Is Aspartate Aminotransferase to Platelet Ratio Index a Better Noninvasive Score for Predicting Advanced Fibrosis in Nonalcoholic Fatty Liver Disease Patients?

Abstract

In the 21st century, nonalcoholic fatty liver disease (NAFLD) is the most prevalent liver disorder. The prevalence of NAFLD within the general population in India ranges from 9 to 53%. The gold standard for assessing the severity of liver fibrosis is liver biopsy. However, due to various difficulties involved with liver biopsy, it is imperative to identify different non-invasive tools that can replace liver biopsy. A prospective observational study of 130 patients meeting the inclusion criteria for NAFLD was done for a period of 18 months. We aimed to compare the performance characteristics of different noninvasive scores [fibrosis-4 (FIB-4) score, nonalcoholic fatty liver disease fibrosis score (NFS), and aspartate aminotransferase to platelet ratio index (APRI)] in predicting advanced fibrosis as assessed by FibroScan. In the study, 76.9% of patients were male. Advanced fibrosis was seen in 12.3% of the patients. Majority of the patients with advanced fibrosis had metabolic syndrome. Based on the area under the receiver operating characteristic curve (AUROC), the new cut-off for ruling out advanced fibrosis for FIB-4, NFS, and APRI were 1.18, -0.9, and 0.65, respectively, and APRI had the best AUROC (0.768). Abnormal glycemic status and metabolic syndrome were risk factors for advanced fibrosis. The newly derived cut-offs for the FIB-4 score, NFS score, and APRI score had a better Negative predictive value compared to the original cut-offs. Bhayani PD, Parameswaran SA, Palaniswamy KR, et al.
