Abstract
This study was constructed to investigate the relationship between renal anaemia and erythropoietin (EPO) concentrations in chronic renal failure (CRF) patients and to evaluate the possible role of the liver. Serum EPO levels were measured in blood samples from 20 CRF patients on hemodialysis (HD), 20 liver cirrhosis (LC) patients, 20 patients having both CRF and LC and undergoing HD, and 20 normal control subjects. Blood cell counts, iron indices (iron, total iron-binding capacity (TIBC) and ferritin), renal function (blood urea nitrogen (BUN) and creatinine), hepatic function (ALT, AST, ALP and bilirubin) investigations were carried out for all the subjects enrolled in this study. CRF patients without LC had serum EPO concentration of 6.21 ± 0.53 mU/ml (mean ± SE), which was significantly higher than that in patients having both CRF and LC (4.32 ± 0.52) (p < 0.01). Both groups showed significantly lower values than the controls (12.75 ± 0.70) (p < 0.001). LC patients with intact kidneys had significantly higher EPO level (22.70 ± 1.70) (p < 0.001). No correlation was found between EPO level and any of the hematologic or iron indices.
