December Liver Briefs

B Wildman-Tobriner et al. Gastoenterol 2018; 155: 1428-35.  This retrospective study which pooled data from 3 phase 2a trials with 370 subjects with nonalcoholic fatty liver disease (NAFLD) found that MRI iwth proton density fat fraction (PDFF) “did not accurately identify patients with NAS ≥4 (AUROC – 0.72) or fibrosis stage ≥3 (AUROC =0.66).”  Thus, this study indicates that currently liver histology remains the gold standard to determine severity of liver damage in paitents with NAFLD.

P Nahon et al. Gastroenterol 2018; 155: 1436-1450. This study looks closer at whether direct-acting antivirals (DAA) for hepatitis C could increase the risk of hepatocellular carcinoma (HCC) in patients (n=1270) with cirrhosis. The authors found that the crude 3-year cumulative incidence of HCC were 5.9% in the DAA and 3.1% in the SVR-IFN group. However, after Cox analysis, “we found no statistically significant increase in risk of HCC associated with DAA use (HR 0.89).”  The authors indicated that patient characteristics (age, diabetes, reduced liver function) and lower screening intensity were the reasons for the increased crude rates of HCC.
