The iron status of Italian subjects with beta-thalassemia trait

Serum iron, transferrin saturation, serum ferritin and urinary iron excretion have been tested in a group of Italian subjects with beta-thalassemia trait. A number of these subjects, mostly men, had signs of increased iron load. Serum ferritin was the most sensitive index among those measured for detection of iron overload and was positively correlated with desferrioxamine-induced urinary iron excretion. Italian males with beta-thalassemia trait may be at high risk of developing iron overload even without prolonged iron or transfusional therapy.
