Perceptions of reproductive risk among women with epilepsy of childbearing age.

BACKGROUND: Having children or planning to have children may raise many questions for women with epilepsy. Seizures and antiseizure medications (ASMs) impact contraception, fetal/early childhood development, and maternal health. Little is known regarding patients' perspectives about reproductive risk and how those perspectives influence reproductive decision-making. METHODS: As a quality improvement initiative, we distributed an electronic survey within our health system to women ages 21-45 with a primary diagnosis of epilepsy/seizures. We then performed an exploratory research study to investigate perceptions of risk of epilepsy and ASMs on reproductive health and decision making. Additionally, we looked at clinical characteristics as possible predictors of fear impacting reproductive decisions. RESULTS: There were 267 responses (32% responder rate); after exclusion criteria, 233 respondents were included in the study. There were mixed responses about how fear of ASM teratogenicity impacted decisions about having children (33% very much, 34% a little, 33% not at all). While 45% responded that fear of having a child with epilepsy/seizures did not at all affect decisions about having children, for 24% this very much affected their decision. In total 42% of respondents reported they had had children. When we evaluated the impact of certain clinical characteristics, we found ASM number and valproic acid use impacted reproductive decision making, while other expected characteristics (e.g., drug-refractoriness and convulsive seizures) did not. DISCUSSION: We found variation in perceptions of risk. Overall, our data support the very personalized nature of preferences and the need for individualized counseling when guiding patients in reproductive decision making.

A Review of Concordance and Quality in Clinical Guidelines for Hormonal Contraceptives to Mitigate Drug-Drug Interactions in Women With Epilepsy.

PURPOSE: Concomitant use of hormonal contraceptive agents (HCAs) and enzyme-inducting antiepileptic drugs (EIAEDs) may lead to contraceptive failure and unintended pregnancy. This review identified and evaluated concordance and quality of clinical treatment guidelines related to the use of HCAs in women with epilepsy (WWE) receiving EIAEDs. METHODS: Relevant clinical guidelines were identified across four databases and were independently evaluated for quality utilizing the AGREE-II protocol instrument. Quality in this context is defined as the rigor and transparency of the methodologies used to develop the guideline. Guidelines were further assessed in terms of concordance and discordance with the latest body of knowledge concerning the use of hormonal contraception in the presence of EIAEDs. RESULTS: A total of n = 5 guidelines were retrieved and evaluated. Overall guideline scores ranged from 17% to 92%, while individual domain scores ranged from 0% to 100%. Contraceptive guidelines consistently recommended the use of intrauterine systems and long-acting injectables in the presence of EIAEDs, recommended against the use of oral, transdermal, and vaginal ring contraceptives, and differed regarding recommendations related to implants. Guidelines agreed regarding recommendations that women treated with EIAEDs should receive intrauterine systems and long-acting injectables; however, the suggested frequency of administration of injectable contraceptives differed. The use of intrauterine systems in this population is supported by evidence, but there is uncertainty surrounding the use of long-acting injectables and contraceptive implants. CONCLUSIONS: To mitigate the risk of unintended pregnancy and its consequences, recommendations related to implants and long-acting injectable contraceptives should be evidence-based.

Psychosocial burden in mothers with epilepsy and their caregiver: Feasibility and preliminary results of a digital screening procedure.

OBJECTIVE: The present study aims to evaluate the feasibility of utilizing a digital procedure to screen for anxiety and depression as well as impairments in psychosocial aspects, such as social support, social activity and quality of life (QoL) in women with epilepsy (WWE) after childbirth. Furthermore, the study intends to digitally screen for burden of the respective caregivers in WWE compared to a healthy control group. MATERIALS AND METHODS: This comparative cross-sectional study was conducted in the post-partum period on 30 WWE and 33 healthy controls who gave birth between 01/2018 and 05/2021. Additionally, 24 caregivers of WWE and 26 caregivers of healthy mothers took part in this study. Information on psychosocial health and psychosocial burden was collected digitally using the short version of the Social Support Questionnaire, the Social Activity Self-Report Scale and the Hospital Anxiety and Depression Scale. The caregiver burden was digitally assessed with the Zarit Burden Scale in its German adaptation (i.e., Zarit Burden Interview and the Family Burden Questionnaire). Furthermore, QoL was assessed with the QOLIE-31 (Quality of Life in Epilepsy Inventory) in WWE and with the Life Satisfaction Questionnaire in healthy controls. RESULTS: When comparing WWE and healthy controls, the groups were comparable on psychosocial aspects, such as self-reported social support, anxiety, depression and social activity, when assessed with self-report measures in a digital screening procedure. Although not significantly different between groups, anxiety, depression, self-reported social support and social activity were correlated with overall QoL in both, WWE and healthy controls. Caregivers of WWE and healthy controls were neither significantly different in their objective burden nor in their subjective burden as reported in digitally applied self-report measures. CONCLUSION: Although not significantly different between groups, given the correlation between psychosocial aspects and QoL, it is worthwhile to include these aspects in standard clinical screening extending beyond the screening of anxiety and depression in WWE. Overall, the preliminary psychosocial data presented in this study suggest that a digital assessment of psychosocial burden seems reasonable in WWE and warrants integration into further research and clinical practice. Nevertheless, since no significant differences concerning psychosocial aspects were found in the present study, one may argue that highly specialized clinical care, as provided in the present study, may counteract potential psychosocial impairment experienced by WWE who do not receive such specialized care. Hence, further investigations outside of specialized outpatient clinics as well as prospective investigations of subjective factors that may dynamically change during pregnancy ought to be addressed in clinical practice and research for improving care during and after pregnancy in WWE.

Global burden and management of women with epilepsy in pregnancy: A modeling study.

BACKGROUND: Most pregnant women with epilepsy do not receive proper medical care, which creates a special burden worldwide. We aimed to qualify this special global burden and assess the impact of different clinical management strategies to reduce it. METHODS: The data used in this study were extracted from articles published between 2005 and 2022. We calculated the economic costs associated with major burdens experienced by pregnant women with epilepsy. We developed a microsimulation model to estimate the different effects of various interventions and their combinations as integrated strategies for pregnant women with epilepsy and related burden reduction. We also compared the regional differences in disease burden and interventions. FINDINGS: The total economic burden for pregnant women with epilepsy is estimated to reach $1.8 billion globally annually, which is more than three times the burden for epilepsy alone. Folic acid supplementation is projected to be the most effective intervention, with a 9.1% reduction in major congenital malformations, a 14.9% reduction in autism spectrum disorder, and a 10.8% reduction in offspring-related economic burden globally annually. Integrated strategies are associated with a reduced economic burden of up to $37.7 million annually globally. Folic acid supplementation is the most effective intervention in high- and upper-middle-income countries, whereas changes in antiseizure medication prescriptions are more effective in lower-middle- and low-income countries. CONCLUSION: This study highlights the huge burden for pregnant women with epilepsy and actions that must be taken to improve their quality of life. FUNDING: This work was supported by the Sichuan Science and Technology Program (2023YFS0047).

Monitoring levetiracetam concentration in saliva during pregnancy is stable and feasible.

AIMS: This multicenter prospective cohort study (registration no. ChiCTR2000032089) aimed to investigate the relationship between saliva and plasma levetiracetam concentrations to determine whether saliva could be used for routine monitoring of levetiracetam during pregnancy. METHODS: The slot concentrations of levetiracetam in simultaneously obtained saliva and plasma samples were measured using UPLC-MS/MS. The correlations between saliva and plasma levetiracetam concentrations and the dose-normalized concentrations were compared among pregnant women in different stages and nonpregnant control participants with epilepsy. RESULTS: In total, 231 patients with 407 plasma and saliva sample pairs were enrolled from 39 centers. Linear relationships between salivary and plasma levetiracetam concentrations were reported in the enrolled population (r = 0.898, p < 0.001), including pregnant (r = 0.935, p < 0.001) and nonpregnant participants (r = 0.882, p < 0.001). Plasma concentrations were moderately higher than saliva concentrations, with ratios of saliva to plasma concentrations of 0.98 for nonpregnant women, 0.98, 1, and 1.12 for pregnant women during the first trimester, the second trimester, the and third trimester, respectively. The effective range of saliva levetiracetam concentration was found to be 9.98 µg/mL (lower limit) with an area under the curve (AUC) of 0.937 (95% confidence intervals, 0.915-0.959), sensitivity of 88.9%, specificity of 86.8%, and p < 0.001, to 24.05 µg/mL (upper limit) with an AUC of 0.952 (0.914-0.99), sensitivity of 100%, specificity of 92.3%, and p = 0.007. CONCLUSION: The saliva/plasma concentration ratio of levetiracetam remains constant during pregnancy and is similar to that in non-pregnant individuals. Monitoring levetiracetam concentration in saliva during pregnancy should be widely promoted.

Physical fitness in Indian women with epilepsy on anti-seizure medications and its association with reproductive status, quality of life and stigma: A cross-sectional study.

PURPOSE: To determine the status of physical fitness, reproductive abnormalities, QOL and epilepsy associated stigma in women with epilepsy (WWE) and their association with ASM therapy and seizure frequency. METHODS: This cross-sectional study included WWE of reproductive age (18-50 years) on antiseizure medications (ASMs) for at least three months before enrolment. Physical fitness was assessed using International Physical Activity Questionnaires (IPAQ) and Body composition analysis. Subjects were interviewed for menstrual abnormalities [menstrual disturbance or Polycystic Ovary Syndrome (PCOS)/hirsutism]. Validated questionnaires were used for assessment of, QOL (QOLIE-10) and Stigma in epilepsy (Epilepsy Stigma Scale). Sub-group analysis was done to compare the above parameters on the basis of a) type of therapy (mono or polytherapy), b) type of ASMs treatment (conventional, newer, or conventional + newer ASMs), and c) seizure type and (d) seizure frequency. Correlation and regression analysis were done to find out the association among different variables with physical fitness. RESULTS: The overall prevalence of poor physical fitness, reproductive abnormalities, worsened QOL and stigma in the enrolled WWE (n = 203) were 21.18 %, 20.19 %, 52.7 %, and 21.67 %, respectively. Sub-group analysis revealed that WWE on monotherapy (n = 99) had higher median IPAQ score (p = 0.002), comparatively less reproductive abnormalities (24.03 %, p = 0.008), and higher stigma (24.03 %, p = 0.04) than polytherapy group. WWE on conventional ASMs had significantly higher IPAQ scores compared to newer and conventional + newer ASMs groups (p = 0.02). The prevalence of poor physical fitness and stigma was significantly higher in WWE with higher number of seizures (p = 0.007, <0.001, respectively). No significant difference in QOL was observed on the basis of ASM type and therapy; however, WWE with generalized onset seizures had worsened QOL compared to those with focal onset seizures (p = 0.04). A significant negative correlation was found among seizure frequency and IPAQ score in WWE (p = 0.04). CONCLUSION: WWE on polytherapy were physically less active, higher occurrence of reproductive abnormalities, and stigma compared to the monotherapy group. WWE with higher seizure frequency had poor physical fitness, and higher stigma compared to those with lesser number of seizures. These findings may aid value in optimization of ASM treatment in WWE of reproductive age.

Hormonal Changes in Women with Epilepsy.

Epilepsy is a prevalent neurological disorder among women globally, often requiring long-term treatment. Hormonal fluctuations in women with epilepsy (WWE) can have reciprocal effects on epilepsy and antiseizure medications (ASMs), posing significant challenges for WWE. Notably, WWE commonly experience endocrine alterations such as thyroid dysfunctions, low bone metabolism, and reproductive hormone irregularities. On the one hand, the presence of hormones in women with epilepsy affects their susceptibility to epilepsy as well as the metabolism of antiseizure medications in various ways. On the other hand, epilepsy itself and the use of antiseizure medications impact the production, secretion, and metabolism of hormones, resulting in low fertility, increased risk of pregnancy complications, negative offspring outcomes, and so on. In order to develop more precise treatment strategies in the future, it is necessary to comprehend the explicit relationships between hormones, epilepsy, and antiseizure medications, as well as to elucidate the currently known mechanisms underlying these interactions.

Challenges to epilepsy management in Rwandan women living with epilepsy.

BACKGROUND AND PURPOSE: In Rwanda, epilepsy prevalence ranges between 29‰ and 49‰. Many women living with epilepsy (WwE) are of childbearing age. Epilepsy characteristics and management, contraception, pregnancy, puerperium and stigma in WwE presenting at the neurology clinic of Ndera, Rwanda, were investigated. METHODS: This prospective cross-sectional study investigated demographics, epilepsy characteristics, treatment, contraception, folic acid use, pregnancy, puerperium and stigma in WwE aged ≥18 years. Subgroups were analysed by status of any pregnancy and time of epilepsy diagnosis relative to pregnancy, with significant differences expected. RESULTS: During December 2020 and January 2021, a hundred WwE were enrolled (range 18-67 years). Fifty-two women had never been pregnant, 39 women had epilepsy onset before pregnancy and nine were diagnosed after pregnancy. No significant differences in age, marital status or occupation were observed. Contraception was used by 27%, of whom 50% were taking enzyme-inducing anti-epileptic medication. Valproate was used by 46% of WwE of reproductive age. Thirty-nine women with epilepsy onset before pregnancy reported 91 pregnancies, with 14% spontaneous abortions. None used folic acid before conception, and 59% only during pregnancy. Five of 78 newborns were preterm. No offspring had major congenital malformations. Nearly 25% of WwE were not compliant with their anti-epileptic medication schedule during pregnancy or breastfeeding. Internalized stigma was observed in more than 60%. Up to 25% had been discriminated against at school or work. CONCLUSION: A comprehensive strategy considering the reproductive health and societal challenges of WwE is needed to drive optimal epilepsy management, reproductive health outcomes and societal inclusion.

Clinical characteristics, seizure control, and delivery outcomes in pregnant women with focal and generalized epilepsies.

OBJECTIVE: To prospectively investigate the course of epilepsy and assess seizure control during pregnancy in women with focal epilepsy (FE) compared with generalized epilepsy (GE), to ascertain the effects of epilepsy and its types on delivery and neonatal outcomes, and to compare adverse outcomes between pregnancies complicated by epilepsy and normal pregnancies. METHODS: 124 pregnant women with epilepsy (WWE) were enrolled in a prospective study. Obstetric and neonatal outcomes were compared with those of 277 healthy women in the control group. RESULTS: Occurrence of seizures during pregnancy was more often in FE (77.1 %) compared with GE (50.0 %) (Odds ratio [OR] 2.08; 95 % confidence interval [CI] 0.97-4.46, p = 0.06); the overall seizure freedom was significantly higher in women with GE compared with women with FE (p = 0.0038). Poor seizure control one year prior to the pregnancy and nonadherence to treatment were significantly associated with presence of seizures during pregnancy (p < 0.0001). Compared with pregnancies of women without epilepsy, WWE were at increased risk of cesarean section (CS) (p < 0.0001) and preterm birth (p = 0.03). Offspring of mothers with epilepsy were at higher risks of Apgar scores at 5 min ≤7 (p < 0.0001) and perinatal hypoxia (p = 0.03) compared with infants of unaffected women. Seizures during pregnancy were significantly correlated with the higher rate of CS, Apgar scores at 5 min ≤7, and perinatal hypoxia (p = 0.0069; p = 0.0098; and p = 0.0045, respectively). The risks of adverse outcomes were not significantly increased in women with FE compared to women with GE. CONCLUSION: Epileptic seizures in pregnancy are associated with increased risks of adverse delivery and neonatal outcomes. Hence, early assessment of seizure disorder, adequate seizure control prior to and during pregnancy, and effective treatment are required to prevent potential seizure-related complications and improve maternal and fetal outcomes.

Pregnancy-related knowledge in women with epilepsy in childbearing age: A pilot questionnaire survey from China.

PURPOSE: We aim to understand the knowledge of and attitudes toward pregnancy issues among women with epilepsy (WWE) and their caregivers and analyze the answers from the questionnaire to expose topics that require educational activities; thus, WWE experiences pregnancy better. METHODS: WWE at their childbearing age and/or their caregivers who entered the Fourth Affiliated Hospital of Zhejiang University for treatment of their condition were invited to fill out a questionnaire between March 1 and November 31, 2022. RESULTS: A combined total of 205 WWE and 142 caregivers completed the questionnaires. Among the surveyed WWE, a majority (63.74%) reported experiencing at least one miscarriage or induced abortion. However, a significant proportion (84.62%) of these WWE were still able to successfully give birth to at least one child. Furthermore, the offspring of these WWE showed no significant differences compared to the offspring of women without epilepsy, as reported by 93.51% of the participants. The participants' knowledge regarding the impact of epilepsy on pregnancy was found to be comparable, with average scores of 7.74 and 7.84, respectively. The participants exhibited a limited comprehension of antiseizure medications (ASMs)-related knowledge, specifically pertaining to ASMs adjustment during pregnancy (17.56% vs. 16.90%) and offspring outcomes (30.24% vs. 26.06%). Statistical analysis revealed significant correlations between the overall score and education level (p < .001), as well as epilepsy duration (p = .008). Regarding the source of knowledge, participants acknowledged primarily relying on neurologists, who remained their preferred choice for consultation. CONCLUSION: In our study, the understanding of pregnancy-related knowledge did not differ from WWE and their caregivers, both are far from satisfactory in certain areas. It is urgent for WWE and their caregivers to improve their pregnancy-related knowledge of epilepsy. As their primary access is from knowledgeable health care professionals like neurologists, well-trained neurologists in epilepsy management during pregnancy are in need.

Association of oxcarbazepine concentration with seizure frequency in pregnant women with epilepsy.

The management of epilepsy during pregnancy presents particular challenges for neurologists worldwide. Currently, there are no clear recommendations for oxcarbazepine (OXC) specific target concentration during pregnancy. We conducted this retrospective observational cohort study on pregnant women with epilepsy (WWE) who received OXC monotherapy or polytherapy, at the epilepsy outpatient clinic of a tertiary hospital in eastern China. Sixteen pregnancies of 16 WWE were split into the seizure-free group or the non-seizure-free group, according to whether they had been seizure free for more than one year prior to conception or not. There was a significantly decrease in OXC concentration throughout pregnancy, as indicated by the concentration/dose ratio and the ratio of target concentration (RTC). The second trimester of pregnancy was the period when seizure deterioration occurred the most, particularly in the non-seizure-free group. Lower RTC_OXC was identified to be a risk factor for increasing seizure frequency in both the total group and the non-seizure-free group in both univariate and multivariate analysis, with a threshold of 0.575 for differentiating patients at high-risk and low-risk for seizure deterioration. In conclusion, this study suggested an OXC concentration threshold of 0.575 during pregnancy for assisting neurologists in OXC drug monitoring and dose adaptation.

Management of status epilepticus in pregnancy: a clinician survey.

BACKGROUND: Status epilepticus in pregnancy (SEP) is rare and life-threatening for both mother and fetus. There are well-established guidelines for the management of women with epilepsy during pregnancy; however, there is little evidence guiding the management of SEP, leading to uncertainty among treating physicians. Therefore, this survey aims to investigate the real-world practices of physicians treating SEP to explore management approaches for improvements in care. METHODS: An anonymous, electronic survey was created and distributed to neurointensivists and neurologists between September and December 2021. RESULTS: One hundred physicians initiated the survey and 95 completed it in full: 87 (87%, 87/100) identified neurology as their primary specialty, 31 had subspecialty training in neurocritical care, and 48 had subspecialty training in epilepsy and/or clinical neurophysiology. Over half of the survey respondents (67%, 67/100) reported having participated in the management of SEP, with 48.9% (49/98) having done so in the past year. Most survey respondents (73%, 73/100) reported that their management approach to SEP is different than that of non-pregnant patients. Survey respondents were more likely to involve epilepsy consultants when treating SEP (58.5%, 58/99) and the vast majority involved Obstetrics/Maternal Fetal Medicine consultants (90.8%, 89/98). Survey respondents showed a clear preference for levetiracetam (89.7%, 87/97) in the treatment of benzodiazepine refractory status epilepticus followed by lacosamide (61%, 60/98) if an additional second line agent was needed. Valproate and phenobarbital were unlikely to be used. There was less agreement for the management of refractory and super-refractory SEP. CONCLUSIONS: Levetiracetam is the most frequently used anti-seizure medication (ASM) for benzodiazepine-refractory SEP. Survey participants tended to manage SEP differently than in non-pregnant patients including greater involvement of interdisciplinary teams as well as avoidance of ASMs associated with known teratogenicity.

Lamotrigine and exogenous estrogen among females with epilepsy: A retrospective analysis of administrative claims data.

OBJECTIVE: Exogenous estrogen reduces lamotrigine serum concentrations. Little is known about whether providers adjust lamotrigine doses for addition of exogenous estrogen among people with epilepsy, despite expert recommendations. We determined the incidence of dose increases in lamotrigine following incident prescription of estrogen among females with epilepsy (FWE) in claims data. METHODS: We used Optum's de-identified Clinformatics® Data Mart Database to create a cohort of U.S. FWE prescribed lamotrigine at a stable dose, with a subsequent prescription for estrogen from 2011 to 2021. We calculated cumulative incidence functions of dose increases in lamotrigine following prescription of exogenous estrogen. We performed a Cox proportional hazards model for multiple candidate predictors of a lamotrigine dose increase. RESULTS: The cohort included 643 FWE, with median age of 31 (interquartile ratio [IQR] 20-42). The cumulative incidence of any lamotrigine increase was 28% (95% confidence interval [CI] 25%-32%). The median number of days after the first estrogen fill until the first lamotrigine adjustment was 118 (IQR 48-188). In unadjusted Cox models, older age, use of estrogen in hormone replacement therapy as opposed to contraception, and annual household income of $50,000-$99,999 (compared with <$50,000) were significant negative predictors of a dose adjustment in lamotrigine with hazard ratios (HRs) of 0.82 (95% CI 0.72-0.92), 0.63 (95% CI 0.42-0.95), and 0.62 (95% CI 0.40-0.95). In the adjusted Cox model, age and income remained significant predictors with HRs of 0.79 (95% CI 0.66-0.94) and 0.59 (95% CI 0.36-0.95). CONCLUSION: Dose increase of lamotrigine following addition of exogenous estrogen is rare among U.S. FWE, with potential disparities based on age and income level. More guidance may be needed for providers on this topic.

The impact of epilepsy and antiseizure medications on pregnancy and neonatal outcomes: A nationwide cohort study.

PURPOSE: Our objective was to assess the adverse outcomes during pregnancy, as well as for the fetus and neonates, in women with epilepsy, both with and without the use of antiseizure medications (ASMs). METHODS: A cohort of singleton pregnancies between January 1, 2004 and December 31, 2014 was identified using the Taiwan National Health Database. The pregnancies were categorized into ASM exposure, ASM nonexposure, and control (consisting of women without an epilepsy diagnosis) groups. We recorded adverse outcomes in neonates and documented pregnancy complications. The generalized estimating equation with logit link was used to estimate adjusted odds ratios. RESULTS: There were 629 singleton pregnancies in the group exposed to ASMs, 771 in the epilepsy group without ASM exposure, and 2,004,479 in the control group. Women with epilepsy had a significantly higher risk of puerperal cerebrovascular diseases (adjusted odds ratios in the exposure and nonexposure groups = 54.46 and 20.37, respectively), respiratory distress syndrome (5.1 and 2.99), mortality (3.15 and 3.22), sepsis (2.67 and 2.54), pregnancy-related hypertension (1.71 and 1.8), preeclampsia (1.87 and 1.79), cesarean delivery (1.72 and 2.15), and preterm labor (1.38 and 1.56). The use of ASMs may increase the risk of eclampsia (adjusted odds ratio = 12.27). Compared to controls, fetuses/neonates born to women with epilepsy had a higher risk of unexplained stillbirth (adjusted odds ratios in the exposure and nonexposure groups = 2.51 and 2.37, respectively), congenital anomaly (1.37 and 1.33), central nervous system malformation (3.57 and 2.25), low birth weight (1.90 and 1.97), and a low Apgar score at 5 min (2.63 and 1.3). The use of ASMs may introduce an additional risk of small for gestational age; the adjusted odds ratio was 1.51. CONCLUSION: Women with epilepsy, irrespective of their exposure to ASMs, had a slightly elevated risk of pregnancy and perinatal complications. Puerperal cerebrovascular diseases may be a hidden risk for women with epilepsy.

Management of epilepsy in pregnancy: What we still need to learn.

Safe pregnancies have been a major concern for women with epilepsy. With more than 50 years of research, we have learned that antiseizure medications (ASMs) differ in their teratogenic risk. Valproate is associated with greater risks for malformations and adverse neurodevelopmental outcomes than other ASMs. Furthermore, seizure control is important for maternal health in pregnancy and it can be affected by a decline in serum concentrations of many ASMs during pregnancy. However, significant knowledge gaps remain. First, there is insufficient evidence about the relative teratogenic risks of most newer generation ASMs, as well as diverse ASM combinations. Similarly, information on gestation-induced changes in maternal serum levels and transfer into breastmilk is inadequate for the majority of the newer ASMs. Further, the optimal dose of folate supplementation remains unknown for women with epilepsy. Finally, most of previous studies on epilepsy and pregnancy come from Europe or North America. Efforts should be made to include more countries in collaboration with existing prospective epilepsy and pregnancy studies to increase the cohort size while at the same time enhancing the generalizability of the results. Large countries, such as China, present great potential to shorten the time to obtain answers to important unsolved questions.

Comparative analysis of three decades' experience in the management of pregnant women with epilepsy: a real-life scenario.

Introduction: People with epilepsy have to face many challenges, including regular follow-ups, the need to take antiseizure medications (ASMs), and the fear of seizures. Pregnant women with epilepsy (PWWE) are a special group with even more challenges because they are responsible for the fetus. We aimed to evaluate the change in the frequency of pregnancies over the years and the possible role of newer types of ASMs concerning this change, the shift in medication use over three decades, and their possible impact on the outcome of the observed pregnancies. Methods: Data were retrieved from the prospective Epilepsy Database of the Outpatient Clinic at our tertiary center between 1 January 1992 and 31 December 2020. Groups were formed for comparison in time and depending on whether regular care consultation was our task. Statistical analysis was carried out using Microsoft Office Excel 2021. Basic statistics and categorical variables were assessed using Pearson's χ2 test with Yates' correction. Differences were considered significant if the p-value was <0.05. The odds ratio and 95% confidence intervals were calculated wherever needed. Results: Altogether, 181 pregnancies were studied, mostly after 2002. The regular follow-up group consisted of 101 patients, with 44.5% presenting in the first trimester. The majority of seizures were either generalized or focal to bilateral tonic-clonic seizure types (85.6%). Pregnancies ended in live births in 91.7%, which gradually improved over time, while spontaneous abortion did not differ significantly in the time interval groups. Mostly, monotherapy was provided. PWWEs had higher chances for seizure freedom in the regular-care group I: OR = 2.9 (2.15-3.65) p < 0.0001. A shift toward newer-type ASMs was found as time passed. Levetiracetam and lamotrigine were more commonly used in the regular care group I than by those patients who were sent to consultation only and not treated at our center [OR = 3.18 (2.49-3.87)] p < 0.0001. Conclusion: This is the first study in our region to evaluate experience in the treatment and outcome of PWWE. Having received reliable care and safer ASMs, the number of pregnancies among PWWEs grew. Data suggested that specialized centers' care offered cooperation with obstetricians is important. Moreover, professional care can also enable PWWEs to have uneventful pregnancies.

Patterns and predictors of sexual dysfunction in women with epilepsy.

OBJECTIVES: Available data about sexual-related problems among Egyptian women with epilepsy (WWE) are scarce. Hence, this work aimed to study the pattern and predictors of sexual dysfunction in a sample of Egyptian WWE. METHODS: In this cross-sectional study, sexually active WWE and age and years of marriage-matched healthy controls were included. The Female Sexual Function Index questionnaire (FSFI) was used to assess sexual function in both groups. RESULTS: In the patient group (n = 142), the median age was 33 (28-39), whereas the median age of the control group (n = 142) was 33.5 (28-36). Women with epilepsy had significantly lower desire, arousal, pain, and FSFI-total scores than the control group (P = 0.001, 0.001, 0.023, 0.008, respectively). There was a significant difference between the FSFI-total score of women on polytherapy and those on monotherapy (P = 0.042), as well as between those on enzyme-inducing ASMs and those on ASMs that did not affect P450 (P = 0.032). Seizure frequency in the last three months was negatively correlated with scores of desire, arousal, lubrication, orgasm, and satisfaction (P 0.047, 0.02, 0.009, 0.013, 0.046, respectively). By multiple backward linear regression models, age, and seizure frequency were the significant predictors of the FSFI-total score (B -0.219, -0.33, respectively). CONCLUSION: The pattern of sexual dysfunction among Egyptian WWE is characterized by reduced sexual desire, arousal deficits, and sexual-related pain. Seizure frequency, epilepsy duration, enzyme-inducing medications, and multiple anti-seizure medications (ASMs) may adversely affect WWE's sexual health. The only factor that could predict higher sexual dysfunction in WWE was higher seizure frequency.

Seizure control in women with epilepsy undergoing assisted reproductive technology.

The objective of this study was to determine seizure control in women with epilepsy (WWE) undergoing assisted reproductive technology (ART). Through retrospective chart review, WWE undergoing ART were identified. Demographics and details regarding epilepsy type, seizure control, and ART procedures were extracted. Seizure frequency prior to and during ART were compared. We identified 12 WWE, who underwent 29 embryo transfers, resulting in 16 pregnancies and 10 live births. Nine women were seizure-free at least 2 years before fertility treatment, including three with resolved epilepsy. Seven were on antiseizure medications throughout fertility treatment and pregnancy, with only one on polytherapy. Eleven (all with controlled epilepsy or epilepsy in remission) remained seizure-free throughout fertility treatment. One woman with drug-resistant epilepsy continued to have seizures throughout fertility treatment and pregnancy without an exacerbation of seizure frequency. There was no increased seizure frequency associated with fertility treatment and subsequent pregnancy in this small series of WWE. Although this study was statistically underpowered, our results provide some preliminary evidence that ART might not pose a threat to seizure control, but larger, confirmatory studies are necessary.

Pregnancy characteristics and adverse outcomes in offspring of women with epilepsy: a prospective registry study from Mainland China.

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.

External validation of the AntiEpileptic Drug Monitoring in PREgnancy (EMPiRE) model for predicting seizures in pregnant women with epilepsy.

BACKGROUND: The AntiEpileptic Drug Monitoring in PREgnancy (EMPiRE) model is the only available tool for predicting seizures in pregnant women with epilepsy (WWE) using anti-seizure medications (ASMs); however, its predictive performance requires validation. This study aimed to evaluate the predictive ability of this model in pregnant Chinese WWE and its potential usefulness in clinical practice. METHODS: Data of the EMPiRE model were derived from the EMPiRE study, a prospective multicenter cohort study that recruited women on ASM monotherapy (lamotrigine, carbamazepine, phenytoin or levetiracetam) or polytherapy (lamotrigine with either carbamazepine, phenytoin or levetiracetam). Based on the applicable population of the EMPiRE model, we evaluated 280 patients registered in the Wenzhou Epilepsy Follow-up Registry Database from January 1, 2010, to December 31, 2020. A total of 158 eligible patients were included in the validation cohort. We collected data on the baseline characteristics of patients, eight predictors of the EMPiRE model and outcome events. The outcome was the occurrence of tonic-clonic or non-tonic-clonic seizures at any time in pregnancy up to 6 weeks postpartum. We used the equation of the EMPiRE model to obtain the predicted probabilities of seizures. The predictive ability of the EMPiRE model was quantified by the C-statistic (scale 0-1, values > 0.5 show discrimination), GiViTI calibration test and decision curve analysis (DCA). RESULTS: Of 158 eligible patients, 96 patients (60.8%, 96/158) experienced one or more seizures at any time between pregnancy and 6 weeks postpartum. The EMPiRE model showed good discrimination with a C-statistic of 0.76 (95% confidence interval [CI] 0.70-0.84). The GiViTI calibration belt showed that the predicted probabilities, which ranged from 16 to 96% (95% CI), were lower than the actual probabilities. DCA indicated that the highest net proportional benefit was obtained for predicted probability thresholds of 15-18% and 54-96%. CONCLUSIONS: The EMPiRE model could discriminate well between WWE with and without seizures during pregnancy and 6 weeks postpartum, but the risk of seizures may be underestimated. The limitations of the model for specific medication regimens may limit its real-world application. If the model is further improved, it will be incredibly valuable.
