- Increasing evidence suggests that a combination of host genetics and the composition of the gut microbiota are important for development of Crohn's disease (CD). Our aim was to study identical twins with CD to determine microbial factors independent of host genetics. Fecal samples were studied from 10 monozygotic twin pairs with CD (discordant n=6 and concordant n=4) and 8 healthy twin pairs. DNA was extracted, 16S rRNA genes were PCR amplified and T-RFLP fingerprints generated using general bacterial and Bacteroides group-specific primers. The microbial communities were also profiled based on their percentage G+C contents. Bacteroides 16S rRNA genes were cloned and sequenced from a subset of the samples. The bacterial diversity in each sample and similarity indices between samples were estimated based on the T-RFLP data using a combination of statistical approaches. Healthy individuals had a significantly higher bacterial diversity compared to individuals with CD. The fecal microbial communities were more similar between healthy twins than between twins with CD, especially when these were discordant for the disease. The microbial community profiles of individuals with ileal CD were significantly different from healthy individuals and those with colonic CD. Also, CD individuals had a lower relative abundance of B. uniformis and higher relative abundances of B. ovatus and B. vulgatus. Our results suggest that genetics and/or environmental exposure during childhood, in part, determine the gut microbial composition. However, CD is associated with dramatic changes in the gut microbiota and this was particularly evident for individuals with ileal CD.

- Background The long-term efficacy of infliximab as rescue therapy in steroid-refractory ulcerative colitis is not well described. Aim To examine the long-term efficacy of infliximab as a rescue therapy through a 3-year follow-up of a previous placebo-controlled trial of infliximab in acute steroid-refractory ulcerative colitis. Method In the original study, 45 patients were randomized to a single infusion of infliximab 5 mg/kg or placebo, and at 3 months, 7/24 patients given infliximab were operated vs. 14/21 patients given placebo. Three years or later, patients were asked to participate in a clinical follow-up. Results Another seven patients underwent colectomy during follow-up: five in the infliximab group and two in the placebo group. After 3 years, a total of 12/24 (50%) patients given infliximab and 16/21 (76%) given placebo (P = 0.012) had a colectomy. None of eight patients in endoscopic remission at 3 months later had a colectomy compared with 7/14 (50%) patients who were not in remission (P = 0.02). There was no mortality. Conclusion The benefit of rescue therapy with infliximab in steroid-refractory acute ulcerative colitis remained after 3 years. The main advantage of infliximab treatment occurred during the first 3 months, whereas subsequent colectomy rates were similar in the two groups. Mucosal healing at 3 months influenced later risk of colectomy.

- Objective: This 1-year study aimed to assess low-dose budesonide therapy for maintenance of clinical remission in patients with collagenous colitis.Design: A prospective, randomised, placebo-controlled study beginning with an 8-week open-label induction phase in which patients with histologically confirmed active collagenous colitis received budesonide (Budenofalk, 9 mg/day initially, tapered to 4.5 mg/day), after which 92 patients in clinical remission were randomised to budesonide (mean dose 4.5 mg/day; Budenofalk 3 mg capsules, two or one capsule on alternate days) or placebo in a 12-month double-blind phase with 6 months treatment-free follow-up. Primary endpoint was clinical remission throughout the double-blind phase.Results: Clinical remission during open-label treatment was achieved by 84.5% (93/110 patients). The median time to remission was 10.5 days (95% CI (9.0 to 14.0 days)). The maintenance of clinical remission at 1 year was achieved by 61.4% (27/44 patients) in the budesonide group versus 16.7% (8/48 patients) receiving placebo (treatment difference 44.5% in favour of budesonide; 95% CI (26.9% to 62.7%), p<0.001). Health-related quality of life was maintained during the 12-month double-blind phase in budesonide-treated patients. During treatment-free follow-up, 82.1% (23/28 patients) formerly receiving budesonide relapsed after study drug discontinuation. Low-dose budesonide over 1 year resulted in few suspected adverse drug reactions (7/44 patients), all non-serious.Conclusions: Budesonide at a mean dose of 4.5 mg/day maintained clinical remission for at least 1 year in the majority of patients with collagenous colitis and preserved health-related quality of life without safety concerns. Treatment extension with low-dose budesonide beyond 1 year may be beneficial given the high relapse rate after budesonide discontinuation.

- BACKGROUND: Health-related quality of life (HRQoL) is an essential part of inflammatory bowel disease (IBD) assessment. The Short Health Scale (SHS), an HRQoL questionnaire in which the patients rate the disease impact on 4 important aspects of subjective health (symptoms, function, worry, and general well-being) was demonstrated in a previous study to be valid, reliable, and responsive in patients with ulcerative colitis. The present study evaluates the SHS in patients with Crohn's disease (CD). METHODS: In all, 367 CD patients completed the SHS and 4 other HRQoL questionnaires (IBDQ, SF-36, RFIPC, and PGWB) at their regular outpatient visits. Then 330 patients completed the questionnaires at a second visit 6 months later. In addition, reliability data were obtained from repeat measurements 4 weeks after the first visit in 40 patients stable in remission. RESULTS: Patients in remission scored better on all 4 questions than those with active disease (P < 0.001). All 4 questions were strongly correlated with the corresponding dimensions of the other HRQoL questionnaires (r(s) = 0.74-0.83). Reliability was confirmed with strong test-retest correlations (r(s) = 0.69-0.82) and intraclass correlation coefficients (0.66-0.77). Patients who changed from remission to active disease or vice versa showed a significant change in all 4 SHS scores (P < 0.005). CONCLUSIONS: SHS is a valid, reliable and responsive HRQoL instrument also in patients with CD. It is easily completed by the patient and requires no further calculation by the investigator. SHS gives a comprehensive overview of the main aspects of the patient's subjective health perception and is a useful tool in both clinical practice and clinical studies.
