Prevalence of endocrinopathies in Turkish children with β-thalassemia major: A single-center study

Present chelation protocols have increased the life quality and survival of the patients with β-thalassemia major (BTM). However, endocrine complications are still mostly experienced. The aim of this study was to determine the prevalence of endocrine complications in children with BTM, and to study the relationship between serum ferritin levels and complications. Forty-five children (female: 23/male: 22, mean age: 12.39±3.72 y) with BTM were enrolled into the study. Blood samples were taken after an overnight fasting, early in the morning from entire study group. Median (range) serum ferritin of the patients was 1365 ng/mL (362 to 5996 ng/mL). The most prevalent endocrine complications were vitamin D insufficiency (54.5%), short stature (42%), pubertal impairment (25% for each sex), and osteopenia (13%), respectively. Ferritin levels were not correlated with anthropometric or laboratory data. Monitoring of growth, vitamin D status, and endocrine functions are essential to achieve a good quality of life in BTM patients. © 2016 Wolters Kluwer Health, Inc. All rights reserved
