Systematic review of infliximab-induced autoantibodies and systemic lupus erythematosus

AbstractThe present systematic review aims to discuss infliximab-induced autoantibodies and subsequent onset of systemic lupus erythematosus (SLE) through the analyses of primary reports measuring autoantibodies both before and after the administration of infliximab for the treatment of several diseases - e.g., rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and Crohn's disease. Our literature search was performed in nine databases - PubMed, Science Direct, Scopus, Web of Knowledge, Scirus, Cochrane, EMBASE, Scielo and LILACS, and the search query retrieved 998 primary reports, from which 24 articles were selected and further narrowed down to 14, based on our inclusion criteria. Two independent reviewers performed the article selection and a third reviewer solved discrepancies. Our inclusion criteria comprised primary reports of phase IV clinical trials with duration of at least three months. In total, 760 patients were evaluated and the most prevalent assays performed in the studies were anti-nuclear antibodies (ANA), anti-double stranded DNA antibodies (anti-dsDNA), and antibodies to saline-extracted antigens (ENA panel). Of all patients evaluated, 10 (1.3%) showed clinical signs and laboratorial evidence of infliximab-induced SLE
