title: [Carnitine deficiency in inborn errors of metabolism].
abstract: Several conditions, considered as inborn errors of metabolism, involve severe deficiencies in carnitine in both plasma and muscle. In the absence of evidence suggesting primary carnitine deficiency due to a biosynthetic enzymatic defect in the liver, the various diseases with carnitine deficiency are related to genetic defects in organic acid metabolism leading to blocked mitochondrial beta oxidation. We describe a 4.5-year-old boy and 2 female infants with glutaric aciduria type I, isovaleric acidemia, and long-chain acid dehydrogenase deficiency, in whom severe carnitine deficiency was apparent. In all 3, long-term carnitine treatment proved to be vital and eliminated most of the symptoms.
