High lifelong relapse rate of psychiatric disorders among women with postpartum psychosis

The phenomenology of postpartum psychosis: preliminary findings from the Massachusetts General Hospital Postpartum Psychosis Project

Postpartum psychosis (PP) is a severe psychiatric disorder-with limited data or consensus on diagnostic criteria and clinical presentation-that affects thousands of people each year. The Massachusetts General Hospital Postpartum Psychosis Project (MGHP3) was established to: 1) describe the phenomenology of PP, and 2) identify genomic and clinical predictors in a large cohort. Results thus far point to a richer understanding of the heterogeneity and complexity of this often-misunderstood illness and its nature over time. Data are collected from those who experienced PP within 6 months of delivery and within the 10 years prior to the MGHP3 interview. Participants provide information via the Mini International Neuropsychiatric Interview for Psychotic Disorders Studies (MINI-PDS), MGHP3© Questionnaire (including assessment of episode onset, duration, symptoms, and treatment received), and other relevant history. This retrospective study uses validated diagnostic tools to evaluate psychiatric history across participants' lifetimes. Descriptive statistics (e.g., median values, frequencies) were conducted to describe the phenomenology of PP. As of November 3, 2022, 248 participants with histories of at least one episode of PP completed the MGHP3 interview. Most participants met criteria for Bipolar I Disorder with psychotic features (71.8%). During PP episode(s), participants reported odd beliefs or delusions (87.6%), persecutory delusions (75.2%), ideas of reference (55.8%), and visual (52.3%) and/or auditory (48.1%) hallucinations. The median time between delivery and symptom onset was 10 days (SD = 43.72). Most participants reported receiving medication (93.0%) and/or psychotherapy (65.9%). This report describes findings regarding the phenomenology of postpartum psychosis among the MGHP3 cohort, the largest cohort with validated PP studied to date. This ongoing effort to refine the phenotype of PP and to delineate underlying genetic determinants of the disorder will contribute to an enhanced understanding of this serious illness. It also underscores areas for further rigorous assessment using other research methods and sets the stage for translational reproductive neuroscience - including ongoing analyses of neuroimaging and genetic data from the MGHP3 cohort.

Development and preliminary validation of the Postpartum Psychotic Experiences Scale (PPES)

Despite the emerging research interest in postpartum psychotic experiences, there is still a lack of measures for specifically measuring this construct. The contribution of this paper is to design and validate a novel self-report measure, the Postpartum Psychotic Experiences Scale (PPES), to screen for attenuated psychotic symptoms during postpartum. This cross-sectional study was conducted from September 2022 until June 2023, enrolling 438 women 4-6 weeks after delivery. Starting from an initial pool of 22 items, both Exploratory Factor Analysis and Confirmatory Factor Analysis suggested that remaining 15 items loaded on one factor (α = 0.95). The PPES showed good convergent validity with the Prodromal Questionnaire-Brief scale (correlations >0.8) and good concurrent validity with postpartum depression and anxiety scales. A PPSE score of 8.5 (sensitivity=85.2%, specificity=78.6%) was defined as the optimal cutoff point. At this cutoff, 47% of participating women were considered at possible risk for postpartum psychosis. This study provides, for the first time, a specific self-report measure to assess postpartum PEs reliably and validly. We hope that the PPES will facilitate routine screening for PEs after childbirth among women who are predisposed to developing postpartum psychosis.

Postpartum Psychosis: The Role of Women's Health Care Providers and the Health Care System

Importance

The postpartum period is a time of high risk for serious psychiatric symptoms and hospitalization. Postpartum psychosis (PPP) is the most severe disorder that emerges during this time, with significant and wide-ranging consequences that can include suicide and infanticide.

Evidence Acquisition

A PubMed, MEDLINE, and PsycINFO search was completed for English-language publications about PPP, including subtopics (eg, infanticide, maternal suicide). Citations in these articles were also reviewed for relevant references.

Results

Although it is clear that the triggering event for PPP is childbirth, the processes by which this occurs are not fully understood, which is a critical need for being able to predict, prevent, and manage PPP. There are risk factors that contribute to PPP, and specific groups of women may be at increased risk (eg, women with bipolar disorder). Many questions and challenges remain related to the phenomenology, nosology, prevention, and treatment of PPP. However, there are changes that women's health care providers and systems can take to improve the care of women at risk of and experiencing PPP.

Results

Of the 1382 articles reviewed, 8 met eligibility criteria, representing 6 distinct cohorts and 726 subjects. Synthetic slings available for review were either tension-free vaginal tape (TVT) or minisling. The vast majority of studies demonstrated similar short- and long-term success rates of AFS and SS procedures utilizing a range of outcome measures. Both AFS and TVT sling had low recurrence rates in short- and long-term follow-up. However, AFS had significantly longer operative time, and longer hospital stay. Bladder perforation, on the other hand, occurred more commonly in TVT sling. Health-related quality-of-life scores, including sexual function, were similar between groups.

Conclusions and Relevance

Postpartum psychosis is a rare but serious condition. However, recovery is possible. Women's health care providers and systems can improve the care by better understanding the needs of women and families, offering patient-centered discussions and options for care, particularly those that promote recovery, minimize risk, and limit the interruption of the maternal-infant bond. Improving the prevention and treatment of PPP can have a broad impact for women, children, and families.

Long-term outcome of postpartum psychosis: a prospective clinical cohort study in 106 women

OBJECTIVE

We aimed to investigate the outcome of postpartum psychosis over a four-year follow-up, and to identify potential clinical markers of mood/psychotic episodes outside of the postpartum period.

METHODS

One hundred and six women with a diagnosis of first-onset mania or psychosis during the postpartum period were included in this prospective longitudinal study. Women were categorized into either (1) recurrence of non-postpartum mood/psychotic episodes or (2) mania/psychosis limited to the postpartum period. We summarize the longitudinal course of the illness per group. We used a logistic regression model to identify clinical predictors of recurrence of mood/psychotic episodes outside of the postpartum period.

RESULTS

Over two thirds of the women included in this study did not have major psychiatric episodes outside of the postpartum period during follow-up. The overall recurrence rate of mood/psychotic episodes outside the postpartum period was ~ 32%. Of these women, most transitioned to a bipolar disorder diagnosis. None of the women fulfilled diagnostic criteria for schizophrenia or schizophreniform disorder. No clinical markers significantly predicted recurrence outside of the postpartum period.

CONCLUSIONS

For the majority of women with first-onset postpartum psychosis, the risk of illness was limited to the period after childbirth. For the remaining women, postpartum psychosis was part of a mood/psychotic disorder with severe non-postpartum recurrence, mainly in the bipolar spectrum. No clinical predictors for risk of severe episodes outside the postpartum period emerged. Our findings add to previous evidence suggesting a fundamental link between postpartum psychosis and bipolar disorder, which may represent two distinct diagnoses within the same spectrum.

Clozapine Efficacy in a Case of Severe Treatment-Resistant Postpartum Psychosis

BACKGROUND

The postpartum period is a difficult time for mother and family. Unfortunately, in some cases, two psychiatric complications may occur: postpartum psychoses (PPP) with a prevalence of 0.2% and a very low incidence of 0.25-0.50 per 1000 deliveries, and post-natal depressions with an incidence of 10 to 20% per 1000 deliveries. The onset of postpartum psychosis is in the first 4 weeks after childbirth with symptoms such as emotional lability, cognitive disorganization, delusional beliefs and hallucinations. It requires hospitalization due to the high risk of suicide and infanticide. The studies reveal that the treatment can include FGAs (first-generation antipsychotics), such as haloperidol, and SGAs (second-generation antipsychotics), such as olanzapine, quetiapine and risperidone. The literature is scarce in what resistant PPP is concerned and no such cases treated with clozapine have been reported, according to our knowledge. The present case report focuses on a female diagnosed with PPP who was treated with clozapine due to the lack of response to adequate dosage of 2 second-generation antipsychotics.

CASE PRESENTATION

We present the case of a 30-year-old primiparous woman on her 3rd day after delivery, admitted in the psychiatric emergency unit for agitation, intrusive thoughts with a content frequently related to the infant, ideas of reference, disorganized speech, bizarre behavior, verbal stereotypes, insomnia and anxiety. Due to lack of response to adequate dosage of 2 second-generation antipsychotics, clozapine was initiated up to 250 mg/day. The symptoms remitted in the next 5 days and the patient was discharged. After discharge, at the patient's request, clozapine was replaced by olanzapine. Visit at 1 year revealed full remission of symptoms.

CONCLUSION

Although data is extremely limited, clozapine has been shown to be effective and safe in a severe case of treatment-resistant PPP.

Recovery from postpartum psychosis: a systematic review and metasynthesis of women's and families' experiences

Postpartum psychosis is a serious disorder that can result in adverse consequences for the mother and baby. It is important that we understand the experiences of women, to develop effective interventions during this critical period. The aim of this systematic review was to conduct a metasynthesis of qualitative research exploring women's experiences of postpartum psychosis and factors involved in recovery from the perspective of women and family members. A comprehensive literature search of five databases was conducted and the findings were appraised and synthesised, following a thematic synthesis approach. Fifteen studies, capturing the views of 103 women and 42 family members, met the inclusion criteria. Four main themes incorporating 13 subthemes were identified following synthesis: (1) Experiencing the unspeakable, (2) Loss and disruption, (3) Realigning old self and new self and the integrative theme of (4) Social context. The findings offer new insight into the unique experience of postpartum psychosis and demonstrate that recovery does not follow a linear path. To improve clinical outcomes, a more integrative and individualised approach is needed which incorporates long-term psychological and psychosocial support, and considers the needs of the family. Further areas for staff training, service development and future research are highlighted.

Rehospitalization of Postpartum Depression and Psychosis After Electroconvulsive Therapy: A Population-Based Study With a Matched Control Group

OBJECTIVES

Electroconvulsive therapy (ECT) is used in some cases of postpartum depression (PPD) and postpartum psychosis (PPP). The risk of relapse for PPD and PPP after ECT is unknown. This study compared the relapse rate after ECT between women who had been treated for PPD and/or PPP and women who had been treated for depression and/or psychosis outside the postpartum period.

METHODS

The Swedish National Quality Register for ECT and the Swedish National Patient Register were used to identify women with PPD and/or PPP who had been treated with ECT within 6 months after delivery. For each case, a control (treated with ECT but not postpartum) patient was also selected. A Kaplan-Meier estimator was used to calculate the relapse rate (defined as rehospitalization or suicide) after ECT. Cox regression was used to identify variables associated with relapse.

RESULTS

A total of 180 patients were included in each group. The proportions of patients who suffered relapse after 6 months, 1 year, and 2 years were 28%, 31%, and 40% for the postpartum group and 39%, 50%, and 55% for the nonpostpartum group. Treatment with benzodiazepines, several previous psychiatric admissions, and the absence of improvement after ECT were associated with relapse.

CONCLUSIONS

The risk of relapse after ECT is lower for patients with PPD and/or PPP than for patients outside the postpartum period, but the risk is nonetheless substantial in both groups.

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.

Perinatal depression and psychosis: an update

About 85% of women experience some type of postpartum mood disturbance. Generally, the symptoms are mild and short-lived, but a minority of women develop depressive illness or sudden psychosis. About half of episodes of apparently postnatal depression start during pregnancy and some seemingly postpartum psychoses start before delivery. Untreated antenatal depression can lead to poor obstetric outcomes, subsequent depression in the mother, and developmental disadvantage and depression later in life in the offspring. In this article we discuss the aetiology of perinatal depression and consider recommended pharmaceutical and psychosocial management of postpartum blues, perinatal depression and postpartum psychosis.

First lifetime psychiatric admission in the postpartum period: A population-based comparison to women with prior psychiatric admission

OBJECTIVES

To better understand women with a first lifetime psychiatric hospitalization in the postpartum period.

METHODS

We included all 1071 postpartum women in Ontario, Canada, with a psychiatric admission in the 1-year postpartum (2007-2012). We compared women with their first lifetime psychiatric admission to those with any prior psychiatric admission on demographic and clinical characteristics and on mental health physician visits, psychiatric emergency department (ED) revisits and psychiatric readmission within 1-year postdischarge.

RESULTS

Compared to women with prior admission, women with a first lifetime admission (n=537, 59%) were less likely to have psychotic disorders (14% vs. 25%) and had shorter lengths of stay (13.6+/-12.7 vs. 18.9+/-27.8days). Women with prior admission were at higher risk for ED revisits (44% vs. 32%, odds ratio=1.63, 95% confidence interval=1.26-2.09) and readmissions (32% vs. 24%, odds ratio=1.82, 95% confidence interval=1.39-2.38) by 1-year postdischarge versus women with first lifetime admission; differences were explained by clinical factors.

CONCLUSIONS

Although women with a first lifetime psychiatric admission postpartum have a favorable clinical course up to 1year after index admission versus women with any prior admission, 25% are readmitted with 1-year postdischarge, underscoring need for attention to this group.

Does infant feeding method impact on maternal mental health?

BACKGROUND

Breastfeeding has been reported to reduce the risk of postpartum anxiety and depression. However, little is known of the effects of breastfeeding on hospital admissions for postpartum mental disorders.

MATERIALS AND METHODS

This is a population-based longitudinal cohort study using linked data. All mothers who gave birth to a live infant between 2007 and 2008 in New South Wales, Australia were followed up for 1 year for hospital admissions with diagnoses of psychiatric and/or substance use disorders.

RESULTS

There were 186,452 women who were reported as giving birth in New South Wales between 2007 and 2008. The "any breastfeeding" rate at the time of discharge was 87.1%. In total, 2,940 mothers were admitted to the hospital with psychiatric diagnoses within 12 months of birth. The first hospital admission for the diagnoses of overall mental illness was 32 days earlier for non-breastfeeding mothers compared with those with full breastfeeding. Mothers who did not breastfeed were more likely to be admitted to the hospital in the first year postpartum for schizophrenia (adjusted relative risk [ARR]=2.0; 95% confidence interval [CI] 1.3, 3.1), bipolar affective disorders (ARR=1.9; 95% CI 1.1, 3.5), and mental illness due to substance use (ARR=1.8; 95% CI 1.3, 2.5) compared with full breastfeeding mothers.

CONCLUSIONS

Breastfeeding is associated with a decrease in the risk of subsequent maternal hospital admissions for schizophrenia, bipolar affective disorders, and mental illness due to substance use, in the first postpartum year.
