Understanding the information needs of women with epilepsy at different lifestages: results of the 'Ideal World' survey

Evaluation of social inclusion in Brazilian adult women with epilepsy: Perception of stigma and quality of life

Epilepsy is a chronic disease characterized by recurrent epileptic seizures that can affect the perception of stigma and compromise the quality of life of those living with it. In addition, sociodemographic factors such as employment and maintaining a job, education, and the autonomy to drive vehicles are often impaired.

OBJECTIVE

To assess the social inclusion of adult women with epilepsy in relation to the perception of stigma and quality of life, and the clinical aspects of the disease.

METHODOLOGY

Data from 70 adult Brazilian women with epilepsy regarding aspects related to their social inclusion were verified. Such data were linked to clinical aspects and scores from the questionnaires: Quality of Life in Epilepsy Inventory 31 (QOLIE-31) and the Epilepsy Stigma Scale (ESS), with a significance level of p < 0.05.

RESULTS

Average age of 45.5 years, 40 (57.1 %) women were divorced/single/widowed, 31 (44.3 %) women had less than 10 years of formal education, 32 (45.7 %) women had no income, and 57 (81.4 %) did not have a driver's license. The age at the time of the first seizure was 18 years, the seizures were focal in 46 (65.7 %) cases, and 26 (37.1 %) cases were seizure-free in the last year. A high number of women reported that the diagnosis of epilepsy negatively influenced aspects of autonomy such as the possession of a driver's license and going out alone. Longer duration of epilepsy was associated with lower education, not having children, and lower scores on the QOLIE-31. Higher scores on the QOLIE-31 were correlated with lower frequency of seizures and with the age at the time of the first seizure. Values in the dimension - energy and fatigue of the QOLIE-31 were significantly lower in the group with less independence compared to the other two groups with more independence, in latent class analyses (ANOVA, adjusted for age 42.1 ± 35.6 vs 57.2 ± 28.4 vs 73.9 ± 23.8, p = 0.0295).

DISCUSSION

Clinical aspects of epilepsy and having a partner, autonomy, and independence such as driving vehicles are factors that contribute to social inclusion and to the perception of a better quality of life for adult women with epilepsy.

CONCLUSION

It was observed that having a partner, autonomy, and independence such as driving vehicles are factors that contribute to social inclusion and to the perception of a better quality of life for adult women with epilepsy.

Female sex steroids and epilepsy: Part 1. A review of reciprocal changes in reproductive systems, cycles, and seizures

Seizures, antiseizure medications, and the reproductive systems are reciprocally entwined. In Section 2 of this review, we outline how seizures may affect the hypothalamic-pituitary-gonadal axis, thereby altering sex steroids, and changes in sex steroids across the menstrual cycle and changes in pharmacokinetics during pregnancy may alter seizure susceptibility. The literature indicates that females with epilepsy experience increased rates of menstrual disturbances and reproductive endocrine disorders. The latter include polycystic ovary syndrome, especially for females on valproate. Studies of fertility have yielded mixed results. We aim to summarize and attempt to detangle the existing knowledge on these reciprocal interactions. The menstrual cycle causes changes in seizure intensity and frequency for many females. When this occurs perimenstrually, during ovulation, or in association with an inadequate luteal phase, it is termed catamenial epilepsy. There is a clear biophysiological rationale for how the key female reproductive neurosteroids interact with the brain to alter the seizure threshold, and Section 3 outlines this important relationship. Critically, what remains unknown is the specific pathophysiology of catamenial epilepsy that describes why not all females are affected. There is a need for mechanism-focused investigations in humans to uncover the complexity of the relationship between reproductive hormones, menstrual cycles, and the brain.

Persistent knowledge gaps between 2005 and 2020 in women with epilepsy: Comparison of multicenter studies from Germany

OBJECTIVE

Epilepsy is a chronic condition that can affect patients of all ages. Women with epilepsy (WWE) require access to specific counseling and information regarding issues related to contraception, pregnancy, and hormonal effects on seizure control and bone mineral density. This study investigated the knowledge among WWE regarding their condition, and whether epilepsy-specific knowledge has improved over the last 15 years.

METHODS

A total of 280 WWE aged 18 to 82 years participated in this multicenter, questionnaire-based study. The study was conducted at four epilepsy centers in Germany, between October 2020 and December 2020. Sociodemographic and epilepsy-specific data for participating women were analyzed and compared with the results of a similar survey performed in 2003-2005 among 365 WWE in Germany.

RESULTS

The questionnaire-based survey revealed considerable knowledge deficits without significant improvements over the last 15 years, particularly among those with less education and with regards to information on the more pronounced effects of epilepsy in older WWE (>50 years), including interactions with menopause and osteoporosis. In WWE ≤29 years, a significant increase in the knowledge score was observed in 2020 compared with this age group in 2005 (mean 7.42 vs. 6.5, p = .036). Mothers frequently reported epilepsy-related concerns regarding childrearing, particularly of seizures scaring their child and the need to rely on other people.

CONCLUSION

WWE continue to demonstrate inadequate epilepsy-related knowledge. Despite increasing information availability and the aspiration toward better awareness among medical professionals, overall knowledge has not increased sufficiently compared with the levels observed in recent studies.

Gender differences in concerns about planning to have children and child-rearing among patients with epilepsy: A prospective, multicenter study with 477 patients from Germany

OBJECTIVE

To analyze the concerns and worries about planning to have children and being a parent as a person with epilepsy and investigate gender differences in these perceptions.

METHODS

The Epi2020 study was a large multicenter study focusing on different healthcare aspects of adult patients with epilepsy in Germany. In addition to basic clinical and demographic characteristics, patients were asked to answer a questionnaire regarding their plan to have children, if they had children, and concerns about their children's health. Data were analyzed to detect differences between men and women with epilepsy according to age group.

RESULTS

In total, 477 patients with epilepsy with a mean age of 40.5 years (SD = 15.5, range: 18-83 years) participated in this study; 280 (58.7%) were female and 197 (41.3%) were male. Both women and men frequently reported concerns and worries about having children: In the age group below 45 years of age, 72.5% of women and 58.2% of men described being worried to some extent that their children may also suffer from epilepsy (p = .006). Furthermore, 67.3% of women and 54.2% of men below the age of 45 years reported being worried that their children may be disabled (p = .003). Women were more likely to have family members who are reluctant to support their desire to have children (p = .048).

CONCLUSION

Women with epilepsy of childbearing age are significantly more likely to report major concerns that their children might be disabled or also have epilepsy than men with epilepsy and, therefore, express more concerns about choosing to have a child. However, men also report frequent concerns and worries, and this should be addressed not only on request but should be included in the provision of general information on epilepsy.

Women's Issues in Epilepsy

PURPOSE OF REVIEW

Issues pertaining to women with epilepsy have advanced with a better understanding of multidirectional influences among hormones, seizures, and antiseizure medications, as well as pregnancy-related concerns around fertility, seizure destabilization, and antiseizure medication-associated teratogenicity. This article highlights important developments in this field and reviews best practices in the management of women with epilepsy.

RECENT FINDINGS

Important external hormonal influences may impact women with epilepsy particularly in the context of gender-affirming medications, hormonal replacement therapy, and fertility therapies. Fertility for women with epilepsy is influenced by multiple variables; however, in the absence of preexisting fertility issues, epilepsy per se is not associated with significantly impaired fertility. Once women with epilepsy are pregnant, the majority have a stable course. Antiseizure medication use in pregnancy is associated with major congenital malformations 2 to 5 times that of the general population and is highest with high-dose (≥1500 mg or greater total daily) valproate. Carefully considered changes in drug choice and dose may mitigate these risks. Therapeutic drug monitoring plays an important role in pregnancy care, and under expert supervision, women with epilepsy in pregnancy have similar seizure risks as women with epilepsy who are not pregnant. As women with epilepsy age, bone health and menopause may further be impacted by seizures and antiseizure medications.

SUMMARY

The care of women with epilepsy is a multifaceted discipline that recognizes the life-long impact of sex and gender influences on epilepsy care.

The Efficacy of Assisted Reproduction in Women with a Wide Spectrum of Chronic Diseases - A Review

Assisted reproductive technology (ART) treatments in women with underlying chronic diseases have become increasingly frequent. The objective of this review is to provide an overview of the literature examining the chance of having a live born child after ART in women with chronic diseases, compared to other women receiving ART. We focused on some of the most prevalent chronic diseases in women during their reproductive years, ie ulcerative colitis, Crohn's disease, rheumatoid arthritis, multiple sclerosis, epilepsy, hyperthyroidism, hypothyroidism, and diabetes mellitus. Secondly, we studied the chance of successful implantation. The literature search was performed in the database Pubmed.gov. including all studies published before October 2020. Title and abstracts of 58 papers were reviewed, 37 papers were excluded and other 8 studies were excluded after full-text evaluation. Only 13 papers were eligible for review. Results indicate that women with ulcerative colitis, Crohn's disease, rheumatoid arthritis, hyperthyroidism, and diabetes mellitus type 2 might have problems with low implantation rate or early embryo development during ART. On the contrary, the few studies on women with hypothyroidism, diabetes mellitus type 1, and epilepsy suggest an equivalent chance of a live birth compared to other women undergoing ART. A possible explanation behind these differences could reside in the disease-specific dysregulation of the innate or adaptive immune system. To our knowledge, this is the first review on ART in women with chronic diseases, and it has disclosed that the evidence in this area is indeed sparse. We encourage others to examine live birth after ART in women with chronic diseases.

Reproductive decision-making in families containing multiple individuals with epilepsy

OBJECTIVE

This study evaluated factors influencing reproductive decision-making in families containing multiple individuals with epilepsy.

METHODS

One hundred forty-nine adults with epilepsy and 149 adult biological relatives without epilepsy from families containing multiple affected individuals completed a self-administered questionnaire. Participants answered questions regarding their belief in a genetic cause of epilepsy (genetic attribution) and estimated risk of epilepsy in offspring of an affected person. Participants rated factors for their influence on their reproductive plans, with responses ranging from "much more likely" to "much less likely" to want to have a child. Those with epilepsy were asked, "Do you think you would have wanted more (or any) children if you had not had epilepsy?"

RESULTS

Participants with epilepsy had fewer offspring than their unaffected relatives (mean = 1.2 vs. 1.9, p = .002), and this difference persisted among persons who had been married. Estimates of risk of epilepsy in offspring of an affected parent were higher among participants with epilepsy than among relatives without epilepsy (mean = 27.2 vs. 19.6, p = .002). Nineteen percent of participants with epilepsy responded that they would have wanted more children if they had not had epilepsy. Twenty-five percent of participants with epilepsy responded that "the chance of having a child with epilepsy" or "having epilepsy in your family" made them less likely to want to have a child. Having these genetic concerns was significantly associated with greater genetic attribution and estimated risk of epilepsy in offspring of an affected parent.

SIGNIFICANCE

People with epilepsy have fewer children than their biological relatives without epilepsy. Beliefs about genetic causes of epilepsy contribute to concerns and decisions to limit childbearing. These beliefs should be addressed in genetic counseling to ensure that true risks to offspring and reproductive options are well understood.

The efficacy of assisted reproductive treatment in women with epilepsy

RESEARCH QUESTION

The question of interest for this study was to examine the chance of a live birth following assisted reproductive technology (ART) treatment in women with epilepsy compared with women without epilepsy. In sub-analyses, the chance of biochemical and clinical pregnancies, and the impact of antiepileptic drugs (AED) treatment prior to embryo transfer, was analysed.

DESIGN

This register-based cohort study was based on the Danish ART register comprising all women who underwent embryo transfer during 2006 to 2017, which included 730 ART treatments in 264 women with a history of epilepsy, and 128,387 ART treatments in 42,938 women without epilepsy. Adjustments were made for comorbidity, women's age, calendar year, type of infertility treatment and cause of infertility. A possible impact of AED use at the time of embryo transfer was studied in a sub-analysis. The primary outcome was live birth within a period of 140-308 days after the date of embryo transfer.

RESULTS

The adjusted odds ratio for a live birth per embryo transfer in women with epilepsy, relative to women without epilepsy, was 1.06 (95% confidence interval [CI] 0.88-1.28). The adjusted odds ratio for a live birth among users of an AED was 1.22 (95% CI 0.77-1.92) relative to women who had stopped the use of AED prior to embryo transfer.

CONCLUSIONS

The chances of a live birth per embryo transfer were similar in women with and without epilepsy. These are novel and reassuring findings on the efficacy of infertility treatment in women with epilepsy.

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.

Treatment decisions in women of childbearing age on valproate

INTRODUCTION

There are little data on the understanding and participation of women of childbearing age in decisions about their choice of antiepileptic drugs (AEDs). Valproate carries a risk of major congenital malformations, developmental and behavioural delay. For some, valproate is the only medication to prevent potentially life-threatening seizures.

MATERIALS & METHODS

This was a cross-sectional study of two groups of women of childbearing age; 50 taking valproate and 50 controls. Each patient completed a patient questionnaire and structured telephone interview assessing understanding of the risks and benefits of AEDs in relation to pregnancy. Analysis used unpaired two-tailed t test and chi-squared test, with Bonferroni correction. Follow-up at 12 months showed that 8% of the women taking valproate had switched to other medication.

RESULTS

Hundred patients participated in the study, 89 on AEDs for epilepsy, 4 for migraine, and 7 for both. 55% of participants stated they were not involved in decision-making. More patients in the valproate group were informed about (64% vs 42%, P < .005), and expressed understanding of (64%vs 32%, P < .001), the risks involved with treatment. 59% of all patients wanted more information. The minority of women surveyed took folic acid (37%) or used contraceptives (29%). Valproate was used following failure of other AEDs to control seizures in 80%.

DISCUSSION

This in-depth survey suggests more information is needed for women taking AEDs, using a range of formats. Women taking valproate are better informed than those on levetiracetam or lamotrigine. Information provision on the use of folic acid and contraception needs improvement.

Fertility and Birth Outcomes in Women With Epilepsy Seeking Pregnancy

Importance

Prior studies report lower birth rates for women with epilepsy (WWE) but have been unable to differentiate between biological and social contributions. To our knowledge, we do not have data to inform WWE seeking pregnancy if their likelihood of achieving pregnancy is biologically reduced compared with their peers.

Objective

To determine if WWE without a prior diagnosis of infertility or related disorders are as likely to achieve pregnancy within 12 months as their peers without epilepsy.

Design, Setting, and Participants

The Women With Epilepsy: Pregnancy Outcomes and Deliveries study is an observational cohort study comparing fertility in WWE with fertility in control women (CW) without epilepsy. Participants were enrolled at 4 academic medical centers and observed up to 21 months from November 2010 to May 2015. Women seeking pregnancy aged 18 to 40 years were enrolled within 6 months of discontinuing contraception. Exclusion criteria included tobacco use and a prior diagnosis of infertility or disorders that lower fertility. Eighteen WWE and 47 CW declined the study, and 40 WWE and 170 CW did not meet study criteria. The Women With Epilepsy: Pregnancy Outcomes and Deliveries electronic diary app was used to capture data on medications, seizures, sexual activity, and menses. Data were analyzed from November 2015 to June 2017.

Main Outcomes and Measures

The primary outcome was proportion of women who achieved pregnancy within 12 months after enrollment. Secondary outcomes were time to pregnancy using a proportional hazard model, pregnancy outcomes, sexual activity, ovulatory rates, and analysis of epilepsy factors in WWE. All outcomes were planned prior to data collection except for time to pregnancy.

Results

Of the 197 women included in the study, 142 (72.1%) were white, and the mean (SD) age was 31.9 (3.5) years among the 89 WWE and 31.1 (4.2) among the 108 CW. Among 89 WWE, 54 (60.7%) achieved pregnancy vs 65 (60.2%) among 108 CW. Median time to pregnancy was no different between the groups after controlling for key covariates (WWE: median, 6.0 months; 95% CI, 3.8-10.1; CW: median, 9.0 months; 95% CI, 6.5-11.2; P = .30). Sexual activity and ovulatory rates were similar in WWE and CW. Forty-four of 54 pregnancies (81.5%) in WWE and 53 of 65 pregnancies (81.5%) in CW resulted in live births. No epilepsy factors were significant.

Conclusions and Relevance

Women with epilepsy seeking pregnancy without prior known infertility or related disorders have similar likelihood of achieving pregnancy, time to pregnancy, and live birth rates compared with their peers without epilepsy.

Collaboration of Care for Women with Epilepsy in their Reproductive Years

Over half a million women of childbearing age have epilepsy, many of which will require family planning care at some point in their reproductive years. Matters relating to contraception, pregnancy, fertility, and sexual functioning are all impacted to varying degrees by the use of antiepileptic drugs (AEDs) to treat epilepsy and require active management by a woman's neurologist. It is important that a woman's obstetrician/gynecologist (OBGYN) and internist are aware of the way in which their care may be related to her epilepsy care and how this can be successfully comanaged with her neurologist. This includes the impact AED therapies have on pregnancy, such as risk of teratogenicity, changes to AED clearance rates during pregnancy and postpartum, and risk of seizure worsening while pregnant; interactions of hormonal contraceptives and AEDs; side effects of AED treatment on hormonal systems and sexual functioning; and matters of fertility and infertility treatments. The current editorial discusses these relationships between AED choice, dose, and family planning matters for women with epilepsy in their childbearing years to support the collaboration of care between her neurologist, OBGYN, and internist.

The preconception care experiences of women with epilepsy on sodium valproate

PURPOSE

To understand the preconception experiences of women with epilepsy who have been taking the teratogenic drug valproate.

METHODS

Seven women were recruited, three from a preconception clinic and four from an antenatal clinic in a region of the UK. All had taken valproate preconceptionally. Three preconception clinic encounters were observed and audio-recorded. Interviews with all women were analysed using Interpretative Phenomenological Analysis (IPA).

RESULTS

Women experienced a "trajectory of balance". Women moved from "maintaining balance" by using valproate to control seizures, to a "shattering of harmony" at the prospect of changing medication and as a result of the physical and mental effects of changing medication, to "restoring balance" which could involve "a new self" due to dramatic changes. Women balanced their health needs with those of their baby, and took responsibility for medication decision-making. They found it difficult to see "who is looking after me" in the healthcare system, either to access preconception care, or to support them through the stress of changing medication. Their journey ended with coming to terms with a variety of experiences: choosing not to have a baby due to unsuccessful change from valproate, recognising that a child from a previous pregnancy had been harmed by valproate or that the current pregnancy might be at risk, or successful medication change in preparation for pregnancy.

CONCLUSION

A clear and adequately funded preconception care pathway is needed from epilepsy diagnosis, including support for stress. Understanding what influences maternalisation may help understand uptake of preconception care.

Women with epilepsy in childbearing age: Pregnancy-related knowledge, information sources, and antiepileptic drugs

Pregnancy-related issues in epilepsy (PRIE) are essential for management of epilepsy in women. We conducted a study among women with epilepsy (WWE) aged 15-45years about their knowledge, sources, and needs for information regarding PRIE, which included their current antiepileptic drugs (AEDs) usage. Women with epilepsy, visitors of Croatian Association for Epilepsy webpage, were offered an online questionnaire, and 200 responses were analyzed. The mean number of correct answers about PRIE was 3.5 out of 5. Main predictors of knowledge on PRIE were a prior consultation with a neurologist and higher usage of books/brochures. A prior neurologist consultation on PRIE was stated by 45% of subjects. As the preferred future mode of being informed on PRIE, majority of women (61%) chooses their neurologist, 22% written materials distributed by a neurologist, and only 13% Internet. Levetiracetam was the most commonly used AED (34.5%). Valproate was used by 26%, and of those 59% stated no previous consultation on PRIE with their neurologist. In summary, we believe our study shows that knowledge of PRIE among WWE in their childbearing age is unsatisfactory, as are the neurologist consultation rates about PRIE. Our results demonstrate that, despite modern technologies, educational activities should be based on neurologist consultations and providing the patients with appropriate written materials. This is especially true for the relatively large proportion of women still taking valproate.

Pregnancy-related knowledge of women with epilepsy - An internet-based survey in German-speaking countries

There are several issues, which have to be acknowledged, when treating women with epilepsy (WWE). The need for counseling WWE in Germany with epilepsy on pregnancy-related matters was stressed in several papers and medical guidelines. Physicians treating WWE in Germany therefore should be aware of the information needs of their patients. We aimed to determine the level of pregnancy-related knowledge of WWE and their informational needs concerning pregnancy and childbirth issues in German-speaking countries by an internet-based survey. The questionnaire consisted of 18 questions addressing the characteristics of the epilepsy syndromes, the patients' experience with pregnancy, and the sources of their pregnancy-related knowledge. Another 20 items addressed the level of pregnancy-related knowledge. One hundred ninety-two women (179 patients, 13 relatives; age: 30.5±10.8years) participated. Most of the women got information and advice on the treatment of epilepsy from a neurologist (81%). Most of the women had obtained information concerning driving license (72%) followed by information about pregnancy and delivery (60%). The women, who remembered being counseled about pregnancy-related matters gave more correct answers to the pregnancy-related questions than the others (51±17% vs. 38±24%, p<0.011). Thirty-eight percent of WWE taking enzyme inducing antiepileptic drugs (AEDs) were unaware of the interaction with oral contraception. Forty-one percent of WWE taking valproate were unaware of its high teratogenicity, and 89% of WWE had not been counseled about potentially reduced bone mineral density. Forty-six percent of participants did not believe that the majority of WWE have healthy children. The findings of this survey reveal considerable information needs of WWE concerning pregnancy-related matters in German-speaking countries.

Menstrual disorders and their determinants among women with epilepsy

INTRODUCTION

The purpose of the present study was to assess the prevalence and determinants of menstrual cycle disorders among women with epilepsy.

MATERIALS AND METHODS

The study included consecutive women with epilepsy who visited a university epilepsy clinic. A number of variables, including demographics, characteristics of epilepsy and its treatment, and data related to reproductive health (regularity of menstrual cycle, number of pregnancies and childbirths), were collected from medical records, seizure diaries, and a dedicated questionnaire.

RESULTS

The study involved 271 women with epilepsy. Focal epilepsy was diagnosed in 182 (67.2%) patients; 108 (39.8%) women had rare seizures (<1 per year), and 164 patients (60.5%) were on monotherapy. Menstrual abnormalities were found in 78 patients (28.8%). Independent variables associated with irregular cycle included younger age at onset of epilepsy (OR=0.95 per 1-year increase; P=0.008), current use of clonazepam (OR=5.36; P=0.010), and chronic use of medication(s) other than antiepileptic drug(s) (AEDs; OR=2.48; P=0.003). Childbirth rate was low in our cohort (0.50 per patient); independent predictors of being childless in studied patients included younger age, presence of menstrual disorders, and greater number of currently used AEDs.

CONCLUSION

Menstrual disturbances were present in 28.8% of studied women with epilepsy. Increased prevalence of menstrual abnormalities was associated with epilepsy itself (younger age at onset of epilepsy) and its treatment (ongoing use of clonazepam), as well as with chronic use of medications other than AEDs.

Which information on women's issues in epilepsy does a community pharmacist need to know? A Delphi consensus study

OBJECTIVE

The aim of this study was to develop and achieve consensus on a core list of important knowledge items that community pharmacists should know on women's issues in epilepsy.

METHODS

This was a consensual study using a modified Delphi technique. Knowledge items were collected from the literature and from nine key contacts who were interviewed on their views on what information community pharmacists should have on women's issues in epilepsy. More knowledge items were suggested by five researchers with interest in women's issues who were contacted to rate and comment on the knowledge items collected. Two iterative Delphi rounds were conducted among a panel of pharmacists (n=30) to achieve consensus on the knowledge items to be included in the core list. Ten panelists ranked the knowledge items by their importance using the Analytical Hierarchy Process (AHP).

RESULTS

Consensus was achieved to include 68 knowledge under 13 categories in the final core list. Items ranked by their importance were related to the following: teratogenicity (10.3%), effect of pregnancy on epilepsy (7.4%), preconception counseling (10.3%), bone health (5.9%), catamenial epilepsy (7.4%), menopause and hormonal replacement therapy (2.9%), contraception (14.7%), menstrual disorders and infertility (8.8%), eclampsia (2.9%), breastfeeding (4.4%), folic acid and vitamin K (5.9%), counseling on general issues (14.7%), and sexuality (4.4%).

CONCLUSION

Using consensual knowledge lists might promote congruence in educating and/or training community pharmacists on women's issues in epilepsy. Future studies are needed to investigate if such lists can improve health services provided to women with epilepsy (WWE).

Which outcomes should we measure in adult epilepsy trials? The views of people with epilepsy and informal carers

OBJECTIVE

So that informed treatment decisions can be made, clinical trials need to evaluate treatments against domains that are important to people with epilepsy (PWE), their carers, and clinicians. Health professionals have identified domains of importance to them via the International League Against Epilepsy's Commission on Outcome Measurement (COME). However, patients and carers have not been systematically asked.

METHODS

Via the membership of the British Epilepsy Association, we recruited and surveyed 352 PWE and 263 of their informal carers. They were presented with 10 outcome domains (including the 5 identified by COME) and asked to rate their importance using a 9-point Likert scale. They were also asked to identify any additional domains of importance.

RESULTS

The patients' mean age was 49years, the median number of years since diagnosis was 20, and 65% had experienced seizures in the prior 12months. Most carers were the spouse or parent. Patients' and carers' mean ratings indicated that their outcome priorities were similar, as were those of patients who had and had not experienced recent seizures. There was consensus among patients that 6 domains were of critical importance. These included the 5 identified by COME (namely, and in order of importance, the effects of the treatment on "Seizure severity", "Seizure frequency", "Quality of life", "Cognitive function", and "Adverse events"), as well as one additional domain ("Independence/need for support"). There was consensus among carers that the 5 COME domains were also critically important. They, however, identified 3 further domains as critically important. These were the effects of the treatment on patient "Depression", "Anxiety", and "Independence/need for support".

CONCLUSIONS

Our study found some overlap between the priorities of PWE, carers, and health professionals. They, however, highlight additional areas of importance to patients and carers. Our results could inform a core outcome set for epilepsy that represents the domains that should be reported as a minimum by all trials. This could promote trials which produce meaningful results and consistency in measurement and reporting.

Contraception for women with epilepsy: counseling, choices, and concerns

Approximately 50% of all pregnancies in women with epilepsy (WWE) occur unplanned. This is worrying, given the increased occurrence of obstetrical complications in WWE, including the risk of seizures and their possible consequences for both the mother and the unborn child. Hormonal contraception is usually regarded as highly effective, but it is subject to numerous bidirectional drug interactions with several antiepileptic drugs. These interactions may lead to loss of seizure control or contraceptive failure. Further concerns are loss of bone mineral density and increased seizure activity due to hormonal effects. Many physicians lack sufficient knowledge regarding these issues, and most WWE have never received adequate counseling. Moreover, several studies show that a large proportion of WWE do not take their medicines regularly. This article reviews all of these issues and offers practical recommendations for the management of contraception in WWE.

Clinical utility of the Metacognitions Questionnaire 30 in people with epilepsy

OBJECTIVE

The Metacognitions Questionnaire 30 (MCQ-30) has been widely used to assess metacognitive beliefs and processes linked to emotional disorders. The aim of the present study was to test the utility of the MCQ-30 in assessing metacognitions in people with epilepsy.

METHODS

Three hundred forty-nine people with epilepsy completed the MCQ-30 and self-report measures of anxiety and depression at two time points, 12 months apart. Factor analyses and structural equation modeling were used to test the factor structure, internal consistency, and convergent validity of the MCQ-30.

RESULTS

Confirmatory and exploratory factor analyses supported the original five-factor structure and demonstrated that each factor had good to excellent levels of internal consistency.

CONCLUSION

The MCQ-30 is a robust measure of metacognitive beliefs and processes and has clinical utility in PWE.

Teratogenic medications and concurrent contraceptive use in women of childbearing ability with epilepsy

BACKGROUND

Many antiepileptic drugs (AEDs) have the potential to cause teratogenicity. We evaluated eight antiepileptic drugs (AEDs) classified as Federal Drug Administration (FDA) pregnancy category D, X, or N designations and having documented teratogenic effects. These include carbamazepine, ethosuximide, fosphenytoin, phenobarbital, phenytoin, primidone, topiramate, and valproate. Women with epilepsy (WWE) may need one or more of these AEDs for seizure control but may be unaware of the potential teratogenicity associated with their use. In utero exposure to AEDs increases the risks for both congenital malformations and other teratogenic defects. Given that approximately 50% of pregnancies are unintended, it is likely that women with epilepsy taking these medications could unknowingly put a growing fetus at risk. For women using contraception while taking these medications, many choose combined hormonal contraceptives (CHCs). Drug-drug interactions exist between AEDs and CHCs that may decrease contraceptive efficacy. The aim of this study was to evaluate prescribing patterns for potentially teratogenic AEDs and contraceptive use in WWE of childbearing ability, including those with potential drug-drug interactions. This study also determined the number of WWE of childbearing ability prescribed potentially teratogenic AEDs and documentation of a pregnancy or contraception plan.

METHODS

This was a retrospective, observational study of WWE age 15-44 years, of childbearing ability, prescribed an AED from July 1, 2011 to June 30, 2012, and who had an appointment at the University of Colorado Hospital Outpatient Neurology Clinic (Anschutz Medical Campus).

RESULTS

One hundred fifteen women with an average age of 30.7 years and various types of seizures were evaluated. The majority of patients were prescribed topiramate (34/115, 30%) or carbamazepine (27/115, 23%). Of the women, 30/115 (26%) had a documented contraception method when taking a potentially teratogenic AED. Of these women prescribed contraception, most (18/30, 60%) used an oral combined hormonal contraceptive or progestin-only pill, a majority of which had a potential for a drug-drug interaction with their AEDs (16/18, 89%). Less than 7% of women received counseling on a contraception plan, and 18% of subjects received counseling on a pregnancy plan.

CONCLUSIONS

Most WWE of childbearing ability taking potentially teratogenic AEDs were not using contraception. Those using contraception frequently had a method that has a significant drug-drug interaction which reduces the effectiveness of contraception. Women with epilepsy of childbearing ability prescribed an AED should be using effective contraception or participating in active discussions about pregnancy planning to avoid unplanned pregnancies and possible teratogenic effects of these AEDs. Documentation about pregnancy planning or contraceptive use in WWE of childbearing ability is minimal and should be discussed at least annually. It is critical for providers to discuss with WWE of childbearing ability the benefits and risks of various AED treatments; the need to select appropriate, effective contraception when pregnancy is not desired; and the importance of counseling regarding contraceptive or pregnancy planning.

Beyond medical diagnosis: Factors contributing to life satisfaction of women with epilepsy in Israel

This study was an exploratory study aimed to examine the contribution of both objective variables (such as education, occupational status, and leisure activity) and subjective variables (such as perceived disability, body image, and feminine self-image) to the life satisfaction of women with epilepsy in Israel. The study also sought to compare the findings with earlier studies of women with epilepsy or other disabilities in order to identify similar patterns in their life satisfaction. The study included 70 women, who had applied in the past to the Israel Epilepsy Association to obtain information and leisure activities. They were asked about their degree of life satisfaction in the context of their personal data including occupational status, leisure activity, perceived disability, body image, and feminine self-image. Findings indicated that higher education and perception of body image and femininity were positively correlated with higher life satisfaction. The regression model showed that perceived severity of disability and body image had the highest contribution to satisfaction with life, a fact that attests to the paramount importance of women's perception of their health disability in dealing with the disorder. These findings are discussed in relation to earlier comparative studies of those with/without epilepsy. The implications for practice suggest aspects that ought to be included in therapeutic interventions such as including contents related to feminine self-image and body image in the rehabilitation process as well as recommendations for future studies.

Folate use in women with epilepsy: predictors of adherence in a specialized tertiary outclinic

PURPOSE OF THE STUDY

The aims of this study were to determine the percentage of women with epilepsy (WWE) taking folic acid (FA) in an outpatient epilepsy tertiary hospital at São Paulo, Brazil, and to identify the possible predictors of adherence.

METHOD

Five hundred seventy-six medical records of patients followed in our service were reviewed. Sixty-six WWE using antiepileptic drugs with age between 16 and 52, sexually active but not in menopausal period, not pregnant, and not sterilized or with vasectomized partners underwent direct interviews with a prestructured questionnaire. Logistic regression with clinical and demographic variables using a stepwise method was performed to identify predictable variables of folate use.

RESULTS

We found 42.40% of FA intake. Hormonal contraceptive method use was an independent variable negatively associated with adherence to folate. Additionally, educational level was an independent variable positively associated with adherence to folate in WWE above 35years of age.

CONCLUSION

We found low folate adherence. Improved planning pre-conception for WWE should improve rates of effective folate supplementation.

WITHDRAWN: Preconception counselling for women with epilepsy to reduce adverse pregnancy outcome

Pregnancy-related knowledge and information needs of women with epilepsy: a systematic review

For women with epilepsy (WWE), pregnancy is complicated by considerations such as the potential teratogenicity of antiepileptic drugs (AEDs) versus the risks of having seizures during pregnancy. However, qualitative research suggests that many WWE remain uninformed about the risks associated with epilepsy and pregnancy and may, therefore, be making uninformed decisions about their families. The objectives of this review were to determine the level of patient knowledge, their informational needs, and whether these needs concerning pregnancy and childbirth issues are met among WWE. Electronic databases searched were PsycINFO, MEDLINE, Embase, CINAHL, and Web of Science. Studies were included if they used quantitative methods to survey WWE aged 16years or older about their knowledge, access to information, or informational needs specifically regarding epilepsy and pregnancy. Twelve studies were identified and assessed for research standards using the Quality Index. Overall Quality Index score was only 7.1 out of 14, indicating significant design limitations of many included studies, including highly selective sampling methods and the use of unvalidated outcome measures. There was a paucity of studies investigating specific areas of women's knowledge and information needs. Overall, WWE reported adequate awareness, but limited knowledge, of key issues regarding pregnancy and childbirth. Across studies, many women reported not receiving information about these issues. Evidence suggested that many WWE wanted to receive more information - particularly about the risks of AEDs for their offspring - well in advance of choosing an AED or planning pregnancy. Women aged under 35years wanted the most information. Preconception counseling received by many WWE appears insufficient, risking uninformed decision-making about pregnancy. Further research is needed to investigate the barriers that WWE face in accessing, receiving, and retaining appropriate information.

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.

Pregnancy, epilepsy, and women's issues

PURPOSE OF REVIEW

Optimal treatment of women with epilepsy includes consideration of the complex interactions of sex steroid hormones with epilepsy and antiepileptic drugs, and of the potential risks of any antiepileptic drug prescribed during a pregnancy.

RECENT FINDINGS

Clinical studies in women with epilepsy have provided a better foundation of knowledge about the complex relationships between cycling sex steroid hormones, seizure frequency, antiepileptic drugs, contraception, and neuroendocrine abnormalities. Pregnancy registries and observational studies have provided key data that allow for a better estimation of risks to the developing fetus.

SUMMARY

Understanding these key factors should enable informed treatment recommendations that can reduce adverse health effects in women with epilepsy and improve both seizure control and maternal and fetal outcomes.

Antiepileptic drugs during pregnancy in primary care: a UK population based study

OBJECTIVE

Antiepileptic drugs (AEDs) are commonly prescribed for epilepsy and bipolar disorder but little is known about their use in pregnancy. We examined secular trends in AED prescribing in pregnancy and pregnancy as a determinant for stopping AED prescribing.

METHODS

We identified 174,055 pregnancies from The Health Improvement Network UK primary care database. Secular trends in AED prescribing during pregnancy were examined between 1994 and 2009. We used Cox's regression analyses to compare time to discontinuation of AED prescriptions between pregnant and non-pregnant women and to identify predictors of discontinuation of AEDs in pregnancy.

RESULTS

Prescribing of carbamazepine and sodium valproate have declined since 1994 despite being the most commonly prescribed AEDs in pregnancy up to 2004. Prescribing of lamotrigine in pregnancy has steadily increased and has been the most popular AED prescribed in pregnancy since 2004. Pregnant women with epilepsy were twice as likely to stop receiving AEDs (Hazard Ratio (HR) 2.00, 95% Confidence Interval (CI) 1.62-2.47) when compared to non-pregnant women and for women with bipolar disorder this was even higher (HR 3.07, 95% CI 2.04-4.62). For pregnant women with epilepsy, those receiving AEDs less regularly before pregnancy were more likely to stop receiving AEDs in pregnancy.

CONCLUSIONS

Lamotrigine has been increasingly prescribed in pregnancy over older AEDs namely carbamazepine and sodium valproate. Pregnancy is a strong determinant for the discontinuation of AED prescribing particularly for women with bipolar disorder.

Women living with epilepsy, experiences of pregnancy and reproductive health: a review of the literature

PURPOSE

This study aimed to investigate the experiences of pregnancy in women living with epilepsy through a review and synthesis of existing literature.

METHODS

A comprehensive search of the literature was conducted in medical and social science databases to identify qualitative research, and questionnaires that included open-ended questions, which reported on the impact of epilepsy on the lives of pregnant women from preconception to post-delivery. The search was widened to include qualitative studies on pregnancy and issues of reproduction with women living with chronic illness that had at least one woman with epilepsy in the sample. The systematic search, carried out from April to June 2012, identified 17 publications that met the inclusion criteria, and 24 publications that did not. Qualitative results from these studies were categorised into: stage of pregnancy (preconception, pregnancy, and postnatal); case studies of patients' experiences; and the reproductive health experiences of women living with chronic illness.

RESULTS

One qualitative study was identified that directly investigated women's experiences of epilepsy during pregnancy. Many of the findings from the 16 remaining publications were found to be limited in generalisability due to small sample sizes and/or the poor quality of data.

CONCLUSION

Qualitative research on women's experiences of pregnancy whilst living with epilepsy is needed to address this critical gap in knowledge. This paper calls for improved preconception, pregnancy and postnatal supports and information for women living with this condition.

A qualitative study of the childbearing experience of women living with multiple sclerosis

PURPOSE

Although at any time in the UK, there are about 20,000 women with MS who may be considering having children, healthcare system often fails to provide them with information and support they need to make informed decisions about their health and pregnancy management. The aim of this paper is to explore the childbearing experience of women with MS to determine what support and information may be useful to this target group.

METHOD

Interviews were conducted with women with MS (n = 9). Transcripts were analysed using thematic analysis.

RESULTS

Three major themes emerged from the interviews with women living with MS. We found women were concerned about both medical and practical issues associated with having children. Limited access to information about relationships between MS and childbearing and receiving conflicting or wrong information was recounted. Opinions of family members and clinicians regarding having children in the context of MS impacted on women's experience of making decision about having children and childbearing.

CONCLUSIONS

Women with MS can benefit from having access to comprehensive, structured sources of information about MS and childbearing. Healthcare professionals and family members 'support could be channelled more appropriately to enhance their experience of making choices about childbearing.

Risk perception and medicines information needs in pregnant women with epilepsy--a qualitative study

PURPOSE

To explore risk perception and medicines information needs in pregnant women with epilepsy (WWE).

METHOD

In-depth interviews with pregnant WWE treated with antiepileptic drugs (AEDs).

RESULTS

Ten women aged 22-39 years in 20-34 weeks' gestation were interviewed. Avoiding seizures by taking AEDs in pregnancy outweighed perceived risks, but dose adjustments during and after pregnancy increased perceived risks of teratogenicity or seizures. The women had restrictive attitudes towards taking medicines for other indications than epilepsy. They appreciated their neurologist as a source for medicines information, though their needs for medicines information were reduced by long-term use of AEDs.

CONCLUSIONS

Pregnant WWE were confident in using AEDs through communication with their neurologist, but dose adjustments caused concern. Medicines information to pregnant WWE should focus on empowering the women to control the disease, supporting realistic risk perceptions of AEDs and other necessary medicines. In this article, we outline some medicines information strategies to pregnant WWE.

Patient knowledge about issues related to pregnancy in epilepsy: a cross-sectional study

In 2009, new guidelines were established by the American Academy of Neurology regarding pregnancy in women with epilepsy. A questionnaire was developed to assess patient knowledge of current guidelines related to epilepsy and pregnancy. Patients were recruited from a single outpatient clinic in a large Canadian tertiary care center. Patients were eligible to participate if they were female, of reproductive age, had active epilepsy for at least 6 months and were not cognitively impaired. One hundred women completed the survey (response rate 87%) with a median score of 40%. A significant association was found between total score and years of education (p<0.001). Significant associations were not found between total score and epilepsy duration (p=0.37), previously being pregnant (p=0.22), and polytherapy (p=0.31). Patient knowledge of the impact of epilepsy on pregnancy is low. More knowledge translation efforts are required to increase knowledge of issues related to pregnancy for women with epilepsy.

Knowledge and practice profile of obstetricians regarding epilepsy in women in Kerala state, India

Purpose:

To assess the knowledge of obstetricians about concerns of women with epilepsy.

Materials and Methods:

We surveyed 97 obstetricians (teaching hospitals—43, private hospitals—32, and community health centers–21) using knowledge of women's issues and epilepsy (KOWIE) questionnaire II with additional questions.

Results:

The mean duration of practice of the surveyed obstetricians was 12.4 ± 10.7 years and 94% were female doctors. Most of them were well informed about the teratogenic effects of AEDs (91%), need to continue antiepileptic drugs (AEDs) during pregnancy (95%), and the role of folic acid and vitamin K during pregnancy (95%). They agreed AEDs decrease the efficacy of oral contraception and it was safe for the woman to breast-feed the baby while on AEDs. Only 1/3^rd of them knew that steroid hormones could alter seizure threshold or that AEDs could predispose to osteomalacia. Fewer doctors knew that WWE could have increased sexual dysfunction (29.9%) or infertility (26.8%). The knowledge did not vary according to years of practice or practice settings.

Conclusions:

Obstetricians were well informed about the fetal complications of antenatal AED exposure, but were under informed of other complications such as osteomalacia, sexual dysfunction, and infertility.

Hormonal aspects of epilepsy

The relationships among hormones, epilepsy, and the medications used to treat epilepsy are complex, with tridirectional interactions that affect both men and women in various ways. Abnormalities of baseline endocrine status occur more commonly in people with epilepsy. Abnormalities are most often described for the sex steroid hormone axis, commonly presenting as sexual dysfunction in men and women with epilepsy and lower fertility. Other signs and symptoms in women with epilepsy include menstrual irregularities, premature menopause, and polycystic ovarian syndrome. The evaluation and care of adult patients with epilepsy should include considerations of the common hormonal aberrations that occur in this patient population. Questions about reproductive health disorders, sexual function, symptoms of thyroid disorders, and bone health should be part of the evaluation of all adult patients with epilepsy. Further laboratory or radiologic testing and referral to other specialists to participate in collaborative care may be warranted if underlying disorders are suspected, especially given that many of these hormone abnormalities can result in long-term health risks as well as negatively affect quality of life. AEDs and hormones have a bidirectional interaction that can impair the efficacy of contraceptive hormone treatments and of the AEDs. Endogenous hormones can influence seizure severity and frequency, resulting in catamenial patterns of epilepsy. However, this susceptibility to hormonal influences can be used to develop hormonal strategies to improve seizure control in women with epilepsy with use of cyclic PROG supplementation or alteration of the endogenous hormone release. Additionally, development of the neurosteroid analog ganaxolone provides a novel approach that can potentially be used across both genders and all age groups.

Monotherapy of epilepsy in women: psychiatric and neuroendocrine aspects

The aim of the present work was to perform a comparative assessment of the efficacy and safety of traditional and contemporary antiepileptic agents in women of reproductive age. The experimental group consisted of 65 patients, of whom 48 had partial epilepsy and 17 had idiopathic generalized epilepsy. A number of issues were addressed in studies of a larger group of patients (110), including both women (65) and men (45). The following agents were studied: Topamax, valproates, carbamazepine, and barbiturates, all used as monotherapy. Patients' status was evaluated using clinical (neurological, psychiatric), psychometric, neuropsychological, and hormonal parameters. The data led to the general conclusion that Topamax had advantages over the other study agents in the treatment of women with epilepsy.

Managing epilepsy in women of childbearing age

Epilepsy affects the menstrual cycle, aspects of contraception, fertility, pregnancy and bone health in women. It is common for seizure frequency to vary throughout the menstrual cycle. In ovulatory cycles, two peaks can be seen around the time of ovulation and in the few days before menstruation. In anovulatory cycles, there is an increase in seizures during the second half of the menstrual cycle. There is also an increase in polycystic ovaries and hyperandrogenism associated with valproate therapy. There are no contraindications to the use of non-hormonal methods of contraception in women with epilepsy. Non-enzyme-inducing antiepileptic drugs (AEDs) [valproate, benzodiazepines, ethosuximide, levetiracetam, tiagabine and zonisamide] do not show any interactions with the combined oral contraceptive (OC). There are interactions between the combined OC and hepatic microsomal-inducing AEDs (phenytoin, barbiturates, carbamazepine, topiramate [dosages>200 mg/day], oxcarbazepine) and lamotrigine. Pre-conception counselling should be available to all women with epilepsy who are considering pregnancy. Women with epilepsy should be informed about issues relating to the future pregnancy, including methods and consequences of prenatal screening, fertility, genetics of their seizure disorder, teratogenicity of AEDs, folic acid and vitamin K supplements, labour, breast feeding and care of a child. During pregnancy, the lowest effective dose of the most appropriate AED should be used, aiming for monotherapy where possible. Recent pregnancy databases have suggested that valproate is significantly more teratogenic than carbamazepine, and the combination of valproate and lamotrigine is particularly teratogenic. Most pregnancies in women with epilepsy are without complications, and the majority of infants are delivered healthy with no increased risk of obstetric complications in women. There is no medical reason why a woman with epilepsy cannot breastfeed her child. The AED concentration profiled in breast milk follows the plasma concentration curve. The total amount of drug transferred to infants via breast milk is usually much smaller than the amount transferred via the placenta during pregnancy. However, as drug elimination mechanisms are not fully developed in early infancy, repeated administration of a drug such as lamotrigine via breast milk may lead to accumulation in the infant. Studies have suggested that women with epilepsy are at increased risk of fractures, osteoporosis and osteomalacia. No studies have been undertaken looking at preventative therapies for these co-morbidities.

Gender-specific psychosocial impact of living with epilepsy

Although many psychosocial issues affect all people living with epilepsy, certain issues either are specific to one gender or have a different prevalence or significance between men and women with epilepsy. Most studies suggest that the incidence of epilepsy is slightly higher in males with epilepsy. Sexual dysfunction is common among men and women with epilepsy and has been related to epilepsy type and treatment. Women living with epilepsy are often prone to increased seizure frequency at certain phases of their menstrual cycles. Hormone replacement therapy in postmenopausal women may worsen seizures. Treatment during pregnancy is often a precarious balancing act between the teratogenic risks of AEDs and the maintenance of maternal seizure control. However, pregnancy registries and other prospective studies have given us invaluable information on how to optimize treatment regimens as well as information about safety of breastfeeding. These gender-specific factors should be a key consideration when counseling and treating patients with epilepsy.

Written information about individual medicines for consumers

BACKGROUND

Medicines are the most common intervention in most health services. As with all treatments, those taking medicines need sufficient information: to enable them to take and use the medicines effectively, to understand the potential harms and benefits, and to allow them to make an informed decision about taking them. Written medicines information, such as a leaflet or provided via the Internet, is an intervention that may meet these purposes.

OBJECTIVES

To assess the effects of providing written information about individual medicines on relevant patient outcomes (knowledge, attitudes, behaviours and health outcomes) in relation to prescribed and over-the-counter medicines.

SEARCH STRATEGY

We searched MEDLINE, EMBASE, CINAHL, The Cochrane Library, PsycINFO and other databases to March 2007. We handsearched five journals' tables of contents, and the reference lists of included studies, and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of medicine users, comparing written medicines information with no written medicines information; or trials that compared two or more styles of written medicines information. We only included trials that measured a knowledge, attitudinal or behavioural outcome. There were no language restrictions.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data relating to the interventions, methods of the trials, and outcome measures; and reconciled differences by discussion. Heterogeneity of interventions and outcomes measured meant that data synthesis was not possible. The results are presented in narrative and tabular format.

MAIN RESULTS

We included 25 RCTs involving 4788 participants. Six of twelve trials showed that written information significantly improved knowledge about a medicine, compared with no written information. The inability to combine results means we cannot conclude whether written information was effective for increasing knowledge. The results for attitudinal and behavioural outcomes were mixed. No studies showed an adverse effect of medicines information.

AUTHORS' CONCLUSIONS

The combined evidence was not strong enough to say whether written medicines information is effective in changing knowledge, attitudes and behaviours related to medicine taking. There is some evidence that written information can improve knowledge. The trials were generally of poor quality, which reduces confidence in the results. Trials examining the effects of written information need to be better designed and use consistent and validated outcome measures. Trials should evaluate internet-based medicines information. It is imperative that written medicines information be based on best practice for its information design and content, which could improve its effectiveness in helping people to use medicines appropriately.

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

OBJECTIVE

The purpose of this Cochrane review was to determine the effectiveness of delivering preconception counseling interventions to women with epilepsy (WWE) as a means of reducing adverse pregnancy outcomes, increasing knowledge, and increasing intentions to plan pregnancy.

METHODS

Two hundred twenty-five citations were retrieved from a systematic search of the Cochrane Library and electronic databases: Medline (OVID), Scopus, CINAHL, PsychINFO, and ASSIA, and hand searches of relevant epilepsy and obstetric journals.

RESULTS

The search strategy identified 11 studies for consideration for inclusion. However, none met the required criteria for inclusion.

CONCLUSIONS

There is no robust evidence to inform the content, methods of delivery, or likely effectiveness of preconception counseling to improve pregnancy outcomes for WWE and their offspring. The value of counseling WWE prior to conception remains uncertain and requires evaluation in well-designed studies, appropriately powered to detect changes likely associated with both maternal and infant outcomes.

Antiepileptic drugs during pregnancy: what is known and which AEDs seem to be safest?

Most infants born to women with epilepsy are healthy, but there are increased risks related to in utero antiepileptic drug (AED) exposure and seizures. Emerging data from pregnancy registries and other studies allow us to better balance the anatomic teratogenic and neurodevelopmental effects of AEDs against the need to maintain maternal seizure control. Several large prospective pregnancy registries demonstrate a consistent pattern of increased risk for major congenital malformations (MCMs) with valproate (VPA) use as monotherapy, compared to nonexposed populations and to other AEDs used in monotherapy. AED polytherapy likely increases risk for MCMs, but the risk is more pronounced if VPA is included. Reduced cognitive outcomes have been reported with AED polytherapy, and with use of VPA, phenobarbital (PB), and PHT as monotherapy. Dose-dependent risk has been demonstrated with VPA for MCMs and cognitive consequences. CBZ groups show normal neurodevelopment. Increased clearance of most of the AEDs occurs during pregnancy. Use of therapeutic drug monitoring during pregnancy with LTG reduces the risk for seizure worsening. The consistent findings of increased teratogenic risk for VPA should discourage use of this medication as first-line treatment in women of childbearing age.

Preconception counselling for women with epilepsy to reduce adverse pregnancy outcome

BACKGROUND

The provision of preconception counselling to women with epilepsy (WWE) has become established as recommended practice and includes a review of drug treatment and the provision of information and advice on both seizure and treatment-related risks to both mother and child. In this review we assess the evidence regarding the effectiveness of preconception counselling for WWE.

OBJECTIVES

To determine the effectiveness of preconception counselling for WWE, measured by a reduction in adverse pregnancy outcome in both mother and child; increased knowledge of preconception issues in WWE and increasing intention to plan pregnancy.

SEARCH STRATEGY

We searched the Epilepsy Group's Specialized Register (30/01/2008), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2007, Issue 4), and electronic databases: MEDLINE (OVID) (1950-February 2008); SCOPUS (1966-March 2008); CINAHL (1982-March 2008); PsyclNFO (1806-March 2008); ASSIA (1987-March 2008).

SELECTION CRITERIA

Randomised control trials; including cluster and quasi-randomised trials, prospective cohorts, controlled before and after studies, and interrupted time series that compared the outcomes in mothers with epilepsy and infants of mothers with epilepsy who received preconception counselling, to the outcomes of mothers with epilepsy and their infants who received standard care or no intervention.

DATA COLLECTION AND ANALYSIS

The methodological quality of potentially relevant studies were assessed to determine appropriate inclusion. Where necessary, study authors were contacted for additional information. No studies met the review inclusion criteria.

MAIN RESULTS

The search strategy identified 11 studies for consideration of inclusion. However, none met the required criteria for inclusion.

AUTHORS' CONCLUSIONS

There is no evidence to inform the content, methods of delivery or effectiveness of preconception counselling to improve pregnancy outcomes for WWE and their offspring. The value of counselling delivered to WWE prior to conception, with the intention of reducing the risks of adverse outcome in mother and child, requires evaluation in well-designed studies, appropriately powered to detect changes in both maternal and infant outcome.

Problems that mothers’ with epilepsy experience when caring for their children

Women with epilepsy who were service users of Epilepsy Action in the United Kingdom (UK) completed a questionnaire on the risks of caring for their baby and whether they were provided with useful information on fulfilling their caring role (Epilepsy Action is the trading name of the British Epilepsy Association a major UK charity for those with epilepsy). The cohort of 84 all reported some problems. The following were rated as being the most problematic; caring for their baby outside the home and bathing, whereas breastfeeding was rated as much less problematic. Some problems were rated as severe, which meant some babies were put at undue risk. Approximately 50% had been provided with information about caring and managing risk. Eighty-six percent found this information useful. The main conclusion is that more extensive, well-planned research is needed on this topic. There is virtually nothing in the academic literature to guide practice and this is needed. Present guidelines tend only to cover what the women rate as less problematic, e.g. breastfeeding, whereas what they rate highly problematic is often not covered. This needs attention in updates.
