Statins Are Associated With a Decreased Risk of Severe Liver Disease in Individuals With Noncirrhotic Chronic Liver Disease

Clin Gastroenterol Hepatol. 2024 Apr;22(4):749-759.e19. doi: 10.1016/j.cgh.2023.04.017. Epub 2023 Apr 28.


Background & aims: Little is known about the potential impact of statins on the progression of noncirrhotic chronic liver diseases (CLDs) to severe liver disease.

Methods: Using liver histopathology data in a nationwide Swedish cohort, we identified 3862 noncirrhotic individuals with CLD and statin exposure, defined as a statin prescription filled for 30 or more cumulative defined daily doses. Statin users were matched to 3862 (statin) nonusers with CLD through direct 1:1 matching followed by propensity score matching. Cox regression was used to estimate hazard ratios (HRs) for the primary outcome of incident severe liver disease (a composite of cirrhosis, hepatocellular carcinoma, and liver transplantation/liver-related mortality).

Results: A total of 45.3% of CLD patients had nonalcoholic fatty liver disease, 21.9% had alcohol-related liver disease, 17.7% had viral hepatitis, and 15.1% had autoimmune hepatitis. During follow-up evaluation, 234 (6.1%) statin users vs 276 (7.1%) nonusers developed severe liver disease. Statin use was associated with a decreased risk of developing severe liver disease (HR, 0.60; 95% CI, 0.48-0.74). Statistically significantly lower rates of severe liver disease were seen in alcohol-related liver disease (HR, 0.30; 95% CI, 0.19-0.49) and in nonalcoholic fatty liver disease (HR, 0.68; 95% CI, 0.45-1.00), but not in viral hepatitis (HR, 0.76; 95% CI, 0.51-1.14) or autoimmune hepatitis (HR, 0.88; 95% CI, 0.48-1.58). Statin use had a protective association in both prefibrosis and fibrosis stages at diagnosis. Statin use was associated with lower rates of progression to cirrhosis (HR, 0.62; 95% CI, 0.49-0.78), hepatocellular carcinoma (HR, 0.44; 95% CI, 0.27-0.71), and liver-related mortality (HR, 0.55; 95% CI, 0.36-0.82).

Conclusions: Among individuals with noncirrhotic CLD, incident statin use was linked to lower rates of severe liver disease, suggesting a potential disease-modifying role.
