Purpose

OBJECTIVES: I. Determine the pharmacokinetics of sodium dichloroacetate (DCA) in patients with congenital lactic acidemia.

II. Determine the efficacy of DCA in decreasing the frequency and/or severity of acute episodes of acidotic illness, improving linear growth, improving neurological or developmental function, or slowing neurological or developmental deterioration in these patients.

Detailed Description:

PROTOCOL OUTLINE: This is a randomized, double blind, cross over study. Patients are randomized to start with one of two different doses of sodium dichloroacetate (DCA).

Patients receive one of two doses of oral DCA for 6 months, then switch to the alternate dose for 6 months. This course is repeated once.

Patients are followed for up to 2 years.

Ages Eligible for Study:	3 Months and older
Genders Eligible for Study:	Both
