Brief summary:
To evaluate the efficacy and safety of cholic acid therapy in treating lipodystrophy patients with hepatic steatosis. This is a randomized, double-blind, placebo-controlled cross-over study.

Detailed description:
Lipodystrophies are rare disorders characterized by selective loss of adipose tissue and predisposition to develop insulin resistance and its associated metabolic complications such as dyslipidemia, diabetes mellitus and hepatic steatosis. Nonalcoholic hepatic steatosis or steatohepatitis caused by excessive accumulation of triglycerides in hepatocytes, in fact, is a common feature of these disorders. Often a cause for significant morbidity and even mortality in lipodystrophic patients, hepatic steatosis poses a significant therapeutic challenge. Recent insight into the role of primary bile acids, cholic acid and chenodeoxycholic acid, which are endogenous ligands for the farnesoid X receptor (FXR), in regulating hepatic triglyceride homeostasis offers new treatment options for hepatic steatosis. Cholic acid was shown to inhibit hepatic triglyceride accumulation by more than 50% in a mouse model of hepatic steatosis and hypertriglyceridemia. Cholic acid has been previously used to treat inborn errors of bile acid synthesis in children without any side effects. In other studies in adults, cholic acid has been reported to be well tolerated. Therefore, we propose to investigate a potentially safe therapeutic option for its efficacy in reducing hepatic steatosis in patients with lipodystrophies.
