Cholestasis is defined as the impairment in formation or excretion of bile from the liver to the intestine. It may result from defects in intrahepatic production of bile, impairment of hepatic transmembrane transporters, or mechanical obstruction to bile flow. In cholestasis, hepatocytes are exposed to high levels of bile acids, particularly those bearing hydrophobic properties. The increase in bile acids induces oxidative stress, leading to an imbalance in the prooxidant:antioxidant ratio which determines the final cellular redox status. This chapter will focus on the close relationship between bile acids and the most powerful endogenous antioxidant, coenzyme Q10 in cholestasis, and the eventual alternative therapeutic option of CoQ10 supplementation to current traditional therapies.
