Circulating Erythropoietin Levels After Bone Marrow Transplantation: Inappropriate Response to Anemia in Allogeneic Transplants
ثبت نشده
چکیده
We studied 24 recipients of autologous bone marrow transplantation (ABMT) or allogeneic BMT (BMT) to determine whether impaired erythropoietin (Epo) response to anemia could delay full erythropoietic recovery. Observed Epo levels were compared with predicted levels based on the relationship between Epo and hematocrit in 125 control subjects. Circulating Epo levels were normal during conditioning and the early posttransplant period. Between days 21 and 180, Epo levels remained normal in ABMT patients but were inappropriately low for the degree of anemia in BMT patients. Median time to full erythropoietic engraftment was

Circulating erythropoietin levels after bone marrow transplantation: inappropriate response to anemia in allogeneic transplants.

متن کاملImpaired erythropoietin response to anemia after bone marrow transplantation.
Delayed erythroid recovery is common after bone marrow transplantation (BMT), with some patients continuing to require red blood cell (RBC) transfusion support for as long as 1 year. While the etiology is multifactorial, inadequate stimulation of erythroid progenitors by the erythroid growth factor, erythropoietin, may play a role. In this study, the erythropoietin response to anemia of 70 cons...

Bone marrow transplantation (BMT) has evolved from an experimental undertaking to an established therapeutic strategy for hematological neoplasias, severe aplastic anemia, congenital immunological and metabolic disorders and some solid tumors. This report summarizes the main indications for autologous and allogenic transplants, the prerequisites and potential techniques, early and late complica...
متن کاملOptimization of recombinant human erythropoietin therapy after allogeneic hematopoietic stem cell transplantation.
OBJECTIVE Allogeneic hematopoietic stem cell transplantation (HSCT) is associated with prolonged anemia caused by defective erythropoietin (Epo) production. We enrolled 34 recipients of an allogeneic HSCT in three consecutive trials to determine the optimal utilization of recombinant human erythropoietin (rhEpo) therapy in this setting. MATERIALS AND METHODS In the first trial (n = 7), rhEpo ...
متن کاملHematopoietic stem cell transplantation in Europe 1998.
INTRODUCTION Transplantation of hematopoietic stem cells from blood or bone marrow has become accepted therapy for many diseases. Numbers of transplants have increased significantly and stem cell source, donor type and indications have changed during this decade. Information on these changes is essential for interpretation of current data, patient counseling and health care planning. PATIENTS...
