Abstract

Available data concerning the non-hepatic source of plasma factor VIII are conflicting. In the present study, dogs with factor VIII deficiency hemophilia were transplanted with spleen or vascularized lymph node grafts obtained from normal donor dogs. Postoperative immunosuppression was done with azathioprine and heterologous antilymphocyte globulin. Four spleen transplants were successful and the recipients had positive technetium sulfide spleen scans along with adequate plasma factor VIII levels for three to eight weeks. Cessation of graft isotope uptake was accompanied by prompt disappearance of plasma factor in all four dogs. Histologically, the grafts were rejected at this time. In one dog, a second spleen graft immediately restored therapeutic factor VIII levels. Four lymph node transplants were successful and plasma factor VIII was detected for one, one, two, and ten weeks. Three dogs rejected their lymph node grafts with disappearance of factor VIII, while one had a viable transplant removed with loss of factor VIII within two days. The data suggest that factor VIII is produced in the lymphatic tissue of the dog.
