The clinical phenotype of multiple acyl-CoA dehydrogenase deficiency in infancy is characterized by recurrent episodes of hypoketotic hypoglycemia and lipid storage myopathy. Brain damage has been described only as a consequence of severe and protracted hypoglycemia. We describe a child who experienced normal physical and psychomotor development until the age of 3 years, who then developed progressive intention tremors, dysarthria, ataxia, and spastic tetraparesis. Episodes of acute metabolic distress were never observed. Magnetic resonance imaging disclosed abnormal signals within the white matter of the brain and cerebellum, suggesting leukodystrophy. Gas chromatography/mass spectrometry analysis revealed abnormally high levels of glutaric acid, dicarboxylic acids, and glycine derivatives in urine. Riboflavin therapy was initiated at 4 years of age, when the patient had already lost control of trunk and head posture. Consistent improvement rapidly occurred after riboflavin supplementation. Glutaric aciduria type II may cause brain damage, in spite of the absence of acute metabolic distress, and should be considered in the differential diagnosis of leukodystrophies.

Cardiomyopathy and leukodystrophy are life-threatening complications of multiple acyl-CoA dehydrogenase deficiency (MADD). A 2-year-old boy with this disorder developed rapidly progressive leukodystrophy resulting in complete paralysis within 4 months. Within a week of starting sodium-D,L-3-hydroxybutyrate he had improved. After 2 years, neurological function returned, including walking independently, with progressive improvement of brain MRI. Two additional infants with MADD developed life-threatening cardiomyopathy unresponsive to conventional treatment. On sodium-D,L-3-hydroxybutyrate treatment their cardiac contractility showed progressive and sustained improvement. D,L-3-hydroxybutyrate is a therapeutic option for cerebral and cardiac complications in severe fatty acid oxidation defects.
