[Serum ferritin in renal insufficiency, hemodialysis and kidney transplantation].
87 patients with end-stage renal failure on long-term hemodialysis, 25 not on dialysis and 37 with renal transplants have been studied. Serum ferritin was measured by immunoradiometric and radioimmuno-assay. The correlation between the two methods was excellent (p less than 0.001). In 25 patients on long-term hemodialysis a good correlation was found between serum ferritin levels and stainable iron (p less than 0.001). All patients with adequate iron stores had serum ferritin levels above 60 ng/ml, whereas only one out of 10 with decreased or absent iron stores had a higher leve (118 ng/ml). According to these criteria the iron stores were decreased in 59% of our patients on long-term hemodialysis, decreased or adequate in 14% and adequate or increased in 27%. There was no correlation between serum ferritin levels and serum iron and total iron binding capacity. The distribution pattern of the serum ferritin levels was log normal and did not significantly differ in the three groups studied, although the patients with renal transplants had nearly normal hemoglobin and creatinine levels. Elevated serum ferritin levels in patients (21%) on hemodialysis could only partly be explained by repeated transfusions or chronic infections.
