title: Early effect of sodium valproate and carbamazepine monotherapy on homocysteine metabolism in children with epilepsy.
abstract: Plasma total homocysteine (p-tHcy), serum folate (s-F), serum vitamin B-12 (s-B12) and plasma pyridoxal-5'-phosphate (p-PLP) were measured in epileptic children before and after a 20-week period of sodium valproate (group A, n=32) and carbamazepine (group B, n=20) monotherapy. P-tHcy significantly increased in both groups, s-F and s-B12 significantly increased in group A, while s-F and p-PLP significantly decreased in group B. Our study showed an early effect of antiepileptic drug treatment on homocysteine metabolism.
