title: Erythrocyte ferritin in patients on chronic hemodialysis treatment.
abstract: Serum ferritin (SF) and erythrocyte ferritin (EF) were evaluated in 35 patients on chronic hemodialysis treatment (CHD), in 45 healthy subjects and in 22 nonnephropathic females with iron deficiency anemia. Twenty-five CHD patients with basal SF less than 500 micrograms/l were treated orally with 200 mg of Fe2+ for 2 months and the positive (hemoglobin increase greater than 1 g/dl) or negative response to the therapy was correlated to the basal levels of SF and EF. Three groups of CHD patients could be defined on the basis of their basal SF levels (hypo-, normo- or hyperferritinemic). Nine patients with increased SF levels had also EF levels significantly higher than the other CHD patients and controls since they were probably iron-overloaded. In the other 2 groups of CHD patients, EF levels were significantly higher than in controls for each level of SF probably because of the reduced utilization of iron by uremic bone marrow. Among the 25 treated CHD patients, only 5 responded to the therapy: 3 were hypoferritinemic while the other 2 responders had basal SF within the normal range. Four hypoferritinemic patients did not respond to the therapy. Four out of five responders had the lowest EF levels among CHD patients. EF measurement could be an important and useful test in detecting the presence of an iron deficiency erythropoiesis in CHD patients.
