ABSTRACT
Aim: Statins are associated with lower risk of gallstones due to anti-inflammatory effects. We assessed whether statins impact circulating inflammation among Chilean women with gallstones. Materials & methods: 200 Mapuche women were matched on statin use and age to 200 non-Mapuche women in the Chile Biliary Longitudinal Study. We analyzed 92 inflammatory biomarkers using multivariable-adjusted regression models, random forests and pathway analyses. Results: Statins were not significantly associated with any inflammation marker when women were analyzed jointly or stratified by ancestry. No significant associations were found through random forest methods and pathway analyses. Discussion: We did not find significant associations between statin use and inflammation markers in women with gallstones, suggesting that statins do not reduce inflammation once gallstones have formed.
Statins are prescribed to lower cholesterol and can also decrease the risk of gallstone formation by reducing inflammation. We assessed whether statin use reduces inflammation among women who have already developed gallstones. We analyzed 92 inflammation markers among 400 women in Chile, including 200 women with Mapuche Amerindian ancestry and 200 women of Latina/European ancestry. We found that statin use was not correlated with inflammation in this group of women overall nor by ancestry. This may mean that statin use does not reduce inflammation in women who already were diagnosed with gallstones.
