Abstract
We present the case history of a boy, who died at the age of 31/2; years after a rapidly progressive neurologic disorder, characterized by psychomotor retardation, hypotonia, hemiparesis, seizures and myoclonic contractions. Histopathological studies showed slight lipid storage in liver. Autopsy showed the characteristic features of progressive infantile poliodystrophy (Alpers' disease); ultrastructural examination showed an increased density of mitochondria in cerebral gray matter. Biochemical studies in leukocytes, cultured fibroblasts and liver indicated a deficiency in the citric acid cycle between succinate and fumarate; this deficiency was not present in muscle tissue.
This study supports the view that progressive infantile poliodystrophy is associated with abnormalities in pyruvate metabolism and/or in cell mitochondria.
