          Abstract

          The aim of this study was to evaluate alcohol consumption and narcotics use among patients with inflammatory bowel diseases (IBD). A comprehensive literature search was conducted in Medline using relevant keywords. The references of the retrieved articles were also searched to identify additional articles. Only English-language studies that provided evidence on alcohol consumption and/or narcotics use among non-hospitalized IBD patients were included in the present review. Twelve studies were included that examined the use of alcohol among IBD patients. The prevalence of alcohol consumption among IBD patients appeared to be similar to that of the general population. The majority of the studies reported worsening of IBD symptoms among patients who consumed alcoholic beverages. Four studies were identified that evaluated narcotics use as analgesia among IBD patients. Narcotics use was prevalent among IBD patients and correlated with a longer disease duration and comorbid mental illnesses. The available evidence suggests that alcohol consumption may have a deleterious effect on IBD symptoms. Furthermore, a considerable proportion of IBD patients are reported to use a narcotic as analgesia and this was correlated with their mental health status. Further studies are needed to address these important facets of IBD.

          Colonic microbiome is altered in alcoholism.

          Several studies indicate the importance of colonic microbiota in metabolic and inflammatory disorders and importance of diet on microbiota composition. The effects of alcohol, one of the prominent components of diet, on colonic bacterial composition is largely unknown. Mounting evidence suggests that gut-derived bacterial endotoxins are cofactors for alcohol-induced tissue injury and organ failure like alcoholic liver disease (ALD) that only occur in a subset of alcoholics. We hypothesized that chronic alcohol consumption results in alterations of the gut microbiome in a subgroup of alcoholics, and this may be responsible for the observed inflammatory state and endotoxemia in alcoholics. Thus we interrogated the mucosa-associated colonic microbiome in 48 alcoholics with and without ALD as well as 18 healthy subjects. Colonic biopsy samples from subjects were analyzed for microbiota composition using length heterogeneity PCR fingerprinting and multitag pyrosequencing. A subgroup of alcoholics have an altered colonic microbiome (dysbiosis). The alcoholics with dysbiosis had lower median abundances of Bacteroidetes and higher ones of Proteobacteria. The observed alterations appear to correlate with high levels of serum endotoxin in a subset of the samples. Network topology analysis indicated that alcohol use is correlated with decreased connectivity of the microbial network, and this alteration is seen even after an extended period of sobriety. We show that the colonic mucosa-associated bacterial microbiome is altered in a subset of alcoholics. The altered microbiota composition is persistent and correlates with endotoxemia in a subgroup of alcoholics.

            Serious Infection and Mortality in Patients With Crohn's Disease: More Than 5 Years of Follow-Up in the TREAT™ Registry

            OBJECTIVES: The objective of this study was to contribute long-term safety data for infliximab and other therapies in Crohn's disease (CD). METHODS: We prospectively evaluated CD patients enrolled in the large, observational Crohn's Therapy, Resource, Evaluation, and Assessment Tool registry, established to compare infliximab safety with conventional nonbiological medications in CD. RESULTS: A total of 6,273 patients were enrolled and evaluated on or before 23 February 2010; 3,420 received infliximab (17,712 patient-years; 89.9% received ≥2 infusions) and 2,853 received other-treatments-only (13,251 patient-years). Mean length of patient follow-up was 5.2 years. More infliximab- than other-treatments-only-treated patients had moderate-to-severe (30.6% vs. 10.7%) or severe-to-fulminant (2.5% vs. 0.6%) disease severity (P<0.001). In the year before enrollment, more infliximab- than other-treatments-only-treated patients required surgical intervention (17.4% vs. 13.6%), medical hospitalization (14.2% vs. 8.8%), prednisone (47.8% vs. 31.4%), immunomodulators (52.0% vs. 32.1%), and narcotic analgesics (17.3% vs. 9.1%). Patient mortality was similar for infliximab- and other-treatments-only-treated patients (0.58 vs. 0.59/100 patient-years). In multivariate logistic regression analyses, treatment with prednisone (hazard ratio (HR)=2.14, 95% confidence interval (CI)=1.55, 2.95; P<0.001) or narcotic analgesics (HR=1.79, 95% CI=1.29, 2.48; P<0.001) and age (HR=1.08, 95% CI=1.07, 1.09; P<0.001) were associated with increased mortality risk. Neither infliximab nor immunomodulator treatment was associated with increased mortality risk. Factors independently associated with serious infections included moderate-to-severe disease activity (HR=2.24, 95% CI=1.57, 3.19; P<0.001), narcotic analgesic treatment (HR=1.98, 95% CI=1.44, 2.73; P<0.001), prednisone therapy (HR=1.57, 95% CI=1.17, 2.10; P=0.002), and infliximab treatment (HR=1.43, 95% CI=1.11, 1.84; P=0.006). CONCLUSIONS: Mortality was similar between infliximab- and other-treatments-only-treated CD patients. An increased risk of serious infection with infliximab was observed, although CD severity and use of prednisone or narcotic analgesics carried higher risks.

              Influence of dietary factors on the clinical course of ulcerative colitis: a prospective cohort study.

              The causes of relapses of ulcerative colitis (UC) are unknown. Dietary factors have been implicated in the pathogenesis of UC. The aim of this study was to determine which dietary factors are associated with an increased risk of relapse of UC. A prospective cohort study was performed with UC patients in remission, recruited from two district general hospitals, who were followed for one year to determine the effect of habitual diet on relapse. Relapse was defined using a validated disease activity index. Nutrient intake was assessed using a food frequency questionnaire and categorised into tertiles. Adjusted odds ratios for relapse were determined using multivariate logistic regression, controlling for non-dietary factors. A total of 191 patients were recruited and 96% completed the study. Fifty two per cent of patients relapsed. Consumption of meat (odds ratio (OR) 3.2 (95% confidence intervals (CI) 1.3-7.8)), particularly red and processed meat (OR 5.19 (95% CI 2.1-12.9)), protein (OR 3.00 (95% CI 1.25-7.19)), and alcohol (OR 2.71 (95% CI 1.1-6.67)) in the top tertile of intake increased the likelihood of relapse compared with the bottom tertile of intake. High sulphur (OR 2.76 (95% CI 1.19-6.4)) or sulphate (OR 2.6 (95% CI 1.08-6.3)) intakes were also associated with relapse and may offer an explanation for the observed increased likelihood of relapse. Potentially modifiable dietary factors, such as a high meat or alcoholic beverage intake, have been identified that are associated with an increased likelihood of relapse for UC patients. Further studies are needed to determine if it is the sulphur compounds within these foods that mediates the likelihood of relapse and if reducing their intake would reduce relapse frequency.
