The effectiveness of preconception counseling to reduce adverse pregnancy outcome in women with epilepsy: what's the evidence?

Counseling on the Need for Folic Acid in Adolescents With Epilepsy

Background and Objectives

Folic acid is an important supplement to take for women with epilepsy on antiseizure medications (ASMs). Determination of baseline counseling given to women with epilepsy and the association with folic acid being recommended were evaluated. Factors surrounding the association were reviewed.

Methods

An exploratory retrospective review of women with epilepsy seen at a large Midwestern pediatric institution was performed between January 2018 and January 2020.

Results

Patients who received preconception counseling were more likely to be given a recommendation to take folic acid. Patients on more than 1 ASM were likely to receive counseling. Patient age and race were associated with having folic acid recommended.

Discussion

Providing preconception counseling for women with epilepsy is associated with an increased recommendation and prescription of folic acid. Further evaluation into possible disparities to receiving a folic acid recommendation is needed.

Women with mental illness seeking conception counselling at a specialist perinatal psychiatry service in India

AIMS

To study the clinical and sociodemographic profile of women with mental illness seeking conception counselling at perinatal psychiatry service. To compare women seeking preconception counselling (PCC) to that of those who sought help after unplanned pregnancy with exposure (UPE) to psychotropics.

MATERIAL AND METHODS

Data was extracted from the clinical records of women between the year 2014-2017 who attended perinatal outpatient services. The details collected included sociodemographic details, illness details, contraception, infertility treatment and detailed treatment history.

RESULTS

Of the 766 women who consulted perinatal psychiatry services (2014-17), 179 (23.37%) had consulted for conception counselling. Out of that 104 (58.1%) sought PCC, and 75 (41.9%) had UPE to psychotropics. PCC was sought by women with higher education, those having a severe mental illness, and a longer duration of illness. Women with medical comorbidities and receiving infertility treatment also sought PCC. Also, women who had earlier undergone PCC been more likely to seek PCC for further pregnancies.

CONCLUSIONS

Women with mental illness should be counselled regarding planned pregnancies, contraception, and the impact of psychotropics on pregnancy and foetus. Also, liaison with other specialities like obstetricians, sonologist and paediatricians is essential.

Society for Maternal-Fetal Medicine Consult Series #55: Counseling women at increased risk of maternal morbidity and mortality

Women should be provided with evidence-based information when considering options for contraception and pregnancy management. When counseling about health conditions and available treatments, healthcare practitioners should employ strategies that encourage the incorporation of informed patient preferences into a shared decision-making process with the patient. To optimize the health of women at risk of experiencing adverse health outcomes during or after pregnancy, counseling should be a continuous process throughout the reproductive life course. The purpose of this Consult is to provide guidance for all healthcare practitioners about counseling reproductive-aged women who may be at high risk of experiencing maternal morbidity or mortality.

Knowledge of pregnancy and procreation in women with epilepsy of childbearing age: A 16-year comparative study in Poland

Studies across countries and time periods have demonstrated insufficient pregnancy-related knowledge in women with epilepsy (WWE) of childbearing age. To assess the current state of such knowledge as well as the relevant time-related changes over 16 years in Poland, we conducted a study of WWE using a questionnaire developed in 2003. The participants were 656 WWE of childbearing age who completed online and paper-based questionnaires. The results were compared with those obtained in 2003. Overall, pregnancy-related knowledge improved significantly over 16 years. This improved knowledge was most evident in preconception use of folic acid and breastfeeding. However, even now, less than 40% of WWE believe that breastfeeding is possible in most cases. In 2019, pregnancy-related knowledge was positively correlated with participants' educational level and hometown size and negatively correlated with the frequency of generalized tonic-clonic seizures. Women completing the online survey had better knowledge than those who completed the paper-based survey. Indications for cesarean section, the possibility of using oral contraception and breastfeeding are the areas where knowledge in WWE remains inadequate, necessitating targeted educational activities.

Systematic review and meta-analysis of the impact of preconception lifestyle interventions on fertility, obstetric, fetal, anthropometric and metabolic outcomes in men and women

STUDY QUESTION

What is the impact of preconception lifestyle interventions on live birth, birth weight and pregnancy rate?

SUMMARY ANSWER

Lifestyle interventions showed benefits for weight loss and increased natural pregnancy rate, but not for live birth or birth weight.

WHAT IS KNOWN ALREADY

Evidence on the practice and content of preconception counseling and interventions is variable and limited.

STUDY DESIGN, SIZE, DURATION

Systematic review and meta-analysis (MA). Main search terms were those related to preconception lifestyle. Database searched were Ovid MEDLINE(R), EBM Reviews, PsycINFO, EMBASE and CINAHL Plus. No language restriction was placed on the published articles. The final search was performed on 10 January 2017.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Participants were non-pregnant women of childbearing age intent on conceiving or their male partners. Exclusion criteria include participants with BMI < 18 kg/m2, animal trials, hereditary disorder in one or both partners and trials focusing solely on alcohol or smoking cessation/reduction, micronutrient supplementation, or diabetes control. Anthropometric, fertility, obstetric and fetal outcomes were assessed. Bias and quality assessments were performed.

MAIN RESULTS AND THE ROLE OF CHANCE

The search returned 1802 articles and eight studies were included for analysis. Populations targeted were primarily overweight or obese subfertile women seeking reproductive assistance, with few community-based studies and none including men. MA showed greater reduction in weight (n = 3, P < 0.00001, mean difference: -3.48 kg, 95% CI: -4.29, -2.67, I2 = 0%) and BMI (n = 2, P < 0.00001, mean difference: -1.40 kg/m2, 95% CI: -1.95, -0.84, I2 = 24%) with intervention. The only significant fertility outcome was an increased natural pregnancy rate (n = 2, P = 0.003, odds ratio: 1.87, CI: 1.24, 2.81, I2 = 0%). No differences were observed for ART adverse events, clinical pregnancy, pregnancy complications, delivery complications, live birth, premature birth, birth weight, neonatal mortality or anxiety. Risk of bias were high for three studies, moderate for three studies and low for two studies, Attrition bias was moderate or high in majority of studies.

LIMITATIONS, REASONS FOR CAUTION

Results were limited to subfertile or infertile women who were overweight or obese undergoing ART with no studies in men. The heterogeneous nature of the interventions in terms of duration and regimen means no conclusions could be made regarding the method or components of optimal lifestyle intervention. Attrition bias itself is an important factor that could affect efficacy of interventions.

WIDER IMPLICATIONS OF THE FINDINGS

Existing preconception lifestyle interventions primarily targeted overweight and obese subfertile women undergoing ART with a focus on weight loss. It is important to note that natural conception increased with lifestyle intervention. This emphasizes the need for further research exploring optimal components of preconception lifestyle interventions in the broader population and on the optimal nature, intensity and timing of interventions.

Preconception healthcare and congenital disorders: systematic review of the effectiveness of preconception care programs in the prevention of congenital disorders

Congenital disorders are a leading cause of global burden of disease; the birth prevalence remains constant at 6%. Initiating preconception care before pregnancy may be an effective strategy to reduce congenital disorders and improve the health of reproductive-age women. Our objectives are: (1) To identify components of preconception interventions, (2) to assess the effectiveness of preconception interventions in reducing the burden of congenital disorders, and (3) to prioritize these interventions. Medline and Science Direct search terms included: preconception, pre-pregnancy, childbearing, reproduction, care, intervention, primary care, healthcare, model, program, prevention, trial, efficacy, effectiveness, congenital disorders OR abnormalities. Inclusion criteria were: (1) English, (2) human subjects, (3) women of childbearing age, (4) 1980-current data, (5) all countries, (6) experimental studies, (7) systematic reviews or meta-analysis, (8) program reports/evaluations. Data was collected and abstracted by two independent reviewers. To prioritize preconception interventions likely to have the largest impact at a population level, a ranked scoring system was created incorporating the following: (1) quality of evidence supporting the intervention, (2) effect size of the intervention, and (3) global burden of the specific congenital disease. Preconception interventions include risk screening, education, motivational counseling, disease optimization and specialist referral. The most effective interventions, based on the strength of evidence, size of impact of intervention, and disease burden are: folic acid fortification/supplementation, diabetic control, smoking and alcohol interventions, HIV management, thrombophillia screening, obesity prevention and epilepsy management. Although multiple conditions require preconception attention, only nine interventions have evidence to support their effect on congenital disorders through a randomised control trial, systematic review or meta-analysis. There is a need for more high-level research in evaluating certain preconception interventions. These findings have significant implications on planning and implementation of preconception care.

Impact of the implementation of the AAN epilepsy quality measures on the medical records in a university hospital

Background

The American Academy of Neurology (AAN) suggested eight quality measures to be observed at every patient visit. The aim of this work is to compare the percentage of documentation of each measure before and after the implementation of a new worksheet in a third-level center.

Methods

Quasi-experimental study including medical records filled by medical school seniors and junior residents supervised by an epileptologist. The authors surveyed 80 consecutive charts of people with epilepsy who were seen in the outpatient clinic before and after the intervention. McNemar change test was used to compare the percentages of documentation of each quality measure–i.e., seizure type and frequency, etiology, EEG, MRI/CT head scans, AED side effects, surgical therapy referral, safety counseling, preconception counseling–and physical exam. Each quality measure was considered to be fulfilled only if it was assessed and properly recorded.

Results

Mean age was 35(±13) years, 55% women, mean epilepsy onset at age 18(±15), 82% presented with partial-onset seizures. The reporting rate improved for all quality measures (previous vs new), reaching statistical significance for: seizure type 80vs94% (p < 0.05), AED side effects 8vs24%, etiology 66vs88% (p < 0.01), safety counseling 5vs64%, preconception counseling 4vs20%, and physical exam 63vs94% (p < 0.001).

Conclusion

A quality-oriented epilepsy worksheet led to a better practice standardization and documentation of AAN standards for diagnostic and counseling purposes. Further evaluations should be undertaken to assess the impact on medical education and patient care.

Pregnancy-related knowledge, risk perception, and reproductive decision making of women with epilepsy in Korea

PURPOSE

To determine the influence of pregnancy-related knowledge and the risk perception on reproductive decision making in women with epilepsy.

METHODS

We enrolled women with epilepsy, who were of reproductive age and were considering having children in the future. A questionnaire was used to assess the level of pregnancy-related knowledge, perception of the offspring's risk for developing epilepsy or for having a congenial anomaly, and discussion with a physician concerning pregnancy-related issues. We evaluated the following outcome variables: (1) the decision to discontinue anti-epileptic drug (AED) during a future pregnancy regardless of the medical indication; and (2) the decision to have fewer children because of epilepsy.

RESULTS

We enrolled a total of 186 women with epilepsy. (1) Fifty-eight percent of the women were considering discontinuing AED during a future pregnancy regardless of the medical indication, and 25% of the women decided to have fewer children because of epilepsy. (2) The decision to discontinue AED during a future pregnancy was associated with low-level pregnancy-related knowledge. (3) The decision to have fewer children because of epilepsy was associated with an exaggerated perception of the offspring's risk for developing epilepsy. (4) The women who had ever discussed pregnancy-related issues with their physician were less likely to decide to discontinue AED during a future pregnancy; however, a discussion on this issue had no impact on their decision to have fewer children because of epilepsy.

CONCLUSION

More than 50% of the women would decide to discontinue AED during a future pregnancy, and 25% of the women stated that they would have fewer children because of epilepsy. These data highlight the importance of education on pregnancy-related issues and genetic risk counseling.

Seizures and intracranial hemorrhage

Seizures and intracranial hemorrhage are possible medical diseases that any obstetrician may encounter. This article reviews the cause, treatment, and medical management in pregnancy for seizures and intracranial hemorrhage, and how the two can overlap into preeclampsia or eclampsia. This article also highlights some challenging management issues from the obstetrician's perspective.

Neurologists' and neurology residents' knowledge of issues related to pregnancy for women with epilepsy

We aimed to assess physician knowledge for 2009 guidelines established by the American Academy of Neurology and American Epilepsy Society regarding issues related to pregnancy for women with epilepsy. A questionnaire was developed and distributed to all neurologists and neurology residents practicing in a large Canadian health region serving a population of 1.4 million. Descriptive statistics were obtained and percentage of correct responses was calculated. Forty-five physicians completed the survey (response rate = 83.3%), with a median correct score of 50%. Residents were more likely (93.3%) to state that this information was important to their practice than staff physicians (40.0%). Overall knowledge of outcomes associated with specific AEDs was poor; less than half of the physicians correctly indicated which AEDs were associated with adverse outcomes for the majority of drug-related questions. We recommend multifaceted, interactive implementation strategies for increasing knowledge of guideline contents.

Does folic acid use decrease the risk for spina bifida after in utero exposure to valproic acid?

PURPOSE

Women with child wish are advised to take folic acid supplements to reduce the risk for spina bifida. However, there is less evidence for this protective effect in women using valproic acid (VPA). We investigated the effect of folic acid in women exposed to VPA in the first trimester of pregnancy.

METHODS

A case-control study was performed with data from a population-based registry of congenital malformations. Our cases were spina bifida registrations and all other malformed registrations (excluding folic acid sensitive malformations) were used as controls.

RESULTS

The ORs for the effect of correct folic acid use were calculated among antiepileptic drug (AED) unexposed pregnancies 0.5 [95%CI: 0.3-0.7] and among VPA exposed pregnancies 1.0 [95%CI: 0.1-7.6].

DISCUSSION

Due to power-reasons, we cannot conclude that folic acid has no effect on the risk for spina bifida among VPA exposed pregnancies. Although for AED unexposed pregnancies we found a decreased risk. Results from (animal) studies support a biologically plausible association between VPA, folic acid and spina bifida. While folic acid might not be able to reduce the risk for lower spina bifida lesions caused by VPA, the use of folic acid might be important to reduce the risk for higher, folic acid sensitive spina bifida lesions. Further research is needed to get more insight in the most effective form and dose of FA in women that use VPA to reduce the risk for (higher forms of) spina bifida.
