Iron overload and lysosomal stability in beta zero-thalassaemia intermedia and trait: correlation between serum ferritin and serum N-acetyl-beta-D-glucosaminidase levels

Increased iron storage represents a characteristic condition in patients with beta zero-thalassaemia intermedia. Iron overload is an important factor in cellular damage. Recent studies have shown an enhanced lysosomal fragility due to increased iron storage. 13 patients with beta-thalassaemia intermedia, aged 17-44 years, were studied. Both serum ferritin and serum N-acetyl-beta-D-glucosaminidase levels were evaluated in all subjects studied. A significant linear correlation (P less than 0.05) between serum ferritin and serum N-acetyl-beta-D-glucosaminidase levels were found.
