Paroxetine and congenital malformations: Meta-Analysis and consideration of potential confounding factors

Exploring genetic causal relationship between antidepressants use and congenital malformations

Existing studies have demonstrated that the use of antidepressants is associated with congenital malformations; however, the conclusions are inconsistent, and the potential causal relationship remains unclear. Based on large-scale genetic data, we conducted a two-sample Mendelian randomization (MR) study. The exposure datasets included the use of antidepressants, responses to selective serotonin reuptake inhibitors (SSRIs), and the use of four SSRIs-related antidepressants: fluoxetine, citalopram, paroxetine, and sertraline. The outcome datasets encompassed congenital malformations across 12 major organ systems, as well as overall congenital malformations. All datasets were of European ancestry. We employed inverse variance weighting (IVW), MR-Egger, and weighted median methods as our MR analytical approaches. Additionally, the robustness of the MR results was evaluated through a series of sensitivity analyses. After Bonferroni multiple comparisons, MR results did not reveal a significant association between the use of all antidepressants and any congenital malformations. However, IVW provided a suggestive positive association between antidepressants use and congenital digestive malformations (OR = 1.28, 95 % CI = 1.01-1.62, P = 0.039), as well as between SSRIs response and respiratory system malformations (OR = 1.21, 95 % CI = 1.02-1.44, P = 0.033), and fluoxetine use and nervous system malformations (P = 0.026). This study did not find evidence of an association between the use of citalopram, paroxetine, or sertraline and any congenital malformations. Our study provides evidence of a causal association between exposure to antidepressants and certain specific congenital malformations. However, further in-depth research is needed to confirm this association and explore the underlying biological mechanisms.

Variation in clinical practice guideline recommendations for medication use in pregnancy in Australia: A systematic review

BACKGROUND

Medication use in pregnancy is common; however, it is unknown if clinical practice guideline (CPG) prescribing recommendations referred to in Australia at the state, national and international level are consistent.

AIMS

This systematic review aimed to: (1) identify sources of CPGs that inform prescribing during pregnancy in Australia; (2) assess CPG quality; and (3) evaluate variation within CPG recommendations for medication use in three common conditions in pregnancy: prophylactic antibiotics following premature rupture of membranes (PROM) at term, antidepressants in pregnancy and metformin in gestational diabetes mellitus (GDM).

MATERIALS AND METHODS

A literature search was conducted across PubMed, Scopus and EMBASE databases. Grey literature was identified through publicly available Australian policy statements. Prescribing recommendations for prophylactic antibiotics following PROM at term, antidepressants in pregnancy and metformin in GDM, were compared at the state, national and international levels. CPG quality was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument.

RESULTS

We identified 39 CPG sources that inform prescribing during pregnancy in Australia. CPG quality varied between resources. There was minor variation in recommendations for antibiotic prophylaxis in PROM at term. Recommendations regarding metformin use in GDM were also variable, with CPGs either recommending its use as a first-line agent when lifestyle modifications are not effective or when insulin therapy is not practicable. Recommendations for antidepressant use were consistent across CPGs analysed.

CONCLUSION

Multiple CPGs exist to inform prescribing during pregnancy in Australia, with variation present within CPG quality and recommendations. These findings offer insight into potential sources of variation in maternal and neonatal health outcomes.

Maternal exposure to SSRIs or SNRIs and the risk of congenital abnormalities in offspring: A systematic review and meta-analysis

BACKGROUND

The association of maternal exposure to selective serotonin reuptake inhibitors (SSRIs) or serotonin and norepinephrine reuptake inhibitors (SNRIs) with the risk of system-specific congenital malformations in offspring remains unclear. We conducted a meta-analysis to examine this association and the risk difference between these two types of inhibitors.

METHODS

A literature search was performed from January 2000 to May 2023 using PubMed and Web of Science databases. Cohort and case-control studies that assess the association of maternal exposure to SSRIs or SNRIs with the risk of congenital abnormalities were eligible for the study.

RESULTS

Twenty-one cohort studies and seven case-control studies were included in the meta-analysis. Compared to non-exposure, maternal exposure to SNRIs is associated with a higher risk of congenital cardiovascular abnormalities (pooled OR: 1.64 with 95% CI: 1.36, 1.97), anomalies of the kidney and urinary tract (pooled OR: 1.63 with 95% CI: 1.21, 2.20), malformations of nervous system (pooled OR: 2.28 with 95% CI: 1.50, 3.45), anomalies of digestive system (pooled OR: 2.05 with 95% CI: 1.60, 2.64) and abdominal birth defects (pooled OR: 2.91 with 95%CI: 1.98, 4.28), while maternal exposure to SSRIs is associated with a higher risk of congenital cardiovascular abnormalities (pooled OR: 1.25 with 95%CI: 1.20, 1.30), anomalies of the kidney and urinary tract (pooled OR: 1.14 with 95%CI: 1.02, 1.27), anomalies of digestive system (pooled OR: 1.11 with 95%CI: 1.01, 1.21), abdominal birth defects (pooled OR: 1.33 with 95%CI: 1.16, 1.53) and musculoskeletal malformations (pooled OR: 1.44 with 95%CI: 1.32, 1.56).

CONCLUSIONS

SSRIs and SNRIs have various teratogenic risks. Clinicians must consider risk-benefit ratios and patient history when prescribing medicines.

Prevalence and associated factors of structural congenital anomalies in resource limited setting, 2023: a systematic review and meta-analysis

Background

Several studies have been conducted on structural congenital anomalies (CA). However, there is a paucity of studies that provide a comprehensive review of structural anomalies. We aimed to verify the available research articles to pool the possible risk factors of structural CA in resource-limited settings.

Setting

The research articles were genuinely searched using PubMed, Scopus, Cochrane Library, Web of Science, free Google database search engines, Google Scholar, and ScienceDirect databases. Published studies were searched and screened for inclusion in the final analysis, and studies without sound methodologies and review and meta-analysis were not included in the analysis.

Participants

This review analyzed data from 95,755 women who gave birth as reported by primary studies. Ten articles were included in this systematic review and meta-analysis. The articles that had incomplete information and case reports were excluded from the study.

Results

The overall pooled effect estimate (EI) of structural CA was 5.50 (4.88-6.12) per 100 births. In this systematic review and meta-analysis, maternal illness EI with odds ratio (OR) = 4.93 (95% CI: 1.02-8.85), unidentified drug use with OR = 2.83 (95% CI: 1.19-4.46), birth weight with OR = 4.20 (95% CI: 2.12-6.28), chewing chat with OR = 3.73 (95% CI: 1.20-6.30), chemical exposure with OR = 4.27 (95% CI: 1.19-8.44), and taking folic acid tablet during pregnancy with OR = 6.01 (95% CI: 2.87-14.89) were statistically significant in this meta-regression.

Conclusions

The overall pooled effect estimate of structural CA in a resource-limited setting was high compared to that in countries with better resources. Maternal illness, unidentified drug use, birth weight, chewing chat, chemical exposure, and never using folic acid were found to be statistically significant variables in the meta-regression. Preconception care and adequate intake of folic acid before and during early pregnancy should be advised.

On the Meta-regression maternal illness, unidentified drug use, birth weight, chewing chat, chemical exposure and never using folic acid were found to be statistically significant variables Preconception care and adequate intake of folic acid before and during early pregnancy should be advised.

Consensus Panel Recommendations for the Pharmacological Management of Pregnant Women with Depressive Disorders

INTRODUCTION

The initiative of a consensus on the topic of antidepressant and anxiolytic drug use in pregnancy is developing in an area of clinical uncertainty. Although many studies have been published in recent years, there is still a paucity of authoritative evidence-based indications useful for guiding the prescription of these drugs during pregnancy, and the data from the literature are complex and require expert judgment to draw clear conclusions.

METHODS

For the elaboration of the consensus, we have involved the scientific societies of the sector, namely, the Italian Society of Toxicology, the Italian Society of Neuropsychopharmacology, the Italian Society of Psychiatry, the Italian Society of Obstetrics and Gynecology, the Italian Society of Drug Addiction and the Italian Society of Addiction Pathology. An interdisciplinary team of experts from different medical specialties (toxicologists, pharmacologists, psychiatrists, gynecologists, neonatologists) was first established to identify the needs underlying the consensus. The team, in its definitive structure, includes all the representatives of the aforementioned scientific societies; the task of the team was the evaluation of the most accredited international literature as well as using the methodology of the "Nominal Group Technique" with the help of a systematic review of the literature and with various discussion meetings, to arrive at the drafting and final approval of the document.

RESULTS

The following five areas of investigation were identified: (1) The importance of management of anxiety and depressive disorders in pregnancy, identifying the risks associated with untreated maternal depression in pregnancy. (2) The assessment of the overall risk of malformations with the antidepressant and anxiolytic drugs used in pregnancy. (3) The evaluation of neonatal adaptation disorders in the offspring of pregnant antidepressant/anxiolytic-treated women. (4) The long-term outcome of infants' cognitive development or behavior after in utero exposure to antidepressant/anxiolytic medicines. (5) The evaluation of pharmacological treatment of opioid-abusing pregnant women with depressive disorders.

CONCLUSIONS

Considering the state of the art, it is therefore necessary in the first instance to frame the issue of pharmacological choices in pregnant women who need treatment with antidepressant and anxiolytic drugs on the basis of data currently available in the literature. Particular attention must be paid to the evaluation of the risk/benefit ratio, understood both in terms of therapeutic benefit with respect to the potential risks of the treatment on the pregnancy and on the fetal outcome, and of the comparative risk between the treatment and the absence of treatment; in the choice prescription, the specialist needs to be aware of both the potential risks of pharmacological treatment and the equally important risks of an untreated or undertreated disorder.

Reproductive Safety of Lurasidone and Quetiapine: Update from the National Pregnancy Registry for Psychiatric Medications

Background: Second-generation antipsychotics (SGAs), also called atypical antipsychotics, are common therapies for women with a spectrum of psychiatric disorders. No systematically ascertained human reproductive safety data are available for lurasidone, and prospective data for quetiapine are limited, making decisions regarding use of these medications during pregnancy complicated. Materials and Methods: The National Pregnancy Registry for Psychiatric Medications is a prospective cohort study designed to collect reproductive safety data relative to SGAs. Pregnant women aged 18-45 years, with psychiatric illness and prenatal psychotropic medication exposure completed three phone interviews during pregnancy and the postpartum period. Cases of presumed malformations are abstracted from medical records for adjudication by a teratologist blinded to medication exposure. Results: Of 2,293 women enrolled at the time of analysis, 134 in the lurasidone group, 264 in the quetiapine group, and 886 controls completed the postpartum interview and were therefore eligible for inclusion. Dropped or lost-to-follow-up participants (13%) and those currently pregnant were excluded. Participants were predominantly White, college-educated, and married (lurasidone = 88.1%, 76.9%, 77.6%; quetiapine = 89.8%, 71.2%, 75.0%; controls = 92.7%, 86.7%, 89.1%). Absolute risks of major malformations were 2.19% (lurasidone), 1.85% (quetiapine), and 1.77% (controls). Odds ratios comparing lurasidone and quetiapine with controls were 1.24 (95% confidence interval [CI] = 0.36-4.32) and 1.04 (95% CI = 0.38-2.85), respectively. Conclusions: No specific patterns of malformations were observed in infants exposed to the medications of interest. Lurasidone and quetiapine did not appear to be major teratogens, but further information is needed to refine risk estimates. Food and Drug Administration guidance underscores the importance of pregnancy registries. Clinical trial number: NCT01246765.

Development of the Placenta and Brain Are Affected by Selective Serotonin Reuptake Inhibitor Exposure During Critical Periods

Selective serotonin reuptake inhibitors (SSRIs) are usually prescribed to treat major depression and anxiety disorders. Fetal brain development exhibits dependency on serotonin (5-hydroxytryptamine, 5-HT) from maternal, placental, and fetal brain sources. At very early fetal stages, fetal serotonin is provided by maternal and placental sources. However, in later fetal stages, brain sources are indispensable for the appropriate development of neural circuitry and the rise of emergent functions implied in behavior acquisition. Thus, susceptible serotonin-related critical periods are recognized, involving the early maternal and placental 5-HT synthesis and the later endogenous 5-HT synthesis in the fetal brain. Acute and chronic exposure to SSRIs during these critical periods may result in short- and long-term placental and brain dysfunctions affecting intrauterine and postnatal life. Maternal and fetal cells express serotonin receptors which make them susceptible to changes in serotonin levels influenced by SSRIs. SSRIs block the serotonin transporter (SERT), which is required for 5-HT reuptake from the synaptic cleft into the presynaptic neuron. Chronic SSRI administration leads to pre- and postsynaptic 5-HT receptor rearrangement. In this review, we focus on the effects of SSRIs administered during critical periods upon placentation and brain development to be considered in evaluating the risk-safety balance in the clinical use of SSRIs.

Selective Serotonin Reuptake Inhibitors (SSRIs) in Pregnancy: An Updated Review on Risks to Mother, Fetus, and Child

PURPOSE OF REVIEW

To provide an updated summary and appraisal of work from 2019 to 2022 examining risks of selective serotonin reuptake inhibitor (SSRI) use in pregnancy.

RECENT FINDINGS

Perinatal SSRI exposure does not increase risk of major malformations or gestational diabetes after accounting for underlying maternal illness. SSRIs are associated with small increase in risk of pre-eclampsia, postpartum hemorrhage, preterm delivery, persistent pulmonary hypertension of the newborn, and neonatal intensive care unit admissions, though absolute risk of these outcomes is low. While data suggests no increased risk of neurodevelopmental disorders in offspring, mixed evidence indicates increased risk of adverse cognitive outcomes and affective disorders. Recent evidence suggest low absolute risk of clinically relevant negative outcomes with perinatal SSRI exposure when compared to untreated perinatal depression. However, study design and ability to control for confounding remains an ongoing research challenge, highlighting need for ongoing rigorous study design and analysis.

A Systematic Review and Meta-Analysis Considering the Risk for Congenital Heart Defects of Antidepressant Classes and Individual Antidepressants

INTRODUCTION

Antidepressant use during the first trimester is reported in 4-8% of pregnancies. The use of some selective serotonin reuptake inhibitors during the first trimester has been identified as increasing the odds for congenital heart defects; however, little is known about the safety of non-selective serotonin reuptake inhibitor antidepressants.

OBJECTIVE

The objective of this study was to assess the odds of congenital heart defects associated with the use of antidepressants during the first trimester of pregnancy, and to update the literature as newer studies have been published since the latest systematic literature review and meta-analysis.

METHODS

PubMed and Embase were searched till 3 June, 2020. Study quality was assessed, and study details were extracted. Meta-analyses were performed using RevMan 5.4, which assessed: (1) any antidepressant usage; (2) classes of antidepressants; and (3) individual antidepressants.

RESULTS

Twenty studies were identified, encompassing 5,337,223 pregnancies. The odds ratio for maternal use of any antidepressant during the first trimester of pregnancy and the presence of congenital heart defects from the random effects meta-analysis was 1.28 (95% confidence interval [CI] 1.17-1.41). Significant odds ratios of 1.69 (95% CI 1.37-2.10) and 1.25 (95% CI 1.15-1.37) were reported for serotonin norepinephrine reuptake inhibitors and selective serotonin reuptake inhibitors, respectively. A non-statistically significant odds ratio of 1.02 (95% CI 0.82-1.25) was reported for the tricyclic antidepressants. Analyses of individual SSRIs produced significant odds ratios of 1.57 (95% CI 1.25-1.97), 1.36 (95% CI 1.08-1.72), and 1.29 (95% CI 1.14-1.45) for paroxetine, fluoxetine, and sertraline, respectively. The norepinephrine-dopamine-reuptake inhibitor bupropion also produced a significant odds ratio of 1.23 (95% CI 1.01-1.49).

CONCLUSIONS

The selective serotonin reuptake inhibitor and serotonin norepinephrine reuptake inhibitor classes of antidepressants pose a greater risk for causing congenital heart defects than the tricyclic antidepressants. However, this risk for individual antidepressants within each class varies, and information regarding some antidepressants is still lacking.

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.

The evolution of fetal echocardiography before and during COVID-19

The World Health Organization declared the novel coronavirus, or COVID-19, a pandemic in March 2020. Given the severity of COVID-19, appropriate use criteria have been implemented for fetal echocardiography. Screening low risk pregnancies for critical congenital heart disease has typically been a shared responsibility by pediatric cardiologists, obstetricians, and maternal fetal medicine (MFM). Currently, many of the fetal echocardiograms for low risk pregnancies for critical congenital heart disease have been deferred or cancelled with the emphasis on suspected abnormalities by MFMs and obstetricians. In this review, we discuss the literature that has been the basis of screening of low risk pregnancies by pediatric cardiologists. A new approach to more widespread usage of fetal tele-echocardiography may play a large part during COVID-19 and may continue after the pandemic.

•

Appropriate use criteria for fetal echocardiography have been implemented during the COVID-19 pandemic.

•

Pediatric cardiologists have deferred fetal echo for low risk pregnancies, emphasizing those with suspected abnormalities.

•

Current fetal echo guidelines highlight maternal, familial, and fetal risk factors, and the associated incidence of CHD.

•

Fetal tele-echocardiography and telehealth consultation may enhance the ability to provide care during and beyond COVID-19.

Risk-benefit balance assessment of SSRI antidepressant use during pregnancy and lactation based on best available evidence - an update

Introduction: Depression affects 300 million individuals worldwide. While selective serotonin reuptake inhibitors (SSRI) are one of the first-line pharmacological treatments of major depression in the general population, there is still uncertainty regarding their potential benefits and risks during pregnancy. Areas covered: Outcomes requisite for a proper risk/benefit assessment of SSRI in pregnancy and lactation were considered: (a) potential risks associated with untreated depression, (b) effectiveness of different treatment options of depression, (c) potential risks associated with SSRI. Expert opinion: Despite the growing amount of literature on SSRI use during pregnancy, no new trials assessing the benefits of SSRIs on maternal depression were found. In the light of new data regarding the potential risks, depressed SSRI-treated pregnant women and their children seem at increased risk for several complications (mostly of small absolute risk). The interpretation of these findings remains quite similar to our previous review as the available methodology does not allow to disentangle the potential effect of SSRIs from those of the disease itself or/and of its unmeasured associated risk factors. Thus, in pregnant or lactating women who require a pharmacological treatment, SSRIs can still be considered as appropriate when effective as the abundant data support their relative safety.

SSRIs and SNRIs (SRI) in Pregnancy: Effects on the Course of Pregnancy and the Offspring: How Far Are We from Having All the Answers?

Serotonin has important roles in the development of the brain and other organs. Manipulations of synaptic serotonin by drugs such as serotonin reuptake inhibitors (SRI) or serotonin norepinephrine reuptake inhibitors (SNRI) might alter their development and function. Of interest, most studies on the outcome of prenatal exposure to SRI in human have not found significant embryonic or fetal damage, except for a possible, slight increase in cardiac malformations. In up to a third of newborns exposed to SRI, exposure may induce transient neonatal behavioral changes (poor neonatal adaptation) and increased rate of persistent pulmonary hypertension. Prenatal SRI may also cause slight motor delay and language impairment but these are transient. The data on the possible association of prenatal SRIs with autism spectrum disorder (ASD) are inconsistent, and seem to be related to pre-pregnancy treatment or to maternal depression. Prenatal SRIs also appear to affect the hypothalamic hypophyseal adrenal (HPA) axis inducing epigenetic changes, but the long-term consequences of these effects on humans are as yet unknown. SRIs are metabolized in the liver by several cytochrome P450 (CYP) enzymes. Faster metabolism of most SRIs in late pregnancy leads to lower maternal concentrations, and thus potentially to decreased efficacy which is more prominent in women that are rapid metabolizers. Studies suggest that the serotonin transporter SLC6A4 promoter is associated with adverse neonatal outcomes after SRI exposure. Since maternal depression may adversely affect the child's development, one has to consider the risk of SRI discontinuation on the fetus and the child. As with any drug treatment in pregnancy, the benefits to the mother should be considered versus the possible hazards to the developing embryo/fetus.

Perinatal exposure to the SSRI paroxetine alters the methylome landscape of the developing dentate gyrus

Evidence in humans and rodents suggests that perinatal exposure to selective serotonin reuptake inhibitor (SSRI) antidepressants can have serious long-term consequences in offspring exposed in utero or infancy via breast milk. In spite of this, there is limited knowledge of how perinatal SSRI exposure impacts brain development and adult behaviour. Children exposed to SSRIs in utero exhibit increased internalizing behaviour and abnormal social behaviour between the ages of 3 and 6, and increased risk of depression in adolescence; however, the neurobiological changes underlying this behaviour are poorly understood. In rodents, perinatal SSRI exposure perturbs hippocampal gene expression and alters adult emotional behaviour (including increased depression-like behaviour). The present study demonstrates that perinatal exposure to the SSRI paroxetine leads to DNA hypomethylation and reduces DNA methyltransferase 3a (Dnmt3a) mRNA expression in the hippocampus during the second and third weeks of life. Next-generation sequencing identified numerous differentially methylated genomic regions, including altered methylation and transcription of several dendritogenesis-related genes. We then tested the hypothesis that transiently decreasing Dnmt3a expression in the early postnatal hippocampus would mimic the behavioural effects of perinatal SSRI exposure. We found that siRNA-mediated knockdown of Dnmt3a in the dentate gyrus during the second to third week of life produced greater depression-like behaviour in adult female (but not male) offspring, akin to the behavioural consequences of perinatal SSRI exposure. Overall, these data suggest that perinatal SSRI exposure may increase depression-like behaviours, at least in part, through reduced Dnmt3a expression in the developing hippocampus.

Selective serotonin reuptake inhibitor use during early pregnancy and congenital malformations: a systematic review and meta-analysis of cohort studies of more than 9 million births

BACKGROUND

In 2005, the FDA cautioned that exposure to paroxetine, a selective serotonin reuptake inhibitor (SSRI), during the first trimester of pregnancy may increase the risk of cardiac malformations. Since then, the association between maternal use of SSRIs during pregnancy and congenital malformations in infants has been the subject of much discussion and controversy. The aim of this study is to systematically review the associations between SSRIs use during early pregnancy and the risk of congenital malformations, with particular attention to the potential confounding by indication.

METHODS

The study protocol was registered with PROSPERO (CRD42018088358). Cohort studies on congenital malformations in infants born to mothers with first-trimester exposure to SSRIs were identified via PubMed, Embase, Web of Science, and the Cochrane Library databases through 17 January 2018. Random-effects models were used to calculate summary relative risks (RRs).

RESULTS

Twenty-nine cohort studies including 9,085,954 births were identified. Overall, use of SSRIs was associated with an increased risk of overall major congenital anomalies (MCAs, RR 1.11, 95% CI 1.03 to 1.19) and congenital heart defects (CHD, RR 1.24, 95% CI 1.11 to 1.37). No significantly increased risk was observed when restricted to women with a psychiatric diagnosis (MCAs, RR 1.04, 95% CI 0.95 to 1.13; CHD, RR 1.06, 95% CI 0.90 to 1.26). Similar significant associations were observed using maternal citalopram exposure (MCAs, RR 1.20, 95% CI 1.09 to 1.31; CHD, RR 1.24, 95% CI 1.02 to 1.51), fluoxetine (MCAs, RR 1.17, 95% CI 1.07 to 1.28; CHD, 1.30, 95% CI 1.12 to 1.53), and paroxetine (MCAs, RR 1.18, 95% CI 1.05 to 1.32; CHD, RR 1.17, 95% CI 0.97 to 1.41) and analyses restricted to using women with a psychiatric diagnosis were not statistically significant. Sertraline was associated with septal defects (RR 2.69, 95% CI 1.76 to 4.10), atrial septal defects (RR 2.07, 95% CI 1.26 to 3.39), and respiratory system defects (RR 2.65, 95% CI 1.32 to 5.32).

CONCLUSIONS

The evidence suggests a generally small risk of congenital malformations and argues against a substantial teratogenic effect of SSRIs. Caution is advisable in making decisions about whether to continue or stop treatment with SSRIs during pregnancy.

Perinatal anxiety: approach to diagnosis and management in the obstetric setting

Anxiety is common in women during the perinatal period, manifests with various symptoms and severity, and is associated with significant maternal morbidity and adverse obstetric and neonatal outcomes. Given the intimate relationship and frequency of contact, the obstetric provider is positioned optimally to create a therapeutic alliance and to treat perinatal anxiety. Time constraints, absence of randomized controlled trials, mixed quality of data, and concern for potential adverse reproductive outcomes all limit the clinician's ability to initiate informed risk-benefit discussions. Clear understanding of the role of the obstetric provider in the identification, stabilization, and initiation of medication and/or referral to psychotherapy for women with perinatal anxiety disorders is critical to maternal and neonatal wellbeing. Informed by our clinical practice as perinatal psychiatric providers, we have provided a concise summary of current research on the approach to the treatment of perinatal anxiety disorders in the obstetric setting that includes psychotherapy and supportive interventions, primary and adjuvant psychiatric medication, and general prescribing pearls. Medications that we examined include antidepressants, benzodiazepines, sedative-hypnotics, antihistamines, quetiapine, buspirone, propranolol, and melatonin. Further research into management of perinatal anxiety, particularly psychopharmacologic management, is warranted.

Exposure to selective serotonin reuptake inhibitors in utero and early elementary school outcomes

OBJECTIVE

Data on special education in offspring exposed to selective serotonin reuptake inhibitors (SSRIs) in utero are lacking. We examined associations of in utero SSRI exposure with special education needs and delayed elementary school start.

METHODS

A population-based case-cohort study using Danish nationwide birth and prescription registry data from 2005 to 2008. Follow-up ends during 2011-2015 to capture special education needs during and delayed entry to the first elementary school year. Cases were in utero SSRI-exposed offspring. Cohort-controls were SSRI-unexposed offspring of mothers previously on SSRIs. We reported odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for relevant potential confounders.

RESULTS

Of 117 475 first-incident non-multiple pregnancy births, 3314 were SSRI-exposed, and 3536 were unexposed. Among SSRI-exposed offspring, 3.2% (n = 98) had special school needs vs. 2.4% (n = 77) in unexposed offspring, P-value=0.048. Correspondingly, 12.3% (n = 383) among SSRI-exposed children had delayed school entry vs. 9.4% (n = 308) in unexposed offspring, P-value < 0.001. Adjusted OR for the association with special school needs was 1.12 (95% CI 0.82-1.55; P-value = 0.48) and 1.38 (95% CI 0.90-2.13; P-value = 0.14) for exposure in all three trimesters. The corresponding adjusted ORs for delayed school entry were 1.17 (95% CI 0.99-1.38; P-value = 0.073) and 1.40 (95% CI 1.11-1.76; P-value = 0.004).

CONCLUSION

In utero SSRI exposure in all three trimesters was associated with delayed elementary school start but not special education needs.

Cardiac Outcomes After Perinatal Sertraline Exposure in Mice

Selective serotonin reuptake inhibitors are prescribed to 6%-10% of pregnant women in the United States. Using an intrauterine plus neonatal exposure model to represent exposure throughout human pregnancy, we hypothesized sertraline exposure would impact intracardiac serotonin signaling and lead to small left heart syndrome in the absence of maternal psychopathology. C57BL/6 adult female mice received sertraline (5 mg·kg·d IP) or saline throughout pregnancy to time of delivery. Pups maintained exposure on postnatal days 1-14 to encompass the developmental window analogous to human gestation. Sertraline-exposed mice had increased cardiac hydroxyproline content, decreased 5-HT2B receptor mRNA levels, and increased 5-HT2A receptor and serotonin transporter mRNA levels on postnatal day 21 (P < 0.05). These changes were associated with diminished exercise capacity at 6 weeks (P < 0.05) and decreased adult shortening fraction and stroke volume at 5 months. Isolated cardiomyocytes from neonatal sertraline-exposed mice had significantly decreased proliferation, cross-sectional area, and phosphorylation of Akt (P < 0.05 vs. neonatal control mice). Perinatal sertraline exposure alters neonatal cardiac development and produces long-standing changes in adult cardiac function and exercise capacity. Further studies are needed to assess whether similar findings are present in the growing population that has been exposed to selective serotonin reuptake inhibitors during development.

Selective serotonin reuptake inhibitor use in pregnant women; pharmacogenetics, drug-drug interactions and adverse effects

INTRODUCTION

Possible negative effects of selective serotonin reuptake inhibitors (SSRIs) in pregnancy relate to congenital anomalies, negative perinatal events and neurodevelopmental outcome. Many studies are confounded by the underlying maternal disease and by pharmacogenetic and pharmacokinetic differences of these drugs. Areas covered: The possible interactions of SSRIs and serotonin and norepinephrine reuptake inhibitors with other drugs and the known effects of SSRIs on congenital anomalies, perinatal and neurodevelopmental outcome. Expert opinion: SSRIs should be given with caution when combined with other drugs that are metabolized by cytochrome P450 enzymes. SSRIs apparently increase the rate of severe cardiac malformations, induce neonatal adaptation problems in up to 30% of the offspring, increase the rate of persistent pulmonary hypertension of the newborn and possibly slightly increase the rate of prematurity and low birth weight. Most neurodevelopmental follow up studies did not find significant cognitive impairments except some transient gross motor delay, slight impairment of language abilities and possibly behavioral changes. The literature on the possible association of SSRIs with autism spectrum disorder is inconsistent; if an association exists, it is apparently throughout pregnancy. The risk associated with treatment discontinuation seems to outweigh the risk of treatment, as severe maternal depression may negatively affect the child's development. If needed, treatment should continue in pregnancy with the minimal effective dose.

Characteristics of patients seen by a community perinatal mental health service

Aims and Method

Recent guidelines on perinatal mental health highlight the need to predict, detect and prevent mental illness in childbearing women, but there are a limited number of studies in this field. This study describes the characteristics of 277 service users newly referred to a specialist community perinatal mental health service over 1 year, and discusses the implications for effective management of mental illness related to childbearing.

Results

The most common diagnosis was affective disorder (51%), of which 8% had bipolar affective disorder. Almost three in five women had previous non-pregnancy-related psychiatric contact and a fourth had previous ante/postnatal psychiatric contact. More than half were on medication at conception, most commonly antidepressants (43%).

Clinical Implications

This study highlights the opportunities for identifying women at high risk of postnatal mental illness and the need for adequate pregnancy planning advice for women taking psychotropic medication.

Drug-induced cardiac abnormalities in premature infants and neonates

The Cardiac Safety Research Consortium (CSRC) is a transparent, public-private partnership that was established in 2005 as a Critical Path Program and formalized in 2006 under a Memorandum of Understanding between the United States Food and Drug Administration and Duke University. Our continuing goal is to advance paradigms for more efficient regulatory science related to the cardiovascular safety of new therapeutics, both in the United States and globally, particularly where such safety questions add burden to innovative research and development. This White Paper provides a summary of discussions by a cardiovascular committee cosponsored by the CSRC and the US Food and Drug Administration (FDA) that initially met in December 2014, and periodically convened at FDA's White Oak headquarters from March 2015 to September 2016. The committee focused on the lack of information concerning the cardiac effects of medications in the premature infant and neonate population compared with that of the older pediatric and adult populations. Key objectives of this paper are as follows: Provide an overview of human developmental cardiac electrophysiology, as well as the electrophysiology of premature infants and neonates; summarize all published juvenile animal models relevant to drug-induced cardiac toxicity; provide a consolidated source for all reported drug-induced cardiac toxicities by therapeutic area as a resource for neonatologists; present drugs that have a known cardiac effect in an adult population, but no reported toxicity in the premature infant and neonate populations; and summarize what is not currently known about drug-induced cardiac toxicity in premature infants and neonates, and what could be done to address this lack of knowledge. This paper presents the views of the authors and should not be construed to represent the views or policies of the FDA or Health Canada.

Sertraline use in the first trimester and risk of congenital anomalies: a systemic review and meta-analysis of cohort studies

AIM

To perform a meta-analysis of available cohort studies on the association between sertraline use by pregnant women in the first trimester and the findings of congenital anomalies in infants.

METHODS

A comprehensive search of articles published from the index date up to 31st December 2015 investigating the aforementioned associations was conducted on PubMed and Web of Science. Mesh headings used included the terms "serotonin reuptake inhibitor," "sertraline," "congenital anomalies" and "obstetrical outcome."

RESULTS

Twelve cohort studies that involved 6 468 241 pregnant women were identified. We summarized odds ratios (ORs) and 95% confidence intervals (CIs) of congenital anomalies using the random-effects model. Pregnant women who used sertraline in the first trimester had a statistically significant increased risk of infant cardiovascular-related malformations (OR = 1.36; 95% CI = 1.06-1.74; I2  = 64.4%; n = 12) as well as atrial and/or ventricular septal defects (OR = 1.36, 95% CI = 1.06-1.76; I2  = 62.2%; n = 8). Additionally, positive but nonsignificant associations between sertraline use and congenital anomalies of the nervous system (OR = 1.39; 95% CI = 0.83-2.32; I2  = 0%; n = 5), digestive system (OR = 1.23; 95% CI = 0.76-1.98; I2  = 0%; n = 5), eye, ear, face and neck (OR = 1.08; 95% CI = 0.33-3.55; I2  = 32.1%; n = 3), urogenital system (OR = 1.03; 95% CI = 0.73-1.46; I2  = 0%; n = 5), and musculoskeletal system (OR = 0.97; 95% CI = 0.69-1.36; I2  = 0%; n = 5) were observed.

CONCLUSION

This meta-analysis suggested that the use of sertraline use by pregnant women in the first trimester had an increased risk of cardiovascular-related malformations as well as atrial and/or ventricular septal defects in infants. Meanwhile, nonsignificant associations between sertraline use and other congenital anomalies were found. More cohort studies are warranted to provide detailed results of other congenital anomalies.

Effects of prenatal yoga on women's stress and immune function across pregnancy: A randomized controlled trial

OBJECTIVE

The effects of prenatal yoga on biological indicators have not been widely studied. Thus, we compared changes in stress and immunity salivary biomarkers from 16 to 36 weeks' gestation between women receiving prenatal yoga and those receiving routine prenatal care.

DESIGN

For this longitudinal, prospective, randomized controlled trial, we recruited 94 healthy pregnant women at 16 weeks' gestation through convenience sampling from a prenatal clinic in Taipei. Participants were randomly assigned to intervention (n=48) or control (n=46) groups using Clinstat block randomization.

INTERVENTION

The 20-week intervention comprised two weekly 70-min yoga sessions led by a midwife certified as a yoga instructor; the control group received only routine prenatal care.

MAIN OUTCOME MEASURES

In both groups, participants' salivary cortisol and immunoglobulin A levels were collected before and after yoga every 4 weeks from 16 to 36 weeks' gestation.

RESULTS

The intervention group had lower salivary cortisol (p<0.001) and higher immunoglobulin A (p<0.001) levels immediately after yoga than the control group. Specifically, the intervention group had significantly higher long-term salivary immunoglobulin A levels than the control group (p=0.018), and infants born to women in the intervention group weighed more than those born to the control group (p<0.001).

CONCLUSION

Prenatal yoga significantly reduced pregnant women's stress and enhanced their immune function. Clinicians should learn the mechanisms of yoga and its effects on pregnant women. Our findings can guide clinicians to help pregnant women alleviate their stress and enhance their immune function.

Use of selective serotonin-reuptake inhibitors in the first trimester and risk of cardiovascular-related malformations: a meta-analysis of cohort studies

The relationship between selective serotonin-reuptake inhibitors (SSRIs) use during first trimester and cardiovascular-related malformations of infants is still uncertain. Therefore, we conducted this systematic review and meta-analysis to assess the aforementioned association. A systematic literature review identified studies for cohort studies about SSRIs use and cardiovascular-related malformations in PubMed and Web of Science. We summarized relative risk (RRs) and 95% confidence intervals (CIs) of cardiovascular-related malformations using random-effects model, and heterogeneity and publication-bias analyses were conducted. Eighteen studies met the inclusion criteria. Pregnant women who were exposed to SSRIs at any point during the first trimester had a statistically significant increased risk of infant cardiovascular-related malformations (RR = 1.26, 95%CI = 1.13-1.39), with moderate heterogeneity (I2 = 53.6). The corresponding RR of atrial septal defects (ASD), ventricular septal defects (VSD), ASD and/or VSD was 2.06 (95%CI = 1.40-3.03, I2 = 57.8), 1.15 (95%CI = 0.97-1.36; I2 = 30.3), and 1.27 (95%CI = 1.14-1.42; I2 = 40.0), respectively. No evidence of publication bias and significant heterogeneity between subgroups was detected by meta-regression analyses. In conclusion, SSRIs use of pregnant women during first trimester is associated with an increased risk of cardiovascular-related malformations of infants including septal defects. The safety of SSRIs use during first trimester should be discussed to pregnant women with depression.

Antidepressant use during pregnancy and the risk of major congenital malformations in a cohort of depressed pregnant women: an updated analysis of the Quebec Pregnancy Cohort

OBJECTIVE

Antidepressant use during gestation has been associated with risk of major congenital malformations but estimates can lack statistical power or be confounded by maternal depression. We aimed to determine the association between first-trimester exposure to antidepressants and the risk of major congenital malformations in a cohort of depressed/anxious women.

SETTING AND PARTICIPANTS

Data were obtained from the Quebec Pregnancy Cohort (QPC). All pregnancies with a diagnosis of depression or anxiety, or exposed to antidepressants in the 12 months before pregnancy, and ending with a live-born singleton were included.

OUTCOME MEASURES

Antidepressant classes (selective serotonin reuptake inhibitors (SSRI), serotonin-norepinephrine reuptake inhibitors (SNRI), tricyclic antidepressants (TCA) and other antidepressants) and types were individually compared with non-exposure during the first trimester (depressed untreated). Major congenital malformations overall and organ-specific malformations in the first year of life were identified.

RESULTS

18 487 pregnant women were included. When looking at the specific types of antidepressant used during the first trimester, only citalopram was increasing the risk of major congenital malformations (adjusted OR, (aOR) 1.36, 95% CI 1.08 to 1.73; 88 exposed cases), although there was a trend towards increased risk for the most frequently used antidepressants. Antidepressants with serotonin reuptake inhibition effect (SSRI, SNRI, amitriptyline (the most used TCA)) increased the risk of certain organ-specific defects: paroxetine increased the risk of cardiac defects (aOR 1.45, 95% CI 1.12 to 1.88), and ventricular/atrial septal defects (aOR 1.39, 95% CI 1.00 to 1.93); citalopram increased the risk of musculoskeletal defects (aOR 1.92, 95% CI 1.40 to 2.62), and craniosynostosis (aOR 3.95, 95% CI 2.08 to 7.52); TCA was associated with eye, ear, face and neck defects (aOR 2.45, 95% CI 1.05 to 5.72), and digestive defects (aOR 2.55, 95% CI 1.40 to 4.66); and venlafaxine was associated with respiratory defects (aOR 2.17, 95% CI 1.07 to 4.38).

CONCLUSIONS

Antidepressants with effects on serotonin reuptake during embryogenesis increased the risk of some organ-specific malformations in a cohort of pregnant women with depression.

[Affective disorders during pregnancy : Therapy with antidepressants and mood stabilizers]

BACKGROUND

It is not rare that the first manifestation or relapse of an affective disorder occurs during pregnancy. Should a pharmacological treatment be indicated, the selection of a suitable substance should be made on a basis which is as safe as possible. Even when treating women of childbearing age it should be assured that the psychotropic drug selected is safe to use during pregnancy as a high percentage of pregnancies are unplanned.

OBJECTIVE

When assessing the risks and benefits of psychopharmacotherapy in women who are or wish to get pregnant, not only the exposure of the child to potentially teratogenic drug effects but also potential complications during or after pregnancy and long-term neuropsychological issues need to be addressed.

METHODS

This article provides an overview of the currently available literature on the use of antidepressants and mood stabilizers during pregnancy.

RESULTS

A growing body of increasingly reliable data for many antidepressants and mood stabilizers are available, which allow a good prediction of their suitability for use during pregnancy and lactation.

CONCLUSION

When treating affective disorders during pregnancy an individual assessment of the benefits and risks for mother and child is required. The benefit of an appropriate treatment for the mother by including medication which may be potentially harmful to the child versus the risk of an insufficient treatment for the mother by excluding medication which may be potentially harmful to both the mother and the child need to be weighed up. When a suitable psychopharmacotherapy during pregnancy has been selected, the risk for mother and child can be minimized by incorporation of therapeutic drug monitoring.

Of rodents and humans: A comparative review of the neurobehavioral effects of early life SSRI exposure in preclinical and clinical research

Selective serotonin reuptake inhibitors (SSRIs) have been a mainstay pharmacological treatment for women experiencing depression during pregnancy and postpartum for the past 25 years. SSRIs act via blockade of the presynaptic serotonin transporter and result in a transient increase in synaptic serotonin. Long-lasting changes in cellular function such as serotonergic transmission, neurogenesis, and epigenetics, are thought to underlie the therapeutic benefits of SSRIs. In recent years, though, growing evidence in clinical and preclinical settings indicate that offspring exposed to SSRIs in utero or as neonates exhibit long-lasting behavioral adaptions. Clinically, children exposed to SSRIs in early life exhibit increased internalizing behavior reduced social behavior, and increased risk for depression in adolescence. Similarly, rodents exposed to SSRIs perinatally exhibit increased traits of anxiety- or depression-like behavior. Furthermore, certain individuals appear to be more susceptible to early life SSRI exposure than others, suggesting that perinatal SSRI exposure may pose greater risks for negative outcome within certain populations. Although SSRIs trigger a number of intracellular processes that likely contribute to their therapeutic effects, early life antidepressant exposure during critical neurodevelopmental periods may elicit lasting negative effects in offspring. In this review, we cover the basic development and structure of the serotonin system, how the system is affected by early life SSRI exposure, and the behavioral outcomes of perinatal SSRI exposure in both clinical and preclinical settings. We review recent evidence indicating that perinatal SSRI exposure perturbs the developing limbic system, including altered serotonergic transmission, neurogenesis, and epigenetic processes in the hippocampus, which may contribute to behavioral domains (e.g., sociability, cognition, anxiety, and behavioral despair) that are affected by perinatal SSRI treatment. Identifying the molecular mechanisms that underlie the deleterious behavioral effects of perinatal SSRI exposure may highlight biological mechanisms in the etiology of mood disorders. Moreover, because recent studies suggest that certain individuals may be more susceptible to the negative consequences of early life SSRI exposure than others, understanding mechanisms that drive such susceptibility could lead to individualized treatment strategies for depressed women who are or plan to become pregnant.

Pharmacotherapy of obsessive-compulsive disorder during pregnancy: a clinical approach

Obsessive-compulsive disorder (OCD) is a relatively common psychiatric disorder in the perinatal period. However, specific pharmacological treatment approaches for patients with OCD during pregnancy have not been satisfactorily discussed in the literature. In addition, there are no randomized controlled studies on the treatment of this disorder during pregnancy. The present paper discusses the pharmacological treatment of OCD in the light of data on the safety of antipsychotics and serotonergic antidepressants during pregnancy and their efficacy in the non-perinatal period. Treatment decisions should be individualized because the risk-benefit profile of pharmacotherapy is an important issue in the treatment of pregnant women with any psychiatric diagnosis.

The risk of major cardiac malformations associated with paroxetine use during the first trimester of pregnancy: a systematic review and meta-analysis

AIMS

The aim of this study was to perform an up-to-date meta-analysis on the risk of cardiac malformations associated with gestational exposure to paroxetine, taking into account indication, study design and reference category.

METHOD

A systematic review of studies published between 1966 and November 2015 was conducted using embase and MEDLINE. Studies reporting major malformations with first trimester exposure to paroxetine were included. Potentially relevant articles were assessed and relevant data extracted to calculate risk estimates. Outcomes included any major malformations and major cardiac malformations. Pooled odds ratios and 95% confidence intervals were calculated using random-effects models.

RESULTS

Twenty-three studies were included. Compared with non-exposure to paroxetine, first trimester use of paroxetine was associated with an increased risk of any major congenital malformations combined (pooled OR 1.23, 95% CI 1.10, 1.38; n = 15 studies), major cardiac malformations (pooled OR 1.28, 95% CI 1.11, 1.47; n = 18 studies), specifically bulbus cordis anomalies and anomalies of cardiac septal closure (pooled OR 1.42, 95% CI 1.07, 1.89; n = 8 studies), atrial septal defects (pooled OR 2.38, 95% CI 1.14, 4.97; n = 4 studies) and right ventricular outflow track defect (pooled OR 2.29, 95% CI 1.06, 4.93; n = 4 studies). Although the estimates varied depending on the comparator group, study design and malformation detection period, a trend towards increased risk was observed.

CONCLUSIONS

Paroxetine use during the first trimester of pregnancy is associated with an increased risk of any major congenital malformations and cardiac malformations. The increase in risk is not dependent on the study method or population.

Use of prescription medicines in Australian women of child-bearing age

Background

This study aimed to examine current utilisation of prescribed medicines amongst Australian women of child-bearing age, with a particular focus on the extent of use of medicines in Category D and X risk groups, which are moderate and high risk teratogens, respectively. The use of those medicines may pose risk of birth defects in pregnant women.

Methods

A retrospective cross-sectional study was undertaken involving all women of child-bearing age (15 to 44 years) who were dispensed medicines in 2013 using the 10 % random sample of dispensing data from the Australian Government Department of Human Services. Dispensing patterns were reported by medicine, therapeutic class, pregnancy risk category and women’s age.

Results

Over one-third of women aged 15 to 44 years received at least one prescribed medicine in 2013. Psychoanaleptics, antibiotics and analgesics were the top three classes. Around 9 % of all dispensings were for medicines from risk category D, with statins, agents acting on renin-angiotensin system, and some anti-epileptic agents being the most commonly used. Both statins and agents acting on renin-angiotensin system showed increasing use with age, estimated to be 35,600 women nationally for each group. Collectively between 2 % and 4 % of women used anti-epileptics from risk category D in each year of age, with overall use estimated to be 51,000 women nationally. Below 1 % of all dispensings were for category X medicines, mainly isotretinoin.

Conclusions

It is important for medical practitioners to offer counselling around pregnancy planning and the risk of birth defects when prescribing moderate or high risk teratogens to women in child-bearing age. For the antihypertensives and some anti-epileptics, alternative medicines with lower risk categorization are available.

Mindfulness-Based Cognitive Therapy for Perinatal Women with Depression or Bipolar Spectrum Disorder

The perinatal period is a high-risk time for mood deterioration among women vulnerable to depression. This study examined feasibility, acceptability, and improvement associated with mindfulness-based cognitive therapy (MBCT) in perinatal women with major depressive disorder (MDD) or bipolar spectrum disorder (BSD). Following a diagnostic evaluation, 39 perinatal women with a lifetime history of MDD (n = 27) or BSD (n = 12) enrolled in an 8-week program of MBCT classes (2 h each) that incorporated meditation, yoga, and mood regulation strategies. Participants were pregnant (n = 12), planning pregnancy (n = 11), or up to 1-year postpartum (n = 16). Participants were self-referred and most had subthreshold mood symptoms. Assessments of depression, (hypo)mania, and anxiety were obtained by interview and self-report at baseline, post-treatment and at 1- and 6-month post-treatment. Women with a history of MDD were more likely to complete the classes than women with BSD. Of 32 women who completed the classes, 7 (21.9 %) had a major depressive episode during the 6-month post-treatment follow-up. On average, participants with MDD reported improvements in depression from pre- to post-treatment. Mood improvement was not observed in the BSD group. In the full sample, improvements in depression symptoms across time points were associated with increasing mindful tendency scores. This study was limited by its uncontrolled design, heterogeneous sample, and questionnaire-based assessment of mindfulness skills. MBCT may be an important component of care for perinatal women with histories of major depression. Its applicability to perinatal women with BSD is unclear.

Antidepressants, anxiolytics, and hypnotics in pregnancy and lactation

AIMS

Untreated perinatal depression and anxiety disorders are known to have significant negative impact on both maternal and fetal health. Dilemmas still remain regarding the use and safety of psychotropics in pregnant and lactating women suffering from perinatal depression and anxiety disorders. The aim of the current paper was to review the existing evidence base on the exposure and consequences of antidepressants, anxiolytics, and hypnotics in women during pregnancy and lactation and to make recommendations for clinical decision making in management of these cases.

MATERIALS AND METHODS

We undertook a bibliographic search of Medline/PubMed (1972 through 2014), Science Direct (1972 through 2014), Archives of Indian Journal of Psychiatry databases was done. References of retrieved articles, reference books, and dedicated websites were also checked.

RESULTS AND CONCLUSIONS

The existing evidence base is extensive in studying multiple outcomes of the antidepressant or anxiolytic exposure in neonates, and some of the findings appear conflicting. Selective serotonin reuptake inhibitors are the most researched antidepressants in pregnancy and lactation. The available literature is criticized mostly on the lack of rigorous well designed controlled studies as well as lacunae in the methodologies, interpretation of statistical information, knowledge transfer, and translation of information. Research in this area in the Indian context is strikingly scarce. Appropriate risk-benefit analysis of untreated mental illness versus medication exposure, tailor-made to each patient's past response and preference within in the context of the available evidence should guide clinical decision making.

A pharmacological approach to panic disorder during pregnancy

Anxiety disorders and pregnancy may occur concurrently in some women. Although, several epidemiological or clinical studies about anxiety disorders in pregnancy exist, data on their treatment are very limited. Similar to other anxiety disorders, specific pharmacological treatment approaches in pregnant women with panic disorder (PD) have not been discussed in the literature. An important issue in the treatment of pregnant women with any psychiatric diagnosis is the risk-benefit profile of pharmacotherapy. Therefore, the treatment should be individualized. Untreated PD seems to be associated with several negative outcomes in the pregnancy. When the results of current study regarding the safety of pharmacological agents on the fetus and their efficacy in PD were gathered, sertraline, citalopram, imipramine and clomipramine at low doses for pure PD, and venlafaxine appeared to be more favorable than the other potential drugs. However, controlled studies examining optimum dosing, efficacy of antipanic medications and risk-benefit profile of intrauterine exposure to treated or untreated PD are urgently needed.

Caring for Opioid-dependent Pregnant Women: Prenatal and Postpartum Care Considerations

Pregnancy is an opportune time to identify opioid dependence, facilitate conversion to opioid maintenance treatment, and coordinate care with specialists in addiction medicine, behavioral health, and social services. Comprehensive prenatal care for opioid-dependent women involves the evaluation and the management of co-occurring psychiatric disorders, polysubstance use, infectious diseases, social stressors, and counseling regarding the importance of breastfeeding, contraception, and neonatal abstinence syndrome. Although the complex psychiatric, social, and environmental factors faced by this population pose significant challenges to obstetric care providers, the development of strong patient-provider relationships can facilitate the ability to deliver efficient and effective health care during pregnancy.

Pregnancy outcome after TNF-α inhibitor therapy during the first trimester: a prospective multicentre cohort study

AIMS

TNF-α inhibitors are considered relatively safe in pregnancy but experience is still limited. The aim of this study was to evaluate the risk of major birth defects, spontaneous abortion, preterm birth and reduced birth weight after first trimester exposure to TNF-α inhibitors.

METHODS

Pregnancy outcomes of women on adalimumab, infliximab, etanercept, certolizumab pegol or golimumab were evaluated in a prospective observational cohort study and compared with outcomes of a non-exposed random sample. The samples were drawn from pregnancies identified by institutes collaborating in the European Network of Teratology Information Services.

RESULTS

In total, 495 exposed and 1532 comparison pregnancies were contributed from nine countries. The risk of major birth defects was increased in the exposed (5.0%) compared with the non-exposed group (1.5%; adjusted odds ratio (ORadj ) 2.2, 95% CI 1.0, 4.8). The risk of preterm birth was increased (17.6%; ORadj 1.69, 95% CI 1.1, 2.5), but not the risk of spontaneous abortion (16.2%; adjusted hazard ratio [HRadj ] 1.06, 95% CI 0.7, 1.7). Birth weights adjusted for gestational age and sex were significantly lower in the exposed group compared to the non-exposed cohort (P = 0.02). As a diseased comparison group was not possible to ascertain, the influence of disease and treatment on birth weight and preterm birth could not be differentiated.

CONCLUSIONS

TNF-α inhibitors may carry a risk of adverse pregnancy outcome of moderate clinical relevance. Considering the impact of insufficiently controlled autoimmune disease on the mother and the unborn child, TNF-α inhibitors may nevertheless be a treatment option in women with severe disease refractory to established immunomodulatory drugs.

Nicotine replacement therapy in pregnancy and major congenital anomalies in offspring

BACKGROUND AND OBJECTIVES

Nicotine replacement therapy (NRT) is now being used as a smoking cessation aid during pregnancy, although little is known about fetal safety. We assessed the relationship between early pregnancy exposure to NRT or smoking with major congenital anomalies (MCA) in offspring.

METHODS

We studied 192,498 children born in the United Kingdom between 2001 and 2012 with linked mother-child primary care records. The absolute risks of MCAs in the NRT group (women prescribed NRT during the first trimester or 1 month before conception [and therefore likely consumed during the first trimester]) and odds ratios (ORs) and 99% confidence intervals (CIs) were compared with those of women who smoked during pregnancy and with a control group (women who neither smoked nor were prescribed NRT); logistic regression models adjusted for maternal morbidities that increase MCA risk were used for analysis.

RESULTS

MCA prevalence was 288 per 10,000 live births (5535 children with ≥ 1 MCA). Maternal morbidities were most common in the NRT group (35%) followed by smokers (27%) and the control group (20%). Compared with the control group, adjusted ORs for MCAs in the NRT group and smokers were 1.12 (99% CI: 0.84-1.48) and 1.05 (99% CI: 0.89-1.23), respectively. The OR comparing the NRT group directly with smokers was 1.07 (99% CI: 0.78-1.47). There were no statistically significant associations between maternal NRT and system-specific anomalies except for respiratory anomalies (OR: 4.65 [99% CI: 1.76-12.25]; absolute risk difference: 3 per 1000 births), which was based on 10 exposed cases.

CONCLUSIONS

For most system-specific MCAs, we found no statistically significant increased risks associated with maternal NRT prescribed during pregnancy, except for respiratory anomalies. Although this study is the largest published to date, NRT use in pregnancy remains rare; thus, the statistical power was limited. Higher morbidities in those women prescribed NRT may also be an explanatory factor. Nevertheless, absolute MCA risks were similar between women who smoked and those prescribed NRT during pregnancy.

Controversies about the use of antidepressants in pregnancy

There is controversy about the use of antidepressant medication during pregnancy. Decisions about their use are affected by understanding the risks of these medications causing pregnancy loss, congenital malformations, neonatal adaptation syndrome, persistent pulmonary hypertension of the newborn, autism spectrum disorder, or long-term neurocognitive deficits. Although some research has raised concerns about antidepressants causing harm to the fetus and neonate, other studies have disputed these findings or noted that any risks found do not exceed the risk of congenital problems found in 1% to 3% of neonates in the general population. Untreated depression during pregnancy can also cause harm from poor diet, substance abuse, suicidal behavior, or prematurity. Decisions about the use of antidepressants during pregnancy must be based on a risk-benefit analysis based on the best evidence of the risks of treating or not treating maternal depression.

Early-life exposure to the SSRI paroxetine exacerbates depression-like behavior in anxiety/depression-prone rats

Selective serotonin reuptake inhibitor (SSRI) antidepressants are the mainstay treatment for the 10-20% of pregnant and postpartum women who suffer major depression, but the effects of SSRIs on their children's developing brain and later emotional health are poorly understood. SSRI use during pregnancy can elicit antidepressant withdrawal in newborns and increase toddlers' anxiety and social avoidance. In rodents, perinatal SSRI exposure increases adult depression- and anxiety-like behavior, although certain individuals are more vulnerable to these effects than others. Our study establishes a rodent model of individual differences in susceptibility to perinatal SSRI exposure, utilizing selectively bred Low Responder (bLR) and High Responder (bHR) rats that were previously bred for high versus low behavioral response to novelty. Pregnant bHR/bLR females were chronically treated with the SSRI paroxetine (10 mg/kg/day p.o.) to examine its effects on offspring's emotional behavior and gene expression in the developing brain. Paroxetine treatment had minimal effect on bHR/bLR dams' pregnancy outcomes or maternal behavior. We found that bLR offspring, naturally prone to an inhibited/anxious temperament, were susceptible to behavioral abnormalities associated with perinatal SSRI exposure (which exacerbated their Forced Swim Test immobility), while high risk-taking bHR offspring were resistant. Microarray studies revealed robust perinatal SSRI-induced gene expression changes in the developing bLR hippocampus and amygdala (postnatal days 7-21), including transcripts involved in neurogenesis, synaptic vesicle components, and energy metabolism. These results highlight the bLR/bHR model as a useful tool to explore the neurobiology of individual differences in susceptibility to perinatal SSRI exposure.

Treatment of nonpsychotic major depression during pregnancy: patient safety and challenges

In pregnant women with major depression, the overarching goal of treatment is to achieve or maintain maternal euthymia, thus limiting both maternal and fetal exposure to the harmful effects of untreated or incompletely treated depression. However, the absence of uniformly effective therapies with guaranteed obstetric and fetal safety makes the treatment of major depression during pregnancy among the most formidable of clinical challenges. Clinicians and patients are still faced with conflicting data and expert opinion regarding the reproductive safety of antidepressants in pregnancy, as well as large gaps in our understanding of the effectiveness of most antidepressants and nonpharmacological alternatives for treating antenatal depression. In this paper, we provide a clinically focused review of the available information on potential maternal and fetal risks of untreated maternal depression during pregnancy, the effectiveness of interventions for maternal depression during pregnancy, and potential obstetric, fetal, and neonatal risks associated with antenatal antidepressant use.

Antidepressant use in pregnancy and the risk of cardiac defects

BACKGROUND

Whether the use of selective serotonin-reuptake inhibitors (SSRIs) and other antidepressants during pregnancy is associated with an increased risk of congenital cardiac defects is uncertain. In particular, there are concerns about a possible association between paroxetine use and right ventricular outflow tract obstruction and between sertraline use and ventricular septal defects.

METHODS

We performed a cohort study nested in the nationwide Medicaid Analytic eXtract for the period 2000 through 2007. The study included 949,504 pregnant women who were enrolled in Medicaid during the period from 3 months before the last menstrual period through 1 month after delivery and their liveborn infants. We compared the risk of major cardiac defects among infants born to women who took antidepressants during the first trimester with the risk among infants born to women who did not use antidepressants, with an unadjusted analysis and analyses that restricted the cohort to women with depression and that used propensity-score adjustment to control for depression severity and other potential confounders.

RESULTS

A total of 64,389 women (6.8%) used antidepressants during the first trimester. Overall, 6403 infants who were not exposed to antidepressants were born with a cardiac defect (72.3 infants with a cardiac defect per 10,000 infants), as compared with 580 infants with exposure (90.1 per 10,000 infants). Associations between antidepressant use and cardiac defects were attenuated with increasing levels of adjustment for confounding. The relative risks of any cardiac defect with the use of SSRIs were 1.25 (95% confidence interval [CI], 1.13 to 1.38) in the unadjusted analysis, 1.12 (95% CI, 1.00 to 1.26) in the analysis restricted to women with depression, and 1.06 (95% CI, 0.93 to 1.22) in the fully adjusted analysis restricted to women with depression. We found no significant association between the use of paroxetine and right ventricular outflow tract obstruction (relative risk, 1.07; 95% CI, 0.59 to 1.93) or between the use of sertraline and ventricular septal defects (relative risk, 1.04; 95% CI, 0.76 to 1.41).

CONCLUSIONS

The results of this large, population-based cohort study suggested no substantial increase in the risk of cardiac malformations attributable to antidepressant use during the first trimester. (Funded by the Agency for Healthcare Research and Quality and the National Institutes of Health.).
