title: Erythropoietin deficiency in acute renal failure.
abstract: Erythropoietin (Epo) was sequentially measured by radioimmunoassay in 11 patients with acute renal failure (ARF) of varied aetiology. Epo rapidly decreased to a level inappropriately low for the haemoglobin, the reduced Epo value persisting throughout the oliguric phase and for up to 2 weeks after the restoration of apparently normal renal function. Epo values found in ARF were: at referral 18.2 +/- 9.5, mid-oliguria 14.4 +/- 6.8, diuresis 15.6 +/- 5.8, and recovery 25.1 +/- 15.8 mU/ml. Results are compared with 34 patients with end-stage chronic renal failure, 42 with non-renal anaemia, and 96 normal subjects. Epo deficiency alone is an inadequate explanation of the rapid reduction in haemoglobin at the onset of ARF, but would appear to be an important factor in the maintenance of anaemia in prolonged ARF and accounts for the slow increase in haemoglobin following recovery.
