Deficient erythropoiesis
WebSideroblastic anemias are a diverse group of anemias characterized by the presence of increased serum iron, ferritin, and transferrin saturation as well as ringed sideroblasts (erythroblasts with perinuclear iron-engorged mitochondria). Symptoms are those of anemia and include fatigue and lethargy. Diagnosis is with complete blood count ... WebErythropoiesis-stimulating agents (ESAs) (e.g. erythropoietin or epoetin), are genetically engineered erythropoietin recombinants that were introduced in the late 1980s for anemia management in patients undergoing hemodialysis. Beginning in the early 1990s ESAs have been used for chemotherapy-induced anemia.

WebThe ZPP/H ratio is highly specific for iron-deficient erythropoiesis. However, it does not distinguish between absolute iron deficiency and iron-deficient erythropoiesis caused by anemia of chronic disease (ACD). Thus, a positive test result of ZPP/H should be followed by a serum ferritin determination to distinguish iron deficiency from iron ... WebAnemia, a decrease in the number of red blood cells (RBCs), hemoglobin (Hb) content, or hematocrit (Hct), can result from decreased RBC production (erythropoiesis), increased RBC destruction, blood loss, or a combination of these factors.
