The Potential of Telitacicept in Treating Lupus erythematosus panniculitis: A Case Report.

Lupus erythematosus panniculitis (LEP) is a rare and serious skin lesion associated with systemic lupus erythematosus (SLE). In the past, the management of LEP has followed the treatment guidelines for SLE, which is based on the administration of high doses of hormones together with immunosuppressants, with no treatment plans specific for LEP. However, the long-term use of high hormone doses and immunosuppressants can exacerbate skin breakage and calcification. Telitacicep is an approved biological agent demonstrating significant therapeutic efficacy in immune system disorders. We report a case of lupus erythematosus panniculitis in which the patient's clinical symptoms and laboratory test results improved after treatment with a combination of steroids, cyclophosphamide, and the biologic agent Telitacicept. The condition was significantly controlled and alleviated. This report highlights the successful application of Telitacicept in the treatment of lupus panniculitis, providing valuable insights for future management of this condition.
