Hepatic disease in patients with the acquired immune deficiency syndrome (AIDS).

The spectrum of liver disease in patients with acquired immune deficiency syndrome (AIDS) and the clinical impact of diagnostic percutaneous liver biopsy in this population were evaluated by a retrospective review of hepatic histology, clinical features and laboratory data in 85 patients (26 biopsies, 59 autopsies). Only 1 (3.8%) biopsy and 9 (15%) postmortem livers were histologically normal. Macrosteatosis and nonspecific portal inflammation were the most common histologic abnormalities. Intrahepatic AIDS-specific opportunistic infections or malignancies were detected in 42% of both biopsy and autopsy groups, with Mycobacterium avium-intracellulare the most frequent pathogen seen. Kaposi's sarcoma, although not detected on biopsy, was the most common postmortem AIDS-related hepatic finding. Intrahepatic lymphoma, cytomegalovirus hepatitis and hepatic mycoses were less frequently observed. In general, hepatic involvement represented part of a previously diagnosed, widely disseminated disease process, and liver biopsy led to new AIDS-specific diagnoses in only two patients. We conclude that while liver biopsy is a useful diagnostic tool in selected patients with AIDS, the information provided by biopsy rarely influences therapy or leads to improved survival.
