- Abstract
Background: HIV-monoinfected individuals are at high risk of nonalcoholic fatty liver disease. Noninvasive tests of steatosis, nonalcoholic steatohepatitis (NASH), and fibrosis have been poorly assessed in this population. Using liver biopsy (LB) as a reference, we assessed the accuracy of noninvasive methods for their respective diagnosis: magnetic resonance imaging proton-density-fat-fraction (MRI-PDFF), FibroScan/controlled attenuation parameter (CAP), and biochemical tests., Methods: We enrolled antiretroviral therapy-controlled participants with persistently elevated transaminases and/or metabolic syndrome, and/or lipodystrophy. All had hepatic MRI-PDFF, FibroScan/CAP, FibroTest/NashTest/SteatoTest, APRI, FIB-4, and nonalcoholic fatty liver disease-fibrosis score. A LB was indicated if suspected significant fibrosis (FibroScan ≥7.1 kPa and/or FibroTest ≥0.49). Performance was considered as good if area under a receiver operating characteristic curves (AUROCs) was >0.80., Results: Among the 140 patients with suspected significant fibrosis out of the 402 eligible patients, 49 had had a LB: median age of 54 years (53-65), body mass index: 26 kg/m (24-30), steatosis in 37 (76%), NASH in 23 (47%), and fibrosis in 31 (63%) patients [F2: 7 (14%); F3: 6 (12%); and F4: 2 (4%)]. Regarding steatosis, MRI-PDFF had excellent and CAP good performances with AUROCs at 0.98 (95% confidence interval: 0.96 to 1.00) and 0.88 (0.76 to 0.99), respectively, whereas the AUROCs of SteatoTest was 0.68 (0.51 to 0.85). Regarding fibrosis (≥F2), APRI and FIB-4 had good performance with AUROCs at 0.86 (0.74 to 0.98) and 0.81 (0.67 to 0.95). By contrast, FibroScan and FibroTest had poor AUROCs [0.61 (0.43 to 0.79) and 0.61 (0.44 to 0.78)], with very low specificity. Regarding NASH, alanine aminotransferase ≥36 IU/L had good performance with AUROCs of 0.83 (0.71 to 0.94), whereas the NashTest had an AUROC of 0.60 (0.44 to 0.76)., Conclusions: In HIV-monoinfected patients, MRI-PDFF and FibroScan/CAP are highly accurate for the diagnosis of steatosis. The alanine aminotransferase level and APRI should be considered for the detection of NASH and fibrosis.
