Autoimmune thyroid diseases (ATDs) are the most frequent extrahepatic autoimmune disorders among patients with AIH.

All patients were tested for free triiodothyronine (FT3), free tetraiodothyronine (FT4), thyroid stimulating hormone (TSH), anti-thyroid peroxidase (anti-TPO) and antithyroglobulin (anti-TG).

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.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Autoimmune hepatitis in Egyptian children is commonly associated with other autoimmune diseases.
