Impact of Human Immunodeficiency Virus Infection on Liver and Cardiovascular Outcomes in Veterans with Metabolic Dysfunction Associated Steatotic Liver Disease.

OBJECTIVE: Hepatic steatosis in highly prevalent in people living with human immunodeficiency virus (HIV). It remains unclear whether HIV in patients with metabolic dysfunction associated steatotic liver disease (MASLD) is associated with greater risks of liver disease progression and cardiovascular disease (CVD). We aim to evaluate the impact of HIV infection on risks of liver and CVD outcomes among U.S. Veterans with MASLD.

METHODS: Using national Veterans Administration data from 2010-2022, we created a propensity score matched cohort of MASLD patients with vs. without HIV. Primary outcomes were incidence of cirrhosis and hepatocellular carcinoma (HCC) among patients with vs. without HIV as well as MASLD-HIV patients on anti-retroviral therapy (ART) vs. not on ART. Secondary outcomes included incidence of major adverse cardiovascular events (MACE) and overall survival.

RESULTS: The propensity matched cohort included 920 MASLD patients with HIV and 920 MASLD patients without HIV and were similar in demographics and co-morbidities. Compared to MASLD patients without HIV, incidences of cirrhosis and HCC were similar among MASLD with HIV. Compared to MASLD patients without HIV, incidence of MACE was higher among MASLD patients with HIV (5.18 vs. 4.48 per 100 person-years, p=0.03). Overall 5-year survival was significantly lower among MASLD patients with HIV and even lower among those not on ART.

CONCLUSIONS: Among U.S. Veterans with MASLD, concurrent HIV infection, and particularly not being on ART, is associated with greater risks CVD and decreased overall survival. No differences in risks of cirrhosis or HCC were observed.
