Their values are to be treated as a basis on which to decide on providing iron substitution. Patients with Stage 5 CKD on maintenance hemodialysis commonly suffer from malnutrition syndrome and inflammation. One of the markers for malnutrition and inflammation is low transferrin concentration. Our study focused on establishing what percentage of patients this applied to and whether or not the transferrin saturation figure was artificially inflated in such cases. Materials and Methods: The study group included 66 patients with Stage 5 CKD on maintenance hemodialysis. Such data were analyzed as complete blood count, iron and ferritin concentrations, and Transferrin Saturation (TSAT).
