Prevalence of endoscopic improvement and remission according to patient-reported outcomes in ulcerative colitis.

ABSTRACT:

Background

Treatment targets for ulcerative colitis are evolving towards achievement of endoscopic improvement and remission in addition to symptom resolution. It remains to be accurately quantified what proportion of patients with symptom resolution have residual endoscopic activity that might warrant treatment modification.

Aim

To quantify the prevalence of endoscopic improvement and remission amongst ulcerative colitis patients with various permutations of patient-reported outcomes.

Methods

Individual participant data from active intervention and placebo arms of clinical trials of infliximab, golimumab, vedolizumab and tofacitinib were pooled to estimate the prevalence of endoscopic improvement (Mayo endoscopic sub-score [MES] 0 or 1) and remission (MES 0) scores with various permutations of the rectal bleeding sub-score (RBS) and stool frequency sub-score (SFS) of the Mayo score, following induction (6-8 weeks) and maintenance (30-54 weeks) therapy. Subgroup analyses were performed by year of publication and centrally read endoscopy scoring.

Results

Data from 2586 trial participants were analysed. Using locally scored endoscopy, the prevalence of endoscopic improvement and remission was highest among participants with a RBS 0 + SFS 0 post-induction (MES 0/1:81%, [95% CI 78-84]; MES 0:29% [26-33]) and during maintenance (MES 0/1:91% [87-93]; MES 0:57% [52-62]). Prevalence estimates were lower for more recently performed trials (P < .01). In comparison to locally scored endoscopy, when using central endoscopy scoring, the prevalence of endoscopic improvement and remission was lower post-induction (MES 0/1 57% [50-64], P < .001; MES 0 15% [11-21], P = .09) and during maintenance (MES 0/1 74% [67-81], P = .001; MES 0 31% [24-38], P = .001) for participants achieving a RBS 0 + SFS 0.

Conclusions

Approximately 8 of 10 patients with normalisation of rectal bleeding and stool frequency have improvement in endoscopic disease activity, whereas approximately only half of these patients have endoscopic remission.

Project description:Background & aimsLittle is known about the association between rectal bleeding and increased stool frequency with endoscopic findings in patients with mild to moderate ulcerative colitis (UC). We evaluated the associations between rectal bleeding or stool frequency and endoscopic remission in this population.MethodsWe performed a post-hoc analysis of data from a phase 3 non-inferiority trial of 817 adults with mild to moderate UC who received treatment with mesalazine. We obtained information on rectal bleeding, stool frequency, and Mayo endoscopic subscores (MESs) at weeks 0, 8, and 38. The sensitivity, specificity, and positive and negative predictive values with which rectal bleeding and stool frequency identified patients with MESs of 0 and/or 1 were calculated at weeks 8 and 38 of treatment. The associations between change in rectal bleeding and stool frequency and change in MES after treatment were quantified using the Spearman's rank correlation coefficient.ResultsAmong patients with a MES of 0, 7/82 patients (9%) had a rectal bleeding score of 1 or more and 40/82 patients (49%) had a stool frequency score of 1 or more at week 8; at week 38, 6/167 patients (4%) had a rectal bleeding score of 1 or more and 63/167 patients (38%) had a stool frequency score of 1 or more. Among patients with MESs of 0 or 1, 50/310 patients (16%) had a rectal bleeding score of 1 or more and 162/310 patients (52%) had had a stool frequency score of 1 or more at week 8; at week 38, 18/363 patients (5%) had a rectal bleeding score of 1 or more and 141/363 patients (39%) had a stool frequency score of 1 or more. The Spearman rank correlation coefficients for change in rectal bleeding and stool frequency with change in MES at week 8 were 0.39 (95% CI, 0.32-0.45) and 0.34 (95% CI, 0.27-0.40), respectively. In patients with reduced MESs at week 8, 39/389 patients (10%) had unchanged or worsening rectal bleeding and 81/389 patients (21%) had unchanged or increasing stool frequencies.ConclusionsIn a post-hoc analysis of data from a phase 3 trial of adults with mild to moderate UC treated with mesalazine, we found absence of rectal bleeding to identify patients in endoscopic remission. However, many patients in remission still have increased stool frequency, indicating that it may not be a sensitive marker of disease activity in patients with mild to moderate UC.
