  • Background: Patients with chronic hepatitis C virus (HCV) infection may be prescribed statins for metabolic/cardiovascular disease, but it remains unclear if the risk of acute liver injury (ALI) associated with statin use is higher for chronic HCV-infected persons.

    Methods: We conducted a cohort study among  3,768 chronic HCV-infected statin initiators, 23,535 HCV-uninfected statin initiators, 12,073 chronic HCV-infected statin non-users, and 30,808 HCV-uninfected statin non-users in the Veterans Aging Cohort Study from 2000-2012. We determined development of: 1) liver aminotransferases >200 U/L, 2) severe ALI (international normalized ratio ³1.5 and total bilirubin >2 times upper limit of normal (ULN)), 3) hospitalization with an ALI diagnosis, and 4) all-cause mortality. Cox regression was used to determine propensity score-adjusted hazard ratios (HRs) with 95% confidence intervals (CI).  

    Results: Chronic HCV-infected statin initiators had higher risks of liver aminotransferases >200U/L, severe ALI, hospitalization with ALI, and death, than HCV-uninfected statin initiators.   In contrast, HCV-infected statin initiators had lower risks of liver aminotransferases >200 U/L, severe ALI, hospitalization with severe ALI, and death compared those HCV-infected not using statins.  The risk of death was lower for HCV-infected statin initiators than HCV-uninfected statin non-users.

    Conclusion: Chronic HCV-infected statin initiators had a higher risk of ALI events and death than HCV-uninfected statin initiators but a lower risk of ALI outcomes and death than chronic HCV-infected statin non-users and lower risk of death than HCV-uninfected statin non-users.
