Abstract

Background: Patients (20%–50%) with inflammatory bowel disease (IBD) experience chronic abdominal pain during remission. The clinical features of IBD patients with abdominal pain during remission remain poorly characterized. This cross-sectional pilot study aimed to assess patient recruitment, adherence, and feedback to optimize questionnaires for future use and to determine the clinical features that distinguish IBD patients in remission with and without abdominal pain. Methods: Online validated questionnaires about disease activity, symptoms, and psychological factors were sent to participants of the UK National Institute for Health and Care Research (NIHR) IBD BioResource, which is a national research platform consisting of re-callable IBD patients designed to expedite research into Crohn's and colitis. Inclusion/exclusion criteria of the IBD BioResource main cohort were applied. Descriptive and inferential statistics were applied to participants in remission. p-values ≤0.01 were considered significant. Key results: A total of 2050 patients were approached; 291 (14.2%) of these agreed to participate. In 35 patients, technical problems, length, and poor understanding of the relevance of some questionnaires affected completion as confirmed by feedback. In total, 244 patients were full responders with 122 (50%) in remission; 33 (27%) of these had chronic abdominal pain. Comparison of those with versus without (n = 89) chronic abdominal pain yielded higher scores in patients with pain for the following: somatization (p < 0.001); gastrointestinal symptoms rating scale score (p = <0.001); highly sensitive person scale (p = 0.007); catastrophizing score (p = 0.010). Trends were observed for azathioprine use (p = 0.021); coping resources inventory health in general (p = 0.046); neuroticism (p = 0.019); and poor sleep (p = 0.03). Conclusions & inferences: Differences in symptoms and psychological characteristics exist between IBD patients in remission with and without abdominal pain. Confirmation of findings in larger studies may facilitate development of personalized chronic pain treatments for IBD patients.
