Background Liver disease is an important cause of morbidity and mortality in people living with human immunodeficiency virus (PLWH), of which nonalcoholic fatty liver disease (NAFLD) is an increasingly recognized cause. There are limited data investigating NAFLD in HIV monoinfection and histologically defined disease. We aimed to identify who is at risk of fibrosis, NAFLD, and nonalcoholic steatohepatitis (NASH) among PLWH and explore the diagnostic accuracy of noninvasive markers of fibrosis. Methods This was a retrospective, cross-sectional, international, multicenter study including patients with HIV monoinfection, without chronic viral hepatitis or other known causes of chronic liver disease, who underwent liver biopsy for abnormal liver biochemistry and/or clinical suspicion of liver fibrosis. Results A total of 116 patients from 5 centers were included. Sixty-three (54%) had NAFLD, of whom 57 (92%) had NASH. Overall, 36 (31%) had advanced fibrosis (≥F3) and 3 (3%) had cirrhosis. Of the 53 cases without NAFLD, 15 (28%) had advanced fibrosis. Collagen proportionate area was similar between cases with and without NAFLD (3% vs 2%). Body mass index was independently associated with NAFLD (aOR, 1.2; 95% CI, 1.08–1.34), and type 2 diabetes was independently associated with advanced fibrosis (aOR, 3.42; 95% CI, 1.00–11.71). The area under the curve for advanced fibrosis was 0.65 and 0.66 for both NAFLD Fibrosis Score (NFS) and FIB-4. Cutoff values of −1.455 (NFS) and 1.3 (FIB-4) have negative-predictive values of 0.80 and 0.82, respectively. Conclusions Advanced fibrosis is strongly associated with type 2 diabetes in PLWH. Serological markers require further optimization. [ABSTRACT FROM AUTHOR]
