Elagolix for Heavy Menstrual Bleeding in Women with Uterine Fibroids.

BACKGROUND: Uterine fibroids are hormone-responsive neoplasms that are associated with heavy menstrual bleeding. Elagolix, an oral gonadotropin-releasing hormone antagonist resulting in rapid, reversible suppression of ovarian sex hormones, may reduce fibroid-associated bleeding. METHODS: We conducted two identical, double-blind, randomized, placebo-controlled, 6-month phase 3 trials (Elaris Uterine Fibroids 1 and 2 [UF-1 and UF-2]) to evaluate the efficacy and safety of elagolix at a dose of 300 mg twice daily with hormonal "add-back" therapy (to replace reduced levels of endogenous hormones; in this case, estradiol, 1 mg, and norethindrone acetate, 0.5 mg, once daily) in women with fibroid-associated bleeding. An elagolix-alone group was included to assess the impact of add-back therapy on the hypoestrogenic effects of elagolix. The primary end point was menstrual blood loss of less than 80 ml during the final month of treatment and at least a 50% reduction in menstrual blood loss from baseline to the final month; missing data were imputed with the use of multiple imputation. RESULTS: A total of 412 women in UF-1 and 378 women in UF-2 underwent randomization, received elagolix or placebo, and were included in the analyses. Criteria for the primary end point were met in 68.5% of 206 women in UF-1 and in 76.5% of 189 women in UF-2 who received elagolix plus add-back therapy, as compared with 8.7% of 102 women and 10% of 94 women, respectively, who received placebo (P<0.001 for both trials). Among the women who received elagolix alone, the primary end point was met in 84.1% of 104 women in UF-1 and in 77% of 95 women in UF-2. Hot flushes (in both trials) and metrorrhagia (in UF-1) occurred significantly more commonly with elagolix plus add-back therapy than with placebo. Hypoestrogenic effects of elagolix, especially decreases in bone mineral density, were attenuated with add-back therapy. CONCLUSIONS: Elagolix with add-back therapy was effective in reducing heavy menstrual bleeding in women with uterine fibroids.

Predictors of response for elagolix with add-back therapy in women with heavy menstrual bleeding associated with uterine fibroids.

BACKGROUND: Uterine fibroids are one of the most common neoplasms found among women globally, with a prevalence of approximately 11 million women in the United States alone. The morbidity of this common disease is significant because it is the leading cause of hysterectomy and causes significant functional impairment for women of reproductive age. Factors including age, body mass index, race, ethnicity, menstrual blood loss, fibroid location, and uterine and fibroid volume influence the incidence of fibroids and severity of symptoms. Elagolix is an oral gonadotropin-releasing hormone receptor antagonist that competitively inhibits pituitary gonadotropin-releasing hormone receptor activity and suppresses the release of gonadotropins from the pituitary gland, resulting in dose-dependent suppression of ovarian sex hormones, follicular growth, and ovulation. In Elaris Uterine Fibroids 1 and Uterine Fibroids 2, 2 replicate multicenter, double-blind, randomized, placebo-controlled, phase 3 studies, treatment of premenopausal women with elagolix with hormonal add-back therapy demonstrated reduction in heavy menstrual bleeding associated with uterine fibroids. OBJECTIVE: This analysis aimed to evaluate the safety and efficacy of elagolix (300 mg twice a day) with add-back therapy (1 mg estradiol/0.5 mg norethindrone acetate once a day) in reducing heavy menstrual bleeding associated with uterine fibroids in various subgroups of women over 6 months of treatment. STUDY DESIGN: Data were pooled from Elaris Uterine Fibroid-1 and Uterine Fibroid-2 studies, which evaluated premenopausal women (18-51 years) with heavy menstrual bleeding (>80 mL menstrual blood loss per cycle, alkaline hematin methodology) and ultrasound-confirmed uterine fibroid diagnosis. Subgroups analyzed included age, body mass index, race, ethnicity, baseline menstrual blood loss, fibroid location, and uterine and primary fibroid volume (largest fibroid identified by ultrasound). The primary endpoint was the proportion of women with <80 mL menstrual blood loss during the final month and ≥50% menstrual blood loss reduction from baseline to final month. Secondary and other efficacy endpoints included mean change in menstrual blood loss from baseline to final month, amenorrhea, symptom severity, and health-related quality of life. Adverse events and other safety endpoints were monitored. RESULTS: The overall pooled Elaris Uterine Fibroid-1 and Uterine Fibroid-2 population was typical of women with fibroids, with a mean age of 42.4 (standard deviation, 5.4) years and a mean body mass index of 33.6 (standard deviation, 7.3) kg/m2 and 67.6% of participants being black or African American women. A wide range of baseline uterine and fibroid volumes and menstrual blood loss were also represented in the overall pooled study population. In all subgroups, the proportion of responders to the primary endpoint, mean change in menstrual blood loss, amenorrhea, reduction in symptom severity, and improvement in health-related quality of life were clinically meaningfully greater for women who received elagolix with add-back therapy than those who received placebo and consistent with the overall pooled study population for the primary endpoint (72.2% vs 9.3%), mean change in menstrual blood loss (-172.5 mL vs -0.8 mL), amenorrhea (50.4% vs 4.5%), symptom severity (-37.1 vs -9.2), and health-related quality of life score (39.9 vs 8.9). Adverse events by subgroup were consistent with the overall pooled study population. CONCLUSION: Elagolix with hormonal add-back therapy was effective in reducing heavy menstrual bleeding associated with uterine fibroids independent of age, body mass index, race, ethnicity, baseline menstrual blood loss, fibroid location, and uterine and primary fibroid volume.

Letrozole versus clomiphene for infertility in the polycystic ovary syndrome.

BACKGROUND: Clomiphene is the current first-line infertility treatment in women with the polycystic ovary syndrome, but aromatase inhibitors, including letrozole, might result in better pregnancy outcomes. METHODS: In this double-blind, multicenter trial, we randomly assigned 750 women, in a 1:1 ratio, to receive letrozole or clomiphene for up to five treatment cycles, with visits to determine ovulation and pregnancy, followed by tracking of pregnancies. The polycystic ovary syndrome was defined according to modified Rotterdam criteria (anovulation with either hyperandrogenism or polycystic ovaries). Participants were 18 to 40 years of age, had at least one patent fallopian tube and a normal uterine cavity, and had a male partner with a sperm concentration of at least 14 million per milliliter; the women and their partners agreed to have regular intercourse with the intent of conception during the study. The primary outcome was live birth during the treatment period. RESULTS: Women who received letrozole had more cumulative live births than those who received clomiphene (103 of 374 [27.5%] vs. 72 of 376 [19.1%], P=0.007; rate ratio for live birth, 1.44; 95% confidence interval, 1.10 to 1.87) without significant differences in overall congenital anomalies, though there were four major congenital anomalies in the letrozole group versus one in the clomiphene group (P=0.65). The cumulative ovulation rate was higher with letrozole than with clomiphene (834 of 1352 treatment cycles [61.7%] vs. 688 of 1425 treatment cycles [48.3%], P<0.001). There were no significant between-group differences in pregnancy loss (49 of 154 pregnancies in the letrozole group [31.8%] and 30 of 103 pregnancies in the clomiphene group [29.1%]) or twin pregnancy (3.4% and 7.4%, respectively). Clomiphene was associated with a higher incidence of hot flushes, and letrozole was associated with higher incidences of fatigue and dizziness. Rates of other adverse events were similar in the two treatment groups. CONCLUSIONS: As compared with clomiphene, letrozole was associated with higher live-birth and ovulation rates among infertile women with the polycystic ovary syndrome.

Sexual function in infertile women with polycystic ovary syndrome and unexplained infertility.

BACKGROUND: While female sexual dysfunction is a frequent occurrence, characteristics in infertile women are not well delineated. Furthermore, the impact of infertility etiology on the characteristics in women with differing androgen levels observed in women with polycystic ovary syndrome and unexplained infertility has not been assessed. OBJECTIVE: The objective of the study was to determine the characteristics of sexual dysfunction in women with polycystic ovary syndrome and unexplained infertility. STUDY DESIGN: A secondary data analysis was performed on 2 of Eunice Kennedy Shriver National Institute of Child Health and Human Development Cooperative Reproductive Medicine Networks clinical trials: Pregnancy in Polycystic Ovary Syndrome Study II and Assessment of Multiple Intrauterine Gestations From Ovarian Stimulation. Both protocols assessed female sexual function using the Female Sexual Function Inventory and the Female Sexual Distress Scale. RESULTS: Women with polycystic ovary syndrome had higher weight and body mass index than women with unexplained infertility (each P < .001), greater phenotypic (Ferriman-Gallwey hirsutism score, sebum score, and acne score; each P < .001), and hormonal (testosterone, free testosterone, and dehydroepiandrosterone; each P < .001) evidence of androgen excess. Sexual function scores, as assessed by the Female Sexual Function Inventory, were nearly identical. The Female Sexual Distress Scale total score was higher in women with polycystic ovary syndrome. The mean Female Sexual Function Inventory total score increased slightly as the free androgen index increased, mainly as a result of the desire subscore. This association was more pronounced in the women with unexplained infertility. CONCLUSION: Reproductive-age women with infertility associated with polycystic ovary syndrome and unexplained infertility, despite phenotypic and biochemical differences in androgenic manifestations, do not manifest clinically significant differences in sexual function.

Fertility-related quality of life from two RCT cohorts with infertility: unexplained infertility and polycystic ovary syndrome.

STUDY QUESTION: Does fertility-related quality of life (FertiQOL) differ by infertility diagnosis between women with polycystic ovary syndrome (PCOS) and their partners, compared with couples with unexplained infertility (UI)? SUMMARY ANSWER: Women with PCOS report lower QOL than those with UI, whereas males with UI report lower QOL than males with PCOS partners. WHAT IS KNOWN ALREADY: The fertility-specific QOL survey, FertiQOL, has been used to examine fertility-related QOL in a number of worldwide cohorts. Few data have addressed fertility-related QOL as a function of infertility diagnosis. Overall, men report better QOL than women with infertility, and there is variation in FertiQOL scores across different samples from different countries. STUDY DESIGN, SIZE, DURATION: This was a prospective, cohort study derived from two concurrent, randomized clinical trials, and designed to examine QOL in infertile females with PCOS and UI at the time of enrollment compared with each other and their male partners; to compare concordance FertiQOL scores in this study across other worldwide cohorts; and to determine if baseline FertiQOL was associated with pregnancy outcome. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with PCOS and their partners (n = 733 and n = 641, respectively), and couples with UI (n = 865 women and 849 men) completed a validated fertility-specific QOL survey (FertiQOL) at the time of the study screening visit. PCOS women were randomized to either clomiphene citrate or letrozole treatment; couples with UI were randomized to clomiphene citrate, letrozole or gonadotrophin plus IUI. FertiQOL results were compiled by diagnosis (PCOS or UI) and compared by diagnosis and sex using Wilcoxon Rank-Sum testing. Relationships between baseline FertiQOL and pregnancy outcomes were examined using logistic regression. Multivariable models were performed to assess the association between FertiQOL scores and key participant characteristics. MAIN RESULTS AND THE ROLE OF CHANCE: Women with PCOS had lower total FertiQOL scores (72.3 ± 14.8) than those with UI (77.1 ± 12.8; P < 0.001); this was true for each domain (except Relational). These differences were largely explained by variation in BMI, hirsutism, household income and age. Women had lower overall FertiQOL scores than their male partners. Males with PCOS partners had higher scores than males with UI (84.9 ± 10.2 versus 83.3 ± 10.8; P = 0.003). Scores were not consistently associated with conception or pregnancy outcome. LIMITATIONS, REASONS FOR CAUTION: The use of multiple tests of association may have resulted in spurious statistically significant findings. Inherent sociodemographic differences between women with PCOS and those with UI largely account for the lower QOL in women with PCOS. Our study was unable to assess if changes in QOL affected pregnancy outcome as FertiQOL data were collected prior to treatment. Finally, the participants for both studies represent their local communities, but are not a population-based sample and thus firm conclusions about how representative these couples are to the general population must be made with caution. WIDER IMPLICATIONS OF THE FINDINGS: Women with PCOS with elevated BMI and hirsutism scores and with lower socioeconomic status may require more, targeted psychosocial support than those with other diagnoses. Possible attribution of infertility to the male partner appears to result in a lower QOL. There appears to be substantial national variation in FertiQOL scores, with US-based cohorts reporting overall higher QOL.

Smoking in infertile women with polycystic ovary syndrome: baseline validation of self-report and effects on phenotype.

STUDY QUESTION: Do women with polycystic ovary syndrome (PCOS) seeking fertility treatment report smoking accurately and does participation in infertility treatment alter smoking? SUMMARY ANSWER: Self-report of smoking in infertile women with PCOS is accurate (based on serum cotinine levels) and smoking is unlikely to change over time with infertility treatment. WHAT IS KNOWN ALREADY: Women with PCOS have high rates of smoking and it is associated with worse insulin resistance and metabolic dysfunction. STUDY DESIGN, SIZE, DURATION: Secondary study of smoking history from a large randomized controlled trial of infertility treatments in women with PCOS (N = 626) including a nested case-control study (N = 148) of serum cotinine levels within this cohort to validate self-report of smoking. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with PCOS, age 18-40, seeking fertility who participated in a multi-center clinical trial testing first-line ovulation induction agents conducted at academic health centers in the USA. MAIN RESULTS AND THE ROLE OF CHANCE: Overall, self-report of smoking in the nested case-control study agreed well with smoking status as determined by measure of serum cotinine levels, at 90% or better for each of the groups at baseline (98% of never smokers had cotinine levels <15 ng/ml compared with 90% of past smokers and 6% of current smokers). There were minor changes in smoking status as determined by serum cotinine levels over time, with the greatest change found in the smoking groups (past or current smokers). In the larger cohort, hirsutism scores at baseline were lower in the never smokers compared with past smokers. Total testosterone levels at baseline were also lower in the never smokers compared with current smokers. At end of study follow-up insulin levels and homeostatic index of insulin resistance increased in the current smokers (P < 0.01 for both) compared with baseline and with non-smokers. The chance for ovulation was not associated with smoking status, but live birth rates were increased (non-significantly) in never or past smokers. LIMITATIONS, REASONS FOR CAUTION: The limitations include the selection bias involved in our nested case-control study, the possibility of misclassifying exposure to second hand smoke as smoking and our failure to capture self-reported changes in smoking status after enrollment in the trial. WIDER IMPLICATIONS OF THE FINDINGS: Because self-report of smoking is accurate, further testing of smoking status is not necessary in women with PCOS. Because smoking status is unlikely to change during infertility treatment, extra attention should be focused on smoking cessation in current or recent smokers who seek or who are receiving infertility treatment.

Phase 2, double-blind, randomized, placebo-controlled study of the safety and efficacy of elagolix in women with polycystic ovary syndrome.

Objective: Evaluate the efficacy and safety of elagolix, a GnRH antagonist, to treat polycystic ovarian syndrome (PCOS). Design: A phase 2, multicenter, double-blind, randomized, placebo-controlled trial. Setting: Outpatient and academic medical centers. Patients: One hundred fourteen women with PCOS (aged 18-35 years, body mass index 18.5-38 kg/m2). Interventions: Patients were randomized 2:2:2:2:2:3 to elagolix (25 mg twice daily, 50 mg once daily, 75 mg twice daily, 150 mg once daily, and 300 mg twice daily) or placebo. Main Outcome Measures: The primary endpoint was menstrual cycle normalization (defined as 2 menstrual cycles 21-35 days in length during the 4-month treatment period). The secondary endpoint was change from baseline to week 1 in the area under the luteinizing hormone (LH) serum concentration-time curve (AUC). Additional endpoints included change from baseline in serum hormone levels. Results: No significant improvement in restoring normal menstrual cycles was observed in treated subjects; 3 of 114 patients met the primary endpoint. Six patients experienced progesterone elevations indicative of ovulation. The LH levels decreased from baseline to week 16, and LH AUC was significantly reduced from baseline to week 1 in all elagolix treatment groups (P<.1 vs placebo). Follicle-stimulating hormone (FSH) levels generally remained stable through week 16, with no significant differences in FSH AUCs. Serum estradiol and testosterone concentrations were consistently reduced from baseline in all elagolix dose groups compared with placebo. Adverse event rates were similar across treatment groups. Conclusions: Elagolix treatment did not normalize the ovulatory cycle in patients with PCOS. Clinical Trial Registration Number: NCT03951077.

High throughput, cell type-specific analysis of key proteins in human endometrial biopsies of women from fertile and infertile couples.

BACKGROUND: Although histological dating of endometrial biopsies provides little help for prediction or diagnosis of infertility, analysis of individual endometrial proteins, proteomic profiling and transcriptome analysis have suggested several biomarkers with altered expression arising from intrinsic abnormalities, inadequate stimulation by or in response to gonadal steroids or altered function due to systemic disorders. The objective of this study was to delineate the developmental dynamics of potentially important proteins in the secretory phase of the menstrual cycle, utilizing a collection of endometrial biopsies from women of fertile (n = 89) and infertile (n = 89) couples. METHODS AND RESULTS: Progesterone receptor-B (PGR-B), leukemia inhibitory factor, glycodelin/progestagen-associated endometrial protein (PAEP), homeobox A10, heparin-binding EGF-like growth factor, calcitonin and chemokine ligand 14 (CXCL14) were measured using a high-throughput, quantitative immunohistochemical method. Significant cyclic and tissue-specific regulation was documented for each protein, as well as their dysregulation in women of infertile couples. Infertile patients demonstrated a delay early in the secretory phase in the decline of PGR-B (P < 0.05) and premature mid-secretory increases in PAEP (P < 0.05) and CXCL14 (P < 0.05), suggesting that the implantation interval could be closing early. Correlation analysis identified potential interactions among certain proteins that were disrupted by infertility. CONCLUSIONS: This approach overcomes the limitations of a small sample number. Protein expression and localization provided important insights into the potential roles of these proteins in normal and pathological development of the endometrium that is not attainable from transcriptome analysis, establishing a basis for biomarker, diagnostic and targeted drug development for women with infertility.

Legal considerations in reproductive medicine.

Legal issues affect reproductive medical practice throughout the entire world. The breadth and depth of this interrelationship extend far beyond the scope of one series of articles in Views and Reviews. Given this limitation, we have chosen to present five topics, all different, but illustrative of key concepts that influence our practice of reproductive medicine. Our hope is that this "medical-legal sampler" will both inform and provoke thoughtful consideration of the ways we can best and most responsibly practice and serve our patients.

Bone Mineral Density Changes Associated With Pregnancy, Lactation, and Medical Treatments in Premenopausal Women and Effects Later in Life.

Bone mineral density (BMD) changes during the life span, increasing rapidly during adolescence, plateauing in the third decade of life, and subsequently entering a phase of age-related decline. In women, menopause leads to accelerated bone loss and an increase in fracture risk. Between peak bone mass attainment and menopause, BMD is generally stable and the risk of fracture is typically low. This time period is marked by life events such as pregnancy and lactation, which transiently decrease BMD, yet their long-term effects on fracture risk are less certain. BMD may also be altered by exposure to medications that affect bone metabolism (e.g., contraceptives, glucocorticoids, antidiabetic medications, antiepileptic drugs). Although oral contraceptives are often believed to be neutral with regard to bone health, depot medroxyprogesterone acetate (DMPA) and gonadotropin-releasing hormone (GnRH) agonists have been associated with decreases in BMD. Development of newer medical therapies, principally GnRH antagonists (e.g., ASP1707, elagolix, linzagolix, relugolix), for treatment of endometriosis-associated pelvic pain and heavy menstrual bleeding due to uterine fibroids has renewed interest in the short- and long-term impacts of changes in BMD experienced by premenopausal women. It is important to understand how these drugs influence BMD and put the findings into context with regard to measurement variability and naturally occurring factors that influence bone health. This review summarizes what is known about the effects on bone health pregnancy, lactation, and use of DMPA, GnRH agonists, and GnRH antagonists in premenopausal women and potential consequences later in life.

Clomiphene, metformin, or both for infertility in the polycystic ovary syndrome.

BACKGROUND: The polycystic ovary syndrome is a common cause of infertility. Clomiphene and insulin sensitizers are used alone and in combination to induce ovulation, but it is unknown whether one approach is superior. METHODS: We randomly assigned 626 infertile women with the polycystic ovary syndrome to receive clomiphene citrate plus placebo, extended-release metformin plus placebo, or a combination of metformin and clomiphene for up to 6 months. Medication was discontinued when pregnancy was confirmed, and subjects were followed until delivery. RESULTS: The live-birth rate was 22.5% (47 of 209 subjects) in the clomiphene group, 7.2% (15 of 208) in the metformin group, and 26.8% (56 of 209) in the combination-therapy group (P<0.001 for metformin vs. both clomiphene and combination therapy; P=0.31 for clomiphene vs. combination therapy). Among pregnancies, the rate of multiple pregnancy was 6.0% in the clomiphene group, 0% in the metformin group, and 3.1% in the combination-therapy group. The rates of first-trimester pregnancy loss did not differ significantly among the groups. However, the conception rate among subjects who ovulated was significantly lower in the metformin group (21.7%) than in either the clomiphene group (39.5%, P=0.002) or the combination-therapy group (46.0%, P<0.001). With the exception of pregnancy complications, adverse-event rates were similar in all groups, though gastrointestinal side effects were more frequent, and vasomotor and ovulatory symptoms less frequent, in the metformin group than in the clomiphene group. CONCLUSIONS: Clomiphene is superior to metformin in achieving live birth in infertile women with the polycystic ovary syndrome, although multiple birth is a complication. (ClinicalTrials.gov number, NCT00068861 [ClinicalTrials.gov].).

Decision trees for identifying predictors of treatment effectiveness in clinical trials and its application to ovulation in a study of women with polycystic ovary syndrome.

BACKGROUND: Double-blind, randomized clinical trials are the preferred approach to demonstrating the effectiveness of one treatment against another. The comparison is, however, made on the average group effects. While patients and clinicians have always struggled to understand why patients respond differently to the same treatment, and while much hope has been held for the nascent field of predictive biomarkers (e.g. genetic markers), there is still much utility in exploring whether it is possible to estimate treatment efficacy based on demographic and baseline variables. METHODS: The pregnancy in polycystic ovary syndrome (PPCOS) study was a prospective, multi-center, randomized clinical trial comparing three ovulation induction regimens: clomiphene citrate (CC), metformin and the combination of the two. There were 446 women who ovulated in response to the treatments among the entire 626 participants. In this report, we focus on the 418 women who received CC (alone or combined with metformin) to determine if readily available baseline physical characteristics and/or easily obtainable baseline measures could be used to distinguish treatment effectiveness in stimulating ovulation. We used a recursive partitioning technique and developed a node-splitting rule to build decision tree models that reflected within-node and within-treatment responses. RESULTS: Overall, the combination of CC plus metformin resulted in an increased incidence of ovulation compared with CC alone. This is particularly so in women with relatively larger left ovarian volumes (≥ 19.5 cubic cm), and a left ovarian volume <19.5 cubic cm was related to treatment outcomes for all subsequent nodes. Women who were older, who had higher baseline insulin, higher waist-to-hip circumference ratio or higher sex hormone-binding globulin levels had better ovulatory rates with CC alone than with the combination of CC plus metformin. CONCLUSIONS: Polycystic ovary syndrome (PCOS) is a phenotypically diverse condition. Both baseline laboratory and clinical parameters can predict the ovulatory response in women with PCOS undergoing ovulation induction. Without a priori hypotheses with regard to any predictors, the observation regarding left ovary volume is novel and worthy of further investigation and validation.

Diagnosis and clinical delineation of mosaic tetrasomy 5p.

OBJECTIVE: Our objective was to review the phenotypic and genetic characteristics of tetrasomy 5p from the fetal period until adulthood including prenatal diagnostic evaluations. BACKGROUND: Tetrasomy 5p is a rare chromosomal abnormality. Of the 14 reports, most document mosaic tetrasomy 5p resulting from a supernumerary marker chromosome or isochromosome. There is a wide range of phenotypic manifestations with severity related to more proximal breakpoints and the degree of mosaicism. DESIGN: We conducted a systematic review using Scopus, PubMed Central® and Ovid MEDLINE® from inception through July 1, 2018 for all articles describing tetrasomy 5p. All articles describing the syndrome of tetrasomy 5p were included. RESULTS: Of the 15 included cases, 13 exhibited mosaic tetrasomy and two had complete tetrasomy identified by amniocentesis. The most common features include seizures (8/11 live births, 73%), hypotonia (7/11 live births, 64%), developmental delay (7/9 cases that reached childhood, 78%), abnormal external ears (6/11 live births, 55%), short stature (6/11 live births, 55%), ventriculomegaly (5/11 live births, 45.5%) and congenital heart defect (6/15 cases, 40%). The clinical phenotype ranged in severity from mild with no defining characteristics to severe with seizures, developmental delay, and multiple congenital anomalies, resulting in early death. Of these 15 cases, only 6 were diagnosed prenatally by prenatal genetic testing (40%) with prenatal ultrasound identifying abnormalities in 4/6 (67%). Confined placental mosaicism (CPM) was diagnosed in six additional cases due to discordance between CVS and amniocentesis results. Four of the five live births returned for evaluation and each showed normal development. CONCLUSIONS: Fourteen out of 15 (93%) cases of tetrasomy 5p were associated with an abnormal phenotype. Once a diagnosis is made prenatally, a detailed anatomy ultrasound and fetal echocardiogram must be performed to further characterize any structural abnormalities of the fetus and potentially estimate the clinical severity. Caution should be exercised when prenatal diagnosis of mosaic tetrasomy 5p is found by chorionic villus sampling. CVS alone is insufficient to diagnose tetrasomy 5p and needs to be confirmed with amniocentesis. Our review seeks to inform clinicians on the current literature regarding tetrasomy 5p so that they may better counsel patients when this syndrome is diagnosed.

Elagolix Treatment for Up to 12 Months in Women With Heavy Menstrual Bleeding and Uterine Leiomyomas.

OBJECTIVE: To investigate the safety and efficacy of elagolix, an oral gonadotropin-releasing hormone antagonist, with hormonal add-back therapy for up to 12 months in women with heavy menstrual bleeding associated with uterine leiomyomas. METHODS: Elaris UF-EXTEND was a phase 3 extension study that evaluated an additional 6 months (up to 12 months total) of elagolix 300 mg twice daily with hormonal add-back therapy (estradiol 1 mg and norethindrone acetate 0.5 mg once daily) in women who completed an initial 6 months of the same treatment in one of two preceding phase 3 studies. The primary endpoint was the percentage of women with both less than 80 mL menstrual blood loss during final month and a 50% or greater reduction in menstrual blood loss from baseline to final month. Safety evaluations included adverse events and bone mineral density changes. The planned sample size of UF-EXTEND was based on estimated rollover and discontinuation rates in the two preceding studies. RESULTS: From September 2016 to March 2019, 433 women were enrolled in UF-EXTEND. Of these women, 218 received up to 12 months of elagolix with add-back therapy; the mean±SD age of this group was 42.4±5.4 years and 67.3% were black. The percentage of women who met the primary endpoint in this elagolix with add-back group was 87.9% (95% CI [83.4-92.3]). The most frequently reported adverse events with up to 12 months of elagolix plus add-back therapy were hot flush (6.9%), night sweats (3.2%), headache (5.5%), and nausea (4.1%). Mean percent decreases in bone mineral density from baseline to extension month 6 were significantly less with elagolix plus add-back therapy than with elagolix alone {between-group difference in lumbar spine: -3.3 (95% CI [-4.1 to -2.5])}. CONCLUSION: Up to 12 months of elagolix with add-back therapy provided sustained reduction in menstrual blood loss in women with uterine leiomyomas, with the addition of add-back therapy attenuating the hypoestrogenic effects of elagolix alone. No new or unexpected safety concerns were associated with an additional 6 months of elagolix with addback therapy. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT02925494.

Pregnancy registry: three-year follow-up of children conceived from letrozole, clomiphene, or gonadotropins.

OBJECTIVE: To study the development of children conceived from non-IVF infertility treatments consisting of gonadotropins, clomiphene, or letrozole. DESIGN: Prospective cohort study. SETTING: U.S. academic health centers. PATIENT(S): Children of women with polycystic ovary syndrome who conceived with letrozole (LTZ) or clomiphene (CC) in the PPCOS II study or women with unexplained infertility (AMIGOS study) who conceived with LTZ, CC, or gonadotropin (GN). INTERVENTION(S): Longitudinal annual follow-up from birth to age 3. MAIN OUTCOME MEASURE(S): Scores from Ages and Stages Developmental Questionnaire (ASQ), MacArthur-Bates Communicative Development Inventory (MCDI), and annual growth. RESULT(S): One hundred eighty-five children from 160 families participated in at least one follow-up evaluation from the two infertility trials. Most multiple gestations in the follow-up study resulted from GN treatment (n = 14) followed by CC (n = 6) and LTZ (n = 3). There were no significant differences among the three groups at any time point with respect to abnormal scores on the ASQ. On the MCDI Words and Gestures, the LTZ group scored significantly higher than the GN group for most items (phrases, early gestures, later gestures, and total gestures). Children in the CC group scored significantly higher than the GN group for the later gestures and total gestures items. CONCLUSION(S): Differences in growth and cognitive developmental rates among children conceived with first-line infertility therapies, including LTZ, are relatively minor and likely due to differences in multiple pregnancy rates.

Introduction: An update on bone metabolism and osteoporosis.

Osteoporosis continues to be a major public health challenge in both women and men. There are more than 2 million low-impact fractures in the United States every year, 39% of which occur in men. The mortality rate in the first year after hip fracture is estimated at 20% to 25% in women and is even higher in men. The goal of this Views and Reviews is to provide an update regarding bone metabolism and contemporary approaches to prevention and treatment of osteoporosis.

Extended-release metformin does not reduce the clomiphene citrate dose required to induce ovulation in polycystic ovary syndrome.

CONTEXT: When used for ovulation induction, higher doses of clomiphene may lead to antiestrogenic side effects that reduce fecundity. It has been suggested that metformin in combination with clomiphene can restore ovulation to some clomiphene-resistant anovulators with polycystic ovary syndrome (PCOS). OBJECTIVE: Our objective was to determine if cotreatment with extended-release metformin (metformin XR) can lower the threshold dose of clomiphene needed to induce ovulation in women with PCOS. DESIGN: A secondary analysis of data from the National Institute of Child Health and Human Development Cooperative Multicenter Reproductive Medicine Network prospective, double-blind, placebo-controlled multicenter clinical trial, Pregnancy in Polycystic Ovary Syndrome, was performed. SETTING: Study volunteers at multiple academic medical centers were included. PARTICIPANTS: Women with PCOS and elevated serum testosterone who were randomized to clomiphene alone or with metformin (n = 209 in each group) were included in the study. INTERVENTIONS: Clomiphene citrate, 50 mg daily for 5 d, was increased to 100 and 150 mg in subsequent cycles if ovulation was not achieved; half also received metformin XR, 1000 mg twice daily. Treatment was for up to 30 wk or six cycles, or until first pregnancy. MAIN OUTCOME MEASURES: Ovulation was confirmed by a serum progesterone more than or equal to 5 ng/ml, drawn prospectively every 1-2 wk. RESULTS: The overall prevalence of at least one ovulation after clomiphene was 75 and 83% (P = 0.04) for the clomiphene-only and clomiphene plus metformin groups, respectively. Using available data from 314 ovulators, the frequency distribution of the lowest clomiphene dose (50, 100, or 150 mg daily) resulting in ovulation was indistinguishable between the two treatment groups. CONCLUSION: Metformin XR does not reduce the lowest dose of clomiphene that induces ovulation in women with PCOS.

Ovulatory response to treatment of polycystic ovary syndrome is associated with a polymorphism in the STK11 gene.

CONTEXT: Clomiphene and insulin sensitizers such as metformin are used to induce ovulation in polycystic ovary syndrome (PCOS), but the ovulatory response is variable, and the causes of this variation are poorly understood. OBJECTIVE: Our objective was to identify predictive genetic polymorphisms and other determinants of ovulatory response. DESIGN: This was a substudy of a multicenter randomized clinical trial. SETTING: This study was performed at academic medical centers and their affiliates. PARTICIPANTS: A total of 312 women with PCOS were included in the study. MAIN OUTCOME MEASURES: Historical, biometric, biochemical, and genetic parameters were performed. RESULTS: We found that the C allele of a single nucleotide polymorphism in the STK11 gene (expressed in liver; also known as LKB1) was associated with a significantly decreased chance of ovulation in PCOS women treated with metformin. In an analysis of ovulation per cycle, the adjusted odds ratio (OR) comparing the C/C genotype to the G/G genotype was 0.30 [95% confidence interval (CI) 0.14, 0.66], and the OR for the C/G genotype vs. the G/G genotype was also 0.30 (95% CI 0.14, 0.66). In an analysis of metformin-treated subjects, we found that the percentage of women who ovulated increased with the number of G alleles present: 48% (10 of 21) of C/C women, 67% (32 of 48) of C/G women, and 79% (15 of 19) of G/G women ovulated. We also found that increased frequency of ovulation was associated with lower body mass index (BMI) [adjusted OR of 2.36 (95% CI 1.65, 3.36) and 2.05 (95% CI 1.46, 2.88), respectively, for comparisons of BMI less than 30 vs. BMI equal to or more than 35, BMI 30-34 vs. BMI equal to or more than 35, in the analysis of ovulation per cycle], a lower free androgen index (FAI) [adjusted OR of 1.59 (95% CI 1.17, 2.18) for FAI<10 vs. FAI>or=10], and a shorter duration of attempting conception [adjusted OR of 1.63 (95% CI 1.20, 2.21) for<1.5 vs.>or=1.5 yr]. CONCLUSIONS: We have demonstrated that a polymorphism in STK11, a kinase gene expressed in liver and implicated in metformin action, is associated with ovulatory response to treatment with metformin alone in a prospective randomized trial. The interaction with the effects of changes in modifiable factors (e.g. BMI or FAI) requires further study.

Breath alcohol level and plasma amino acids: a comparison between older and younger chronic alcohol-dependent patients.

AIM: The aim of the present study is to examine the distribution of plasma excitatory and inhibitory amino acids, according to the age and current breath alcohol levels (BrAl+/-), of alcohol-dependent patients. PARTICIPANTS AND METHODS: 78 alcohol-dependent patients (mean age=46.2+/-11 years, men/women=54/24) were clinically tested, including the determination of the major excitatory as well as inhibitory amino acids. The independent variables were gender, age and current alcohol consumption measured with the breath alcohol level (BrAl+/-status). RESULTS: In comparison to BrAl negatives, BrAl positives had higher plasma levels of glutamic acid (P=0.01) and proline (P=0.026), and lower levels of aminobutyric acid (P=0.002), serine (P=0.031) and urea (P=0.01). In the BrAl positives, no age effect was found related to the plasma amino acids. In contrast, the BrAl negatives displayed age-related differences. The older (>or=50 years) BrAl negative patients had higher plasma levels of cystine, tyrosine, citrulline and urea, and lower histidine levels, compared to the younger group (<50 years). In general, differences in plasma levels of certain amino acids were dependent on gender, BrAl status, age and biochemical markers (GGT, MCV) of alcohol abuse. CONCLUSIONS: Abstaining patients (BrAl-/) display age-related differences in AAs' distribution, while active drinking (BrAl+/) seems to even out those differences, underpinning the hypothesis that drinking mimics changes seen with advanced age.
