title: A study on endocrine dysfunction in thalassaemia.
abstract: 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. Insulin tolerance test was done to assess growth hormone reserve. Serum oestradiol, T3,T4,TSH were measured in fasting clotted sample, while pooled sera (from 3 consevutive morning samples) was used for testosterone, FSH and LH. Hypogonadism was the commonest abnormality, both in males (52.28%) and females (35.89%) followed by growth retardation (20.58%) and reduced growth hormone reserve (7.35%). There was no significant difference in the prevalence of endocrine dysfunction with regard to patient's age, gender, type of thalassaemia (beta or E-beta) amd HbF level. Hypogonadic females had a significantly elevated mean serum ferritin level. Subclinical hypothyroidism was present in 23.52% of patients, related to the duration of disease. No association was found between pituitarty and thyroid dysfunction.
