Studies have demonstrated the role of TH-17 pathway in the pathogenesis of Systemic Lupus Erythematosus (SLE). Ustekinumab, a monoclonal antibody, binds and inhibits p40 subunit of IL-12 and 23, leading to IL-17 blockage, causing inhibition of TH-17 signaling pathway. Ustekinumab has rarely been used in the treatment of SLE. Herein, we discuss a patient with long standing history of Psoriasis and Psoriatic Arthritis, which was successfully being managed with anti TNF therapy. He was later diagnosed to have concomitant SLE. His persistently active and aggressive psoriatic lesions, arthritis and thrombocytopenia posed an interesting therapeutic dilemma. Fortunately his psoriatic lesions, arthritis and thrombocytopenia responded well to ustekinumab. Methotrexate was added to his regimen after improvement and he remained in remission on this therapy. Further clinical studies are warranted to investigate the role of TH-17 blocking agents in SLE.
