To describe our clinical experience in treating refractory PAN with infliximab (a TNF inhibitor), a drug with good tolerability and better safety profile than cyclophosphamide.
We measured both serum anti-phosphatidylserine-prothrombin complex (anti-PSPT) antibodies and anti-moesin antibodies, as well as various cytokines (interleukin [IL]-2, IL-4, IL-5, IL-10, IL-13, IL-17, granulocyte macrophage colony-stimulating factor, γ-interferon, tumor necrosis factor-α) levels in polyarteritis nodosa (PAN) patients with cutaneous manifestations.
