epilepsy status in pregnancy

The management of women with epilepsy (WWE) presents many challenges for physicians. The primary goal during pregnancy is to achieve the best possible control of seizures with the least adverse effects associated with exposure to antiseizure medications (ASMs). Even though the guidelines for managing pregnant WWE are expanding, no definitive guidelines exist for the treatment of status epilepticus (SE). Additionally, much of our data comes from the effect of generalized tonic clonic seizures on the fetus...

OBJECTIVE: Antiseizure medication (ASM) use interacts with vitamin B status in nonpregnant epilepsy populations. We aimed to examine the association between ASM and vitamin B status in pregnant women with epilepsy. METHODS: We performed a cross-sectional study of pregnancies in women with epilepsy enrolled in the Norwegian Mother, Father and Child Cohort Study from 1999 to 2008. Data on ASM and vitamin supplement use were collected from questionnaires. We analyzed maternal plasma concentrations of ASM and metabolites of folate, including unmetabolized folic acid (UMFA), riboflavin (vitamin B2), pyridoxine (vitamin B6), and niacin (vitamin B3) during gestational weeks 17-19...

OBJECTIVES: The aim of our study is to present the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnancy and evaluate its impact on maternal and neonatal outcomes. METHODS: We retrospectively reviewed the medical records of all COVID-19 positive pregnant women who were admitted to "Alexandra" maternity hospital from March to December 2020 (n=40). The infection status was determined via real-time polymerase chain reaction (RT-PCR) of nasopharyngeal swab specimen...

Super-refractory status epilepticus is a rare medical and neurological emergency due to the high mortality and morbidity associated with this condition. Furthermore, there is very little data regarding its incidence, etiology, and management in the pregnant population with super-refractory status epilepticus. The treatment of super-refractory status epilepticus during pregnancy is specifically a major challenge as there are limited available therapeutic options due to the well-established teratogenicity of most antiepileptic drugs and the unknown safety profile of some of the anesthetics commonly used for seizure control...

Cortical dysplasia (CD) is a common cause of drug-resistant epilepsy. Increasing studies have implicated innate immunity in CD with epilepsy. However, it is unclear whether innate immune factors induce epileptogenic CD. Here, we injected recombinant human high mobility group box 1 (rHMGB1) into embryonic rat ventricles to determine whether rHMGB1 can induce epileptogenic CD with pathophysiological characteristics similar to those of human CD. Compared with controls and 0.1 μg rHMGB1-treated rats, the cortical organization was severely disrupted in the 0...

BACKGROUND: Vitamin B12 is an essential micronutrient for neurological function, as it leads to the regeneration of methionine from homocysteine, which is precursor of biologically active molecule S-Adenosyl Methionine (SAM). Pregnancy is a state of increased demand and delayed postpartum repletion of nutrients may predispose women to depression. METHODS: We included women who visited the hospital at 6-weeks postpartum for a regular checkup. Inclusion criteria were age (18-50 years), and willingness to donate venous sample for analysis...

BACKGROUND: We aim to describe the long term follow-up of a cohort of children exposed in utero to the Zika virus. METHODS: Descriptive study of a cohort of microcephalic children due to Zika virus. Logistic regression was used to evaluate variables associated with worse prognosis epilepsy. RESULTS: We followed 28 children (15 females), with a median follow-up of 24 months (IQR = 12-28). During the follow-up, 1 infant died. The median head circumference at birth was 29 cm (IQR = 27-31)...

OBJECTIVE: To evaluate the clinical characteristics of maternal deaths with epilepsy in Turkey. STUDY DESIGN: This epidemiological population-based study was conducted on all consecutive early maternal deaths with epilepsy in Turkey from 2012 to 2019. Maternal deaths accompanied by epilepsy as a comorbidity (n = 13) were evaluated separately. Epilepsy related maternal deaths were divided into two groups: 1) status epilepticus (n = 19) and 2) Sudden unexpected death in epilepsy (n = 19)...

INTRODUCTION: The association of family cases of epilepsy and intellectual disability in women was reported in 1971. In 2008, the role of pathogenic variants of the PCDH19 gene in some families were identified. The disease presents with febrile seizure clusters, intellectual disability, and autistic features. Most cases are due to de novo variants, however, there are some inherited cases, with an atypical way of X-linked transmission. OBJECTIVE: To report the case of a patient with epilepsy carrier of a pathogenic variant of the PCDH19 gene, reviewing the natural history of this condition and the available evidence for its management...

Objective: To investigate the clinical characteristics, treatment and prognosis of QARS1 gene related glutaminyl-tRNA synthetase deficiency. Methods: To summarize and analyze the clinical manifestations, imaging, laboratory examination, genetic variant characteristics and treatment of three patients from the Fujian Medical University Affiliated Union Hospital, the 900th Hospital of People's Liberation Army, the First Medical Center of People's Liberation Army General Hsopital carrying compound heterozygous variations in QARS1 gene with a long-term follow-up in China...

Children with Congenital Zika Syndrome and microcephaly are at high risk for epilepsy; however, the risk is unclear in normocephalic children with prenatal Zika virus (ZIKV) exposure [Exposed Children (EC)]. In this prospective cohort study, we performed epilepsy screening in normocephalic EC alongside a parallel group of normocephalic unexposed children [Unexposed Children (UC)]. We compared the incidence rate of epilepsy among EC and UC at one year of life to global incidence rates. Pregnant women were recruited from public health centers during the ZIKV outbreak in Grenada, West Indies and assessed for prior ZIKV infection using a plasmonic-gold platform that measures IgG antibodies in serum...

BACKGROUND: Since the introduction of highly active antiretroviral therapy (HAART), acquired immune deficiency syndrome (AIDS) related mortality has markedly declined. As HAART is becoming increasingly available, the infection with human immunodeficiency virus (HIV+) in sub-Saharan Africa (SSA) is becoming a chronic condition. While pregnancy in HIV+ women in SSA has always been considered a challenging event for the mother and the fetus, for pregnant HIV+ women also diagnosed with epilepsy (WWE), there are additional risks as HIV increases the odds of developing seizures due to the vulnerability of the central nervous system to other infections, immune dysfunction, and overall metabolic disturbances...

BACKGROUND: Brazil experienced a disproportionately higher rate of microcephaly cases in November 2015 with evidence of a causal link with Zika virus (ZIKV) infections during pregnancy. Epilepsy is a major neurological feature seen as part of congenital Zika virus syndrome (CZVS). Different seizure types and electroencephalographic (EEG) abnormalities have been described in association with this syndrome. However, clinical and neurophysiological features of epilepsy seen in children with CZVS are not fully understood...

Laboratory investigations, whilst not essential to the diagnosis of seizures or of epilepsy, can be fundamental to determining the cause and guiding management. Over 50% of first seizures have an acute symptomatic cause, including a range of metabolic, toxic or infectious cause. The same triggers can precipitate status epilepticus, either de novo or as part of a deterioration in control in individuals with established epilepsy. Some, such as hypoglycaemia or severe hyponatraemia, can be fatal without prompt identification and treatment...

BACKGROUND: Pregnancy in women with epilepsy (WWE) is known to have a higher risk for fetal development complications, which may include congenital malformations. Unfortunately, information pertaining to pregnancy in WWE is difficult to obtain because there are considerable ethical issues preventing these studies from being conducted on pregnant women. Therefore, this study investigated the pregnancies of Korean WWE in a tertiary epilepsy center to observe data resulting from the outcome of the pregnancies...

OBJECTIVE: Epilepsy is a nervous system abnormality that may be caused by unknown exposures during fetal development. Studies have shown neuroprotective effects of early exposure to vitamin D in other neurological disorders, and seasonal variation in birth of children with epilepsy. We aimed to investigate if neonatal 25(OH)D3 was associated with risk of childhood epilepsy. METHODS: This case-cohort study compared neonatal 25(OH)D3 levels from children with epilepsy (n = 403) and a random selected cohort of controls (n = 1163), assessing the hazard of first epilepsy diagnosis between 1 and 4 years of age from a weighted Cox proportional hazard model...

The use of ketogenic diet therapies (KDT) in adults has expanded in the last two decades and has been accompanied by a surge of new retrospective as well as prospective studies evaluating its efficacy in adults with epilepsy. In this review article, we will highlight the recent clinical trials and advances in the use of the ketogenic diet therapy (KDT) in adult patients with epilepsy. We will analyze the responder rate in regard to the epilepsy syndrome (focal vs generalized) to identify adults who are optimal to consider for KDT...

Introduction : Antiepileptic drugs (AEDs) are the cornerstone of treatment of patients with epilepsy, and there are presently 27 licensed AEDs making AEDs among the most common medications for which therapeutic drug monitoring (TDM) is performed. The aim of this review is to provide an overview of the current evidence of the use and implementation of AED TDM in patients with epilepsy and other non-epilepsy conditions. Areas covered : The pharmacokinetic variability of AEDs is extensive, resulting in pronounced variability in serum concentrations between patients...

Drug counseling is important in women with epilepsy since data about the effects of maternal antiepileptics on the developing fetus are limited. Although pregnant patients on the most teratogenic drugs are treated in accordance to the European Medicines Agency guidelines, a large amount of them may be exposed to the teratogenic medications unintentionally. We performed a tertiary center observational study about medications of pregnant women who were consulted to Teratology Information Service (TIS) unit for evidence-based teratogenic risk analysis...

BACKGROUND: How to safely treat pregnant women with epilepsy is a question for which there are guidelines, but variations in practice exist. METHODS: To better characterize how clinicians address this difficult clinical question, we distributed an anonymous survey to neurology practitioners across subspecialties and different levels of training via the Neurology ® : Clinical Practice website. The survey was conducted from May 31 to December 3, 2017. We received responses from 642 participants representing 81 countries...
