Abstract

Morphometric analysis of liver ultrastructure in 14 children with Reye's syndrome (RS) of varying morphologic severity was compared with that of 6 children with normal livers. Results showed reduced numbers of enlarged mitochondria in RS. Multivariant analysis identified correlations between increased mitochondrial size, decreased mitochondrial number, and severity of neurologic disease (stage). A disproportionate increase in mitochondrial area and perimeter in the RS cases with the most depressed mitochondrial number distinguished the 4 children with residual neurologic damage or death. Serum salicylate concentrations were negatively correlated with severity of morphologic alteration. Two cases of non-RS salicylate toxicity showed normal or near-normal mitochondrial size and number. In fatty liver from an autopsy specimen from a child, a child with carnitine deficiency, and a child on therapy for dermatomyositis, mitochondrial numbers were also normal. Decreased mitochondrial numbers are characteristic of RS and imply a pathophysiologic mechanism, possibly related to impaired mitochondrial replication. Synergism with other forms of mitochondrial injury, such as salicylates, hypoglycemia, or shock may influence clinical severity, progression, and outcome.
