Epidemiological data and utilization patterns of anti-TNF alpha therapy in the Hungarian ulcerative colitis population between 2012-2016.

Background: Anti-TNF therapy is efficacious in the maintenance of remission in ulcerative colitis (UC); however, long-term data on real-life use of these agents are lacking.Methods: This observational, retrospective, epidemiological study using the National Health Insurance Fund social security database aimed to understand patient characteristics and therapeutic patterns of anti-TNF therapy. Data of adult Hungarian, UC patients treated with anti-TNF agents (IFX-infliximab, ADA-adalimumab) between 2012 and 2016 were analyzed.Results: Five hundred and sixty-eight UC patients were identified. Approximately 70-80% of the patients reached maintenance therapy. A large proportion of patients stopped therapy after 10 to 12 months due to the reimbursement policy. Corticosteroid use decreased significantly after the initiation of biological therapy. The dose-escalation rate was 19.8% for ADA and 10.9% for IFX, respectively, and was performed earlier along the treatment timeline for patients on ADA. In the present study, the rate of primary non-response (PNR) was 11.6% and the rate of secondary loss of response (LOR) was 36.5%.Summary: Treatment length is in correspondence with the Hungarian reimbursement policies. The mandatory stop of treatment in the reimbursement policy is suboptimal in UC patients requiring biological therapy. The corticosteroid-sparing effect of biological therapy was demonstrated.
