Abstract
BACKGROUND

Abnormal liver chemistry is a common problem in human immunodeficiency virus (HIV)-infected patients. Common causes of abnormal liver enzymes in this population include viral hepatitis B/C or opportunistic infection, drug toxicity, and neoplasm. Autoimmune hepatitis is a rare cause of hepatitis in HIV-infected individuals; however, this condition has been increasingly reported over the past few years.

CASE SUMMARY

We present 13 HIV-infected patients (5 males and 8 females) who developed autoimmune hepatitis (AIH) after their immune status was restored, i.e. all patients had stable viral suppression with undetectable HIV viral loads, and median CD4+ counts of 557 cells/× 106 L. Eleven patients presented with chronic persistent elevation of aminotransferase enzyme levels. One patient presented with acute hepatitis and the other patient presented with jaundice. The median levels of aspartate aminotransferase and alanine aminotransferase enzymes were 178 and 177 U/mL, respectively. Elevation of immunoglobulin G levels was present in 11 (85%) patients. Antinuclear antibody and anti-smooth muscle antibody were positive in 11 (85%) and 5 (38%) patients. Liver biopsy was performed in all patients. They had histopathological findings compatible with AIH. The patients were started on prednisolone for remission induction, with good response. After improvement of the liver chemistry, the dose of prednisolone was tapered, and azathioprine was added as life-long maintenance therapy. At the last follow-up visit, all were doing well, without HIV viral rebound or infectious complications.

CONCLUSION

This report underscores the emergence of autoimmune hepatitis in the context of HIV infection.

Core tip: Elevated liver enzymes are a common problem in human immunodeficiency virus (HIV)-infected patients. Clinical manifestations of autoimmune hepatitis (AIH) range from no symptoms to mild chronic hepatitis to acute severe hepatitis leading to fulminant hepatic failure or cirrhosis. The diagnosis of AIH requires thorough investigation. It is crucial to perform liver biopsy to confirm the diagnosis. Although rare, AIH should be considered a differential diagnosis in HIV-infected patients presenting with elevated aminotransferase enzyme levels after the exclusion of other common causes of hepatitis. It is believed that this condition occurs due to immune reconstitution inflammatory syndrome (IRIS). Immunosuppressive drugs are the mainstay of treatment and can be used safely in HIV-infected patients.
