Cyclosporin for ITP

There are patients with refractory autoimmune thrombocytopenia do not respond to standard therapy with high-dose corticosteroids, WinRHO, Rituxan, IVGG, and splenectomy. Cyclosporin is useful for some patients who occasionally respond to it. There are many published case reports of its effectiveness. It is recommended for refractory cases in standard reviews.

Since very few pateints are this refractory, prospective studies are not possible but cyclosporine is widely accepted, including being mentioned in compenida for off-label use for Evan's syndrome which is a combination of immune thrombocytopenia and hemolytic anemia.
