Mycobacterium abscessus pulmonary infection under treatment with tocilizumab

Abstract

Although biological agents are of considerable benefit to patients with rheumatoid arthritis (RA), the potential for opportunistic infections is a critical issue. It is therefore important to achieve a balance between treatment efficacy and controlling opportunistic infection. We herein report the successfully managed case of a 53-year-old patient with RA who developed pulmonary Mycobacterium abscessus infection during treatment with tocilizumab and methotrexate.
