The mechanisms of erythrocyte recovery after BMT are not known. We investigated the respective role of marrow function and erythropoietin production in 31 ABMT and 47 allogeneic BMT by analysing peripheral counts, serum erythropoietin levels, and serum transferrin receptor (TfR) levels which have been shown to be a quantitative measurement of erythropoiesis. Median times to complete neutrophil (25 vs 48 days, p < 0.0001) and platelet (45 vs 263 days, p < 0.001) recovery were faster after allogeneic BMT than ABMT, but complete erythrocyte recovery was slower (218 vs 101 days, p < 0.001). After ABMT, erythrocyte recovery paralleled that of neutrophils and platelets, and erythropoietin levels remained appropriate for the degree of anemia. After allogeneic BMT, erythrocytes developed independently of the other cell lines and defective erythropoietin production delayed recovery of adequate erythropoietic activity. This correlated with an alteration of renal function only in those patients remaining erythropoietin deficient beyond day 180. However, supranormal erythropoietin levels in interstitial pneumonia suggests that erythropoietin response to hypoxia is not abrogated. CMV infection could also affect erythropoiesis through erythropoietin production after ABMT as well as allogeneic BMT. It is concluded that after ABMT the development of erythropoiesis is determined by the overall marrow proliferative activity and erythropoietin plays only a facilitating role. After allogeneic BMT, erythropoiesis depends on erythropoietin levels which remain inadequate for prolonged periods of time. The results suggest that the administration of recombinant human erythropoietin could reduce transfusion requirements after BMT.
