Background Nonalcoholic fatty liver disease (NAFLD) is frequent in people with human immunodeficiency virus (PWH). The Fibroscan–aspartate aminotransferase (FAST) score was developed to identify patients with nonalcoholic steatohepatitis (NASH) and significant fibrosis. We investigated prevalence of NASH with fibrosis and the value of FAST score in predicting clinical outcomes in PWH. Methods Transient elastography (Fibroscan) was performed in PWH without viral hepatitis coinfection from 4 prospective cohorts. We used FAST >0.35 to diagnose NASH with fibrosis. Incidence and predictors of liver-related outcomes (hepatic decompensation, hepatocellular carcinoma) and extrahepatic events (cancer, cardiovascular disease) were evaluated through survival analysis. Results Of the 1472 PWH included, 8% had FAST >0.35. Higher body mass index (adjusted odds ratio [aOR], 1.21 [95% confidence interval {CI}, 1.14–1.29]), hypertension (aOR, 2.24 [95% CI, 1.16–4.34]), longer time since HIV diagnosis (aOR, 1.82 [95% CI, 1.20–2.76]), and detectable HIV RNA (aOR, 2.22 [95% CI, 1.02–4.85]) were associated with FAST >0.35. A total of 882 patients were followed for a median of 3.8 years (interquartile range, 2.5–4.2 years). Overall, 2.9% and 11.1% developed liver-related and extrahepatic outcomes, respectively. Incidence of liver-related outcomes was higher in patients with FAST >0.35 versus FAST ≤0.35 (45.1 [95% CI, 26.2–77.7] vs 5.0 [95% CI, 2.9–8.6] per 1000 person-years). FAST >0.35 remained an independent predictor of liver-related outcomes (adjusted hazard ratio, 4.97 [95% CI, 1.97–12.51]). Conversely, FAST did not predict extrahepatic events. Conclusions A significant proportion of PWH may have NASH with significant liver fibrosis. FAST score predicts liver-related outcomes and can help management of this high-risk population.
