Abstract Background Celiac disease (CD) is an immune-mediated intolerance to gluten .CD has been recognized as a multisystem disorder which may affect other extra intestinal organs, such as the skin, thyroid, heart, nervous system, pancreas and liver. Individuals with CD are at increased risk of liver disease namely cryptogenic liver disorder and autoimmune liver disorder. However, until now, it remains unknown whether these two forms of liver disease are really different entities or only different severities of the same disorder. Objective To evaluate the association of CD with autoimmune hepatitis in pediatrics. Subjects and Methods This was a cross-sectional study that was conducted at the Pediatric Hepatology Clinic and Pediatric Gastroenterology Clinic, Children’s Hospital, Ain Shams University. The study included 2 groups of patients each comprised 20 children and adolescents as follow: Group I: Patients with established diagnosis of autoimmune hepatitis (AIH). All patients were receiving corticosteroids and azathioprine Group II: Patients with established diagnosis of CD. In group I patients with AIH, CD was screened for using anti-tissue transglutaminase (tTG) IgA in addition to measuring serum IgA to determine the need to measure anti-tTG IgG. Immunological markers (ANA, anti-smooth muscle antibody (ASMA) and liver and kidney microsomal (LKM) antibodies in addition to protein electrophoresis were done for group II patients with CD to screen for AIH. Results All patients in group I with AIH had normal serum IgA levels and were found negative for anti-tTG IgA. Also, group II patients with CD were negative for ANA, ASMA and LKM antibodies with normal protein electrophoresis. Conclusion The current study showed that CD does not seem to have significant association with AIH, however, the small sample size is a study limitation. Further wider scale studies are needed to evaluate the risk of AIH in CD.
