Abstract
BACKGROUND: Ulcerative colitis (UC) treatment is focused to achieve mucosal healing, avoiding disease progression. The study aimed to evaluate the real-world effectiveness of adalimumab (ADA) in UC and to identify predictors of remission to ADA.
METHODS: This cohort study used data from the ENEIDA registry. Clinical response, clinical remission, endoscopic remission, adverse events (AE), colectomy, and hospitalisations were evaluated; baseline characteristics and biological parameters were compared to determine predictors of response.
RESULTS: We included 263 patients (87 naïve and 176 previously exposed to anti-tumour necrosis factor alpha, TNF). After 12 weeks, clinical response, clinical remission, and endoscopic remission rates were 51, 26, and 14 %, respectively. The naïve group demonstrated better response to treatment than the anti-TNF-exposed group at short-term. Clinical and endoscopic remission within 1 year of treatment was better in the naïve group (65 vs. 49 and 50 vs. 35 %, respectively). The rates of AE, dose-escalation, hospitalisations, and colectomy during the first year were higher in anti-TNF-exposed patients (40, 43, and 27 % vs. 26, 21, and 11 %, respectively). Patients with primary failure and intolerance to the first anti-TNF and severe disease were associated with worse clinical response. Primary non-response to prior anti-TNF treatment and severe disease were predictive of poorer clinical remission. Low levels of C-reactive protein (CRP) and faecal calprotectin (FC) at baseline were predictors of clinical remission.
CONCLUSIONS: In clinical practice, ADA was effective in UC, especially in anti-TNF naïve patients. FC and CRP could be predictors of treatment effectiveness.
