BACKGROUND: Health-related quality of life [HRQoL] is impaired in ulcerative colitis and is correlated to clinical disease activity. The recent shift towards more objective treatment goals like mucosal healing generates a need for evaluating the association between endoscopic disease activity, mucosal healing and HRQoL.

METHODS: In this cross-sectional study, patients with either active or inactive ulcerative colitis underwent sigmoidoscopy. Clinical disease activity was assessed by the Simple Clinical Colitis Activity Index [SCCAI], endoscopic inflammation by the Mayo Endoscopic Subscore [MES], and HRQoL by the Short Inflammatory Bowel Disease Questionnaire [SIBDQ] and Short Health Scale [SHS].

RESULTS: A total of 110 patients, 71% with active disease, had a median SCCAI score of 3 and a median MES score of 1. Patients in clinical remission had a mean SIBDQ of 60 and SHS of 6. HRQoL decreased significantly with increasing clinical (SIBDQ [χ(2) = 61.8, p < 0.0001] and SHS [χ(2) = 63.4, p < 0.0001]) and endoscopic disease activity (SIBDQ [χ(2) = 33.1, p < 0.0001] and SHS [χ(2) = 40.3, p < 0.0001]). Mucosal healing was associated with a higher HRQoL than active inflammation (59/46, p < 0.0001 [SIBDQ] and 7/20, p < 0.0001 [SHS]). Decreased HRQoL was observed with more extensive disease. Linear regression revealed strong association between SIBDQ and SHS.

CONCLUSIONS: Not only clinical disease activity but also endoscopic inflammation and disease extent were associated with decreased HRQoL. Patients with mucosal healing had significant higher HRQoL, emphasising the importance of this treatment goal. Both SHS and SIBDQ are easy to use and to implement, and were strongly correlated.
