INTRODUCTION: Despite advances in Ulcerative Colitis (UC) therapies, many patients suffer refractory defecatory symptoms in the absence of active inflammation. For this group, treatment is challenging, with a paucity of research and limited therapeutic options. In this prospective, ongoing study, we aim to determine the prevalence of faecal incontinence (FI) in patients with quiescent UC. METHODS: In a cross-sectional study, consecutive patients with UC attending Inflammatory Bowel Disease (IBD) clinics completed a series of validated questionnaires; including an IBD-specific FI questionnaire (ICIQ-IBD questionnaire), Hospital Anxiety and Depression Scale (HADS), the Rome IV diagnostic questionnaire, and the IBD-control questionnaire. Participants were requested to return a Faecal Calprotectin (FCP) within 2 weeks of completing questionnaires. Quiescent UC was defined as IBD-control 8 score ≥13 and IBD-control-VAS ≥85, and/or FCP levels ≤250 (where available, FCP data were used in preference to IBD-control to classify UC activity). Data were compared between active and quiescent groups using chi-square and non-parametric tests. RESULTS: Overall, n = 97 UC patients (n = 50 males, mean age 48 (range 18-82) participated. ICIQ-IBD data revealed that most patients experience FI (84/97 (87%) during 'relapses'. Interestingly, 58/97 (60%) reported FI when in 'remission', and this group had higher median HADS depression (P = 0.0002), poorer QoL scores (P < 0.0001), and trend towards higher HADS anxiety (P = 0.09) scores, compared to those without FI. Disease activity data (IBD-control and/or FCP) were available for all patients, and based on these 61/97 (63%) had quiescent UC. The prevalence of FI based on ICIQ-IBD did not differ between those with active (22/36, 61%) and quiescent UC (36/61, 59%), P = NS. In those with FI on ICIQ-IBD, median IBD-FI symptom scores, IBD-FI QoL scores and HADS (anxiety: P = 0.47, depression: P = 0.18) id not differ between disease activity groups. However, within the quiescent group, patients that met the more stringent Rome IV criteria for FI (n = 13) had higher median IBD-FI symptom scores (P = 0.007) and HADS-depression scores (P = 0.05), a trend to worse IBD-FI QoL (P = 0.07), but similar HADS-anxiety (P = 0.68). CONCLUSION: This is one of the first studies to identify that FI affects most patients with UC, regardless of disease activity, with a detrimental impact on patients' psychological wellbeing and QoL. FI be screened for in IBD clinics. There is an urgent need for further research in this area.
