Abstract
Objectives: To determine the prevalence of epilepsy in Saudi pregnant women and estimate the frequency of seizure types in suffering individuals using different anti-epileptic drug modalities. It also aimed to report the teratogenic effects of anti-epileptic drugs as observed in neonates.
Methods: This prospective study was conducted at King Fahd University Hospital from June 2018 to July 2019. Sixty-eight pregnant women diagnosed with epilepsy were included in this study. Seizure types and their frequencies were recorded along with anti-epileptic drug therapies and their association with fetal/neonatal malformations.
Results: Out of 68 epileptic pregnant females, 30 (44.1%) experienced focal seizures and 38 (55.9%) experienced generalized seizures. Thirty-nine (57.3%) received monotherapy, 21 (30.9%) received polytherapy and 8 (11.8%) did not take antiepileptic drugs during pregnancy. Thirty-six (52.9%) patients experienced no change in seizure frequency during pregnancy, 19 (27.9%) experienced increase in seizure frequency and 13 (19.1%) showed decreased seizure frequency. The pregnancy outcomes analysis showed 2 (2.9%) intrauterine fetal deaths, whereas 4 (4.9%) neonates showed facial and/or organ malformations.
Conclusion: The frequency of seizures was found to increase in only 27.9% of the pregnant women in the sample. Malformation and mortality rates were higher in fetuses/neonates of patients with generalized seizures. It was observed that for the patient group using monotherapy, the rate of healthy babies was higher than that of the group using polytherapy.
