An Uncommon Presentation of Autoimmune Hepatitis in a Child With Thalassemia Trait

Autoimmune hepatitis (AIH) is quite rare in children. AIH is classified into two types based on the presence of autoantibodies: type 1 and type 2. The presentation of AIH varies, ranging from asymptomatic to acute or chronic hepatitis and occasionally fulminant liver failure. It can present at any age. In 20% of AIH cases, other autoimmune disorders might be present, such as diabetes mellitus and arthritis. A high index of suspicion is required for the early diagnosis of this condition. Pediatricians should consider the possibility of AIH in patients with jaundice once common causes are ruled out. The diagnosis is done on the basis of the presence of typical autoantibody titer, liver biopsy findings, and response to immunosuppressive medications. Some AIH patients may not respond to immunosuppressive therapy and may need a liver transplant. We present a case of a 12-year-old male child with thalassemia trait who was diagnosed with AIH.
