[Deficiency in medium chain acyl coA dehydrogenase manifested as febrile coma].
A 21-month-old infant developed coma with hypotonia during a viral infection. Acyl CoA dehydrogenase deficiency was diagnosed on the basis of results of the chromatographic study of organic acids performed on a urine specimen collected during the acute episode. However, other disorders of mitochondrial and fatty acid oxygenation can generate similar symptoms. Emphasis is put on the need for collecting urine specimens in patients who develop alterations in consciousness and hypoglycemia without ketonuria during prolonged fasting or repeated vomiting due to a viral infection. Urine chromatography can suggest which enzyme is defective, although the diagnosis should always be confirmed by a study of fatty acid oxygenation in lymphocytes or fibroblasts.
