Polycythemia after kidney transplantation: influence of the native kidneys on the production of hemoglobin.

3 patients with renal transplantation who developed polycythemia presented normalization of the hemoglobin levels immediately after nephrectomy of the native kidneys. This observation induced the authors to study the role of the native kidneys in the genesis of polycythemia in recipients of renal allografts. Comparison was made among 32 patients submitted to renal transplantation, with maintenance of native kidneys (group I) and among 31 under the same conditions, but without the native kidneys (group II). Both groups were comparable according to age, sex, rejection crisis incidence and immunosuppressive therapy. It was observed that the hemoglobin levels of group I were significantly higher (p less than 0.05 to p less than 0.005) than those observed in group II, from the 3rd to the 30th posttransplantation month, becoming comparable from the 36th to the 54th months. The hemoglobin production, measured by the kinetics of labeled iron (59Fe), was higher in patients of group I. The authors concluded that the native kidneys are responsible for the observed polycythemia after a kidney transplantation.

Studies on erythropoiesis in patients with renal failure and after kidney transplantation.

Ferrokinetic studies were made in 16 patients before and after kidney transplantation. The Fe clearance decreased in 9 of 11 patients, the plasma iron turnover showed no variation in six patients, while it increased in three and decreased in one, the production of hemoglobin increased significantly after transplantation. The nonnephrectomized patients showed more erythropoiesis after transplantation, manifested by higher hemoglobin level, shorter Fe clearance, and lower serum iron. Uremic patients, including the anephric, had significant responses in erythropoiesis both to stimulation by phlebotomy and to inhibition by blood transfusion. After transplantation, however, the response to phlebotomy was greater and the blockade by blood transfusion smaller, than during uremia.
