Abstract
Clinical advances in the treatment of thalassaemia major (TM) patients have helped to increase substantially the life expectancy of patients. The TM patients today represent the first generation of adult thalassemics. As patients enter puberty, they begin to experience a variety of endocrine abnormalities, presumably the results of chronic anaemia and tissue iron deposition from the chronic transfusion therapy. In patients with TM, the anterior pituitary gland is particularly sensitive to free radical stresses. Recent reports have documented a frequency of severe growth hormone deficiency in 13–32% of adult patients with TM. The prevalence of impaired adrenal function in TM patients has been reported from 0 to 33%, depends on the age of the population studied, although clinical adrenal insufficiency (AI) is rare. Thyroid dysfunction has been observed in 13–60% of patients, but its severity is variable in different series. Acquired central hypothyroidism (CH) is a rare complication.
