Valproic Acid Monotherapy in Pregnancy and Major Congenital Malformations

TLDR
The use of valproic acid monotherapy in the first trimester of pregnancy was associated with significantly increased risks of several congenital malformations, as compared with no use of antiepileptic drugs or with use of other antiespecific drugs.
Abstract
Background The use of valproic acid in the first trimester of pregnancy is associated with an increased risk of spina bifida, but data on the risks of other congenital malformations are limited. Methods We first combined data from eight published cohort studies (1565 pregnancies in which the women were exposed to valproic acid, among which 118 major malformations were observed) and identified 14 malformations that were significantly more common among the offspring of women who had received valproic acid during the first trimester. We then assessed the associations between use of valproic acid during the first trimester and these 14 malformations by performing a case–control study with the use of the European Surveillance of Congenital Anomalies (EUROCAT) antiepileptic-study database, which is derived from population-based congenital-anomaly registries. Registrations (i.e., pregnancy outcomes with malformations included in EUROCAT) with any of these 14 malformations were compared with two control groups, o...

Prenatal valproate exposure and risk of autism spectrum disorders and childhood autism.

TL;DR: Maternal use of valproate during pregnancy was associated with a significantly increased risk of autism spectrum disorder and childhood autism in the offspring, even after adjusting for maternal epilepsy.

Malformation risks of antiepileptic drugs in pregnancy: a prospective study from the UK Epilepsy and Pregnancy Register

TL;DR: Only 4.2% of live births to women with epilepsy had an MCM, and polytherapy exposure was greater than for monotherapy exposure, and carbamazepine was associated with the lowest risk of MCM.

Cognitive Function at 3 Years of Age after Fetal Exposure to Antiepileptic Drugs

TL;DR: In utero exposure to valproate, as compared with other commonly used antiepileptic drugs, is associated with an increased risk of impaired cognitive function at 3 years of age, and this finding supports a recommendation thatValproate not be used as a first-choice drug in women of childbearing potential.

Maternal use of antiepileptic drugs and the risk of major congenital malformations : A joint European prospective study of human teratogenesis associated with maternal epilepsy

TL;DR: The objective was to quantify the risks of intrauterine antiepileptic drug (AED) exposure in monotherapy and poly‐therapy and to assess the importance of knowing the carrier and removal status of these drugs.

Practice parameter update: management issues for women with epilepsy - focus on pregnancy (an evidence-based review): teratogenesis and perinatal outcomes. Report of the Quality Standards Subcommittee and Therapeutics and Technology Assessment Subcommittee of the American Academy of Neurology and American Epilepsy Society

TL;DR: Reassessment of evidence for management issues related to the care of women with epilepsy (WWE) during pregnancy finds it highly probable that intrauterine first-trimester valproate (VPA) exposure has higher risk of major congenital malformations (MCMs) compared to carbamazepine and possible compared to phenytoin or lamotrigine.
