. Serum erythropoietin (EPO) concentrations were markedly depressed relative to the degree of anaemia in 10 patients with acute tubular necrosis, and remained low long after restoration of excretory renal function as estimated by glomerular filtration rate. Evidence is presented that the low serum EPO level is due to defective synthesis and not to increased catabolism. It is suggested that the predominantly aregeneratory anaemia found in prolonged cases of acute tubular necrosis, and the slow restoration of red cell mass during recovery, are due to the deficient synthesis of EPO. A positive erythropoietic response in a therapeutic trial with recombinant human erythropoietin (rhEPO) appears to support this hypothesis.
