[Anemia in chronic kidney disease--reasons and treatment].

Anemia in chronic kidney disease (CKD) may affect up to 90% of the patients. It is one of the non typical risk factors of cardiovascular disease, specific for this population. The main reasons of the anemia in CKD are iron and erythropoietin deficiency. It is recognized in women with hemoglobin concentration < 11 g/dl and in men and postmenopausal women with hemoglobin concentration < 12 g/dl. Other potentially reversible reasons of anemia should be excluded in differential diagnosis. Iron and erythropoiesis stimulating agents (ESA) constitute the main treatment of anemia of CKD.
