Chronic kidney disease (CKD) is a global socially significant health problem affecting more than 10% of the world's population. One of the complications of CKD is the anemic syndrome, which is associated with reduced quality of life, increased morbidity and mortality and higher treatment costs. A common condition in the treatment of anemia in patients with CKD is erythropoietin resistance. It is one of the most powerful predictors of the risk of cardiovascular accidents and mortality. The aim of the present study was to analyze some of the major factors leading to the development of erythropoietin resistance. In 50 patients undergoing regular hemodialysis treatment at the Clinic of Nephrology of the St. Marina University Hospital, Varna were studied demographic indicators, levels of serum iron, TIBC, TSAT (transferrin saturation), URR, ERI, CRP and iPTH.
