Abstract
BACKGROUND AND AIM: Ustekinumab is approved in Europe for the treatment of moderate to severe Crohn's disease (CD). Italian real-life data are scarce, so the aim of this study was to assess the effectiveness and safety of ustekinumab in an Italian cohort of CD patients. METHODS: Data of patients with CD who started using ustekinumab were extracted from the cohort of the Sicilian Network for Inflammatory Bowel Disease. Primary end-points were steroid-free clinical remission at 8, 24, and 52 weeks of therapy and reduction of C-reactive protein. Secondary end-points were treatment response, treatment persistence at 12 months, and safety. RESULTS: A total of 131 patients (males 56%; mean age 46 years ±15) were included. All patients were biologics experienced except for one. At 24 and 52 weeks, 40% and 43% of patients achieved steroid-free clinical remission, and 64% and 62% had clinical response, respectively. At the end of follow-up, there was a significant reduction of steroid use (P = 0.012) and of the Harvey-Bradshaw Index (P = 0.001). The probability of persistence in therapy with ustekinumab after 12 months of treatment was 89%. The only factor associated with discontinuation was older age. CONCLUSIONS: Data from our real-life cohort of treatment-refractory CD patients suggest the satisfactory effectiveness and safety profile of ustekinumab.
