Pharmacotherapy of postpartum depression: an update

A novel tool for risk assessment, screening, diagnosis, assessment, and therapy in postpartum depression

Postpartum depression (PPD), as a common condition occurring in women in the postnatal period, is underdiagnosed, seldom identified, and infrequently treated. Undiagnosed PPD can have negative consequences for overall quality-of-life outcomes in the mother, psychological growth of the infant, and bonding between the infant and its mother. However, early diagnosis and prompt treatment of PPD can lead to an improvement in postpartum maternal health and a healthier relationship between the mother and her infant. Additionally, early identification of risk factors in the prenatal and antenatal period can enable preventive treatment and ensure that the expectant or pregnant woman remains free of disease after giving birth. Therefore, we propose a protocol for the risk assessment, screening, diagnosis, assessment, and therapy of postnatal depression (RASDAT). The RASDAT protocol recommends assessment of risk factors for PPD in the perinatal period as well as early diagnosis and treatment in the early-to-mid postpartum period. It also recognizes, for the first time, insomnia and anxiety as important predictors, comorbidities, and poor prognostic factors in postpartum depression. Further studies are necessary to determine the feasibility and applicability of this novel tool, including costs of availing health facilities, burden on the health system, and knowledge, attitudes, and practices among physicians and clinical pharmacists regarding PPD and its resolution.

Pregnancy-related stroke through a neuropsychology lens

Objective: Stroke represents a primary cause of morbidity and mortality in pregnant and postpartum people. While pregnancy-related stroke has drawn increased attention in certain domains of health research (e.g. obstetrics, neurology), neuropsychology has yet to contribute to this literature. Given neuropsychologists' crucial role in stroke evaluation and rehabilitation efforts, our field is poised to offer insights into this important topic. Method: This review presents facts about pregnancy-related stroke most relevant for neuropsychologists, including epidemiology, risk factors, and mechanisms, alongside clinical considerations and open areas of inquiry. Structured in the format of a traditional neuropsychological evaluation, we walk readers through factors to consider in record review, the clinical interview, and providing feedback and recommendations. Conclusions: Pregnancy-related stroke can be associated with marked functional disability and decreased quality of life, and it is notable that prevalence rates are increasing. Presenting at a time when people are experiencing adjustment to a new phase of life, and most commonly affecting women of color and other vulnerable populations, pregnancy-related stroke is a unique condition warranting special attention within the broader stroke discourse. This review aims to serve as a starting point for neuropsychologists to better understand the unique attributes of pregnancy-related stroke through a neuropsychology lens. Beyond that, it aims to promote broader meaningful discussion of neuropsychology's role in women's health.

Increases in benzodiazepine prescribing for postpartum anxiety during COVID-19

PURPOSE

Postpartum mood disorders affect many women following childbirth. Prescribing medication for depression and anxiety is one strategy for the effective treatment of postpartum mood disorders. Left untreated, mothers experiencing these disorders and their infants face increased risks of adverse health outcomes. Little is known about how diagnosis and treatment of postpartum mood disorders changed during COVID-19.

METHODS

We used a retrospective pooled cross-sectional design in a sample of privately-insured postpartum women in U.S. claims data from January 1, 2016 to December 31, 2020. We measured changes in diagnoses of anxiety and depression and changes in prescription fills and days supplied of classes of medications used to treat these conditions (antidepressants, benzodiazepines, and z-drugs). We used ordinary least squares (OLS) regression for each outcome variable during the pre-pandemic period and forecast expected outcomes the observation period. Forecasted and actual values of the outcomes were then compared.

RESULTS

Following the onset of the COVID-19 pandemic in March 2020, diagnoses of depression and anxiety were not significantly higher among privately insured postpartum women in the United States. The proportion of privately-insured postpartum women filling a benzodiazepine prescription increased by 15.2%.

CONCLUSIONS

We find diagnosis of postpartum mood disorders did not increase after the onset of the COVID-19 pandemic, however, fills of benzodiazepines increased among privately-insured postpartum women. Given prior evidence of increased depressive and anxiety symptoms among postpartum women during COVID-19, this suggests increased barriers to appropriate diagnoses and treatment for depression during this period.

Effectiveness of two systems-level interventions to address perinatal depression in obstetric settings (PRISM): an active-controlled cluster-randomised trial

BACKGROUND

Perinatal depression is a common and undertreated condition, with potential deleterious effects on maternal, obstetric, infant, and child outcomes. We aimed to compare the effectiveness of two systems-level interventions in the obstetric setting-the Massachusetts Child Psychiatry Access Program (MCPAP) for Moms and the PRogram In Support of Moms (PRISM)-in improving depression symptoms and participation in mental health treatment among women with perinatal depression.

METHODS

In this cluster-randomised, active-controlled trial, obstetric practices across Massachusetts (USA) were allocated (1:1) via covariate adaptive randomisation to either continue participating in the MCPAP for Moms intervention, a state-wide, population-based programme, or to participate in the PRISM intervention, which involved MCPAP for Moms plus a proactive, multifaceted, obstetric practice-level intervention with intensive implementation support. English-speaking women (aged ≥18 years) who screened positive for depression (Edinburgh Postnatal Depression Scale [EPDS] score ≥10) were recruited from the practices. Patients were followed up at 4-25 weeks of gestation, 32-40 weeks of gestation, 0-3 months postpartum, 5-7 months postpartum, and 11-13 months postpartum via telephone interview. Participants were masked to the intervention; investigators were not masked. The primary outcome was change in depression symptoms (EPDS score) between baseline assessment and 11-13 months postpartum. Analysis was done by intention to treat, fitting generalised linear mixed models adjusting for age, insurance status, education, and race, and accounting for clustering of patients within practices. This trial is registered with ClinicalTrials.gov, NCT02760004.

FINDINGS

Between July 29, 2015, and Sept 20, 2021, ten obstetric practices were recruited and retained; five (50%) practices were randomly allocated to MCPAP for Moms and five (50%) to PRISM. 1265 participants were assessed for eligibility and 312 (24·7%) were recruited, of whom 162 (51·9%) were enrolled in MCPAP for Moms practices and 150 (48·1%) in PRISM practices. Comparing baseline to 11-13 months postpartum, EPDS scores decreased by 4·2 (SD 5·2; p<0·0001) among participants in MCPAP for Moms practices and by 4·3 (SD 4.5; p<0·0001) among those in PRISM practices (estimated difference between groups 0·1 [95% CI -1·2 to 1·4]; p=0·87).

INTERPRETATION

Both the MCPAP for Moms and PRISM interventions were equally effective in improving depression symptoms. This finding is important because the 4-point decrease in EPDS score is clinically significant, and MCPAP for Moms has a lower intensity and greater population-based reach than does PRISM.

The cost-effectiveness of zuranolone versus selective serotonin reuptake inhibitors for the treatment of postpartum depression in the United States

AIMS

The objective of this research is to evaluate the cost-effectiveness of zuranolone, the first oral treatment indicated for postpartum depression (PPD) in adults approved by the United States Food and Drug Administration.

METHODS

Zuranolone and selective serotonin reuptake inhibitor (SSRI) trial-based efficacy was derived from an indirect treatment comparison. Long-term efficacy outcomes were based on a large longitudinal cohort study. Maternal health utility values were derived from trial-based, short-form 6-D responses. Other inputs were derived from literature and economic data from the US Bureau of Labor Statistics. We estimated costs (2023 US dollars) and quality-adjusted life-years (QALYs) for patients with PPD treated with zuranolone (14-day dosing) or SSRIs (chronic dosing). The indirect costs and QALYs of the children and partners were also estimated.

RESULTS

The incremental cost-effectiveness ratio for zuranolone versus SSRIs was $94,741 per QALY gained over an 11-year time horizon. Maternal total direct medical costs averaged $84,318 in the zuranolone arm, compared to $86,365 in the SSRI arm. Zuranolone-treated adults averaged 6.178 QALYs compared to 6.116 QALYs for the SSRI arm. Costs and utilities for the child and partner were also included in the base case. Drug and administration costs for zuranolone averaged $15,902, compared to $30 for SSRIs over the studied time horizon. Results were sensitive to the model time horizon.

LIMITATIONS

As head-to-head trials were not available to permit direct comparison, efficacy inputs were derived from an indirect treatment comparison which can be confounded by cross-trial differences. The data used are reflective of a general PPD population rather than marginalized individuals who may be at a greater risk for adverse PPD outcomes. The model likely excludes unmeasured effects for patient, child, and partner.

CONCLUSIONS

This economic model's results suggest that zuranolone is a more cost-effective therapy compared to SSRIs for treating adults with PPD.

An investigation of knowledge and attitudes towards antidepressants: a cross-sectional survey of Jordan's six medical schools

OBJECTIVE

Depression is Jordan's most ravaging mental illness. Despite the growth of antidepressant use, only a handful of studies examine the factors affecting antidepressant knowledge among healthcare workers or medical students. Therefore, we aimed to explore the knowledge and attitudes towards antidepressants across Jordan's six medical schools.

METHODS

Using a cross-sectional design, we investigated the knowledge and attitudes towards antidepressants through the Drug Attitude Inventory and a literature-validated knowledge domain. Clinical students from Jordan's six medical schools were recruited. Differences in knowledge and attitudes scores were examined by year of study, medical school among other factors. A multivariate linear regression model was utilized to assess predictors of knowledge.

RESULTS

We included a total of 1,234 participants representing Jordan's six major schools of medicine. About 14.9% of participants had a personal history of antidepressant use while 20.5% reported family history of psychiatric disease. The majority of students demonstrated favorable attitudes towards antidepressants (74.1%). Students demonstrated an average understanding of antidepressants' mechanism of action, side effects, but not indications in special populations. Senior medical students, higher GPA, higher family income, personal history of antidepressants, and family history of psychiatric illnesses were associated with significantly higher knowledge scores (all p-values < 0.001). In addition to attitudes scores, the aforementioned were positive predictors of knowledge scores in the multivariate model.

CONCLUSION

Medical students' knowledge towards antidepressants leaves room for significant improvement. Yet, it is evident that significant differences for both attitudes and knowledge exist across medical schools which may indicate a gap in either training or teaching methodology.

A Novel Treatment of Postpartum Depression and Review of Literature

Early-onset postpartum depression has been shown to have a unique neurobiological basis compared to major depressive disorder, implying a need for targeted treatments such as the recent Food and Drug Administration (FDA)-approved brexanolone. In this case report, a woman with a past medical history of major depressive disorder was diagnosed with postpartum depression due to worsening mood with suicidal and homicidal ideations. She was treated with vilazodone and aripiprazole with good effect after consideration of her past medication trials. Her regimen is unique in clinical practice and not reported in current literature for the treatment of postpartum depression. It may represent a safe and effective medication choice, especially in the context of current first-line treatments that have a high treatment failure rate. More research is needed to find treatments that address the unique challenges of postpartum women.

A Systematic Review of the Efficacy of Repetitive Transcranial Magnetic Stimulation Treatment for Women with Postpartum Depression

Transcranial Magnetic Stimulation (TMS) has a strong evidence base for the treatment of major depressive disorder (MDD), however, there is minimal research investigating the treatment of depression within the postpartum period. This systematic review aims to systematically examine the efficacy and safety of TMS when treating postpartum depression (PPD). Databases Ovid Medline, PsycINFO, EMBASE and PubMed were searched from inception to May 2021, to identify peer-reviewed papers assessing the administration of TMS for PPD treatment. Data were systematically extracted and evaluated regarding clinical psychiatric outcomes, social-relational outcomes, neuropsychological testing, and side effects. This systematic review included one randomised controlled trial, two open-label studies, two conference papers, and two case studies, providing data on 60 participants. TMS appears well tolerated, with no reported major adverse side effects. While the studies reported a general reduction in PPD symptoms, the poor quality of the evidence available indicates that TMS for PPD is unable to be currently recommended. However, the substantial evidence for TMS in the treatment of MDD and the differential response to antidepressant medication in PPD indicates that further research into TMS for PPD is warranted.

Postpartum depression and infant development up to 24 months: A nationwide population-based study

AIMS

Postpartum depression (PPD) is the most common complication women experience after delivery. We aimed to examine the association of maternal PPD with delays in child development, in a population-based study, in the first two years of life.

METHODS

A nation-wide population-based historical cohort study in the setting of the Mother and Child Health Clinics in Israel, where infants are routinely evaluated for growth and development. Data were retrieved on 96,623 infants born in 2014-2015 whose mothers had PPD screening. Logistic regressions were used to estimate the associations of PPD with the achievements of developmental milestones, controlling for potential confounders.

RESULTS

PPD was identified in 4,268 mothers (4.7%). PPD was associated with delays in language skills, including the production of voices in dialogue (OR=1.88, 95% CI: 1.41-2.52) and speaking 2-3 words (OR=1.24, 95% CI: 1.13-1.37). PPD was associated with about 1.5 times increased odds of delays in personal-social skills, including reacting to voices (OR=1.43, 95% CI: 1.22-1.67) and pointing to selected objects (OR=1.47 95% CI: 1.10-1.97). Associations were also seen with delays in fine motor and adaptive skills, such as pinching (OR=1.50, 95% CI: 1.20-1.86), and gross motor skills, such as ground crawling (OR=1.36, 95% CI: 1.15-1.60).

CONCLUSIONS

In this population-based large cohort study, PPD as estimated in a national screening program, was associated with delays in early child development, which were shown in all assessed domains. Future studies should confirm our results and intervention programs should be developed to effectively minimize these gaps.

Brexanolone in Postpartum Depression: Post Hoc Analyses to Help Inform Clinical Decision-Making

Background: Brexanolone (BRX) injection was approved by the United States Food and Drug Administration in 2019 for the treatment of adults with postpartum depression (PPD) based on two Phase 3 clinical trials. Materials and Methods: Data from the three trials were combined. PPD-specific 17-item Hamilton Rating Scale for Depression (HAMD-17) group-level minimal important difference (MID) and patient-level meaningful change (meaningful change threshold [MCT]) were estimated and applied to differences in BRX versus placebo (PBO) at hour 60 (primary endpoint) and day 30 (end of trial follow-up). Likelihood of HAMD-17 response and remission and Clinical Global Impression of Improvement (CGI-I) response for BRX versus PBO were assessed at hour 60 and as sustained through day 30 using relative risk. Associated number needed to treat (NNT) and number needed to harm (NNH) values were also estimated. Results: Two-hundred nine patients were included. The average HAMD-17 MID estimate was -2.1; the least-squared mean difference between BRX and PBO exceeded this at hour 60 and day 30. Minimal, moderate, and large MCTs were estimated to be -9, -15, and -20 points, respectively. Significantly more BRX-treated than PBO-treated patients achieved minimal, moderate, and large change (all ps < 0.05) at hour 60 and large meaningful response at day 30 (p < 0.05). BRX-treated patients were more likely to sustain HAMD-17 remission and CGI-I response through day 30 versus PBO. NNTs ranged from 4 to 8, with NNH of 97. Conclusions: BRX provided meaningful changes relative to PBO, rapid (hour 60), and sustained improvements (day 30) in PPD symptoms, low NNT, and large NNH. These results may help inform treatment decision-making. Clinicaltrials.gov registration numbers: NCT02614547, NCT02942004, and NCT02942017.

Brexanolone: A Novel Drug for the Treatment of Postpartum Depression

OBJECTIVES

To review the pharmacology, efficacy, and safety of Brexanolone and define its role in the treatment of postpartum depression.

DATE SOURCES

A MEDLINE/PubMed search was conducted (1980-May 2020) using the following keywords: postpartum depression, antidepressants, pharmacologic therapy, drug therapy, and brexanolone to identify relevant articles.

STUDY SELECTION/DATA EXTRACTION

Literature search was limited to human studies published in the English language. Phase I, II, and III studies evaluating the pharmacology, efficacy, safety of brexanolone for postpartum depression were included. Bibliographies of relevant articles evaluating postpartum depression and treatment were reviewed for additional citations and background information.

DATA SYNTHESIS

Brexanolone is a soluble, proprietary, injectable formulation of allopregnanolone, a neuroactive steroid that modulates neuronal excitability. Allopregnanolone levels increase during pregnancy and decrease substantially after birth. These fluctuations have profound effects on anxiety and depression. Three clinical trials established the efficacy and safety of brexanolone in the treatment of postpartum depression. In all 3 trials, brexanolone had an acceptable safety profile and was well tolerated. The most common adverse effects were loss of consciousness, sedation, dry mouth, headache, dizziness, and flushing. Due to sudden loss of consciousness and excessive sedation, continuous pulse oximetry is recommended.

CONCLUSION

Brexanolone has a novel mechanism of action and appears to be safe and effective for the treatment of moderate to severe postpartum depression. At present, high cost, serious adverse effects, and restricted access may limit its use in clinical practice.

Efficacy and safety of repetitive transcranial magnetic stimulation for peripartum depression: A meta-analysis of randomized controlled trials

This study aims to summarize and systematically review the efficacy and safety of repetitive transcranial magnetic stimulation (rTMS) for women with peripartum depression (PPD). Several databases (Wanfang, CNKI, VIP, CBM, PubMed, Embase, Cochrane Library, PsyINFO, Web of Science, and Clinical trial) were searched from inception until April 12, 2020. In total, ten randomized controlled trials (RCTs) met the eligibility criteria and were included in this systematic review. We calculated the combined effect size (standardized mean difference [SMD] and odds ratio [OR]) for the corresponding effects models. The aggregated result of 10 trials indicated a significant benefit of rTMS on PPD, and the aggregated result of remission showed significantly positive effects of Test group VS. Control group. In terms of treatment adverse effects, the aggregated result showed no statistical significance of headache and dry mouth between the two groups. The results of the meta-analysis suggest that rTMS is an effective and safe intervention for PPD. Owing to poor methodological quality among the included studies, high-quality multicenter RCTs are needed to further verify the effects of this treatment.

Associations between commonly used patient-reported outcome tools in postpartum depression clinical practice and the Hamilton Rating Scale for Depression

The objective of this study is to explore the associations between the patient-reported Edinburgh Postnatal Depression Scale (EPDS) and Patient Health Questionnaire (PHQ)-9 and clinician-reported 17-item Hamilton Depression Rating Scale (HAMD-17) in order to facilitate clinical decision-making. An integrated efficacy dataset of three randomized placebo-controlled trials (NCT02614547, NCT02942004, and NCT02942017) evaluating brexanolone injection, a neuroactive steroid chemically identical to allopregnanolone, in women with postpartum depression was used for this post hoc analysis. Data were pooled across treatment arms. Associations were assessed at day 30 (end-of-trial follow-up). Pearson correlation assessed the relationship between EPDS and PHQ-9 item and total scores and HAMD-17 total score. Cohen's kappa assessed agreement of EPDS remission (score < 10) and PHQ-9 remission (score < 5) with HAMD-17 remission (score ≤ 7). Ordinary least squares (OLS) regression models were used to develop equations estimating HAMD-17 total scores from EPDS and PHQ-9 scores, respectively. The total scores showed large correlations (HAMD-17/EPDS: r = 0.71, p < 0.001; HAMD-17/PHQ-9: r = 0.75, p < 0.001). Individual EPDS and PHQ-9 items significantly correlated (r= 0.35 to 0.67, all p < 0.001) with HAMD-17 total score. EPDS had 79% sensitivity and 67% specificity to detect HAMD-17 remission; corresponding estimates for PHQ-9 were 76% and 78%. OLS models yielded the following equations: HAMD-17 total = 2.66 + (EPDS total × 0.87) and HAMD-17 total = 3.99 + (PHQ-9 total × 0.97). There were large and statistically significant associations between patient-reported outcomes (EPDS, PHQ-9) and clinician-reported outcomes (HAMD-17) as clinical improvements were associated with patient-reported symptom improvement. These results provide tools to help translate clinical trial data to clinical practice, thus aiding shared decision-making for this critical population.

The effects of pre- and post-partum depression on child behavior and psychological development from birth to pre-school age: a protocol for a systematic review and meta-analysis

BACKGROUND

Pre- and post-partum depression is a common mood disorder with detrimental effects on both mother and child. The aim of the proposed review is to summarize evidence related to the effects of both pre- and post-partum depression on child behavior and development from birth to preschool age. In particular, our review will address mutual relations between pre- and post-partum depression in order to determine whether pre- and post-partum depression predict child psychological outcomes independently, whether there is an effect of timing of depression on child outcomes, whether pre- and post-partum depression interact to affect child outcomes, and whether the effect of pre-partum depression is mediated by depression after child's birth.

METHODS

We will include prospective longitudinal studies that report data about the effects of both pre- and post-partum depression on child psychological outcomes as published in peer-reviewed academic journals since January 1998. We will search EMBASE, MEDLINE, PsycARTICLES, PsycINFO, ISI Web of Science, Scopus, and Wiley Online databases to identify original research articles written in English. Two independent reviewers will screen search results in two stages: (i) titles and abstracts and (ii) full text. The first one will extract data into tables, while the latter will verify whether the data extracted are correct. We will assess the risk of bias in the selected studies using the Critical Appraisal Skills Programme (CASP), Cohort Study Checklist. The results of the review will be reported in a narrative form. If there are sufficient data available, a meta-analysis will be conducted using metaSEM package in R.

DISCUSSION

The proposed review will be the first systematic review summarizing the effects of both pre- and post-partum depression on child psychological development and behavior from birth to preschool age. The results of such a review may contribute to a better understanding of mutual relations between pre- and post-partum depression in their effects on child outcomes. They may also shed light on what periods in early human development are most vulnerable to the effects of maternal depression.

Transdermal estradiol for postpartum depression: results from a pilot randomized, double-blind, placebo-controlled study

Postpartum depression (PPD) is a common complication following delivery, though evidence-based treatment options are limited. This study explores the feasibility and efficacy of outpatient PPD treatment with transdermal estradiol (TE). In a pilot, double-blind, placebo-controlled trial, women with PPD were randomized to receive transdermal 17β-estradiol (100 mcg/day) or placebo patch. Over 6 weeks, women completed weekly ratings on the Beck Depression Inventory (BDI), Edinburgh Postnatal Depression Scale (EPDS), and Hamilton Depression Scale (HAM-D). Primary outcome measures were treatment response (> 50% decrease from baseline BDI) and remission (BDI < 10) at 6 weeks, and secondary outcome measures included severity on all scales at weeks 3 and 6. Of 12 recruited women, 6 received TE and 6 received placebo. By week 6, 5 women receiving TE responded to treatment and 4 showed symptom remission, compared to 2 responders and 1 remitter in the placebo group. This difference was not significant (p = 0.24). In a mixed-model of BDI ratings, TE was associated with a 9.2 point decrease at 3 weeks (95%CI - 19.5 to + 1.0, p = 0.074) and a 10.5 point decrease at 6 weeks (95%CI - 21.0-0.0, p = 0.049) compared to placebo, though these differences did not survive multiple comparisons correction. Analogous effects were found for HAM-D but not EPDS scores. Interestingly, no significant difference in plasma estradiol levels existed between groups. We were unable to demonstrate a significant therapeutic benefit of TE compared with placebo in PPD. Although limited by under-recruitment and loss to follow-up, our results suggest TE is a feasible option for outpatient PPD management, with preliminary evidence (based on secondary outcomes) for efficacy. Therapeutic effects may be seen as early as 3 weeks and may not directly depend on peripheral measures of estradiol.

Cost-Effectiveness of Brexanolone Versus Selective Serotonin Reuptake Inhibitors for the Treatment of Postpartum Depression in the United States

BACKGROUND

Brexanolone injection (BRX) was approved by the FDA in 2019 for the treatment of adult patients with postpartum depression (PPD), but its cost-effectiveness has not yet been evaluated.

OBJECTIVE

To estimate the cost-effectiveness of BRX compared with treatment with selective serotonin reuptake inhibitors (SSRIs) for PPD.

METHODS

We projected costs (2018 U.S. dollars) and health (quality-adjusted life-years [QALYs]) for mothers treated with BRX or SSRIs and their children. A health state transition model projected clinical and economic outcomes for mothers based on the Edinburgh Postnatal Depression Scale, from a U.S. payer perspective. The modeled population consisted of adult patients with moderate to severe PPD, similar to BRX clinical trial patients. Short-term efficacy for BRX and SSRIs came from an indirect treatment comparison. Long-term efficacy outcomes over 4 weeks, 11 years (base case), and 18 years were based on results from an 18-year longitudinal study. Maternal health utility values came from analysis of trial-based short-form 6D responses. Other inputs were derived from the literature.

RESULTS

The incremental cost-effectiveness ratio for BRX versus SSRIs was $106,662 per QALY gained over an 11-year time horizon. Drug and administration costs for BRX averaged $38,501, compared with $25 for SSRIs over the studied time horizon. Maternal total direct medical costs averaged $65,908 in the BRX arm, compared with $73,653 in the SSRI arm. BRX-treated women averaged 6.230 QALYs compared with 5.979 QALYs for the SSRI arm. Adding partner costs and utilities in a sensitivity analysis further favored BRX. Results were sensitive to the severity of PPD at baseline and the model time horizon. Probabilistic sensitivity analyses indicated that BRX was cost-effective at the $150,000-per-QALY threshold with 58% probability.

CONCLUSIONS

Analysis using a state transition model showed BRX to be a cost-effective therapy compared with SSRIs for treating women with PPD.

Is Postpartum Depression Different From Depression Occurring Outside of the Perinatal Period? A Review of the Evidence

Whether a major depressive episode occurring in the postpartum period (i.e., postpartum depression [PPD]) is sufficiently distinct from major depressive episodes occurring at other times (i.e., major depressive disorder) to warrant a separate diagnosis is a point of debate with substantial clinical significance. The evidence for and against diagnostic distinction for PPD is reviewed with respect to epidemiology, etiology, and treatment. Overall, evidence that PPD is distinct from major depressive disorder is mixed and is largely affected by how the postpartum period is defined. For depression occurring in the early postpartum period (variably defined, but typically with onset in the first 8 weeks), symptom severity, heritability, and epigenetic data suggest that PPD may be distinct, whereas depression occurring in the later postpartum period may be more similar to major depressive disorder occurring outside of the perinatal period. The clinical significance of this debate is considerable given that PPD, the most common complication of childbirth, is associated with immediate and enduring adverse effects on maternal and offspring morbidity and mortality. Future research investigating the distinctiveness of PPD from major depressive disorder in general should focus on the early postpartum period when the rapid decline in hormones contributes to a withdrawal state, requiring profound adjustments in central nervous system function.

The role of allopregnanolone in depressive-like behaviors: Focus on neurotrophic proteins

Allopregnanolone (3α,5α-tetrahydroprogesterone; pharmaceutical formulation: brexanolone) is a neurosteroid that has recently been approved for the treatment of postpartum depression, promising to fill part of a long-lasting gap in the effectiveness of pharmacotherapies for depressive disorders. In this review, we explore the experimental research that characterized the antidepressant-like effects of allopregnanolone, with a particular focus on the neurotrophic adaptations induced by this neurosteroid in preclinical studies. We demonstrate that there is a consistent decrease in allopregnanolone levels in limbic brain areas in rodents submitted to stress-induced models of depression, such as social isolation and chronic unpredictable stress. Further, both the drug-induced upregulation of allopregnanolone or its direct administration reduce depressive-like behaviors in models such as the forced swim test. The main drugs of interest that upregulate allopregnanolone levels are selective serotonin reuptake inhibitors (SSRIs), which present the neurosteroidogenic property even in lower, non-SSRI doses. Finally, we explore how these antidepressant-like behaviors are related to neurogenesis, particularly in the hippocampus. The protagonist in this mechanism is likely the brain-derived neurotrophic factor (BFNF), which is decreased in animal models of depression and may be restored by the normalization of allopregnanolone levels. The role of an interaction between GABA and the neurotrophic mechanisms needs to be further investigated.

Intravenous brexanolone for postpartum depression: what it is, how well does it work, and will it be used?

Postpartum depression is considered to be a subtype of major depressive disorder that occurs in approximately 10-20% of mothers worldwide. However, in actuality, these numbers are likely underreported due to minimization and the stigma of mental illness. Until recently, there were no approved medications for the treatment of postpartum depression. Allopregnanolone is a naturally occurring neuroactive steroid whose serum levels decline precipitously following childbirth. This hormonal fluctuation has been postulated as playing a role in the pathophysiology of postpartum depression. Brexanolone is the first medication approved by the US Food and Drug Administration for the treatment of postpartum depression. Brexanolone is an intravenous proprietary formulation of allopregnanolone that can be administered to produce stable serum levels comparable with third-trimester concentrations in postpartum mothers. It is hypothesized to modulate neuronal excitability by functioning as an allosteric modulator of γ-aminobutyric acid-A receptors and is administered under monitoring as a 60 h continuous infusion. In this review, we will highlight the results of the clinical trial program, including efficacy and tolerability data. Practical and logistical considerations of brexanolone will be reviewed, as will its potential place in therapy for the treatment of postpartum depression.

Use of Brexanolone for Postpartum Depression

Postpartum depression (PPD) in women is common and adversely affects the mother, infant, and family unit. Treatments include psychotherapy and pharmacotherapy, but not all women experience response or remission, and response might be delayed. A precipitous decrease in allopregnanolone levels and failure of GABA_A receptors to adapt to this change might contribute to PPD. Administered intravenously, brexanolone (BRX) is a solution of allopregnanolone that modulates the GABA_A receptor and restores third-trimester levels, thus allowing for receptor adaptation and symptom improvement. In clinical studies, patients receiving BRX experienced a rapid reduction or remission of depression. Due to the risk for sedation or syncope, it is only available through a national registry, and administration and monitoring must occur in a supervised medical setting. Further studies are needed to explore its long-term efficacy.

Efficacy of rTMS in decreasing postnatal depression symptoms: A systematic review

BACKGROUND

Repetitive Transcranial Magnetic Stimulation (rTMS) has been suggested as an alternative treatment to postnatal depression (PPD).

OBJECTIVES

This systematic review aims to examine and summarise evidence on rTMS efficacy in treating depression during the postnatal period.

METHODS

We included randomized and non-randomized, single arm, and case report studies, with active rTMS and theta-burst stimulation, sham rTMS, pharmacotherapy or no treatment as comparators. Participants included women with PPD, who were administered rTMS after delivery and up to 12 months postpartum. The observed outcomes were response rate and acceptability.

RESULTS

rTMS shows promising results, with clinically significant decreases in Edinburgh Postnatal Depression Scale (EPDS) scores at week 4 and an overall low risk of dropout.

LIMITATIONS

The reduced number of reports, the lack of complete datasets and the serious/high risk of bias of the studies warrant cautious interpretations.

CONCLUSIONS AND IMPLICATIONS

Despite the promising results, existing evidence on rTMS efficacy is limited, and questions remain on what the most beneficial stimulation parameters should be. Future multicentre randomized clinical trials are needed to better ascertain the clinical efficacy of rTMS in the treatment of depression in the postpartum period.

Maternal depression treatment in HIV (M-DEPTH): Study protocol for a cluster randomized controlled trial

INTRODUCTION

Over one-third of human immunodeficiency virus (HIV)-infected pregnant women are clinically depressed, increasing the risk of mother-to-child transmission (MTCT) of HIV, as well as negative birth and child development outcomes. This study will evaluate the efficacy and cost-effectiveness of an evidence-based stepped care treatment model for perinatal depression (maternal depression treatment in HIV [M-DEPTH]) to improve adherence to prevention of MTCT care among HIV+ women in Uganda.

METHODS

Eight antenatal care (ANC) clinics in Uganda will be randomized to implement either M-DEPTH (n=4) or usual care (n=4) for perinatal depression among 400 pregnant women (n=50 per clinic) between June 2019 and August 2022. At each site, women who screen positive for potential depression will be enrolled and followed for 18 months post-delivery, assessed in 6-month intervals: baseline, within 1 month of child delivery or pregnancy termination, and months 6, 12, and 18 following delivery. Primary outcomes include adherence to the prevention of mother-to-child transmission (PMTCT) care continuum-including maternal antiretroviral therapy and infant antiretrovial prophylaxis, and maternal virologic suppression; while secondary outcomes will include infant HIV status, post-natal maternal and child health outcomes, and depression treatment uptake and response. Repeated-measures multivariable regression analyses will be conducted to compare outcomes between M-DEPTH and usual care, using 2-tailed tests and an alpha cut-off of P <.05. Using a micro-costing approach, the research team will relate costs to outcomes, examining the incremental cost-effectiveness ration (ICER) of M-DEPTH relative to care as usual.

DISCUSSION

This cluster randomized controlled trial will be one of the first to compare the effects of an evidence-based depression care model versus usual care on adherence to each step of the PMTCT care continuum. If determined to be efficacious and cost-effective, this study will provide a model for integrating depression care into ANC clinics and promoting adherence to PMTCT.

Brexanolone, a neurosteroid antidepressant, vindicates the GABAergic deficit hypothesis of depression and may foster resilience

The GABAergic deficit hypothesis of depression states that a deficit of GABAergic transmission in defined neural circuits is causal for depression. Conversely, an enhancement of GABA transmission, including that triggered by selective serotonin reuptake inhibitors or ketamine, has antidepressant effects. Brexanolone, an intravenous formulation of the endogenous neurosteroid allopregnanolone, showed clinically significant antidepressant activity in postpartum depression. By allosterically enhancing GABA _A receptor function, the antidepressant activity of allopregnanolone is attributed to an increase in GABAergic inhibition. In addition, allopregnanolone may stabilize normal mood by decreasing the activity of stress-responsive dentate granule cells and thereby sustain resilience behavior. Therefore, allopregnanolone may augment and extend its antidepressant activity by fostering resilience. The recent structural resolution of the neurosteroid binding domain of GABA _A receptors will expedite the development of more selective ligands as a potential new class of central nervous system drugs.

Postpartum Depression in Men

Postpartum depression (PPD) is often defined as an episode of major depressive disorder (MDD) occurring soon after the birth of a child. It is frequently reported in mothers but can also occur in fathers. There are no established criteria for PPD in men, although it could present over the course of a year, with symptoms of irritability restricted emotions, and depression. Risk factors include a history of depression in either parent, poverty, and hormonal changes. It might be associated with anxiety disorders and can adversely affect the father, family unit, and developing child. Treatment includes psychotherapy and pharmacotherapy. Clinicians are encouraged to screen for depression in men during the first year postpartum and to offer treatment or treatment referral if depression is present.

Toward a framework for best practices and research guidelines for perinatal depression research

This review article highlights the current state of perinatal depression (PND) research including established standards of care and innovative research in progress. PND can have a significant adverse impact on mother, child, and family; however, to date, wide-scale identification, prevention, and treatment have been limited. PND is heterogenous in presentation with likely multifactorial etiologies for each woman. Challenges in PND research are discussed including a need for universal tools, standardized measures, benchmarks, and best practices. Current examples are reviewed that highlight approaches to novel treatment paradigms and interventions. This includes reviewing epidemiologic studies in PND research, examining the biological underpinnings of PND, and discussing examples from this field and other fields currently developing translational research that spans from bench to bedside. Current and future challenges and opportunities in developing best practices for the treatment of PND are outlined. We also discuss the use of the NIMH Research Domain Criteria approach for PND research and provide recommendations for future directions in PND research collaboration. In conclusion, greater precision in perinatal psychiatry can be possible in the future with the development of guidelines and best practices that build on current work and apply innovative and collaborative approaches of scientists, providers, patients, community members, and government officials.

Mental and physical support (MAPS) for moms: preliminary findings from a prenatal health support program

BACKGROUND

The low incidence of exercise during pregnancy and the high rates of prenatal depression indicate more opportunities are needed for mothers to engage in exercise and obtain health-related support and education. MAPS (mental & physical support) was developed to support mothers' psychological and physical health during pregnancy. MAPS consisted of physical activity classes 2×/week followed by either a speaker or group discussion regarding a parenting or health-related topic. The primary purpose of this study was to determine if the format was feasible prior to developing a main scale randomized trial.

METHODS

Program measurements included a pre/post survey, post-program focus group, attendance logs and scales for exercise, self-efficacy, and social support.

RESULTS

Findings indicated the program format is well-received by participants; however, issues in attendance warrant program format alterations. Further, larger scale studies and the addition of a control group are needed.

CONCLUSION

This format offers practitioners an effective strategy for supporting pregnant women's physical and psychological health.

Using Matching-Adjusted Indirect Comparisons and Network Meta-analyses to Compare Efficacy of Brexanolone Injection with Selective Serotonin Reuptake Inhibitors for Treating Postpartum Depression

BACKGROUND

Brexanolone injection, the first therapy approved by the US FDA for the treatment of postpartum depression (PPD) in adults, has been shown to produce a significantly greater decrease in the Hamilton Rating Scale for Depression (HAM-D) total score than placebo in randomised controlled trials (RCTs) of women with PPD.

OBJECTIVES

Given the rapid effect of brexanolone injection (within 60 h) sustained throughout the length of the trials (30 days), we sought to compare its efficacy data against selective serotonin reuptake inhibitors (SSRIs), the class of antidepressants most commonly prescribed for PPD, using HAM-D and Edinburgh Postnatal Depression Scale (EPDS) outcomes from currently available RCTs.

METHODS

We extracted data from 26 studies identified in a systematic literature review of pharmacological and pharmacological/nonpharmacological combination therapies in PPD. Six studies were suitable to form evidence networks through which to perform indirect treatment comparisons (ITCs) of HAM-D and EPDS outcomes between brexanolone and SSRIs. Having assessed the comparability and suitability of the available evidence for analysis, we discovered significant heterogeneity in the study designs, most notably in the placebo arms of the trials. We therefore conducted matching-adjusted indirect comparisons (MAICs) between brexanolone and the placebo arms of comparator studies, subsequently using the MAIC results of brexanolone versus placebo, and results for SSRIs versus placebo, to form ITCs of brexanolone versus SSRIs at three separate time points-day 3, week 4 and last observation. ITCs were calculated as the differences in change from baseline (CFB) in HAM-D and, separately, CFB in EPDS, between treatments, and reported with 95% confidence intervals (CIs).

RESULTS

For all time points, MAICs showed larger differences in CFB for brexanolone compared with SSRIs. Differences (95% CIs) between brexanolone and SSRIs were 12.79 (8.04-17.53) [day 3], 5.87 (- 1.62 to 13.37) [week 4] and 0.97 (- 6.35 to 8.30) [last observation] for the HAM-D. For the EPDS, the differences in CFB were 7.98 (5.32-10.64) [day 3], 6.35 (3.13-9.57) [week 4] and 4.05 (0.79-7.31) [last observation]. Other analytical approaches are also presented to demonstrate the similarity of results, using a network meta-analysis approach, and the importance of using the MAIC method to control for the important heterogeneity between placebo arms.

CONCLUSIONS

Acknowledging the limitations of ITCs and this evidence base, when compared with SSRIs, these analyses suggest that brexanolone demonstrated larger differences in CFB for both patient- and clinician-reported PPD outcomes and at all investigated time points after adjusting for differences between placebos in the included studies.

Optimized bio-analytical methods development and comparative pharmacokinetic studies of four antidepressants in Egyptian population based on gender difference

The pharmacokinetics (PK) and pharmacodynamics of many oral antidepressants (OADs) vary substantially among different genders and ethnicities. Likewise is their therapeutic effectiveness, time to response and the incidence of adverse drug events. The aim of this study is to compare the PK of four OADs (desvenlafaxine; DSV, venlafaxine; VLX, escitalopram; ESP, and agomelatine; AGT) among Egyptian males and females. In this study, LC-MS/MS methods were developed and validated for determining the four OADs in human plasma. Samples were prepared by liquid-liquid extraction. Chromatographic separation was performed on reversed-phase C₁₈ columns followed by positive-ion electrospray ionization and MS/MS detection. The assays were applied for the assessment of PK parameters in human volunteers (n = 95). The developed methods were linear, accurate, and precise for the determination of DSV, VLX, ESP and AGT with extraction recovery of 90 ± 2.0, 98 ± 1.0, 90 ± 1.3 and 87 ± 4.3%, respectively. OADs levels were successfully measured in subjects' plasma and PK parameters were calculated. A prevalent inter-individual variation in PK of the studied OAD was observed. The PK profile of DSV, VLX or ESP did not vary significantly between male and female subjects (p = 0.07-0.98; confidence level (CL) = 95) while the PK of AGT exhibited a significant gender-based variation in both the C_max and the AUC_∞ (p = 0.047 and 0.0015; CL = 95). Our results highlight the significance of therapeutic drug monitoring of OADs. Further, it indicates the dose adjustment based on gender difference may not be relevant for DSV, VLX and ESP while it may be considered for AGT.

Brexanolone injection in post-partum depression: two multicentre, double-blind, randomised, placebo-controlled, phase 3 trials

BACKGROUND

Post-partum depression is associated with substantial morbidity, and improved pharmacological treatment options are urgently needed. We assessed brexanolone injection (formerly SAGE-547 injection), a positive allosteric modulator of γ-aminobutyric-acid type A (GABA_A) receptors, for the treatment of moderate to severe post-partum depression.

METHODS

We did two double-blind, randomised, placebo-controlled, phase 3 trials, at 30 clinical research centres and specialised psychiatric units in the USA. Eligible women were aged 18-45 years, 6 months post partum or less at screening, with post-partum depression and a qualifying 17-item Hamilton Rating Scale for Depression (HAM-D) score (≥26 for study 1; 20-25 for study 2). Women with renal failure requiring dialysis, anaemia, known allergy to allopregnanolone or to progesterone, or medical history of schizophrenia, bipolar disorder, or schizoaffective disorder were excluded. Patients were randomly assigned (1:1:1) to receive a single intravenous injection of either brexanolone 90 μg/kg per h (BRX90), brexanolone 60 μg/kg per h (BRX60), or matching placebo for 60 h in study 1, or (1:1) BRX90 or matching placebo for 60 h in study 2. Patients, the study team, site staff, and the principal investigator were masked to treatment allocation. The primary efficacy endpoint was the change from baseline in the 17-item HAM-D total score at 60 h, assessed in all patients who started infusion of study drug or placebo, had a valid HAM-D baseline assessment, and had at least one post-baseline HAM-D assessment. The safety population included all randomised patients who started infusion of study drug or placebo. Patients were followed up until day 30. The trials have been completed and are registered with ClinicalTrials.gov, numbers NCT02942004 (study 1) and NCT02942017 (study 2).

FINDINGS

Participants were enrolled between Aug 1, 2016, and Oct 19, 2017, in study 1, and between July 25, 2016, and Oct 11, 2017, in study 2. We screened 375 women simultaneously across both studies, of whom 138 were randomly assigned to receive either BRX90 (n=45), BRX60 (n=47), or placebo (n=46) in study 1, and 108 were randomly assigned to receive BRX90 (n=54) or placebo (n=54) in study 2. In study 1, at 60 h, the least-squares (LS) mean reduction in HAM-D total score from baseline was 19·5 points (SE 1·2) in the BRX60 group and 17·7 points (1·2) in the BRX90 group compared with 14·0 points (1·1) in the placebo group (difference -5·5 [95% CI -8·8 to -2·2], p=0·0013 for the BRX60 group; -3·7 [95% CI -6·9 to -0·5], p=0·0252 for the BRX90 group). In study 2, at 60 h, the LS mean reduction in HAM-D total score from baseline was 14·6 points (SE 0·8) in the BRX90 group compared with 12·1 points (SE 0·8) for the placebo group (difference -2·5 [95% CI -4·5 to -0·5], p=0·0160). In study 1, 19 patients in the BRX60 group and 22 patients in the BRX90 group had adverse events compared with 22 patients in the placebo group. In study 2, 25 patients in the BRX90 group had adverse events compared with 24 patients in the placebo group. The most common treatment-emergent adverse events in the brexanolone groups were headache (n=7 BRX60 group and n=6 BRX90 group vs n=7 placebo group for study 1; n=9 BRX90 group vs n=6 placebo group for study 2), dizziness (n=6 BRX60 group and n=6 BRX90 group vs n=1 placebo group for study 1; n=5 BRX90 group vs n=4 placebo group for study 2), and somnolence (n=7 BRX60 group and n=2 BRX90 group vs n=3 placebo group for study 1; n=4 BRX90 group vs n=2 placebo group for study 2). In study 1, one patient in the BRX60 group had two serious adverse events (suicidal ideation and intentional overdose attempt during follow-up). In study 2, one patient in the BRX90 group had two serious adverse events (altered state of consciousness and syncope), which were considered to be treatment related.

INTERPRETATION

Administration of brexanolone injection for post-partum depression resulted in significant and clinically meaningful reductions in HAM-D total score at 60 h compared with placebo, with rapid onset of action and durable treatment response during the study period. Our results suggest that brexanolone injection is a novel therapeutic drug for post-partum depression that has the potential to improve treatment options for women with this disorder.

Effectiveness of acupuncture in postpartum depression: a systematic review and meta-analysis

OBJECTIVE

To assess the clinical effectiveness of acupuncture in the treatment of postpartum depression (PPD).

METHODS

The following electronic databases were systematically searched: PubMed, Cochrane Library, SCI, Elsevier SDOL, China National Knowledge, Wan Fang database and Chinese Science and Technology Periodical Database. Only randomised controlled trials (RCTs) of acupuncture for PPD were considered. Primary outcomes were the Hamilton Rating Scale for Depression (HAMD) or the Edinburgh Postnatal Depression Scale (EPDS) scores and effective rate. Our secondary outcome was the level of oestradiol. The quality of all included trials was evaluated according to the Cochrane Collaboration. This protocol was registered in PROSPERO (CRD42016048528).

RESULTS

Nine trials involving 653 women were selected. The result of this meta-analysis demonstrated that the acupuncture group had a significantly greater overall effective rate compared with the control group (seven trials, n=576, I²=24%; relative risk (RR) 1.15, 95% CI 1.06 to 1.24; P<0.001). Moreover, acupuncture significantly increased oestradiol levels compared with the control group (mean difference (MD) 36.92, 95% CI 23.14 to 50.71, P<0.001). Regarding the HAMD and EPDS scores, no difference was found between the two groups (five trials, n=276, I²=82%; MD-1.38, 95% CI -3.40 to 0.64; P=0.18; two trials, n=60, I2=16%; MD 1.08, 95% CI -1.09 to 3.26; P=0.33).

CONCLUSIONS

Acupuncture appears to be effective for postpartum depression with respect to certain outcomes. However, the evidence thus far is inconclusive. Further high-quality RCTs following standardised guidelines with a low risk of bias are needed to confirm the effectiveness of acupuncture for postpartum depression.

The role of tryptophan metabolism in postpartum depression

The Postpartum depression (PPD) is the most common postpartum psychiatric disorder, afflicting approximately 10%-20% of new mothers. Clinical symptoms of the PPD include depressive disorder, agitation, insomnia, anxiety and confusion, resulting in an increase in suicidal tendencies, thereby having significant impacts on the puerpera, newborn and their family. A growing body of data indicate a role for alterations in tryptophan metabolism in the PPD. The metabolism of tryptophan produces an array of crucial factors that can differentially regulate key physiological processes linked to the PPD. Importantly, an increase in stress hormones and immune-inflammatory activity drives tryptophan to the production of neuroregulatory kynurenine pathway products and away from the serotonin and melatonin pathways. This links the PPD to other disorders of depressed mood, which are classically associated with decreased serotonin and melatonin, coupled to increases in kynurenine pathway products. Several kynurenine pathway products, such as kynurenic acid and quinolinic acid, can have neuroregulatory effects, with consequences pathological underpinnings of the PPD. The current article reviews the role of alterations in tryptophan metabolism in the PPD.

Perinatal SSRI medications and offspring hippocampal plasticity: interaction with maternal stress and sex

There is growing use of selective serotonin reuptake inhibitor antidepressant (SSRI) medications during the perinatal period to treat maternal affective disorders. Perinatal SSRI exposure can have a long-term impact on offspring neuroplasticity and behavioral development that remains to be fully elucidated. This mini-review will summarize what is known about the effects of perinatal SSRIs on plasticity in the developing hippocampus, taking into account the role that maternal stress and depression may have. Emerging clinical findings and research in animal models will be discussed. In addition, sexually differentiated effects will be highlighted, as recent work shows that male offspring are often more sensitive to the effects of maternal stress, whereas female offspring can be more sensitive to perinatal SSRIs. Potential mechanisms behind these changes and aims for future research will also be discussed. Understanding the impact of perinatal SSRIs on neuroplasticity will provide better insight into the long-term effects of such medications on the health and well-being of both mother and child and may improve therapeutic approaches for maternal mood disorders during the perinatal period.

Open-label, proof-of-concept study of brexanolone in the treatment of severe postpartum depression

OBJECTIVE

Preclinical evidence indicates that rapid changes in levels of allopregnanolone, the predominant metabolite of progesterone, confer dramatic behavioral changes and may trigger postpartum depression (PPD) in some women. Considering the pathophysiology of PPD (i.e., triggered by reproductive steroids), the need for fast-acting, efficacious treatments and the negative consequences of untreated PPD, there is an increasing focus on developing PPD therapies. Brexanolone (USAN; formerly SAGE-547 Injection), a proprietary injectable allopregnanolone formulation, was evaluated as a treatment for severe PPD in a proof-of-concept, open-label study.

METHODS

Four women with severe PPD, defined as a baseline 17-item Hamilton Rating Scale for Depression (HAMD) score of ≥20, received brexanolone, titrated to a dose reflecting third-trimester allopregnanolone levels. After a 36-hour maintenance infusion, tapering occurred over 12 hours. Primary outcomes were measures of safety. Secondary outcomes were assessments of efficacy, including HAMD.

RESULTS

All enrolled patients completed the study. Fourteen adverse events were reported, of which none was severe. Starting at the first measure after infusion initiation and continuing through Hour 84, mean HAMD total scores were reduced to levels consistent with remission of symptoms. All other efficacy assessments showed similar improvements.

CONCLUSIONS

Brexanolone was well tolerated and demonstrated activity in severe PPD. Larger, double-blind trials are needed for further evaluation.

The Neurobiology of Postpartum Anxiety and Depression

Ten to twenty percent of postpartum women experience anxiety or depressive disorders, which can have detrimental effects on the mother, child, and family. Little is known about the neural correlates of these affective disorders when they occur in mothers, but they do have unique neural profiles during the postpartum period compared with when they occur at other times in a woman's life. Given that the neural systems affected by postpartum anxiety and depression overlap and interact with the systems involved in maternal caregiving behaviors, mother-infant interactions are highly susceptible to disruption. Thus, there is an intricate interplay among maternal mental health, the mother-infant relationship, and the neurobiological mechanisms mediating them that needs to be the focus of future study.

ASSERT trial - How to assess the safety and efficacy of a high frequency rTMS in postpartum depression ? A multicenter, double blinded, randomized, placebo-controlled clinical trial

Background

Postpartum Depression affects a considerable number of women worldwide. This condition inflicts severe consequences to mother and child health. Thus far, available treatments have low response and high relapse rates. We designed this trial to evaluate a safe and more efficacious innovative therapy.

Aims

To report a feasible and ethical study design to assess the safety and efficacy of a high frequency repetitive Transcranial Magnetic Stimulation 10 Hz (rTMS) compared to sham rTMS in women with moderate to severe Post-Partum Depression using standard treatment (sertraline).

To conduct an ancillary, exploratory, randomized, active controlled, double blind study with a hypothesis to assess the safety and efficacy of 10 Hz rTMS compared to sertraline.

Methods

A multicenter, parallel arm, randomized, placebo-controlled, double-blind design to assess safety and efficacy of 10 Hz rTMS compared to sham.

An ancillary study will be conducted with parallel arm, randomized, active controlled and double dummy design to assess safety and efficacy of 10 Hz rTMS compared to sertraline.

Canadian Network for Mood and Anxiety Treatments (CANMAT) 2016 Clinical Guidelines for the Management of Adults with Major Depressive Disorder: Section 6. Special Populations: Youth, Women, and the Elderly

BACKGROUND

The Canadian Network for Mood and Anxiety Treatments (CANMAT) conducted a revision of the 2009 guidelines by updating the evidence and recommendations. The scope of the 2016 guidelines remains the management of major depressive disorder (MDD) in adults, with a target audience of psychiatrists and other mental health professionals.

METHODS

Using the question-answer format, we conducted a systematic literature search focusing on systematic reviews and meta-analyses. Evidence was graded using CANMAT-defined criteria for level of evidence. Recommendations for lines of treatment were based on the quality of evidence and clinical expert consensus. This section on "Special Populations" is the sixth of six guidelines articles.

RESULTS

Recent studies inform the treatment of MDD in children and adolescents, pregnant and breastfeeding women, women in perimenopause or menopause, and the elderly. Evidence for efficacy of treatments in these populations is more limited than for the general adult population, however, and risks of treatment in these groups are often poorly studied and reported.

CONCLUSIONS

Despite the limited evidence base, extant data and clinical experience suggest that each of these special populations can benefit from the systematic application of treatment guidelines for treatment of MDD.

Treatment of severe perinatal mood disorders on a specialized perinatal psychiatry inpatient unit

Perinatal patients with bipolar and psychotic mood disorder exacerbations are challenging to treat and often receive suboptimal care. We sought to examine the treatment patterns and outcomes on one of the only US-based Perinatal Psychiatry Inpatient Units (PPIU). Perinatal patients admitted to the PPIU completed self-report measures at admission and before discharge. Retrospective chart reviews extracted history, diagnoses (current and past), and medication treatment. Patients who had discharge diagnoses of bipolar disorder, major depression with psychotic features, or postpartum psychosis were included. Forty-seven met the diagnostic inclusion criteria. Over an average length of stay (ALOS) of 9.96 days, there was significant improvement in depressive and anxiety symptoms and daily functioning (Work and Social Adjustment Scale). Psychiatric comorbidity was common. Polypharmacy was utilized in 87 %. The most common medications prescribed at discharge were antipsychotics, alone or in combination with mood stabilizers or antidepressants. ECT was performed in 10 % of cases. The complexity of patients with severe mood disorders or psychosis admitted to the PPIU supports individualized treatment plans that address both primary diagnosis and psychiatric comorbidities. Our results provide important information that can be disseminated to others to improve clinical outcomes for severe perinatal mood disorders.

Overcoming functional impairment in postpartum depressed or anxious women: a pilot trial of desvenlafaxine with flexible dosing

OBJECTIVES

Antidepressants are the first line treatment for moderate to severe major depressive disorder (MDD) in perinatal and general populations. However, there appears to be paucity of evidence around antidepressant use in women with postpartum depression or anxiety. Selection of an appropriate antidepressant is crucial in promoting efficacy, optimizing tolerability, and managing comorbid anxiety or depression. Our aim was to investigate the treatment effect and tolerability profile of desvenlafaxine, and to examine the functionality of women with postpartum depression or anxiety after desvenlafaxine treatment.

METHODS

Fifteen postpartum women with depression or anxiety completed this 12-week prospective pilot study with a flexible dose of desvenlafaxine (50-100 mg). Participants were recruited at a tertiary care level program. Measures of depression (Montgomery-Åsberg Depression Rating Scale, MADRS), anxiety (Hamilton Anxiety Rating Scale, HAM-A), worry (Penn State Worry Questionnaire, PSWQ) and functional impairment (Sheehan Disability Scale, SDS) were completed at baseline, 8 weeks, and 12 weeks.

RESULTS

In the intention-to-treat analysis (n = 17), the majority of women responded to medication (88.2%, n = 15), and reached remission of depressive (82.4%, n = 14) and anxiety symptoms (82.4%, n = 14). Remission of depression was achieved in a mean of 6.9 weeks [standard deviation (SD) = 3.01] at a mean dose of 71 mg/day (SD = 25.7). Significant decreases were observed on PSWQ worry scores (p < 0.0001) and SDS scores for social (p < 0.0001) and family life impairment (p < 0.0001). The medication was generally well tolerated.

CONCLUSION

The results of our prospective pilot study suggest that treatment with desvenlafaxine of postpartum mothers with depression or anxiety can lead to symptom remission and restoration of functionality.

Psychiatric consultation to the postpartum mother

The immediate postpartum period is a time of acute vulnerability to mental illness, which presents unique challenges for the psychiatric consultant. Because the postpartum hospital stay is typically brief, the consultant must have a working knowledge of postpartum physiology and the myriad forms of mental illness that may emerge in this vulnerable time, in order to quickly make a diagnosis and formulate a treatment plan. This review aims to characterize the most common reasons for postpartum consultation, review postpartum physiology and psychiatric conditions, and propose an evidence-based, practical approach to treatment. A literature search using the terms "postpartum," "obstetric," "consultation," and "psychiatry" yielded six studies that identified reasons for psychiatric consultation to the obstetrics and gynecology services. These studies informed the structure of the article such that we review the most common reasons for consultation and how to approach each issue. The most common reason for consultation is past psychiatric history, often in the absence of current symptoms. For each clinical situation, including depression, adverse birth events, and psychosis, we present a differential diagnosis, as well as risk factors, clinical signs, and recommended treatment.
