Ura H, Matsuoka N, Kubota K, Sadamoto K. Trends in prescription of anti-seizure medications in Japan between 2018 and 2021: A retrospective study using the National Database Open Data Japan. Epilepsy Behav 2024; 159:109949. [PMID: 39121754 DOI: 10.1016/j.yebeh.2024.109949] [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: 05/06/2024] [Revised: 06/13/2024] [Accepted: 07/14/2024] [Indexed: 08/12/2024]
Abstract
PURPOSE This retrospective study aimed to analyze anti-seizure medication (ASM) prescription trends in Japan, particularly among older adults and women of childbearing age, to inform future treatment strategies and optimize ASM selection criteria. METHODS Data were extracted from the National Database Open Data Japan for fiscal years (FY) 2018-2021, covering prescriptions across sex and 5-year age groups. We conducted data imputation for prescriptions under 1,000 units to maintain anonymity, calculated the estimated number of patients using standard adult maintenance doses, and adjusted for pediatric dosing using Augsberger's formula. RESULTS Our analysis revealed a 7.6% increase in ASM usage, with a notable shift from older to newer ASMs, such as levetiracetam (LEV) and lamotrigine (LTG). LEV and LTG prescriptions increased by 26.7% and 15.0% from FY 2018 to FY 2021, respectively, whereas older ASMs such as phenytoin, declined. Sex-specific analysis showed a higher LTG prescription rate among women, especially in adolescent and young adult cohorts, where the female-to-male prescription ratio increased from 1.65 to 1.85. Valproate (VPA) and LEV accounted for 57.0% of ASM prescriptions in older adults. The number of inpatient LTG prescriptions was notably lower than that of outpatient LTG prescriptions across age groups. Pediatric use of generics was lower than that in other age groups. CONCLUSION This study revealed that newer ASMs are being used increasingly, with a significant proportion of VPA continuously prescribed among women of childbearing age. In older adults, VPA and LEV accounted for more than half of the ASM prescriptions. These findings are crucial for developing future treatment strategies and improving the ASM selection criteria.

Treatment patterns in women of childbearing age and pregnant women with epilepsy in Poland between the years 2019 and 2022-A nationwide population-based cohort study. Seizure 2024; 115:75-80. [PMID: 38232647 DOI: 10.1016/j.seizure.2024.01.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 12/25/2023] [Accepted: 01/11/2024] [Indexed: 01/19/2024] Open
Abstract
AIM To describe the antiseizure medications (ASMs) prescription pattern in women of childbearing age (WOCA) and pregnant women with epilepsy in the 2019-2022 period in Poland MATERIALS AND METHODS: The National Health Fund (NHF) databases were analyzed. Women aged 15-49 years were considered as being of childbearing age, while exposure during pregnancy was estimated taking into account 15 months before delivery. ASMs belonging to the N03A subgroup of the Anatomical Therapeutic Chemical Classification System, reimbursed by NHF were analyzed. RESULTS During 2019, 36 784 WOCA and 921 pregnant women filled at least 1 ASM prescription. In 2022, these numbers were 32 304 and 594, respectively. Valproate was the most widely used ASM in WOCA (38.4 %) in 2019, followed by levetiracetam (35.6 %), lamotrigine (30.1 %), and carbamazepine (20.0 %). The percentage of ASM users decreased in 2022 for valproate (32.1 %; p < 0.001) and carbamazepine (17 %; p < 0.001) and increased for levetiracetam (40.8 %; p < 0.001) and lamotrigine (32.7 %; p < 0.001). In 2019 lamotrigine (42.1 %) and levetiracetam (41.5 %) were the most frequently prescribed ASMs to pregnant women. During the study period, a significant increase in prescriptions for levetiracetam was observed (49.5 %; p = 0.003). The proportion of ASMs exposed pregnancies declined for valproate (from 24.7 to 16 %; p < 0.001) and topiramate (from 6.6 to 3.2 %; p = 0.005). The percentage of polytherapy regimens remained stable over the years, both for WOCA (39 %) and pregnant women (32 %). CONCLUSION Despite the decline in valproate usage, the drug was still among the most commonly prescribed ASMs in women of childbearing age and pregnant women with epilepsy. The awareness of teratogenic risks and new treatment guidelines should be improved in Poland.

Abstract
Importance The association of fetal exposure to antiseizure medications (ASMs) with outcomes in childhood are not well delineated. Objective To examine the association of fetal ASM exposure with subsequent adaptive, behavioral or emotional, and neurodevelopmental disorder outcomes at 2, 3, and 4.5 years of age. Design, Setting, and Participants The Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study is a prospective, observational cohort study conducted at 20 epilepsy centers in the US. A total of 456 pregnant women with epilepsy or without epilepsy were enrolled from December 19, 2012, to January 13, 2016. Children of enrolled women were followed up with formal assessments at 2, 3, 4.5, and 6 years of age. Statistical analysis took place from August 2022 to May 2023. Exposures Exposures included mother's epilepsy status as well as mother's ASM blood concentration in the third trimester (for children of women with epilepsy). Women with epilepsy were enrolled regardless of ASM regimen. Main Outcomes and Measures The primary outcome was the Adaptive Behavior Assessment System, Third Edition (ABAS-3) General Adaptive Composite (GAC) score among children at 4.5 years of age. Children of women with epilepsy and children of women without epilepsy were compared, and the associations of ASM exposures with outcomes among exposed children were assessed. Secondary outcomes involved similar analyses of other related measures. Results Primary analysis included 302 children of women with epilepsy (143 boys [47.4%]) and 84 children of women without epilepsy (45 boys [53.6%]). Overall adaptive functioning (ABAS-3 GAC score at 4.5 years) did not significantly differ between children of women with epilepsy and children of women without epilepsy (parameter estimate [PE], 0.4 [95% CI, -2.5 to 3.4]; P = .77). However, in adjusted analyses, a significant decrease in functioning was seen with increasing third-trimester maximum ASM blood concentrations (PE, -7.8 [95% CI, -12.6 to -3.1]; P = .001). This decrease in functioning was evident for levetiracetam (PE, -18.9 [95% CI, -26.8 to -10.9]; P < .001) and lamotrigine (PE, -12.0 [95% CI, -23.7 to -0.3]; P = .04), the ASMs with sample sizes large enough for analysis. Results were similar with third-trimester maximum daily dose. Conclusions and Relevance This study suggests that adaptive functioning of children of women with epilepsy taking commonly used ASMs did not significantly differ from that of children of women without epilepsy, but there was an exposure-dependent association of ASMs with functioning. Thus, psychiatric or psychological screening and referral of women with epilepsy and their offspring are recommended when appropriate. Additional research is needed to confirm these findings.

Abstract
Cognitive Outcomes at Age 3 Years in Children With Fetal Exposure to Antiseizure Medications (MONEAD Study) in the USA: A Prospective, Observational Cohort Study Meador KJ, Cohen MJ, Loring DW, Matthews AG, Brown C, Robalino CP, Birnbaum AK, Voinescu PE, Kalayjian LA, Gerard EE, Gedzelman ER, Hanna J, Cavitt J, Sam M, French JA, Hwang S, Pack AM, Pennell PB; MONEAD Investigator Group. Lancet Neurol . 2023;22(8):712-722. doi:10.1016/S1474-4422(23)00199-0 Background: The neurodevelopmental effects of fetal exposure to most antiseizure medications are unclear. We aimed to investigate the effects of fetal exposure to commonly used antiseizure medications on neuropsychological outcomes at age 3 years. Methods: The Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study is a prospective, observational, multicenter cohort study at 20 specialty epilepsy centers in the USA. We have investigated pregnancy outcomes in women (aged 14-45 years) with and without epilepsy who were enrolled during pregnancy (≤20 weeks’ gestational age), and their children. The primary outcome for children at age 3 years was a blindly assessed Verbal Index score, which was calculated by averaging scores on the Naming Vocabulary and Verbal Comprehension subtests of Differential Ability Scales-II, Expressive Communication and Auditory Comprehension subscales of Preschool Language Scale-5, and Peabody Picture Vocabulary Test-4. Children of women with and without epilepsy were compared, and the associations of medication exposures to outcomes in exposed children were assessed. The MONEAD study is registered with ClinicalTrials.gov, NCT0730170, and is ongoing. Findings: Between Dec 19, 2012, and Jan 13, 2016, 456 pregnant women (351 with epilepsy and 105 without epilepsy) were enrolled into the study. 345 children were born to women with epilepsy and 106 children were born to women without epilepsy. Verbal Index scores at age 3 years did not differ for children of women with epilepsy (n = 284; adjusted least-square mean 102.7, 95% CI 101.4 to 103.9) versus those without epilepsy (n = 87; 102.3, 99.8 to 104.7). Significant risk factors for reduced Verbal Index scores included maternal intelligence quotient, maternal education, post-birth anxiety, gestational age at enrolment, child’s sex, and child’s ethnicity. For Verbal Index scores, antiseizure medication exposure effects were not seen for maximum third trimester blood concentrations (n = 258; adjusted parameter estimate −2.9, 95% CI −6.7 to 1·0). However, in secondary analyses, exposure-dependent effects were present on multiple cognitive measures, which varied by medication. Interpretation: We found no difference in neurodevelopmental outcomes between children with fetal exposure to newer antiseizure medications compared with unexposed children. However, some exposure-dependent antiseizure medication effects were seen in secondary analyses. The adverse effects of maternal post-birth anxiety emphasize the importance of screening mothers during pregnancy and postpartum and implementing interventions. Additional studies are needed to clarify the exposure-dependent effects.

Abstract
OBJECTIVE Antiseizure medications (ASMs) are frequently used for other indications, such as migraine, pain syndromes, and psychiatric disorders. Possible teratogenic effects are therefore of wide concern and the risks imposed by the medications must be weighed against the risk with the disorder treated. It is our objective to update family practitioners on the implications of starting ASM for women with epilepsy during childbearing age. We hypothesized that clinicians would prescribe ASM based on avoiding teratogenesis and treating associated comorbidities simultaneously. METHODS The study cohort was derived from women veterans with epilepsy (WVWE) prescribed ASM who received Veterans Health Administration care for at least 3 years in Veterans Health Administration between fiscal years (FY)01 and FY19. Regimens were classified as monotherapy or polytherapy. Multivariant logistic regression examined the association between demographics, military characteristics, physical/psychiatric comorbidities, neurological care, and use of each ASM. RESULTS Among 2,283 WVWE, in ages between 17 and 45, the majority (61%) received monotherapy in FY19. Commonly prescribed ASM included 29% gabapentin, 27% topiramate, 20% lamotrigine, 16% levetiracetam, and 8% valproate (VPA). Comorbid diagnosis of headache predicted use of topiramate and VPA, bipolar disease predicted use of LMT and VPA, pain predicted gabapentin, and schizophrenia was associated with VPAs use. Women receiving levetiracetam and lamotrigine were significantly more likely to receive neurology care previously. CONCLUSION The presence of medical comorbidities influences the selection of ASM. VPAs use in WVWE during childbearing age continues, despite the high teratogenic risk, especially in women with bipolar disorder and headaches. Multidisciplinary care integrating family practice doctors, mental health, and neurology can prevent the enduring problem of teratogenesis in women taking ASM.

Neurology 2023; 101:e1083-e1096. [PMID: 37407266 PMCID: PMC10491435 DOI: 10.1212/wnl.0000000000207580] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 05/10/2023] [Indexed: 07/07/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Antiseizure medications (ASMs) are among the most commonly prescribed teratogenic drugs in women of childbearing age. Limited data exist on utilization patterns across different indications for therapy and for the newer-generation ASMs in this population. Thus, we assessed the pattern of ASM use in women of childbearing age with epilepsy and nonepilepsy indications (pain and psychiatric disorders). METHODS We conducted a retrospective analysis of deidentified administrative data submitted to the Optum Clinformatics database. Eligible participants included women aged 12-50 years who filled ASMs between year 2011 and 2017. Participants were followed from date of index prescription filled to study end or insurance disenrollment, whichever came first. For the overall cohort and potential therapy indications, we assessed the type and frequency of ASMs filled; proportion of participants on monotherapy, polytherapy, or treatment switching; and duration of continuous use. Trends were characterized using annual percent change from study start to study end. RESULTS Our analysis included 465,131 participants who filled 603,916 distinct ASM prescriptions. At baseline, most of the participants had chronic pain (51.0%) and psychiatric disorders (32.7%), with epilepsy the least common (0.9%). The most frequently dispensed were diazepam (24.3%), lorazepam (20.1%), gabapentin (17.4%), clonazepam (12.7%), topiramate (11.3%), and lamotrigine (4.6%). Significant linear increase in trends were observed with gabapentin (annual percent change [95% CI]: 8.4 [7.3-9.4]; p < 0.001) and levetiracetam (3.4 [0.7-6.2]; p = 0.022) and decreasing trends for diazepam (-3.5 [-2.4 to 4.5]; p < 0.001) and clonazepam (-3.4 [-2.3 to 4.5]; p = 0.001). No significant change in trend was observed with valproate (-0.4 [-2.7 to 1.9]; p = 0.651), while nonlinear changes in trends were observed with lorazepam, topiramate, lamotrigine, and pregabalin. DISCUSSION Decreasing trends were observed with older ASMs in the overall cohort and across the potential indications for therapy. Conversely, increasing trends were seen with the newer ASMs. Considering the risk of teratogenicity associated with the newer medications largely unknown, counseling and education in addition to a careful consideration of the benefits vs potential risks should remain pivotal when prescribing ASMs for women of childbearing age.

Abstract
The placenta is a critical organ for fetal development and a healthy pregnancy, and has multifaceted functions (e.g., substance exchange and hormone secretion). Syncytialization of trophoblasts is important for maintaining placental functions. Epilepsy is one of the most common neurological conditions worldwide. Therefore, this study aimed to reveal the influence of antiepileptic drugs, including valproic acid (VPA), carbamazepine, lamotrigine, gabapentin, levetiracetam, topiramate, lacosamide, and clobazam, at clinically relevant concentrations on syncytialization using in vitro models of trophoblasts. To induce differentiation into syncytiotrophoblast-like cells, BeWo cells were treated with forskolin. Exposure to VPA was found to dose-dependently influence syncytialization-associated genes (ERVW-1, ERVFRD-1, GJA1, CGB, CSH, SLC1A5, and ABCC4) in differentiated BeWo cells. Herein, the biomarkers between differentiated BeWo cells and the human trophoblast stem model (TSCT) were compared. In particular, MFSD2A levels were low in BeWo cells but abundant in TSCT cells. VPA exposure affected the expression of ERVW-1, ERVFRD-1, GJA1, CSH, MFSD2A, and ABCC4 in differentiated cells (ST-TSCT). Furthermore, VPA exposure attenuated BeWo and TSCT cell fusion. Finally, the relationships between neonatal/placental parameters and the expression of syncytialization markers in human term placentas were analyzed. MFSD2A expression was positively correlated with neonatal body weight, head circumference, chest circumference, and placental weight. Our findings have important implications for better understanding the mechanisms of toxicity of antiepileptic drugs and predicting the risks to placental and fetal development.

Abstract
Background Ambulatory electroencephalography (AEEG) recording is an essential aid for detecting interictal discharges and providing a clinical diagnosis. This study aimed to describe long-term outcomes among a cohort of patients who yielded negative results on AEEG at the time of assessment and identify factors associated with contemporary quality of life (QOL) and ultimate epilepsy diagnosis. Methods This cross-sectional telephone follow-up study was conducted in June-November 2021 at the Neurology Department in a metropolitan hospital in Sydney, Australia. Results In total, 47 of 105 eligible (45%) participants were enrolled. Overall, 21 (45%) participants had been diagnosed with epilepsy at a 12-year follow-up. Taking anti-seizure medication, having experienced a seizure event, and having marriage and education-related characteristics were associated with an epilepsy diagnosis. QOL was found to be associated with age, employment status and history of experience of a seizure event. QOL and an epilepsy diagnosis were not shown to be statistically related. Conclusions Nearly half of the participants had received an epilepsy diagnosis at long-term follow-up, despite having tested negative on AEEG at the time of assessment. Prolonged AEEG testing is an important tool to aid the diagnostic process. However, clinical examination, including accurate history taking, is vital in establishing an epilepsy diagnosis.

Abstract
BACKGROUND The neurodevelopmental effects of fetal exposure to most antiseizure medications are unclear. We aimed to investigate the effects of fetal exposure to commonly used antiseizure medications on neuropsychological outcomes at age 3 years. METHODS The Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study is a prospective, observational, multicentre cohort study at 20 specialty epilepsy centres in the USA. We have investigated pregnancy outcomes in women (aged 14-45 years) with and without epilepsy who were enrolled during pregnancy (≤20 weeks' gestational age), and their children. The primary outcome for children at age 3 years was a blindly assessed Verbal Index score, which was calculated by averaging scores on the Naming Vocabulary and Verbal Comprehension subtests of Differential Ability Scales-II, Expressive Communication and Auditory Comprehension subscales of Preschool Language Scale-5, and Peabody Picture Vocabulary Test-4. Children of women with and without epilepsy were compared, and the associations of medication exposures to outcomes in exposed children were assessed. The MONEAD study is registered with ClinicalTrials.gov, NCT0730170, and is ongoing. FINDINGS Between Dec 19, 2012, and Jan 13, 2016, 456 pregnant women (351 with epilepsy and 105 without epilepsy) were enrolled into the study. 345 children were born to women with epilepsy and 106 children were born to women without epilepsy. Verbal Index scores at age 3 years did not differ for children of women with epilepsy (n=284; adjusted least-square mean 102·7, 95% CI 101·4 to 103·9) versus those without epilepsy (n=87; 102·3, 99·8 to 104·7). Significant risk factors for reduced Verbal Index scores included maternal intelligence quotient, maternal education, post-birth anxiety, gestational age at enrolment, child's sex, and child's ethnicity. For Verbal Index scores, antiseizure medication exposure effects were not seen for maximum third trimester blood concentrations (n=258; adjusted parameter estimate -2·9, 95% CI -6·7 to 1·0). However, in secondary analyses, exposure-dependent effects were present on multiple cognitive measures, which varied by medication. INTERPRETATION We found no difference in neurodevelopmental outcomes between children with fetal exposure to newer antiseizure medications compared with unexposed children. However, some exposure-dependent antiseizure medication effects were seen in secondary analyses. The adverse effects of maternal post-birth anxiety emphasise the importance of screening mothers during pregnancy and postpartum and implementing interventions. Additional studies are needed to clarify the exposure-dependent effects.

Abstract
BACKGROUND This narrative review aims to discuss several common neurological and psychiatric disorders that show comorbidity with migraine. Not only can we gain pathophysiological insights by studying these disorders, comorbidities also have important implications for treating migraine patients in clinical practice. METHODS A literature search on PubMed and Embase was conducted with the keywords "comorbidity", "migraine disorders", "migraine with aura", "migraine without aura", "depression", "depressive disorders", "epilepsy", "stroke", "patent foramen ovale", "sleep wake disorders", "restless legs syndrome", "genetics", "therapeutics". RESULTS Several common neurological and psychiatric disorders show comorbidity with migraine. Major depression and migraine show bidirectional causality and have shared genetic factors. Dysregulation of both hypothalamic and thalamic pathways have been implicated as a possibly cause. The increased risk of ischaemic stroke in migraine likely involves spreading depolarizations. Epilepsy is not only bidirectionally related to migraine, but is also co-occurring in monogenic migraine syndromes. Neuronal hyperexcitability is an important overlapping mechanism between these conditions. Hypothalamic dysfunction is suggested as the underlying mechanism for comorbidity between sleep disorders and migraine and might explain altered circadian timing in migraine. CONCLUSION These comorbid conditions in migraine with distinct pathophysiological mechanisms have important implications for best treatment choices and may provide clues for future approaches.

Abstract
AIMS The pharmacokinetics of levetiracetam (LEV) significantly changed during pregnancy. It is a great challenge to predict the adjusted doses of LEV to reach the preconception target concentrations. This study aimed to establish a population pharmacokinetic model of LEV in women with epilepsy (WWE) during pregnancy to analyse the factors of pharmacokinetic variability and to develop a model-based individualized dosing regimen. METHODS A total of 166 concentration-time points from 37 WWE during pregnancy treated with LEV were collected to analyse LEV pharmacokinetics with nonlinear mixed-effects modelling. The dosing regimen was optimized by Monte Carlo simulations based on the final model. RESULTS The LEV pharmacokinetics in pregnant WWE were best described by a 1-compartment model of first-order absorption and elimination. The population typical value of apparent clearance (CL/F) in the final model was estimated to be 3.82 L/h (95% confidence interval 3.283-4.357 L/h) with a relative standard error of 7.2%. Both total body weight (TBW) and trimester of pregnancy were significantly associated with LEV-CL/F during pregnancy; LEV-CL/F increased by 42.72% when TBW increased from 55 to 65 kg from the first trimester to the second trimester. Monte Carlo simulations showed that dosing regimens for LEV should be individualized based on the patient's TBW and trimester of pregnancy to maximize the likelihood of achieving the therapeutic range. CONCLUSION This first population pharmacokinetic study of LEV in WWE during pregnancy supports the use of a weight-based and pregnancy-based dosing regimen and can lay a foundation for further optimizing the individualized dosing regimens.

Abstract
BACKGROUND AND OBJECTIVES To investigate whether children born to mothers who used carbamazepine during pregnancy had worse academic performance in adolescence. METHODS This population-based cohort study included all live-born singletons in Denmark between 1996 and 2002 who participated in the national ninth-grade exit examination (n = 370,859). Those born to mothers with prescription of antiseizure medications other than carbamazepine during pregnancy were excluded. We examined the association of in utero exposure to maternal carbamazepine redeemed during pregnancy (n = 290) with academic performance of offspring, defined by the scores in Danish and mathematics in ninth-grade exit examination. We estimated mean z-score difference with linear regression adjusted for socioeconomic factors and potential indications, including epilepsy and medication for other psychiatric disorders. Additional analyses addressing confounding by indication included comparison between in utero exposed vs past exposed and between past exposed and never exposed. In utero exposure to valproate monotherapy was used as a positive control and in utero exposure to lamotrigine as a negative control. RESULTS At the age of 16.1 (SD 0.4) years, adolescents in utero exposed to maternal carbamazepine monotherapy had lower scores both in Danish and mathematics in ninth-grade exit examination (adjusted z-score difference, -0.14 [95% CI -0.24 to -0.05] and -0.17 [95% CI -0.28 to -0.07], respectively). In utero exposure to carbamazepine monotherapy was associated with lower scores than past exposure only (adjusted z-score difference, -0.24 [95% CI -0.41 to -0.06] for Danish and -0.25 [95% CI -0.44 to -0.06] for mathematics), while past exposure to carbamazepine was associated with minor decrease in offspring's academic performance (adjusted z-score difference, -0.02 [95% CI -0.09 to 0.06] for Danish and -0.07 [95% CI -0.16 to 0.01] for mathematics). The association was also observed for in utero exposure to valproate monotherapy, but not for in utero exposure to lamotrigine. DISCUSSION In utero exposure to carbamazepine was associated with poorer academic performance in adolescence, as represented by lower scores in ninth-grade exit examination in Danish and mathematics. Additional studies are needed to confirm these findings because of limitations in this study and variable findings in prior studies. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that academic performance, as reflected in ninth-grade exit examinations in Danish and mathematics, was worse among those exposed to carbamazepine monotherapy in utero, compared with those without in utero exposure to antiseizure medications.

Epilepsy Behav 2023; 139:109091. [PMID: 36682232 DOI: 10.1016/j.yebeh.2023.109091] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 01/01/2023] [Accepted: 01/05/2023] [Indexed: 01/21/2023]
Abstract
PURPOSE To determine trends in the use of antiseizure medications (ASMs) among women of childbearing age (WOCA) and girls aged 12-14 years with epilepsy between 2015 and 2019 in Poland. METHODS The study used data from the Pex database, which captures information on prescriptions dispensed from 85% of community pharmacies in Poland. The prescriptions issued by neurologists who provide epilepsy care in Poland were studied. Six of the most commonly prescribed ASMs were analyzed: carbamazepine, lamotrigine, levetiracetam, oxcarbazepine, topiramate, and valproate. RESULTS The use of valproate and carbamazepine decreased in all age groups. Among the newer ASMs, the use of lamotrigine, levetiracetam, and topiramate increased and oxcarbazepine decreased significantly in WOCA. The only subgroup with statistically significant changes in all ASMs prescriptions were women aged 19-34 years. For girls aged 12-14 years, significant changes were found only for valproate and carbamazepine. In the last year of observation (2019) valproate and lamotrigine accounted for two-thirds of ASMs units prescribed to WOCA. Valproate accounted for half of the prescribed drug units in girls aged 12-14 years. The lowest rates of VPA prescriptions were found in women aged 19-34 years. CONCLUSIONS There is a change in prescribing habits in WOCA with epilepsy in Poland with trends toward using less teratogenic ASMs. However, many WOCAs are treated with valproate and topiramate despite their known teratogenicity risk. Valproate is still the most commonly prescribed ASM in WOCA and girls aged 12-14 years. Educational interventions for healthcare professionals are needed to improve prescribing practices in WOCA with epilepsy in Poland.

Abstract
Management of seizures often involves continuous medication use throughout a patient's life, including when a patient is pregnant. The physiological changes during pregnancy can lead to altered drug exposure to anti-seizure medications, increasing patient response variability. In addition, subtherapeutic anti-seizure medication concentrations in the mother may increase seizure frequency, raising the risk of miscarriage and preterm labor. On the other hand, drug exposure increases can lead to differences in neurodevelopmental outcomes in the developing fetus. Established pregnancy registries provide insight into the teratogenicity potential of anti-seizure medication use. In addition, some anti-seizure medications are associated with an increased risk of major congenital malformations, and their use has declined over the last decade. Although newer anti-seizure medications are thought to have more favorable pharmacokinetics in general, they are not without risk, as they may undergo significant pharmacokinetic changes when an individual becomes pregnant. With known changes in metabolism and kidney function during pregnancy, therapeutic monitoring of drug concentrations helps to determine if and when doses should be changed to maintain similar seizure control as observed pre-pregnancy. This review concentrates on the results from research in the past decade (2010-2022) regarding risks of major congenital malformations, changes in prescribing patterns, and pharmacokinetics of the anti-seizure medications that are prescribed to pregnant patients with epilepsy.

Abstract
BACKGROUND AND AIMS Topiramate is a medication that is widely prescribed to treat a variety of conditions, including alcohol use disorder (AUD). We used electronic health record (EHR) data to measure topiramate's effects on drinking in individuals differentiated by a history of AUD. DESIGN Parallel-groups comparison of patients prescribed topiramate and a propensity score-matched comparison group. SETTING A large US integrated health-care system. PARTICIPANTS Patients with Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) scores prior to and after a minimum of 180 days of topiramate prescription for any indication and a propensity score-matched group. The sample included 5918 patients with an electronic health record diagnosis of alcohol use disorder at any time (AUD-hx-pos) (1738 topiramate-exposed and 4180 controls) and 23 614 patients with no EHR diagnosis of AUD (AUD-hx-neg) (6324 topiramate-exposed and 17 290 controls). MEASUREMENTS Regression analyses compared difference-in-difference (DiD) estimates, separately by AUD history. DiD estimates represent exposure-group (i.e. topiramate versus control) differences on the pre-post difference in AUDIT-C score. Effects of baseline AUDIT-C score and daily topiramate dosage were also tested. FINDINGS AUD-hx-neg patients who received topiramate had a greater reduction in AUDIT-C score (-0.11) than matched controls (-0.04). This yielded a DiD score of -0.07 [95% confidence interval (CI) = -0.11,-0.03; P = 0.002], with the greatest effect among AUD-hx-neg patients with a baseline AUDIT-C score of 4+ (DiD = -0.35, 95% CI = -0.49, -0.21; P < 0.0001) and those prescribed > 150 mg/day of the medication (DiD = -0.15, 95%CI = -0.23, -0.07; P < 0.001). DISCUSSION Among individuals with no history of alcohol use disorder, topiramate appears to be associated with reduced drinking. This small effect is most evident among patients with higher baseline drinking levels and at a higher average daily topiramate dosage.

Abstract
OBJECTIVE Valproate has undergone significant changes in labeling to the boxed warnings associated with it. This review will analyze evidence regarding the valproate-boxed warnings for teratogenicity, hepatotoxicity, and pancreatitis, with a particular emphasis on the fetal risk. DATA SOURCES A review of Pubmed, Cochrane Central Register, Google Scholar, manufacturer websites, and product labeling was performed from 1963 to February 2022, using the following search terms: valproate, valproic acid, depakote, teratogenicity, birth defects, fetal risk, hepatotoxicity, and pancreatitis. Relevant English-language studies and those conduced in humans were considered. Product labeling was also reviewed. DATA SYNTHESIS There is a significant fetal risk following in utero valproate exposure (risk of malformation development: 8.6% in 360 women in North America). Current labeling in the United States recommends co-prescribing effective contraception for women of childbearing age. The risk of hepatotoxicity and pancreatitis is much lower in the general population (1/20 000 and 1/40 000 patients, respectively) compared with those patients with certain risk factors who are taking valproate (1/500). CONCLUSIONS Overstated monitoring recommendations for the potential risk of hepatotoxicity and pancreatitis distracts from a much more common and severe risk of fetal harm. Clinicians must be diligent about discussing this risk with patients and documenting when this discussion occurs. Changes to the current recommendations for monitoring of the boxed warnings associated with valproate therapy should be considered, such as more stringent monitoring requirements for the inherent fetal risk. This could be accomplished through a Risk Evaluation and Mitigation Strategy program or through institution-based policies and procedures. In addition, monitoring recommendations for the risk of hepatotoxicity and pancreatitis should account for contributing risk factors.

Abstract
OBJECTIVE This qualitative explorative study was conducted to explore the key challenges and future directions of caring for women with epilepsy (WWE) from the perspectives of healthcare professionals who provide care for WWE in Palestine. METHODS A qualitative explorative design was used in this study in adherence to the consolidated criteria for reporting qualitative research. The study participants were interviewed in semi-structured in-depth interviews using a pre-validated and pilot-tested interview schedule. The interpretative description approach was used to qualitatively analyze the contents of the interviews. RESULTS Interviews were conducted with 6 neurologists, 5 gynecologists, 3 psychiatrists, 5 clinical pharmacists, and 1 internal medicine specialist. The current challenges and future directions in caring for WWE were grouped under healthcare system-, healthcare provider-, patient-, and society-related. Lack of adequate availability, accessibility, and affordability of neurology services and safe antiepileptic drugs (AEDs) were the main challenges. Increasing access of WWE to specialized neurology services and improving acceptance in the society were the main future directions. CONCLUSION Findings of this study highlighted the key challenges and future directions of caring for WWE in a resource-poor healthcare system. Decision makers in health authorities, professional bodies, and patient advocacy groups should consider improving availability, accessibility, and affordability of neurology services and safe AEDs for WWE. Future studies are still needed to investigate if addressing these challenges can improve the care of WWE in Palestine.

Abstract
The aim of this study was to provide real-world data on clinical characteristics, risk factors, and treatment patterns in Indian patients with epilepsy. Electronic medical record (EMR) data of patients diagnosed with epilepsy between January 2001 and December 2019, which included demographics, diagnosis, anti-epileptic drug usage, and underlying risk factors were evaluated. The majority of patients were between the age group of 18 and 55 years (n=3,186), with males accounting for 62% and the remaining 38% being females. Further, the most common comorbidity was hypertension (23.3%, n=1,470), followed by diabetes mellitus (10.8%, n=683) and depression (9.4%, n=597). The most prevalent form of epilepsy was focal epilepsy (n=5,141 81.4%), followed by generalized epilepsy (n=601). Focal epilepsy was most prevalent in males (62%, n=3,167) and most common in the age group of 18-55 years (50.3%, n=2588). Anti-epileptic drug (AED) usage data from 6,318 patients showed that the most commonly prescribed AED alone or in combination for both focal and generalized epilepsy was levetiracetam (41.8%, n= 2645). Data collected from this study are aligned but do not completely agree with the Guidelines for the Management of Epilepsy in India (GEMIND). This affirms treatment initiation with AED monotherapy; however, the treatment choices do not necessarily follow the recommended guidelines to select conventional AEDs, at low strengths, at initiation.

[PMID: 35387387 PMCID: PMC8977694 DOI: 10.1177/20420986221088419] [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: 08/20/2021] [Accepted: 03/02/2022] [Indexed: 11/15/2022] Open
Abstract
Some old antiseizure medications (ASMs) pose teratogenic risks, including major
congenital malformations and neurodevelopmental delay. Therefore, the use of new
ASMs in pregnancy is increasing, particularly lamotrigine and levetiracetam.
This is likely due to evidence of low risk of anatomical teratogenicity for both
lamotrigine and levetiracetam. Regarding neurodevelopmental effects, lamotrigine
is the most frequently investigated new ASM with information available for
children up to 14 years of age. However, fewer data are available for the
effects of levetiracetam on cognitive and behavioral development, with smaller
cohorts and shorter follow-up. The aim of the present review was to explicate
neurodevelopmental outcomes in children exposed prenatally to levetiracetam to
support clinical decision-making. The available data do not indicate an
increased risk of abnormal neurodevelopmental outcomes in children exposed
prenatally to levetiracetam. Findings demonstrated comparable outcomes for
levetiracetam versus controls and favorable outcomes for
levetiracetam versus valproate on global and specific cognitive
abilities, and behavioral problems. In addition, the available evidence shows no
significant dose-effect association for levetiracetam on neurodevelopmental
outcomes. However, this evidence cannot be determined definitively due to the
limited numbers of exposures with relatively short follow-up. Therefore, further
research is required.

Shawahna R, Zaid L. Concentrations of antiseizure medications in breast milk of lactating women with epilepsy: A systematic review with qualitative synthesis. Seizure 2022; 98:57-70. [PMID: 35427849 DOI: 10.1016/j.seizure.2022.03.017] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2021] [Revised: 03/20/2022] [Accepted: 03/25/2022] [Indexed: 10/18/2022] Open
Abstract
BACKGROUND Recent position papers and guidelines encourage women with epilepsy (WWE) to exclusively breastfeed their infants because the benefits to their infants outweigh the potential adverse effects caused by exposure to antiseizure medications (ASMs). OBJECTIVE The objectives of this review were: to evaluate concentrations of ASMs in breastmilk of lactating WWE, qualitatively synthesize evidence that can be used to estimate theoretical doses as estimated daily intake (EDI) and relative infant dose (RID) of ASMs, and to evaluate potential risks to infants as a result of exposure to ASMs from breastmilk. METHODS This systematic review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) as CRD42020223645. The databases: MEDLINE/PubMed, EMBASE, CINAHL/EBSCO, COCHRANE, SpringerLink, ScienceDirect, Summon, WHO International Clinical Trials Registry Platform, and SCOPUS were systematically searched. A qualitative synthesis was adopted in this study. RESULTS A total of 15 records were included in this systematic review. The included studies reported levels of 8 ASMs in the breastmilk of WWE. The highest RIDs of carbamazepine, lamotrigine, primidone, phenobarbital, gabapentin, valproic acid, ethosuximide, levetiracetam, and topiramate were 3.70%, 36.33%, 4.96%, 3.15%, 4.37%, 1.90%, 31.49%, 12.50%, and 12.18%, respectively. Breastfeeding might be limited or even discontinued when signs of excessive sedation/drowsiness and/or poor weight gain are evident on infants exposed to primidone and phenobarbital, ethosuximide/primidone, or ethosuximide/phenobarbital. CONCLUSIONS Concentrations of ASMs can be detected in breastmilk of WWE and plasma/serum of infants exposed via breastmilk. Healthcare providers and WWE might use the findings of this study to make informed decisions on the safety of breastfeeding while taking ASMs.

Abstract
OBJECTIVE To evaluate severe maternal morbidity (SMM) among patients with epilepsy and patients without epilepsy. METHODS We retrospectively examined SMM using linked birth certificate and maternal hospital discharge records in California between 2007 and 2012. Epilepsy present at delivery admission was the exposure and was subtyped into generalized, focal and other less specified, or unspecified. The outcomes were SMM and nontransfusion SMM from delivery up to 42 days' postpartum, identified using Centers for Disease Control and Prevention indicators. Multivariable logistic regression models were used to adjust for confounders, which were selected a priori. We also estimated the association between epilepsy and SMM independent of comorbidities by using a validated obstetric comorbidity score. Severe maternal morbidity indicators were then compared using the same multivariable logistic regression models. RESULTS Of 2,668,442 births, 8,145 (0.3%) were to patients with epilepsy; 637 (7.8%) had generalized, 6,250 (76.7%) had focal or other less specified, and 1,258 (15.4%) had unspecified subtypes. Compared with patients without epilepsy, patients with epilepsy had greater odds of SMM (4.3% vs 1.4%, adjusted odds ratio [aOR] 2.91, 95% CI 2.61-3.24) and nontransfusion SMM (2.9% vs 0.7%, aOR 4.16, 95% CI 3.65-4.75). Epilepsy remained significantly associated with increased SMM and nontransfusion SMM after additional adjustment for the obstetric comorbidity score, though the effects were attenuated. When grouped by organ system, all SMM indicators were significantly more common among patients with epilepsy-most notably those related to hemorrhage and transfusion. CONCLUSION Severe maternal morbidity was significantly increased in patients with epilepsy, and SMM indicators across all organ systems contributed to this.

Abstract
Phenytoin is a known human teratogen with unknown etiology. Several mechanisms have been proposed including disturbances in folate metabolism, induction of embryonic hypoxia following phenytoin-induced bradycardia, free radical formation following re-oxygenation and phenytoin-induced maternal hyperglycemia. Using high frequency ultrasound, we demonstrated that phenytoin induced a dramatic decrease in the heart rate of embryos. This coincided with a moderate transient decrease in maternal heart rate and blood glucose levels. Embryonic heart rate had not fully recovered 24 h later in some embryos despite normal maternal physiological parameters. In a separate study, extent of hypoxia was measured using the marker pimonidazole. Phenytoin-exposed embryos did not demonstrate increased hypoxia compared to control embryos at 2, 4, 8 or 24 h dosing. Together our results show that phenytoin induces malformations as a result of a combination of insults: embryonic bradycardia, maternal bradycardia and maternal hyperglycemia. However, this does not appear to result in measurable embryonic hypoxia in our animal model.

Analysis of the Clinical Effects of Sodium Valproate and Levetiracetam in the Treatment of Women with Epilepsy during Pregnancy. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:5962200.

Abstract
Objective To explore the clinical effects of sodium valproate and levetiracetam in the treatment of women with epilepsy during pregnancy. Methods The clinical data of 124 women with epilepsy during pregnancy who received monotherapy with antiepileptic drugs (AEDs) in our hospital from September 2017 to January 2020 were retrospectively analyzed. According to the type of medication taken by the patients, they were recorded as the sodium valproate group (the VPA group, n = 56) and the levetiracetam group (the LEV group, n = 68 cases). The effects and the maternal and infant outcomes after treatment were compared between the two groups. The neuron-specific enolase (NSE), cognitive function-related parameters (brain-derived neurotrophic factor (BDNF) and myelin basic protein (MBP)), and related inflammatory factors (tumor necrosis factor- (TNF-) α and interleukin- (IL-) 6) levels were compared between the two groups before and after treatment. Results After treatment, the total clinical effective rate of the LEV group was 91.18% higher than that of the VPA group 73.21%, and the frequency and duration of seizures were lower than those of the VPA group (P < 0.05). After treatment, the probability of gestational hypertension, depression during pregnancy, low-weight infants, and neonatal deformities in the LEV group was lower than that in the VPA group (P < 0.05). After treatment, the levels of NSE, MBP, TNF-α, and IL-6 in the two groups decreased, and the levels of BDNF increased, and the LEV group changed significantly compared with the VPA group (P < 0.05). Conclusion Compared with sodium valproate monotherapy, levetiracetam is more effective in controlling seizures and improving maternal and infant outcomes in women with epilepsy during pregnancy and can effectively regulate their neurological and cognitive functions and reduce the serum inflammation factor level.

Abstract
BACKGROUND Data of large pregnancy registries have improved the recommendations for women with epilepsy before pregnancy. Monotherapy containing antiepileptic drugs with a low malformation rate (lamotrigine or levetiracetam) is recommended as well as preconceptional folic acid supplementation, while valproic acid should be avoided. The practicability of these recommendations remains controversial. METHODS Retrospective case series of 160 women with epilepsy over a period of 5 years who were advised in our outpatient department before and during pregnancy. RESULTS Only 18.9% of women presented with valproic acid. Even without valproic acid, complications or emergency admissions rarely occurred under specialist supervision. In our case series, lamotrigine proved to be less effective and less controllable than other drugs during pregnancy. Levetiracetam also has a low malformation rate, but showed a better effect on seizure outcome during pregnancy than lamotrigine. Only 12% of women who wanted to have children took folic acid. CONCLUSION This case series comes from a tertiary center; the referred women were mainly accompanied by neurologists with special expertise in epileptology. In this group valproate could be avoided in most cases. Lamotrigine is probably less effective due to the drop in blood levels during pregnancy. Levetiracetam seems to be a good alternative, working well against focal and generalized seizures. Folic acid may be taken later than recommended.

Abstract
Importance The neurodevelopmental risks of fetal exposure are uncertain for many antiseizure medications (ASMs). Objective To compare children at 2 years of age who were born to women with epilepsy (WWE) vs healthy women and assess the association of maximum ASM exposure in the third trimester and subsequent cognitive abilities among children of WWE. Design, Setting, and Participants The Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study is a prospective, observational, multicenter investigation of pregnancy outcomes that enrolled women from December 19, 2012, to January 13, 2016, at 20 US epilepsy centers. Children are followed up from birth to 6 years of age, with assessment at 2 years of age for this study. Of 1123 pregnant women assessed, 456 were enrolled; 426 did not meet criteria, and 241 chose not to participate. Data were analyzed from February 20 to December 4, 2020. Main Outcomes and Measures Language domain score according to the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III), which incorporates 5 domain scores (language, motor, cognitive, social-emotional, and general adaptive), and association between BSID-III language domain and ASM blood levels in the third trimester in children of WWE. Analyses were adjusted for multiple potential confounding factors, and measures of ASM exposure were assessed. Results The BSID-III assessments were analyzed in 292 children of WWE (median age, 2.1 [range, 1.9-2.5] years; 155 female [53.1%] and 137 male [46.9%]) and 90 children of healthy women (median age, 2.1 [range, 2.0-2.4] years; 43 female [47.8%] and 47 male [52.2%]). No differences were found between groups on the primary outcome of language domain (-0.5; 95% CI, -4.1 to 3.2). None of the other 4 BSID-III domains differed between children of WWE vs healthy women. Most WWE were taking lamotrigine and/or levetiracetam. Exposure to ASMs in children of WWE showed no association with the language domain. However, secondary analyses revealed that higher maximum observed ASM levels in the third trimester were associated with lower BSID-III scores for the motor domain (-5.6; 95% CI, -10.7 to -0.5), and higher maximum ASM doses in the third trimester were associated with lower scores in the general adaptive domain (-1.4; 95% CI, -2.8 to -0.05). Conclusions and Relevance Outcomes of children at 2 years of age did not differ between children of WWE taking ASMs and children of healthy women.

Abstract
OBJECTIVE Certain antiepileptic drugs are associated with an increased risk for major congenital malformations (MCM). However, little is known regarding recent patterns of antiepileptic drug (ASM) prescriptions to women of childbearing age with epilepsy (WCE) in the United States. METHODS Data from the Medical Expenditure Panel Survey was analyzed between the years 2004-2015 to determine trends in national antiepileptic drug prescriptions for WCE. Analysis of associations between demographic covariates and prescription of ASMs with MCM rate > 5% (topiramate, valproate, or phenobarbital) was performed with logistic regression. RESULTS There was a weighted total of 395,292 WCE. 29.1% (23.2%-35.8%) of WCE were prescribed an AED with MCM rate > 5%. The odds of a LEV prescription significantly increased in the 2010-2012 (OR 2.91, 95% CI 1.09-7.79) and 2013-2015 (OR 5.06, 95% CI 2.02-12.67) intervals compared to 2004-2006. Conversely, the odds of PB prescriptions significantly decreased in 2010-2012 (OR 0.13, 95% CI 0.02-0.83) and 2013-2015 (OR 0.13, 95% CI 0.02-0.93) compared to 2004-2006. WCE between the ages of 25-34 (OR = 2.67, 95% CI = 1.32-5.41) and 35-44 years (OR = 2.59, 95% CI = 1.23-5.45), had lower odds of being prescribed ASMs with MCM rate > 5% compared to those between the ages of 15-24 years. SIGNIFICANCE Between 2004 and 2015, the prescriptions of ASMs given to WCE has changed. Regardless, nearly one third were prescribed potentially teratogenic medications despite available and affordable safer alternatives. Identifying factors associated with the prescription of teratogenic drugs to WCE is critical so that it may be further limited in the future.

Abstract
Avoiding valproate is recommended in women of childbearing age due to possible teratogenicity and infertility. We aimed to examine the recent trend of valproate prescriptions in Korea to review the adequacy of anticonvulsant prescriptions in women with epilepsy (WWE). Oral valproate utilization was assessed using nationwide and unselected data from the Korean National Health Insurance Service from 2009 to 2017. The temporal trends of the proportions of valproate prescriptions were analyzed using the Poisson regression model and expressed as average annual percentage change (AAPC). Among the WWE of childbearing age, valproate was prescribed in 37.0% overall and 29.4% as initial prescription in 2017. The proportion of valproate utilization showed a decreasing trend in overall prescription (AAPC = -1.10%) and initial prescription (AAPC = -2.63%). However, the proportion was static over time in the initial monotherapy group (AAPC = -0. 53%), while it was significantly decreasing in the initial polytherapy group (AAPC = -8.25%). A noticeable proportion of WWE was still being prescribed valproate in Korea. In particular, the use of valproate for initial monotherapy has not decreased over the past nine years. This result calls not only for reinforcement of education regarding anticonvulsant selection but also for monitoring the actual prescription.

Abstract
OBJECTIVE Optimal choice of antiseizure medication (ASM) depends on seizure type, syndrome, age, gender, comorbidities and co-medications. There are no fixed rules on how to weigh these factors; choices are subjective and experience-driven. We investigated agreement among experts in selecting ASM as monotherapy and used their prevailing choices to validate a web-based decision-support application. METHODS Twenty-four international experts, blinded to the app, selected the optimal ASM for 25 individual patient-cases covering a wide variation of seizure types and other factors influencing ASM selection. The app ranked ASMs in order of likely appropriateness for each case. In a second step, experts rated anonymously the choices of the app. RESULTS Of the 25 patient-cases (age 13-74 years), 13 were female, 18 (72%) had comorbidities, six (24%) were on contraceptives, and 13 (52%) had other co-medications. The median number of experts who selected the same ASM for a given case was 15 (62.5%) and interquartile range (IQR) 13-18 (54%-75%). Gwet's agreement coefficient among experts was 0.38 (95% confidence interval [CI] 0.32-0.44), corresponding to a "fair" agreement. Agreement between the app and the prevailing expert choice for each case was 0.48 (95% CI 0.29-0.67), corresponding to a "moderate" beyond chance agreement. The percent agreement between the highest ranked selections of the app and the expert selections was 73% (95% CI 64%-82%). Ninety-five percent of the experts considered that no incorrect or potentially harmful ASMs were ranked highest by the app, and most experts strongly agreed with the app's selections. SIGNIFICANCE This app, now validated by experts, provides an objective, reproducible method for selecting ASM that accounts for relevant clinical features.

Clinical characteristics and fetal outcomes in women with epilepsy with planned and unplanned pregnancy: A retrospective study. Seizure 2020; 79:97-102. [PMID: 32460217 DOI: 10.1016/j.seizure.2020.05.011] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Revised: 05/02/2020] [Accepted: 05/11/2020] [Indexed: 12/14/2022] Open
Abstract
PURPOSE To compare the antiepileptic drug (AED) treatment patterns, seizure control, and folic acid supplementation between planned and unplanned pregnancy in women with epilepsy (WWE) and to investigate the effects of planned pregnancy on fetal outcomes. METHODS A prospectively collected database including WWE with pregnancy from Feb 2010 to Dec 2018 was retrospectively analyzed. Planned pregnancy was defined as WWE being regularly supervised by epileptologists from the time of intended pregnancy until delivery. Clinical characteristics and fetal outcomes were compared between the planned and unplanned pregnancy groups. Logistic regression was used to identify modifiable factors associated with adverse fetal outcomes. RESULTS A total of 188 planned pregnancies and 289 unplanned pregnancies were enrolled in our study. Among planned pregnancies, 66.0 % took AED monotherapy, and 32.4 % received polytherapy. Among unplanned pregnancies, 58.1 % didn't take AEDs, 28.0 % took monotherapy, and 12.8 % received polytherapy. The planned pregnancies had less generalized tonic-clonic seizures (P = 0.002) and higher proportion of being seizure-free (41.0 % vs. 22.8 %; P <0.001). All planned pregnancies took folic acid while 39.8 % of unplanned pregnancies never took it (P <0.001). The planned pregnancies had less rates of induced abortions (2.7 % vs. 13.5 %; P <0.001), preterm births (3.3 % vs. 20.4 %; P <0.001), and major congenital malformations (1.6 % vs. 7.5 %; P = 0.016). Pregnancy planning was independently associated with adverse fetal outcomes (adjusted OR, 0.14; 95 % CI, 0.08-0.27; P <0.001). CONCLUSION Planned pregnancy in WWE contributes to more optimized AED pattern, better seizure control, more appropriate folic acid supplementation, and less adverse fetal outcomes.

Abstract
AIM The goal of this retrospective study was to analyze the proportion of women with epilepsy who had received valproate (VPA) prescriptions in certain regions of Russia in 2018. METHODS This retrospective cross-sectional study was based on the IQVIA Russia longitudinal prescriptions (LRx) database and included all individuals with a documented epilepsy code (International Classification of Diseases, Tenth Revision [ICD-10]: G.40) from 13 regions in Russia who had received at least one prescription of an antiepileptic drug (AED). The prevalence of VPA prescriptions in female patients with epilepsy aged 16-45 years was analyzed by age group and epilepsy diagnosis code. A multivariate logistic regression model was used to study the association between predefined variables and the probability of having received a VPA prescription. RESULTS We found a total of 15,412 patients with epilepsy aged 16-45 who had received AED prescriptions in 2018 in the LRx database; 4488 (29.1%) of those patients were women. Of those, 64% had received at least one VPA prescription in 2018. The highest prevalence of VPA prescriptions was found in the age group 16-20 years (69%). This prevalence decreased with age. When compared with women aged 41-45 years, the 16-20-year-old age group was associated with a 1.6-fold increased probability of having receiving a VPA prescription (odds ratio [OR]: 1.60; p < 0.001), followed by the 21-25-year-old age group (OR: 1.46; p < 0.001). Nevertheless, the majority of women received VPA in low dosages (below 700 MG per day). CONCLUSIONS The prevalence of VPA prescriptions in women of childbearing age was quite high in Russia. The therapeutic doses were in line with international guidelines and had low teratogenic potential. Further research is needed to gain a better understanding of the reasons for prescribing VPA to women with epilepsy who are of childbearing age.
