Core Tip
Core tip: Our retrospective cohort study of cystic fibrosis (CF) patients with hepatic steatosis demonstrates that hepatic steatosis in CF is associated with a higher body mass index as well as a higher percent predicted forced expiratory volume in 1 s, as compared to normal CF controls. None of our patients with hepatic steatosis exhibited evidence for advanced liver disease. Our findings are novel and demonstrate similarities between hepatic steatosis in CF and adult non-alcoholic fatty liver disease and future prospective studies are required to determine whether this steatosis may evolve into cirrhosis.
