    Abstract:
    High Hb level transfusion scheme for treatment of thalassemia mayor has improved life prognosis but has increased also the incidence of Diabetes Mellitus. 10 patients with thalassemia major have been followed with OGTT for a period 4 years long (1979-1982). In 1979 we changed from low to high level transfusion regimen, and we began to use the pump for slow subcutaneous administration of desferrioxamine to treat iron overload. The results we obtained show a progressive increase of the average values in the insulinemic and glycemic plasma concentration from year to year. At the beginning of the follow-up period, insulinemic and glycemic values after OGTT showed a primitive pancreatic damage which evolved towards a better pancreatic function with the appearance of a peripheral insulin resistance. It is probable that both chronic hypoxia (low Hb level) and the iron overload (high Hb level) may cause, with different processes, an impairment of glucose metabolism.
