Risk of Reactivation of Hepatitis B Virus Infection in Psoriasis Patients Treated With Biologics: A Retrospective Analysis of 20 Cases From the BIOBADADERM Database
Abstract
A 5% risk of reactivation of hepatitis B virus (HBV) infection has been reported in patients with diseases other than psoriasis treated with tumor necrosis factor inhibitors. The aim of this study was to investigate the risk of HBV reactivation in patients with a past history of HBV infection who were receiving biologic therapy for psoriasis. This was a multicenter study of 20 patients with psoriasis who were treated with at least 1 biologic agent. All the patients had serologic evidence of past HBV infection (positive total hepatitis B core antibody and negative hepatitis B surface antibody). We analyzed the clinical, serological, and liver function variables recorded before, during, and at the end of follow-up. The viral load at the end of follow-up was also analyzed for all patients. None of the patients fulfilled the criteria for HBV reactivation at the end of a median follow-up period of 40 months. Combining our data with data from other studies of psoriasis patients with a past history of HBV infection who were treated with a biologic, we calculated a maximum estimated risk of HBV reactivation for a mean follow-up period of 30 months of 2.7 reactivations per 100 patients. Biologic therapy did not cause HBV reactivation in...Continue Reading
