Liver function tests and statins

Purpose of review To discuss recent data on statins in patients with elevated liver tests. Recent findings As a result of the obesity epidemic in Western societies, conditions associated with metabolic syndrome are increasing, including nonalcoholic fatty liver disease (NAFLD). Because most patients with metabolic syndrome have indications for statins, clinicians will be confronted with prescribing statins to patients with elevated liver tests. Statins are associated with elevations in aminotransferases in up to 3% of treated patients, but statins rarely lead to serious drug-induced liver injury (DILI), chronic liver disease, or acute liver failure. Data have emerged demonstrating that not only are statins well tolerated to use in most patients with elevated liver tests but also they may have a beneficial therapeutic effect in treating the underlying liver disease. Studies demonstrate that statins may increase response rates of antiviral therapy for hepatitis C. In a study of 437 patients with moderate elevations in baseline aminotransferases, patients on statins were more likely to have a decline in aminotransferases compared with untreated patients. Summary Data support using statins in patients with elevated liver tests, especially patients with NAFLD, who may be at particularly high risk for cardiovascular disease.
