The longer term outcome of children born to mothers with epilepsy

OBJECTIVES: To determine the prevalence of cognitive delay and possible associated dysmorphic features in children exposed to antiepileptic drugs (AEDs) in utero. DESIGN: Retrospective study of children born to mothers with epilepsy. SETTING: Regional epilepsy clinics in Liverpool and Manchester, UK. PARTICIPANTS: Children aged between 6 months and 16 years born to mothers with epilepsy. MAIN OUTCOME MEASURES: Structured interviews, hospital records, clinical examination, and psychometric tests (Wechsler) were used to assess exposure and intelligence quotient (IQ). Blinded assessment of photographs was used to score children with characteristic dysmorphic features. RESULTS: A total of 249 children aged 6 and over were studied: 41 were exposed to sodium valproate, 52 to carbamazepine, 21 to phenytoin, 49 to polytherapy, and 80 were unexposed. Mean verbal IQ was significantly lower in the valproate group compared to unexposed and other monotherapy groups. Multiple regression analysis showed that both valproate exposure and frequent tonic-clonic seizures in pregnancy were significantly associated with a lower verbal IQ despite adjusting for other confounding factors. There was a significant negative correlation between dysmorphic features and verbal IQ in children exposed to valproate. CONCLUSIONS: This study identifies valproate as a drug carrying potential risks for developmental delay and cognitive impairment and is the first to suggest that frequent tonic-clonic seizures have a similar effect. Our results need to be interpreted with caution given their retrospective nature. Women with epilepsy need careful counselling about individual risk benefit of AED treatment before pregnancy.     

Children exposed to valproate in utero--population based evaluation of risks and confounding factors for long-term neurocognitive development

PURPOSE: To evaluate neurological and cognitive functioning of school-aged (> or =6 years) children exposed to valproate monotherapy in utero in a population based, evaluator-blinded, controlled study. METHODS: Studied children (N=39, aged 6.6-13.4 years) and their mothers were identified through a population based pregnancy registry. Mothers with carbamazepine monotherapy and mothers with epilepsy but without antiepileptic drug (AED) treatment during pregnancy and their age and gender matched children served as controls. Hospital records were reviewed and neurological examination (Touwens test), intelligent quotients (IQ) of mothers (WAIS), and children (WISC-III) and neuropsychological assessment of children (NEPSY) were performed evaluator-blinded. RESULTS: The prevalence of low intelligence (FIQ<80) was 19% (4/21) and the prevalence of exceptionally low intelligence (FIQ<70) 10% (2/21) in valproate (VPA) monotherapy exposed children. Children exposed to carbamazepine (CBZ) and children of women with epilepsy but without AED exposure during pregnancy had all at least low average intelligence. The mothers using valproate scored significantly lower (p<0.05) in FIQ, VIQ and PIQ tests and had also significantly lower (p=0.035) educational level. Altogether 21% (8/39) of the children had minor neurological dysfunctions. CONCLUSIONS: In a population based setting inheritance and cumulating environmental factors may partly explain the increased prevalence of neurocognitive symptoms in children exposed to valproate in utero although concern about the possible long-term effects of intrauterine valproate exposure does exist.     

The effects of valproate exposure in utero on behavior and the need for educational support in school-aged children

Children exposed to valproate monotherapy in utero were evaluated with respect to neurological functioning, behavior, and additional educational needs, and the results were compared with those for age- and gender-matched controls exposed to carbamazepine and children with no prenatal exposure to antiepileptic drugs. We identified from the community-based pregnancy registry of Kuopio University Hospital area (1989-2000) all first-born and school-aged children exposed to valproate (N=13). Neurological and neuropsychological assessments were made clinically, and behavioral problems were assessed with the Conners' Teacher Rating Scale (CTRS). Eight children (62%) exposed to valproate and two (15%) each in the carbamazepine-exposed and nonexposed groups (P=0.022) required educational support. Minor dysmorphic features were noted in eight children (62%) exposed to valproate and in three children (23%) each in the carbamazepine-exposed and nonexposed groups. On CTRS, children exposed to valproate received higher scores, indicating behavioral problems. In our small but population-based study, all children exposed to valproate had minor, and some of them major, cognitive or neurological problems. This difference is clearly observed when assessing each child individually, but the many confounding factors explaining at least part of this difference are difficult to control and avoid in clinical practice. Larger studies with a prospective design are needed to confirm these findings.     

Outcome of pregnancy in women attending an outpatient epilepsy clinic: adverse features associated with higher doses of sodium valproate

The risk of an adverse outcome to pregnancy is increased in women with epilepsy. This is partly attributable to antiepileptic drugs. Guidelines for the management of pregnancy in women with epilepsy generally advise against polytherapy but make no distinction between the risks of different drugs. Several recent studies have however shown greater risk of adverse outcome in offspring exposed to sodium valproate in utero, particularly at higher doses. The outcome of pregnancy was monitored to identify antiepileptic drug treatment associated with a poor outcome in a mainly prospective study of women attending an outpatient clinic. From January 1990 to December 1999 all 69 pregnancies in women referred to the clinic were monitored. Drug treatments and other risk factors were recorded. In each child dysmorphic features, developmental delay and structural anomalies were assessed and graded. Data were analysed for drug- and dosage-dependent differences in outcome. In each assessment area a positive association between adverse outcome and dose was found for sodium valproate but not for carbamazepine. Severe adverse outcomes were found only in children exposed to sodium valproate at maternal doses above 1000 mg per day.

Children exposed to valproate monotherapy in utero were evaluated with respect to neurological functioning, behavior, and additional educational needs, and the results were compared with those for age- and gender-matched controls exposed to carbamazepine and children with no prenatal exposure to antiepileptic drugs. We identified from the community-based pregnancy registry of Kuopio University Hospital area (1989–2000) all first-born and school-aged children exposed to valproate (N = 13). Neurological and neuropsychological assessments were made clinically, and behavioral problems were assessed with the Conners’ Teacher Rating Scale (CTRS). Eight children (62%) exposed to valproate and two (15%) each in the carbamazepine-exposed and nonexposed groups (P = 0.022) required educational support.

Additional educational needs in children born to mothers with epilepsy

OBJECTIVES: To examine the relative risks of additional educational needs (AENs) in children exposed to antiepileptic drug (AED) monotherapy and polytherapy regimes in utero. METHODS: A retrospective survey of women between the ages of 16 to 40 registered at the Mersey Regional Epilepsy Clinic, who received a postal questionnaire concerning their experience of pregnancy and the subsequent schooling of live-born children. RESULTS: 721 (57%) women of the 1267 approached returned an adequately completed questionnaire; 330 (46%) had given birth to at least one live-born child. Information was collected on 594 children, 400 of whom were of school age (4-18). 150 (37.5%) had been exposed to monotherapy in utero, 74 (18.5%) were exposed to polytherapy, and 176 were not exposed to any AEDs. The odds ratio of AENs for all children exposed to AEDs in utero compared with those unexposed was 1.49 (95% confidence interval (95% CI) 0.83 -2.67). Odds ratios for AENs for each therapy subgroup compared with those unexposed were also calculated for all children. Those exposed to valproate monotherapy had an odds ratio of 3.4 (95% CI 1.63-7.10) by contrast with an odds ratio of 0.26 (95% CI 0.06- 1.15) for carbamazepine. Polytherapy including valproate had similarly high odds ratios for AENs compared with those unexposed of 2.51 ( 95% CI 1.04-6.07) versus the odds ratio of 1.51 ( 95% CI 0.56-4.07) for polytherapy excluding valproate. CONCLUSIONS: Although the findings should be treated with caution, they suggest that monotherapy or polytherapy with valproate during pregnancy carries particular risks for the development of children exposed in utero.     

Fetal growth restriction and birth defects with newer and older antiepileptic drugs during pregnancy

The primary aim of this study was to assess the risks of fetal growth restriction and birth defects in children exposed prenatally to newer and older antiepileptic drugs, using an unselected epilepsy cohort. Deliveries recorded in the compulsory Medical Birth Registry of Norway 1999–2011 formed the study population. All 2,600 children exposed to antiepileptic drugs during pregnancy were compared to all 771,412 unexposed children born to women without epilepsy. Children of untreated mothers with epilepsy served as an internal control group. The main outcomes were small for gestational age birth weight and head circumference, and major congenital malformations. Children exposed to antiepileptic drugs had a moderate risk of growth restriction. Infants exposed to topiramate had a considerable risk of microcephaly (11.4 vs. 2.4 %; OR 4.8; CI 2.5–9.3) and small for gestational age birth weight (24.4 vs. 8.9 %; OR 3.1; 95 % CI 1.9–5.3). Carbamazepine, lamotrigine, levetiracetam, oxcarbazepine, gabapentin, and pregabalin had low malformation rates, whereas topiramate tended to have an elevated malformation rate. Valproate monotherapy was associated with a significant risk of birth defects (6.3 vs. 2.9 %; OR 2.5; CI 1.6–3.8), and specifically with septal heart defects and hypospadias. For mothers using valproate, the presence of major birth defect in one child was associated with a markedly increased risk for the siblings (42.9 vs. 6.7 %; OR 10.4; CI 2.3–46.7). Children of untreated mothers with epilepsy had malformation risk similar to the reference group. In conclusion, topiramate was associated with a substantial risk of fetal growth restriction, and possibly an increased malformation rate. Other newer-generation antiepileptic drugs had a low malformation rate. Valproate monotherapy had a significant malformation risk, especially in repeated pregnancies.     

Antiepileptic drugs and neurodevelopment

Clinical studies have documented the teratogenic potential of antiepileptic drugs (AEDs). More recent cohort studies have been trying to sort out which AEDs impose the highest risk of teratogenicity. Currently, there is evidence demonstrating an increased risk of major congenital malformations (MCMs) for valproate, phenobarbital, and polytherapy during pregnancy. Based on the current data from multiple studies, the risk for valproate is the highest. Additional studies are needed to fully delineate if differences exist for other AEDs, especially the newer AEDs. However, although MCMs are easy to recognize and have been shown to be more common after in utero exposure to AEDs, there are insufficient data regarding their long-term effects on cognition and behavior in exposed children. Although most children born to women with epilepsy are healthy, in recent years there has been increasing awareness of the long-term effects of in utero exposure to AEDs. Recent discovery of neuronal apoptosis following in utero AED exposure in animals during a period that corresponds to the third trimester and early infancy in humans raises further concerns. Prospective clinical studies seem necessary in order to better understand the long-term neurodevelopmental effects of in utero exposure to AEDs.     

The potential for QT prolongation by antiepileptic drugs in children

Cardiac arrhythmia may be one of the major causes of sudden unexpected death in children with epilepsy. We assessed drug-induced QT prolongation to establish whether the use of antiepileptic drugs contributes to sudden unexpected death. A total of 178 children with epilepsy (93 males and 85 females, with ages ranging from 1 month to 18.9 years; mean age 7.0 +/- 4.1 years) were involved in the study. The QT intervals were manually measured and corrected using Fridericia's formula (QTFc = QT/RR(1/3)). The mean corrected QT interval (QTc) of 152 children on antiepileptic drugs during the study period was 0.40 +/- 0.03 s, and for 26 age-matched, antiepileptic drug-free control patients it was 0.40 +/- 0.03 s. The mean QTc of the children with monotherapy was 0.40 +/- 0.03 s for the valproate group (n = 42), 0.39 +/- 0.02 s for the carbamazepine/oxcarbazepine group (n = 34), and 0.40 +/- 0.02 s for the topiramate group (n = 26), respectively. There was no statistically significant difference among the groups as assessed by analysis of variance. In addition, there was no significant difference between the monotherapy group (n = 109; 0.40 +/- 0.02 s) and the polytherapy group (n = 43; 0.39 +/- 0.03 s). Major antiepileptic drugs may not precipitate prolongation of the QT interval into sudden unexpected death in children with epilepsy, however further studies are required.     

Epilepsy therapy: issues for women and men

It has been suggested that polycystic ovary syndrome is a common finding in women treated with valproate. However, in a recent study this suggestion could not be confirmed. There is currently no clear evidence that valproate contributes to the development of the polycystic ovary syndrome. Focal epileptic discharges may have an impact on the hypothalamic-pituitary-ovarian or -testicular axis. In the case of successful epilepsy surgery the impact of epilepsy on endocrine functioning may cease. This may lead to a normalization of disturbed menstrual cycles in women, and leads to a post-surgical increase of serum androgens in men. Both findings are supplemented by the results of animal experiments. Children exposed to antiepileptic drugs during pregnancy show a normal psychomotor and cognitive development. However, newly developed as well as traditional antiepileptic drugs increase the risk that a child exposed to these drugs during pregnancy will develop a malformation.     

Malformation risks of antiepileptic drugs in pregnancy: a prospective study from the UK Epilepsy and Pregnancy Register

OBJECTIVE: To assess the relative risk of major congenital malformation (MCM) from in utero exposure to antiepileptic drug (AEDs). METHODS: Prospective data collected by the UK Epilepsy and Pregnancy Register were analysed. The presence of MCMs recorded within the first three months of life was the main outcome measure. RESULTS: Full outcome data were collected on 3607 cases. The overall MCM rate for all AED exposed cases was 4.2% (95% confidence interval (CI), 3.6% to 5.0%). The MCM rate was higher for polytherapy (6.0%) (n = 770) than for monotherapy (3.7%) (n = 2598) (crude odds ratio (OR) = 1.63 (p = 0.010), adjusted OR = 1.83 (p = 0.002)). The MCM rate for women with epilepsy who had not taken AEDs during pregnancy (n = 239) was 3.5% (1.8% to 6.8%). The MCM rate was greater for pregnancies exposed only to valproate (6.2% (95% CI, 4.6% to 8.2%) than only to carbamazepine (2.2% (1.4% to 3.4%) (OR = 2.78 (p<0.001); adjusted OR = 2.97 (p<0.001)). There were fewer MCMs for pregnancies exposed only to lamotrigine than only to valproate. A positive dose response for MCMs was found for lamotrigine (p = 0.006). Polytherapy combinations containing valproate carried a higher risk of MCM than combinations not containing valproate (OR = 2.49 (1.31 to 4.70)). CONCLUSIONS: Only 4.2% of live births to women with epilepsy had an MCM. The MCM rate for polytherapy exposure was greater than for monotherapy exposure. Polytherapy regimens containing valproate had significantly more MCMs than those not containing valproate. For monotherapy exposures, carbamazepine was associated with the lowest risk of MCM.     

School performance at age 16 in children exposed to antiepileptic drugs in utero--a population-based study

Purpose: In order to evaluate long‐term effects on neurodevelopment in children born to women with epilepsy during pregnancy we studied the children’s school grades at age 16. Methods: We used the Patient Register, the Medical Birth Register, and a local study at South Hospital, Stockholm, to identify women with epilepsy in Sweden who had given birth between 1973 and 1986. The Swedish School Mark Registry was used to obtain information about school grades from the last year of compulsory school, at age 16. Exposed children were compared to all other children born in Sweden between 1973 and 1986. Key Findings: Medical records were analyzed for 1,235 children. Six hundred forty‐one children had been exposed in utero to antiepileptic drugs (AEDs) in monotherapy, 429 in polytherapy, and 165 to no known AED. Children exposed to polytherapy had an increased risk of not receiving a final grade—odds ratio (OR) 2.99 [95% confidence interval (CI) 2.14–4.17]. Children exposed to monotherapy, mainly carbamazepine or phenytoin, did not have a significantly increased risk of not receiving a final grade—OR 1.19 (95% CI 0.79–1.80). Children born to women with epilepsy had a decreased chance of getting a “pass with excellence.” Significance: Exposure to several AEDs in utero may have negative effects on neurodevelopment, and polytherapy should, if possible, be avoided in pregnant women.     

Valproate-induced eosinophilia in children with epilepsy: role of interleukin-5

Interleukin-5 contributes both in eosinophilopoiesis and neural development. Serum interleukin-5 levels were measured with enzyme-linked immunosorbent assay technique in 68 children with epilepsy receiving sodium valproate monotherapy and compared with the levels of 60 healthy controls and 14 children with epilepsy receiving carbamazepine. Eosinophilia was observed in 35.3% of children receiving valproate. Interleukin-5 in valproate users was significantly higher compared with children receiving carbamazepine and controls. Valproate users who exhibited eosinophilia had higher interleukin-5 levels compared with those without eosinophilia. However, the interleukin-5 level was also elevated, although to a lesser degree, in children without eosinophilia. The majority of valproate responders had high interleukin-5 levels. A positive correlation between interleukin-5 levels and the eosinophil count was also noted. We postulate that valproate contributes to the pathogenesis of eosinophilia, probably inducing interleukin-5 production. The finding that serum interleukin-5 was significantly elevated in valproate responders and even in valproate users without eosinophilia suggests that the increase in interleukin-5 might represent one of valproate's antiepileptic mechanisms.

Motor and mental development of infants exposed to antiepileptic drugs in utero

We prospectively evaluated the mental (MeDQ) and motor (MoDQ) developmental quotients of 395 (67.5% of the eligible) infants of mothers with epilepsy (IME) (mean age: 15 months) enrolled in the Kerala Registry of Epilepsy and Pregnancy between 1998 and 2004. The same developmental pediatricians, blinded to antiepileptic drug (AED) exposure, evaluated the children using the Indian adaptation of the Bayley Scale of Infant Development: Their mean MeDQ was 89.1+/-29.9 and mean MoDQ was 90.7+/-26.9. The MeDQ and MoDQ were impaired (<84) for 150 (37.6%) and 133 (33.5%) IME, respectively. Maternal age, type of epilepsy, seizure frequency, or use of folic acid did not correlate with the mean MeDQ or MoDQ. Maternal education was significantly correlated with the MoDQ, but not with the MeDQ, of the infants. Infants not exposed to AEDs (n=32) had a higher MeDQ (mean: 92.3, 95% CI: 81.4-103.2) and MoDQ (mean 94.7; 95% CI 84.9-104.5) than those exposed to AEDs (MeDQ--mean: 88.6, 95% CI: 85.5-91.6; MoDQ--mean: 90.0, 95% CI: 87.3-92.8). Those exposed to polytherapy had significantly lower developmental quotients than those exposed to monotherapy. Cumulative AED scores during pregnancy had an inverse relationship with developmental quotients. On multiple regression analysis, polytherapy was a stronger predictor of lower developmental quotients than dosage. Compared with carbamazepine monotherapy, valproate monotherapy was associated with significantly lower MeDQ and MoDQ in IME (93.1 and 95 vs 86.9 and 86.1), but the differences between other AEDs were not significant for IME exposed to valproate monotherapy. A limitation of the study is that the influence of maternal intelligence on developmental quotients was not evaluated.     

Early effect of sodium valproate and carbamazepine monotherapy on homocysteine metabolism in children with epilepsy

Plasma total homocysteine (p-tHcy), serum folate (s-F), serum vitamin B-12 (s-B12) and plasma pyridoxal-5'-phosphate (p-PLP) were measured in epileptic children before and after a 20-week period of sodium valproate (group A, n=32) and carbamazepine (group B, n=20) monotherapy. P-tHcy significantly increased in both groups, s-F and s-B12 significantly increased in group A, while s-F and p-PLP significantly decreased in group B. Our study showed an early effect of antiepileptic drug treatment on homocysteine metabolism.     

An open, nonrandomized clinical comparative study evaluating the effect of epilepsy on learning

Children with epilepsy, as a group, have a greater risk for developing learning problems as comorbid disorders. It is unknown which factors contribute to the development of such learning problems; therefore, our current knowledge does not allow the prediction of educational delay in an individual child with epilepsy. This study aimed at excluding as many factors as possible that could interfere with the analysis of the impact of epilepsy on learning. From patients referred to us in 1997 (N = 123), children were included with mild global learning impairment, defined as educational delay between 6 months and 1 year and no other apparent reason for learning impairment except for epilepsy (ie, excluding children with dyslexia, attention-deficit hyperactivity disorder, or mental handicap). A total of 44 patients fulfilled this criterion: 31 also had epilepsy (experimental group); the remaining 13 patients with similar mild learning impairment but without epilepsy were used as controls. In the experimental group two subgroups were distinguished on the basis of onset of learning impairment: in group A (n = 17) the learning problems are not unexpected as they were preceded by mild developmental delay; in group B (n = 14) the problems are unexpected and had a sudden onset. The two experimental groups differed from the control group on a number of variables, such as gender and the incidence of perinatal complications. More differences have been found between the two experimental groups: group B is selected from a larger group: all children with mild global learning impairment with sudden onset. In this group considerably more children with epilepsy have been found compared to the children with developmental delay; moreover the epilepsy is more often characterized in these children as "unexpected," that is, there was no previous established diagnosis of epilepsy, the symptoms were mostly unclear and behavioral in make-up (attentional lapses, etc); the electroencephalogram plays a much greater role in the diagnosis in this group, especially in demonstrating seizures; finally, the children in this group more frequently have neuropsychologic impairment. Children with epilepsy can have mild global learning difficulties, especially in the period after the onset of seizures. This group can be divided in a group with "trait-dependent learning difficulties," that is learning difficulties based on developmental delay, and a group with "state-dependent learning difficulties." The focus in our study was on this latter group, consisting of children with sudden and unexpected decline of results in school. The crucial finding in this group is the relatively frequent demonstration of difficult-to-detect seizures, demonstrating that an uncontrolled epilepsy can cause a decline in school results even when the seizures are of short duration and have subtle symptoms.

Antiepileptic drugs in pregnancy: late effects on the children's cognitive abilities. Preliminary data.

The authors report preliminary data on cognitive development of 57 children, perspectively followed, who were exposed to antiepileptic drugs in utero for maternal epilepsy. Cognitive impairments are associated with other risk factors in 5 cases, so that a direct AEDs responsibility is not easy to prove.     

Epilepsy and pregnancy: What should the neurologists do?

Epilepsy is one of the most common chronic disorders affecting women of childbearing age. Unfortunately, many women with epilepsy (WWE) still report not receiving key information about pregnancy. They obviously need information about epilepsy and pregnancy prior to conception with a particular emphasis on effective birth control (i.e. contraception), necessity to plan pregnancy, antiepileptic drugs optimization, and folate supplementation. The risks associated with use of antiepileptic drugs during pregnancy have to be balanced against fetal and maternal risks associated with uncontrolled seizures. This report reviews evidence-based counseling and management strategies concerning maternal and fetal risks associated with seizures, teratogenic risks associated with antiepileptic drug exposure with a special emphasis on developmental and behavioural outcomes of children exposed to intra utero antiepileptic drugs.
