Project description:Crohn's disease (CD) patients who undergo ileocolonic resection (ICR) typically have disease recurrence at the anastomosis which has been linked with a gut dysbiosis. The aims of this study were to define the mucosa-associated microbiota at the time of ICR and to determine if microbial community structure at the time of surgery was predictive of future disease relapse. Ileal biopsies were obtained at surgery and after 6 months from CD subjects undergoing ICR. Composition and function of mucosal-associated microbiota was assessed by 16S rRNA sequencing and PICRUSt analysis. Endoscopic recurrence was assessed using the Rutgeerts score. Analysis of mucosal biopsies taken at the time of surgery showed that decreased Clostridiales together with increased Enterobacteriales predicted disease recurrence. An increase in the endospore-forming Lachnospiraceae from surgery to 6 months post-ICR was associated with remission. A ratio of 3:1 between anaerobic endospore-forming bacterial families and aerobic families within the Firmicutes phylum was predictive of maintenance of remission. Gut recolonization following ICR is facilitated by microbes which are capable of either aerobic respiration or endospore formation. The relative proportions of these species at the time of surgery may be predictive of subsequent microbial community restoration and disease recurrence.

Project description:BackgroundBudesonide is an oral glucocorticoid designed for the treatment of inflammatory bowel disease (IBD) that may reduce systemic adverse events (AEs). This review examined the efficacy and safety of budesonide for the induction and maintenance of clinical remission in Crohn's disease (CD).MethodsMEDLINE, EMBASE, other electronic databases, reference lists and conference proceedings were searched to November 2017 to identify randomized controlled trials of budesonide. Outcomes were the induction and maintenance of remission at eight weeks and one year, respectively, as well as corticosteroid-related AEs and abnormal adrenocorticotropic hormone (ACTH) tests. Pooled relative risks (RRs) and 95% confidence intervals (CIs) were estimated using random effects models.ResultsThirteen induction and 10 maintenance trials were included. Budesonide 9 mg/day was more effective than placebo (RR 1.93; 95% CI, 1.37-2.73; GRADE: moderate) but less effective than conventional steroids (RR 0.85; 95% CI, 0.75-0.97; GRADE: moderate) to induce remission. Corticosteroid-related AEs occurred less often with induction doses of budesonide than steroids (RR 0.64; 95% CI, 0.54-0.76; GRADE: moderate); budesonide did not increase AEs relative to placebo (RR 0.97; 95% CI, 0.76-1.23; GRADE: moderate). Budesonide 6 mg/day was not different from placebo for maintaining remission (RR 1.13; 95% CI, 0.94-1.35; GRADE: moderate). Both induction (GRADE: low for 3 mg/day, moderate for 9 mg/day) and maintenance budesonide treatment (GRADE: very low for 3 mg/day, low for 6 mg/day) increased the risk of an abnormal ACTH test compared with placebo, but less than conventional steroids (GRADE: very low for both induction and maintenance).ConclusionFor induction of clinical remission, budesonide was more effective than placebo, but less effective than conventional steroids. Budesonide was not effective for the maintenance of remission. Budesonide was safer than conventional steroids, but the long-term effects on the adrenal axis and bone health remain unknown.

Project description:Background & aimsCrohn's disease (CD) is a chronic gastrointestinal disease resulting from the dysfunctional interplay between genetic susceptibility, the immune system, and commensal intestinal microbiota. Emerging evidence suggests that treatment by suppression of the immune response and replacement of the microbiota through fecal microbiota transplantation (FMT) is a promising approach for the treatment of CD.MethodsWe obtained stool metagenomes from CD patients in remission and assessed gut microbiome composition before and after FMT at the species and strain levels. Longitudinal follow-up evaluation allowed us to identify the gain, loss, and strain replacement of specific species and link these events to the maintenance of remission in CD.ResultsWe found that FMT had a significant long-term effect on patient microbial compositions, although this was primarily driven by the engraftment of donor species, which remained at low abundance. Thirty-eight percent of FMT-driven changes were strain replacements, emphasizing the importance of detailed profiling methods, such as metagenomics. Several instances of long-term coexistence between donor and patient strains were also observed. Engraftment of some Actinobacteria, and engraftment or loss of Proteobacteria, were related to better disease outcomes in CD patients who received FMT, and transmission of Bacteroidetes was deleterious.ConclusionsOur results suggest clades that may be beneficial to transmit/eliminate through FMT, and provide criteria that may help identify personalized FMT donors to more effectively maintain remission in CD patients. The framework established here creates a foundation for future studies centered around the application of FMT and defined microbial communities as a therapeutic approach for treating CD.

Project description:BACKGROUND: The relapse rate after steroid induced remission in Crohn's disease is high. AIMS: To test whether oral pH modified release budesonide (3 x 1 mg/day) reduces the relapse rate and to identify patient subgroups with an increased risk of relapse. METHODS: In a multicentre, randomised, double blind study, 179 patients with steroid induced remission of Crohn's disease received either 3 x 1 mg budesonide (n = 84) or placebo (n = 95) for one year. The primary study aim was the maintenance of remission of Crohn's disease for one year. RESULTS: Patient characteristics at study entry were similar for both groups. The relapse rate was 67% (56/84) in the budesonide group and 65% (62/95) in the placebo group. The relapse curves in both groups were similar. The mean time to relapse was 93.5 days in the budesonide group and 67.0 days in the placebo group. No prognostic factors allowing prediction of an increased risk for relapse or definition of patient subgroups who derived benefit from low dose budesonide were found. Drug related side effects were mild and no different between the budesonide and the placebo group. CONCLUSION: Oral pH modified release budesonide at a dose of 3 x 1 mg/day is not effective for maintaining steroid induced remission in Crohn's disease.

Project description:BackgroundPartial enteral nutrition (PEN) may be helpful for the maintenance of remission in pediatric Crohn's disease patients.AimsTo evaluate the efficacy of PEN treatment for preventing clinical relapse.MethodsWe retrospectively assessed 42 pediatric Crohn's disease patients who entered clinical remission on 4-12 weeks of exclusive enteral nutrition (EEN) and were maintained on PEN as a supplementary diet. We evaluated the efficacy of the treatment at different time points using the weighted Pediatric Crohn Disease Activity Index (wPCDAI), Physician Global Assessment, laboratory parameters, and growth of each patient. Additionally, we assessed the use of concomitant medications.ResultsThe median length of remission with PEN was 6 (0-36) months. Patients' remission was maintained on PEN without concomitant medications for a median time of zero months (0-16). The mean body mass index in the PEN group increased from 18.1 to 18.8 after six months of PEN. The median wPCDAI decreased from 30 at diagnosis to 5.0 after EEN and increased to 7.5 after three months of PEN. Overall, the median wPCDAI decreased by 26.2.ConclusionsPEN treatment was partially effective in maintaining remission and was able to increase BMI and lower wPCDAI. Most patients required concomitant medication after PEN initiation.
