Risk of Cardiovascular Mortality in Elderly Men2014In: Clinical journal of the American Society of Nephrology : CJASN, ISSN 1555-905X, Vol. 9, no 8, p. 1393-1401Article in journal (Refereed)
    Abstract [en]

    Background and objectives

    Kidney injury molecule-1 (KIM-1) has been suggested as a clinically relevant highly specific biomarker of acute kidney tubular damage. However, community-based data on the association between urinary levels of KIM-1 and the risk for cardiovascular mortality are lacking. This study aimed to investigate the association between urinary KIM-1 and cardiovascular mortality.

    Design, setting, participants, & measurements

    This was a prospective study, using the community-based Uppsala Longitudinal Study of Adult Men (N=590; mean age 77 years; baseline period, 1997–2001; median follow-up 8.1 years; end of follow-up, 2008).

    Results

    During follow-up, 89 participants died of cardiovascular causes (incidence rate, 2.07 per 100 person-years at risk). Models were adjusted for cardiovascular risk factors (age, systolic BP, diabetes, smoking, body mass index, total cholesterol, HDL cholesterol, antihypertensive treatment, lipid-lowering treatment, aspirin treatment, and history of cardiovascular disease) and for markers of kidney dysfunction and damage (cystatin C–based eGFR and urinary albumin/creatinine ratio). Higher urinary KIM-1/creatinine (from 24-hour urine collections) was associated with a higher risk for cardiovascular mortality (hazard ratio per SD increase, 1.27; 95% confidence interval [95% CI], 1.05 to 1.54; P=0.01). Participants with a combination of high KIM-1/creatinine (upper quintile, ≥175 ng/mmol), low eGFR (≤60 ml/min per 1.73 m2), and microalbuminuria/macroalbuminuria (albumin/creatinine ratio≥3 g/mol) had a >8-fold increased risk compared with participants with low KIM-1/creatinine (<175 ng/mmol), normal eGFR (>60 ml/min per 1.73 m2), and normoalbuminuria (albumin/creatinine ratio<3 g/mol) (hazard ratio, 8.56; 95% CI, 4.17 to 17.56; P<0.001).

    Conclusions

    These findings suggest that higher urinary KIM-1 may predispose to a higher risk of cardiovascular mortality independently of established cardiovascular risk factors, eGFR, and albuminuria. Additional studies are needed to further assess the utility of measuring KIM-1 in the clinical setting.

    Soluble TNF Receptors and Kidney Dysfunction in the Elderly2014In: Journal of the American Society of Nephrology, ISSN 1046-6673, E-ISSN 1533-3450, Vol. 25, no 6, p. 1313-1320Article in journal (Refereed)
    Abstract [en]

    The importance of TNF-α and its soluble receptors (sTNFR1 and sTNFR2) in the development of kidney disease is being unraveled. Yet, community-based data regarding the role of sTNFRs are lacking. We assessed serum sTNFRs and aspects of kidney damage cross-sectionally in two independent community-based cohorts of elderly participants: Prospective Investigation of the Vasculature in Uppsala Seniors (n=815; mean age, 75 years; 51% women) and Uppsala Longitudinal Study of Adult Men (n=778; mean age, 78 years). Serum sTNFR1 correlated substantially with different aspects of kidney pathology in the Uppsala Longitudinal Study of Adult Men cohort (R=-0.52 for estimated GFR, R=0.22 for urinary albumin-to-creatinine ratio, and R=0.17 for urinary kidney injury molecule-1; P<0.001 for all), with similar correlations in the Prospective Investigation of the Vasculature in Uppsala Seniors cohort. These associations remained significant after adjustment for age, sex, inflammatory markers, and cardiovascular risk factors and were also evident in participants without diabetes. Serum sTNFR2 was associated with all three markers in the Prospective Investigation of the Vasculature in Uppsala Seniors cohort (P<0.001 for all). Our findings from two independent community-based cohorts confirm and extend results of previous studies supporting circulating sTNFRs as relevant biomarkers for kidney damage and dysfunction in elderly individuals, even in the absence of diabetes.

    Soluble Tumor Necrosis Factor Receptor 1 Is Associated with Glomerular Filtration Rate Progression and Incidence of Chronic Kidney Disease in Two Community-Based Cohorts of Elderly Individuals2015In: Cardiorenal Medicine, ISSN 1664-3828, Vol. 5, no 4, p. 278-288Article in journal (Refereed)
    Abstract [en]

    Objective: We aimed to explore and validate the longitudinal associations between soluble tumor necrosis factor receptor 1 (sTNFR1), glomerular filtration rate (GFR) progression, and chronic kidney disease (CKD) incidence in two independent community-based cohorts of elderly individuals with prespecified subgroup analyses in individuals without prevalent diabetes. Research Design and Methods: Two community-based cohorts of elderly individuals were used with 5-year follow-up data on estimated GFR: the Uppsala Longitudinal Study of Adult Men (ULSAM; n = 437 men; mean age: 78 years) and the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS; n = 703; mean age: 70 years; 51% women). GFR categories were defined as >= 60, 30-60, and = 60 ml/min/1.73 m(2) at baseline, higher sTNFRs were associated with incident CKD after 5 years in both cohorts [ULSAM: OR per SD increase 1.49 (95% CI 1.16-1.9) and PIVUS: OR 1.84 (95% CI 1.50-2.26)]. Associations were similar in individuals without diabetes. Conclusions: Higher circulating sTNFR1 independently predicts the progression to a worse GFR category and CKD incidence in elderly individuals even in the absence of diabetes. Further studies are warranted to investigate the underlying mechanisms, and to evaluate the clinical relevance of our findings.

    High Concentrations of the Angiogenic Peptide VEGF-A in Seminal Fluid and its Association to Prostasomes2016In: Clinical Laboratory, ISSN 1433-6510, Vol. 62, no 8, p. 1515-1520Article in journal (Refereed)
    Abstract [en]

    Background: Angiogenesis is the formation of new blood vessels by capillary sprouting from pre-existing vessels. This process is associated with increased expression of angiogenic factors like vascular endothelial growth factor (VEGF). The VEGF family consists of five members denoted VEGF-A, B, C, D and placenta growth factor (PlGF). Prostasomes are exosome-like extracellular vesicles existing in seminal plasma. The present study aimed at investigating the possible relationship between VEGF-A in seminal fluid and blood plasma and the prostasomal association of VEGF-A.

    Methods: Measurement of VEGF-A concentrations was carried out in seminal plasma from 40 males and in blood plasma from 40 male blood donors utilizing commercial ELISA kits. The prostasomal association of VEGF-A was investigated by flow cytometry.

    Results: We found highly elevated concentrations of VEGF-A in seminal fluid (median value 150000 pg/mL) compared with those of blood plasma. Flow cytometric analysis showed that VEGF-A is bound to the surface of prostasomes.

    Conclusions: Prostasomes and seminal plasma contain the angiogenic factor VEGF-A in high concentrations exceeding that of blood plasma by 1000 times.

    Effects of surgeon variability on oncologic and functional outcomes in a population-based setting2014In: BMC Urology, ISSN 1471-2490, E-ISSN 1471-2490, Vol. 14, p. 25-Article in journal (Refereed)
    Abstract [en]

    Background: Oncologic and functional outcomes after radical prostatectomy (RP) can vary between surgeons to a greater extent than is expected by chance. We sought to examine the effects of surgeon variation on functional and oncologic outcomes for patients undergoing RP for prostate cancer in a European center. Methods: The study comprised 1,280 men who underwent open retropubic RP performed by one of nine surgeons at an academic institution in Sweden between 2001 and 2008. Potency and continence outcomes were measured preoperatively and 18 months postoperatively by patient-administered questionnaires. Biochemical recurrence (BCR) was defined as a prostate-specific antigen (PSA) value > 0.2 ng/mL with at least one confirmatory rise. Multivariable random effect models were used to evaluate heterogeneity between surgeons, adjusting for case mix (age, PSA, pathological stage and grade), year of surgery, and surgical experience. Results: Of 679 men potent at baseline, 647 provided data at 18 months with 122 (19%) reporting potency. We found no evidence for heterogeneity of potency outcomes between surgeons (P = 1). The continence rate for patients at 18 months was 85%, with 836 of the 979 patients who provided data reporting continence. There was statistically significant heterogeneity between surgeons (P = 0.001). We did not find evidence of an association between surgeons' adjusted probabilities of functional recovery and 5-year probability of freedom from BCR. Conclusions: Our data support previous studies regarding a large heterogeneity among surgeons in continence outcomes for patients undergoing RP. This indicates that some patients are receiving sub-optimal care. Quality assurance measures involving performance feedback, should be considered. When surgeons are aware of their outcomes, they can improve them to provide better care to patients.

    Population-based study of long-term functional outcomes after prostate cancer treatment2016In: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 117, no 6B, p. E36-E45Article in journal (Refereed)
    Abstract [en]

    Objective To evaluate long-term urinary, sexual and bowel functional outcomes after prostate cancer treatment at a median (interquartile range) follow-up of 12 (11-13) years. Patients and Methods In this nationwide, population-based study, we identified 6 003 men diagnosed with localized prostate cancer (clinical local stage T1-2, any Gleason score, prostate-specific antigen <20 ng/mL, NX or N0, MX or M0) between 1997 and 2002 from the National Prostate Cancer Register, Sweden. The men were aged <= 70 years at diagnosis. A control group of 1 000 men without prostate cancer were also selected, matched for age and county of residence. Functional outcomes were evaluated with a validated self-reported questionnaire. Results Responses were obtained from 3 937/6 003 cases (66%) and 459/1 000 (46%) controls. At 12 years after diagnosis and at a median age of 75 years, the proportion of cases with adverse symptoms was 87% for erectile dysfunction/sexual inactivity, 20% for urinary incontinence and 14% for bowel disturbances. The corresponding proportions for controls were 62, 6 and 7%, respectively. Men with prostate cancer, except those on surveillance, had an increased risk of erectile dysfunction compared with the men in the control group. Radical prostatectomy was associated with an increased risk of urinary incontinence (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.36-2.62) and radiotherapy increased the risk of bowel dysfunction (OR 2.46, 95% CI 1.73-3.49) compared with men in the control group. Multimodal treatment, in particular treatment including androgen deprivation therapy (ADT), was associated with the highest risk of adverse effects; for instance, radical prostatectomy followed by radiotherapy and ADT was associated with an OR of 3.74 (95% CI 1.76-7.95) for erectile dysfunction and an OR of 3.22 (95% CI 1.93-5.37) for urinary incontinence. Conclusion The proportion of men who experienced a long-term impact on functional outcomes after prostate cancer treatment was substantial.

    Albuminuria changes are associated with subsequent risk of end-stage renal disease and mortality2017In: Kidney International, ISSN 0085-2538, E-ISSN 1523-1755, Vol. 91, no 1, p. 244-251Article in journal (Refereed)
    Abstract [en]

    Current guidelines for chronic kidney disease (CKD) recommend using albuminuria as well as estimated glomerular filtration rate (eGFR) to stage CKD. However, CKD progression is solely defined by change in eGFR with little regard to the risk implications of change in albuminuria. This is an observational study from the Stockholm CREAtinine Measurements (SCREAM) project, a health care utilization cohort from Stockholm, Sweden, with laboratory measures from 2006-2011 and follow-up through December 2012. Included were 31,732 individuals with two or more ambulatory urine albumin to creatinine ratio (ACR) tests. We assessed the association between change in ACR during a baseline period of 1, 2, or 3 years and end-stage renal disease (ESRD) or death. Using a 2-year baseline period, there were 378 ESRD events and 1712 deaths during a median of 3 years of follow-up. Compared to stable ACR, a 4-fold increase in ACR was associated with a 3.08-times (95% confidence interval 2.59 to 3.67) higher risk of ESRD while a 4-fold decrease in ACR was associated with a 0.34-times (0.26 to 0.45) lower risk of ESRD. Similar associations were found in people with and without diabetes mellitus, with and without hypertension, and also when adjusted for the change in eGFR during the same period. The association between change in ACR and mortality was weaker: ACR increase was associated with mortality, but the relationship was largely flat for ACR decline. Results were consistent for 1-, 2-, and 3-year ACR changes. Thus, changes in albuminuria are strongly and consistently associated with the risk of ESRD and death.

    Early detection of prostate cancer: AUA Guideline2013In: Journal of Urology, ISSN 0022-5347, E-ISSN 1527-3792, Vol. 190, no 2, p. 419-426Article in journal (Refereed)
    Abstract [en]

    PURPOSE:

    The guideline purpose is to provide the urologist with a framework for the early detection of prostate cancer in asymptomatic average risk men.

    MATERIALS AND METHODS:

    A systematic review was conducted and summarized evidence derived from over 300 studies that addressed the predefined outcomes of interest (prostate cancer incidence/mortality, quality of life, diagnostic accuracy and harms of testing). In addition to the quality of evidence, the panel considered values and preferences expressed in a clinical setting (patient-physician dyad) rather than having a public health perspective. Guideline statements were organized by age group in years (age <40; 40 to 54; 55 to 69; ≥ 70).

    RESULTS:

    Except prostate specific antigen-based prostate cancer screening, there was minimal evidence to assess the outcomes of interest for other tests. The quality of evidence for the benefits of screening was moderate, and evidence for harm was high for men age 55 to 69 years. For men outside this age range, evidence was lacking for benefit, but the harms of screening, including over diagnosis and overtreatment, remained. Modeled data suggested that a screening interval of two years or more may be preferred to reduce the harms of screening.

    CONCLUSIONS:

    The Panel recommended shared decision-making for men age 55 to 69 years considering PSA-based screening, a target age group for whom benefits may outweigh harms. Outside this age range, PSA-based screening as a routine could not be recommended based on the available evidence.

    Mortality after radical prostatectomy in a matched contemporary cohort in Sweden compared to the Scandinavian Prostate Cancer Group 4 (SPCG-4) study2019In: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 123, no 3, p. 421-428Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To investigate if results in terms of absolute risk in mature randomised trials are relevant for contemporary decision-making. To do so, we compared the outcome for men in the radical prostatectomy (RP) arm of the Scandinavian Prostate Cancer Group Study number 4 (SPCG-4) randomised trial with matched men treated in a contemporary era before and after compensation for the grade migration and grade inflation that have occurred since the 1980s.

    PATIENTS AND METHODS: A propensity score-matched analysis of prostate cancer mortality and all-cause mortality in the SPCG-4 and matched men in the National Prostate Cancer Register (NPCR) of Sweden treated in 1998-2006 was conducted. Cumulative incidence of prostate cancer mortality and all-cause mortality was calculated. Cox proportional hazards regression analyses were used to estimate hazard ratios (HR) and 95% confidence intervals (CIs) for a matching on original Gleason Grade Groups (GGG) and second, matching with GGG increased one unit for men in the NPCR.

    RESULTS: Matched men in the NPCR treated in 2005-2006 had half the risk of prostate cancer mortality compared to men in the SPCG-4 (HR 0.46, 95% CI 0.19-1.14). In analysis of men matched on an upgraded GGG in the NPCR, this difference was mitigated (HR 0.73, 95% CI 0.36-1.47).

    CONCLUSIONS: Outcomes after RP for men in the SPCG-4 cannot be directly applied to men in the current era, mainly due to grade inflation and grade migration. However, by compensating for changes in grading, similar outcomes after RP were seen in the SPCG-4 and NPCR. In order to compare historical trials with current treatments, data on temporal changes in detection, diagnostics, and treatment have to be accounted for.
