 From these results, cytapheresis can be considered a safe and effective treatment for MPO-ANCA-associated vasculitis. As for the mechanism of its action, soluble tumor necrosis factor receptor 1 (sTNFR), sTNFR2 and interleukin 1 receptor antagonist were elevated soon after cytapheresis and those levels 2 h after the cytapheresis procedure were higher than before the procedure in some cases. These elevations might be related to the efficacy of cytapheresis.
