PG - e34489 LID - 10.7759/cureus.34489 [doi] LID - e34489 AB - Tumor necrosis factor-alpha (TNF-alpha) inhibitors are associated with lupus-like disease, known as anti-TNF-alpha-induced lupus (ATIL). Cytomegalovirus (CMV) was reported to exacerbate lupus in the literature. To date, systemic lupus erythematosus (SLE) triggered by adalimumab in the setting of CMV infection has never been described. We present an unusual case of a 38-year-old female with a past medical history of seronegative rheumatoid arthritis (SnRA) who developed SLE associated with the use of adalimumab and CMV infection. She had severe SLE features including lupus nephritis and cardiomyopathy. The medication was discontinued. She was initiated on pulse steroid therapy and discharged with an aggressive regimen for SLE, including prednisone, mycophenolate mofetil, and hydroxychloroquine. She remained on the medications until a year later upon follow-up. ATIL from adalimumab usually manifests only mild symptoms of SLE such as arthralgia, myalgia, and pleurisy. Nephritis is very rare, and cardiomyopathy is unprecedented. Concomitant CMV infection might contribute to disease severity. Patients with SnRA may have an increased risk of developing SLE later when exposed to such medications and infection. CI - Copyright (c) 2023, Waitayangkoon et al.
