Long-term frequent plasma exchange donation of cryoprecipitate.
Plasma exchange donation accomplishes the selective donation of cryoprecipitate. It facilitates the repeated donation of large quantities of factor VIII by individual donors and reduces donor exposure for recipients. A highly motivated donor is described who has undergone 103 donations between May 1983 and March 1987, producing 359,460 IU of factor VIII and supplying all the factor VIII needed since August 1983 by his severely affected hemophiliac son, now age 14. The donor has remained in good health, and no significant abnormalities have been noted in hematologic, biochemical, immunologic, coagulation, and serum protein testing. Extensive experience with this donor suggests that repeated plasma-exchange donation is safe and can sometimes allow single-donor support of severe hemophiliacs.
