Hormonal contraceptive use and depressive symptoms: systematic review and network meta-analysis of randomised trials

Polycystic Ovary Syndrome and Irritable Bowel Syndrome: Is There a Common Pathway?

OBJECTIVE

Little is known about how polycystic ovary syndrome (PCOS) is linked to irritable bowel syndrome (IBS). This study aimed to review the existing literature regarding the association between PCOS or its symptoms and complications with IBS.

METHODS

In this review, studies that investigated the proposed cross-link between features of PCOS and IBS were included. This review collectively focused on recent findings on the mechanism and novel insight regarding the association between IBS and PCOS in future clinical practice. An electronic search of PubMed, Scopus, Epistemonikos, Cochrane Library and Google Scholar was performed. We did not restrict the study setting and publication date.

RESULTS

The existing evidence has not completely answered the question of whether there is an association between PCOS and IBS and vice versa. Six case-control studies (793 women with PCOS and 547 women in the control group) directly assessed the association between PCOS and IBS. The prevalence of IBS among women with PCOS in these studies has ranged from 10% to 52% compared with 5%-50% in control groups. Evidence suggested the common pathways may have contributed to the interaction between IBS and PCOS, including metabolic syndrome, sex hormone fluctuation, dysregulation of neurotransmitters, psychological problems and environmental and lifestyle factors. To date, it is still ambiguous which of the mentioned components largely contributes to the pathogenesis of both.

CONCLUSION

Although limited evidence has shown a higher prevalence of IBS in women with PCOS, there are several potential, direct and common indirect pathways contributing to the development of both IBS and PCOS.

Management of polycystic ovary syndrome must include assessment and treatment of mental health symptoms

Polycystic ovary syndrome (PCOS) is an endocrine disorder with reproductive and metabolic manifestations affecting millions of women worldwide. The health risks associated with PCOS, however, go beyond physical health. Over the past decade, data have emerged demonstrating a high risk of concurrent mental health conditions, specifically depression and anxiety, but extending into other aspects of psychological health, including body image distress, eating disorders, and sexual dysfunction. International surveys suggest physician knowledge about the mental health associations with PCOS is poor and that patients are often dissatisfied regarding counseling-related psychological issues. We performed a review of mental health comorbidities in individuals with PCOS, including depression, anxiety, body image distress, eating disorders, psychosexual dysfunction, and decreased quality of life, as well as evaluated the impact of common PCOS treatments on these conditions. Most meta-analyses in reproductive age women demonstrate increased risks of these conditions, although data are more limited in adolescents and older adults. In addition, the impact of PCOS treatments on these conditions as well as data on first-line treatments in the PCOS population is limited. All providers involved in the multidimensional care of individuals with PCOS should be aware of these mental health risks to provide appropriate screening, counseling and referral options. Future studies should be designed to evaluate targeted treatment for individuals with PCOS.

Contraceptive use in women with mental illness in Soweto, South Africa

Background

The psychosocial and medical implications of unplanned pregnancy in women with mental illness (MI) are vast. International guidelines make clear recommendations about family planning for women with MI, particularly those exposed to known human teratogens; however, there is limited research related to contraceptive usage among women with MI.

Aim

The aim of this study was to investigate the prevalence of consistent contraceptive use and family planning education (FPE) among a population of women of childbearing age with MI.

Setting

This quantitative cross-sectional study was conducted at Chris Hani Baragwanath psychiatric unit in Soweto, South Africa.

Methods

A convenience sample comprising 190 eligible women of childbearing age with MI was employed for the study. The women were invited to participate by means of a structured questionnaire which was administered by the researcher. Clinical information was obtained from the patients' medical records.

Results

Consistent contraceptive usage occurred in 44.7% of participants. Family planning education was low (26.8%). Relationship status was associated with using contraception consistently (p = 0.0229). Teratogen exposure was not associated with either contraceptive use or FPE. Family planning education was not associated with contraceptive use.

Conclusion

Women with MI may have increased risk for unplanned pregnancy if they are not in a relationship because of perceived lack of need for contraception.

Contribution

Family planning education must be prioritised in women with MI, especially among women prescribed teratogenic medication, highlighting the risks associated with unplanned pregnancy.

A randomized trial comparing the 52-mg levonorgestrel system with combination oral contraceptives for treatment of heavy menstrual bleeding

BACKGROUND

The levonorgestrel intrauterine system and combined oral contraceptives are the 2 most commonly used nonsurgical treatments for heavy menstrual bleeding in the United States. However, there are limited data on their relative effectiveness and on their impact on bleeding-specific quality of life.

OBJECTIVE

This study aimed to compare the effectiveness of the 52-mg levonorgestrel intrauterine system with that of combined oral contraceptives for improving quality of life among individuals who self-report heavy menstrual bleeding. We hypothesized that the levonorgestrel intrauterine system would be more effective than combined oral contraceptives at 6 and 12 months after treatment.

STUDY DESIGN

We conducted a pragmatic randomized trial of individuals who self-reported heavy menstrual bleeding. Individuals were eligible if they did not have contraindications to either the levonorgestrel intrauterine system or combined oral contraceptives and were determined to have a nonstructural cause of heavy menstrual bleeding. Eligible and consenting participants were randomly assigned in a 1:1 ratio to receive a 52-mg levonorgestrel intrauterine system or a monophasic 30- or 35-μg ethinyl estradiol-containing combined oral contraceptive. The main outcome was mean change in bleeding-related quality of life, measured by the 20-question Menstrual Bleeding Questionnaire (score range, 0-75) at 6 and 12 months. Differences in group means and confidence intervals for the Menstrual Bleeding Questionnaire score were computed by multivariable linear mixed-effects regression; 24 participants per group were needed to detect a 10-point difference in change in mean Menstrual Bleeding Questionnaire score between individuals treated with the levonorgestrel intrauterine system and those treated with combined oral contraceptives at each follow-up time point.

RESULTS

A total of 62 individuals were randomly assigned to treatment (n=29 allocated to levonorgestrel intrauterine system and n=33 allocated to combined oral contraceptives) and included in the intention-to-treat analyses; 19 of 29 received the levonorgestrel intrauterine system and 31 of 33 received combined oral contraceptives. Eleven percent identified as Black or African American and 44% identified as Hispanic or Latina. Participant characteristics were similar among study groups. Bleeding-related quality of life increased in both study arms, as reflected by a significant decrease in Menstrual Bleeding Questionnaire scores beginning at 6-week follow-up. In the main intention-to-treat analyses (n=62), there were no differences in mean change in Menstrual Bleeding Questionnaire scores at 6 months (difference=-2.5; 95% confidence interval, -10.0 to +5.0) or 12 months (difference=-1.1; 95% confidence interval, -8.7 to +6.5). Findings were similar in the subsets of participants with any follow-up visits (n=52) and who completed all follow-up visits (n=42). In the per-protocol analyses (n=47), a significantly greater decrease in Menstrual Bleeding Questionnaire score was observed in the levonorgestrel intrauterine system arm at 6 months after treatment (difference=-7.0; 95% confidence interval, -13.8 to -0.2) but not at 12 months (difference=-4.8; 95% confidence interval, -11.8 to 2.3) compared with the combined oral contraceptive arm.

CONCLUSION

No differences in change of bleeding-related quality of life were observed between the levonorgestrel intrauterine system and combined oral contraceptives at 6 or 12 months. Patients should be counseled that the levonorgestrel intrauterine system and combined oral contraceptives are both effective options for improving bleeding-related quality of life.

Major depression associated with a levonorgestrel-releasing intrauterine system mimicking frontotemporal dementia: a case report

This case illustrates the adverse cognitive and affective effects associated with the use of an intrauterine hormonal contraceptive, which could be confused with symptoms of early onset dementia. We present a case of a 42-year-old woman diagnosed with seronegative spondyloarthropathy who subsequently developed anxiety and depressive symptoms after the implantation of a Levonorgestrel-Releasing Intrauterine System (LNG-IUS). Three years later, she began to experience memory and attentional failures, refractory pain, and severe depression. The progression of psychiatric symptoms led to a diagnosis of bipolar affective disorder and treatment with antidepressants and anxiolytics. Due to cognitive and psychiatric symptoms, autoimmune encephalitis was considered, but no improvement was shown with treatment. Early onset dementia was suspected, and a brain PET scan revealed frontal lobe hypometabolism. An adverse effect of LNG-IUS was considered; after its removal, mood and cognitive function improvements were observed. This case report emphasizes the importance of considering organic causes of unexplained psychiatric manifestations and highlights the potential impact of hormonal interventions on mental health.

Population-based cohort study of oral contraceptive use and risk of depression

AIM

Research on the effect of oral contraceptive (OC) use on the risk of depression shows inconsistent findings, especially in adult OC users. One possible reason for this inconsistency is the omission of women who discontinue OCs due to adverse mood effects, leading to healthy user bias. To address this issue, we aim to estimate the risk of depression that is associated with the initiation of OCs as well as the effect of OC use on lifetime risk of depression.

METHODS

This is a population-based cohort study based on data from 264,557 women from the UK Biobank. Incidence of depression was addressed via interviews, inpatient hospital or primary care data. The hazard ratio (HR) between OC use and incident depression was estimated by multivariable Cox regression with OC use as a time-varying exposure. To validate causality, we examined familial confounding in 7,354 sibling pairs.

RESULTS

We observed that the first 2 years of OC use were associated with a higher rate of depression compared to never users (HR = 1.71, 95% confidence interval [CI]: 1.55-1.88). Although the risk was not as pronounced beyond the first 2 years, ever OC use was still associated with an increased lifetime risk of depression (HR = 1.05, 95% CI: 1.01-1.09). Previous OC use were associated with a higher rate of depression compared to never users, with adolescent OC users driving the increased hazard (HR = 1.18, 95% CI: 1.12-1.25). No significant association were observed among adult OC users who had previously used OCs (HR = 1.00, 95% CI: 0.95-1.04). Notably, the sibling analysis provided further evidence for a causal effect of OC use on the risk of depression.

CONCLUSIONS

Our findings suggest that the use of OCs, particularly during the first 2 years, increases the risk of depression. Additionally, OC use during adolescence might increase the risk of depression later in life. Our results are consistent with a causal relationship between OC use and depression, as supported by the sibling analysis. This study highlights the importance of considering the healthy user bias as well as family-level confounding in studies of OC use and mental health outcomes. Physicians and patients should be aware of this potential risk when considering OCs, and individualized risk-benefit assessments should be conducted.
