Phase II Study of Cholesterol- and Cholestanol-Free Diet, Lovastatin, and Chenodeoxycholic Acid for Cerebrotendinous Xanthomatosis

June 23, 2005 updated by: National Center for Research Resources (NCRR)

Effects of Diet and Medication in Patients With Cerebrotendinous Xanthomatosis (CTX)

OBJECTIVES: I. Assess the biosynthesis of cholesterol and cholestanol, and measure the turnover of individual sterols and bile acids in patients with cerebrotendinous xanthomatosis before and after a cholesterol- and cholestanol-free diet.

II. Assess the biosynthesis of cholesterol and cholestanol, and measure the turnover of individual sterols and bile acids in these patients before and after lovastatin and chenodeoxycholic acid.
