Abstract

Summary: Purpose: To quantify the risks of intrauterine antiepileptic drug (AED) exposure in monotherapy and poly‐therapy. Methods : Data from five prospective European studies totaling 1,379 children were pooled and reanalyzed. Data were available for 1,221 children exposed to AED during pregnancy and for 158 children of unexposed control pregnancies. Results : Overall, when comparing a subgroup of 192 children exposed to AED with 158 children of matched nonepileptic controls, there was an increased risk of major congenital malformations (MCA) in children exposed to AED during gestation [relative risk (RR) 2.3; 95% confidence interval (CI): 1.2–4.7]. A significant increase in risk was found for children exposed to valproate (VPA) (RR 4.9; 95% CI: 1.6–15.0) or carbamazepine (CBZ) (RR 4.9; 95% CI: 1.3–18.0) in monotherapy. When comparing different AED regimens during all 1,221 pregnancies, risks of MCA were significantly increased for the combination of phenobarbital (PB) and ethosuximide (RR 9.8; 95% CI: 1.4–67.3) and the combination of phenytoin, PB, CBZ, and VPA (RR 11.0; 95% CI: 2.1–57.6). Offspring of mothers using > 1,000 mg VPNday were at a significantly increased risk of MCA, especially neural tube defects, compared to offspring exposed ≥600 mg VPNday (RR 6.8; 95% CI: 1.4–32.7). No difference in risk of MCA was found between the offspring exposed to 601–1,000 mg/day and ≥600 mg/day. Conclusions : This reanalysis shows that VPA is consistently associated with an increased risk of MCA in babies born to mothers with epilepsy. Significant associations were also observed with CBZ. Larger prospective population‐based studies are needed to evaluate the risks of many other less frequently prescribed treatment regimens, including newly marketed AEDs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
