Abstract

The mechanism of resistance to recombinant human erythropoietin (EPO) in hemodialysis patients with hemoglobinopathy is not yet fully understood. Poor responses to EPO have been reported in anemic dialysis patients with sickle cell disease and thalassemia. We present the first case of a hemodialysis patient with EPO resistance and hemoglobin J-Meinung, which is initially found by hemoglobin electrophoresis and finally proven by molecular genetic analysis. Additionally, the patient was diagnosed as having chronic active hemolysis with hallmarks of splenomegaly, an increased serum bilirubin and reticulocyte index, and a reduced haptoglobin level. We discuss the possible mechanisms and proper treatment options in such patients with a poor response to EPO.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
