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.

Condition	Treatment or Intervention
Infantile Refsum's Disease Zellweger Syndrome Bifunctional Enzyme Deficiency Adrenoleukodystrophy	Drug: chenodeoxycholic acid  Drug: cholic acid  Drug: ursodiol

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.

Ages Eligible for Study:  up to  5 Years,  Genders Eligible for Study:  Both

Criteria

Biochemically proven peroxisomal disorder, including:

• Zellweger syndrome
• Pseudo-Zellweger syndrome
• Neonatal adrenoleukodystrophy
