OBJECTIVES: I. Determine the effectiveness of oral bile acid therapy with cholic acid, chenodeoxycholic acid, and ursodeoxycholic acid in patients with peroxisomal disorders involving impaired primary bile acid synthesis.
II. Determine whether suppression of synthesis of atypical bile acids and enrichment of bile acid pool with this regimen is effective in treating this patient population and improving quality of life.
PROTOCOL OUTLINE: Patients receive oral cholic acid and oral chenodeoxycholic acid on day 1. On day 4, patients receive oral cholic and ursodeoxycholic acids. Patients are assessed at 3 and 6 months for liver function response, neurologic status, and nutritional status.
Patients receive treatment until disease progression or unacceptable toxic effects are observed.
Primary Purpose: Treatment

OBJECTIVES: I. To Evaluate the therapeutic efficacy of cholic acid during provision of compassionate treatment to patients with identified inborn errors of bile acid synthesis and metabo...
The primary purpose of the study is to evaluate the therapeutic efficacy and safety of cholic acid in subjects with identified inborn errors of bile acid synthesis.
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 stu...
OBJECTIVES: I. Determine the optimum dose of tauroursodeoxycholic acid (TUDCA) required to achieve maximal bioavailability for patients with cystic fibrosis-associated liver disease. II....
In vitro findings have established that ursodeoxycholic acid is a surrogate for deoxycholic acid in preventing the growth of C. difficile, and interrupting recurrence. Investigators will a...
Clonorchiasis is a neglected tropical disease caused by Chinese liver fluke, Clonorchis sinensis infection. C. sinensis is a biological carcinogen causing cholangiocarcinoma in humans. In the mammalia...
Six cholic acid derivatives (1 - 6) were isolated from broth cultures of Bacillus amyloliquefaciens UWI-W23, an isolate from the Trinidad Pitch Lake. The compounds were extracted via solvent extractio...
Supplementation of a high-fat obesogenic diet (HFD) with cholic acid (CA) suppresses the development of obesity, insulin resistance, and hepatic steatosis in mice.
Background Infantile free sialic acid storage disease (ISSD) is a severe multisystemic disorder characterized by the accumulation of free sialic acid in lysosomes. Case presentation The patient presen...
Liver is the primary acting site of insulin. In this study, we developed innovative nanoparticles for oral and liver-targeted delivery of insulin by using enterohepatic circulation of bile acids. The ...
An early onset form of phytanic acid storage disease with clinical and biochemical signs different from those of REFSUM DISEASE. Features include MENTAL RETARDATION; SENSORINEURAL HEARING LOSS; OSTEOPOROSIS; and severe liver damage. It can be caused by mutation in a number of genes encoding proteins involving in the biogenesis or assembly of PEROXISOMES.
A 20-carbon branched chain fatty acid. In phytanic acid storage disease (REFSUM DISEASE) this lipid may comprise as much as 30% of the total fatty acids of the plasma. This is due to a phytanic acid alpha-hydroxylase deficiency.
A semisynthetic bile acid made from cholic acid. It is used as a cholagogue, hydrocholeretic, diuretic, and as a diagnostic aid.
An epimer of chenodeoxycholic acid. It is a mammalian bile acid found first in the bear and is apparently either a precursor or a product of chenodeoxycholate. Its administration changes the composition of bile and may dissolve gallstones. It is used as a cholagogue and choleretic.
The glycine conjugate of CHOLIC ACID. It acts as a detergent to solubilize fats for absorption and is itself absorbed.
Hepatology is the study of liver, gallbladder, biliary tree, and pancreas, and diseases associated with them. This includes viral hepatitis, alcohol damage, cirrhosis and cancer. As modern lifestyles change, with alcoholism and cancer becoming more promi...
