Endocrinopathies in Turkish Children with Thalassemia Major

Aim: Endocrinopathies are common in patients with thalassemia major (TM) and affect their life quality. Our aim was to identify the frequency of growth retardation and endocrine complications in these patients. Materials and Methods: Sixty-two patients aged 3-18 years with TM were evaluated retrospectively for height, weight, body mass index (BMI), and pubertal stage. Blood tests for endocrine function, and oral glucose tolerance test (OGTT) results were recorded. Results: The mean age of 62 subjects (33 females/29 males) was 10.4±3.9 years. The frequency of ≤-2 standard deviation scores was 37.1% for height, 33.9% for weight and 11.3% for BMI. Short stature, being underweight, and low BMI were significantly more prevalent in children over 7 years old (p<0.001). Delayed puberty/hypogonadism was present in 37% of 19 adolescents. Thirteen percent of the subjects had vitamin D deficiency (
