title: Inappropriate increase in erythropoietin titers during chemotherapy.
abstract: Serial erythropoietin measurements by RIA were performed in six patients with acute leukemia treated by intensive chemotherapy. In all cases erythropoietin titers increased after the onset of treatment, although the hemoglobin concentration remained at stable values. Subsequently the erythropoietin titers gradually returned to baseline levels. In same patients this reduction occurred at the end of chemotherapy, in others coincident with infections and antibiotic therapy. In four patients this decrease occurred at the time of bone marrow recovery. The explanation for this inappropriate increase in erythropoietin titers is not clear but may be related to a direct or indirect effect of a suppressed marrow on sites of erythropoietin production or catabolism.
