Use of antidepressants and anxiolytics in early pregnancy and the risk of preeclampsia and gestational hypertension: a prospective study

Effectiveness of smartphone-based music intervention on perinatal depression: protocol for a randomized controlled trial

BACKGROUND

Perinatal depression has become a global public health issue with a high prevalence rate. Multiple studies have confirmed the effectiveness of music intervention. Still, the current form of offline intervention ignores issues such as convenient transportation and the stigma of diseases that pregnant women are concerned about, resulting in poor adherence. This randomized controlled study will evaluate the impact of music intervention on depression, anxiety, and stress in perinatal women through the WeChat application. In addition, the usability of the WeChat application and the adherence of PND women will also be evaluated.

METHODS

This randomized, open, single-center parallel controlled trial randomly divided 110 women with perinatal depression who met the inclusion criteria into a smartphone-based music intervention group and usual care group in a 1:1 ratio. The main outcome measures will consist of EPDS and WeChat application usability score. The secondary outcome measures will consist of GAD-7, CPSS, and Knowledge-Attitude-Practice questionnaire scores.

DISCUSSION

This study will test the effectiveness of music intervention based on the WeChat application for perinatal depression and the usability of the WeChat application, to provide practical guidance for perinatal mental health care.

The effect of music intervention on depression in perinatal women: A systematic review

Objective

Perinatal depression has become a global public health problem, which not only harms the health of mothers and their offspring, but also increases the socio-economic burden, so early intervention is urgent. Music intervention is a low-cost and safe intervention method. This study endeavored to systematically integrate and quantitatively evaluate the effectiveness of music intervention for perinatal depression.

Methods

PubMed, Embase, Web of Science and Cochrane Library were searched systematically. The search period was up to September 1, 2024. The included studies were summarized and analyzed.

Results

A total of 1375 articles were obtained through preliminary search, and 13 of them were finally included. The effect of music intervention on perinatal depression was better than that of the control group (SMD = -0.53, 95%CI (-0.81, -0.26), p ＜ 0.05). Music intervention had no significant effect on alleviating anxiety (SMD = -0.47, 95%CI (-0.63, -0.31), p ＞ 0.05). However, the heterogeneity of the included studies was significant.

Conclusions

This study indicated that music intervention had a significant effect on alleviating perinatal depression, but the effect on anxiety was not significant. However, the results were highly heterogeneous, and large-scale, multi-center, and long-term studies are needed in the future to confirm this.

Five-Feature Models to Predict Preeclampsia Onset Time From Electronic Health Record Data: Development and Validation Study

BACKGROUND

 Preeclampsia is a potentially fatal complication during pregnancy, characterized by high blood pressure and the presence of excessive proteins in the urine. Due to its complexity, the prediction of preeclampsia onset is often difficult and inaccurate.

OBJECTIVE

 This study aimed to create quantitative models to predict the onset gestational age of preeclampsia using electronic health records.

METHODS

 We retrospectively collected 1178 preeclamptic pregnancy records from the University of Michigan Health System as the discovery cohort, and 881 records from the University of Florida Health System as the validation cohort. We constructed 2 Cox-proportional hazards models: 1 baseline model using maternal and pregnancy characteristics, and the other full model with additional laboratory findings, vitals, and medications. We built the models using 80% of the discovery data, tested the remaining 20% of the discovery data, and validated with the University of Florida data. We further stratified the patients into high- and low-risk groups for preeclampsia onset risk assessment.

RESULTS

 The baseline model reached Concordance indices of 0.64 and 0.61 in the 20% testing data and the validation data, respectively, while the full model increased these Concordance indices to 0.69 and 0.61, respectively. For preeclampsia diagnosed at 34 weeks, the baseline and full models had area under the curve (AUC) values of 0.65 and 0.70, and AUC values of 0.69 and 0.70 for preeclampsia diagnosed at 37 weeks, respectively. Both models contain 5 selective features, among which the number of fetuses in the pregnancy, hypertension, and parity are shared between the 2 models with similar hazard ratios and significant P values. In the full model, maximum diastolic blood pressure in early pregnancy was the predominant feature.

CONCLUSIONS

 Electronic health records data provide useful information to predict the gestational age of preeclampsia onset. Stratification of the cohorts using 5-predictor Cox-proportional hazards models provides clinicians with convenient tools to assess the onset time of preeclampsia in patients.

Risks associated with antidepressants in patients with hypertension during pregnancy: a retrospective cohort study

PURPOSE

In a cohort of pregnant women using antihypertensive drugs, we compared exposure to antidepressants versus no exposure and the possible association with birth weight, APGAR scores, NICU admission, and maternal admission to an obstetrical intensive care unit (OHC). It was hypothesized that pregnant women with hypertensive disorders using antidepressants are at greater risk of complications.

METHODS

A retrospective cohort study in a general teaching hospital in Zwolle, in the Middle-Northern part of The Netherlands. Finally, 58 pregnancies in the exposed group and 273 pregnancies in the reference group met all inclusion and exclusion criteria. We compared the neonate's birthweight between the exposed to antidepressants group and the reference group as the primary outcome. Secondary outcomes were the APGAR score at 1 and 5 min and obstetric high care (OHC) admission of the mother and neonatal intensive care unit (NICU) admission of the child.

RESULTS

We found no differences in birth weight in neonates of mothers with hypertensive disorders and whether or not to use antidepressants. Besides a possible higher risk of admission to an OHC in women with hypertension-complicated pregnancies using antidepressants, we found no other maternal or neonatal risks in this population.

CONCLUSION

We found no additional maternal or neonatal risks of using antidepressants prescribed to women with hypertension disorders during pregnancy.

Drug exposure during pregnancy in primary care: an algorithm and observational study from SIDIAP database, Catalunya, Spain

OBJECTIVES

To develop an algorithm to identify pregnancy episodes in women at childbearing age using SIDIAP (Information System for the Improvement of Research in Primary Care) data (Catalunya, Spain).To describe drugs dispensed during gestation.

DESIGN

Construction of an algorithm to identify all pregnancy episodes occurred from January 2011 to June 2020 in women aged 12-50. The variables used to create the algorithm include first day of last menstrual period, reasons for pregnancy termination and diagnoses registered in the primary healthcare records. Population-based cohort study including the pregnancy episodes identified by the algorithm.

SETTING

Catalonia, Spain.

PARTICIPANTS

All women aged 12-50 with at least one pregnancy episode occurred during January 2011-June 2020.

INTERVENTIONS

No interventions performed.

PRIMARY AND SECONDARY OUTCOME MEASURES

Identification of pregnancy episodes through an algorithm and description of drug exposure.

RESULTS

We identified 327 865 pregnancy episodes in 250 910 people with a mean age of 31.3 years. During the study period, 83.4% of the episodes were exposed to at least one drug. The most frequent groups dispensed were iron preparations (48% of pregnancy episodes), iodine therapy (40.2%), analgesics and antipyretics (28%), penicillins (19.8%), vitamin B12 plus folic acid (19.7%) and non-steroidal anti-inflammatory drugs (NSAIDs, 15.1%). The supplements were more frequently dispensed at least twice, and the drugs for acute conditions were mainly dispensed only once during the pregnancy episode.

CONCLUSIONS

We developed an algorithm to automatically identify the pregnancy periods in SIDIAP.We described prescription drugs used during pregnancy. The most used ones were supplements, analgesics, NSAID or antibiotics.SIDIAP might be an efficient database to study drug safety during pregnancy and the consequences of drug use in the offspring.

Depression and antidepressant treatment in the development of hypertensive disorders of pregnancy: Results from a prospective cohort study

BACKGROUND

Hypertensive disorders of pregnancy are associated with longer term cardiovascular risk. Understanding if depression or antidepressant use in pregnancy is associated with HDP is important in identifying those potentially vulnerable to poorer health in later life. This study examines if depression and antidepressants are associated with HDP.

METHODS

In all, 815 pregnant women were recruited within an Australian pregnancy cohort study at less than 20 weeks of pregnancy, all undertook the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and were assigned to four groups for this paper: those with unmedicated depression meeting criteria for current depression (n = 97), those taking selective serotonin reuptake inhibitors in early pregnancy (n = 101), those taking serotonin and noradrenaline reuptake inhibitors in early pregnancy (n = 31), and those without depression or taking antidepressant medication (control; n = 586). Women were then assessed again following birth. Hypertensive disorders of pregnancy were diagnosed according to the Society of Obstetric Medicine in Australia and New Zealand Guidelines.

RESULTS

Use of serotonin and noradrenaline reuptake inhibitors (SNRIs) (adjusted risk ratio = 9.10, 95% confidence interval = [3.82, 21.67]) and unmedicated depression (adjusted risk ratio = 3.11, 95% confidence interval = [1.32, 7.35]) were independently associated with significantly higher risk for developing hypertensive disorders of pregnancy compared to controls. Selective serotonin reuptake inhibitors (SSRIs) use did not confer any increased risk. Higher doses of SNRIs, but not selective serotonin reuptake inhibitors, were associated with significantly higher risk for developing HDP (adjusted risk ratio = 4.83, 95% confidence interval = [1.50, 15.58]).

CONCLUSIONS

Our findings suggest that those with depression in pregnancy and/or on an serotonin and noradrenaline reuptake inhibitor should have closer surveillance for the development of hypertensive disorders of pregnancy. These findings support treatment of depression in pregnancy, however, also the consideration of class of antidepressant.

Benefits and Risks of Antidepressant Drugs During Pregnancy: A Systematic Review of Meta-analyses

BACKGROUND

The prescription of antidepressant drugs during pregnancy has been steadily increasing for several decades. Meta-analyses (MAs), which increase the statistical power and precision of results, have gained interest for assessing the safety of antidepressant drugs during pregnancy.

OBJECTIVE

We aimed to provide a meta-review of MAs assessing the benefits and risks of antidepressant drug use during pregnancy.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a literature search on PubMed and Web of Science databases was conducted on 25 October, 2021, on MAs assessing the association between antidepressant drug use during pregnancy and health outcomes for the pregnant women, embryo, fetus, newborn, and developing child. Study selection and data extraction were carried out independently and in duplicate by two authors. The methodological quality of included studies was evaluated with the AMSTAR-2 tool. Overlap among MAs was assessed by calculating the corrected covered area. Data were presented in a narrative synthesis, using four levels of evidence.

RESULTS

Fifty-one MAs were included, all but one assessing risks. These provided evidence for a significant increase in the risks for major congenital malformations (selective serotonin reuptake inhibitors, paroxetine, fluoxetine, no evidence for sertraline; eight MAs), congenital heart defects (paroxetine, fluoxetine, sertraline; 11 MAs), preterm birth (eight MAs), neonatal adaptation symptoms (eight MAs), and persistent pulmonary hypertension of the newborn (three MAs). There was limited evidence (only one MA for each outcome) for a significant increase in the risks for postpartum hemorrhage, and with a high risk of bias, for stillbirth, impaired motor development, and intellectual disability. There was inconclusive evidence, i.e., discrepant results, for an increase in the risks for spontaneous abortion, small for gestational age and low birthweight, respiratory distress, convulsions, feeding problems, and for a subsequent risk for autism with an early antidepressant drug exposure. Finally, MAs provided no evidence for an increase in the risks for gestational hypertension, preeclampsia, and for a subsequent risk for attention-deficit/hyperactivity disorder. Only one MA assessed benefits, providing limited evidence for preventing relapse in severe or recurrent depression. Effect sizes were small, except for neonatal symptoms (small to large). Results were based on MAs in which overall methodological quality was low (AMSTAR-2 score = 54.8% ± 12.9%, [19-81%]), with a high risk of bias, notably indication bias. The corrected covered area was 3.27%, which corresponds to a slight overlap.

CONCLUSIONS

This meta-review has implications for clinical practice and future research. First, these results suggest that antidepressant drugs should be used as a second-line treatment during pregnancy (after first-line psychotherapy, according to the guidelines). The risk of major congenital malformations could be prevented by observing guidelines that discourage the use of paroxetine and fluoxetine. Second, to decrease heterogeneity and bias, future MAs should adjust for maternal psychiatric disorders and antidepressant drug dosage, and perform analyses by timing of exposure.

Selective serotonin reuptake inhibitors and preeclampsia: A quality assessment and meta-analysis

Serotonin modulates vascular, immune, and neurophysiology and is dysregulated in preeclampsia. Despite biological plausibility that selective serotonin reuptake inhibitors (SSRIs) prevent preeclampsia pathophysiology, observational studies have indicated increased risk and providers may be hesitant. The objective of this meta-analysis and quality assessment was to evaluate the evidence linking SSRI use in pregnancy to preeclampsia/gestational hypertension. PubMed was searched through June 5, 2020 manually and using combinations of terms: "preeclampsia", "serotonin", and "SSRI". This review followed MOOSE guidelines. Inclusion criteria were: 1) Observational cohort or population study, 2) exposure defined as SSRI use during pregnancy, 3) cases defined as preeclampsia or gestational hypertension, and 4) human participants. Studies were selected that addressed the hypothesis that gestational SSRI use modulates preeclampsia and/or gestational hypertension risk. Review Manager Web was used to synthesize study findings. Articles were read and scored (Newcastle-Ottawa Quality Assessment Scale) for quality by two independent reviewers. Publication bias was assessed using a funnel plot and the Egger test. Of 179 screened studies, nine were included. The pooled risk ratio (random effects model) was 1.43 (95 % CI: 1.15-1.78, P < 0.001; range 0.96-4.86). Two studies were rated as moderate quality (both with total score of 6); others were high quality. Heterogeneity was high (I2 = 88 %) and funnel asymmetry was significant (p < 0.00001). Despite evidence for increased preeclampsia risk with SSRIs, shared risk factors and other variables are poorly controlled. Depression treatment should not be withheld due to perceived gestational hypertension risk. Mechanistic evidence for serotonin modulation in preeclampsia demonstrates a need for future research.

The role of prenatal exposure to antidepressants, anxiolytic, and hypnotics and its underlying illness on the risk of miscarriage using BIFAP database

Purpose

Despite the notable increase on the prescription of antidepressants and anxiolytics during pregnancy, recommendation on maintaining the treatment during prenatal period is still controversial. We aimed to separately assess the role of effects of the antidepressants and anxiolytic and the underlying illness, controlled by potential confounding associated with miscarriage onset.

Methods

We used data from a validated pregnant cohort aged 15–49 years from 2002 to 2016 using BIFAP database. All confirmed miscarriages were used to perform a nested control analysis using conditional logistic regression. Women were classified according to use of each drug of interest into four mutually exclusive groups: nonusers, users only during prepregnancy, continuers, and initiators during first trimester. Adjusted odds ratios (aORs) for major confounders during pregnancy such as number of visits to primary care practitioners visits, obesity, smoking, HTA, diabetes with 95% confidence intervals were calculated.

Results

Compared with nonusers, antidepressants continuers had the highest increased risk of miscarriage aOR (95%) of 1.29 (1.13–1.46), being continuers of paroxetine and fluoxetine the antidepressants with the strongest association. Likewise, continuers of anxiolytics and initiators showed an increased risk of 1.19 (1.04–1.37) and 1.30 (1.13–1.50). When separating the effect between the condition itself or the treatment, women exposed during first trimester, regardless treatment duration and/or the underlying illness, had the highest risk 1.27 (1.08–1.51) for antidepressants and 1.25 (1.13–1.39) for anxiolytics.

Conclusions

Our analysis showed an association between prenatal exposure to antidepressants and anxiolytics and miscarriage onset after controlling by potential confounding adjusting for confounders and the underlying illness. This association was not supported for hypnotic medications. Further studies are warranted to evaluate the risk of miscarriage among subpopulation of pregnant women requiring these medications.

Sex-specific association of high maternal psychological stress during pregnancy on newborn birthweight

Birthweight is an important predictor of newborn health and has been linked to maternal psychological stress during pregnancy. However, it is unclear whether prenatal stress affects birthweight similarly for both male and female infants. We used a well-established pregnancy cohort to investigate the impact of high maternal psychological stress during pregnancy on birthweight as a function of infant sex. Overall, 5702 mother-newborn pairs were analysed. Of these, 198 mothers reported high levels of stress using the Psychological Stress Measure (nine-items version; PSM-9). Maternal psychological stress was assessed between the 24^th and 28^th week of gestation and analyses were performed jointly and independently as a function of neonatal sex (separate analyses for male and female infants). Newborns exposed to high maternal psychological stress during pregnancy (a score above 26 measured using the PSM-9 questionnaire, corresponding to >97.5^th percentile) were compared to newborns of mothers who reported lower stress. ANCOVAs revealed that high levels of maternal stress during pregnancy were linked to infant birthweight as a function of infant sex. Male infants of mothers who reported high levels of stress had a greater birthweight whereas female infants had a lower birthweight under the same conditions, in comparison to mothers who did not report greater levels of stress. Although the effect size is small, these results underline the possibility that male and female fetuses may use different strategies when adapting to maternal adversity and highlight the need to consider infant sex as a moderator of the association between maternal psychological stress during pregnancy and infant birthweight.

Antidepressant use during pregnancy and development of preeclampsia: A focus on classes of action and specific transporters/receptors targeted by antidepressants

OBJECTIVE

The association between antidepressants and preeclampsia has been inconsistently reported. Given the compound-specific variable affinity for different transporters/receptors, their effect on preeclampsia risk could differ. Our study examined the risk of preeclampsia (and its subtypes) following exposure to different classes of antidepressants, also accounting for specific transporters/receptors targeted by antidepressants.

METHODS

We conducted a cohort study, combining data from the Netherlands Perinatal Registry and the PHARMO Database Network. Exposure to antidepressants was examined from conception to week 20 of gestation; extended use thereafter was also studied. Antidepressants were categorized according to classes [selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), serotonin-norepinephrine reuptake inhibitors (SNRIs), monoamine oxidase inhibitors (MAOIs) and other antidepressants] and according to target transporters/receptors. Women not using any antidepressants during 15 months before delivery were included as reference.

RESULTS

We included 2,103 exposed and 95,376 reference women. Preeclampsia occurred in 70 exposed women (15 early-onset, 55 late-onset) and in 2,582 reference women (387 early-onset, 2,195 late-onset). TCA monotherapy (214 women) was associated with an increased risk of preeclampsia (n = 15, RR 2.46, 95% CI 1.51-4.02) and late-onset preeclampsia (n = 12, RR 2.41, 95% CI 1.39-4.17, early-onset could not be evaluated). No association was detected with SSRIs, SNRIs and MAOIs. We did observe an increased risk of early-onset preeclampsia following exposure to 5-HT2A antagonizing antidepressants (6/405 women, excluding TCA users, RR 3.56, 95% CI 1.60-7.94).

CONCLUSIONS

Our results support an increased risk of preeclampsia and the late-onset subtype among TCA users. The association between 5-HT2A antagonists and the early-onset subtype needs to be interpreted with caution based on the relatively small number of exposed cases.

Hypertensive disorders in pregnancy and child development at 36 months in the All Our Families prospective cohort study

Hypertensive disorders in pregnancy (HDP) are associated with increased risk of offspring neurodevelopmental disorders, suggesting long-term adverse impacts on fetal brain development. However, the relationship between HDP and deficits in general child development is unclear. Our objective was to assess the association between HDP and motor and cognitive developmental delay in children at 36 months of age. We analyzed data from the All Our Families community-based cohort study (n = 1554). Diagnosis of HDP-gestational or chronic hypertension, preeclampsia, or eclampsia-was measured through medical records. Child development was measured by maternal-report on five domains of the Ages and Stages Questionnaire (ASQ-3). Standardized cut-off scores were used to operationalize binary variables for any delay, motor delay, and cognitive delay. We calculated adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) using logistic regression, sequentially controlling for potential confounders followed by factors suspected to lie on the causal pathway. Overall, 8.0% of women had HDP and hypertension-exposed children had higher prevalence of delay than unexposed children. Hypertension-exposed children had elevated risk for developmental delay, but CIs crossed the null. The aRRs quantifying the fully adjusted effect of HDP on child development were 1.19 (95% CI 0.92, 1.53) for any delay, 1.18 (95% CI 0.86, 1.61) for motor delay, and 1.24 (95% CI 0.83, 1.85) for cognitive delay. We did not find a statistically significant association between HDP and developmental delay. Confidence intervals suggest that children exposed to HDP in utero have either similar or slightly elevated risk of any, motor, and cognitive delay at 36 months after controlling for maternal and obstetric characteristics. The observed direction of association aligns with evidence of biological mechanisms whereby hypertensive pathology can disrupt fetal neurodevelopment; however, more evidence is needed. Findings may have implications for early developmental monitoring and intervention following prenatal hypertension exposure.

Prenatal antidepressant use and the implication of hypertensive disorders during pregnancy

BACKGROUND

Evidence for the association between prenatal antidepressant use and the development of hypertensive disorders of pregnancy is inconsistent. Previous studies have reported that antidepressant use during pregnancy increases the risk for gestational hypertension and preeclampsia, but the results of these studies are potentially confounded by important methodologic limitations. Furthermore, it remains unknown whether a higher cumulative dose of antidepressant increases the risk for hypertensive disorders of pregnancy.

OBJECTIVE

This study aimed to investigate the association between prenatal antidepressant use and the risk for hypertensive disorders of pregnancy and the potential effect of a higher cumulative antidepressant dose.

STUDY DESIGN

This retrospective cohort study used data from the Health and Welfare Database in Taiwan. Pregnant women with depression aged 18 to 49 years were enrolled as part of the study population. Prenatal antidepressant use was defined as at least 1 dispensing record of an antidepressant between the conception date and 20 weeks of gestation. Antidepressant users were further divided into groups according to the cumulative defined daily dose based on whether they took the defined daily dose for ≤10 weeks (low cumulative dose group ≤70 cumulative defined daily dose) or for >10 weeks (high cumulative dose group >70 cumulative defined daily dose). The primary outcome was hypertensive disorders of pregnancy defined as the diagnosis of either gestational hypertension or preeclampsia during the period from 20 weeks of gestation to delivery. Propensity score matching and stabilized inverse probability of treatment weighting were used to balance the confounders between the comparison groups. A robust Cox regression model was used to evaluate the association between exposure and outcome.

RESULTS

A total of 5664 pregnant women with depression were included in the study (2832 antidepressant users matched to 2832 antidepressant nonusers). Prenatal antidepressant use was not associated with an increased risk for hypertensive disorders of pregnancy (adjusted hazard ratio, 0.89; 95% confidence interval, 0.67-1.18). However, among antidepressant users, the risk for hypertensive disorders of pregnancy was higher among women with a higher cumulative defined daily dose than among women with a lower cumulative defined daily dose (adjusted hazard ratio, 2.46; 95% confidence interval, 1.05-5.74).

CONCLUSION

No association was found between antidepressant use and the development of hypertensive disorders of pregnancy. However, women taking higher cumulative doses of antidepressants were at greater risk. More frequent or regular monitoring of blood pressure may be warranted in women on high cumulative doses of antidepressants.

Effect of Selected Antidepressants on Placental Homeostasis of Serotonin: Maternal and Fetal Perspectives

Depression is a prevalent condition affecting up to 20% of pregnant women. Hence, more than 10% are prescribed antidepressant drugs, mainly serotonin reuptake inhibitors (SSRIs) and selective serotonin and noradrenaline reuptake inhibitors (SNRIs). We hypothesize that antidepressants disturb serotonin homeostasis in the fetoplacental unit by inhibiting serotonin transporter (SERT) and organic cation transporter 3 (OCT3) in the maternal- and fetal-facing placental membranes, respectively. Paroxetine, citalopram, fluoxetine, fluvoxamine, sertraline, and venlafaxine were tested in situ (rat term placenta perfusion) and ex vivo (uptake studies in membrane vesicles isolated from healthy human term placenta). All tested antidepressants significantly inhibited SERT- and OCT3-mediated serotonin uptake in a dose-dependent manner. Calculated half-maximal inhibitory concentrations (IC₅₀) were in the range of therapeutic plasma concentrations. Using in vitro and in situ models, we further showed that the placental efflux transporters did not compromise mother-to-fetus transport of antidepressants. Collectively, we suggest that antidepressants have the potential to affect serotonin levels in the placenta or fetus when administered at therapeutic doses. Interestingly, the effect of antidepressants on serotonin homeostasis in rat placenta was sex dependent. As accurate fetal programming requires optimal serotonin levels in the fetoplacental unit throughout gestation, inhibition of SERT-/OCT3-mediated serotonin uptake may help explain the poor outcomes of antidepressant use in pregnancy.

Antidepressant Drugs Effects on Blood Pressure

Individuals suffering from depressive disorders display a greater incidence of hypertension compared with the general population, despite reports of the association between depression and hypotension. This phenomenon may depend, at least in part, on the use of antidepressant drugs, which may influence blood pressure through different effects on adrenergic and serotoninergic pathways, as well as on histaminergic, dopaminergic, and cholinergic systems. This review summarizes extant literature on the effect of antidepressant drugs on blood pressure. Selective serotonin reuptake inhibitors are characterized by limited effects on autonomic system activity and a lower impact on blood pressure. Thus, they represent the safest class-particularly among elderly and cardiovascular patients. Serotonin-norepinephrine reuptake inhibitors, particularly venlafaxine, carry a greater risk of hypertension, possibly related to greater effects on the sympathetic nervous system. The norepinephrine reuptake inhibitor reboxetine is considered a safe option because of its neutral effects on blood pressure in long-term studies, even if both hypotensive and hypertensive effects are reported. The dopamine-norepinephrine reuptake inhibitor bupropion can lead to blood pressure increases, usually at high doses, but may also cause orthostatic hypotension, especially in patients with cardiovascular diseases. The norepinephrine-serotonin modulators, mirtazapine and mianserin, have minimal effects on blood pressure but may rarely lead to orthostatic hypotension and falls. These adverse effects are also observed with the serotonin-reuptake modulators, nefazodone and trazodone, but seldomly with vortioxetine and vilazodone. Agomelatine, the only melatonergic antidepressant drug, may also have limited effects on blood pressure. Tricyclic antidepressants have been associated with increases in blood pressure, as well as orthostatic hypotension, particularly imipramine. Oral monoamine-oxidase inhibitors, less frequently skin patch formulations, have been associated with orthostatic hypotension or, conversely, with hypertensive crisis due to ingestion of tyramine-containing food (i.e., cheese reaction). Lastly, a hypertensive crisis may complicate antidepressant treatment as a part of the serotonin syndrome, also including neuromuscular, cognitive, and autonomic dysfunctions. Clinicians treating depressive patients should carefully consider their blood pressure status and cardiovascular comorbidities because of the effects of antidepressant drugs on blood pressure profiles and potential interactions with antihypertensive treatments.

Clinical characteristics, gestational weight gain and pregnancy outcomes in women with a history of gestational diabetes mellitus

BACKGROUND

Pregnant women with a history of gestational diabetes mellitus (GDM) are at high risk of GDM. It is unclear whether this population has pregnancy characteristics different from the general population. Whether these features affect the perinatal outcome has not yet been elucidated.

METHODS

A retrospective study was conducted, including baseline characteristics, laboratory data, gestational weight gain (GWG), and pregnancy outcomes of 441 pregnant women with prior GDM. Besides, 1637 women without a history of GDM treated in the same period were randomly selected as the control group. The above indicators of the two groups were compared. Multivariable logistic regression analysis was performed to investigate how GWG was associated with perinatal outcomes for previous GDM women.

RESULTS

Among women with GDM history, triglycerides (TG) and fasting plasma glucose (FPG) in the 1st trimester were higher than those without GDM history. GWG was lower in women with prior GDM relative to the control group at various pregnancy stages. However, women with GDM history had a higher risk of developing GDM (OR 3.25, 95% CI 2.26-4.68) and pregnancy-induced hypertension (OR 1.50, 95% CI 1.05-2.45). In women with previous GDM, excessive GWG before OGTT exhibited a positive correlation with pregnancy-induced hypertension (OR 1.47, 95% CI 1.05-3.32), while inadequate GWG was not a protective factor for GDM and pregnancy-induced hypertension.

CONCLUSION

Women with prior GDM have glucose and lipid metabolism disorders in the 1st trimester. Limited reduction of GWG before oral glucose tolerance test (OGTT) was insufficient to offset the adverse effects of glucose and lipid metabolism disorders in women with previous GDM. Relevant interventions may be required at early stage or even before pregnancy.

Contemporary management of unipolar depression in the perinatal period

Introduction: There is increasing recognition that antenatal depression and postpartum depression are highly prevalent and have significant impact on maternal and child health.Areas Covered: In the initial part of the manuscript, the authors review the epidemiology of antenatal and postpartum depression and its impact on maternal and child health. The later part of the manuscript reviews the current status of the medical management and psychosocial interventions targeting perinatal depression.Expert Opinion: Perinatal depression is the focus of several studies with increasing interest in developing effective interventions. While several psychosocial interventions targeting maternal depressive symptoms during pregnancy and postpartum are available, more studies are needed to address the need for safe and efficacious strategies for the use of antidepressant medication during pregnancy and in the postpartum period.

The association between mental illness, psychotropic medication use and hypertensive disorders in pregnancy: A multicentre study

OBJECTIVES

Women with severe mental illnesses (SMI) may have elevated rates of hypertensive disorders in pregnancy (HDP) due to an accumulation of risk factors. This study aims to determine the prevalence rate of HPD within a population of women with SMI and to report on rates within different mental illness diagnoses and types of medication exposure.

STUDY DESIGN

A retrospective multicentre study of 521 pregnant women attending specialised antenatal clinics for the management of established SMI.

MAIN OUTCOME MEASURES

Measures included sociodemographic characteristics, pregnancy complications, mental health diagnosis and psychotropic medication use.

RESULTS

Overall, 14% of women in the study had HDP. Compared to women with non-affective psychotic and other non-psychotic disorders (10.3%), women with depression and anxiety disorders demonstrated an increased risk of having a diagnosis of HDP (18.8%; RR = 1.82 [95% CI: 1.01, 3.29], p = .048). Log-binomial regression demonstrated that both a BMI in the overweight and obese range (RR = 3.37 [95% CI: 1.04, 10.95], p = .044) and continuous SNRI treatment throughout pregnancy (RR = 2.79 [95% CI; 1.33, 5.83], p = .006) were significant predictors of HDP, after adjusting for maternal age, gestational diabetes, and other mental health diagnoses.

CONCLUSION

Women with severe mental illnesses have elevated risk of developing HPD. Management remains complex and should address their comorbid risk profiles, and weigh up the risks and benefits of psychotropic medication use, given these results provide evidence of elevated rates of HDP associated with exposure to SNRI when taken throughout pregnancy.

Comparative risks and predictors of preeclamptic pregnancy in the Eastern, Western and developing world

Preeclampsia (PE) is a complication of pregnancy characterized by hypertension (HTN-Preg), and often proteinuria. If not managed promptly, PE could lead to eclampsia and seizures. PE could also lead to intrauterine growth restriction (IUGR) and prematurity at birth. Although PE is a major cause of maternal and fetal morbidity and mortality, the underlying mechanisms are unclear. Also, there is a wide variability in the incidence of PE, ranging between 2 and 8% of pregnancies in the Eastern, Western and Developing world, suggesting regional differences in the risk factors and predictors of the pregnancy-related disorder. Several demographic, genetic, dietary and environmental factors, as well as maternal circulating biomarkers have been associated with PE. Demographic factors such as maternal race and ethnicity could play a role in PE. Specific genetic polymorphisms have been identified in PE. Maternal age, parity, education and socioeconomic status could be involved in PE. Dietary fat, protein, calcium and vitamins, body weight, and environmental factors including climate changes and air pollutants could also play a role in PE. Several circulating cytoactive factors including anti-angiogenic factors and cytokines have also been associated with PE. Traditional midwifery care is a common practice in local maternity care units, while advanced perinatal care and new diagnostic tools such as uterine artery Doppler velocimetry have been useful in predicting early PE in major medical centers. These PE risk factors, early predictors and diagnostic tools vary vastly in different regions of the Eastern, Western and Developing world. Further understanding of the differences in the demographic, genetic, dietary and environmental factors among pregnant women in different world regions should help in designing a region-specific cluster of risk factors and predictors of PE, and in turn provide better guidance for region-specific tools for early detection and management of PE.

Depressed mood and anxiety as risk factors for hypertensive disorders of pregnancy: a systematic review and meta-analysis

BACKGROUND

Psychosocial factors have been implicated as both a cause and consequence of hypertension in the general population but are less understood in relation to hypertensive disorders of pregnancy (HDP). The aims of this review were to (1) synthesize the existing literature examining associations between depression and/or anxiety in pregnancy and HDP and (2) assess if depression and/or anxiety in early pregnancy was a risk factor for HDP.

METHODS

A comprehensive search of Medline, Embase, CINAHL, and PsycINFO was conducted from inception to March 2020 using terms related to 'pregnancy', 'anxiety', 'depression', and 'hypertensive disorders'. English-language cohort and case-control studies were included if they reported: (a) the presence or absence of clinically significant symptoms of depression/anxiety, or a medical record diagnosis of depression or an anxiety disorder in pregnancy; (b) diagnosis of HDP; and/or (c) data comparing the depressed/anxious group to the non-depressed/anxious group on HDP. Data related to depression/anxiety, HDP, study characteristics, and aspects related to study quality were extracted independently by two reviewers. Random-effects meta-analyses of estimated pooled relative risks (RRs) were conducted for depression/anxiety in pregnancy and HDP.

RESULTS

In total, 6291 citations were retrieved, and 44 studies were included across 61.2 million pregnancies. Depression and/or anxiety were associated with HDP [RR = 1.39; 95% confidence interval (CI) 1.25-1.54].

CONCLUSIONS

When measurement of anxiety or depression preceded diagnosis of hypertension, the association remained (RR = 1.27; 95% CI 1.07-1.50). Women experiencing depression or anxiety in pregnancy have an increased prevalence of HDP compared to their non-depressed or non-anxious counterparts.

Patterns of prenatal antidepressant exposure and risk of preeclampsia and postpartum haemorrhage

BACKGROUND

Antidepressant use later in pregnancy has been associated with preeclampsia and postpartum haemorrhage (PPH) in some studies.

OBJECTIVES

To evaluate the association between patterns of prenatal antidepressant dose across gestationand risk of precclampsia and PPH.

METHODS

We utilised OptumLabs® Data Warehouse (2012-2016) administrative health care claims, identifying 226 932 singleton liveborn deliveries for this retrospective cohort study. Antidepressant dispensing doses were converted to fluoxetine equivalents. Using k-means longitudinal, we identified women with similar patterns of antidepressant exposure, that is, trajectory groups, during the first 20 and 35 gestational weeks. We estimated risk ratios (RR) and 95% confidence intervals (CI) for the association between trajectory groups and preeclampisa (20-week groups) and PPH (35-week groups), adjusting for demographics, co-morbidities, and other psychotropic medications. Linear trend tests assessing increasing risk of the outcomes across groups were performed.

RESULTS

Among 15 041 (6.6%) pregnancies exposed to an antidepressant, the following trajectory groups were identified: A-low exposure, starting pregnancy at ~10 mg/d, with 1st trimester reduction/discontinuation, B-low sustained exposure of ~20 mg/d, C-moderate exposure (~40 mg/d) with 1st trimester reduction/discontinuation, D-moderate sustained exposure of ~40 mg/d, and E-high sustained exposure of ~75 mg/d. In the low exposure with reduction/discontinuation trajectory, risks were 8.2% for preeclampsia and 2.7% for PPH. Compared with this group, low, moderate, and high sustained trajectories were associated with preeclampsia (adjusted RR 1.17, 95% CI 1.01, 1.34; RR 1.31, 95% CI 1.12, 1.54; and RR 1.41, 95% CI 1.05, 1.90, respectively) and PPH (RR 1.32, 95% CI 1.05, 1.66; RR 1.35, 95% CI 1.03, 1.78; RR 2.51, 95% CI 1.69, 3.71, respectively); P < .01 for linear trend tests for both outcomes. There was no increased risk for either outcome for moderate exposure with reduction/discontinuation (trajectory C).

CONCLUSIONS

Women with sustained antidepressant exposure, especially at higher doses, were at increased risk for preeclampsia and PPH, but underlying depression and anxiety may contribute to the increased risk.

Trajectories of antidepressant drugs during pregnancy: A cohort study from a community-based sample

AIMS

The aim of this study was to monitor the trajectories of antidepressant use during pregnancy and the postpartum period among women chronically treated with antidepressants before their pregnancy, and to assess characteristics associated with each trajectory.

METHODS

This cohort study included all pregnant women whose data were included in the General Sample of Beneficiaries (EGB) database affiliated with the French Health Insurance System, from 2009 to 2014. Women were followed up until 6 months after childbirth. Chronic treatment was defined as exposure over the 6-month period preceding pregnancy. A group-based trajectory model (GBMT) was estimated to identify distinctive longitudinal profiles of antidepressant use.

RESULTS

Among 760 women chronically treated with antidepressants before their pregnancy, 55.8% stopped their treatment permanently in the first trimester, 20.4% discontinued it for a minimum of 3 months and resumed it postpartum, and 23.8% maintained it throughout pregnancy and postpartum. No sociodemographic or medical characteristics were associated with any trajectory group. Women who maintained treatment presented more frequent obstetric complications and postpartum psychiatric disorders. Among women who interrupted treatment, prescription of benzodiazepines and anxiolytics decreased initially but rose postpartum to a higher level than before pregnancy.

CONCLUSIONS

Pregnant women treated with antidepressant require a re-evaluation of psychiatric treatment. It is necessary to pay attention to obstetric complications for severely depressed women. Additionally, as relapse was associated with increased benzodiazepine use, it is important to carefully monitor all women who stop antidepressant treatment during pregnancy.

Efficacy of five-element music interventions in perinatal mental health and labor pain: A meta-analysis

OBJECTIVE

To systematically review the efficacy of five-element music interventions in perinatal mental health and labor pain. To provide evidence for future research on Chinese Traditional Music Interventions.

METHODS

An electronically search was conducted in Web of Science, PubMed, EMbase, The Cochrane Library, CNKI databases, WanFang Data and VIP Database for Chinese Technical Periodicals from inception to January 07, 2020 to collect randomized controlled trials (RCTs) on five-element music interventions for prenatal, perinatal and postpartum women. Literature screening, data extraction, and the risk of bias assessment of all eligible studies were conducted by two reviewers independently. Then, meta-analysis was performed by RevMan 5.3 software.

RESULTS

A total of 13 RCTs involving 2387 patients were included. The results of meta-analysis showed that five-element music could significantly improve the depression levels (SMD = -2.03, 95%CI: -2.88 to -1.19, P < 0.00001), anxiety levels (SMD = -3.49, 95%CI: -4.47 to -2.24, P < 0.00001) and severe anxiety rate (OR = 0.42, 95%CI: 0.19 to 0.94, P = 0.04) of perinatal women. Additionally, five-element music produced significant effects on labor pain (MD = -0.67, 95%CI: -0.82 to -0.52, P < 0.00001), labor duration (MD = -0.85, 95%CI: -1.07 to -0.63, P < 0.00001), the hemorrhage 2 h after parturition (MD = -19.55, 95%CI: -35.56 to -3.54, P = 0.02) and the Serum DYN expression level (MD = 1.32, 95%CI: 0.23 to 2.40, P = 0.02).

CONCLUSIONS

Five-element music may be efficacious in improving perinatal women' depression, anxiety, labor pain, labor duration, the hemorrhage 2 h after parturition and the Serum DYN expression level. Because of the limitation of quantity and quality of included studies, more high-quality studies were needed to confirm the above conclusion.

The mother, the infant and the mother-infant relationship: What is the impact of antidepressant medication in pregnancy

BACKGROUND

Both antidepressant use and depression in pregnancy have the potential to impact on outcomes for the women, their mother-infant relationship and their infants.

METHODS

Data were obtained from 485 pregnant women within Mercy Pregnancy and Emotional Wellbeing Study, a pregnancy cohort study. The sampling frame was in three groups: those depressed women taking antidepressants in pregnancy, women with diagnosed depression not taking an antidepressant and control women. Depression was measured using the Structured Clinical Interview for DSM-IV and repeat Edinburgh Postnatal Depression Scale and antidepressant use by repeat self-report, hospital records and blood levels. In addition, data on key maternal, parenting and infant outcomes were collected.

RESULTS

This study found, for women taking SNRI antidepressant medication there was an elevated rate of pregnancy hypertension. Infants exposed to antidepressants had lower Apgar scores and higher birth weight and this was not associated with dose or class of antidepressant. In contrast, women with higher depressive symptoms had lower maternal antenatal attachment and higher postpartum parenting stress. Both women with depression and those taking antidepressants were less likely to initiate breastfeeding. On the Ages and Stages Questionnaire, there was a significant difference in communication skills in SSRI antidepressant exposed infants at 12 months.

LIMITATIONS

Individual antidepressants could not be examined and development was only measured to 12 months CONCLUSIONS: Overall, the study identified that antidepressant treatment in pregnancy was significantly associated with only a limited number of poorer maternal and infant outcomes and was not associated with poorer parenting outcomes.

Prevalence of benzodiazepines and benzodiazepine-related drugs exposure before, during and after pregnancy: A systematic review and meta-analysis

BACKGROUND

Maternal use of benzodiazepines during pregnancy is common and has increased over the last decades. In this systematic review and meta-analysis, we studied the literature to estimate the worldwide use of benzodiazepines before, during and after pregnancy, which could help to estimate benzodiazepine exposure and to prioritize and guide future investigations.

METHODS

We systematically searched Embase, Medline Ovid, Web of Science and Cochrane Central up until July 2019 for studies reporting on benzodiazepine use before (12 months), during and after pregnancy (12 months). Random effects meta-analysis was conducted to calculate pooled prevalence estimates, as well as stratified according to substantive variables.

RESULTS

We identified 32 studies reporting on 28 countries, together reporting on 7,343,571 pregnancies. The worldwide prevalence of benzodiazepine use/prescriptions during pregnancy was 1.9% (95%CI 1.6%-2.2%; I² 97.48%). Highest prevalence was found in the third trimester (3.1%; 95%CI 1.8%-4.5%; I² 99.83%). Lorazepam was the most frequently used/prescribed benzodiazepine (1.5%; 95%CI 0.5%-2.5%; I² 99.87%). Highest prevalence was found in Eastern Europe (14.0%; 95%CI 12.1%-15.9%; I² 0.00%).

LIMITATIONS

All analyses revealed considerable heterogeneity.

CONCLUSIONS

Our meta-analysis confirmed that benzodiazepine use before, during and after pregnancy is prevalent. The relatively common use of benzodiazepines with possible risks for both mother and (unborn) child is worrying and calls for prescription guidelines for women, starting in the preconception period. Given the substantial proportion of children exposed to benzodiazepines in utero, future research should continue to study the short- and long-term safety of maternal benzodiazepine use during pregnancy and to explore non-pharmacological alternative treatments.

Associations between pre-pregnancy body mass index and gestational weight gain with pregnancy outcomes in women with polycystic ovary syndrome

BACKGROUND

The influence of pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) on perinatal outcomes of women with polycystic ovary syndrome (PCOS) remains unclear. Therefore, we explored how the above indicators influence pregnancy outcomes in women with PCOS.

METHODS

A retrospective study was conducted involving the baseline characteristics, laboratory data, and pregnancy outcomes of 722 pregnant women with PCOS. Subjects were grouped in a way to find out risks in their pregnancy outcomes. Multivariable logistic regression analysis was performed to investigate how BMI and GWG were associated with perinatal outcomes.

RESULTS

Among women with PCOS, underweight increased the risk of small for gestational age (SGA) (OR 12.35, 95% CI 3.56-42.82), but reduced the risk of large for gestational age (LGA). Overweight but not obese women were more susceptible to developing preeclampsia (PE) than women with normal weight. In PCOS women with BMI < 25 kg/m² before pregnancy, inadequate GWG was a protective factor for gestational hypertension (GH) and postpartum hemorrhage (PPH), excessive GWG exhibited a positive correlation with LGA. But in PCOS women with BMI ≥ 25 kg/m², excessive GWG increased the probability of undergoing a cesarean section. Inadequate GWG did not reduce the likelihood of LGA in women with BMI ≥ 25 kg/m², and excessive GWG did not reduce the probability of SGA in women with BMI < 25 kg/m².

CONCLUSION

The impacts of pre-pregnancy BMI, GWG on maternal and infant outcomes among PCOS women are similar to reported results in general pregnant women. However, some unique trends were also observed in PCOS women. While the underweight factor significantly increased the risk of SGA birth, overweight but not obesity was correlated with the risk of PE. Inadequate GWG was a protective factor for GH and PPH only in women with pregestational BMI < 25 kg/m². Inadequate GWG did not reduce the probability of LGA in women with BMI ≥ 25 kg/m², and similarly, excessive GWG did not reduce the probability of SGA in women with BMI < 25 kg/m². Overall, these findings indicate that women with PCOS should begin weight management before pregnancy.

Association of Maternal Weight and Gestational Weight Gain with Maternal and Neonate Outcomes: A Prospective Cohort Study

We investigated the association of outcomes with pre-pregnancy body mass index (ppBMI), Institute of Medicine (IOM) recommendations about gestational weight gain, and weight gain trajectories during pregnancy. A prospective cohort of 7866 pregnant women was recruited. ppBMI and weight gain at each follow up visit were collected. The outcomes were gestational diabetes mellitus (GDM), hypertensive disorders of pregnancy (HDP), caesarean delivery, macrosomia, small (SGA) and large (LGA) for gestational age, neonatal hypoglycemia. Group-based multi-trajectory modelling was used for weight kinetics during pregnancy. In the third trimester, 53.8% of women were above IOM recommendations, with an increased relative risk (RR) of HDP (1.91 (1.40-2.61)), caesarean (1.34 (1.15-1.56)), macrosomia (2.17 (1.77-2.67)), LGA (2.26 (1.83-2.80)), and hypoglycemia (1.89 (1.12-3.18)). Women with a weight gain above IOM recommendations in the second trimester who normalized their weight gain in third trimester had, compared to those who remained above IOM recommendations, fewer events of HDP (2.8% versus 5.3%, p = 0.008), caesarean delivery (16.9% versus 22%, p = 0.006), macrosomia (8.3% versus 14.2%, p < 0.001), and LGA (7% versus 13.2%, p < 0.001). Multi-trajectory modelling identified three profiles with continued variation in RR of complications, including GDM. Weight gain above IOM recommendations increased the risk of perinatal complications. A correction of excessive weight gain in the second trimester reduces these risks.

Transcranial Magnetic Stimulation for Major Depressive Disorder in Pregnancy: A Literature Review

Major depressive disorder (MDD) is a growing problem among pregnant women as current treatment with antidepressants pose significant risks to the mother and fetus. Transcranial magnetic stimulation (TMS) is a neuromodulation technique that is being increasingly utilized to treat MDD in adults. We conducted a literature search using the keyword “TMS” and cross-referencing it with MDD, depression, major depressive episode, pregnancy, efficacy, safety, and clinical trial. This review explores current studies conducted to evaluate the efficacy and safety of TMS to treat MDD in pregnant females. Low-frequency TMS over the right dorsolateral prefrontal cortex, when given to pregnant women with MDD during the second and third trimester, has shown a significant response in depressive symptom reduction. TMS offers a promising alternative to current treatment options for managing MDD during pregnancy, but with limited research available, its safety and efficacy still need to be studied by conducting multicenter trials and long-term studies.
