Bipolar Disorder in Pregnancy and Postpartum: Principles of Management

Women's Experiences With a Pregnancy Relapse Prevention Plan to Prevent Mental Health Symptom Relapse

OBJECTIVE

To describe the experiences of women with a mental health diagnosis with making and using a pregnancy relapse prevention plan (PRPP) in an effort to prevent mental health symptom relapse during the period of pregnancy, birth, and postpartum.

DESIGN

Qualitative design with a phenomenological approach.

SETTING

Participants were recruited from an outpatient clinic within a "psychiatry and pregnancy" mental health institute in the Netherlands.

PARTICIPANTS

Twelve women with a mental health diagnosis who gave birth.

MEASUREMENTS

Data were collected by individual semistructured interviews supported by a topic list.

RESULTS

Four categories/themes of findings emerged from the data: Making and Advantage of the PRPP, Using the PRPP, Cooperation, and Care After Childbirth.

CONCLUSION

Making and using a PRPP provided pregnant women with overview, predictability, and feelings of tranquility on all aspects related to pregnancy, childbirth, and the postpartum period. Participants appreciated the support and recognition the PRPP provided. The signal function of the PRPP for all who were involved (professional and nonprofessional caregivers) was described as an added value. Involvement of women's partners and caretakers was essential. An evaluation afterward is recommended.

Global trends and hotspots in pain associated with bipolar disorder in the last 20 years: a bibliometric analysis

Purpose

The prevalence of comorbid pain and Bipolar Disorder in clinical practice continues to be high, with an increasing number of related publications. However, no study has used bibliometric methods to analyze the research progress and knowledge structure in this field. Our research is dedicated to systematically exploring the global trends and focal points in scientific research on pain comorbidity with bipolar disorder from 2003 to 2023, with the goal of contributing to the field.

Methods

Relevant publications in this field were retrieved from the Web of Science core collection database (WOSSCC). And we used VOSviewer, CiteSpace, and the R package "Bibliometrix" for bibliometric analysis.

Results

A total of 485 publications (including 360 articles and 125 reviews) from 66 countries, 1019 institutions, were included in this study. Univ Toront and Kings Coll London are the leading research institutions in this field. J Affect Disorders contributed the largest number of articles, and is the most co-cited journal. Of the 2,537 scholars who participated in the study, Stubbs B, Vancampfort D, and Abdin E had the largest number of articles. Stubbs B is the most co-cited author. "chronic pain," "neuropathic pain," "psychological pain" are the keywords in the research.

Conclusion

This is the first bibliometric analysis of pain-related bipolar disorder. There is growing interest in the area of pain and comorbid bipolar disorder. Focusing on different types of pain in bipolar disorder and emphasizing pain management in bipolar disorder are research hotspots and future trends. The study of pain related bipolar disorder still has significant potential for development, and we look forward to more high-quality research in the future.

Depression Treatment in Pregnancy: Is It Safe, or Is It Not?

Prenatal depression carries substantial risks for maternal and fetal health and increases susceptibility to postpartum depression. Untreated depression in pregnancy is correlated with adverse outcomes such as an increased risk of suicidal ideation, miscarriage and neonatal growth problems. Notwithstanding concerns about the use of antidepressants, the available treatment options emphasize the importance of specialized medical supervision during gestation. The purpose of this paper is to conduct a brief literature review on the main antidepressant drugs and their effects on pregnancy, assessing their risks and benefits. The analysis of the literature shows that it is essential that pregnancy be followed by specialized doctors and multidisciplinary teams (obstetricians, psychiatrists and psychologists) who attend to the woman's needs. Depression can now be treated safely during pregnancy by choosing drugs that have no teratogenic effects and fewer side effects for both mother and child. Comprehensive strategies involving increased awareness, early diagnosis, clear guidelines and effective treatment are essential to mitigate the impact of perinatal depression.

Management of Lithium Dosing Around Delivery: An Observational Study

Objectives

Recommendations on lithium dosing around delivery vary, with several guidelines suggesting that lithium should be discontinued prior to delivery. We aimed to evaluate the validity of these recommendations by investigating 1) maternal lithium blood level changes following delivery, and 2) the association between neonatal lithium blood levels at delivery and neonatal outcomes.

Methods

In this retrospective observational cohort study, we included women with at least one lithium blood level measurement during the final week of pregnancy and the first postpartum week. For aim 2, we included a subcohort of women with neonates for whom neonatal lithium blood levels (obtained from the umbilical cord or a neonatal vein puncture within 24 hours of delivery) were available.

Results

There were a total of 233 maternal lithium blood level measurements; 55 (23.6%) in the week before delivery and 178 (76.4%) in the week after. There was no association between time and lithium blood level/dose ratio (Pearson correlation coefficient -0.03, P = .63). Additionally, we included a total of 29 neonates for whom a lithium measurement was performed within 24 hours postpartum. Maternal and neonatal lithium blood levels were strongly correlated. We observed no associations between neonatal lithium blood levels at delivery and neonatal outcomes.

Conclusion

Based on our findings, we do not recommend lowering the dosage or discontinuation of lithium prior to delivery. Stable dosing can prevent subtherapeutic lithium serum levels, which is especially important in the postpartum period when relapse risks are highest.Appeared originally in Bipolar Disord 2021; 23:49-54.

Striking the Balance: Bipolar Disorder in the Perinatal Period

The authors reviewed the literature, published between 2018 and 2023, on treating bipolar disorder in the perinatal period in order to summarize current treatment perspectives. Mood episodes occur during pregnancy and there are high rates of both initial onset and recurrence in the postpartum period. Bipolar disorder itself is associated with higher risks of adverse pregnancy outcomes, including gestational hypertension, hemorrhage, cesarean delivery, and small for gestational age infants. A general principle of perinatal treatment includes maintaining psychiatric stability of the pregnant person while reducing medication exposure risk to the fetus. A variety of factors can compromise psychiatric stability, including rapid discontinuation of stabilizing medications, decreased efficacy due to physiologic changes of pregnancy, and exacerbation of underlying psychiatric illness. Psychosocial interventions include optimizing sleep, increasing support, and reducing stress. The American College of Obstetricians and Gynecologists recommends against discontinuing or withholding medications solely due to pregnancy or lactation status. Individualized treatment involves a discussion of the risks of undertreated bipolar disorder weighed against the risks of individual medication choice based on available evidence regarding congenital malformations, adverse neonatal and obstetrical events, and neurodevelopmental outcomes. Valproate is not a first-line treatment due to higher risks. Data are lacking on safety for many newer medications. The authors review current safety data regarding lithium, lamotrigine, and antipsychotics, which are the most commonly used treatments for managing bipolar disorder in the perinatal period. Due to physiologic changes during pregnancy, frequent therapeutic drug monitoring and dose adjustments are required.

Prophylactic Management of Women With Bipolar Disorder During Pregnancy and the Perinatal Period: Clinical Scenario-Based Practical Recommendations From A Group of Perinatal Psychiatry Authors

ABSTRACT

Many women with bipolar disorder experience episodes of illness or relapses over the perinatal period, especially in the immediate postpartum period. Risks associated with treated/untreated psychopathologies and fetal exposure to bipolar medications make the management of bipolar disorder during these periods challenging for clinicians and patients. In light of the available effectiveness and reproductive safety data, the current clinical update based on the opinions of a group of international perinatal psychiatry authors recommends general considerations and specific management strategies for each possible clinical scenario, including mixed features, predominant polarity, diagnosis of subtypes of bipolar disorder, severity of previous episodes, and risk of recurrence of mood episodes.

Psychiatric Treatment in Pregnancy: A Narrative Review

Pregnancy, childbirth and the puerperium are a series of transformations and huge changes in a woman's life, which may also be accompanied by various mental problems. Very often, women experiencing mental disorders during this period and their doctors face a decision on safety of treatment. The purpose of the following review was to assess the safety of treatment during pregnancy. Internet scientific database PubMed was searched. There are groups of psychiatric medications contraindicated during pregnancy such as valproates as well as relatively safe ones such as selective serotonin reuptake inhibitors (SSRIs) or antipsychotics. However, in every clinical situation, a decision should be made with caution, based on individual characteristics of patient, severity of disorder and clinical picture.

Comparison of the probability of four anticonvulsant mood stabilizers to facilitate polycystic ovary syndrome in women with epilepsies or bipolar disorder-A systematic review and meta-analysis

Background

Patients treated with anticonvulsant mood stabilizers have a higher incidence of polycystic ovary syndrome (PCOS). However, there is no comparison between different anticonvulsant mood stabilizers. The purpose of this study was to systematically evaluate the prevalence of PCOS in women taking anticonvulsant mood stabilizers and compare the probability of PCOS caused by different anticonvulsant mood stabilizers.

Methods

Five databases, namely PubMed, Embase, Web of Science, Cochrane Library, and Clinical Trials, were searched for literature on anticonvulsant mood stabilizers and PCOS published up to October 28, 2022. This meta-analysis was performed using Revman 5.4, Stata 14.0, and R4.1.0, and effect size pooling was performed in fixed- or random-effects models based on the results of I² and Q-test, and the surface under the cumulative ranking curve (SUCRA) was used for analysis to assess the cumulative probability of drug-induced PCOS. Publication bias was assessed by funnel plot Egger's test and meta regression.

Results

Twenty studies with a total of 1,524 patients were included in a single-arm analysis, which showed a combined effect size (95% CI) of 0.21 (0.15-0.28) for PCOS in patients taking anticonvulsant mood stabilizers. Nine controlled studies, including 500 patients taking medication and 457 healthy controls, were included in a meta-analysis, which showed OR = 3.23 and 95% CI = 2.19-4.76 for PCOS in women taking anticonvulsant mood stabilizers. Sixteen studies with a total of 1416 patients were included in a network meta-analysis involving four drugs, valproate (VPA), carbamazepine (CBZ), oxcarbazepine (OXC), and lamotrigine (LTG), and the results of the network meta-analysis showed that VPA (OR = 6.86, 95% CI = 2.92-24.07), CBZ (OR = 3.28, 95% CI = 0.99-12.64), OXC (OR = 4.30, 95% CI = 0.40-49.49), and LTG (OR = 1.99, 95% CI = 0.16-10.30), with cumulative probabilities ranked as VPA (90.1%), OXC (63.9%), CBZ (50.1%), and LTG (44.0%).

Conclusion

The incidence of PCOS was higher in female patients treated with anticonvulsant mood stabilizers than in the healthy population, with VPA having the highest likelihood of causing PCOS. The most recommended medication when considering PCOS factors is LTG.

Management of Bipolar Disorder During the Perinatal Period

Bipolar disorder (BPD) is a lifelong mental health condition characterized by symptoms of mania, depression, and often anxiety. BPD can have detrimental consequences for individuals during pregnancy and the postpartum period, as well as for their offspring. This is often due to underdiagnosis and/or misdiagnosis as unipolar depression. There is a high incidence of first episodes of BPD in pregnant and postpartum persons. Perinatal care providers need to routinely screen for BPD and assess for relapse among those with a previous diagnosis during the pregnancy and postpartum periods. Medication management is complex and must be considered in the context of an individual's risk factors and perceptions about treatment as well as the limited evidence regarding fetal safety, using a shared decision-making model. Collaboration, consultation, and/or referral to mental health care providers are essential for managing acute and chronic BPD symptoms.

Fire and Darkness: On the Assessment and Management of Bipolar Disorder

Bipolar disorder is characterized by recurrent mood episodes, affecting 1% to 2% of the population. Although its defining features are manic and hypomanic episodes, its course is dominated by depressive syndromes. Diagnosis can be challenging owing to symptom overlap with other disorders. Management goals include early and complete remission of acute episodes and the prevention of relapse between episodes. We present an overview of bipolar disorder and its subtypes, including algorithms and suggestions for screening, assessment, and treatment.

Cost-effectiveness of mental health interventions during and after pregnancy: A systematic review

BACKGROUND

Mental health problems during and after pregnancy such as depression, anxiety, post-traumatic stress disorder (PTSD), or addiction are common and can have lifelong implications for both parents and offspring. This review investigates the cost-effectiveness of interventions tackling these problems, assesses the methodological quality of included studies, and indicates suggestions for further research.

METHODS

Thirteen databases were searched for economic evaluations of interventions related to antenatal, perinatal, and postnatal mental health conditions, published between 2000 and September 2021, in high-income countries.

RESULTS

Thirty-nine studies met all inclusion criteria. Interventions considered were screening programs, pharmacological treatments, and various forms of psychosocial and psychological support. Six studies reported that the intervention was cost-saving. Eighteen were cost-effective and seven likely to be cost-effective. Only six studies included health outcomes for the child; one study considered paternal health. The time horizon for which costs and consequences were considered was for most evaluations limited to 1 year (n = 18) or 2 years (n = 11) postpartum.

CONCLUSIONS

Given the importance of the subject, a relatively low number of studies have investigated the cost-effectiveness of interventions tackling mental health problems during and after pregnancy. The scant evidence available suggests good overall value for money. Likely, cost-effectiveness is underestimated as costly long-term consequences on offspring are systematically excluded. No evidence was found for several frequently occurring conditions. Further research is required to obtain reliable, long-term effectiveness data and to address the methodological challenges related to measuring all relevant health outcomes for all parties affected.

Bipolar disorder: Treatment strategies for women of childbearing age

PURPOSE

Bipolar disorder is associated with increased rates of morbidity and mortality, magnified in women of childbearing age. The purpose of this paper is to provide an overview of the differential diagnosis and management of bipolar disorder in women of childbearing age.

CONCLUSIONS

Differential diagnoses for bipolar disorder include depressive disorders, anxiety disorders, trauma-related disorders, attention-deficit/hyperactivity disorder, and personality disorders. Pharmacotherapeutic options for the treatment of bipolar disorder include lithium, anti-epileptic medications, and atypical antipsychotics. In regard to women of childbearing age, consideration of risks, benefits, and alternative therapies is needed before initiating therapy.

PRACTICE IMPLICATIONS

Caring for patients with bipolar disorder, particularly women of childbearing age, requires careful differentiation of bipolar disorder from other mental health problems, and prudent consideration of pharmacotherapeutic options.

Olanzapine and quetiapine in the prevention of a new mood episode in women with bipolar disorder during the postpartum period: a retrospective cohort study

OBJECTIVE

To examine whether olanzapine and quetiapine are useful in the prevention of a new mood episode during the postpartum period.

METHODS

Data on 23 patients (n=14 for olanzapine and n=9 for quetiapine) with bipolar disorder who met the criteria for this study were retrospectively gathered. The diagnosis of bipolar disorder was determined by means of the DSM-IV.

RESULTS

The mean follow-up period was 33.95±12.07 weeks. Six (26.1%) of 23 patients experienced recurrent mood episodes during the postpartum period. Four of these six patients were taking olanzapine and two were taking quetiapine. Patients with recurrent mood episodes had a significantly stronger family history of bipolar disorder, higher number of past episodes, and earlier onset and longer duration of illness compared to patients without recurrent mood episodes.

CONCLUSION

Monotherapy with olanzapine or quetiapine can be considered as an alternative to mood stabilizers in preventing the development of new mood episodes after childbirth.

Management of lithium dosing around delivery: An observational study

For aim 2, we included a subcohort of women with neonates for whom neonatal lithium blood levels (obtained from the umbilical cord or a neonatal vein puncture within 24 hours of delivery) were available.

RESULTS

There were a total of 233 maternal lithium blood level measurements; 55 (23.6%) in the week before delivery and 178 (76.4%) in the week after. There was no association between time and lithium blood level/dose ratio (Pearson correlation coefficient -0.03, P = .63). Additionally, we included a total of 29 neonates for whom a lithium measurement was performed within 24 hours postpartum. Maternal and neonatal lithium blood levels were strongly correlated. We observed no associations between neonatal lithium blood levels at delivery and neonatal outcomes.

CONCLUSION

Based on our findings, we do not recommend lowering the dosage or discontinuation of lithium prior to delivery. Stable dosing can prevent subtherapeutic lithium serum levels, which is especially important in the postpartum period when relapse risks are highest.

The 2020 Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for mood disorders

OBJECTIVES

To provide advice and guidance regarding the management of mood disorders, derived from scientific evidence and supplemented by expert clinical consensus to formulate s that maximise clinical utility.

METHODS

Articles and information sourced from search engines including PubMed, EMBASE, MEDLINE, PsycINFO and Google Scholar were supplemented by literature known to the mood disorders committee (e.g. books, book chapters and government reports) and from published depression and bipolar disorder guidelines. Relevant information was appraised and discussed in detail by members of the mood disorders committee, with a view to formulating and developing consensus-based recommendations and clinical guidance. The guidelines were subjected to rigorous consultation and external review involving: expert and clinical advisors, key stakeholders, professional bodies and specialist groups with interest in mood disorders.

RESULTS

The Royal Australian and New Zealand College of Psychiatrists mood disorders clinical practice guidelines 2020 (MDcpg²⁰²⁰) provide up-to-date guidance regarding the management of mood disorders that is informed by evidence and clinical experience. The guideline is intended for clinical use by psychiatrists, psychologists, primary care physicians and others with an interest in mental health care.

CONCLUSION

The MDcpg²⁰²⁰ builds on the previous 2015 guidelines and maintains its joint focus on both depressive and bipolar disorders. It provides up-to-date recommendations and guidance within an evidence-based framework, supplemented by expert clinical consensus.

Indirect psychiatric consultation for perinatal bipolar disorder: A scoping review

OBJECTIVE

To synthesize the literature and develop guidance on supports needed for primary care and perinatal providers in screening, initial management, triage, and bridging treatment for perinatal bipolar disorder.

METHODS

We conducted a scoping review by searching six electronic databases using keywords related to perinatal bipolar disorder. We summarized descriptive statistics on settings and extracted information on care approaches. We synthesized the literature on indirect care models and extracted data on screening, follow-up, referrals, and management.

RESULTS

1169 articles were retrieved. 51 articles were included after review. Most papers were reviews. Fewer addressed care in obstetric (n = 20, 39%), primary care (n = 10, 20%), and pediatric settings (n = 2, 4%). Most papers (n = 30, 59%) discussed using screening instruments for bipolar disorder. Articles were mixed on recommendations for bipolar disorder screening.

CONCLUSIONS

Varied strategies for structured assessment exist and are influenced by practice setting. There remains uncertainty about optimal strategies for screening and management of perinatal bipolar disorder. We recommend screening for bipolar disorder in the perinatal period in select circumstances (with depression screening, known bipolar disorder risk factors, and prior to starting antidepressants). If specialty mental health care is unavailable, we recommend enhancing usual care through integrated care strategies such as indirect consultation.

Pharmacological prevention of mood episodes in women with bipolar disorder during the perinatal period: A systematic review of current literature

OBJECTIVE

This review examined the efficacy of mood stabilizers and antipsychotics in patients with bipolar disorder during pregnancy and the postpartum period.

METHODS

PubMed was searched for reports between 01 January 1996 and 31 December 2019 by using combinations of key words bipolar disorder, pregnancy, postpartum period, puerperium, prophylaxis, mood stabilizers, antipsychotics, lithium, lamotrigine, valproate, carbamazepine, oxcarbazepine, olanzapine, risperidone, quetiapine, aripiprazole, haloperidol, and chlorpromazine.

RESULTS

The present reports included a total of 256 patients using lithium (n = 143), lamotrigine (n = 73), valproate (n = 17), olanzapine (n = 17), quetiapine (n = 4) and haloperidol (n = 1) during pregnancy or the postpartum period. Recurrence rates in pregnant patients using lithium (n = 79) and lamotrigine (n = 17) were 22.7 % and 41.2 %, respectively. According to very limited data, none of the patients using valproate (n = 2), quetiapine (n = 3) or olanzapine (n = 6) experienced a new episode during pregnancy. A recurrence was reported in 12 (70.6 %) of 17 patients using valproate during the postpartum period. The same recurrence rates in patients using lithium (n = 123), lamotrigine (n = 63), olanzapine (n = 17) and quetiapine (n = 3) were 20.3 %, 7.9 %, 11.7 %, and 33.3 %, respectively.

CONCLUSIONS

This review suggests that lithium, lamotrigine and olanzapine seem to be effective in preventing new mood episodes in patients with bipolar disorder during the perinatal period.

Affective disorders: A question of continuing treatment during pregnancy (Review)

Fetal development, especially in the first trimester, has proven to be heavily influenced by external factors, such as chemical intake of medication. Chronic psychiatric treatment might interfere with the anatomical and physiological wellbeing of the fetus, because psychotropic medication proceeds past the placenta, into the amniotic fluid, and can enter breast milk. Hence some of the medications prescribed for mood disorders should be reconsidered during pregnancy, without sub-optimally treating when it is needed. A literature review is presented which systematically collects modern data and synthesizes previous interdisciplinary research findings on the safety of psychiatric treatment for affective disorders during pregnancy (term-based) and lactation. Antidepressants and mood stabilizers, fundamental strategies in treating affective disorders, have been classified by the FDA as C respectively D drugs pertaining to their risk, with some exception. Most guidelines recommend pharmacologically treating moderate-severe depression, preferably with SSRIs. Evidence advocates that drugs should be used during pregnancy only if clearly needed and the benefit outweighs the risk to the fetus. However, guidelines the American College of Obstetricians and Gynecologists state that antidepressants are a preferred first course of treatment and does not take into account the severity of the depression. Among mood-stabilizers, lithium is considered to be the safest option for pregnant women. Anticonvulsants have a higher risk of teratogenicity compared with lithium, with lamotrigine being the safest one. All mood stabilizers should be recommended in the lowest effective doses. There is controversy regarding the safety of second-generation antipsychotics during pregnancy and further research is required. Several case reports and meta-reviews have been published in order to emphasize the safety of electroconvulsive therapy (ECT) during pregnancy, but practitioners still stigmatize this procedure. Evaluating the overall risk-benefit ratio should be assessed by the medical care provider, taking into consideration current findings.

Lithium Use and Non-use for Pregnant and Postpartum Women with Bipolar Disorder

PURPOSE OF REVIEW

Despite being recognized as a first-line treatment for bipolar disorder, there is still inconsistent use of lithium in perinatal populations. This article will review data regarding lithium use during the peripartum and provide management recommendations for general psychiatric clinicians.

RECENT FINDINGS

In contrast to prior data, recent studies indicate that lithium use in pregnancy is associated with either no increased malformations risk or a small increase in risk for cardiac malformations including Ebstein's anomaly. Limited data also show no significant effect on obstetric or neurodevelopmental outcomes. Data regarding infant lithium exposure via breastmilk remains limited. Lithium is currently under-prescribed and is an important treatment for women with bipolar disorder in pregnancy and the postpartum. Clinicians must weigh the risk of lithium treatment versus the risk of withholding or changing lithium treatment when managing bipolar disorder in this population.

Clinical Lactation Studies of Lithium: A Systematic Review

Background: There is substantial evidence that postpartum prophylaxis with lithium lowers the rate of relapse in bipolar disorder. However, it is contraindicated during breastfeeding due to the high variability of the transfer into breast milk. Aims: We conducted a systematic review of the current evidence of studies assessing the transfer of lithium to lactating infants and short-term infant outcomes. Methods: An a priori protocol was designed based on PRISMA guidelines. Searches in PubMed and LactMed were conducted until September 2018. Studies assessing lithium pharmacokinetic parameters and short-term infant outcomes were included. Quality was assessed using a checklist based on international guidelines (i.e., FDA). Results: From 344 initial studies, 13 case reports/series with 39 mother-child dyads were included. Only 15% of studies complied with ≥50% of the items on the quality assessment checklist. Infants breastfeed a mean (SD) of 58.9 (83.3) days. Mean maternal lithium dose was 904 (293) mg/day, corresponding lithium plasma/serum concentration was 0.73(0.26) mEq/L, and breast milk concentration was 0.84(0.14) mEq/L. Mean infant lithium plasma/serum concentration was 0.23(0.26) mEq/L. Twenty-six (80%) infants had concentrations ≤0.30 mEq/L without adverse effects. Eight (20%) showed a transient adverse event (i.e., acute toxicity or thyroid alterations). All of them were also prenatally exposed to lithium monotherapy or polytherapy. Conclusion: The current evidence comes from studies with a degree of heterogeneity and of low-moderate quality. However, it identifies areas of improvement for future clinical lactation studies of lithium and provides support for some clinical recommendations.

Psychopharmacological Decision Making in Bipolar Disorder During Pregnancy and Lactation: A Case-by-Case Approach to Using Current Evidence

The safety of pharmacotherapy for bipolar disorder during pregnancy and lactation remains a subject of debate and uncertainty. Clinicians must balance concerns about anatomical and behavioral teratogenicity, maternal mental health, exposure to multiple drugs, and heightened risks for peripartum mood episodes. Risk-benefit analyses must consider factors such as illness severity, past pregnancy treatment outcomes, known drug responsivity, psychosocial supports, and key windows during fetal development. Pharmacological decision making usually changes over the course of pregnancy, given developments in maternal physiology and critical relapse risk periods. Among mood stabilizers, given current research, many experts eschew divalproex and carbamazepine, consider lamotrigine relatively benign, and voice strong opinions for or against lithium. Most second-generation antipsychotics are considered relatively safe, apart from possible extrapyramidal and other motor signs of withdrawal after delivery. In this review, the authors analyze the practical questions, current controversies, and available evidence regarding psychotropic drug therapy during pregnancy and lactation in bipolar disorder.

Pharmacotherapy for Perinatal Depression

Perinatal depression is associated with serious risks for the mother, baby, and family. When considering treating perinatal depression with a drug indicated for the treatment of depression, the major concerns are whether the drug increases the risks of teratogenicity, pregnancy complications, poor neonatal adaptation, or neurodevelopmental disorders. Although different studies have produced different results, the majority have not shown increases in risk for selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, tricyclic antidepressants, or the noradrenergic/dopaminergic drug bupropion. In this review we will discuss the reproductive safety data for these medications as well as monoamine oxidase inhibitors and benzodiazepines.

Positive screening rates for bipolar disorder in pregnant and postpartum women and associated risk factors

OBJECTIVE

Bipolar disorder affects 2-8% of pregnant and postpartum women; untreated illness is associated with poor outcomes. This study aimed to describe bipolar disorder screening rates in obstetric settings and associated characteristics.

METHOD

Women were recruited during pregnancy through three months postpartum from 14 obstetric clinics in Massachusetts. The Mood Disorder Questionnaire (MDQ) was used to screen for bipolar disorder; a subset previously diagnosed with bipolar was also examined. Differences in characteristics by screening outcome were tested using chi-square and t-tests.

RESULTS

Of 574 participating women, 18.8% screened positive for bipolar disorder. Compared to those with negative, those with positive bipolar screens had 18.5-times the prevalence of positive substance use screens (11.1% vs. 0.6%, p < 0.001) and 3.4-times reported feeling they were not receiving adequate psychiatric help (24.0 vs. 7.0%, p < 0.001). Less than half of those with positive bipolar screens (42.0%) and 61.3% with pre-existing bipolar reported receiving current psychiatric care.

CONCLUSIONS

Almost one in five perinatal women screened positive for bipolar disorder. Positive screenings were associated with comorbid substance use and low treatment rates. This study highlights the importance of screening for bipolar disorder during the perinatal period and the need for systematic approaches to ensure adequate assessment and follow-up.

Psychoactive drug exposure during breastfeeding: a critical need for preclinical behavioral testing

Breastfeeding women are excluded from clinical trials of psychoactive drugs because of ethical concerns. Animal testing, which often is predictive of adverse effects in humans, represents the only avenue available for assessing drug safety for human offspring exposed to drugs during lactation. I determined whether behavioral outcomes for children exposed during breastfeeding to antidepressants, anxiolytics, antipsychotics, anti-seizure medications, analgesics, sedatives, and marijuana can be predicted by rodent studies of offspring exposed to drugs during lactation. Animal data were available for only 10 of 80 CNS-active drugs canvassed. Behavioral deficits in adolescence or adulthood in rats and mice after various drug exposures during lactation included reductions in sexual behavior, increased anxiety, hyperactivity, and impaired learning and memory. Whether similar adverse effects will emerge in adulthood in children exposed to drugs during breastfeeding is unknown. Rodent research has the potential to forecast impairments in breastfed children long before information emerges from post-marketing reports and should be prioritized during preclinical drug evaluation by the FDA for new drugs and for drugs currently prescribed off-label for lactating women.

Anticonvulsants lamotrigine and riluzole disrupt maternal behavior in postpartum female rats

Maternal behavior is a highly motivated and well-organized social behavior. Previous studies have reported that anticonvulsants are frequently used in postpartum bipolar disorder. However, the maternal disruptive effect of the anticonvulsants has not been explored. The purpose of the present study was to examine the effect of anticonvulsants lamotrigine and riluzole on maternal behavior in postpartum female rats. On postpartum Day 3, Sprague-Dawley mother rats were given a single intraperitoneal injection of vehicle, lamotrigine (15, 25, 35 mg/kg), or riluzole (2, 4, 8 mg/kg). Maternal behavior was tested 30 min before and after injection. Animals treated with lamotrigine or riluzole had a longer pup retrieval latency, retrieved fewer pups into the nest, spent less time on nursing pups, as well as on building the disturbed nest, and animals treated with riluzole spent less time on pup licking. Whereas, the drugs in the tested doses did not shorten the total duration of behavior unrelated to maternal behavior. Overall, these data indicate that lamotrigine and riluzole disrupt major components of maternal behavior in postpartum female rats, but do not inhibit the behaviors unrelated to maternal behavior, which indicates that the maternal disruptive effect is not due to nonspecific sedative effect.

Is parity status associated with bipolar disorder clinical features, severity or evolution?

OBJECTIVE

To assess prospectively the association of the number of past pregnancies on the evolution of bipolar disorder (BD).

METHODS

Data were drawn from the 2 waves of the National Epidemiologic Study of Alcohol and Related Conditions (NESARC), a representative sample of the US population of 34,653 participants. All women diagnosed with BD were included. The number of children and BD's characteristics, i.e. BD type, age of onset, hospitalization and suicide attempt, and lifetime psychiatrics comorbidity were assessed at wave 1. Mood episode and BD's characteristics were also assessed at wave 2.

RESULTS

In the sample of 1190 women with BD, 27% had no child, 17% had one, 25% had two 31% had three children or more. Women with at least two children were more likely to have BD I, to report hypomania and suicide attempt during the follow-up than women without child. Parity was not associated with other characteristics of BD, nor with the severity and course of the illness.

LIMITATIONS

Not provide information on pregnancies not ending to a delivery.

CONCLUSION

Parity is associated with a higher incidence of hypomania and suicide attempt during a 3-years follow-up in women with BD.

Mood stabilizers in pregnancy and child developmental outcomes: A systematic review

BACKGROUND

Research suggests that maintaining treatment during pregnancy for women with bipolar affective disorder reduces the risk of relapse. However, one of the key questions for women and clinicians during pregnancy is whether there are implications of exposure to mood stabilizers for longer term child development. Despite these concerns, there are few recent systematic reviews comparing the impact on child developmental outcomes for individual mood-stabilizing agents to inform clinical decisions.

OBJECTIVES

To examine the strengths and limitations of the existing data on child developmental outcomes following prenatal exposure to mood stabilizers and to explore whether there are any differences between agents for detrimental effects on child development.

METHOD

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a rigorous systematic search was carried out of four electronic databases from their respective years of inception to September 2016 to identify studies which examined the effects of mood stabilizers including sodium valproate, carbamazepine, lamotrigine, lithium and second-generation antipsychotics on child developmental outcomes.

RESULTS

We identified 15 studies for critical review. Of these, 10 examined antiepileptic drugs, 2 studied lithium and 3 studied second-generation antipsychotics. The most consistent finding was a dose-response relationship for valproate with higher doses associated with poorer global cognitive abilities compared to other antiepileptic drugs. The limited data available for lithium found no adverse neurodevelopmental outcomes. The limited second-generation antipsychotic studies included a report of a transient early neurodevelopmental delay which resolved by 12 months of age.

CONCLUSION

This review found higher neurodevelopmental risk with valproate. While the existing data on lithium and second-generation antipsychotics are reassuring, these data are both limited and lower quality, indicating that further research is required. The information from this review is relevant for patients and clinicians to influence choice of mood-stabilizing agent in childbearing women. This must be balanced against the known risks associated with untreated bipolar affective disorder.

Pregnancy and bipolar disorder: the risk of recurrence when discontinuing treatment with mood stabilisers: a systematic review

OBJECTIVE

Bipolar disorder in pregnancy may be difficult to treat. The dilemma is whether the women should continue medication throughout pregnancy, and maybe accept a minor risk to harm their unborn child, or discontinue medication and increase the risk of recurrence, which can lead to maternal morbidity, thereby endangering themselves and their foetus. Design and methods In September 2016, three electronic search databases; PubMed, Scopus and PsycInfo, were used searching for clinical trials concerning this question. Eight clinical trials concerning risk of recurrence after discontinuation of medication in pregnancy were included.

RESULTS

There is no consensus concerning the risk of discontinuation of medication during pregnancy among bipolar women. The evidence from the trials included underscore that there seem to be a group of pregnant women who are stable despite they are not receiving mood stabilisers during pregnancy. Besides, there is a group of more severe and more unstable bipolar disorders that seem to benefit of a more close monitoring, support and prophylactic medication during pregnancy and postpartum period to prevent recurrence.

CONCLUSION

For the more stable bipolar women we recommend a well planned and more slowly discontinuation of medication before pregnancy. For the unplanned pregnancies it is important to consider the possibility of a more slowly discontinuation. For the more severe conditions of bipolar disorder, it is important to secure a close monitoring of medication. As the risk of postpartum relapse is high, medication may be started soon after delivery.

Lithium: A classic drug-Frequently discussed, but, sadly, seldom prescribed!

OBJECTIVE

Distinguished authors in the field have repeatedly alerted psychiatrists of the alarming trends in the treatment of bipolar disorders: decline of lithium use, paralleled by the increase of prescribing anticonvulsants and second-generation antipsychotic drugs. Research has been conducted in order to explore the factors that led to this development and to provide arguments for the need to reverse this trend.

METHOD

This paper represents a narrative review of the literature containing retrieved research articles focusing on the efficacy of lithium. The papers included in this overview were published prior to June 2016; additional papers were identified by searching the reference lists of reviewed articles. Taking into account the amount of literature available, no search can be exhaustive; on the other hand, the studies consulted, all of which explore the effectiveness of various compounds, may have their own limitations as well.

RESULTS

The evidence of the effectiveness of lithium in the treatment of acute mania, acute bipolar depression and the prevention of manic and depressive episodes is compelling. Lithium is the most effective augmentation agent in treatment-resistant depression. Its anti-suicidal effects are well established. The neuroprotective effects of lithium have been demonstrated in case-control studies and in population-based research. It has been established that starting lithium early in the course of the disorder reduces the rates of treatment non-response.

CONCLUSIONS

Despite abundant evidence regarding the efficacy of lithium and its effectiveness in the treatment of bipolar disorders, its use is declining at the beginning of the 21st century. It is of paramount importance to keep reminding psychiatrists and educating physicians about the unique properties of lithium and about monitoring patients treated with lithium, since it has been suggested that lithium should once again become the first-line treatment for bipolar disorders.

Pregnancy Outcomes Following In Utero Exposure to Lamotrigine: A Systematic Review and Meta-Analysis

INTRODUCTION

Lamotrigine is used in pregnancy to control epilepsy and mood disorders. The reproductive safety of this widely used drug remains undefined and may represent a significant public health concern.

OBJECTIVE

We aimed to perform a systematic review and meta-analysis of existing knowledge related to malformation rates and maternal-neonatal outcomes after in utero exposure to monotherapy with lamotrigine.

METHODS

Relevant studies were identified through systematic searches conducted in MEDLINE (Ovid), Embase (Ovid), CENTRAL (Ovid), and Web of Science (Thomson Reuters) from database inception to July 2016; no language or date restrictions were applied. All publications of clinically relevant outcomes of pregnancies following in utero exposure to lamotrigine were included in this systematic review and meta-analysis.

RESULTS

A total of 21 studies describing immediate pregnancy outcomes and rates of congenital malformations fulfilled the inclusion criteria. Compared with disease-matched controls (n = 1412, total number of patients) and healthy controls (n = 774,571, total number of patients), in utero exposure to lamotrigine monotherapy was found to be associated with significantly decreased rates of inborn defects (odds ratio [OR] 1.15; 95% confidence interval [CI] 0.62-2.16 and OR 1.25; 95% CI 0.89-1.74, respectively). Rates of miscarriages, stillbirths, preterm deliveries, and small for gestational age (SGA) neonates were not found to have been increased after in-utero exposure to LTG compared to the general population. Similarly, in utero exposure to lamotrigine monotherapy was not found to be associated with increased rates of inborn defects compared with in utero exposure to carbamazepine, and lamotrigine was found to be statistically significantly less teratogenic than valproic acid (n = 12,958 and 10,748; OR 0.84; 95% CI 0.68-1.03 and OR 0.32; 95% CI 0.26-0.39, respectively).

CONCLUSION

No association was found between prenatal lamotrigine monotherapy and increased rates of birth defects and other explored variables related to adverse pregnancy outcomes.

Changes in drug disposition of lithium during pregnancy: a retrospective observational study of patient data from two routine therapeutic drug monitoring services in Norway

OBJECTIVES

Pregnancy may cause changes in drug disposition, dose requirements and clinical response. For lithium, changes in disposition during pregnancy have so far been explored in a single-dose study on 4 participants only. The aim of this study was to determine the effect of pregnancy on serum levels of lithium in a larger patient material in a naturalistic setting.

DESIGN

A retrospective observational study of patient data from 2 routine therapeutic drug monitoring services in Norway, linked to the Medical Birth Registry of Norway.

SETTING

Norway, October 1999 to December 2011.

MEASUREMENTS

Dose-adjusted drug concentrations of lithium during pregnancy were compared with the women's own baseline (non-pregnant) values, using a linear mixed model.

RESULTS

Overall, coupling 196 726 serum concentration measurements from 54 393 women to the national birth registry identified 25 serum lithium concentration analyses obtained from a total of 14 pregnancies in 13 women, and 63 baseline analyses from the same women. Dose-adjusted serum concentrations in the third trimester were significantly lower than baseline (-34%; CI -44% to -23%, p<0.001).

CONCLUSIONS

Pregnancy causes a clinically relevant decline in maternal lithium serum concentrations. In order to maintain stable lithium concentrations during the third trimester of pregnancy, doses generally need to be increased by 50%. Individual variability in decline implies that lithium levels should be even more closely monitored throughout pregnancy and in the puerperium than in non-pregnant women to ensure adequate dosing.

Severe Hypernatremic Dehydration and Lower Limb Gangrene in an Infant Exposed to Lamotrigine, Aripiprazole, and Sertraline in Breast Milk

BACKGROUND

Hypernatremic dehydration is well described in exclusively breastfed neonates, although life-threatening complications are rarely reported.

MATERIALS AND METHODS

The present article describes a case of severe hypernatremic dehydration in a previously healthy term neonate. Other published cases of severe complications of hypernatremic dehydration are discussed.

RESULTS

The exclusively breastfed neonate described had severe hypernatremic dehydration because of inadequate milk intake, with disseminated intravascular coagulation and right lower limb gangrene that required amputation of all five toes and surgical debridement of the metatarsals. The usual etiology of hypernatremic dehydration in this age group is insufficient breast milk intake. Here, the infant's mother was treated for bipolar disorder with lamotrigine 250 mg orally once daily, aripiprazole 15 mg orally once daily, and sertraline 100 mg orally once daily.

CONCLUSIONS

Awareness of these complications should prompt close follow-up of the infant with poor weight gain. The role of maternal medication as a risk factor for hypernatremic dehydration among exclusively breastfed infants needs to be further explored.

[Peripartum management plan for patients with mental illnesses : Strategies to reduce the risk of postpartum relapse]

BACKGROUND

Transition to parenthood is challenging but for women with a history of recurrent psychiatric disorders becoming a mother has a number of additional issues. Women with a history of mood disorders or psychoses are at increased risk for exacerbation in the vulnerable postpartum period and fear the potential risk of medication during pregnancy for the unborn child as much as they fear a relapse. In these difficult situations women and their families seek advice and support from mental health providers and obstetricians.

METHODS AND RESULTS

Based on the treatment of 420 mentally ill women with a desire to have children and pregnancy and prospective documentation of 196 pregnancies over the last 10 years (2006-2016) the authors developed the Bonn concept of peripartum management (BKPM). The plan was designed to reduce the incidence and severity of postpartum relapses in women suffering from psychiatric disorders. Factors to be considered include antenatal and postpartum medication as well as reduction of stress and stimuli, sleep preservation, social support and help from the partner in caring for the baby. Of the 196 women in the BKPM only 4.6 % (n = 9) experienced a severe postpartum relapse with hospitalization. Additionally, the informed consent discussion with patient and partner as part of the peripartum management plan showed positive effects on how women and their families experienced autonomy and safety during pregnancy and postpartum.

DISCUSSION

Careful planning and monitoring with a structured perinatal management plan can reduce the risk of relapse in the perinatal period and thus support women with a history of mental disorder in the transition to motherhood. Therefore, the management concept employed in Bonn contributes to the major goal of current peripartum psychiatric care in developing effective prevention strategies for women at high risk.
