Plasma Exchange in Treatment of Leucocytoclastic Vasculitis

Plasma exchange in refractory cutaneous vasculitis

Eight patients with intractable cutaneous leucocytoclastic vasculitis were given a trial of plasma-exchange therapy. All but one improved, five substantially. Four have been successfully treated by intermittent plasma exchange for periods of 5-12 years. Apart from one episode of hepatitis B, possibly related to administration of fresh frozen plasma, no major adverse effects have occurred. Plasma exchange can be a valuable therapeutic option in patients with severe refractory cutaneous vasculitis.

Therapeutic apheresis. Applications and future directions

The past 10-15 years have been witness to major technological achievements in the field of therapeutic apheresis. Concurrently, a large number of diseases, primarily with an immunological basis, have been treated with apheresis. In this paper, we review the various applications of therapeutic apheresis, adverse reactions associated with the mode of therapy, and future research directions. Several representative diseases are also discussed in detail.
