Surgical pathology of the liver in HIV infection.
In the 6-year period 1984-1989, 101 liver biopsies or 'needle necropsies' from human immunodeficiency virus positive patients were examined histologically. Of these, only nine showed no abnormality whatsoever. The commonest histological findings were either fatty change or changes related to co-existent chronic viral hepatitis. Granulomas were seen in 15 cases, four of which were positive for acid-fast bacilli. A range of organisms were recorded: cytomegalovirus (4); Histoplasma capsulatum (1); Pneumocystis carinii (2); Cryptococcus neoformans (1); and Leishmania donovani (1). There were two cases of non-Hodgkin's lymphoma, but no cases of Kaposi's sarcoma. Marked iron deposition, which correlated with multiple blood transfusions was seen in nine biopsies. We were unable to identify any histological feature in the liver as being specific for HIV infection. The high incidence of liver abnormalities reflects: (i) the coincident exposure to hepatotropic viruses; (ii) the presence of opportunistic infections and neoplasms, usually part of a disseminated multi-organ process arising in the setting of profound immune depression; (iii) iatrogenic causes, in particular iron overload related to multiple blood transfusions received for treatment of zidovudine-induced anaemia; and (iv) non-specific changes associated with chronic debilitating disease.
