Background

Medical therapy for inflammatory bowel disease (IBD) should have dual goals of improving symptoms and mucosal healing. Patient-reported outcomes (PROs) used for approval of ulcerative colitis (UC) treatments include number of bowel movements and bloody stools.[1] Recent research highlights the discordance between PROs and mucosal healing.[2] The aim of this analysis is to understand patient perspectives on UC symptoms and disease burden based on a cross-sectional survey of UC patients. We hypothesised that UC patients experience disease activity despite treatment and that current PROs fail to capture the full impact of disease activity on patients’ lives.

Methods

The IBD In America survey recruited patients via InflammatoryBowelDisease.net and associated social platforms in 2019. Patients self-reported an IBD diagnosis, were 18+, lived in U.S., and participated without monetary incentive. Survey questions addressed diagnosis, symptoms, QoL, treatment, demographics, etc. Survey terms were based on how patients discuss UC in the IBD online community. Remission was defined as ‘significant reduction of symptoms without an actual cure.’ Flare was defined as ‘temporary intensification of symptoms.’ Patients were categorised by disease activity based on number of flares and remission status during the past year.

Results

Of 487 patients diagnosed with UC, mean age was 45.6 (SD 16.0); 85% were female; 89% moderate to severe; 78% diagnosed in past 5 years; and 51% taking 5ASAs, 37% biologics/JAKs, and 23% immunomodulators. Despite treatment, 46% experienced 15+ symptom days in the past month. Fatigue/low energy was most frequent complaint (86%) followed by urgency to move bowels (80%), abdominal pain/cramps (76%), joint pain/inflammation (67%), and bloating (66%). Daily pain was experienced by 32%; even patients in remission with no flares experienced pain at least once a month (55%). Difficulty completing daily tasks was reported by 37%, and 27% felt their UC was not controlled despite efforts to manage it. Only 7% reported being in remission with no flares (past year) and no symptoms (past month).

Conclusion

Most UC patients experience frequent symptoms and flares while on treatment. The most common and bothersome symptoms are not taken into account in PROs nor addressed with current treatment. A more holistic approach to patient disease is needed.
