Women with PCOS who undergo IVF: a comprehensive review of therapeutic strategies for successful outcomes.

Polycystic ovarian syndrome (PCOS) is a widespread syndrome that poses unique challenges and constraints to the field of assisted reproductive technology. This condition is the most common cause of anovulation among infertile couples. Debate exists over the best therapeutic course of action when patients with PCOS proceed to IVF. In this review, we evaluate the best-performing and safest methods of IVF preparation, ovarian stimulation, trigger method for maturation of stimulated egg growth, and planning for embryo transfer. Pre-IVF considerations include being aware of individual AMH and vitamin D levels as well as BMI prior to selecting an ovarian stimulation protocol. Numerous supplements such as myo-inositol complement the benefits of lifestyle change and may enhance IVF performance including oocyte yield and pregnancy rate. Concerning stimulation protocols, antagonist cycles with the judicious use of GnRH agonist trigger, pre-treatment with metformin and vitamin D repletion may help mitigate the accompanied risk of ovarian hyperstimulation syndrome (OHSS). Following ovarian stimulation, PCOS patients typically undergo programmed frozen embryo transfer (FET) cycles which are more conducive for women with irregular cycles, but likely carry a higher risk of hypertensive disorders of pregnancy. However, newer stimulated FET protocols using Letrozole may offer improved outcomes. Overall, patients with PCOS require careful individual tailoring of their IVF cycle to achieve optimal results.

Effect of state insurance mandates on racial/ethnic disparities in the utilization and outcomes of donor oocyte-assisted reproductive technologies.

OBJECTIVE: To characterize racial/ethnic disparities in donor oocyte-assisted reproductive technology (ART) nationwide and examine the impact of state insurance mandates on disparities in utilization and outcomes. DESIGN: Retrospective cohort study. SETTING: Donor oocyte ART cycles in the United States (US). PATIENT(S): Women who underwent donor oocyte ART in 2014-2016, as reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System. INTERVENTION(S): Race/ethnicity of oocyte recipients. MAIN OUTCOME MEASURE(S): Live birth through 1 or more donor oocyte ART cycles in 2014-2016 per recipient. RESULT(S): We analyzed 44,033 donor ART cycles performed for 28,157 oocyte recipients, 99.2% (27,919/28,157) of whom were aged 25-54 years. Race/ethnicity data were reported for 61.4% (17,281/28,157) of the recipients. Among recipients aged 25-54 years with race data, 65.8% (11,264/17,128) identified as non-Hispanic White, whereas 58.9% were White among women aged 25-54 in the 2016 US census. In contrast, Black recipients comprised 8.3% of those aged 25-54 years with race data, compared with 13.7% nationwide. Among White recipients, 7.0% (791/11,356) lived in states with donor ART mandates (Massachusetts/New Jersey), compared with 6.5% (93/1,439) of Black recipients, 8.1% (108/1,335) of Hispanic recipients, and 5.8% (184/3,151) of Asian recipients. Black recipients had a higher median age and body mass index and were more likely to have uterine factor infertility. White recipients had the highest cumulative probability of live birth in the nonmandate (64.6%, 6,820/10,565) and mandate (69.5%, 550/791) states, followed by Asian recipients (nonmandate, 63.4% [1,881/2,967]; mandate, 65.2% [120/184]), Hispanic recipients (nonmandate, 60.5% [742/1,227]; mandate, 68.5% [74/108]), and Black recipients (nonmandate, 48.7% [655/1,346]; mandate, 48.4% [45/93]). The multivariable Poisson regression adjusting for donor's age and recipient's age, body mass index, nulliparity, history of recurrent pregnancy loss, diminished ovarian reserve, tubal factor and uterine factor infertility, prior ART treatment, use of preimplantation genetic testing, cumulative number of embryos transferred, use of blastocysts, and frozen-thawed transfers, demonstrated that Black recipients had a lower cumulative probability of a live birth than White recipients (relative risk [RR], 0.82; 95% confidence interval [CI], 0.77-0.87), as were Hispanic recipients (RR, 0.93; 95% CI, 0.89-0.99) and Asian recipients (RR, 0.96; 95% CI, 0.93-0.99). These disparities were not modified by state mandate for donor ART. CONCLUSION(S): State mandates for donor oocyte ART in their current forms are insufficient in decreasing racial/ethnic disparities.

A Bedside Test to Detect the Presence of Embryonic or Fetal Tissue in Vaginal Blood.

OBJECTIVE: To evaluate a rapid bedside test that detects alpha-fetoprotein (AFP) and insulin-like growth factor-binding protein 1 (IGFBP-1) to identify the presence of embryonic or fetal tissue in vaginal blood. METHOD: This was a prospective cohort study. Reproductive-aged individuals were recruited into three groups: a negative control group consisting of nonpregnant individuals undergoing dilation and curettage (D&C) or experiencing vaginal bleeding; a positive control group of individuals with confirmed intrauterine pregnancy undergoing D&C; and the study group of pregnant individuals with first-trimester bleeding. Lateral flow immunoassay strips capable of detecting both AFP and IGFBP-1 were used to test vaginal blood for the presence of embryonic or fetal tissue. RESULTS: Ninety individuals were recruited: 31 in the positive control group, 23 in the negative control group, and 36 in the study group, including 12 individuals with ectopic pregnancies, 16 with active miscarriages, four with threatened miscarriages, and four with complete miscarriages. Vaginal blood from 14 of the 16 individuals with active miscarriages was correctly positive for embryonic or fetal tissue. Vaginal blood from all individuals with ectopic pregnancies, threatened miscarriages, and complete miscarriages was negative for embryonic or fetal tissue. Overall, 45 of 47 individuals with confirmed embryonic or fetal tissue in vaginal blood correctly tested positive using the test strips, a test sensitivity of 95.7% (95% CI 85.5-99.5%). Of the 43 individuals with confirmed absence of embryonic or fetal tissue in their vaginal blood, 42 were correctly negative, a test specificity of 97.7% (95% CI 87.7-99.9%). CONCLUSION: A rapid test strip detecting both AFP and IGFBP-1 can accurately identify the presence of embryonic or fetal tissue in vaginal blood. When positive, this could aid in diagnosing miscarriage and ruling out ectopic pregnancy at the bedside.

Eliminating Hormones With Orally Active Gonadotropin-releasing Hormone Antagonists.

Gonadotropin-releasing hormone (GnRH) analogues have been used in clinical practice for nearly 3 decades. Beginning with GnRH agonists, these agents have been used to treat hormone-dependent disease and to suppress gonadotropin production in assisted reproductive technologies. With the development of GnRH antagonists and especially small-molecule antagonists, our ability to achieve gonadotropin and sex steroid suppression has become increasingly effective and convenient. In this review, we will briefly describe the development of GnRH analogues, review the evolution of orally active small-molecule GnRH antagonists and provide an overview of the expanding role of small-molecule GnRH antagonists in clinical practice.

Disparities in ART Live Birth and Cumulative Live Birth Outcomes for Hispanic and Asian Women Compared to White Non-Hispanic Women.

BACKGROUND: Conflicting disparities have been seen in assisted reproductive technology (ART) outcomes for Hispanic and Asian women compared to white, non-Hispanic (WNH) women. We, therefore, sought to clarify these disparities and calculated cumulative live birth rates (CLBR) for these racial or ethnic groups using the SARTCORS database. METHODS: We performed an analysis of the 2014-2016 SARTCORS database for member clinics doing at least 50 cycles of ART each year. RESULTS: In comparison to cycles in WNH women, cycles in Hispanic and Asian patients were in older (p < 0.001), more nulliparous women, that were less likely to have a history of endometriosis compared WNH women regardless of prior ART status. ART cycles in Hispanic and Asian women, exhibited lower rates of live birth (LB) per cycle start (p < 0.001) compared to cycles in WNH women. Multivariate logistic regression demonstrated that cycles from Hispanic and Asian women were less likely to have a LB and CLBR than white women (OR 0.86; p = 0.004, OR 0.69; p < 0.001, respectively) independent of age, parity, BMI, etiology of infertility, use of ICSI or number of embryos transferred. CONCLUSIONS: Race or ethnicity continues to be an independent prognostic factor for LB and CLBR for ART. Additional analysis of trends among Hispanic and Asian women is warranted to enable addressing disparities in outcomes in ART treatment.

Tofacitinib alters STAT3 signaling and leads to endometriosis lesion regression.

Endometriosis is a widespread gynecologic condition affecting up to 15% of women of reproductive age. The Janus kinase/signal transducer and activator of transcription (JAK/STAT3) pathway is upregulated in endometriosis and is a therapeutic target. Here we sought to determine the effect of Tofacitinib, a JAK inhibitor in widespread clinical use, on JAK/STAT signaling in endometriosis and lesion growth. Endometriosis was surgically induced in C57BL/6 mice using homologous uterine horn transplantation. Lesions were allowed to form over 4 weeks followed by Tofacitinib (10 mg/kg) or vehicle administered by oral gavage over 4 weeks. Tofacitinib treatment in vivo led to endometriosis lesion regression and reduced adhesion burden compared to vehicle treatment. In vitro studies on Ishikawa cells showed that Tofacitinib reduced hypoxia-inducible factor 1α and vascular endothelial growth factor mRNA levels at 12 and 24 h. Western blot analysis showed that Tofacitinib effectively reduced STAT3 phosphorylation in Ishikawa cells and human primary stromal and epithelial cells from eutopic endometrium of patients with and without endometriosis. This study suggests that the inhibition of JAK/STAT signaling using Tofacitinib may be a viable method for the treatment of endometriosis.

Endometriosis is a chronic systemic disease: clinical challenges and novel innovations.

Endometriosis is a common disease affecting 5-10% of women of reproductive age globally. However, despite its prevalence, diagnosis is typically delayed by years, misdiagnosis is common, and delivery of effective therapy is prolonged. Identification and prompt treatment of endometriosis are essential and facilitated by accurate clinical diagnosis. Endometriosis is classically defined as a chronic, gynaecological disease characterised by endometrial-like tissue present outside of the uterus and is thought to arise by retrograde menstruation. However, this description is outdated and no longer reflects the true scope and manifestations of the disease. The clinical presentation is varied, the presence of pelvic lesions is heterogeneous, and the manifestations of the disease outside of the female reproductive tract remain poorly understood. Endometriosis is now considered a systemic disease rather than a disease predominantly affecting the pelvis. Endometriosis affects metabolism in liver and adipose tissue, leads to systemic inflammation, and alters gene expression in the brain that causes pain sensitisation and mood disorders. The full effect of the disease is not fully recognised and goes far beyond the pelvis. Recognition of the full scope of the disease will facilitate clinical diagnosis and allow for more comprehensive treatment than currently available. Progestins and low-dose oral contraceptives are unsuccessful in a third of symptomatic women globally, probably as a result of progesterone resistance. Oral gonadotropin-releasing hormone (GnRH) antagonists constitute an effective and tolerable therapeutic alternative when first-line medications do not work. The development of GnRH antagonists has resulted in oral drugs that have fewer side-effects than other therapies and has allowed for rapid movement between treatments to optimise and personalise endometriosis care. In this Review, we discuss the latest understanding of endometriosis as a systemic disease with multiple manifestations outside the parameters of classic gynaecological disease.

Vertical transmission of coronavirus disease 2019: a systematic review and meta-analysis.

OBJECTIVE: This study aimed to conduct a systematic review of the current literature to determine estimates of vertical transmission of coronavirus disease 2019 based on early RNA detection of severe acute respiratory syndrome coronavirus 2 after birth from various neonatal or fetal sources and neonatal serology. DATA SOURCES: Eligible studies published until May 28, 2020, were retrieved from PubMed, EMBASE, medRxiv, and bioRxiv collection databases. STUDY ELIGIBILITY CRITERIA: This systematic review included cohort studies, case series, and case reports of pregnant women who received a coronavirus disease 2019 diagnosis using severe acute respiratory syndrome coronavirus 2 viral RNA test and had reported data regarding the testing of neonates or fetuses for severe acute respiratory syndrome coronavirus 2 immediately after birth and within 48 hours of birth. A total of 30 eligible case reports describing 43 tested neonates and 38 cohort or case series studies describing 936 tested neonates were included. STUDY APPRAISAL AND SYNTHESIS METHODS: The methodological quality of all included studies was evaluated by a modified version of the Newcastle-Ottawa scale. Quantitative synthesis was performed on cohort or case series studies according to the neonatal biological specimen site to reach pooled proportions of vertical transmission. RESULTS: Our quantitative synthesis revealed that of 936 neonates from mothers with coronavirus disease 2019, 27 neonates had a positive result for severe acute respiratory syndrome coronavirus 2 viral RNA test using nasopharyngeal swab, indicating a pooled proportion of 3.2% (95% confidence interval, 2.2-4.3) for vertical transmission. Of note, the pooled proportion of severe acute respiratory syndrome coronavirus 2 positivity in neonates by nasopharyngeal swab in studies from China was 2.0% (8/397), which was similar to the pooled proportion of 2.7% (14/517) in studies from outside of China. Severe acute respiratory syndrome coronavirus 2 viral RNA testing in neonatal cord blood was positive in 2.9% of samples (1/34), 7.7% of placenta samples (2/26), 0% of amniotic fluid (0/51), 0% of urine samples (0/17), and 9.7% of fecal or rectal swabs (3/31). Neonatal serology was positive in 3 of 82 samples (3.7%) (based on the presence of immunoglobulin M). CONCLUSION: Vertical transmission of severe acute respiratory syndrome coronavirus 2 is possible and seems to occur in a minority of cases of maternal coronavirus disease 2019 infection in the third trimester. The rates of infection are similar to those of other pathogens that cause congenital infections. However, given the paucity of early trimester data, no assessment can yet be made regarding the rates of vertical transmission in early pregnancy and potential risk for consequent fetal morbidity and mortality.

Status of racial disparities between black and white women undergoing assisted reproductive technology in the US.

BACKGROUND: Numerous studies have demonstrated substantial differences in assisted reproductive technology outcomes between black non-Hispanic and white non-Hispanic women. We sought to determine if disparities in assisted reproductive technology outcomes between cycles from black non-Hispanic and white non-Hispanic women have changed and to identify factors that may have influenced change and determine racial differences in cumulative live birth rates. METHODS: This is a retrospective cohort study of the SARTCORS database outcomes for 2014-2016 compared with those previously reported in 2004-2006 and 1999/2000. Patient demographics, etiology of infertility, and cycle outcomes were compared between black non-hispanic and white non-hispanic patients. Categorical values were compared using Chi-squared testing. Continuous variables were compared using t-test. Multiple logistic regression was used to assess confounders. RESULTS: We analyzed 122,721 autologous, fresh, non-donor embryo cycles from 2014 to 2016 of which 13,717 cycles from black and 109,004 cycles from white women. The proportion of cycles from black women increased from 6.5 to 8.4%. Cycles from black women were almost 3 times more likely to have tubal and/or uterine factor and body mass index ≥30 kg/m2. Multivariate logistic regression demonstrated that black women had a lower live birth rate (OR 0.71;P < 0.001) and a lower cumulative live birth rate for their initial cycle (OR 0.64; P < 0.001) independent of age, parity, body mass index, etiology of infertility, ovarian reserve, cycle cancellation, past spontaneous abortions, use of intra-cytoplasmic sperm injection or number of embryos transferred. A lower proportion of cycles in black women were represented among non-mandated states (P < 0.001) and cycles in black women were associated with higher clinical live birth rates in mandated states (P = 0.006). CONCLUSIONS: Disparities in assisted reproductive technology outcomes in the US have persisted for black women over the last 15 years. Limited access to state mandated insurance may be contributory. Race has continued to be an independent prognostic factor for live birth and cumulative live birth rate from assisted reproductive technology in the US.

Ethnicity/Race and Age-Specific Variations of Serum AMH in Women-A Review.

Purpose of Review: In this review, we summarize ethnic/race- and age-related variation in AMH and discuss the underpinnings behind these differences. Recent findings: Anti-mullerian hormone (AMH) has become a widely used method of ovarian reserve testing over the last 15 years. Numerous studies have shown substantial ethnic/race and age-related differences. When compared to age-matched Caucasian women, AMH levels tend to be lower in black and Hispanic women. Chinese women tend to have significantly greater AMH levels prior to age 25 than Caucasian women. When considering subpopulations within ethnicities, at least one study noted lower AMH levels among Maya women compared to other Hispanic women. Age exhibits a positive trend with AMH up until at least 25 years of age with a consistent decline after 34 years of age extending to menopause. Summary: AMH levels are highly variable among ethnicities and race with higher age-matched levels typically seen in Caucasian women. Age does not exhibit a consistent linear relationship with AMH, but a consistent decline is seen starting in the third decade of life and proceeding to menopause.
