Abstract
OBJECTIVE Although early evidence shows that epilepsy can increase the risks of adverse pregnancy, some outcomes are still debatable. We performed a systematic review and meta-analysis to explore the effects of maternal and fetal adverse outcomes in pregnant women with epilepsy. METHODS PubMed, Embase, Cochrane, and Web of Science were employed to collect studies that investigated the potential risk of obstetric complications during the antenatal, intrapartum, or postnatal period, as well as any neonatal complications. The search was conducted from inception to November 16, 2022. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the included original studies. The odds ratio (OR) values were extracted after adjusting for confounders to measure the relationship between pregnant women with epilepsy and adverse maternal or fetal outcomes. The protocol for this systematic review is registered with PROSPERO ID CRD42023391539. RESULTS Of 35 articles identified, there were 142,577 mothers with epilepsy and 34,381,373 mothers without epilepsy. Our study revealed a significant association between pregnant women with epilepsy (PWWE) and the incidence of cesarean section, preeclampsia/eclampsia, gestational hypertension, induction of labor, gestational diabetes and postpartum hemorrhage compared with those without epilepsy. Regarding newborns outcomes, PWWE versus those without epilepsy had increased odds of preterm birth, small for gestational age, low birth weight (<2500 g), and congenital malformations, fetal distress. The odds of operative vaginal delivery, newborn mortality, and Apgar (≤ 7) were similar between PWWE and healthy women. CONCLUSION Pregnant women affected by epilepsy encounter a higher risk of adverse obstetric outcomes and fetal complications. Therefore, it is crucial to develop appropriate prevention and intervention strategies prior to or during pregnancy to minimize the negative impacts of epilepsy on maternal and fetal health.

Abstract
Results from studies investigating the association between maternal or child epilepsy, use of anticonvulsants in pregnancy, and childhood cancer are inconsistent and at times contradictory. Linking Danish national databases, we obtained epilepsy and childhood cancer diagnoses, and anticonvulsant use data. We estimated adjusted odds ratios of all or specific childhood cancers in relation to maternal or child epilepsy and anticonvulsant therapies using conditional logistic regression. Maternal epilepsy was positively associated with all childhood cancers in offspring, specifically, with acute lymphoblastic leukemia (Odds Ratio (OR) = 1.68, 95% Confidence Interval (CI) = 1.16, 2.43) and Wilms tumor (OR = 2.13, 95% CI = 0.97, 4.68). When considering maternal ever (lifetime) ingestion of anticonvulsants, a positive association was found with all cancers (OR = 1.14, 95% CI = 1.00, 1.30), and central nervous system tumors (CNS) (OR = 1.36, 95% CI = 1.04, 1.76) as well as neuroblastoma (OR = 1.76, 95% CI = 1.06, 2.90) among offspring. Maternal anticonvulsant use before or during the index pregnancy was related to CNS tumors in offspring (OR = 1.99, 95% CI = 0.99, 4.00).

[PMID: 39002279 DOI: 10.1016/j.yebeh.2024.109937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 07/01/2024] [Accepted: 07/02/2024] [Indexed: 07/15/2024]
Abstract
INTRODUCTION Epilepsy is a disease that affects a significant proportion of the female population worldwide. The management of anti-seizure medications during pregnancy and the potential adverse outcomes to both the mother and fetus represent a significant challenge. This retrospective study aimed to evaluate the impact of anti-seizure medications during pregnancy by comparing maternal and fetal outcomes between pregnant women with and without epilepsy. METHODS A total of 242 participants were analysed, including 112 with epilepsy and 130 healthy pregnant controls. Maternal age, medical history, seizure characteristics, use of anti-seizure medications, and pregnancy history were recorded. Maternal and fetal complications, delivery modes, and perinatal outcomes were evaluated. RESULTS A total of 242 patients, including 112 (46.3 %) pregnant women with epilepsy and 130 (53.7 %) healthy pregnant women, were included in the study. Among pregnant patients with epilepsy, 4 (3.5 %) did not use anti-seizure medications, 79 (70.5 %) received monotherapy, and 29 (25.8 %) received polytherapy. The rates of pregnancy termination, spontaneous abortion, and maternal and fetal complications were significantly higher in pregnant women with epilepsy (p = 0.045, p = 0.045, p < 0.001, and p = 0.016, respectively). Folic acid use, planned pregnancy rate and postpartum breastfeeding rate were all statistically lower in pregnant women with epilepsy (p < 0.001, p < 0.001, p < 0.001, respectively). The rates of intensive care unit stay, infants with birth weight less than 2500 g, congenital malformations, and preterm births were significantly higher in babies born to pregnant women with epilepsy (p < 0.001, p = 0.047, p = 0.003, and p = 0.051, respectively). Gestational diabetes mellitus was observed in 4 (13.8 %) and congenital malformations in 4 (14.3 %) of the pregnant women with epilepsy who received polytherapy, and in both cases these rates were statistically higher than those of pregnant women with epilepsy who received monotherapy (p = 0.048 and p = 0.004, respectively). DISCUSSION This study demonstrated that pregnancies among women affected by epilepsy have significantly higher rates of maternal and fetal complications, spontaneous abortions, and premature births. Polytherapy with anti-seizure medications is associated with an increased risk of gestational diabetes and congenital anomalies. Notably, folic acid use, planned pregnancy, and postpartum breastfeeding were less common in patients with epilepsy. The most commonly prescribed anti-seizure medications were levetiracetam and lamotrigine. Caesarean section is a common mode of delivery in pregnancies of mothers with epilepsy. CONCLUSION These results suggest that epilepsy increases both maternal and fetal complications during pregnancy. Furthermore, the use of anti-seizure medications appears to have a significant impact on pregnancy outcomes. Our findings highlight the need for comprehensive management strategies and informed decision making to reduce risks and optimise maternal and fetal outcomes among women with epilepsy.

Abstract
OBJECTIVE This study was undertaken to examine the association between different patterns of antiseizure medication (ASM) use during pregnancy and adverse obstetric outcomes (preterm birth, low birth weight [LBW], and small for gestational age [SGA]). METHODS This retrospective cohort study used the Birth Certificate Application and National Health Insurance data in Taiwan (January 1, 2004 through December 31, 2018). We retrieved weekly ASM among pregnant women with epilepsy who were prepregnancy chronic users and used group-based trajectory modeling to identify distinct patterns of use. Logistic regressions were adopted to examine the association between patterns of ASM use and risk of preterm birth, LBW, and SGA. In addition, we revealed postnatal ASM utilization pattern among these prepregnancy chronic users as an exploratory study. RESULTS Of 2175 pregnant women with epilepsy, we identified four patterns of ASM use during pregnancy: frequent and continuous (64.87%), frequent but discontinuous (7.08%), intermittent (19.72%), and intermittent and discontinuous users (8.32%). Compared to frequent and continuous users, the adjusted odds ratios for preterm birth in frequent but discontinuous, intermittent, and intermittent and discontinuous users were .83 (95% confidence interval [CI] = .47-1.48), .71 (95% CI = .47-1.05), and .88 (95% CI = .52-1.49), respectively. Similar results were observed for LBW and SGA. In the exploratory study, we found that most of our study subjects maintained the same patterns before and after delivery. SIGNIFICANCE After considering duration and timing of exposure, our study did not find an association between four distinct patterns of ASM use and adverse obstetric outcomes among women with epilepsy. The findings suggested that optimal seizure control could be received for pregnant women with epilepsy after evaluating the risks and benefits.

Teratogenesis, Perinatal, and Neurodevelopmental Outcomes After In Utero Exposure to Antiseizure Medication: Practice Guideline From the AAN, AES, and SMFM. Neurology 2024; 102:e209279.

Abstract
This practice guideline provides updated evidence-based conclusions and recommendations regarding the effects of antiseizure medications (ASMs) and folic acid supplementation on the prevalence of major congenital malformations (MCMs), adverse perinatal outcomes, and neurodevelopmental outcomes in children born to people with epilepsy of childbearing potential (PWECP). A multidisciplinary panel conducted a systematic review and developed practice recommendations following the process outlined in the 2017 edition of the American Academy of Neurology Clinical Practice Guideline Process Manual. The systematic review includes studies through August 2022. Recommendations are supported by structured rationales that integrate evidence from the systematic review, related evidence, principles of care, and inferences from evidence. The following are some of the major recommendations. When treating PWECP, clinicians should recommend ASMs and doses that optimize both seizure control and fetal outcomes should pregnancy occur, at the earliest possible opportunity preconceptionally. Clinicians must minimize the occurrence of convulsive seizures in PWECP during pregnancy to minimize potential risks to the birth parent and to the fetus. Once a PWECP is already pregnant, clinicians should exercise caution in attempting to remove or replace an ASM that is effective in controlling generalized tonic-clonic or focal-to-bilateral tonic-clonic seizures. Clinicians must consider using lamotrigine, levetiracetam, or oxcarbazepine in PWECP when appropriate based on the patient's epilepsy syndrome, likelihood of achieving seizure control, and comorbidities, to minimize the risk of MCMs. Clinicians must avoid the use of valproic acid in PWECP to minimize the risk of MCMs or neural tube defects (NTDs), if clinically feasible. Clinicians should avoid the use of valproic acid or topiramate in PWECP to minimize the risk of offspring being born small for gestational age, if clinically feasible. To reduce the risk of poor neurodevelopmental outcomes, including autism spectrum disorder and lower IQ, in children born to PWECP, clinicians must avoid the use of valproic acid in PWECP, if clinically feasible. Clinicians should prescribe at least 0.4 mg of folic acid supplementation daily preconceptionally and during pregnancy to any PWECP treated with an ASM to decrease the risk of NTDs and possibly improve neurodevelopmental outcomes in the offspring.

Abstract
Seizure aggravation in women with epilepsy (WWE) tends to occur at two specific times during the menstrual cycle: the perimenstrual phase and the ovulation period. Antiseizure drugs (ASDs), especially those that induce enzymes, can accelerate the metabolism of hormones in oral contraceptives, rendering them less effective. Estrogen in contraceptive pills increases the metabolism of lamotrigine. Physiological changes during pregnancy can significantly impact the pharmacokinetics of ASDs, potentially necessitating adjustments in dosage for women with epilepsy to maintain seizure control. The use of valproate in pregnant women is associated with the highest risk of major congenital malformations among ASDs. Risks of major congenital malformations associated with lamotrigine, levetiracetam, and oxcarbazepine were within the range reported in the general population. Exposure to valproate can lead to lower IQ in offspring. Reduced folic acid levels are linked to orofacial clefts, cardiovascular malformations, and urogenital and limb anomalies in WWE. Decreased folate levels are expected with the use of enzyme-inducing ASDs. However, a high dose of folate was associated with an increased risk of cancer in children of mothers with epilepsy. Most ASDs are generally considered safe for breastfeeding and should be encouraged. However, no single ASD is considered ideal for childbearing WWE. Lamotrigine and levetiracetam are relatively more suitable options for this situation.

Abstract
BACKGROUND Prenatal exposure to certain anti-seizure medications (ASMs) is associated with an increased risk of major congenital malformations (MCM). The majority of women with epilepsy continue taking ASMs throughout pregnancy and, therefore, information on the potential risks associated with ASM treatment is required. OBJECTIVES To assess the effects of prenatal exposure to ASMs on the prevalence of MCM in the child. SEARCH METHODS For the latest update of this review, we searched the following databases on 17 February 2022: Cochrane Register of Studies (CRS Web), MEDLINE (Ovid, 1946 to February 16, 2022), SCOPUS (1823 onwards), and ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP). No language restrictions were imposed. SELECTION CRITERIA We included prospective cohort controlled studies, cohort studies set within pregnancy registries, randomised controlled trials and epidemiological studies using routine health record data. Participants were women with epilepsy taking ASMs; the two control groups were women without epilepsy and untreated women with epilepsy. DATA COLLECTION AND ANALYSIS Five authors independently selected studies for inclusion. Eight authors completed data extraction and/or risk of bias assessments. The primary outcome was the presence of an MCM. Secondary outcomes included specific types of MCM. Where meta-analysis was not possible, we reviewed included studies narratively. MAIN RESULTS From 12,296 abstracts, we reviewed 283 full-text publications which identified 49 studies with 128 publications between them. Data from ASM-exposed pregnancies were more numerous for prospective cohort studies (n = 17,963), than data currently available for epidemiological health record studies (n = 7913). The MCM risk for children of women without epilepsy was 2.1% (95% CI 1.5 to 3.0) in cohort studies and 3.3% (95% CI 1.5 to 7.1) in health record studies. The known risk associated with sodium valproate exposure was clear across comparisons with a pooled prevalence of 9.8% (95% CI 8.1 to 11.9) from cohort data and 9.7% (95% CI 7.1 to 13.4) from routine health record studies. This was elevated across almost all comparisons to other monotherapy ASMs, with the absolute risk differences ranging from 5% to 9%. Multiple studies found that the MCM risk is dose-dependent. Children exposed to carbamazepine had an increased MCM prevalence in both cohort studies (4.7%, 95% CI 3.7 to 5.9) and routine health record studies (4.0%, 95% CI 2.9 to 5.4) which was significantly higher than that for the children born to women without epilepsy for both cohort (RR 2.30, 95% CI 1.47 to 3.59) and routine health record studies (RR 1.14, 95% CI 0.80 to 1.64); with similar significant results in comparison to the children of women with untreated epilepsy for both cohort studies (RR 1.44, 95% CI 1.05 to 1.96) and routine health record studies (RR 1.42, 95% CI 1.10 to 1.83). For phenobarbital exposure, the prevalence was 6.3% (95% CI 4.8 to 8.3) and 8.8% (95% CI 0.0 to 9277.0) from cohort and routine health record data, respectively. This increased risk was significant in comparison to the children of women without epilepsy (RR 3.22, 95% CI 1.84 to 5.65) and those born to women with untreated epilepsy (RR 1.64, 95% CI 0.94 to 2.83) in cohort studies; data from routine health record studies was limited. For phenytoin exposure, the prevalence of MCM was elevated for cohort study data (5.4%, 95% CI 3.6 to 8.1) and routine health record data (6.8%, 95% CI 0.1 to 701.2). The prevalence of MCM was higher for phenytoin-exposed children in comparison to children of women without epilepsy (RR 3.81, 95% CI 1.91 to 7.57) and the children of women with untreated epilepsy (RR 2.01. 95% CI 1.29 to 3.12); there were no data from routine health record studies. Pooled data from cohort studies indicated a significantly increased MCM risk for children exposed to lamotrigine in comparison to children born to women without epilepsy (RR 1.99, 95% CI 1.16 to 3.39); with a risk difference (RD) indicating a 1% increased risk of MCM (RD 0.01. 95% CI 0.00 to 0.03). This was not replicated in the comparison to the children of women with untreated epilepsy (RR 1.04, 95% CI 0.66 to 1.63), which contained the largest group of lamotrigine-exposed children (> 2700). Further, a non-significant difference was also found both in comparison to the children of women without epilepsy (RR 1.19, 95% CI 0.86 to 1.64) and children born to women with untreated epilepsy (RR 1.00, 95% CI 0.79 to 1.28) from routine data studies. For levetiracetam exposure, pooled data provided similar risk ratios to women without epilepsy in cohort (RR 2.20, 95% CI 0.98 to 4.93) and routine health record studies (RR 0.67, 95% CI 0.17 to 2.66). This was supported by the pooled results from both cohort (RR 0.71, 95% CI 0.39 to 1.28) and routine health record studies (RR 0.82, 95% CI 0.39 to 1.71) when comparisons were made to the offspring of women with untreated epilepsy. For topiramate, the prevalence of MCM was 3.9% (95% CI 2.3 to 6.5) from cohort study data and 4.1% (0.0 to 27,050.1) from routine health record studies. Risk ratios were significantly higher for children exposed to topiramate in comparison to the children of women without epilepsy in cohort studies (RR 4.07, 95% CI 1.64 to 10.14) but not in a smaller comparison to the children of women with untreated epilepsy (RR 1.37, 95% CI 0.57 to 3.27); few data are currently available from routine health record studies. Exposure in utero to topiramate was also associated with significantly higher RRs in comparison to other ASMs for oro-facial clefts. Data for all other ASMs were extremely limited. Given the observational designs, all studies were at high risk of certain biases, but the biases observed across primary data collection studies and secondary use of routine health records were different and were, in part, complementary. Biases were balanced across the ASMs investigated, and it is unlikely that the differential results observed across the ASMs are solely explained by these biases. AUTHORS' CONCLUSIONS Exposure in the womb to certain ASMs was associated with an increased risk of certain MCMs which, for many, is dose-dependent.

Pregnancy characteristics and adverse outcomes in offspring of women with epilepsy: a prospective registry study from Mainland China. Front Neurol 2023; 14:1195003. [PMID: 37638195 PMCID: PMC10455922 DOI: 10.3389/fneur.2023.1195003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 07/24/2023] [Indexed: 08/29/2023] Open
Abstract
Objective This study aimed to explore the influencing factors of adverse outcomes in the offspring of women with epilepsy (WWE) and to analyze the changes brought about by the epilepsy knowledge popularization campaign in China (EKPCIC). Methods This nested case-control study focused on WWE and their offspring from a female epilepsy cohort in mainland China. From January 2009 to August 2022, WWE was prospectively enrolled in 32 study centers. This study aimed to observe the health outcomes of their offspring within 1 year of age. The main outcome measure assessed the health status of the offspring within their first year of age. We aimed to analyze the effects of seizures, anti-seizure medicines (ASMs), and a lack of folic acid supplementation on adverse outcomes in the offspring of WWE and to explore the changes in perinatal management and adverse outcomes of the offspring after dissemination of the EKPCIC in 2015. Additionally, subgroup analyses were conducted to compare seizure control during pregnancy between the valproate and non-valproate groups. Results In total, 781 pregnancies in 695 WWE were included, of which 186 (23.69%) had adverse outcomes. The National Hospital Epilepsy Severity Scale score, number of seizures, status epilepticus, ASM type, and valproate and folic acid doses were associated with a high risk of adverse outcomes. After the EKPCIC, the use of ASMs (P = 0.013) and folic acid (P < 0.001), the seizure-free rate during pregnancy (P = 0.013), and the breastfeeding rate (P < 0.001) increased, whereas the incidence of complications during pregnancy decreased (P = 0.013). However, there was no significant difference in the incidence of adverse outcomes between the analyzed offspring pre-/post-EKPCIC. Additionally, there was no association between the frequency of seizures at different time points during pregnancy and the use of valproate (F = 1.514, P = 0.221). Conclusion Possible factors influencing adverse outcomes in the offspring of WWE include seizures, type and number of ASM usage, and a lack of folic acid supplementation. Although the management of WWE during pregnancy is now more standardized, further efforts are needed to reduce adverse outcomes in offspring.

Abstract
Objective Results from studies investigating the association between maternal or child epilepsy, use of anticonvulsants in pregnancy, and childhood cancer are inconsistent and at times contradictory. Methods Linking Danish national databases, we obtained epilepsy and childhood cancer diagnoses, and anticonvulsant use data. We estimated adjusted odds ratios of all or specific childhood cancers in relation to maternal or child epilepsy and anticonvulsant therapies using conditional logistic regression. Results Maternal epilepsy was positively associated with all childhood cancers in offspring, specifically, with acute lymphoblastic leukemia (Odds Ratio (OR) = 1.68, 95% Confidence Interval (CI) = 1.16, 2.43) and Wilms tumor (OR = 2.13, 95%CI = 0.97, 4.68). When considering maternal ever (lifetime) ingestion of anticonvulsants, a positive association was found with all cancers (OR = 1.15, 95%CI = 1.01, 1.31), and central nervous system tumors (OR = 1.32, 95%CI = 1.03, 1.69) as well as neuroblastoma (OR = 2.05, 95%CI = 1.29, 3.28) among offspring. Maternal anticonvulsant use before or during the index pregnancy was related to CNS tumors in offspring (OR = 1.78, 95%CI = 0.99, 3.21), however the confidence interval included the null. Significance Maternal use of certain anticonvulsant medications may be a risk factor for cancer in offspring. Medical providers may need to consider what type of treatments to prescribe to pregnant mothers with epilepsy.

Morbidity and rehospitalization postpartum among women with epilepsy and their infants: A population-based study. Epilepsy Behav 2022; 136:108943. [PMID: 36252288 DOI: 10.1016/j.yebeh.2022.108943] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 09/15/2022] [Accepted: 09/29/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVE We compared the relative occurrence of selected pregnancy outcomes and postpartum rehospitalizations among women with and without epilepsy and their infants. Using linked vital-hospital discharge records of women with deliveries in Washington State 1987-2014, comparisons were made overall, by epilepsy type, and by time periods related to antiepileptic drug (AED) marketing changes. METHODS This population-based retrospective cohort study identified women with, and without epilepsy per diagnosis codes in the hospital discharge record from among all deliveries during 1987-2014 to examine maternal and infant outcomes, rehospitalization and mortality <2 years postpartum. Relative risks (RRs) and 95 % confidence intervals (CI) overall, and by epilepsy type were calculated using Poisson regression. We assessed the validity of epilepsy identification based on diagnosis codes by conducting a medical chart review for a sample of women. RESULTS Women with epilepsy had increased risks of preeclampsia (RR 1.23; 95 % CI 1.08-1.41) and gestational diabetes (RR 1.18; 95 % CI 1.02-1.36). Their infants had increased malformation (RR 1.23; 95 % C: 1.08-1.42) and small for gestational age (SGA, RR 1.39; 95 % CI 1.25-1.54) risks, and were nearly three times as likely to not be breastfed. Affected mothers (RR 5.25; 95 % CI 2.46-11.23) and their infants (RR 1.64, 95 % CI 1.41-1.89) required more ICU admissions during the delivery hospitalizations, and more postpartum rehospitalization, with greatest risk in the first six months. Maternal mortality < 2 years after delivery was increased (RR 7.11; 95 % CI 2.47-20.49). Increased risks were observed for all epilepsy subtypes for nearly all outcomes examined. Risks of preterm delivery and low birthweight increased over time (p <.05). Suggestive, but not statistically significant temporal decreases in risks of gestational diabetes and malformations and increased risk of preterm labor were noted. We observed high sensitivity of diagnosis codes for identifying pregnant women with epilepsy. CONCLUSION These population-based results emphasize the need for frequent postpartum monitoring of women with epilepsy. Increases in risks of low birthweight and preterm delivery over time are of concern. Possible temporal changes in other outcomes warrant further investigation.

Abstract
Sex and gender differences in epilepsy are important influencing factors in epilepsy care. In epilepsy, the hormonal differences between the sexes are important as they impact specific treatment considerations for patients at various life stages particularly during early adulthood with establishment of the menstrual cycle, pregnancy, perimenopause and menopause. Choice of antiseizure medication may have direct consequences on hormonal cycles, hormonal contraception, pregnancy and fetal risk of major congenital malformation. Conversely hormones whether intrinsic or extrinsically administered may have direct impact on antiseizure medications and seizure control. This chapter explores these important influences on the management of persons with epilepsy.

The Rate of and Factors Associated with Delivery by Caesarean Section among Women with Epilepsy: Time Trend in a Single-Centre Cohort in Mazovia, Poland. J Clin Med 2022; 11:jcm11092622. [PMID: 35566748 PMCID: PMC9104823 DOI: 10.3390/jcm11092622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2022] [Revised: 04/27/2022] [Accepted: 05/04/2022] [Indexed: 02/04/2023] Open
Abstract
Data from literature suggest that the rate of caesarean section (CS) in women with epilepsy (WWE) is higher than in the general population. In Poland, there is neither a national registry nor another data set to access the outcome of pregnancy in WWE. Therefore, we address this gap by prospectively studying CS rates among 1021 WWE pregnancies at a single centre, their trends over time, and factors increasing the likelihood of the CS. To determine whether the diagnosis of epilepsy itself increased this likelihood, mixed models were used to analyse the contributions of specific variables, including the presence of seizures at different pregnancy-related timepoints. Over 20 years, the mean rate of CS in WWE was progressively growing and was higher than in the general population in Mazovia (47% vs. 32%). Generalized seizures in the third trimester increased the likelihood of CS with the highest odds (OR 4.4). The most frequent indication for a CS was obstetric (58.1%), followed by epilepsy-related (25.2%). Almost half of women who indicated epilepsy as the sole reason for CS had no seizure during pregnancy, and nearly 70% did not have generalized seizures. This suggests the overuse of epilepsy as an indication of CS and encourages defining more strict criteria.

Abstract
Objective We examined how maternal epilepsy and use of antiseizure medications in pregnancy was associated with offspring mortality. Methods This population‐based cohort study included all live‐ and stillborn singletons in Denmark between 1981 and 2016. We used nation‐wide registers to retrieve information on pregnancy characteristics, epilepsy diagnoses, use of antiseizure medications, and mortality. Adjusted mortality rate ratios (MRR) were estimated using log‐linear Poisson regression. Results The cohort consisted of 1,862,474 children. In total, 12,026 live‐born children died during follow‐up, of whom 170 (1.4%) were offspring of mothers with epilepsy. Overall mortality was increased in offspring of mothers with epilepsy compared to offspring of mothers without epilepsy (MRR = 1.46, 95% CI: 1.23–1.71), driven by an excess mortality only in the first year of life. Mortality was increased for natural deaths (MRR = 1.50, 95% CI: 1.25–1.78) but not from unnatural deaths (MRR = 1.38, 95% CI: 0.84–2.14), and only in offspring of women with epilepsy who used antiseizure medications during pregnancy (MRR = 1.51, 95% CI: 1.00–2.17), but not in offspring of women with epilepsy who did not use antiseizure medications while pregnant (MRR = 0.97, 95% CI: 0.69–1.31). When analyses were restricted to children born from 2000 and onwards, the excess mortality that was observed in the first year of life among children of mothers with epilepsy, was no longer evident. Interpretation During the 1981 to 1999 epoch, offspring of women with epilepsy were at increased risk of dying in the first year of life. However, this risk did not extend to children born after 2000. Future retrospective studies of the effects of maternal epilepsy on the health of the offspring should take this difference into account. ANN NEUROL 2022;91:455–465

Patterns of antiseizure medication prescription in pregnancy and maternal complications in women with epilepsy: A retrospective study in Saudi Arabia. Saudi Pharm J 2022; 30:205-211.

Abstract
Aim To evaluate patterns of antiseizure medication (ASM) prescription in pregnancy and changes over a 16-year period: 2005–2020, and to investigate maternal complications in pregnant women with epilepsy (WWE). Method Data of pregnant WWE was retrospectively reviewed at the King Faisal Specialist Hospital and Research Centre, Riyadh and Jeddah, Saudi Arabia. Results Out of 162 pregnancies, 81.5% were prescribed ASMs. During the study period, the prescription rate increased from 68.8% to 93.5%. Between 2005 and 2020, the use of new ASMs increased from 15.4% to 75.5% (p < 0.0001). Furthermore, valproate use markedly decreased from 23.08% to 2.04%. The rate of maternal and delivery complications was 29.6%; the most frequent was gestational diabetes (5.6%), followed by bleeding during pregnancy (4.9%). Furthermore, preeclampsia and eclampsia were documented in 3.7% and 1.8%, respectively. ASMs use and other factors were not found to be associated with maternal complications (p > 0.05). However, first generation ASMs, i.e. carbamazepine (38.71%) and valproate (41.67%), were associated with higher maternal complication rates than new ASMs, i.e. levetiracetam (25%) and lamotrigine (20%), but the difference was not statistically significant (p = 0.4403). Conclusion ASM prescription in pregnancy is increasing as is the use of new ASMs. The rate of maternal and delivery complications was relatively low, particularly preeclampsia and eclampsia. ASMs use was not found to associated with these complications. However, exposure to first generation ASMs seemed to be a predictor of adverse pregnancy outcomes.

Abstract
OBJECTIVE Prior research demonstrated large increased risk for maternal mortality among women with epilepsy. The objective of this study was to estimate risk for adverse maternal outcomes during delivery hospitalizations among women with epilepsy. METHODS Truven Health MarketScan databases were used to compare risk for adverse maternal outcomes during delivery hospitalizations based upon whether there was diagnosis of epilepsy and receipt of anti-epileptic drugs prior to delivery. Outcomes included: (i) death during delivery hospitalization, (ii) severe maternal morbidity, (iii) cesarean delivery, (iv) postpartum hemorrhage, (v) placental abruption, (vi) preeclampsia, (vii) preterm delivery, (viii) premature rupture of membranes, and (ix) stillbirth. Adjusted models including hospital and demographic factors were performed with adjusted risk ratios (aRR) with 95% CIs as measures of effect. RESULTS Women with epilepsy prior to delivery who received antiepileptic drugs (n = 6019) during pregnancy were not at increased risk for mortality with no deaths occurring in this group (p = .27). Risk for severe maternal morbidity in this group was approximately double (aRR 2.16, 95% CI 1.86-2.51) with risks for other outcomes including placental abruption (aRR 1.29, 95% CI 1.04-1.60), cesarean delivery (aRR 1.14, 95% CI 1.10-1.18), and preterm delivery (aRR 1.25, 95% CI 1.15-1.35) slightly increased compared to women without seizures. CONCLUSION No significant difference in mortality risk was found for women with epilepsy. Increased risk for other adverse maternal outcomes for women with epilepsy on antiepileptics was modest.

New-onset epilepsy in pregnant women: clinical features and delivery outcomes. Seizure 2020; 81:138-144. [PMID: 32805607 DOI: 10.1016/j.seizure.2020.08.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Revised: 08/04/2020] [Accepted: 08/06/2020] [Indexed: 11/23/2022] Open
Abstract
INTRODUCTION Most seizures during pregnancy occur in women who already have epilepsy. Rarely, some women may have their first seizure during pregnancy. The purpose of this study was to investigate the clinical features and pregnancy outcomes in women with new-onset epilepsy during pregnancy. METHODS 112 pregnant women with epilepsy were prospectively evaluated at the Education - Therapeutic Clinic of the Azerbaijan Medical University, in the neurological and maternity departments of the Clinical Medical Center in Baku over a six-year period. Women were regularly followed by a neurologist and obstetrician till the end of pregnancy. To determine the recurrence of seizures during the pregnancy and after delivery, the women were followed up at least once per three months for a one year period after delivery. Delivery and perinatal outcomes were compared with those of 277 healthy women in the control group (without epilepsy and without registering chronic diseases). RESULTS Of the 112 pregnant women with epilepsy, 12 (10.7%) had their first seizures during the pregnancy: 6 in the 1st, 4 in the 2nd, 2 in the 3rd trimester. Women with new-onset epilepsy had increased risk of cesarean section and perinatal hypoxia in offspring, compared with controls (Odds ratio [OR]: 13.57; 95% confidence interval (CI):2.86-64.31 and OR: 3.61; 95 % CI: 1.06-12.27, respectively). The risks of cesarean section and perinatal hypoxia were not increased in women with new-onset epilepsy compared to women with epilepsy before pregnancy (OR 2.64; 95 % CI 0.54-12.93 and OR 2.18, 95% CI 0.61-7.76, respectively). CONCLUSION In our cohort, women with new-onset epilepsy may have an increased risk of delivery by cesarean section and perinatal hypoxia compared to pregnant controls. The risks were not increased compared to women with epilepsy before pregnancy. Neonatal hypoxia was associated with delivery by cesarean section.

Abstract
PURPOSE Epilepsy is a common neurological disorder that may complicate reproductive health. Our aim in this study was to provide prospective ascertainment of obstetric and neonatal outcomes in women with epilepsy and investigate whether the risk of pregnancy, delivery, and neonatal complications differed between women with epilepsy and women without epilepsy. METHODS Pregnant women with epilepsy and women without epilepsy (control group) were prospectively evaluated during the years 2013-2018. They were regularly followed by a neurologist and obstetrician until the end of pregnancy. RESULTS Delivery and perinatal outcomes were compared between 112 women diagnosed with epilepsy and 277 women without epilepsy. Epilepsy was a significant risk factor for preterm delivery, cesarean section, fetal hypoxia, and Apgar score ≤ 7 at 5 min in offspring (odds ratio (OR) = 2.83, 95% confidence interval (CI) 1.03-7.76; OR = 5.61, 95% CI 3.44-9.14; OR = 1.81, 95% CI 1.08-3.04; OR = 8.12, 95% CI 4.04-16.35, respectively). Seizures during pregnancy had influence on the preference of cesarean section as a mode of delivery (ОR = 3.39; 95% CI 1.40-8.17). The rate of perinatal hypoxia was significantly higher in children born by cesarean section (ОR = 2.84; 95% CI 1.04-7.76). There was no significant difference between women with epilepsy and controls in malformation rate. CONCLUSIONS Women with epilepsy had an increased risk of pregnancy and delivery complications. Cesarean section was associated with an increased risk of complications in offspring.

Abstract
INTRODUCTION Studies have used various epidemiological approaches to study associations between central nervous system (CNS) drug use in pregnancy and CNS outcomes in children. Studies have generally focused on clinical adverse effects, whereas variations in methodologies have not received sufficient attention. OBJECTIVE Our objective was to review the methodological characteristics of existing studies to identify any limitations and recommend further research. METHODS A systematic literature search was conducted on observational studies listed in PubMed from 1 January 1946 to 21 September 2017. Following independent screening and data extraction, we conducted a review addressing the trends of relevant studies, differences between various data sources, and methods used to address bias and confounders; we also conducted statistical analyses. RESULTS In total, 111 observational studies, 25 case-control studies, and 86 cohort studies were included in the review. Publications dating from 1978 to 2006 mainly focused on antiepileptic drugs, but research on antidepressants increased from 2007 onwards. Only one study focused on antipsychotic use during pregnancy. A total of 46 studies obtained data from an administrative database/registry, 20 from ad hoc disease registries, and 41 from ad hoc clinical samples. Most studies (58%) adjusted the confounding factors using general adjustment, whereas only a few studies used advanced methods such as sibling-matched models and propensity score methods; 42 articles used univariate analyses and 69 conducted multivariable regression analyses. CONCLUSION Multiple factors, including different study designs and data sources, have led to inconsistent findings in associations between CNS drug use in pregnancy and CNS outcomes in children. Researchers should allow for study designs with clearly defined exposure periods, at the very least in trimesters, and use advanced confounding adjustment methodology to increase the accuracy of the findings.

Abstract
Many neurologic diseases in women are influenced by the physiologic and hormonal changes of pregnancy, and pregnancy itself poses challenges in both treatment and evaluation of these conditions. Some diseases, such as epilepsy and multiple sclerosis, have a high enough prevalence in the young female population to support robust epidemiologic data while many other neurologic diseases, such as specific myopathies and muscular dystrophies, have a low prevalence, with data limited to case reports and small case series. This chapter features epidemiologic information regarding a breadth of neurologic conditions, including stroke, epilepsy, demyelinating disease, peripheral neuropathies, migraine, sleep-disordered breathing, and meningioma, in women in the preconception, pregnancy, and postpartum stages.

Abstract
PURPOSE To determine the impact of depression, epilepsy and drug abuse during pregnancy on delivery and fetal outcome. Due to the worldwide increasing prevalence of neurological and psychiatric diseases and drug abuse, the number of affected pregnant women is increasing. METHODS A large-scale retrospective case-control analysis of pregnancies affected by depression, epilepsy or drug abuse with and without medication was conducted in two German perinatal centres between 2013 and 2017. The case group consisted of 706 pregnant women who had a diagnosis of depression, epilepsy or drug abuse vs. 12,574 pregnant women without neuropsychiatric diagnosis (control group). The analysis included the rate of intrauterine growth restriction, birth weight and length, neonatal head circumference. RESULTS Significant differences in the subgroups were found in the parameters intrauterine growth restriction, birth weight, length and head circumference. Women with epilepsy were affected less often than women with depression and substance abuse. Major differences were found in the group of women with substance abuse. Negative associations were found within the non-pharmacologically managed disease group itself compared to women exposed to medication. CONCLUSION The present results demonstrated a negative association between maternal neurological or psychiatric disease and pregnancy outcome in the examined parameters. However, the non-pharmacologically treated maternal disease was identified as a risk factor itself.

Abstract
BACKGROUND The associations of individual antiepileptic drugs (AEDs) with pregnancy duration and size at birth, and potential dose relations, are not well characterized. METHODS This cohort study used nationwide Swedish register data (1996-2013). Adjusting for smoking, epilepsy and other AED indications, we used linear and quantile regression to explore associations with pregnancy duration, and birth weight, length, and head circumference (the last three operationalized as z-scores). We used logistic regression for preterm delivery, small for gestational age, and microcephaly. Lamotrigine was the reference drug. RESULTS 6,720 infants were exposed to AEDs in utero; AED exposure increased over the study period. Relative to lamotrigine-exposed infants, carbamazepine-exposed infants were born, on average, 1.3 days earlier (mean [95% confidence interval]: -1.3 [-2.3 to -0.3]); were 0.1 standard deviations (SDs) lighter (-0.1 [-0.2 to 0.0]); and had a head circumference that was 0.2 SDs smaller (-0.2 [-0.3 to -0.1]). Pregabalin-exposed infants were born, on average, 1.1 days earlier (-1.1 [-3.0 to 0.8]); were 0.1 SDs lighter (-0.1 [-0.3 to 0.0]); and had the same head circumference as lamotrigine-exposed infants. Levetiracetam-exposed infants were born, on average, 0.5 days earlier (-0.5 [-2.6 to 1.6]); were 0.1 SDs lighter (-0.1 [-0.3 to 0.0]); and had a head circumference 0.1 SDs smaller (-0.1 [-0.3 to 0.1]). Valproic acid-exposed infants had, on average, the same duration of gestation and birth weight z-score as lamotrigine-exposed infants, but had a head circumference 0.2 SDs smaller (-0.2 [-0.2 to -0.1]). Associations between carbamazepine exposure and pregnancy duration and between valproic acid exposure and pregnancy duration and birth weight z-score were more negative at the left than at the right tails of the outcome distributions. Effect-measure modification and dose-response relations were noted for some of the associations. CONCLUSIONS Relative to lamotrigine, valproic acid and carbamazepine were associated with smaller head circumference.

Abstract
BACKGROUND A pattern of major and minor congenital anomalies, facial dysmorphic features, and neurodevelopmental difficulties, including cognitive and social impairments has been reported in some children exposed to sodium valproate (VPA) during pregnancy. Recognition of the increased risks of in utero exposure to VPA for congenital malformations, and for the neurodevelopmental effects in particular, has taken many years but these are now acknowledged following the publication of the outcomes of several prospective studies and registries. As with other teratogens, exposure to VPA can have variable effects, ranging from a characteristic pattern of major malformations and significant intellectual disability to the other end of the continuum, characterised by facial dysmorphism which is often difficult to discern and a more moderate effect on neurodevelopment and general health. It has become clear that some individuals with FVSD have complex needs requiring multidisciplinary care but information regarding management is currently lacking in the medical literature. METHODS An expert group was convened by ERN-ITHACA, the European Reference Network for Congenital Malformations and Intellectual Disability comprised of professionals involved in the care of individuals with FVSD and with patient representation. Review of published and unpublished literature concerning management of FVSD was undertaken and the level of evidence from these sources graded. Management recommendations were made based on strength of evidence and consensus expert opinion, in the setting of an expert consensus meeting. These were then refined using an iterative process and wider consultation. RESULTS Whilst there was strong evidence regarding the increase in risk for major congenital malformations and neurodevelopmental difficulties there was a lack of high level evidence in other areas and in particular in terms of optimal clinical management.. The expert consensus approach facilitated the formulation of management recommendations, based on literature evidence and best practice. The outcome of the review and group discussions leads us to propose the term Fetal Valproate Spectrum Disorder (FVSD) as we feel this better encompasses the broad range of effects seen following VPA exposure in utero. CONCLUSION The expert consensus approach can be used to define the best available clinical guidance for the diagnosis and management of rare disorders such as FVSD. FVSD can have medical, developmental and neuropsychological impacts with life-long consequences and affected individuals benefit from the input of a number of different health professionals.

Abstract
Juvenile myoclonic epilepsy (JME) is both a frequent and a very characteristic epileptic syndrome with female preponderance. Treatment of JME in women of childbearing potential must consider multiple factors such as desire for pregnancy, use of contraception, seizure control and previously used antiepileptic drugs (AEDs). Approximately 85% of cases are well controlled with valproate, which remains the reference AED in JME but is nowadays considered unsafe for the expecting mother and her fetus. The prescription of valproate is now severely restricted in women of childbearing potential but may still be considered, at the lowest possible dose and when pregnancies can be reliably planned, with temporary alternatives to valproate prescribed before fertilization. Alternatives have emerged, especially lamotrigine and levetiracetam, but also topiramate, zonisamide, and recently perampanel, but none of these AEDs can be considered fully safe in the context of pregnancy. In special settings, benzodiazepines and barbiturates may be useful. In some cases, combination therapy, especially lamotrigine and levetiracetam, may be useful or even required. However, lamotrigine may have the potential to aggravate JME, with promyoclonic effects. Carbamazepine, oxcarbazepine and phenytoin must be avoided. Valproate, levetiracetam, zonisamide, topiramate if the daily dose is ≤ 200 mg and perampanel if the daily dose is ≤ 10 mg do not affect combined hormonal contraception. Lamotrigine ≥ 300 mg/day has been shown to decrease levonorgestrel levels by 20% but does not compromise combined hormonal contraception. Patients with JME taking oral contraceptive should be counselled on the fact that the estrogenic component can reduce concentrations of lamotrigine by over 50%, putting patients at risk of increased seizures. Pregnancy is a therapeutic challenge, and the risk/benefit ratio for the mother and fetus must be considered when choosing the appropriate drug. Lamotrigine (< 325 mg daily in the European Registry of Antiepileptic Drugs in Pregnancy) and levetiracetam seem to be comparatively safer in pregnancy than other AEDs, especially topiramate and valproate. Plasma concentration of lamotrigine and levetiracetam decreases significantly during pregnancy, and dosage adjustments may be necessary. With persisting generalized tonic-clonic seizures, the combination of lamotrigine and levetiracetam offer the chance of seizure control and lesser risks of major congenital malformations. The risk of malformation increases when valproate or topiramate are included in the drug combination. In one study, the relative risk of autism and autism spectrum disorders (ASD) in children born to women with epilepsy (WWE) treated with valproate were, respectively, 5.2 for autism and 2.9 for ASD versus 2.12 for autism and 1.6 for ASD in WWE not treated with valproate. More studies are needed to assess the risk of autism with AEDs other than valproate. The current knowledge is that the risk appears to be double that in the general population. In patients with JME, valproate remains an essential and life-changing agent. The consequences of a lifetime of poorly controlled epilepsy need to be balanced against the teratogenic risks of valproate during limited times in a woman's life. The management of JME in WWE should include lifestyle interventions, with avoidance of sleep deprivation, and planned pregnancy.

Abstract
Background and purpose Studies in women with epilepsy (WWE) regarding pregnancy and labour complications have disclosed contradictory results. Our purpose was to investigate whether WWE have a higher risk of acute caesarean section (CS) or pregnancy complications than women without epilepsy or women with other chronic diseases and, if we found a higher risk, to explore potential explanations. Methods The study used prospectively registered obstetric data from the Oppland Perinatal Database in the period 2001–2011, containing information on 18 244 births, including 110 singleton pregnancies in mothers with validated epilepsy. Data regarding epilepsy were collected retrospectively from medical records. Results Epilepsy was a significant risk factor for acute CS, breech presentation and low birth weight in offspring [odds ratio (OR), 1.93, 95% confidence interval (CI), 1.2–3.1; OR, 2.29, 95% CI, 1.2–4.6 and OR, 2.10, 95% CI, 1.0–4.2, respectively]. In multivariate logistic regression analysis, antiepileptic drug exposure was an independent risk factor for acute CS (OR, 2.00; 95% CI, 1.06–3.77) and polytherapy was a significant risk factor for breech presentation (OR, 5.37; 95% CI, 1.13–25.57). Seizure frequency during pregnancy had no influence on the complication rate. Conclusions We found that WWE using antiepileptic drugs during pregnancy had increased rates of acute CS, breech presentation and low birth weight, and that seizure frequency during pregnancy did not influence the complication rate.

Abstract
The literature suggests that cesarean delivery or birth is carried out more often in pregnant women with epilepsy (WWE) than in pregnant women in the general population. Data were utilized from the Australian Pregnancy Register (APR) for Women on Antiepileptic Medication to investigate this issue in Australia. Over almost two decades, the mean CS rate in 1900 APR women was 39.2%, but was only 29.9% in women in the general population (relative risk (R.R.) = 1.31, 95% confidence interval (C.I.) 1.24, 1.39). Rates for forceps and suction-assisted delivery were similar in the two datasets. The 9.3% excess CS rate was almost entirely accounted for by operations carried out prior to the onset of labor. The rates for CS during labor were very similar. Only 11.0% of the WWE knew the indication for their prelabor CS, whereas 69.8% knew why theirs had been carried out during labor (odds ratio (O.R.) = 0.054; 99% C.I. 0.032, 0.089). Slightly older mothers and increased proportions of primipara probably made small contributions to the increased prelabor CS rate in the Australian WWE, but most of the excess could not be accounted for in the Register data. Australian obstetricians may have tended to regard prelabor CS as a preferable course of action in managing delivery in WWE, even in the absence of other indications.

Abstract
The role of ethnicity on pregnancy outcomes of women with epilepsy (WWE) has received little research attention but is important to guide management. The aim of this review is to identify and describe current knowledge of ethnicity for WWE giving birth. Literature searches were performed with the following terms: ethnic/race combined with epilepsy/seizure, antiepileptic drugs (AED), and/or pregnancy, and combined them with congenital malformation, birth outcome, or pregnancy complication, with English language restriction in PubMed, EMBASE, and Web of Science. Both primary studies and review articles were included. Ethnicity disparities exist in specific congenital malformations, pregnancy complications, and birth outcomes among the general population. There is also ethnicity-related diversity of AED disposition. Information on ethnicity is rarely considered in studies about pregnant WWE. The association between ethnicity and pregnancy outcomes of WWE remains to be elucidated. The lack of data relating to ethnicity in pregnancy studies among WWE needs addressing. Knowledge of potential effects of ethnicity on pregnancy outcomes in WWE will help inform better clinical care around the world.

Abstract
BACKGROUND Pre-existing conditions are imperfectly recorded in health care databases. We assessed whether pre-existing neurologic conditions (epilepsy, multiple sclerosis [MS]) were differentially recorded in the presence of major obstetric outcomes (Caesarean delivery, preterm delivery, preeclampsia) in delivery records. We also evaluated the impact of differential recording on measures of frequency and association between the conditions and outcomes. METHODS The 2011-2014 Truven Health MarketScan® Commercial Claims Dataset was used to identify pregnancies. We calculated the relative recording of epilepsy and MS at delivery hospitalization compared with a 270-day pre-delivery window both overall and by the presence of major obstetric outcomes. We estimated risk ratios for the association between epilepsy and MS with the outcomes for each ascertainment window. RESULTS We identified 909 065 pregnancies in women continuously enrolled from 270-days before the delivery date. Of women with epilepsy identified in the pre-delivery window, 73% had the condition coded at delivery. For MS, the proportion was 60%. MS recording at delivery did not vary by obstetric outcomes, however, delivery-coded epilepsy was less likely confirmed in the pre-delivery window in the presence of preeclampsia. Generally, the period of ascertainment did not meaningfully impact risk ratios, however, the risk ratio for preeclampsia associated with epilepsy was 1.67 (95% CI 1.47, 1.90) when epilepsy was ascertained at delivery and 1.26 (95% CI 1.07, 1.48) when epilepsy was ascertained in the pre-delivery window (heterogeneity, P = .007). CONCLUSIONS Ascertainment of epilepsy and MS in delivery hospitalization records underestimated prevalence. However, the window of recording generally did not impact risk ratio estimates of associations with obstetric outcomes.

Abstract
OBJECTIVE The objective of this study was to compare adverse pregnancy outcomes between pregnancies that involve epilepsy and those that do not and are identified as normal for the purposes of this paper. METHODS A retrospective cohort study was carried out by accessing the maternal-fetal medicine (MFM) database to identify and review records of singleton pregnancies with epilepsy but with no other underlying disease (study group). A parallel group of low-risk pregnancies was randomly allocated as the control group. The adverse outcomes between the two groups were compared. The primary outcomes included rates of spontaneous abortion, small for gestational age (SGA), preterm birth (PTB), low birth weight (LBW), and preeclampsia. RESULTS From a total of 44,708 deliveries, 148 pregnancies involving mothers with epilepsy and a control group of 1480 normal pregnancies were compared. The rates of spontaneous abortion, PTB, LBW, and cesarean section were slightly but significantly higher in the study group with a relative risk of 6.6 (95% confidence interval (CI): 1.9-23.3), 1.6 (95% CI: 1.1-2.2), 1.6 (95% CI: 1.1-2.3), and 1.5 (95% CI: 1.1-2.1), respectively, whereas other adverse outcomes were comparable. In the subgroup analysis, adverse outcomes tended to be higher in women with active epilepsy. However, only the rates of SGA in the group in which the disorder is active and PTB in the presence of seizures within 6months of conception were significantly increased. CONCLUSIONS Pregnancies with epilepsy, even in cases with multidisciplinary care and no other risk factors, are still significantly associated with higher adverse outcomes.

Abstract
OBJECTIVES To estimate the risk of hypertensive pregnancy complications in women with epilepsy, with and without antiepileptic drugs, and assess the risk associated with the four most common antiepileptic drugs. DESIGN A population-based cohort study using linked data from the Medical Birth Registry of Norway and the Norwegian Prescription Database. Women with epilepsy with and without antiepileptic drugs were compared with women without epilepsy. SETTING Norway, 2004-2012. PARTICIPANTS All first pregnancies of women with epilepsy and women without epilepsy were included. PRIMARY AND SECONDARY OUTCOME MEASURES Main outcome measures were hypertensive pregnancy complications: a compound variable of any hypertensive disorder, gestational hypertension, mild pre-eclampsia, severe pre-eclampsia, early onset pre-eclampsia, eclampsia and HELLP syndrome (haemolysis, elevated liver enzymes, low platelets). RESULTS In total, 1778 pregnancies in women with epilepsy and 221 662 in women without epilepsy were analysed. 682 of the women with epilepsy used antiepileptic drugs, the most common in monotherapy being: lamotrigine (n=280), carbamazepine (n=94), levetiracetam (n=71) and valproate (n=51). There was an increased risk of any hypertensive disorder in women with epilepsy (adjusted OR (aOR) 1.2, 95% CI 1.0 to 1.5) and in the subcategory using valproat (aOR 2.9, 95% CI 1.3 to 6.4). The most frequent hypertensive complication was mild pre-eclampsia and the risk was increased in women with epilepsy (aOR 1.4, 95% CI 1.1 to 1.8) and women with epilepsy with valproat (aOR 3.3, 95% CI 1.2 to 9.4). CONCLUSIONS Women with epilepsy have an increased risk of mild pre-eclampsia, but not for the severe types of hypertensive pregnancy complications. Lamotrigine and levetiracetam do not predispose for mild pre-eclampsia, whereas valproate was associated with an increased risk of mild pre-eclampsia.

Abstract
Antiepileptic medications, and valproate principally, are commonly prescribed teratogens. There is significant concern that we are not doing enough to educate clinicians and potential parents about the risks of valproate in pregnancy. There is clear advice from the Medicines and Healthcare products Regulatory Agency and the International League Against Epilepsy about the risks of valproate exposure in utero Reviews and guidelines that are focused on fetal risk, however, fall short in being able to fully replicate the complexity of a real clinical decision. Valproate is certainly life-changing if your child is one of the 10% with a major malformation or 30-40% with a neurodevelopmental disorder, but valproate is also potentially life-saving in the context of ensuring the best possible seizure control for some mothers with epilepsy. There are significant knowledge gaps regarding the risks to mothers who elect to take another drug, or to mother and baby if she comes off medication entirely. We also should be doing more to reduce rates of sudden unexpected death in epilepsy (SUDEP), which is recognised as a key target when evaluating all maternal deaths.

Abstract
There are several issues, which have to be acknowledged, when treating women with epilepsy (WWE). The need for counseling WWE in Germany with epilepsy on pregnancy-related matters was stressed in several papers and medical guidelines. Physicians treating WWE in Germany therefore should be aware of the information needs of their patients. We aimed to determine the level of pregnancy-related knowledge of WWE and their informational needs concerning pregnancy and childbirth issues in German-speaking countries by an internet-based survey. The questionnaire consisted of 18 questions addressing the characteristics of the epilepsy syndromes, the patients' experience with pregnancy, and the sources of their pregnancy-related knowledge. Another 20 items addressed the level of pregnancy-related knowledge. One hundred ninety-two women (179 patients, 13 relatives; age: 30.5±10.8years) participated. Most of the women got information and advice on the treatment of epilepsy from a neurologist (81%). Most of the women had obtained information concerning driving license (72%) followed by information about pregnancy and delivery (60%). The women, who remembered being counseled about pregnancy-related matters gave more correct answers to the pregnancy-related questions than the others (51±17% vs. 38±24%, p<0.011). Thirty-eight percent of WWE taking enzyme inducing antiepileptic drugs (AEDs) were unaware of the interaction with oral contraception. Forty-one percent of WWE taking valproate were unaware of its high teratogenicity, and 89% of WWE had not been counseled about potentially reduced bone mineral density. Forty-six percent of participants did not believe that the majority of WWE have healthy children. The findings of this survey reveal considerable information needs of WWE concerning pregnancy-related matters in German-speaking countries.

Abstract
AIMS The present study evaluates the effect of antenatal lamotrigine exposure, on short- and long-term paediatric outcome. METHODS The study included the children of 83 epileptic women treated with lamotrigine during pregnancy, at a tertiary medical centre between 2004-2014. All newborns were monitored for vital signs, congenital malformations and Finnegan score. In addition, the parents completed a questionnaire regarding their child's development and health up to the age of 12 years. RESULTS No major malformations were found in the newborns. None of the newborns had significant withdrawal symptoms by Finnegan score. The children were followed-up to the age of 12 years (56.6% were 6-12 years at the time of evaluation). There were no significant findings in the incidence of neurodevelopmental disorders. CONCLUSIONS According to our experience, lamotrigine is generally safe for pregnancy use, associated with minimal short-term complications with no long-term effects on the outcome.

Abstract
INTRODUCTION The purpose of the present study was to assess the prevalence and determinants of menstrual cycle disorders among women with epilepsy. MATERIALS AND METHODS The study included consecutive women with epilepsy who visited a university epilepsy clinic. A number of variables, including demographics, characteristics of epilepsy and its treatment, and data related to reproductive health (regularity of menstrual cycle, number of pregnancies and childbirths), were collected from medical records, seizure diaries, and a dedicated questionnaire. RESULTS The study involved 271 women with epilepsy. Focal epilepsy was diagnosed in 182 (67.2%) patients; 108 (39.8%) women had rare seizures (<1 per year), and 164 patients (60.5%) were on monotherapy. Menstrual abnormalities were found in 78 patients (28.8%). Independent variables associated with irregular cycle included younger age at onset of epilepsy (OR=0.95 per 1-year increase; P=0.008), current use of clonazepam (OR=5.36; P=0.010), and chronic use of medication(s) other than antiepileptic drug(s) (AEDs; OR=2.48; P=0.003). Childbirth rate was low in our cohort (0.50 per patient); independent predictors of being childless in studied patients included younger age, presence of menstrual disorders, and greater number of currently used AEDs. CONCLUSION Menstrual disturbances were present in 28.8% of studied women with epilepsy. Increased prevalence of menstrual abnormalities was associated with epilepsy itself (younger age at onset of epilepsy) and its treatment (ongoing use of clonazepam), as well as with chronic use of medications other than AEDs.

Abstract
Importance To date, few attempts have been made to examine associations between exposure to maternal epilepsy with or without antiepileptic drug (AED) therapy and pregnancy and perinatal outcomes. Objectives To investigate associations between epilepsy in pregnancy and risks of pregnancy and perinatal outcomes as well as whether use of AEDs influenced risks. Design, Setting, and Participants A population-based cohort study was conducted on all singleton births at 22 or more completed gestational weeks in Sweden from 1997 through 2011; of these, 1 424 279 were included in the sample. Information on AED exposure was available in the subset of offspring from July 1, 2005, to December 31, 2011. Data analysis was performed from October 1, 2016, to February 15, 2017. Main Outcomes and Measures Pregnancy, delivery, and perinatal outcomes. Multivariable Poisson log-linear regression was used to estimate adjusted risk ratios (aRRs) and 95% CIs, after adjusting for maternal age, country of origin, educational level, cohabitation with a partner, height, early pregnancy body mass index, smoking, year of delivery, maternal pregestational diabetes, hypertension, and psychiatric disorders. Results Of the 1 429 652 births included in the sample, 5373 births were in 3586 women with epilepsy; mean (SD) age at first delivery of the epilepsy cohort was 30.54 (5.18) years. Compared with pregnancies of women without epilepsy, women with epilepsy were at increased risks of adverse pregnancy and delivery outcomes, including preeclampsia (aRR 1.24; 95% CI, 1.07-1.43), infection (aRR, 1.85; 95% CI, 1.43-2.29), placental abruption (aRR, 1.68; 95% CI, 1.18-2.38), induction (aRR, 1.31; 95% CI, 1.21-1.40), elective cesarean section (aRR, 1.58; 95% CI, 1.45-1.71), and emergency cesarean section (aRR, 1.09; 95% CI, 1.00-1.20). Infants of mothers with epilepsy were at increased risks of stillbirth (aRR, 1.55; 95% CI, 1.05-2.30), having both medically indicated (aRR, 1.24; 95% CI, 1.08-1.43) and spontaneous (aRR, 1.34; 95% CI, 1.20-1.53) preterm birth, being small for gestational age at birth (aRR, 1.25; 95% CI, 1.13-1.30), and having neonatal infections (aRR, 1.42; 95% CI, 1.17-1.73), any congenital malformation (aRR, 1.48; 95% CI, 1.35-1.62), major malformations (aRR, 1.61; 95% CI, 1.43-1.81), asphyxia-related complications (aRR, 1.75; 95% CI, 1.26-2.42), Apgar score of 4 to 6 at 5 minutes (aRR, 1.34; 95% CI, 1.03-1.76), Apgar score of 0 to 3 at 5 minutes (aRR, 2.42; 95% CI, 1.62-3.61), neonatal hypoglycemia (aRR, 1.53; 95% CI, 1.34-1.75), and respiratory distress syndrome (aRR, 1.48; 95% CI, 1.30-1.68) compared with infants of unaffected women. In women with epilepsy, using AEDs during pregnancy did not increase the risks of pregnancy and perinatal complications, except for a higher rate of induction of labor (aRR, 1.30; 95% CI, 1.10-1.55). Conclusions and Relevance Epilepsy during pregnancy is associated with increased risks of adverse pregnancy and perinatal outcomes. However, AED use during pregnancy is generally not associated with adverse outcomes.

Abstract
PURPOSE Epilepsy is one of the most common neurological diseases during pregnancy. However, the influence of epilepsy on fetal growth is not understood. Thus, this study conducted a meta-analysis to determine the influence of epilepsy during pregnancy on fetal growth restriction (FGR). METHODS BIOSIS, Medline, Embase, and PubMed databases were searched between January 2000 and January 2016. Without imposing language or regional restrictions, referenced articles were selected. RESULTS Final analysis included 684 citations from 11 studies. Estimated risk of FGR was 1.28-fold higher in epileptic pregnant women than in non-epileptic women [95% confidence interval (95% CI) 1.09-1.50, p < 0.05]. Given the course of previous studies, hierarchical analysis of pregnant women who use antiepileptic drugs (AEDs) was conducted. Results show that FGR rate is significantly increased even if AEDs were taken [odds ratio 1.26, 95% CI 1.13-1.41, p < 0.05]. CONCLUSIONS Although modest bias cannot be avoided, our meta-analysis indicated that epilepsy participates in fetal development as an unfavorable factor, and AEDs seemed to be useless in decreasing the occurrence rate of FGR.

Abstract
This study detected the impact of maternal carbamazepine (CBZ) on the fetal neuroendocrine-cytokines axis. 25 or 50mg/kg of CBZ was intraperitoneally administrated to pregnant albino rats from the gestation day (GD) 1 to 20. Both administrations of CBZ caused a hypothyroidism in dams and fetuses whereas the decreases in serum thyroxine (T4) and triiodothyronine (T3) and increases in serum thyrotropin (TSH) levels were highly significant (LSD; P <0.01) at GD 20 compared to untreated control dams. Also, both administrations had undesirable impacts on the maternofetal body weight, litter weight, survival of dams and fetuses, and their food consumption in comparison to the corresponding control. These administrations also elicited a reduction in fetal serum growth hormone (GH), interferon-γ (IFNγ), interleukins (IL-2 & 4) and prostaglandin E2 (PGE2) levels. Also, the elevation in fetal serum tumor necrosis factor-alpha (TNFα), transforming growth factor-beta (TGFβ), and interleukins (IL-1β & 17) levels was observed at embryonic day (ED) 20. Moreover, there were a cellular fragmentation, distortion, hyperemia, oedema and vacuolation in the fetal cerebellar cortex due to both maternal administrations. These developmental changes were dose-dependent. These novel results suggest that CBZ may act as a developmental immunoneuroendocrine disruptor.

Abstract
IMPORTANCE Between 0.3% and 0.5% of all pregnancies occur among women with epilepsy. Evidence suggests an increase in perinatal morbidity and mortality among women with epilepsy. However, these risks have not been quantified in large population-based samples. OBJECTIVE To report on the risk for death and adverse outcomes at the time of delivery for women with epilepsy in the United States. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study of pregnant women identified through delivery hospitalization records from the 2007-2011 Nationwide Inpatient Sample. From this representative sample of 20% of all US hospitals, we obtained a weighted sample of delivery hospitalizations from 69 385 women with epilepsy and 20 449 532 women without epilepsy. MAIN OUTCOMES AND MEASURES Obstetrical outcomes including maternal death, cesarean delivery, length of stay, preeclampsia, preterm labor, and stillbirth. RESULTS Women with epilepsy had a risk of death during delivery hospitalization of 80 deaths per 100 000 pregnancies, significantly higher than the 6 deaths per 100 000 pregnancies found among women without epilepsy (adjusted odds ratio [OR], 11.46 [95% CI, 8.64-15.19]). Women with epilepsy were also at a heightened risk for other adverse outcomes, including preeclampsia (adjusted OR, 1.59 [95% CI, 1.54-1.63]), preterm labor (adjusted OR, 1.54 [95% CI, 1.50-1.57]), and stillbirth (adjusted OR, 1.27 [95% CI, 1.17-1.38]), and had increased health care utilization, including an increased risk of cesarean delivery (adjusted OR, 1.40 [95% CI, 1.38-1.42]) and prolonged length of hospital stay (>6 days) among both women with cesarean deliveries (adjusted OR, 2.13 [95% CI, 2.03-2.23]) and women with vaginal deliveries (adjusted OR, 2.60 [95% CI, 2.41-2.80]). CONCLUSIONS AND RELEVANCE Findings suggest that women with epilepsy are at considerably heightened risk for many adverse outcomes during their delivery hospitalization, including a more than 10-fold increased risk of death, and that increased clinical attention is imperative for these pregnancies.

Abstract
BACKGROUND Antenatal care of women with epilepsy is varied. The association of epilepsy and antiepileptic drug exposure with pregnancy outcomes needs to be quantified to guide management. We did a systematic review and meta-analysis to investigate the association between epilepsy and reproductive outcomes, with or without exposure to antiepileptic drugs. METHODS We searched MEDLINE, Embase, Cochrane, AMED, and CINAHL between Jan 1, 1990, and Jan 21, 2015, with no language or regional restrictions, for observational studies of pregnant women with epilepsy, which assessed the risk of obstetric complications in the antenatal, intrapartum, or postnatal period, and any neonatal complications. We used the Newcastle-Ottawa Scale to assess the methodological quality of the included studies, risk of bias in the selection and comparability of cohorts, and outcome. We assessed the odds of maternal and fetal complications (excluding congenital malformations) by comparing pregnant women with and without epilepsy and undertook subgroup analysis based on antiepileptic drug exposure in women with epilepsy. We summarised the association as odds ratio (OR; 95% CI) using random effects meta-analysis. The PROSPERO ID of this Systematic Review's protocol is CRD42014007547. FINDINGS Of 7050 citations identified, 38 studies from low-income and high-income countries met our inclusion criteria (39 articles including 2,837,325 pregnancies). Women with epilepsy versus those without (2,809,984 pregnancies) had increased odds of spontaneous miscarriage (OR 1·54, 95% CI 1·02-2·32; I(2)=67%), antepartum haemorrhage (1·49, 1·01-2·20; I(2)=37%), post-partum haemorrhage (1·29, 1·13-1·49; I(2)=41%), hypertensive disorders (1·37, 1·21-1·55; I(2)=23%), induction of labour (1·67, 1·31-2·11; I(2)=64%), caesarean section (1·40, 1·23-1·58; I(2)=66%), any preterm birth (<37 weeks of gestation; 1·16, 1·01-1·34; I(2)=64%), and fetal growth restriction (1·26, 1·20-1·33; I(2)=1%). The odds of early preterm birth, gestational diabetes, fetal death or stillbirth, perinatal death, or admission to neonatal intensive care unit did not differ between women with epilepsy and those without the disorder. INTERPRETATION A small but significant association of epilepsy, exposure to antiepileptic drugs, and adverse outcomes exists in pregnancy. This increased risk should be taken into account when counselling women with epilepsy. FUNDING EBM CONNECT Collaboration.

Abstract
INTRODUCTION Drugs teratogenicity has been studied for many years, especially teratogenic effects of antiepileptic drugs, because of the important impact that epilepsy has always had for young women, but data from literature are often conflicting. AREAS COVERED We have carried out a critical review of all human studies about the antiepileptic drugs teratogenicity. A systematic search was performed in Medline and PubMed up to May 1, 2015. The use of older antiepileptic drugs in pregnancy is associated with an increased risk of fetus malformations; in particular, Valproate can determine neural-tube-like defects; in Phenytoin and Phenobarbital-exposed pregnancies, orofacial clefts, cardiac and genitourinary malformations are the major anomalies described. Spina bifida is the only specific major congenital malformation significantly associated with exposure to Carbamazepine monotherapy Despite the small number of studies on the teratogenic effects of new antiepileptic drugs, the analysis of the literature shows that exposure of the fetus to the new antiepileptic drugs is associated with a lower risk of major congenital malformations compared to the use of older drugs. EXPERT OPINION Where possible, Valproate should be avoided in women of childbearing potential. Results about the safety of newer antiepileptic drugs require validation and further investigation.
