Effectiveness and safety of a third-line rescue treatment for acute severe ulcerative colitis refractory to infliximab or ciclosporin (REASUC study).
Alimentary pharmacology & therapeutics(2024)
摘要
BACKGROUND:The advent of new therapeutic agents and the improvement of supporting care might change the management of acute severe ulcerative colitis (ASUC) and avoid colectomy.
AIMS:To evaluate the colectomy-free survival and safety of a third-line treatment in patients with ASUC refractory to intravenous steroids and who failed either infliximab or ciclosporin.
METHODS:Multicentre retrospective cohort study of patients with ASUC refractory to intravenous steroids who had failed infliximab or ciclosporin and received a third-line treatment during the same hospitalisation. Patients who stopped second-line treatment due to disease activity or adverse events (AEs) were eligible. We assessed short-term colectomy-free survival by logistic regression analysis. Kaplan-Meier curves and Cox regression models were used for long-term assessment.
RESULTS:Among 78 patients, 32 received infliximab and 46 ciclosporin as second-line rescue treatment. Third-line treatment was infliximab in 45 (58%), ciclosporin in 17 (22%), tofacitinib in 13 (17%) and ustekinumab in 3 (3.8%). Colectomy was performed in 29 patients (37%) during follow-up (median 21 weeks). Of the 78 patients, 32 and 18 were in clinical remission at, respectively, 12 and 52 weeks. At the last visit, 25 patients were still on third-line rescue treatment, while 12 had stopped it due to clinical remission. AEs were reported in 26 (33%) patients. Two patients died (2.6%), including one following colectomy.
CONCLUSION:Third-line rescue treatment avoided colectomy in over half of the patients with ASUC and may be considered a therapeutic strategy.
