Aim. Hemochromatosis (HH) was a common inherited disease characterized by iron overload. This disease is usually the result of mutations in the HLA-linked hemochromatosis gene (HFE). The aim of this study was to evaluate the frequency of HFE mutations in a group of Venetian hemodialysis patients.
Methods. Sixty-one hemodialysis patients, 62 patients with laboratory findings suggestive for iron overload, 57 repeat blood donors were enrolled in the study. HFE mutations were detected by using a commercial strip assay.
Results. In this study only H63D and C282Y mutations were observed. The overall prevalence of HFE mutations was 40.9% among hemodialysis patients, 30.6% among patients with laboratory findings of iron overload and 15.8% among blood donors.
Conclusion. A high prevalence of HFE mutation among hemodialysy patients was observed. Prevalence of HFE mutation in this group was 40.9%, significantly higher than results observed among blood donors (15.8%, P<0.005) or among patients with laboratory signs of iron overload (30.6%, P<0.01). These data are, at present inexplicable, and this results need further confirmation.
