Hydroxykynurenine/hydroxyanthranilic acid ratios and febrile convulsions.

Abstract

Hydroxykynurenine/hydroxyanthranilic acid ratios were measured in children with febrile convulsions, afebrile fits, and fever, as well as in healthy controls. Increased ratios were found not only in the children who had fits but also in the children who were febrile and did not have fits. It is suggested that a raised hydroxykynurenine/hydroxyanthranilic acid ratio does not necessarily indicate vitamin B6 deficiency but may represent a nonspecific response of tryptophan metabolism to stress.
