Increasing prevalence of cirrhosis among U.S. adults aware or unaware of their chronic hepatitis C virus infection.

ABSTRACT:

Background & aims

Cirrhosis from hepatitis C virus (HCV) infection is a major cause of end-stage liver disease and hepatocellular carcinoma worldwide. We determine the prevalence of cirrhosis among HCV-infected American adults including those unaware of their infection.

Methods

Using the National Health and Nutrition Examination Survey (NHANES) data, we identified participants aged ⩾20 years with detectable serum HCV RNA. The prevalence of advanced fibrosis and cirrhosis was determined for eras 1 (1988-94), 2 (1999-2006) and 3 (2007-2012) by using FIB-4 >3.25 and APRI >2.0, respectively.

Results

Out of 52,644 NHANES examinees, 49,429 were tested for HCV, of whom 725 met the inclusion criteria (positive HCV RNA with available data for FIB-4 and APRI). Based on APRI, 6.
