OBJECTIVE: To study the effect of folic acid-containing multivitamin supplementation in epileptic women before and during pregnancy in order to determine the rate of structural birth defects and epilepsy-related side effects.
STUDY DESIGN: First a randomised trial, later periconception care including in total 12225 females.
RESULTS: Of 60 epileptic women with periconceptional folic acid (0.8 mg)-containing multivitamin supplementation, no one developed epilepsy-related side effects during the periconception period. One epileptic woman delivered a newborn with cleft lip and palate. Another patient exhibited with a cluster of seizures after the periconception period using another multivitamin. This 22-year-old epileptic woman was treated continuously by carbamazepine and a folic acid (1 mg)-containing multivitamin from the 20th week of gestation. She developed status epilepticus and later symptoms of systemic lupus erythematodes. Her pregnancy ended with stillbirth.
CONCLUSIONS: The epileptic pregnant patient's autoimmune disease (probably drug-induced lupus) could damage the blood-brain barrier, therefore the therapeutic dose (> or =1 mg) of folic acid triggered a cluster of seizures. Physiological dose (<1 mg) of folic acid both in healthy and 60 epileptic women, all without any autoimmune disease, did not increase the risk for epileptic seizures.
