Tocilizumab treatment in a patient suffering from rheumatoid arthritis and concomitant chronic hepatitis C infection

Abstract
Sir, Immunosuppressive therapy with biologics in patients with RA and concomitant infection with HCV is a challenge in clinical practice. Tocilizumab (TCZ) is a humanized mAb directed towards the IL-6 receptor that has become a novel treatment option for RA. Here we report on an RA patient with chronic HCV infection who received TCZ during an 12-month follow-up period.
