Levetiracetam use during pregnancy in women with epilepsy: Preliminary observations from a tertiary care center in Northern India

Antiseizure medication use during pregnancy and neonatal growth outcomes: A systematic review and meta-analysis

AIMS

We aimed to systematically synthesize the current published literature on neonatal growth outcomes associated with antiseizure medication (ASM) use during pregnancy.

METHODS

We searched seven databases, from inception to 23 March 2022. We investigated small for gestational age (SGA) and low birth weight (LBW) as primary outcomes and birth weight, birth height, cephalization index and head circumference as secondary outcomes. The primary analysis included pregnant people exposed to any ASM compared with unexposed pregnant people. Subgroup analysis included ASM class analysis, within epilepsy group analysis and polytherapy compared to monotherapy.

RESULTS

We screened 15 720 citations and included 65 studies in the review. Exposed pregnant people had a significantly increased risk of SGA relative risk (RR) 1.33 (95% CI 1.18 to 1.50, I2 74%), LBW RR 1.54 (95% CI 1.33 to 1.77, I2 67%), and decreased birth weight with a mean difference (MD) of -118.87 (95% CI -161.03 to -76.71, I2 42%) g. A non-significant risk change in birth height and head circumference was observed. In subgroup analysis, ASM polytherapy, within epilepsy and ASM class analysis were also associated with an increased risk of SGA and LBW.

CONCLUSIONS

This meta-analysis demonstrates that pregnant people exposed to ASMs have a significantly increased risk of adverse fetal growth outcomes including SGA and LBW and decreased birth weight compared to unexposed pregnant people. Polytherapy was associated with higher risks compared to monotherapy. Additional studies are warranted on specific ASM risks.

Real-world safety of Levetiracetam: Mining and analysis of its adverse drug reactions based on FAERS database

INTRODUCTION

Levetiracetam is a relatively new and widely utilized anti-seizure medication; however, limited information is available regarding its adverse effects. This study aims to thoroughly investigate, evaluate, and present evidence on the safety profile of Levetiracetam, relying on data from the FDA Adverse Event Reporting System (FAERS) database to facilitate informed clinical decision-making.

METHODS

We employed various statistical measures, including Reporting Odds Ratio (ROR), Proportionate Reporting Ratio (PRR), and analysis by the Medicines and Healthcare Products Regulatory Agency (MHRA), to identify signals of adverse reactions associated with Levetiracetam. Positive signals consistent with Designated Medical Event (DME) were singled out for focused comparison and discussion.

RESULTS

The analysis of 26,182 adverse events linked to Levetiracetam as the primary suspected drug revealed 692 positive signals spanning 22 System Organ Classes (SOCs). Nervous system disorders were the most frequently reported, followed by psychiatric disorders, and general disorders and administration site conditions. 11 positive signals consistent with Preferred Terms (PTs) in DME were identified, predominantly concentrated in 6 SOCs. Among these, rhabdomyolysis, Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS) exhibited relatively large values of A, ROR, and Chi-squared. Additionally, PTs related to spontaneous abortion, drug interaction, urethral atresia, ventricular septal defect, and atrial septal defect showed significant strength.

CONCLUSIONS

The study indicates that Levetiracetam carries a potential risk of causing rhabdomyolysis, SJS, TEN, DRESS as well as spontaneous abortion. Signals related to drug interaction, urethral atresia, ventricular septal defect, and atrial septal defect warrant heightened attention in clinical use.

Levetiracetam Use During Pregnancy in Women With Active Epilepsy: A Hospital-Based, Retrospective Study from a Tertiary Care Hospital in North Eastern INDIA

Background and Purpose

Epilepsy during pregnancy is a therapeutic challenge. Since the 1990s, the number of licensed antiepileptic drugs has substantially increased, but safety data on managing epilepsy during conception, pregnancy, and postpartum period use of newer generation antiepileptic drugs and birth defects are limited. We analyzed efficacy and safety of levetiracetam during pregnancy in northeast Indian women with active epilepsy (WWAE) which is being presented here.

Design

Hospital based retrospective study.

Patients and Methods

A retrospective analysis was conducted based on clinical records at a tertiary care teaching hospital and referral center in Northeast India between June 2008 through June 2018 without any personal identifying information. The Obstetric data from pregnancy register was supplemented with detailed neurologic data retrieved from medical records.

Results

Of 103 women with active epilepsy, 47 (45.6%) received levetiracetam as monotherapy and 56 (54.4%) as polytherapy. During pregnancy, the seizure frequency was unchanged, or the change was better in the majority (61.1%) of the patients. With one twin pregnancy, there were 96 live births, 5 spontaneous abortions, 2 induced abortions, 1 stillbirth. However, the rate of small for gestational age was higher in WWAE, Apgar score at 5 min was lower in infants of WWAE, and the need for care in the neonatal ward and neonatal intensive care was higher. Seven of 103 exposed pregnancies had a major congenital malformation (6.79%), all 7 were exposed to other antiepileptic drugs. Generalized epilepsy accounted for 57.2%.

Conclusion

Pregnancy course is uncomplicated and neonatal outcome is good in the majority of women with active epilepsy with proper antenatal and neurologic care. Levetiracetam taken in monotherapy can be considered as safer alternative for women with epilepsy of childbearing age. Long-term follow-up of neuropsychological and cognitive development of the children of WWAE is still needed.

Maternal and neonatal outcomes among pregnant women with myasthenia gravis

Objectives Myasthenia gravis (MG) is an autoimmune disease affecting the neuromuscular junction marked by weakness and fatiguability of skeletal muscle. MG has an unpredictable course in pregnancy. Our purpose was to evaluate the effect of MG on maternal and neonatal outcomes. Methods Using the United States' Healthcare Cost and Utilization Project Nationwide Inpatient Sample from 2005 to 2015, we conducted a retrospective cohort study consisting of women who delivered during that period. Multivariate logistic regression models, adjusted for baseline maternal demographics and comorbidities, were used to compare maternal and neonatal outcomes among pregnancies in women with and without MG. Results During the study period, 974 deliveries were to women diagnosed with MG. Women with MG were more likely to be older, African American, obese, have Medicare insurance and be discharged from an urban teaching hospital. Women with MG were also more likely to have chronic hypertension, pre-gestational diabetes, hypothyroidism, and chronic steroid use. Women with MG were at greater risk for acute respiratory failure (OR 13.7, 95% CI 8.9-21.2) and increased length of hospital stay (OR 2.5, 95% CI 1.9-3.3). No significant difference was observed in the risk of preterm premature rupture of membranes, caesarean section or instrumental vaginal delivery. Neonates of women with MG were more likely to be premature (OR 1.4, 95% CI 1.2-1.8). Conclusions MG in pregnancy is a high-risk condition associated with greater risk of maternal respiratory failure and preterm birth. Management in a tertiary care center with obstetrical, neurological, anesthesia and neonatology collaboration is recommended.

Change in antiepileptic drug prescription patterns for pregnant women with epilepsy over the years: Impact on pregnancy and fetal outcomes

AIMS AND OBJECTIVES:

The objectives of the study were: (1) to determine if there is a change in pattern of antiepileptic drug (AED) prescription during pregnancy in women with epilepsy (WWE) attending a tertiary care institute in North India and (2) to determine if change in AED prescription pattern has resulted in improved fetal and maternal outcomes in WWE.

PATIENTS AND METHODS:

The current study was a retrospective analysis of records of WWE attending a medical and surgical disorder clinic of obstetrics and gynecology department of a tertiary care teaching hospital in North India. We retrospectively collected data of all the patients during the 5-year period from 2011 to 2015 (Group A) (n = 177) and compared it with our previously published data during the years 1987–1994 (Group B) (n = 219).

RESULTS:

There was significantly higher use of (i) levetiracetam (LEV) in Group A compared to Group B when women on monotherapy were compared (P<0.0001) and (ii) LEV (P<0.0001), clobazam (P<0.0001) and lamotrigine (P=0.0004) in Group A compared to Group B when women on polytherapy were compared. A significantly higher (P=0.02) number of women were using more than two antiepileptic drugs simultaneously in Group A compared to Group B. There was a significantly higher incidence (P = 0.001) of small for gestational age babies in Group A.

CONCLUSION:

Although there is an increase in the use of newer AEDs in WWE during pregnancy in North Indian population, it has not resulted in improved maternal and fetal outcomes. (2) to determine if change in AED prescription pattern has resulted in improved fetal and maternal outcomes in WWE.
