INTRODUCTION: Statins have been associated with improved clinical outcomes in patients with viral hepatitis and after variceal bleeding. Still, the clinical benefit of statins is not well defined for different liver diseases. Moreover, associations between statin use and liver stiffness as well as event free survival have not been established. METHODS: Liver stiffness was evaluated in 6490 patients with liver disease (January 2012 till December 2016). Two hundred thirty-four of those received statin therapy, 468 controls without statins were selected by a 1:2 case by case matching using age, sex, underlying liver disease and BMI. RESULTS: Statins were given to 234 patients with chronic virus hepatitis (n = 104), nonalcoholic fatty liver disease (n = 52), autoimmune liver disease including autoimmune hepatitis, primary biliary cholangitis and primary sclerosing cholangitis (n = 31) and hepatitis of unknown origin (n = 47). Follow-up data were available for 96 and 119 pairs (mean follow-up 2 years). Statin users showed reduced inflammatory activity. Elevated liver enzymes were reported in 57% of statin-treated compared with 70% of controls (mean alanine aminotransferase level 53 vs. 74 U/l; P < 0.001). Statin use was well tolerated in this cohort. Mean liver stiffness values were 10.7 kPa (SEM 0.7) and 15.5 kPa (SEM 0.7) accordingly (P < 0.0001). Decompensation was less likely to occur in the statin group, both groups do not defer in the incidence of liver tumor occurrence, transplantation or death (odds ratio = 1, P = nonsignificant). CONCLUSIONS: Use of statins was well tolerated irrespective of liver disease. Statin users showed reduced hepatic inflammatory activity, less severe markers of liver stiffness and portal hypertension. There might be a beneficial effect of statin on the risk to experience hepatic decompensation.
