Human immunodeficiency virus infection and autoimmune hepatitis during highly active anti-retroviral treatment: a case report and review of the literature.

INTRODUCTION: The emergence of hepatic injury in patients with human immunodeficiency virus infection during highly active therapy presents a diagnostic dilemma. It may represent treatment side effects or autoimmune disorders, such as autoimmune hepatitis, emerging during immune restoration. CASE
PRESENTATION: We present the case of a 42-year-old African-American woman with human immunodeficiency virus infection who presented to our emergency department with severe abdominal pain and was found to have autoimmune hepatitis. A review of the literature revealed 12 reported cases of autoimmune hepatitis in adults with human immunodeficiency virus infection, only three of whom were diagnosed after highly active anti-retroviral treatment was initiated. All four cases (including our patient) were women, and one had a history of other autoimmune disorders. In our patient (the one patient case we are reporting), a liver biopsy revealed interface hepatitis, necrosis with lymphocytes and plasma cell infiltrates and variable degrees of fibrosis. All four cases required treatment with corticosteroids and/or other immune modulating agents and responded well.
CONCLUSION: Our review suggests that autoimmune hepatitis is a rare disorder which usually develops in women about six to eight months after commencing highly active anti-retroviral treatment during the recovery of CD4 lymphocytes. It represents either re-emergence of a pre-existing condition that was unrecognized or a de novo manifestation during immune reconstitution.
