Abstract
A prospective study was begun in January 1975 to evaluate the effect of splenectomy on graft and patient survival in recipients of first cadaver kidney transplants. Ninety-two cases were evaluated. Splenectomy increased the survival of both grafts and recipients. The benefit from splenectomy compensated readily for the perioperative morbidity of splenectomy and the long-term increased risk of sepsis from certain bacteria for the asplenic patient. Splenectomy exerted its effect by reducing the incidence and intensity of rejection episodes. It was not clear whether the observation resulted from a direct immunosuppressive effect of splenectomy or from the increased tolerance to azathioprine observed in asplenic recipients. Finally, splenectomy negated an effect of race that had been observed earlier for survival of cadaver transplants and recipients.
