The Effects of opioids on female fertility, pregnancy and the breastfeeding mother-infant dyad: A Review

Pregnancy Rates Among Women Treated with Medication for Opioid Use Disorder

BACKGROUND

Treatment-seeking people with opioid use disorder (OUD) who are capable of pregnancy need accurate information about the potential impact of medication to treat OUD (MOUD) on fertility to make informed choices about treatment that are consistent with their reproductive wishes. There is a dearth of research on fertility associated with MOUD receipt in birthing people with OUD.

OBJECTIVE

To estimate the association between treatment with MOUD and odds of conception among birthing people using national administrative claims.

DESIGN

Retrospective case-crossover study using multi-state US administrative data (2006-2016). Dates of conception were estimated from delivery dates and served as "case" days for which MOUD exposures were compared to those on all other ("control") days of insurance enrollment.

PARTICIPANTS

Treatment-seeking people with OUD with a delivery during the observation period.

MAIN MEASURES

Odds ratios for conception from within-person fixed effects models were modeled as a function of exposure to MOUD (buprenorphine, methadone, extended-release depot naltrexone, or oral naltrexone) using conditional logistic regression.

KEY RESULTS

A total of 21,928 births among 19,133 people with OUD were identified. In the sample, 5873 people received buprenorphine, 1825 methadone, 486 extended-release naltrexone, and 714 oral naltrexone. Participants could receive more than one type of MOUD. Mean age was 28.2 years (SD = 2.2; range = 16-45), with 76.2% having Medicaid. vs. commercial insurance. Compared to no MOUD, periods of methadone (aOR = 0.55 [95% CI = 0.48-0.63]) or buprenorphine receipt (aOR = 0.84 [0.77-0.91]) were associated with fewer conceptions. Treatment periods with extended-release depot naltrexone compared to no medication were associated with higher odds of conception (aOR = 1.75 [1.22-2.50]) and there was no significant difference in conception with oral naltrexone (aOR = 1.02 [0.67-1.54]).

CONCLUSIONS

The association between MOUD and odds of conception among birthing people varied by type of MOUD, with extended-release naltrexone associated with higher odds of conceiving compared to no treatment. Clinical studies are urgently needed to investigate these findings further.

Simplified processing and rapid quantification of buprenorphine, norbuprenorphine, and their conjugated metabolites in human plasma using UPLC-MS/MS: Assessment of buprenorphine exposure during opioid use disorder treatment

Opioid use disorder (OUD) is a chronic neurobehavioral ailment and is prevalent in pregnancy. OUD is commonly treated with methadone or buprenorphine (BUP). Pregnancy is known to alter the pharmacokinetics of drugs and may lead to changes in drug exposure and response. A simple, specific, and sensitive analytical method for measuring the parent drug and its metabolites is valuable for assessing the impact of pregnancy on drug exposure. A new liquid chromatography-tandem mass spectrometric method that utilized a simple protein precipitation procedure for sample preparation and four deuterated internal standards for quantification was developed and validated for BUP and its major metabolites (norbuprenorphine [NBUP], buprenorphine-glucuronide [BUP-G], and norbuprenorphine-glucuronide [NBUP-G]) in human plasma. The standard curve was linear over the concentration range of 0.05-100 ng/mL for BUP and NBUP, and 0.1-200 ng/mL for BUP-G and NBUP-G. Intra- and inter-day bias and precision were within ±15% of nominal values for all the analytes. Quality controls assessed at four levels showed high recovery consistently for all the analytes with minimal matrix effect. Adequate analyte stability was observed at various laboratory conditions tested. Overall, the developed method is simple, sensitive, accurate and reproducible, and was successfully applied for the quantification of BUP and its metabolites in plasma samples collected from pregnant women in a clinical study assessing BUP exposure during OUD treatment.

Screening Incarcerated Women for Opioid Use Disorder

The overall aim of the present study is to examine the utility of the DSM OUD Checklist and the NM-ASSIST screening tools to identify symptoms consistent with OUD among incarcerated women in county jails. This study contributes to the existing literature because research on screening and assessment approaches for incarcerated women has been limited. The focus of the current study is to describe the screening procedures and study recruitment for a larger parent study focused on increasing treatment linkages. Study findings indicate a positive correlation between indicators of OUD using the two screening tools, as well as a high degree of correlation between street opioid misuse and other high-risk drug indicators (overdose and injection practices). These findings underscore the importance of outreach, screening, and intervention in real-world settings, including jails, in order to increase access to OUD treatment among this vulnerable sample of women.

Endocrine factors associated with infertility in women: an updated review

INTRODUCTION

Infertility is defined as the inability to conceive after unprotected sexual intercourse for at least 12 consecutive months. Our objective is to present an updated narrative review on the endocrine causes of infertility in women.

AREAS COVERED

A comprehensive review was conducted using Scielo, Scopus, and EMBASE databases, comprising 245 articles. The pathophysiology of infertility in women was described, including endocrinopathies such as hypothalamic amenorrhea, hyperprolactinemia, polycystic ovary syndrome, primary ovarian insufficiency, obesity, thyroid dysfunction, and adrenal disorders. The diagnostic approach was outlined, emphasizing the necessity of hormonal studies and ovarian response assessments. Additionally, the treatment plan was presented, commencing with non-pharmacological interventions, encompassing the adoption of a Mediterranean diet, vitamin supplementation, moderate exercise, and maintaining a healthy weight. Subsequently, pharmacological treatment was discussed, focusing on the management of associated endocrine disorders and ovulatory dysfunction.

EXPERT OPINION

This comprehensive review highlights the impact of endocrine disorders on fertility in women, providing diagnostic and therapeutic algorithms. Despite remaining knowledge gaps that hinder more effective treatments, ongoing research and advancements show promise for improved fertility success rates within the next five years. Enhanced comprehension of the pathophysiology behind endocrine causes and the progress in genetic research will facilitate the delivery of personalized treatments, thus enhancing fertility rates.

Sex- and Gender-Specific Drug Abuse Dynamics: The Need for Tailored Therapeutic Approaches

Sex and gender have been gaining ever greater attention due to their associated risks, dynamics, patterns and protective factors underlying substance abuse and addiction. Such differentiations and the clarification of complexities thereof take on even greater relevance in light of drug abuse scope worldwide. According to the 2022 World Drug Report released by the United Nations Office on Drugs and Crime (UNODC), in 2020 an estimated 284 million people worldwide aged 15-64 had used a drug within the last 12 months. The authors have set out to shed a light on determinants and contributing factors of drug abuse based on sex and gender and outline policy and medicolegal remarks aimed at delineating sex- and gender-based approaches towards drug abuse therapeutic interventions that are both therapeutically and ethically/legally viable and grounded in an evidence-based set of standards. Neurobiological data suggest that estrogen may facilitate drug taking by interacting with reward- and stress-related systems. In animal research, the administration of estrogen increases drug taking and facilitates the acquisition, escalation, and reinstatement of cocaine-seeking behavior. From a medicolegal perspective, it is of utmost importance to take into account the whole picture constituting each patient profile, which certainly includes gender factors and contributors, when outlining a therapeutic approach. Failure to do so could lead to negligence-based malpractice allegations, in light of the scientific findings representing best practices with which clinicians need to comply when caring for SUD patients.

Effect of IMB Model Combined with Spousal Support Breastfeeding Intervention on PBSES Score and Breastfeeding Rate of Primipara with Chronic Hepatitis B Virus Infection

Objective

To analyze the effects of the info-motivation-behavior skills (IMB) model combined with spousal support breastfeeding intervention on breastfeeding Self-Efficacy Scale (PBSES) scores and breastfeeding rate of primiparas with chronic hepatitis B virus (HBV) infection.

Methods

Seventy-four first-term pregnant women and 74 of their spouses were selected as the traditional control group by the convenience sampling method from July to September 2021 in obstetrics department of Shenzhen Third People's Hospital. 74 pregnant women with their first child and 74 spouses who had their first child checked during October to December 2021 were classified as the IMB model group. The traditional control group was applied with conventional intervention management mode, and the IMB model group was applied with intervention management mode based on IMB theory on the basis of the traditional control group. The self-efficacy scores of breastfeeding before and after intervention during pregnancy and during hospitalization were compared between the two groups, and the self-efficacy scores of paternal support for breastfeeding were compared. The exclusive breastfeeding rate of infants within 6 months and the maternal breastfeeding knowledge level of the two groups were compared, and the correlation between maternal breastfeeding self-efficacy score and feeding knowledge level was analyzed.

Results

After pregnancy intervention, PBSES and FBSES-SF scores were significantly increased in both groups, and scores of scales in the IMB model group increased significantly than the traditional control group (all P < 0.05). The BSES-SF and FBSES-SF scores of the IMB model group increased significantly than the traditional control group at 3 days after delivery and at discharge (P < 0.05), and the scores of each scale at discharge in both groups increased significantly than those at 3 days after delivery (P < 0.05). The rate of exclusive breastfeeding in the IMB model group was 94.59% (70/74), and that in the traditional control group was 78.38% (58/74). There was a significant difference (χ2 = 8.325, P = 0.004). At discharge, the score of maternal breastfeeding knowledge increased significantly in both groups, and the score of the IMB model group increased significantly than that of the traditional control group (all P < 0.05). Pearson correlation coefficient was used to analyze the correlation between PBSES score, FBSES-SF score, and maternal feeding knowledge level, which showed positive correlation (all P < 0.05).

Conclusion

The self-efficacy of prenatal breastfeeding in pregnant women with HBV is low, and the application of the IMB model combined with the intervention mode of spy-supported breastfeeding has positive effects on the improvement of maternal breastfeeding efficiency, breastfeeding health knowledge level, and postpartum breastfeeding rate, which is worthy of clinical promotion and application.

Opioids and pituitary function: expert opinion

PURPOSE

Opioids are highly addictive potent analgesics and anti-allodynics whose use has dramatically increased in recent decades. The precipitous rise in opioid dependency and opioid use disorder is an important public health challenge given the risks for severely adverse health outcomes. The long-term opioid impact on hypothalamic-pituitary axes is particularly underappreciated among both endocrinologists and primary care physicians. We review the effects of opioids on hypothalamic-pituitary-target gland function and their implications for clinical practice.

METHODS

Experts in hypothalamic-pituitary disorders and opioid pharmacology reviewed recently published literature and considered strategies for diagnosing and managing these opioid-induced endocrine effects.

RESULTS

Opioid suppression of hypothalamic-pituitary axes can lead to hypogonadotropic hypogonadism, central adrenal insufficiency, and hyperprolactinemia. These important clinical manifestations are often under-estimated, poorly evaluated, and typically either untreated or not optimally managed. Data on biochemical testing for diagnosis and on the effect of hormone replacement in these patients is limited and prospective randomized controlled studies for guiding clinical practice are lacking.

CONCLUSIONS

Patients should be informed about risks for hypogonadism, adrenal insufficiency, and hyperprolactinemia, and encouraged to report associated symptoms. Based on currently available evidence, we recommend clinical and biochemical evaluation for potential central adrenal insufficiency, central hypogonadism, and/or hyperprolactinemia in patients chronically treated with opioids as well as the use of current expert guidelines for the diagnosis and treatment of these conditions.
