Lupus Unmasked: The Infliximab Connection

Drug-induced lupus erythematosus (DILE) is an autoimmune phenomenon where the symptoms are similar to systemic lupus erythematosus (SLE) after exposure to certain drugs. While DILE tends to be less severe than SLE, the diagnosis can be challenging. Infliximab, a TNF-alpha inhibitor, is widely prescribed for autoimmune conditions such as Crohn’s disease, rheumatoid arthritis, and ankylosing spondylitis. Although rare, Infliximab can cause Drug-Induced Lupus Erythematosus (DILE). This case report presents a 67-year-old male patient who developed this unconventional adverse drug reaction. It emphasizes the importance of vigilant monitoring, early detection, and prompt intervention to prevent long-term complications in patients receiving Infliximab treatment.
