Abstract:
Infliximab (IFX) is an anti-tumor necrosis factor (TNF) monoclonal antibody used to treat rheumatoid arthritis, ankylosing spondylitis, and Crohn's disease. Rarely, anti-TNF-induced lupus (ATIL) may occur. ATIL differs from classical drug-induced lupus. We report a 49-year-old woman who developed polyarthralgia after 2 years of IFX treatment for Crohn's disease. Based on the autoantibody profiles, ATIL was diagnosed and low-dose glucocorticoid, hydroxychloroquine, and celecoxib were prescribed. However, arthralgia and hemolytic anemia developed. Because the anti-dsDNA titers waxed and waned, she was switched to vedolizumab, a monoclonal antibody to the human lymphocyte α4β7 integrin. Six months after switching treatment, the arthralgia had improved and the anti-dsDNA antibody normalized. Here, we report a case of ATIL that resolved after switching from infliximab to vedolizumab.
