Remission of acquired pure red cell aplasia following plasma exchanges:

Abstract

A 22-year-old woman had an idiopathic pure red cell aplasia that failed to respond to high doses of corticosteroids. After a series of 10 plasma exchange procedures, bone marrow erythropoiesis and reticulocyte blood count returned to normal; the haematological remission has been now persistent for 12 months. The place of plasma exchange in the management of pure red cell aplasia and its mode of action will be discussed.
