Acute autoimmune hepatitis presenting with peripheral blood eosinophilia

Area of Science:

• Hepatology
• Immunology
• Hematology

Background:

• Peripheral blood eosinophilia is associated with various conditions, including allergic, infectious, neoplastic, and autoimmune diseases.
• Autoimmune hepatitis (AIH) is an immune-mediated liver disease, typically diagnosed via clinical, serological, and histopathological findings.

Observation:

• A case report details an 18-year-old male diagnosed with acute autoimmune hepatitis.
• The patient presented with moderate peripheral blood eosinophilia at the time of diagnosis.

Findings:

• Blood eosinophilia in AIH has not been previously reported in the absence of other autoimmune conditions.
• The patient's eosinophilia resolved within days of initiating corticosteroid therapy for AIH.

Implications:

• This case highlights a potentially novel presentation of autoimmune hepatitis.
• The rapid resolution of eosinophilia with AIH treatment suggests a possible link between the two conditions.
