Acetyl-CoA carboxylase inhibitors in non-alcoholic steatohepatitis: Is there a benefit?

Abstract

De novo lipogenesis (DNL) plays an important role in the pathogenesis of hepatic steatosis and also appears to be implicated in hepatic inflammation and fibrosis. Accordingly, the inhibition of acetyl-CoA carboxylase, which catalyzes the ratelimiting step of DNL, might represent a useful approach in the management of patients with nonalcoholic fatty liver disease (NAFLD). Animal studies and preliminary data in patients with NAFLD consistently showed an improvement in steatosis with the use of these agents. However, effects on fibrosis were variable and an increase in plasma triglyceride levels was observed. Therefore, more longterm studies are needed to clarify the role of these agents in NAFLD and to determine their risk/benefit profile.
