Thyroid Disorders in Pediatric Autoimmune Hepatitis
Frequency of Thyroid Disorders in Pediatric Patients With Autoimmune Hepatitis at Assiut University Children's Hospital
調査の概要
詳細な説明
Autoimmune hepatitis is frequently associated with other autoimmune disorders, particularly autoimmune thyroid diseases. Thyroid dysfunction in children may remain asymptomatic yet affect growth and development.
This observational study will include children less than 18 years diagnosed with autoimmune hepatitis according to the Revised International Autoimmune Hepatitis Group (IAIHG) scoring system. All participants will undergo thyroid function tests (TSH, FT3, FT4), thyroid autoantibodies (anti-TPO, anti-Tg), and thyroid ultrasonography.
