Serum ferritin in haemodialysis patients: is there a relationship to 'haemochromatosis alleles' HLA A3, B7, B14?

Serum ferritin levels were measured in 57 patients on maintenance haemodialysis to determine if patients who possessed 1 or more of the histocompatibility antigens associated with idiopathic haemochromatosis (HLA A3, B7 or B14) were at increased risk of iron overload. There was no significant difference in the mean serum ferritin levels between those patients with HLA A3, B7 or B14 (357.9 +/- 522.6 ng/1; n = 19) and those without these antigens (393.7 + 556.2 ng/1; n = 38). Iron overload in haemodialysis patients is not a histocompatibility-linked disorder.
