Abstract |
The metabolic disturbances of Reye’s syndrome are many and involve carbohydrates, amino acids,
free fatty acids, proteins, ammonia and acid-base balance. It has been suggested that the derangement
of mitochondrial integrity by an agent or agents unknown leads to a loss of enzyme activity in many
metabolic pathways in which t노e mitochondria are involoved. Of primary interests in this study is the
abnormalities regarding amino acids which have been described as unique.
Plasma amino acid concentrations were measured quantitatively in seven children with Reye’s
syndrome, then compared with those in three healthy chidren, three patients suffering from acute
hepatitis and five patients reported by Romshe et al. as Reye-like illnesses. (Fructose intolerance,
ornithine transcarbamylase deficiency, systemic carnitine deficiency)
The salient feature of plasma amino acid concentrations in Reye’s syndrome is significant increase
in the mean concentrations of threonine, glutamate and alanine (54.6 ug/dl, 16.7 ug/dl, 89.6 ug/dl
respectively), although there are wide variations among patients. Plasma amino acid patterns in
Reye’s syndrome seems to be similar to those in ornithine transcarbamylase deficiency. |
