BACKGROUND: Head-to-head comparison studies evaluating the effectiveness and tolerability of anti-tumor necrosis factor (anti-TNF) drugs in inflammatory bowel disease patients are lacking. AIM: To compare the effectiveness and tolerability of anti-TNF-α drugs used in clinical practice in a cohort of patients with moderate-to-severe ulcerative colitis (UC). METHODS: Retrospectively, 122 UC patients treated with infliximab (IFX) originator and biosimilar, adalimumab (ADA), and golimumab (GOL) were included. We performed an ITT analysis to evaluate clinical response and remission, steroid-free clinical remission, and endoscopy response according to the different time points of the follow-up. Baseline and post induction predictor factors of these outcomes were evaluated using multivariate logistic regression models. Moreover, a propensity score-based weighting analysis was performed. Data were analyzed using R and STATA11 software. RESULTS: The overall clinical response was 77% after induction, 81.4% at 30 weeks, and 76.9% at 52 weeks, while the steroid-free clinical remission was 39.7, 46, and 54.6%, respectively. After induction, a higher rate of treatment failure was observed in the GOL group. At the end of follow-up, lower rates of steroid-free clinical remission and clinical response were obtained by GOL. At week 52, endoscopic response was achieved by 46.5% of the population. CONCLUSIONS: Among the different anti-TNF treatments, moderate-to-severe UC seems to respond better to IFX and ADA, whereas GOL seems to be less effective, despite a similar good safety profile.
