    Inflammatory markers in women with postpartum depressive symptoms2018Inngår i: Journal of Neuroscience Research, ISSN 0360-4012, E-ISSN 1097-4547Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Postpartum depression (PPD) is a devastating disorder affecting not only more than 10% of all women giving birth, but also the baby, the family, and the society. Compiling evidence suggests the involvement of the immune system in the pathophysiology of major depression; yet, the immune response in perinatal depression is not as well studied. The aim of this study was to investigate the alterations in peripheral levels of inflammatory biomarkers in 169 Swedish women with and without depressive symptoms according to the Edinburgh postnatal depression scale or the M.I.N.I neuropsychiatric interview at eight weeks postpartum. Among the 70 markers analyzed with multiplex proximity extension assay, five were significantly elevated in women with postpartum depressive symptoms in the adjusted LASSO logistic regression analysis: Tumor necrosis factor ligand superfamily member (TRANCE) (OR-per 1 SD increase = 1.20), Hepatocyte growth factor (HGF) (OR = 1.17) Interleukin (IL)-18 (OR = 1.06), Fibroblast growth factor 23 (FGF-23) (OR = 1.25), and C-X-C motif chemokine 1 (CXCL1) (OR 1.11). These results indicate that women with PPD have elevated levels of some inflammatory biomarkers. It is, therefore, plausible that PPD is associated with a compromised adaptability of the immune system.

    Olfactory receptor 51E1 protein as a potential novel tissue biomarker for small intestine neuroendocrine carcinomas2013Inngår i: European Journal of Endocrinology, ISSN 0804-4643, E-ISSN 1479-683X, Vol. 168, nr 2, s. 253-261Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: Late diagnosis hinders proper management of small intestine neuroendocrine carcinoma (SI-NEC) patients. The olfactory receptor, family 51, subfamily E, member 1 (OR51E1) has been reported as a potential novel SI-NEC marker, without protein expression recognition. Thus, we further studied whether the encoded protein may be a novel SI-NEC clinical biomarker.

    DESIGN: OR51E1 coding sequence was cloned using total RNA from SI-NEC patient specimens. Quantitative real-time PCR analysis explored OR51E1 expression in laser capture microdissected SI-NEC cells and adjacent microenvironment cells. Moreover, immunohistochemistry investigated OR51E1 protein expression on operation and biopsy material from primary SI-NECs, mesentery, and liver metastases from 70 patients. Furthermore, double immunofluorescence studies explored the potential co-localization of the vesicular monoamine transporter 1 (SLC18A1, generally referred to as VMAT1) and OR51E1 in the neoplastic cells and in the intestinal mucosa adjacent to the tumor.

    RESULTS: OR51E1 coding sequence analysis showed absence of mutation in SI-NEC patients at different stages of disease. OR51E1 expression was higher in microdissected SI-NEC cells than in the adjacent microenvironment cells. Furthermore, both membranous and cytoplasmic OR51E1 immunostaining patterns were detected in both primary SI-NECs and metastases. Briefly, 18/43 primary tumors, 7/28 mesentery metastases, and 6/18 liver metastases were 'positive' for OR51E1 in more than 50% of the tumor cells. In addition, co-localization studies showed that OR51E1 was expressed in >50% of the VMAT1 immunoreactive tumor cells and of the enterochromaffin cells in the intestinal mucosa adjacent to the tumor.

    CONCLUSION: OR51E1 protein is a potential novel clinical tissue biomarker for SI-NECs. Moreover, we suggest its potential therapeutic molecular target development using solid tumor radioimmunotherapy.

    Common pathogenetic mechanism involving human chromosome 18 in familial and sporadic ileal carcinoid tumors2011Inngår i: Genes, Chromosomes and Cancer, ISSN 1045-2257, E-ISSN 1098-2264, Vol. 50, nr 2, s. 82-94Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Serotonin producing endocrine carcinoma of small intestine (ileal carcinoid) is a clinically distinct endocrine tumor. It is generally considered as a sporadic disease and its molecular etiology is poorly understood. We report comprehensive clinical and molecular studies of 55 sporadic and familial patients diagnosed with this condition. Nine pedigrees encompassing 23 affected subjects were established, consistent with autosomal dominant mode of inheritance. Familial and sporadic patients demonstrated indistinguishable clinical pictures. Molecular analyses of 61 tumors from 45 individuals, including eight familial and 37 sporadic patients, aimed at determination of global copy number aberrations using BAC and Illumina SNP arrays and gene expression profiling by Affymetrix chips. Chromosome 18 aberrations were identified in both sporadic and in familial tumors; 100% vs. 38%, respectively. Other, less frequent aberrations were also common for both groups. Global expression profiles revealed no differentially expressed genes. Frequent gain of chromosome 7 was exclusively observed in metastases, when patient matched primary tumors and metastases were compared. Notably, the latter aberration correlated with solid growth pattern morphology (P < 0.01), a histopathological feature that has previously been related to worse prognosis. The clinical and molecular similarities identified between sporadic and familial cases suggest a common pathogenetic mechanism involved in tumor initiation. The familial variant of ileal carcinoid represents a previously unrecognized autosomal dominant inherited tumor disease, which we propose to call Familial Ileal Endocrine Carcinoma (FIEC). Our findings indicate the location of a FIEC tumor suppressor gene near the telomere of 18q, involved in development of inherited and sporadic tumors.

    The biological hallmarks of ileal carcinoids2011Inngår i: European Journal of Clinical Investigation, ISSN 0014-2972, E-ISSN 1365-2362, Vol. 41, nr 12, s. 1353-1360Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Endocrine tumours derived from the small intestine, ileal carcinoids, produce and secrete the hormones tachykinins and serotonin, which induces the specific symptoms related to the tumour. Because of their low proliferation rate, they are often discovered at late stages when metastases have occurred. The biology that characterizes these tumours differs in many ways from what is generally recognized for other malignancies. In this overview, the current knowledge on the development and progression of ileal carcinoids is described.

    Tachykinins in endocrine tumors and the carcinoid syndrome2008Inngår i: European Journal of Endocrinology, ISSN 0804-4643, E-ISSN 1479-683X, Vol. 159, nr 3, s. 275-282Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective

    A new antibody, active against the common tachykinin (TK) C-terminal. was used to study TK expression in patients with endocrine tumors and a possible association between plasma-TK levels and symptoms of diarrhea and flush in patients with metastasizing ileocecal serotonin-producing carcinoid tumors (MSPCs).

    Method

    TK, serotonin and chromogranin A (CgA) immunoreactivity (IR) was studied by immunohistochemistry in tissue samples from 33 midgut carcinoids and 72 other endocrine tumors. Circulating TK (P-TK) and urinary-5 hydroxyindoleacetic acid (U-5HIAA) concentrations were measured in 42 patients with MSPCs before treatment and related to symptoms in patients with the carcinoid syndrome. Circulating CgA concentrations were also measured in 39 out of the 42 patients.

    Results

    All MSPCs displayed serotonin and strong TK expression. TK-IR was also seen in all serotonin-producing lung and appendix carcinoids. None of the other tumors examined contained TK-IR cells. Concentrations of P-TK, P-CgA, and U-5HIAA were elevated in patients experiencing daily episodes of either flush or diarrhea, when compared with patients experiencing occasional or none of these symptoms. In a Spearman partial rank test, the correlation of P-TK with daily diarrhea was independent of both U-5HIAA and CgA levels.

    Conclusion

    We found that TK synthesis occurs in serotonin-IR tumors and that P-TK levels are significantly correlated with symptoms of flush and diarrhea in patients with MSPCs. This is. to our knowledge, the first report demonstrating an independent correlation of P-TKs with carcinoid diarrhea, a symptom that is customarily regarded as serotonin mediated. Further investigations may present opportunities for new therapeutic possibilities.

    Agreement between physicians' and patients' ratings on the Montgomery-Asberg Depression Rating Scale2011Inngår i: Journal of Affective Disorders, ISSN 0165-0327, E-ISSN 1573-2517, Vol. 135, nr 1-3, s. 148-153Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Self-rating scales developed for monitoring depression severity are potentially informative and cost effective tools. There is an increasing tendency to use the Montgomery-Asberg Depression Rating Scale (MADRS) and the self-rating version (MADRS-S) interchangeably.

    Methods: 400 patients with major depressive disorder were included. Concordance between patient and physician ratings was measured by means of repeated MADRS and MADRS-S ratings during a six-month drug trial and one-year follow-up.

    Results: Overall scores from patients and physicians show the same trends and both are sensitive to improvements. Our results, however, show only moderate to good agreement between patient and physician ratings. Intraclass coefficients ranged from 0.47 to 0.75 with highest agreement at week 8.

    Limitations: Generalizability is restricted to outpatients in general practice with moderate to severe depression. MADRS-S and MADRS scale definitions are similar but not identical concerning language and are scaled differently, 0-6 vs. 0-3, respectively, which may have influenced the results. The exclusion criteria restricted the range of values for the item Suicidal thoughts/Zest for life, which may have reduced the correlations.

    Conclusions: MADRS-S is a suitable tool for following patients' symptoms on a regular basis over time and may also be used to compensate for bias in physicians' ratings in drug trials.

    Predicting disagreement between physicians and patients on depression response and remission2013Inngår i: International Clinical Psychopharmacology, ISSN 0268-1315, E-ISSN 1473-5857, Vol. 28, nr 3, s. 134-140Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Demographic, personality, and disease-related factors all contribute when patients disagree with physicians on the severity of subjective symptoms. This study aims to create a model, on the basis of patient factors at treatment initiation, for longitudinal prediction of disagreement on treatment response and remission in depressed patients. Four hundred patients with major depressive disorder were studied during a clinical drug trial. Repeated assessments with the Montgomery-Asberg Depression Rating Scale (MADRS) and the self-rating version (MADRS-S) were used to indicate response or remission. Factors at baseline and week 2 were tested for inclusion in a model for the prediction of discordance on remission and response between patients and physicians at week 8. The models were then tested, in the same population, at weeks 12, 16, and 24. Model AUCs ranged from 0.71 to 0.74 for week 8. The models that were validated at weeks 12, 16, and 24 indicated stability in the predictive value of the models. The risk for longitudinal disagreement in the evaluation of depression treatment response and remission in clinical practice and drug trials can be predicted using factors at study initiation and at week 2.

    No regrets: Young adult patients in psychiatry report positive reactions to biobank participation2017Inngår i: BMC Psychiatry, ISSN 1471-244X, E-ISSN 1471-244X, Vol. 17, artikkel-id 21Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Research in vulnerable individuals must insure voluntariness and minimize negative reactions caused by participation. This study aimed to describe consent and completion rate in young psychiatric patients in relation to study components, degree of disability and to compare response to research participation in patients and controls.

    METHODS: Between 2012 and 2015, 463 patients with psychiatric disorders between the ages of 18-25 from the Dept. of General Psychiatry at Uppsala University Hospital and 105 controls were recruited to donate data and samples to a biobank. Consent and completion in relation to questionnaires, biological sampling of blood, saliva or feces, were monitored. Both groups were also asked about their perceived disability and how research participation affected them.

    RESULTS: Most patients who participated consented to and completed questionnaires and blood sampling. The majority also consented to saliva sampling, while less than half consented to collect feces. Of those who gave consent to saliva and feces only half completed the sampling. Both patients and controls reported high voluntariness and were positive to research participation. Within the patient group, those with greater perceived disability reported greater distress while participating in research, but there was no difference in consent or completion rates or level of regret.

    CONCLUSIONS: With the described information procedures, psychiatric patients, regardless of perceived disability, reported high voluntariness and did not regret participation in biobanking. Compared to questionnaires and blood sampling, given consent was reduced for feces and completion was lower for both saliva and feces sampling.

    METHODS: Between 2012 and 2015, 463 patients with psychiatric disorders between the ages of 18-25 from the Dept. of General Psychiatry at Uppsala University Hospital and 105 controls were recruited to donate data and samples to a biobank. Consent and completion in relation to questionnaires, biological sampling of blood, saliva or feces, were monitored. Both groups were also asked about their perceived disability and how research participation affected them.

    RESULTS: Most patients who participated consented to and completed questionnaires and blood sampling. The majority also consented to saliva sampling, while less than half consented to collect feces. Of those who gave consent to saliva and feces only half completed the sampling. Both patients and controls reported high voluntariness and were positive to research participation. Within the patient group, those with greater perceived disability reported greater distress while participating in research, but there was no difference in consent or completion rates or level of regret.

    CONCLUSIONS: With the described information procedures, psychiatric patients, regardless of perceived disability, reported high voluntariness and did not regret participation in biobanking. Compared to questionnaires and blood sampling, given consent was reduced for feces and completion was lower for both saliva and feces sampling.

    A MUTYH germline mutation is associated with small intestinal neuroendocrine tumors2017Inngår i: Endocrine-Related Cancer, ISSN 1351-0088, E-ISSN 1479-6821, Vol. 24, nr 8, s. 427-443Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The genetics behind predisposition to small intestinal neuroendocrine tumors (SI-NETs) is largely unknown, but there is growing awareness of a familial form of the disease. We aimed to identify germline mutations involved in the carcinogenesis of SI-NETs. The strategy included next-generation sequencing of exome- and/or whole-genome of blood DNA, and in selected cases, tumor DNA, from 24 patients from 15 families with the history of SI-NETs. We identified seven candidate mutations in six genes that were further studied using 215 sporadic SI-NET patients. The result was compared with the frequency of the candidate mutations in three control cohorts with a total of 35,688 subjects. A heterozygous variant causing an amino acid substitution p.(Gly396Asp) in the MutY DNA glycosylase gene (MUTYH) was significantly enriched in SI-NET patients (minor allele frequencies 0.013 and 0.003 for patients and controls respectively) and resulted in odds ratio of 5.09 (95% confidence interval 1.56-14.74; P value = 0.0038). We also found a statistically significant difference in age at diagnosis between familial and sporadic SI-NETs. MUTYH is involved in the protection of DNA from mutations caused by oxidative stress. The inactivation of this gene leads to specific increase of G:C- > T:A transversions in DNA sequence and has been shown to cause various cancers in humans and experimental animals. Our results suggest that p.(Gly396Asp) in MUTYH, and potentially other mutations in additional members of the same DNA excision-repair pathway (such as the OGG1 gene) might be involved in driving the tumorigenesis leading to familial and sporadic SI-NETs.

    Lower inflammatory markers in women with antenatal depression brings the M1/M2 balance into focus from a new direction2017Inngår i: Psychoneuroendocrinology, ISSN 0306-4530, E-ISSN 1873-3360, Vol. 80, s. 15-25Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Antenatal depression and use of serotonin reuptake inhibitors (SSRI) in pregnancy have both been associated with an increased risk of poor pregnancy outcomes, such as preterm birth and impaired fetal growth. While the underlying biological pathways for these complications are poorly understood, it has been hypothesized that inflammation may be a common physiological pathway. The aim of the present study was to assess peripheral inflammatory markers in healthy women, women with antenatal depression, and in women using SSRI during pregnancy.

    Methods: 160 healthy pregnant controls, 59 women with antenatal depression and 39 women on treatment with SSRIs were included. The relative levels of 92 inflammatory proteins were analyzed by proximity extension assay technology.

    Results: Overall, 23 of the inflammatory markers were significantly lower in women with antenatal depression and in women on treatment with SSRIs in comparison with the healthy controls. No difference in any of the inflammatory markers was observed between women with antenatal depression and those who were using SSRI. Top three inflammatory markers that were down-regulated in women with antenatal depression were TNF-related apoptosis-inducing ligand (TRAIL), p = 0.000001, macrophage colony-stimulating factor 1 (CSF-1), p = 0.000004, and fractalkine (CX3CL1), p =0.000005. Corresponding inflammatory markers in SSRI users were CSF-1, p = 0.000011, vascular endothelial growth factor A (VEGF-A), p =0.000016, and IL-15 receptor subunit alpha (IL-15RA), p = 0.000027. The inflammatory markers were negatively correlated with cortisone serum concentrations in controls, but not in the cases. Differential DNA methylation of was found for seven of these inflammatory markers in an independent epigenetics cohort.

    Conclusion: Women with antenatal depression or on SSRI treatment have lower levels of a number of peripheral inflammatory markers than healthy pregnant controls. Hypothetically, this could be due to dysregulated switch to the pro-M2 milieu that characterizes normal third trimester pregnancy. However, longitudinal blood sampling is needed to elucidate whether the presumably dysregulated M2 shift is driving the development of antenatal depression or is a result of the depression.

    Measurement of sCD27 in the cerebrospinal fluid identifies patients with neuroinflammatory disease2019Inngår i: Journal of Neuroimmunology, ISSN 0165-5728, E-ISSN 1872-8421, Vol. 332, s. 31-36Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Laboratory tests to assist in the diagnosis and monitoring of neuroinflammatory diseases are scarce. The soluble form of the CD27 molecule (sCD27) is shed in high concentrations by activated T cells and can be detected in the cerebrospinal fluid. The aim of this study was to investigate whether CSF quantitation of sCD27 could discriminate between inflammatory and non-inflammatory neurological diseases.

    METHODS: The concentration of sCD27 was measured using a commercially available ELISA in 803 well-defined subjects from a study cohort comprised of 338 patients with neuroinflammatory disease, 338 with non-inflammatory neurological disease and 127 controls without neurological disease.

    RESULTS: The median value of cerebrospinal fluid sCD27 was 64 pg/mL (IQR 0-200) in controls, 58 pg/mL (IQR 0-130) in patients with non-inflammatory disease and 740 pg/mL (IQR 230-1800) in patients with inflammatory disease. The likelihood ratio of having an inflammatory disease was 10 (sensitivity 74% and specificity 93%) if the sCD27 concentration was >250 pg/mL. In patients with a known inflammatory condition, the likelihood ratio of having an infection was 10 (sensitivity 40% and specificity 96%) if the sCD27 concentration was >2500 pg/mL.

    CONCLUSIONS: The likelihood of having an inflammatory neurological condition is increased with elevated concentrations of sCD27 in cerebrospinal fluid. Rapid tests of sCD27 should be developed to assist clinicians in diagnosis of neuroinflammatory disease.

    Connective tissue growth factor in tumor pathogenesis2012Inngår i: Fibrogenesis & Tissue Repair, ISSN 1755-1536, Vol. 5, nr Suppl.1, s. S8-S8Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Key roles for connective tissue growth factor (CTGF/CCN2) are demonstrated in the wound repair process where it promotes myofibroblast differentiation and angiogenesis. Similar mechanisms are active in tumor-reactive stroma where CTGF is expressed. Other potential roles include prevention of hypoxia-induced apoptosis and promoting epithelial-mesenchymal transistion (EMT). CTGF expression in tumors has been associated to both tumor suppression and progression. For example, CTGF expression in acute lymphoblastic leukemia, breast, pancreas and gastric cancer correlates to worse prognosis whereas the opposite is true for colorectal, lung and ovarian cancer. This discrepancy is not yet understood.

    High expression of CTGF is a hallmark of ileal carcinoids, which are well-differentiated endocrine carcinomas with serotonin production originating from the small intestine and proximal colon. These tumors maintain a high grade of differentiation and low proliferation. Despite this, they are malignant and most patients have metastatic disease at diagnosis. These tumors demonstrate several phenotypes potentially related to CTGF function namely: cell migration, absent tumor cell apoptosis, as well as, reactive and well vascularised myofibroblast rich stroma and fibrosis development locally and in distal organs. The presence of CTGF in other endocrine tumors indicates a role in the progression of well-differentiated tumors.

    High leptin levels are associated with migraine with aura.2016Inngår i: Cephalalgia, ISSN 0333-1024, E-ISSN 1468-2982, artikkel-id 0333102416648650Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Migraine is a prevalent disorder characterised by recurrent headache attacks preceded or accompanied by aura in a subgroup of patients. Migraine often occurs together with major depressive disorder (MDD). Alterations of adipokine levels have been reported both in migraine and in MDD. In this cross-sectional study, we aimed to assess the associations between serum leptin and adiponectin levels and migraine or migraine subtypes. Analyses were adjusted for a lifetime history of MDD in order to investigate the association between adipokines and migraine under consideration of depression status.

    METHODS: We included 3025 participants from the CoLaus/PsyCoLaus study. The impact of leptin and adiponectin levels on a diagnosis of migraine was analysed by binary regression analyses, adjusting for variables known to influence adipokine levels. Subgroup analyses were conducted based on the presence of aura.

    RESULTS: Crude leptin levels were significantly higher in subjects with migraine than controls (Mann-Whitney U = 515,102, p = 6 × 10(-7)). When performing adjusted analyses, leptin levels were found to be significantly higher in subjects with migraine (odds ratio = 1.22, p = 0.024) and migraine with aura (odds ratio = 1.34, p = 0.004).

    CONCLUSION: High leptin levels might play a role in the pathogenesis of migraine and migraine with aura.

    High leptin levels are associated with migraine with aura2017Inngår i: Cephalalgia, ISSN 0333-1024, E-ISSN 1468-2982, Vol. 37, nr 5, s. 435-441Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Migraine is a prevalent disorder characterised by recurrent headache attacks preceded or accompanied by aura in a subgroup of patients. Migraine often occurs together with major depressive disorder (MDD). Alterations of adipokine levels have been reported both in migraine and in MDD. In this cross-sectional study, we aimed to assess the associations between serum leptin and adiponectin levels and migraine or migraine subtypes. Analyses were adjusted for a lifetime history of MDD in order to investigate the association between adipokines and migraine under consideration of depression status.

    METHODS: We included 3025 participants from the CoLaus/PsyCoLaus study. The impact of leptin and adiponectin levels on a diagnosis of migraine was analysed by binary regression analyses, adjusting for variables known to influence adipokine levels. Subgroup analyses were conducted based on the presence of aura.

    RESULTS: Crude leptin levels were significantly higher in subjects with migraine than controls (Mann-Whitney U = 515,102, p = 6 × 10(-7)). When performing adjusted analyses, leptin levels were found to be significantly higher in subjects with migraine (odds ratio = 1.22, p = 0.024) and migraine with aura (odds ratio = 1.34, p = 0.004).

    CONCLUSION: High leptin levels might play a role in the pathogenesis of migraine and migraine with aura.

    Daytime Melatonin Levels in Saliva are Associated with Inflammatory Markers and Anxiety Disorders in Young Adults with Psychiatric DiseaseManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    The bidirectional interaction between melatonin and the immune system has largely gone unexplored in a clinical context and especially in a psychiatric population. This study explored the association between melatonin during the day and inflammatory cytokines in young adult patients seeking psychiatric care. Samples and data were collected from 108 young adults (mean age 21, SD=2) at an outpatient clinic for affective disorders. Daytime saliva melatonin levels were analyzed with enzyme-linked immunosorbent assay in relation to normalized serum expression levels of 72 inflammatory markers in a proximity extension assay. In a post hoc analysis, the markers with a significant association with melatonin were tested in a generalized linear model to see whether there is a relationship to anxiety disorder or depression. After Bonferroni correction for multiple testing, melatonin levels at 11:00 were positively correlated with cluster of differentiation 5 (CD5; p=4.2e-4, p adj=0.03). Melatonin levels after lunch were correlated with monocyte chemoattractant protein-1 (MCP-1; p=4.2e-4p adj=0.03), monocyte inflammatory protein-1 alpha (MIP-1α; p=6.5e-4p adj=0.047) and vascular endothelial growth factor A (VEGF-A; p=5.3e-6p adj=0.004). In the generalized linear model, positive associations were found between the presence of any anxiety disorder after lunch and melatonin (p=0.046), VEGF-A (p=0.001) and MIP-1α (p=0.001). Daytime saliva levels of melatonin were related to several inflammatory markers in psychiatric patients. This observation likely reflects the bidirectional relationship between melatonin production and the immune system. These findings may have relevance for the understanding of psychiatric disorders and other disorders associated with the same underlying pathogenesis, including low-grade inflammation.

    Direct-acting antiviral treatment in real world patients with hepatitis C not associated with psychiatric side effects: a prospective observational study2018Inngår i: BMC Psychiatry, ISSN 1471-244X, E-ISSN 1471-244X, Vol. 18, artikkel-id 157Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Treatment of Hepatitis C virus (HCV) infection has evolved from interferon (IFN)-based treatments to direct-acting antivirals (DAAs). Patients with HCV have an elevated psychiatric morbidity (including substance abuse) and patients with such comorbidity have often been excluded from treatment with IFN. To date, little is known about psychiatric adverse effects of DAA-based regimens. We therefore aimed to study the psychiatric side effects of new IFN-free treatment for HCV (including depressive symptoms and sleep) in real world patients also including those with a history of psychiatric diagnosis, substance abuse or drug dependence. Methods: Consecutive patients were monitored during treatment with three of the latest DAA agents (sofosbuvir, simeprevir and daclatasvir). Repeated expert psychiatric assessments from baseline to 12 weeks post-treatment were performed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) clinical version and the self-report versions of the Montgomery Asberg Depression Rating Scale (MADRS-S) and the Pittsburgh Sleep Quality Index (PSQI). Friedman's test was performed to calculate differences in the MADRS-S and PSQI over time. In a post-hoc analysis Wilcoxon's test was used to compare baseline depressive symptoms with those at post-treatment. Spearman's rank correlation test was conducted in another post-hoc analysis to evaluate the correlation between symptoms of depression and HCV viral load at baseline. Results: At baseline, 15/17 patients (88%) had a history of any psychiatric diagnosis; 11 (65%) had a history of substance abuse or dependence; and 11 (65%) had previously been treated with IFN and six of those had experienced psychiatric side effects. There was no correlation between depressive symptoms and HCV viral load at baseline. Symptoms of depression did not increase during DAA treatment and were lower 12 weeks post-treatment compared with baseline: MADRS-S 10.7 vs. 8.3 (p = 0.01). This observation held when excluding patients taking antidepressant medication. Sleep quality did not significantly change during treatment. Adherence to treatment was estimated to 95% and sustained virological response was 88%. Conclusions: Despite high psychiatric morbidity, including previous substance abuse, patients successfully completed DAA treatment without increasing depressive symptoms or sleep disturbance. Symptoms of depression were significantly reduced 12 weeks after DAA treatment.

    Salivary Melatonin in Relation to Depressive Symptom Severity in Young Adults.2016Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 11, nr 4, artikkel-id e0152814Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Reduced levels of melatonin have been associated with severe depression. The aim was to investigate the correlation between salivary melatonin and dimensional measures of depressive symptom severity in young adult psychiatric patients. Levels of melatonin were analyzed in six saliva samples during waking hours from 119 young adult patients under outpatient psychiatric care. Melatonin levels were tested for association with the severity of depressive symptoms using the self-rating version of the Montgomery Åsberg Depression Rating Scale (MADRS-S). Where possible, depressive symptoms were assessed again after 6±2 months of treatment. Response was defined as decrease in MADRS-S by ≥50% between baseline and follow-up. Patients with levels of melatonin in the lowest quartile at bedtime had an increased probability of a high MADRS-S score compared to those with the highest levels of melatonin (odds ratio 1.39, 95% CI 1.15-1.69, p<0.01). A post hoc regression analysis found that bedtime melatonin levels predicted response (odds ratio 4.4, 95% CI 1.06-18.43, p<0.05). A negative relationship between salivary melatonin and dimensional measures of depressive symptom severity was found in young patients under outpatient psychiatric care. Bedtime salivary melatonin levels may have prognostic implications.

    Plasma levels of leptin and adiponectin and depressive symptoms in young adults2019Inngår i: Psychiatry Research, ISSN 0165-1781, E-ISSN 1872-7123, Vol. 272, s. 1-7Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Circulating levels of adipokines are known to be associated with depression. This study aimed to investigate a possible association between leptin, adiponectin and dimensional measures of depressive symptoms in young adults with and without psychiatric illness. Total plasma adiponectin and leptin levels were measured in 194 young adults seeking psychiatric ambulatory care and 57 healthy controls. Depressive symptoms were assessed using the Montgomery-Åsberg Depression Self-Rating Scale (MADRS-S). Analysis was performed on men and women separately. P-leptin levels were significantly elevated in patients compared with controls and correlated with total MADRS-S scores in the women. Women with P-leptin in the highest quartile reached a significantly higher MADRS-S score than women in the lowest quartile, but this difference disappeared after adjusting for body mass index (BMI) and antidepressant use. MADRS-S score was associated with P-leptin in female patients without antidepressant use, independently of BMI. There was no association between P-leptin levels and current major depression. P-adiponectin levels were not associated with depressive symptoms or current major depression. The findings indicate that P-leptin levels are associated with depressive symptom severity in young women; however, the association is linked to other factors, which challenges its usefulness as a biomarker for depression in clinical psychiatry.

    Elevated total plasma-adiponectin is stable over time in young women with bulimia nervosa2017Inngår i: European psychiatry, ISSN 0924-9338, E-ISSN 1778-3585, Vol. 41, s. 30-36Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Bulimia nervosa (BN) is characterized by dysregulated eating behaviour and present data suggest adipokines may regulate food intake. We investigated a possible association between BN and adipokine levels and hypothesized that plasma (P)-adiponectin would be elevated and P-leptin and P-leptin-adiponectin-ratio would be reduced in women with BN.

    METHODS: The study was designed as a cross-sectional study with a longitudinal arm for patients with BN. Plasma-adiponectin and leptin was measured in 148 female patients seeking psychiatric ambulatory care and 45 female controls. Fifteen patients were diagnosed with BN and the remaining with other affective and anxiety disorders. P-adiponectin and P-leptin levels were compared between patients with BN, patients without BN and controls. At follow-up 1-2years later, adipokines were reassessed in patients with BN and the Eating Disorder Examination Questionnaire was used to assess symptom severity.

    RESULTS: P-adiponectin was elevated in patients with BN at baseline and at follow-up when compared to patients without BN and controls (P<0.004 and <0.008 respectively). The difference remained significant after controlling for body mass index. P-adiponectin was correlated to symptom severity at follow-up in patients with BN without morbid obesity (ρ=0.72, P<0.04). P-leptin-adiponectin-ratio was significantly lower in patients with BN compared to controls (P<0.04) and P-leptin non-significantly lower.

    CONCLUSIONS: Findings indicate a stable elevation of P-adiponectin in women with BN. P-adiponectin at follow-up correlates to eating disorder symptom severity in patients without morbid obesity, indicating that P-adiponectin should be further investigated as a possible potential prognostic biomarker for BN.

    Human Gastroenteropancreatic Expression of Melatonin and Its Receptors MT1 and MT22015Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, nr 3, artikkel-id e0120195Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background and Aim The largest source of melatonin, according to animal studies, is the gastrointestinal (GI) tract but this is not yet thoroughly characterized in humans. This study aims to map the expression of melatonin and its two receptors in human GI tract and pancreas using microarray analysis and immunohistochemistry. Method Gene expression data from normal intestine and pancreas and inflamed colon tissue due to ulcerative colitis were analyzed for expression of enzymes relevant for serotonin and melatonin production and their receptors. Sections from paraffin-embedded normal tissue from 42 individuals, representing the different parts of the GI tract (n= 39) and pancreas (n= 3) were studied with immunohistochemistry using antibodies with specificity for melatonin, MT1 and MT2 receptors and serotonin. Results Enzymes needed for production of melatonin are expressed in both GI tract and pancreas tissue. Strong melatonin immunoreactivity (IR) was seen in enterochromaffin (EC) cells partially co-localized with serotonin IR. Melatonin IR was also seen in pancreas islets. MT1 and MT2 IR were both found in the intestinal epithelium, in the submucosal and myenteric plexus, and in vessels in the GI tract as well as in pancreatic islets. MT1 and MT2 IR was strongest in the epithelium of the large intestine. In the other cell types, both MT2 gene expression and IR were generally elevated compared to MT1. Strong MT2, IR was noted in EC cells but not MT1 IR. Changes in gene expression that may result in reduced levels of melatonin were seen in relation to inflammation. Conclusion Widespread gastroenteropancreatic expression of melatonin and its receptors in the GI tract and pancreas is in agreement with the multiple roles ascribed to melatonin, which include regulation of gastrointestinal motility, epithelial permeability as well as enteropancreatic cross-talk with plausible impact on metabolic control.

    The Relationship Between Daytime Salivary Melatonin and Gastrointestinal Symptoms in Young Adults Seeking Psychiatric Care2019Inngår i: Psychosomatic Medicine, ISSN 0033-3174, E-ISSN 1534-7796, Vol. 81, nr 1, s. 51-56Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: The pathophysiology of irritable bowel syndrome (IBS) is not completely understood, although we do know that patients with IBS have a high prevalence of psychiatric comorbidity (mainly depression and anxiety disorders). Melatonin, produced in the gastrointestinal tract, influences gutmotility. Psychiatric conditions are associated with circadian disturbances in peripheral melatonin levels. This study aimed to investigate associations between daytime salivary melatonin and gastrointestinal symptoms in young adult psychiatric patients.

    Methods: Ninety-six patients (86% women), aged 18-25 years (M (SD) = 21 (2)), seeking psychiatric care with primarily anxiety disorders, affective disorders, or both were included in the study. Total scores from the Gastrointestinal Symptoms Rating Scale -IBS were compared with salivary melatonin measured at three time points (30 minutes after waking up, at 11: 00 hours and 30 minutes after lunch) during the waking hours of 1 day.

    Results: After adjustment for potential confounders, melatonin levels in saliva 30 minutes after lunch remained significantly correlated to the total Gastrointestinal Symptoms Rating Scale -IBS score after correction for multiple testing (B = 0.016, SE = 0.006, p =.015, q = 0.045). In a post hoc analysis, symptoms of gastrointestinal pain and bloating contributed most to this association.

    Conclusions: In young adult psychiatric patients, salivary melatonin levels after lunch are associated with gastrointestinal symptoms, which is consistent with the proposed effect of elevated levels of gastrointestinal melatonin on gut motility. This result suggests a link between IBS symptoms and regulation of melatonin in patients with psychiatric disorders.

    Melatonin Immunoreactivity in Malignant Small Intestinal Neuroendocrine Tumours2016Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 11, nr 10, artikkel-id e0164354Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background/ Aims Small intestinal neuroendocrine tumours (SI-NETs) are derived from enterochromaffin cells. After demonstrating melatonin in enterochromaffin cells, we hypothesized that SI-NETs may express and secrete melatonin, which may have an impact on clinical factors and treatment response. Methods Tumour tissue from 26 patients with SI-NETs, representing paired sections of primary tumour and metastasis, were immunohistochemically stained for melatonin and its receptors, MT1 and MT2. Plasma melatonin and immunoreactivity (IR) for melatonin, MT1 and MT2 in tumour cells were compared to other tumour markers and clinical parameters. Melatonin was measured at two time points in fasting morning plasma from 43 patients with SI-NETs. Results Melatonin IR was found in all SI-NETS. Melatonin IR intensity in primary tumours correlated inversely to proliferation index (p = 0.022) and patients reported less diarrhoea when melatonin IR was high (p = 0.012). MT1 IR was low or absent in tumours. MT2 expression was medium to high in primary tumours and generally reduced in metastases (p = 0.007). Plasma-melatonin ranged from 4.5 to 220.0 pg/L. Higher levels were associated with nausea at both time points (p = 0.027 and p = 0.006) and flush at the second sampling. In cases with disease stabilization or remission (n = 34), circulating melatonin levels were reduced in the second sample (p = 0.038). Conclusion Immunoreactive melatonin is present in SI-NETs. Circulating levels of melatonin in patients with SI-NETs are reduced after treatment. Our results are congruent with recent understanding of melatonin's endocrine and paracrine functions and SI-NETs may provide a model for further studies of melatonin function.

    A pilot genome-wide association study shows genomic variants enriched in the non-tumor cells of patients with well-differentiated neuroendocrine tumors of the ileum2011Inngår i: Endocrine-Related Cancer, ISSN 1351-0088, E-ISSN 1479-6821, Vol. 18, nr 1, s. 171-180Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Genetic studies of midgut carcinoid cancer have exclusively focused on genomic changes of the tumor cells. We investigated the role of constitutional genetic polymorphisms in predisposing individuals to ileal carcinoids. In all, 239 cases and 110 controls were collected from three institutions: the Uppsala University Hospital; the Dana-Farber Cancer Institute; and the MD Anderson Cancer Center, and were genotyped using microarrays assaying >300 000 single nucleotide polymorphisms. Association with rs2208059 in KIF16B approached statistical significance (Mantel-Haenszel odds ratio=2.42, P=4.16×10−7) at a Bonferroni-corrected level (<1.62×10−7). Using two computational algorithms, four copy-number variants (CNVs) were identified in multiple cases that were absent in study controls and markedly less frequent in ∼1500 population-based controls. Of these four constitutional CNVs identified in blood-derived DNA, a 40 kb heterozygous deletion in Chr18q22.1 corresponded with a region frequently showing loss of heterozygosity (LOH) in ileal carcinoid tumor cells based on our meta-analysis of previously published cytogenetic studies (69.7% LOH, 95% confidence interval=60.0–77.9%). We analyzed the constitutional 40 kb deletion on chr18 in our study samples with a real-time quantitative PCR assay; 14/226 cases (6.19%) and 2/97 controls (2.06%) carried the CNV, although the exact boundaries of each deletion have not been determined. Given the small sample size, our findings warrant an independent cohort for a replication study. Owing to the rarity of this disease, we believe these results will provide a valuable resource for future work on this serious condition by allowing others to make efficient use of their samples in targeted studies.

    Elevated Plasma Chromogranin A is the First Indication of Recurrence in Radically Operated Midgut Carcinoid Tumours2009Inngår i: Neuroendocrinology, ISSN 0028-3835, E-ISSN 1423-0194, Vol. 89, nr 3, s. 302-307Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background:

    Patients with malignant midgut carcinoids are occasionally diagnosed with limited tumor spread, and surgery with radical intention is performed. Despite curative intent, recurrences occur frequently, motivating long-term biochemical and radiological follow-up. This study aimed to compare the usefulness of various methods in detecting such recurrences.

    Methods:

    This retrospective study included 56 patients with radically operated midgut carcinoids referred to our University Hospital for evaluation and follow-up between 1985 and 2004. Patients were monitored 1-3 times per year using plasma-chromogranin A (P-CgA), urinary 5-hydroxyindoleacetic acid (U-5HIAA) concentrations as well as radiological examinations, including ultrasonography, computerized tomography or magnetic resonance investigation. In a subset of cases, somatostatin receptor scintigraphy and/or positron emission tomography with 5-hydroxytryptophan was performed. Time from operation until established recurrence was recorded.

    Results:

    Tumor recurrence was established in 33 of 56 patients after a median of 32 months (range 6-217). Elevated P-CgA was the first marker to become pathologically elevated in 28 of these 33 patients (85%). In 3 of these 28 patients, radiology was simultaneously positive for a recurrence.

    Conclusion:

    P-CgA was the first marker to indicate tumor recurrence in the majority of radically operated midgut carcinoid patients. To avoid unnecessary and costly examinations in asymptomatic patients, we suggest that follow-up should comprise measurements of P-CgA twice a year and annual ultrasonography until P-CgA is elevated or clinical symptoms occur, at which time all efforts should be made to identify recurrent tumor lesions in order to give the patient the best possible treatment which, if possible, should be surgical removal of the recurrence.
