Long acting progestogens versus combined oral contraceptive pill for preventing recurrence of endometriosis related pain: the PRE-EMPT pragmatic, parallel group, open label, randomised controlled trial.

OBJECTIVES: To evaluate the clinical effectiveness of long acting progestogens compared with the combined oral contraceptive pill in preventing recurrence of endometriosis related pain. DESIGN: The PRE-EMPT (preventing recurrence of endometriosis) pragmatic, parallel group, open label, randomised controlled trial. SETTING: 34 UK hospitals. PARTICIPANTS: 405 women of reproductive age undergoing conservative surgery for endometriosis. INTERVENTIONS: Participants were randomised in a 1:1 ratio using a secure internet facility to a long acting progestogen (depot medroxyprogesterone acetate or levonorgestrel releasing intrauterine system) or the combined oral contraceptive pill. MAIN OUTCOME MEASURES: The primary outcome was pain measured three years after randomisation using the pain domain of the Endometriosis Health Profile 30 (EHP-30) questionnaire. Secondary outcomes (evaluated at six months, one, two, and three years) included the four core and six modular domains of the EHP-30, and treatment failure (further therapeutic surgery or second line medical treatment). RESULTS: 405 women were randomised to receive a long acting progestogen (n=205) or combined oral contraceptive pill (n=200). At three years, there was no difference in pain scores between the groups (adjusted mean difference -0.8, 95% confidence interval -5.7 to 4.2, P=0.76), which had improved by around 40% in both groups compared with preoperative values (an average of 24 and 23 points for long acting progestogen and combined oral contraceptive pill groups, respectively). Most of the other domains of the EHP-30 also showed improvement at all time points compared with preoperative scores, without evidence of any differences between groups. Women randomised to a long acting progestogen underwent fewer surgical procedures or second line treatments compared with those randomised to the combined oral contraceptive pill group (73 v 97; hazard ratio 0.67, 95% confidence interval 0.44 to 1.00). CONCLUSIONS: Postoperative prescription of a long acting progestogen or the combined oral contraceptive pill results in similar levels of improvement in endometriosis related pain at three years, with both groups showing around a 40% improvement compared with preoperative levels. While women can be reassured that both options are effective, the reduced risk of repeat surgery for endometriosis and hysterectomy might make long acting reversible progestogens preferable for some.

Effects of the selective AMPA modulator NBI-1065845 on the pharmacokinetics of midazolam or ethinyl estradiol-levonorgestrel in healthy adults.

This parallel-arm, phase I study investigated the potential cytochrome P450 (CYP)3A induction effect of NBI-1065845 (TAK-653), an investigational α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor potentiator in phase II development for major depressive disorder. The midazolam treatment arm received the sensitive CYP3A substrate midazolam on Day 1, followed by NBI-1065845 alone on Days 5-13; on Day 14, NBI-1065845 was administered with midazolam, then NBI-1065845 alone on Day 15. The oral contraceptive treatment arm received ethinyl estradiol-levonorgestrel on Day 1, then NBI-1065845 alone on Days 5-13; on Day 14, NBI-1065845 was administered with ethinyl estradiol-levonorgestrel, then NBI-1065845 alone on Days 15-17. Blood samples were collected for pharmacokinetic analyses. The midazolam treatment arm comprised 14 men and 4 women, of whom 16 completed the study. Sixteen of the 17 healthy women completed the oral contraceptive treatment arm. After multiple daily doses of NBI-1065845, the geometric mean ratios (GMRs) (90% confidence interval) for maximum observed concentration were: midazolam, 0.94 (0.79-1.13); ethinyl estradiol, 1.00 (0.87-1.15); and levonorgestrel, 0.99 (0.87-1.13). For area under the plasma concentration-time curve (AUC) from time 0 to infinity, the GMRs were as follows: midazolam, 0.88 (0.78-0.98); and ethinyl estradiol, 1.01 (0.88-1.15). For levonorgestrel, the GMR for AUC from time 0 to the last quantifiable concentration was 0.87 (0.78-0.96). These findings indicate that NBI-1065845 is not a CYP3A inducer and support its administration with CYP3A substrates. NBI-1065845 was generally well tolerated, with no new safety signals observed after coadministration of midazolam, ethinyl estradiol, or levonorgestrel.

High-dose oral contraceptives induce hyperinsulinemia without altering immune activation in diet-induced obesity which persists even following a dietary low-fat diet intervention.

Combined oral contraceptives (COCs) are known to cause weight gain and alter metabolic and immunological pathways. However, modifications in arterial or venous thrombotic risk profiles of women of reproductive ages on COC remain unclear. The study aimed at assessing the impact of COC on immune activation in diet-induced obesity. We further established whether the dietary intervention of switching from a high-fat diet (HFD) to a low-fat diet (LFD) attenuates immunological responses. Twenty (n=20) five-week-old female Sprague Dawley rats were randomly divided into two diet groups of HFD (n=15) and LFD (n=5) and were monitored for eight weeks. After eight weeks, animals in the HFD group switched diets to LFD and were randomly assigned to receive high-dose COC (HCOC) or low-dose COC (LCOC) for six weeks. Animals on HFD significantly gained weight and had a higher lee index when compared to the LFD group (p < 0.05). Moreover, the triglyceride-glucose index, insulin, and other metabolic parameters also increased in the HFD group compared to the LFD group (p < 0.001). Consistently, the levels of interleukin (IL)-6 and tumor necrosis factor-alpha (TNF-α), were elevated in the HFD group when compared to the LFD group (p < 0.05). Upon switching from a high-fat to a low-fat diet, insulin levels persistently increased in animals receiving HCOC treatment compared to the LFD and HFD/LFD groups (p < 0.05). Thus, in a rat model of HFD-feeding, short-term HCOC treatment induces long-term metabolic dysregulation, which persists despite dietary intervention. However, further studies are recommended to confirm these findings.

Should Combined Hormonal Contraception Be Stopped in the Perioperative Period?

Should Combined Hormonal Contraception Be Stopped in the Perioperative Period?A 34-year-old woman is scheduled to undergo surgery to manage a torn anterior cruciate ligament in her left knee. Her only medication is an estrogen- and progestin-containing oral contraceptive pill (OCP). Should she stop her combined oral contraception to reduce the risk of a postoperative blood clot?

Effects of Lemborexant on the Pharmacokinetics of Oral Contraceptives: Results From a Phase 1 Drug-Drug Interaction Study in Healthy Females.

Lemborexant is a dual orexin receptor antagonist approved in multiple countries including the United States, Canada, and Japan for the treatment of insomnia in adults. As women of childbearing potential may be prescribed insomnia drugs, a drug-drug interaction study was conducted. This single-center, open-label, fixed-sequence study examined potential drug-drug interactions between lemborexant and an oral contraceptive (OC) in healthy females (18-44 years, n = 20). The purpose of this study was to determine the effect of lemborexant 10 mg (at steady state) on the pharmacokinetics of a single dose of OC (0.03 mg ethinyl estradiol and 1.5 mg norethindrone acetate), assess the effect of a single dose of OC on lemborexant pharmacokinetics, and evaluate safety and tolerability of lemborexant and OC coadministration. Ethinyl estradiol maximum plasma drug concentration was not altered by lemborexant coadministration; area under the curve from zero time to the last quantifiable concentration was slightly increased, by 13%. No clinically relevant effects on norethindrone acetate pharmacokinetics were observed. Coadministration of OC with lemborexant had no clinically relevant effect on the steady-state pharmacokinetics of lemborexant. Adverse events were consistent with the known safety profile. These results support the conclusion that lemborexant and OC can be coadministered without dose adjustment.

Adding Combined Oral Contraceptives or Metformin to Laser Treatment in Polycystic Ovarian Syndrome Hirsute Patients.

BACKGROUND: Hirsutism is estimated to affect 10% to 20% of females, provoking significant psychological damage and social embarrassment. Polycystic ovary syndrome is a major cause of hirsutism. AIM: Assessing the impact of adding combined oral contraceptives (COCs) or metformin to laser hair removal on the quality of life of polycystic ovarian syndrome (PCOS) patients with hirsutism. METHODOLOGY: One-hundred-fifty PCO patients diagnosed with hirsutism were included in this study. Patients were randomized into three groups: group 1 received laser hair removal alone, group 2 received metformin and laser hair removal, and group 3 received COCs and laser hair removal. A diode laser with a wavelength of 810 nm was used for hair removal in all patients according to a protocol of 6 monthly sessions followed by another two sessions after three and six months. Patients were assessed using a visual analog scale (VAS) and Dermatology Life Quality Index (DLQI) and a customized questionnaire (Hirsutism Life Quality Index; HLQI). RESULTS: All patients showed a significant improvement in both quality indices (DLQI and HLQI) after treatment relative to pretreatment. Group 3 showed significantly better improvements when compared with group 2 and group 1. At three and six months, group 3 showed non-significantly better DLQI and HLQI as compared with at zero months. On the other hand, group 2 patients displayed significant worsening of both DLQI and HLQI scores at three months, with subsequent improvements again at six. Finally, group 1 patients showed nonsignificant worsening at three months, and significant worsening at 6 months. CONCLUSION: Combining hormonal treatment with laser hair removal can achieve greater hair reduction, significant improvements in patients' QOL, and better maintenance as compared with when combining metformin with laser hair removal or conducting alone.

Comparison of dienogest versus combined oral contraceptive pills in the treatment of women with adenomyosis: A randomized clinical trial.

OBJECTIVE: To compare the efficacy and safety of dienogest with combined oral contraceptives (COCs) for treating adenomyosis-associated symptoms. METHODS: This was a randomized clinical trial including women with symptomatic adenomyosis conducted from March 1, 2019 to August 1, 2020 at Assiut Woman's Health Hospital, Egypt. Participants were randomly assigned to the dienogest group or COCs group. The primary outcome was the level of adenomyosis-associated pain from before to 6 months after treatment measured by a visual analog scale (VAS). Changes in the uterine bleeding pattern, uterine volume, and uterine artery blood flow were also reported. RESULTS: The VAS score of pain was significantly decreased in both groups; however, the decreased rate was more pronounced in the dienogest group (3.21 ± 1.18) in comparison with the COCs group (4.92 ± 1.22). Bleeding pattern was improved greatly; uterine volume and uterine artery blood flow decreased significantly in the dienogest group. However, women in the dienogest group reported a higher rate of side effects. CONCLUSION: Dienogest and COCs are effective in treating adenomyosis-associated symptoms after 6 months of use but dienogest is more effective. The decrease in uterine volume and uterine artery blood flow may be the cause of the treatment effect. Dienogest carries a higher risk of side effects. CLINICAL TRIAL: gov: NCT03890042.

Options for Prevention and Management of Menstrual Bleeding in Adolescent Patients Undergoing Cancer Treatment: ACOG Committee Opinion, Number 817.

ABSTRACT: Obstetrician-gynecologists frequently are consulted either before the initiation of cancer treatment to request menstrual suppression or during an episode of severe heavy bleeding to stop bleeding emergently. Adolescents presenting emergently with severe uterine bleeding usually require only medical management; surgical management rarely is required. Surgical management should be considered for patients who are not clinically stable, or for those whose conditions are not suitable for medical management or have failed to respond appropriately to medical management. When used continuously, combined hormonal contraceptives are effective for producing amenorrhea, although complete amenorrhea cannot be guaranteed. The risk of venous thromboembolism in patients with cancer is compounded by multiple factors, including presence of metastatic or fast-growing, biologically aggressive cancers; hematologic cancers; treatment-related factors such as surgery or central venous catheters; and the number and type of comorbid conditions. Although as a group, patients undergoing cancer treatment are at elevated risk of venous thromboembolism compared with the general population, this risk may be extremely elevated for certain patients and existing guidance on risk stratification should be consulted. The decision to use estrogen in patients with cancer should be tailored to the individual patient after collaborative consideration of the risk-benefit ratio with the patient and the health care team; the patient should be closely monitored for known adverse effects such as liver toxicity and venous thromboembolism.

Tolosa-Hunt syndrome relapse during pregnancy following chronic intake of combined oral contraceptives.

Tolosa-Hunt syndrome (THS) is a rare syndrome of painful ophthalmoplegia secondary to an idiopathic granulomatous inflammation affecting the cavernous sinus, superior orbital fissure or orbit. Pregnancy and pregnancy-related hormones have been identified as potential triggers. A 39-year-old gravida-2 para-1 woman with prior chronic intake of combined oral contraceptives (COC) suffered two episodes of painful ophthalmoplegia-the first event with spontaneous remission and the relapse occurring during pregnancy and with complete resolution following steroid treatment. MRI revealed a postinflammatory mass at the junction of the left orbital apex and anterior cavernous sinus, supporting the diagnosis of THS. To our knowledge, this is the first report of a THS relapse occurring during pregnancy following a chronic history of COC intake. This case adds to the growing evidence supporting the relationship between immune and hormonal factors that may be present during pregnancy and the disease pathogenesis of THS.

A safety evaluation of current medications for adult women with the polycystic ovarian syndrome not pursuing pregnancy.

INTRODUCTION: The polycystic ovary syndrome (PCOS) is a very prevalent disorder in premenopausal women. Cardiovascular risk factors cluster in these patients, raising concern about the safety of the drugs commonly used to ameliorate symptoms of androgen excess in in this population at risk of cardiovascular morbidity. AREAS COVERED: This review summarizes the clinical efficacy and safety profiles of drugs commonly used for the management of hyperandrogenic symptoms and endometrial protection in adult women with PCOS who do not seek pregnancy. EXPERT OPINION: Antiandrogenic drugs usually used in adult women with PCOS carry a low risk of severe side effects. In spite of the cardiovascular risk profile of women with PCOS, and that individualized risk assessment is of paramount importance, there is no solid evidence supporting that the use of combined oral contraceptives in these women increases the risk of cardiovascular or thromboembolic events compared with the general population. However, virtually all these drugs are used in an off-label fashion. Large, high-quality studies addressing the long-term safety of pharmacological treatments in women with PCOS are definitely needed.

Evaluation of the effect of a new oral contraceptive containing estetrol and drospirenone on hemostasis parameters.

OBJECTIVE: To assess the effect on hemostasis parameters of a new combined oral contraceptive (COC). STUDY DESIGN: In this randomized, single centre, open-label, exploratory study, healthy women received either 15 mg estetrol/3 mg drospirenone (E4/DRSP) (n = 39), 30 mcg ethinylestradiol/150 mcg levonorgestrel (EE/LNG) (n = 30), or 20 mcg ethinylestradiol/3 mg drospirenone (EE/DRSP) (n = 32) for six 28-day cycles. Blood was collected at baseline, cycle 3, and cycle 6. Median change from baseline was evaluated for procoagulant, anticoagulant, and fibrinolytic parameters, and for sex hormone-binding globulin (SHBG). RESULTS: Median change of endogenous thrombin potential (ETP) based activated protein C sensitivity resistance (APCr) at cycle 6 was +30% for E4/DRSP, +165% for EE/LNG (p-value <0.05 vs E4/DRSP), and +219% for EE/DRSP (p-value <0.05 vs E4/DRSP). Changes to prothrombin fragment 1 + 2 and SHBG for E4/DRSP, EE/LNG, and EE/DRSP were +23%, +71%, and +64% (p-value <0.05 vs E4/DRSP); and +55%, +74% and +251% (p-value <0.05 vs E4/DRSP), respectively. At cycle 6, changes to other hemostasis parameters for E4/DRSP were similar or smaller than for EE/LNG or EE/DRSP. CONCLUSIONS: In this study, changes in hemostasis parameters after treatment with 6 cycles of E4/DRSP were smaller or similar to those observed for EE/LNG. Similar, but more pronounced changes were also observed versus EE/DRSP, which supports the hypothesis that the effect of COCs on hemostasis parameters is mainly mediated by the estrogenic component. Further studies are needed to provide more insight into the venous thromboembolic risk of E4/DRSP. IMPLICATIONS STATEMENT: This study reports that the effects on hemostasis parameters of a COC containing 15 mg E4/3 mg DRSP are less or similar to those for EE/LNG or EE/DRSP. It also demonstrates that the choice of estrogen modulates the effects of COCs on hemostasis parameters.

Functional reorganization of brain networks across the human menstrual cycle.

The brain is an endocrine organ, sensitive to the rhythmic changes in sex hormone production that occurs in most mammalian species. In rodents and nonhuman primates, estrogen and progesterone's impact on the brain is evident across a range of spatiotemporal scales. Yet, the influence of sex hormones on the functional architecture of the human brain is largely unknown. In this dense-sampling, deep phenotyping study, we examine the extent to which endogenous fluctuations in sex hormones alter intrinsic brain networks at rest in a woman who underwent brain imaging and venipuncture for 30 consecutive days. Standardized regression analyses illustrate estrogen and progesterone's widespread associations with functional connectivity. Time-lagged analyses examined the temporal directionality of these relationships and suggest that cortical network dynamics (particularly in the Default Mode and Dorsal Attention Networks, whose hubs are densely populated with estrogen receptors) are preceded-and perhaps driven-by hormonal fluctuations. A similar pattern of associations was observed in a follow-up study one year later. Together, these results reveal the rhythmic nature in which brain networks reorganize across the human menstrual cycle. Neuroimaging studies that densely sample the individual connectome have begun to transform our understanding of the brain's functional organization. As these results indicate, taking endocrine factors into account is critical for fully understanding the intrinsic dynamics of the human brain.

Persistent organic pollutants, pre-pregnancy use of combined oral contraceptives, age, and time-to-pregnancy in the SELMA cohort.

BACKGROUND: We are exposed to several chemicals such as persistent organic pollutants (POPs) in our everyday lives. Prior evidence has suggested that POPs may have adverse effects on reproductive function by disrupting hormone synthesis and metabolism. While there is age-related decline of fertility, the use of hormonal combined oral contraceptives (COCs) and its association to return of fertility remains controversial. The goal of this study is to investigate the association between exposure to POPs, both individually and as a mixture, and fecundability measured as time-to-pregnancy (TTP) according to pre-pregnancy use of COCs and age. METHODS: Using the SELMA (Swedish Environmental Longitudinal Mother and Child, Allergy and Asthma) study, we have identified 818 pregnant women aged 18-43 years (mean 29 years) with data on how long they tried to get pregnant and what was their most recently used contraceptive method. These data were collected at enrollment to the study (median week 10 of pregnancy). Concentrations of 22 POPs and cotinine were analyzed in the blood samples collected at the same time as the questions on TTP and pre-pregnancy use of contraceptive. Analyses were done on the association between POPs exposure and TTP measured as continuous (months) and binary (infertile for those with TTP > 12 months). To study the chemicals individually, Cox regression and logistic regression were used to estimate fecundability ratios (FRs) and odds ratios (ORs), respectively. Weighted quantile sum (WQS) regression was used to investigate the chemicals as a mixture where chemicals of concern were identified above the 7.6% threshold of equal weights. To perform the subgroup analysis, we stratified the sample according to use of COCs as the most recent pre-pregnancy contraception method and age (< 29 years, and ≥ 29 years). The models were adjusted for parity, regularity of menses, maternal body mass index (BMI) and smoking status, and stratified as described above. RESULTS: Prior to stratification, none of the POPs were associated with fecundability while increased exposure to HCB, PCB 74 and 118 had higher odds of infertility. Upon stratification, POP exposure was significantly associated with longer TTP in women aged ≥29 years who did not use COC. Specifically, PCBs 156, 180, 183, and 187 were associated with reduced fecundability while PCBs 99, 153, 156, 180, 183, and 187 had higher odds of infertility. As a mixture, we identified the chemicals of concern for a longer TTP include PCBs 118, 156, 183, and 187. Moreover, chemicals of concern identified with increased odds of infertility were PCB 74, 156, 183, 187, and transnonachlor. CONCLUSION: Serum concentrations of selected POPs, both as individual chemicals and as a mixture, were significantly associated with lower fecundability and increased odds of infertility in women aged 29 years and above not using COC as their most recent pre-pregnancy contraceptive. Our findings suggest that pre-pregnancy use of oral contraceptive and age may modify the link between POPs and fecundability. The differences of specific chemicals in the individual analysis and as a mixture support the need to study combination effects of chemicals when evaluating reproductive outcomes.

Serum Metabolome Changes in Relation to Prothrombotic State Induced by Combined Oral Contraceptives with Drospirenone and Ethinylestradiol.

The association between hypercoagulability and use of drospirenone (DRSP) and ethinylestradiol (EE) containing combined oral contraceptives (COCs) is an important clinical concern. We have previously reported that the two formulations of DRSP combined with EE (namely, DRSP/20EE and DRSP/30EE) bring about a prothrombotic state in hemostatic traits of female users. We report here the serum metabolomic changes in the same study cohort in relation to the attendant prothrombotic state induced by COC use, thus offering new insights on the underlying biochemical mechanisms contributing to the altered coagulatory profile with COC use. A total of 78 healthy women participated in this study and were grouped as follows: control group not using oral contraceptives (n = 25), DRSP/20EE group (n = 27), and DRSP/30EE group (n = 26). Untargeted metabolomics revealed changes in amino acid concentrations, particularly a decrease in glycine and an increase in both cysteine and lanthionine in the serum, accompanied by variations in oxidative stress markers in the COC users compared with the controls. Of importance, this study is the first to link specific amino acid variations, serum metabolites, and the oxidative metabolic profile with DRSP/EE use. These molecular changes could be linked to specific biophysical coagulatory alterations observed in the same individuals. These new findings lend evidence on the metabolomic substrates of the prothrombotic state associated with COC use in women and informs future personalized/precision medicine research. Moreover, we underscore the importance of an interdisciplinary approach to evaluate venous thrombotic risk associated with COC use.

The effectiveness of quick starting oral contraception containing nomegestrol acetate and 17-ß estradiol on ovulation inhibition: A randomized controlled trial.

To determine the effectiveness of quick starting combined oral contraception (COC) contain 2.5 mg nomegestrol acetate and 1.5 mg estradiol (NOMAC/E2) comparing with 0.075 mg gestodene and 0.02 mg ethinyl estradiol (GS/EE) on ovarian ovulation inhibition rate, we conducted a non-inferiority randomized controlled trial involving 69 healthy female volunteers aged 18-40 years who had normal menstrual history and were randomized at a 2:1 ratio to take one pack of COC containing either NOMAC/E2 (study group) or GS/EE (control group) starting on menstrual cycle Day7-9. The ovarian activity was assessed by using Hoogland and Skouby grading. Forty-six and 23 participants were randomized to NOMAC/E2 and GS/EE groups, respectively. Baseline characteristics were similar between groups. No significant difference was observed between the study and control groups for ovulation inhibition rate (93.4% vs. 95.6%, risk difference: -2.2%, 95% CI: -13.1, 8.8), ovarian quiescence rate (91.2% vs. 91.2%, P = 1.000), persistent cyst rate (2.2% vs. 4.4%, P = 1.000), and ovulation rate (6.6% vs. 4.4%, P = 1.000). Quick starting COC during day7-9 of menstrual cycle can inhibit ovulation for more than 90%. The quick starting NOMAC/E2 is non-inferior to GS/EE for preventing ovulation and suppressing follicular growth.

Estradiol Valerate in COC Has More Favorable Inflammatory Profile Than Synthetic Ethinyl Estradiol: A Randomized Trial.

CONTEXT: Combined oral contraceptives (COCs) alter inflammatory status and lipid metabolism. Whether different estrogens have different effects is poorly understood. OBJECTIVE: We compared the effects of COCs containing ethinyl estradiol (EE) or estradiol valerate (EV) and dienogest (DNG) with those containing DNG only on inflammation and lipid metabolism. DESIGN: Randomized, controlled, open-label clinical trial. SETTING: Two-center study in Helsinki and Oulu University Hospitals. PARTICIPANTS: Fifty-nine healthy, young, nonsmoking women with regular menstrual cycles. Age, body mass index, and waist-to-hip ratio were comparable in all study groups at the beginning. Fifty-six women completed the study (EV + DNG, n = 20; EE + DNG, n = 19; DNG only, n = 17). INTERVENTIONS: Nine-week continuous use of COCs containing either EV + DNG or EE + DNG, or DNG only as control. MAIN OUTCOME MEASURES: Parameters of chronic inflammation (high-sensitivity C-reactive protein [hs-CRP], and pentraxin 3 [PTX-3]) and lipid profile (high-density lipoprotein [HDL], low-density lipoprotein [LDL], triglycerides, and total cholesterol). RESULTS: Serum hs-CRP increased after 9-week use of EE + DNG (mean change ± standard deviation 1.10 ± 2.11 mg/L) compared with EV + DNG (-0.06 ± 0.97 mg/L, P = 0.001) or DNG only (0.13 ± 0.68 mg/L, P = 0.021). Also, PTX-3 increased in the EE + DNG group compared with EV + DNG and DNG-only groups (P = 0.017 and P = 0.003, respectively). In the EE + DNG group, HDL and triglycerides increased compared with other groups (HDL: EE + DNG 0.20 ± 0.24 mmol/L vs EV + DNG 0.02 ± 0.20 mmol/L [P = 0.002] vs DNG 0.02 ± 0.18 mmol/L [P = 0.002]; triglycerides: EE + DNG 0.45 ± 0.21 mmol/L vs EV + DNG 0.18 ± 0.36 mmol/L [P = 0.003] vs DNG 0.06 ± 0.18 mmol/L [P < 0.001]). CONCLUSIONS: EV + DNG and DNG only had a neutral effect on inflammation and lipids, while EE + DNG increased both hs-CRP and PTX-3 levels as well as triglycerides and HDL.

Atogepant Has No Clinically Relevant Effects on the Pharmacokinetics of an Ethinyl Estradiol/Levonorgestrel Oral Contraceptive in Healthy Female Participants.

The incidence of migraine is higher among women than men and peaks during the reproductive years, when contraceptive medication use is common. Atogepant, a potent, selective antagonist of the calcitonin gene-related peptide receptor-in development for migraine prevention-is thus likely to be used by women taking oral contraceptives. This phase 1, open-label, single-center, 2-period, fixed-sequence study examined the effect of multiple-dose atogepant 60 mg once daily on the single-dose pharmacokinetics of a combination oral contraceptive, ethinyl estradiol 0.03 mg and levonorgestrel 0.15 mg (EE/LNG), in healthy postmenopausal or oophorectomized women. For participants in period 1, a single dose of EE/LNG was followed by a 7-day washout. In period 2, atogepant was given once daily on days 1-17; an oral dose of EE/LNG was coadministered with atogepant on day 14. Plasma pharmacokinetic parameters for EE and LNG were assessed following administration with and without atogepant. Twenty-six participants aged 45-64 years enrolled; 22 completed the study in accordance with the protocol. The area under the concentration-time curve extrapolated to infinity (AUC0-∞ ) of LNG was increased by 19% when administered with atogepant. Coadministration of atogepant and a single dose of EE/LNG did not substantially alter the pharmacokinetics of EE; the ∼19% increase in plasma AUC0-∞ of LNG is not anticipated to be clinically significant. Overall, atogepant alone and in combination with EE/LNG was generally well tolerated, with no new safety signals identified.

Evaluation of different antiandrogenic progestins on clinical and biochemical variables in polycystic ovary syndrome.

Objectives: The aim of the study was to update the results of a previous study published 10 years ago and compare the effect on hyperandrogenism of a newer progestin, dienogest (DNG), in a combined oral contraceptive (COC) formulation with ethinylestradiol (EE), with that of COCs containing the same dose of EE in combination with drospirenone (DRSP) and chlormadinone acetate (CMA).Methods: Sixty women with polycystic ovary syndrome (PCOS) aged between 16 and 35 and requiring antiandrogenic contraceptive treatment were randomised to one of three treatment groups: EE 30 µg/DRSP 3 mg, EE 30 µg/CMA 2 mg, EE 30 µg/DNG 2 mg. We evaluated the effects of the three COCs on sex hormone-binding globulin (SHBG) and biochemical markers of hyperandrogenism.Results: After 3 months of treatment, serum androgen concentrations were significantly improved in all treatment groups. Serum concentrations of SHBG were significantly increased with all COC treatments (p < 0.0001). Interestingly, DRSP had a greater effect (+218%; p < 0.0001) on serum SHBG concentrations compared with DNG and CMA (p < 0.04 and p < 0.002, respectively). Serum concentrations of total testosterone significantly decreased in all groups (p < 0.0001). DRSP had a significantly greater effect on total testosterone concentrations compared with DNG (p = 0.002) and CMA (p < 0.0001).Conclusion: Our study showed that DNG exerted an important stimulatory effect on SHBG concentrations, which was less than that of DRSP but greater than that of CMA. Similar results were also obtained for dehydroepiandrosterone sulphate and total testosterone.

Pooled analysis of bleeding profile, efficacy and safety of oral oestradiol valerate/dienogest in women aged 25 and under.

Purpose: To evaluate differences in key outcomes between younger and older women receiving the oral contraceptive oestradiol valerate/dienogest (E2V/DNG).Methods: We conducted a pooled post hoc analysis of primary data from 12 studies of E2V/DNG, stratified by age (≤25 [n = 1309] and >25 [n = 2132] years). Outcomes included safety, efficacy, bleeding profile and hormone-withdrawal-associated symptoms (HWAS). Bleeding and HWAS analyses are also presented for women aged ≤20 years (n = 362). Discontinuations were considered a proxy for patient satisfaction.Results: Results were generally similar for younger and older women. The percentage of women aged ≤25 and >25 years experiencing intracyclic bleeding did not differ between groups (13.4% and 12.8% at cycle 12, respectively), with similar results in women aged ≤20 years (12.7%, cycle 12). Rates of withdrawal bleeding were very similar in women aged ≤25 and >25 years (78.5% and 78.9%, respectively, cycle 12). We also found a similar adjusted Pearl index in the two age groups (0.45 vs 0.57, respectively), similar rates of AEs and HWAS and no difference in discontinuations.Conclusions: Women aged ≤25 and >25 years have a similar experience with an E2V/DNV oral contraceptive, supporting this as an appropriate contraceptive option in younger and older women.

Pharmacodynamics of combined estrogen-progestin oral contraceptives: 4. Effects on uterine and cervical epithelia.

Introduction: Steroid hormones are responsible for specific changes in the endometrium during the menstrual cycle, when they are sequentially secreted and, because of this, in the early days sequential combined oral contraceptive regimens were utilized. The same basic concept has been utilized with multi-phasic regimens, in order to produce endometrial pictures mimicking the normal cycle.Areas covered: The Endometrial effects of progestins and estrogens; combined monophasic high- (50 µg), medium- (30 µg), low- (20 µg), ultralow- (15 µg) estrogen content; sequential regimens; multiphasic combinations; treatment schedules.Cervical effects of combined high-dose and sequential combinations, including evidence for an increase in malignant lesions.Expert opinion: Overall, combined oral contraceptives (COCs) inhibit normal proliferative changes and the endometrium becomes thin, narrow, with widely spaced glands and pre-decidual changes in the stroma. During the first few cycles the progestin induces a coexistence of proliferative and secretory features; with time, the picture changes because the progestin induces a down-regulation of estrogen receptors, resulting in tortuous glands similar to those in the secretory phase, but characterized by a quiescent, atrophic glandular epithelium.In the cervical epithelium, under the influence of high-dose COCs, endocervical glands became hypersecretory and in some instances, distinctive type of atypical polypoid endocervical hyperplasia is found.
