During the pa t decade, smoking habit has been identified as a major exogenous factor in inflammatory bowel disease (IBD). It is associated not only with the development of the disease but al o with the clinical course in established disease. IBD combines absolute opposites as smoking is associated with Crohn’s disease and nonsmoking or former smoking with ulcerative colitis. The first reports of a negative association between smoking and ulcerative colitis were based on independent, clinical observations; from those studies a positive association was found between smoking and Crohn’s disease. Epidemiological studies that followed consistently showed that smokers have a reduced risk of ulcerative colitis and an increased risk of Crohn’s disease and that exsmokers have an increased risk of ulcerative colitis. In ulcerative colitis, but not in Crohn’s disease, a dose-response pattern has been demonstrated. Changes in clinical course, in disease severity and extension, and in recurrence rate indicate substantial clinical effects of smoking with a protective effect of smoking in ulcerative colitis and an aggravating effect in Crohn’s disease. There are also indications of smoking’s effects on changes in IBD epidemiology and sex distribution. The biological explanation to the finding is unknown. Smoking may aggravate Crohn’s disease by vascular effects. Theories on the protective effect in ulcerative colitis include effects on immune and inflammatory response, on mucus and on intestinal permeability. Possibly, beneficial effects in ulcerative colitis are exerted by nicotine but further studies are needed. Due to overall negative effects of smoking, IBD patients should not smoke. It seems, however, reasonable to give individual advice in patients with ulcerative colitis who have experienced a beneficial effect of ·making considering both current health status and life situation.

The incidence, prevalence, and cost of care associated with diagnosis and management of inflammatory bowel disease are on the rise. The role of gut microbiota in the causation of Crohn's disease and ulcerative colitis has not been established yet. Nevertheless, several animal models and human studies point towards the association. Targeting intestinal dysbiosis for remission induction, maintenance, and relapse prevention is an attractive treatment approach with minimal adverse effects. However, the data is still conflicting. The purpose of this article is to provide the most comprehensive and updated review on the utility of prebiotics and probiotics in the management of active Crohn’s disease and ulcerative colitis/pouchitis and their role in the remission induction, maintenance, and relapse prevention. A thorough literature review was performed on PubMed, Ovid Medline, and EMBASE using the terms “prebiotics AND ulcerative colitis”, “probiotics AND ulcerative colitis”, “prebiotics AND Crohn's disease”, “probiotics AND Crohn's disease”, “probiotics AND acute pouchitis”, “probiotics AND chronic pouchitis” and “prebiotics AND pouchitis”. Observational studies and clinical trials conducted on humans and published in the English language were included. A total of 71 clinical trials evaluating the utility of prebiotics and probiotics in the management of inflammatory bowel disease were reviewed and the findings were summarized. Most of these studies on probiotics evaluated lactobacillus, De Simone Formulation or Escherichia coli Nissle 1917 and there is some evidence supporting these agents for induction and maintenance of remission in ulcerative colitis and prevention of pouchitis relapse with minimal adverse effects. The efficacy of prebiotics such as fructooligosaccharides and Plantago ovata seeds in ulcerative colitis are inconclusive and the data regarding the utility of prebiotics in pouchitis is limited. The results of the clinical trials for remission induction and maintenance in active Crohn's disease or post-operative relapse with probiotics and prebiotics are inadequate and not very convincing. Prebiotics and probiotics are safe, effective and have great therapeutic potential. However, better designed clinical trials in the multicenter setting with a large sample and long duration of intervention are needed to identify the specific strain or combination of probiotics and prebiotics which will be more beneficial and effective in patients with inflammatory bowel disease.

Abstract Background Fatigue is a disabling symptom in patients with inflammatory bowel disease (IBD). Its prevalence, mechanism, and impact remain poorly understood. We determined changes in fatigue status over time and identified predictors of incident or resolving fatigue. Methods This was a prospective study nested within the IBD Partners cohort. Participants prospectively completed the Multidimensional Fatigue Inventory and the Functional Assessment of Chronic Illness Therapy-Fatigue at baseline, 6 months, and 12 months. A Functional Assessment of Chronic Illness Therapy-Fatigue score ≤43 defined significant fatigue. Multivariable regression models using baseline covariates were used to identify risk factors for incident fatigue at 6 months and to predict the resolution of fatigue. Results A total of 2429 patients (1605 with Crohn disease, 824 with ulcerative colitis) completed a baseline assessment, and 1057 completed a second assessment at 6 months. Persistent fatigue (at baseline and at 6 months) was the most common pattern, affecting two-thirds (65.8%) of patients. One-sixth (15.7%) of patients had fatigue at 1 timepoint, whereas fewer than one-fifth (18.5%) of patients never reported fatigue. Among patients not fatigued at baseline, 26% developed fatigue at 6 months. The strongest predictor of incident fatigue was sleep disturbance at baseline (odds ratio, 2.91; 95% confidence interval, 1.48–5.72). In contrast, only 12.3% of those with fatigue at baseline had symptom resolution by month 6. Resolution was more likely in patients with a diagnosis of ulcerative colitis, quiescent disease, and an absence of significant psychological comorbidity. Conclusions Fatigue is common in patients with IBD. However, only a few fatigued patients experience symptom resolution at 6 or 12 months, suggesting the need for novel interventions to ameliorate its impact.

AbstractIn the search for improved stool biomarkers for inflammatory bowel disease (IBD), an aptamer-based screen of 1129 stool proteins was conducted using stool samples from an IBD cohort. Here we report that of the 20 proteins subsequently validated by ELISA, stool Ferritin, Fibrinogen, Haptoglobin, Hemoglobin, Lipocalin-2, MMP-12, MMP-9, Myeloperoxidase, PGRP-S, Properdin, Resistin, Serpin A4, and TIMP-1 are significantly elevated in both ulcerative colitis (UC) and Crohn’s disease (CD) compared to controls. When tested in a longitudinal cohort of 50 UC patients at 4 time-points, fecal Fibrinogen, MMP-8, PGRP-S, and TIMP-2 show the strongest positive correlation with concurrent PUCAI and PGA scores and are superior to fecal calprotectin. Unlike fecal calprotectin, baseline stool Fibrinogen, MMP-12, PGRP-S, TIMP-1, and TIMP-2 can predict clinical remission at Week-4. Here we show that stool proteins identified using the comprehensive aptamer-based screen are superior to fecal calprotectin alone in disease monitoring and prediction in IBD.

Abstract Background and aims The COVID-19 pandemic has led to a deep reorganization of hospital services including inflammatory bowel disease (IBD) units. In this situation, conversion of in-person routine follow-up visits into phone consultations might be necessary. Here we explored the feasibility of using the validated Crohn’s Disease (CD) or Ulcerative Colitis (UC) Patient-Reported Outcomes Signs and Symptoms (CD- and UC-PRO/SS) to collect data about abdominal symptoms (abdominal/S) and bowel signs and symptoms (bowel/SS) remotely. Methods CD- and UC-PRO/SS were collected during phone consultations and compared among patients with active and inactive disease. The effectiveness of therapeutic intervention in patients with active disease was assessed by PRO/SS variation. Results Twenty-one CD and 56 UC patients were evaluated by phone. Six (28.6%) CD and 15 (26.8%) UC patients were considered to have active disease. In CD the bowel/SS but not the abdominal/S module was significantly higher in active patients (mean bowel/SS 2.50 [SE ± 0.44] active vs 0.76 [SE ± 0.18] remission, p = 0.008, AUC 0.87; mean abdominal/S 1.11 [SE ± 0.38] active vs 0.24 [SE ± 0.13] remission, p = 0.066). UC-PRO/SS measures were significantly higher in active patients as compared to patients in remission (median bowel/SS 1.63 [SE ± 0.24] active vs 0.33 [SE ± 0.04] remission; p < 0.0001, AUC 0.91; mean abdominal/S 1.03 [SE ± 0.24] vs 0.37 [SE ± 0.12]; p = 0.009, AUC 0.71). Therapy was escalated in 12 patients (3 CD and 9 UC) due to disease relapse. Therapy escalation resulted in the reduction of PRO/SS as evaluated at the subsequent phone consultation. Conclusions PRO/SS might represent a feasible tool to evaluate disease activity and therapy outcome in IBD patients during periods of limited access to outpatient clinics.

The aetiology of ulcerative colitis is unknown. Two patients without pre-existing inflammatory bowel disease in whom end colostomy for faecal incontinence was complicated by diversion colitis in the defunctioned rectosigmoid colon, are described. In both instances, colitis with the clinical, colonoscopic, and microscopic features of ulcerative colitis developed about a year later in the previously normal in-stream colon proximal to the colostomy. These cases suggest that diversion colitis may be a risk factor for ulcerative colitis in predisposed individuals and that ulcerative colitis can be triggered by anatomically discontinuous inflammation elsewhere in the large intestine.
