Successful treatment of acute humoral rejection in a heart transplant patient.

Abstract

Eight months after undergoing orthotopic heart transplantation, a patient had hypotension and biventricular heart failure. Endomyocardial biopsy specimens showed a modest cellular infiltrate, predominantly of plasma cells, and progressive myocyte injury, suggesting a humoral rejection process. The patient was treated with Minnesota antilymphoblast globulin and aggressively with plasmapheresis, resulting in evidence of myocyte repair, improved hemodynamics, and long-term survival.
