Natural history and impact of irritable bowel syndrome‐type symptoms in inflammatory bowel disease during 12 months of longitudinal follow‐up

Abstract

AbstractBackgroundLittle is known about the natural history and impact of irritable bowel syndrome (IBS)‐type symptoms on psychological health and quality of life in inflammatory bowel disease (IBD). We aimed to address this in a 12‐month longitudinal follow‐up study of secondary care patients.MethodsWe collected demographic, Rome III IBS‐type symptom, psychological, and quality of life data, with questionnaires at 3‐month intervals, over 12 months of follow‐up in patients with IBD in clinical remission at baseline. We assessed the natural history of Rome III IBS‐type symptoms over the 12 months of the study and compared psychological and quality of life data between those reporting Rome III IBS‐type symptoms at each of the points of follow‐up with those not reporting such symptoms.Key ResultsAmong 206 patients with IBD in clinical remission at baseline (104 [50.5%] women, mean age 56.9 years [range 18–83 years], 79 [38.3%] Crohn's disease), 33 (16.0%) reported Rome III IBS‐type symptoms at baseline and 72 (35.0%) reported Rome III IBS‐type symptoms at one or more time points. Among the 33 patients with Rome III IBS‐type symptoms at baseline, symptoms resolved in 6 (18.2%) patients, were present throughout in 6 (18.2%) patients, and fluctuated in the remaining 21 (63.6%) patients. Among the 39 patients with new onset of Rome III IBS‐type symptoms after baseline, 24 (65.1%) had symptoms at one point in time only, 10 (25.6%) at two points, four (10.3%) at three points, and one (2.6%) at four points. At each point in time, reporting IBS‐type symptoms was associated with significantly higher anxiety, depression, or somatoform symptom‐reporting scores, and/or lower quality of life scores.Conclusions & InferencesIn this 12‐month follow‐up study, one‐third of patients with IBD reported presence of Rome III IBS‐type symptoms at any point in time. Reporting such symptoms was associated with significant impacts on psychological health and/or quality of life.
