Abstract

We report a case of stroke in a child with acquired protein C deficiency receiving valproic acid (VPA). To investigate the possible association of VPA with protein C deficiency, protein C levels were measured in 20 children receiving VPA monotherapy and 20 children receiving other anticonvulsants. Protein C levels were reduced in up to 45% of the VPA-treated subjects.
