A study on endocrine dysfunction in thalassaemia.

The aim was to study the prevalence and severity of hormonal imbalance affecting growth, gonadal and thyroid function in thalassaemic patients and to find out whether any correlation exists between the degree of tissue iron-overload and several patients characteristics like age, gender, foetal haemoglobin (HbF) level, type of thalassaemia (beta or E-beta), and the presence of specific endocrine abnormality. Sixty-eight consecutive non-chelated, transfusion-dependent patients of beta and E-beta-thalassaemia with significant tissue iron overload (serum ferritin more than 2000 microg/l) were included. Standing height was noted and clinical features of hypogonadism were recorded.
