Impact of Endoscopic and Histologic Activity on Disease Relapse in Ulcerative Colitis.

INTRODUCTION: Endoscopic healing is currently considered the main target in the management of ulcerative colitis (UC). There are conflicting data about the role of histology as a stricter treatment objective. We aim at evaluating the additional benefit of histologic remission over endoscopic remission. METHODS: We performed a prospective observational study at the McGill University Health Center. We enrolled adult patients with UC in clinical remission for at least 3 months undergoing a colonoscopy. Endoscopic disease activity was based on the Mayo endoscopic score. Rectal biopsies were obtained, and the histologic activity was evaluated using the Geboes score (active disease defined as Geboes score ≥ 3.1) with the addition of assessing the presence of basal plasmacytosis. Patients were followed up for 12 months for disease relapse defined as a partial Mayo score of > 2. At the time of relapse or end of follow-up, all patients underwent repeat endoscopic evaluation. The primary end point was clinical relapse. RESULTS: Two hundred fifty-three patients were included. The presence of basal plasmacytosis was associated with relapse (adjusted odd ratio = 2.07, 95% confidence interval [CI] 1.06-4.18, P = 0.042). Time to clinical relapse was significantly higher for patients with Mayo endoscopic score > 0 with adjusted hazard ratio = 2.65, 95% CI 1.31-5.39, and P = 0.007. Time to clinical relapse was not significantly higher for Geboes score ≥ 3.1 with adjusted hazard ratio = 1.29, 95% CI 0.67-2.49, and P = 0.45. DISCUSSION: Active histologic disease did not affect time to clinical relapse in patients with UC who achieved endoscopic remission while the presence of basal plasmacytosis is associated with relapse.

Maladaptive coping, low self-efficacy and disease activity are associated with poorer patient-reported outcomes in inflammatory bowel disease.

BACKGROUND/AIMS: Patient-reported outcomes (PRO) are key aspects in the management of inflammatory bowel disease (IBD). This study aims to evaluate factors associated with adverse PRO, including modifiable social constructs of maladaptive coping and self-efficacy as well as physician-patient concordance on PRO. PATIENTS AND METHODS: This cross-sectional study was performed in patients with Crohn's disease (CD) or ulcerative colitis (UC) from September 2015 to March 2016. Validated questionnaires were used to assess quality of life (Short IBD Questionnaire), disability (IBD disability index), productivity (work productivity and activity impairment questionnaire), anxiety/depression (Hospital Anxiety and Depression Scale), coping strategies [Brief Coping Operations Preference Enquiry (Brief COPE)], and self-efficacy (General Self-Efficacy Scale). Independent physician assessment was used to compare concordance with patients. RESULTS: In all, 207 (CD: 144 and UC: 63) patients, with median age of 39 years, were included, with 42.5% males. Significant proportion of patients reported moderate/severe impairment of disability (30.5%), quality of life (29.4%), productivity (52.4%), anxiety (32.9%) and depression (23.3%). Disease activity and maladaptive coping were independently associated with unfavourable PRO, whereas self-efficacy had a positive effect in multivariate analysis. Physicians could accurately identify the magnitude of PRO impairment in standard clinical settings (r = 0.59-0.65, P < 0.001). CONCLUSION: Disease activity and modifiable psychological constructs are associated with unfavorable PRO in patients with IBD. These factors could assist with identifying high-risk patients, many of whom may benefit from targeted interventions to improve health outcomes.

Screening for Nonalcoholic Fatty Liver Disease in Inflammatory Bowel Diseases: A Cohort Study Using Transient Elastography.

Background: Inflammatory bowel disease (IBD) patients may be at risk for nonalcoholic fatty liver disease (NAFLD) due to chronic inflammation, hepatotoxic drugs, and alteration of the gut microbiota. Prospective data using accurate diagnostic methods are lacking. Methods: We prospectively investigated prevalence and predictors of NAFLD and liver fibrosis by transient elastography (TE) with associated controlled attenuation parameter (CAP) in IBD patients as part of a routine screening program. NAFLD was defined as CAP ≥248 dB/m. Significant liver fibrosis (stage 2 or higher out of 4) was defined as TE measurement ≥7.0 kPa. Predictors of NAFLD and significant liver fibrosis were determined by logistic regression analysis. Results: A total of 384 patients (mean age 42.4 years, 45.0% male, 64.6% with Crohn's disease) with no significant alcohol intake were included. Prevalence of NAFLD and significant liver fibrosis was 32.8% and 12.2%, respectively. Independent predictors of NAFLD were older age (adjusted odds ratio [aOR], 1.45; 95% confidence interval [CI], 1.15-1.82), higher body mass index (BMI; aOR, 1.31; 95% CI, 1.20-1.42) and higher triglycerides (aOR, 1.45; 95% CI, 1.01-2.09). Significant liver fibrosis was independently predicted by older age (aOR, 1.38; 95% CI, 1.12-1.64) and higher BMI (aOR, 1.14; 95% CI, 1.07-1.23). Extrahepatic diseases were more common in IBD patients with NAFLD compared with those without, namely chronic kidney disease (10.3 vs 2.3%; P < 0.001) and cardiovascular diseases (11.3 vs 4.7%; P = 0.02). Conclusions: NAFLD diagnosed by TE with CAP is a frequent comorbidity in IBD patients and is associated with extrahepatic diseases. Noninvasive screening strategies could help early diagnosis and initiation of interventions, including weight loss, correction of dyslipidemia, and linkage to care. 10.1093/ibd/izy200_video1izy200.video15794817619001.

Motor vehicle collisions and their demographics: a 5-year retrospective study of the Hamilton-Wentworth Niagara region.

This retrospective study examined population demographics associated with motor vehicle collision (MVC) fatalities over a 5-year period in the Hamilton-Wentworth Niagara region. Variables were drawn from the five factors proposed by Fierro (1) for investigating deaths caused by transportation: human, chemical, environmental, vehicular, and highway. Factors analyzed included age, gender, position to the vehicle, site(s) of injury, toxicology, environmental contributors, and vehicular findings. From 1999 to 2004, there were 321 MVC fatalities that primarily involved males 20 to 29 years of age and commonly drivers or pedestrians. Cars and trucks were the most frequent vehicles. Fatalities occurred most often on local and regional roads on Fridays and Sundays between 6 pm and 6 am. Mechanical failure and weather conditions were not significant contributors. Toxicological analyses (275/321) were performed on the majority of the study population. Ethanol was present in isolation and with other substances, especially cannabis, mostly in male drivers 20-59 years of age.
