    Long-term outcome of infliximab treatment in chronic active ulcerative colitis: a Swedish multicentre study of 250 patients2017In: Alimentary Pharmacology and Therapeutics, ISSN 0269-2813, E-ISSN 1365-2036, Vol. 45, no 4, 519-532 p.Article in journal (Refereed)
    Abstract [en]

    Background Real-life long-term data on infliximab treatment in ulcerative colitis are limited. Aim To study the long-term efficacy and safety of infliximab in chronic active ulcerative colitis and possible predictors of colectomy and response were also examined. Methods A retrospective multi-centre study of infliximab treatment in 250 patients with chronic active ulcerative colitis with inclusion criteria: age 18 years, ambulatory treated, steroid-dependent or intolerant and/or immunomodulator refractory or intolerant. Results Steroid-free clinical remission was achieved by 123/250 patients (49.2%) at 12 months and in 126/250 patients at a median follow-up of 2.9 years (50.4%). Primary response at 3 months was achieved by 190/250 (76.0%) patients and associated with a high probability of response 168/190 (88.4%) at 12 months and 143/190 (75.3%) at follow-up. Long-term rate of colectomy in primary responders was 6/190 (3.2%) at 12 months and 27/190 (14.2%) at last follow-up. Failure to achieve response at 3 months was associated with a high risk of subsequent colectomy, 29/60 (48.3%) at 12 months and 41/60 (68.3%) at follow-up. Response at 12 months was associated with a low risk of subsequent colectomy, 14/181 (7.7%) compared with non-response 19/34 (55.9%) (P < 0.0001). Non-response at 3 months was an independent predictor of subsequent colectomy (HR = 9.40, 95% CI = 5.10-17.35, P < 0.001). Concomitant azathioprine therapy did not influence outcome in terms of colectomy. Conclusions Long-term efficacy of infliximab treatment in chronic active ulcerative colitis is excellent especially in patients who respond to induction treatment. Conversely, non-response at 3 months predicts a poor outcome, with a high risk of subsequent colectomy.

    Long-term effectiveness of vedolizumab in inflammatory bowel disease: a national study based on the Swedish National Quality Registry for Inflammatory Bowel Disease (SWIBREG)2017In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 52, no 6-7, 722-729 p.Article in journal (Refereed)
    Abstract [en]

    Objectives: Clinical trials have demonstrated the efficacy of vedolizumab in inflammatory bowel disease (IBD). However, these findings may not reflect the clinical practice. Therefore, we aimed to describe a vedolizumab-treated patient population and assess long-term effectiveness.Materials and methods: Patients initiating vedolizumab between 1 June 2014 and 30 May 2015 were identified through the Swedish National Quality Registry for IBD. Prospectively collected data on treatment and disease activity were extracted. Clinical remission was defined as Patient Harvey Bradshaw index<5 in Crohn's disease (CD) and Patient Simple Clinical Colitis Activity index<3 in ulcerative colitis (UC).Results: Two-hundred forty-six patients (147CD, 92 UC and 7 IBD-Unclassified) were included. On study entry, 86% had failed TNF-antagonist and 48% of the CD patients had undergone1 surgical resection. After a median follow-up of 17 (IQR: 14-20) months, 142 (58%) patients remained on vedolizumab. In total, 54% of the CD- and 64% of the UC patients were in clinical remission at the end of follow-up, with the clinical activity decreasing (p<.0001 in both groups). Faecal-calprotectin decreased in CD (p<.0001) and in UC (p=.001), whereas CRP decreased in CD (p=.002) but not in UC (p=.11). Previous anti-TNF exposure (adjusted HR: 4.03; 95% CI: 0.96-16.75) and elevated CRP at baseline (adjusted HR: 2.22; 95% CI: 1.10-4.35) seemed to be associated with discontinuation because of lack of response. Female sex was associated with termination because of intolerance (adjusted HR: 2.75; 95% CI: 1.16-6.48).Conclusion: Vedolizumab-treated patients represent a treatment-refractory group. A long-term effect can be achieved, even beyond 1 year of treatment.

    Clinical course of Crohn's disease during the first 5 years. Results from a population-based cohort in Sweden (ICURE) diagnosed 2005-20092017In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 52, no 1, 81-86 p.Article in journal (Refereed)
    Abstract [en]

    Objective: The aim of the study was to describe the medical treatment, change in phenotype, need for surgery and IBD-associated mortality during the first 5 years after diagnosis. Material and Methods: Patients diagnosed with Crohn's disease including all age groups in the Uppsala healthcare region in the middle of Sweden 2005-2009 were included in the study. Medical notes were scrutinised and patients contacted. Out of 269 patients, 260 (96.3%) could be followed for 5 full years or until death. Results: The following drugs were used: 5-ASA 66.7%, systemic steroids 76.4%, antimetabolites 56.7% and anti-TNF 20.3%. Described with the Montreal classification, the proportion with inflammatory behaviour decreased from 78.1% to 74.0% from diagnosis to end of the observation, patients with stricturing behaviour increased from 13.0% to 15.4% and patients with penetrating behaviour increased from 8.9% to 10.6%. After the first year, 12.4% had been treated with intestinal resection or colectomy, a figure that increased to 14.8 after 5 years. Two patients suffered an IBD-related death. Conclusions: Compared to similar patient cohorts, the present study demonstrates that although the course of Crohn's disease seems difficult to change during the first year after diagnosis, the following years up to 5 years shows a more benign course than has usually been described earlier.

    Low colectomy rate five years after diagnosis of ulcerative colitis. Results from a prospective population-based cohort in Sweden (ICURE) diagnosed during 2005-2009*2016In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 51, no 11, 1339-1344 p.Article in journal (Refereed)
    Abstract [en]

    Objective: The medical treatment of ulcerative colitis (UC) has seen a change towards a more active attitude during recent years, including both the use of more traditional drugs as well as new biological substances. In this epidemiological study we have evaluated the results of modern treatment of UC in a population-based cohort of patients including all age groups, with regard to relapse rate, colectomy and IBD-associated mortality.

    Material and methods: Patients diagnosed with UC in the Uppsala health care region in the middle of Sweden during 2005-2009 were included in the study. Out of 524 patients, 491 (93%) could be followed for five full years or until death.

    Results: Nineteen patients (3.9%) had died and two of these deaths could be attributed to UC (one postoperative death and one colonic carcinoma). The following drugs were used by the patients during the study period: 5-ASA (91%), systemic steroids (66%), immunomodulators (IMM), mainly thiopurines (26%) and anti-TNF (11%). During the observation period, 74% experienced at least one relapse and 5.3% were subjected to colectomy. Among patients<17 years at diagnosis, colectomy was performed in two (4.8%).

    Conclusions: Five years after diagnosis of ulcerative colitis, 5.3% had been subjected to colectomy and two patients (0.38%) had died because of the disease.

    Active cytomegalovirus infection diagnosed by real-time PCR in patients with inflammatory bowel disease: a prospective, controlled observational study2016In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 51, no 9, 1075-1080 p.Article in journal (Refereed)
    Abstract [en]

    Objective: It is assumed that cytomegaloviral (CMV) infection in inflammatory bowel disease (IBD) is caused by reactivation due to the immunosuppressive therapy, but the role of CMV as a pathophysiological factor and prognostic marker in IBD is unclear. The aim of this study was to investigate CMV infection in IBD, with real-time polymerase chain reaction (PCR) and immunohistochemistry, with emphasis on newly diagnosed disease.

    Materials and methods: In this prospective, controlled study, 67 patients with IBD and 34 control patients with irritable bowel syndrome (IBS) or rectal bleeding were included. Serology for CMV was analysed along with CMV DNA in plasma, mucosal biopsies, and faeces. Mucosal biopsies were further analysed with histopathology and CMV immunohistochemistry.

    Results: Detection of CMV IgM was more common in patients with IBD, compared to controls, 21% versus 3%. CMV DNA was found in 16% of patients with newly diagnosed, untreated IBD and in 38% of steroid-treated patients. Four of the five patients that needed urgent surgery were CMV-DNA positive in at least one of three sample types. None of the controls had detectable CMV DNA.

    Conclusions: Active CMV infection was found in high proportions of newly diagnosed untreated patients with IBD, in patients on immunosuppression and in patients in the need of surgery. Low CMV-DNA levels in non-immunosuppressed patients were not a risk factor for the development of more severe IBD, while the detection of CMV DNA in patients on immunosuppressive therapy may foresee disease progression.

    Microscopic colitis in Uppsala health region, a population-based prospective study 2005-20092013In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, Vol. 48, no 7, 825-830 p.Article in journal (Refereed)
    Abstract [en]

    Objective

    The aim of this study is to report on the incidence of microscopic colitis (MC), any possible relation with inflammatory bowel disease (IBD), concomitant drug consumption, related diseases and the clinical course of the diseases.

    Methods

    Both new cases of IBD and MC were registered at the same time in the same geographical area. The study started in the county of Uppsala 2005-2006, and other parts of the surrounding health region were included 2007-2009. Established morphological criteria were used, i.e. a layer of subepithelial collagen band >= 10 mu m in collagenous colitis (CC) with concomitant inflammation and at least 20 lymphocytes per 100 epithelial cells in lymphocytic colitis (LC).

    Results

    The authors found 272 new cases of MC, 154 with CC and 118 with LC. The mean age-adjusted incidence was 7.0/1,000,000 for CC and 4.8/100,000 for LC. The clinical course was dominated by single episodes with diarrhea or intermittent symptoms, but 14% suffered from chronic diarrhea. In 10% of the cases, diagnosis was made in individuals without chronic watery diarrhea. Although not systematically tested, concomitant celiac disease was found in approximately 5% of the patients.

    Conclusions

    The incidence of MC in Uppsala health region is similar to other studied areas. The majority of patients had a self-limiting or easily treated condition, but 14% need a more or less continuous medication. Ten percent of the patients demonstrate other symptoms than chronic watery diarrhea. The possibility of concomitant celiac disease should be considered in new cases of MC.
