Study of Thyroid Function in Children With Beta-Thalassemia Major

Area of Science:

• Endocrinology
• Hematology
• Pediatrics

Background:

• Beta-thalassemia major requires frequent blood transfusions, leading to iron overload.
• Iron overload causes significant complications, including endocrine dysfunction such as hypothyroidism.
• Thyroid dysfunction is a common comorbidity in transfusion-dependent thalassemia patients.

Purpose of the Study:

• To investigate the prevalence of thyroid dysfunction in children with beta-thalassemia major.
• To determine the correlation between iron overload (serum ferritin levels) and thyroid function.
• To emphasize the importance of periodic thyroid function evaluation in these patients.

Main Methods:

• Observational analytical study of 40 children (2-18 years) with beta-thalassemia major.
• Measurement of serum ferritin and thyroid function tests (including TSH).
• Correlation analysis between serum ferritin levels and thyroid status (euthyroid, subclinical, and overt hypothyroidism).

Main Results:

• Out of 40 patients, 32.5% exhibited hypothyroidism (20% subclinical, 12.5% overt).
• Patients with serum ferritin >2000 ng/ml showed a 50% rate of hypothyroidism.
• A statistically significant positive correlation was found between elevated serum ferritin levels and increased TSH, indicating hypothyroidism.

Conclusions:

• Hypothyroidism is prevalent in children with beta-thalassemia major, often linked to iron overload.
• Periodic thyroid function screening is essential for early detection and management.
• Timely intervention for hypothyroidism can improve the overall quality of life for thalassemia patients.
