    Abstract:
    We present data of a detailed study of endocrine function in 50 patients (21 males, 29 females) with thalassaemia intermedia, 15-46 years old (mean age 28.7 yr), with raised serum ferritin levels (mean 1540 micrograms/l). Mean haemoglobin concentration was 8.1 g/dl. Half of them had had more than 50 transfusions in their life and had received irregular intramuscular or subcutaneous chelation therapy. Delayed puberty was one of the most frequent (36%) clinical endocrine abnormalities found in our patients. Primary amenorrhea was observed in two patients and secondary amenorrhea in four patients. Two males, aged 19 and 36 years, had hypogonadism. A poor response to GnRH, found in three females and in both males tested, suggested that pituitary dysfunction was wholly or partially responsible for hypogonadism. Gonadal function was normal in all patients studied. Glucose intolerance and primary hypothyroidism were less frequent (24 and 5.7%, respectively) and milder than in thalassaemia major patients. Two patients had low T3 and T4 and normal basal and stimulated response of TSH to TRH. This condition has been found in euthyroid sick syndrome and it is likely that it represents an adaptive response by the body to minimize catabolism when undergoing major stress. As a consequence, we believe that periodic endocrine evaluation should be carried out in subjects with beta-thalassaemia intermedia, particularly in those over 14 years old, in order to detect and to treat endocrine dysfunction.
