Recurrent thrombotic microangiopathy in a renal allograft. Case report and review of the literature.
Thrombotic microangiopathy in a renal allograft may either reflect a recurrence of the patient's original disease, i.e., thrombotic thrombocytopenic purpura, hemolytic-uremic syndrome, or more commonly may be a manifestation of allograft rejection. This report describes a patient in whom irreversible renal failure developed during thrombotic thrombocytopenic purpura. Two years later while her condition was in clinical remission, she received a 2 DR-matched cadaveric allograft. Nineteen days following transplantation, thrombotic microangiopathy developed in the graft with eventual loss of allograft function despite vigorous plasmapheresis therapy. Multiple factors in addition to possible recurrent disease that may have contributed to this event were identified. The literature on thrombotic microangiopathy and renal transplantation is reviewed.
