Prevalence of and Risk Factors for Liver Enzyme Elevation After Hepatitis C Virologic Cure.

A subset of patients with chronic hepatitis C virus (HCV) infection demonstrate liver enzyme elevation (LEE) after achieving sustained virologic response (SVR). Risk factors for LEE are not well characterised. We conducted a single-centre retrospective cohort study of adults with HCV infection in the Duke University Health System who received direct-acting antiviral therapy and achieved SVR. We performed multivariable logistic regression to assess the relationship between potential risk factors and LEE. We used generalised linear mixed-effects models to explore longitudinal relationships between HIV and LEE. Among 1356 patients, 556 (41.0%) had LEE after achieving SVR. Higher pretreatment alanine aminotransferase (ALT) (adjusted odds ratio [aOR] 1.08 per 10 IU/L increase; 95% confidence interval [CI] 1.05-1.11) and pretreatment cirrhosis (aOR 2.26, 95% CI 1.60-3.21) were associated with higher odds of LEE; male sex was associated with lower odds of LEE (aOR 0.28, 95% CI 0.21-0.38). There was insufficient evidence of an association between HIV and LEE (aOR 0.83, 95% CI 0.47-1.44). Pretreatment ALT, cirrhosis and female sex predicted LEE in this cohort of patients with HCV infection who achieved SVR. These findings can help to identify patients at greatest risk of post-SVR liver injury.
