Background:
Autoimmune hepatitis (AIH) is an organ specific autoimmune disease, which can manifest at any age of life. there is a high prevalence of extrahepatic autoimmune diseases in patients with AIH. Autoimmune thyroid diseases (ATDs) are the most frequent extrahepatic autoimmune disorders among patients with AIH. Aim of work is to detect the frequency of ATDs among Egyptian children with AIH.
Methods:
This research is a cross-sectional study conducted on 58 children with AIH aged ≤ 18 years. All patients were tested for free triiodothyronine (FT3), free tetraiodothyronine (FT4), thyroid stimulating hormone (TSH), anti-thyroid peroxidase (anti-TPO) and antithyroglobulin (anti-TG). Thyroid ultrasound (US) and thyroid scan were performed for patients with abnormal thyroid profile, borderline values, positive anti-TPO or anti-TG.
Results:
The mean ± standard deviation (SD) for the age of the patients was 11.3 ± 4.5 years. Out of 58 patients of AIH, 28 patients (48.3%) had associated other autoimmune diseases. Autoimmune thyroiditis was the most common associated autoimmune disease being present in 10 patients (17.2%). The thyroid status of AIT patients showed that 6 patients (60%) were euthyroid, 3 patients (30%) had subclinical hypothyroidism and only one patient (10%) was hyperthyroid.
Conclusion:
Autoimmune hepatitis in Egyptian children is commonly associated with other autoimmune diseases. Autoimmune thyroiditis is the most common to be associated with AIH in pediatric patients. As it is not usually clinically manifesting, regular screening for AIT in children with AIH is mandatory.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
