Efficacy of anti-TNF therapy for the treatment of patients with moderate-to-severe inflammatory bowel disease; A first Iranian report

BACKGROUND The anti-TNF drugs are shown to be highly effective in treatment of patients with moderate-to-severe inflammatory bowel disease (IBD). Here, we aimed to assess the efficacy and safety of anti-TNF therapy at the national level. METHODS IBD patients aged 15 > years who received Infliximab and/or CinnoRA® between 2013 to July 2018 were identified. The data extracted from medical dossier and telephonic interview. The efficacy of therapy was defined as time to drug discontinuation or need for IBD-related surgery. The safety was assessed based on patient�s reported adverse events. RESULTS We included 315 patients. The mean age of patients was 37.2 years and 62.2 of them developed the disease before age 30 years. Involvement of masculoskeletal system was reported in 7.3 of patients. Partial and complete response to Anti-TNF therapy was seen in 67 of patients. About 16 of patients did not respond to induction therapy and 16.9 of patients lost their response to Anti-TNF during one year. No serious adverse events, serious opportunistic infection, tuberculosis and malignancies reported by patients. Two patients reported pneumonia. CONCLUSION This study for the first time in our country, provides the evidences for efficacy of anti-TNF therapy in moderate to severe IBD patients. © 2020 The Author(s)
