Findings and benefit of liver biopsies in 46 patients infected with human immunodeficiency virus.
OBJECTIVE
The aim of this work is to evaluate the role of liver biopsy and to determine the histological findings in patients infected with the human immunodeficiency virus (HIV) who have abnormal liver function tests (LFT).


METHODS
We performed a percutaneous liver biopsy in 46 HIV-seropositive patients with abnormal LFT. Parts of biopsied tissue were used for bacterial and fungal culture and the rest was processed for histological examination including special staining.


RESULTS
Of these 46 patients, 41 patients were males and five were females. The median age was 31+/-6 years. Mycobacterium tuberculosis was the most common histological finding (15 cases). Of 15 tuberculosis patients, 11 (73.3%) had lymphadenopathy and positive acid-fast bacilli (AFB) in node aspiration or biopsy. The other findings included AFB-negative granuloma (eight cases), histoplasmosis (six cases), cryptococcosis (six cases), penicillosis (four cases), viral hepatitis: hepatitis C virus (HCV; one case), hepatitis B virus and HCV infection (one case), fatty liver (two cases), drug-induced hepatitis (one case) and non-specific changes (five cases). There were double infections in three patients. We were able to demonstrate opportunistic infections in 41 cases (89.3%).


CONCLUSIONS
Mycobacterium tuberculosis was the most common histological finding in HIV patients with abnormal LFT in Thailand. Liver biopsy was a useful procedure in evaluating abnormal LFT in HIV patients.
