Erythropoiesis has been examined in relation to kidney function in 38 patients during the 3-month period following successful renal transplantation, using serial determinations of erythropoietin, haemoglobin, and creatinine. Two peaks of serum erythropoietin were observed: an early peak that occurred within 2 days of transplantation and was observed in ten patients, and a late one between 8 and 30 days, observed in 28 patients. The early peak did not produce an increase in haemoglobin and occurred only in the presence of delayed onset of graft excretory function when serum creatinine was greater than 1000 µmol/l. The ineffectiveness of the early peak may be due to the uraemic environment, which is probably a sequel of the tubular damage associated with postoperative acute tubular necrosis. The late peak followed a decrease in serum creatinine to less than 200 µmol/l and was associated with an increase in haemoglobin of 34 g/dl during the next 26 weeks.
