The drospirenone only pill as a contraceptive option for breastfeeding women: First data on users' acceptability and newborn development.

BACKGROUND: Progestin-only pills (POPs) have been used for contraception in breastfeeding women for years. The existing guidelines allow the use of these contraceptives. METHODS: Multicenter study with a single visit and retrospective data review. The study involved 100 women who used a drospirenone-only pill (DRSP) for contraception for at least 5 months during breastfeeding. The study aimed to analyze for those successful users the impact on new-born development, the bleeding profile and evaluate user satisfaction. RESULTS: Analysis of the newborns showed that their growth parameters length and weight, were within the expected range of standard development. The mean birth weight was 3368 g, with the lowest recorded weight being 2860 g and the highest 5040 g. The median length of the newborns was 55 cm, ranging from 35 to 65 cm. All new-borns demonstrated appropriate growth within the established percentiles. Acceptability with the bleeding profile was rated with a VAS score: the mean acceptability rating was 82.8. Women aged 35 years or older reported significantly higher acceptability compared to younger women (≥35 years: mean = 88.4, SD = 16.5; <35 years: mean = 80.3, SD = 20.2) (p = 0.02). Sixty-one patients (N = 61; 61.0%; 95% CI: 50.7 - 70.4%) expressed willingness to continue using DRSP after breastfeeding. CONCLUSION: Among those patients who continued the use of the DRSP only-pill for 5 months, this study shows no negative impact for new-borns, with no clinical influence observed on their growth. Additionally, those users expressed high satisfaction with the bleeding profile of the pill.Clinical trial registration number: DRKS00028438 .

A randomised double-blind trial to determine the bleeding profile of the prolonged-release contraceptive dienogest 2 mg/ethinylestradiol 0.02 mg versus an immediate-release formulation of drospirenone 3 mg/ethinylestradiol 0.02 mg.

BACKGROUND: Dienogest (DNG) 2 mg/ethinylestradiol (EE) 0.02 mg is the first low-dose combined oral contraceptive (COC) with a prolonged-release formulation that allows stable plasma concentrations and has high contraceptive efficacy (Pearl index: 0.2). The aim of this trial was to determine the bleeding profile of this contraceptive compared to an immediate release formulation. METHODS: This prospective double-blind randomised controlled trial evaluated the bleeding patterns of DNG 2 mg/EE 0.02 mg compared with immediate-release drospirenone (DRSP) 3 mg/EE 0.02 mg in a 24/4-day regimen over nine cycles (randomisation ratio, 5:2). Participants recorded scheduled and unscheduled bleeding/spotting data using an electronic diary. A non-inferiority analysis for the proportion of participants with unscheduled bleeding/spotting was prespecified for Cycles 2-6. Safety, including adverse events, were monitored throughout the trial. RESULTS: Seven-hundred six and 288 participants received DNG/EE and DRSP/EE, respectively. Scheduled bleeding patterns per each 28-day cycle were similar in both groups. During Cycles 2-6, the proportion of participants with unscheduled bleeding/spotting was significantly lower in the DNG/EE group (50.5% [280/574] than in the DRSP/EE group (72.8% [171/235]]; treatment difference 22.3% [95% CI 15.9, 28.6%]; p < 0.0001). A low proportion of participants discontinued the trial due to bleeding disorders (1.7% and 0.7%, respectively). The safety profiles were similar for both treatments. CONCLUSIONS: The prolonged-release DNG 2 mg/EE 0.02 mg offers a significant decrease in unscheduled bleeding/spotting compared with an immediate-release COC, DRSP/EE, combined with high contraceptive efficacy and a very low adverse event profile.

The prolonged-release DNG 2 mg/EE 0.02 mg offers a significant decrease in unscheduled bleeding compared with an immediate-release COC while maintaining contraceptive efficacy and with no new safety signals.

The drospirenone (DRSP)-only pill: clinical implications in the daily use.

OBJECTIVES: Progestins used in contraception are either components of combined hormonal contraceptives or are used as a single active ingredient. Progestins are highly effective in long-term contraception and have a very good safety profile with very few contraindications. METHODS: An oestrogen-free ovulation inhibitor POP has been authorised in the USA and the EU. It contains 4 mg of drospirenone (DRSP). The hormone administration regimen of 24 days followed by a 4-day hormone-free period was chosen to improve bleeding control and to maintain oestradiol concentrations at early follicular- phase levels, preventing oestrogen deficiency. RESULTS: Clinical trials have demonstrated high contraceptive effectiveness, a very low risk of cardiovascular risk events and a favourable bleeding pattern. Due to the long half-life of DRSP (30-34 h), the effectiveness is maintained even in case of a forgotten pill on a single occasion. Studies involving deliberate 4 days in one cycle 24-hour delays in taking a pill have demonstrated that ovulation inhibition is maintained if a single pill is missed. CONCLUSIONS: This review article will describe the clinical impact in the daily use of the 4 mg DRSP only pill and the resulting data on the effectiveness and safety of this hormonal contraceptive.

The 4 mg drospirenone-only pill improves the bleeding profile in comparison to 0.075 mg desogestrel and achieves high contraceptive efficacy even with a 24 h missed pill window.

Miconazole for the treatment of vulvovaginal candidiasis. In vitro, in vivo and clinical results. Review of the literature.

At concentrations achieved following systemic administration, the primary effect of imidazoles and triazoles on fungi is inhibition of 14-α-sterol demethylase, a microsomal cytochrome P450 (CYP) enzyme. Imidazoles and triazoles impair the biosynthesis of ergosterol for the cytoplasmic membrane and lead to the accumulation of 14-α-methyl sterols. The synthetic imidazole miconazole is additionally able to increase intracellular reactive oxygen species, at least in part through inhibition of fungal catalase and peroxidase. This unique feature of miconazole is probably the basis for its fungicidal activity in C. albicans, in addition to the fungistatic mode of action. Studies show that miconazole is superior to nystatin treatment and demonstrate its impact as one of the best options in managing vulvovaginal candidiasis. Regarding recurrent vulvovaginal candidiasis, several new drugs are currently developed to ensure effective treatment also for this group of patients.

The progestin-only pills drospirenone 4 mg and desogestrel 0.075 mg as an option for the management of dysmenorrhea and mastodynia.

INTRODUCTION: Dysmenorrhea and mastodynia are the most common gynecologic pain causes in women of all ages and races during their reproductive life. The following study aimed to show the influence of two POP´s in the development of dysmenorrhea and mastodynia after nine months of use. MATERIAL AND METHODS: A total of 858 women with 6691 drospirenone (DRSP) cycles and 332 women with 2487 desogestrel (DSG) cycles were analyzed. Women included in this study were all child-bearing potentials, at risk of pregnancy, agreeing to use only the study medication for contraception for the duration of the study medication treatment, aged 18 to 45. RESULTS: At screening, 168 (19.6%) of the 858 patients using DRSP and 64 (19,3%) of the DSG patients reported that they had suffered from dysmenorrhea within six cycles prior to the first visit before starting with the medication. 20,2% of the DRSP and 10,9% of the DSG group had a sever dysmenorrhea. After 9 cycles this was reduced to 0,6% and 3,1% respectively. In total, 96 women (11.2%) in the DRSP and 49 (14,8%) experienced mastodynia within six cycles before the screening. Of these 91.6% in the DRSP group and 91,8% in the DSG group had no or mild mastodynoa at follow-up. DISCUSSION: The progestins 4 mg and desogestrel 0,075 mg showed a marked effect in the non-contraceptive aspects of dysmenorrhea and mastodynia so that new possibilities are opened for these two benign gynecological diseases. Future studies must reaffirm these first data.

Bleeding profile of women with cardiovascular risk factors using a drospirenone only pill with 4 mg over nine cycles compared to desogestrel 0.075 mg.

OBJECTIVE: Progestin-only pills are associated with irregular bleeding patterns, including amenorrhea. Desogestrel (DSG) 75 mcg, a pill that inhibits ovulation, shows poor cycle control that may harm acceptability and compliance. A Drospirenone (DRSP)-only pill was developed with 24 & 4 days of active & placebo days every 28-day cycle to improve cycle control. STUDY DESIGN: A phase III study in healthy women aged 18 to 45 years was performed to compare the bleeding profile of women taking a DRSP versus DSG over nine cycles. 249 women were older > 35 years: 173 using DRSP and 73 DSG. 259 women had a BMI > 25 kg/m2: 189 using DRSP and 70 DSG and 340 women were smokers: 237 using DRSP and 103 DSG. The amount of unscheduled bleeding/spotting days was analyzed in each of these sub-groups and compared statistically. RESULTS: Age: During cycles 2-4, the mean number of unscheduled bleeding days and spotting was 8.1 (SD10.53) for DRSP and 20.1 (19.41) for DSG; p = .0089. BMI > 25 kg/m2: During cycles 2-4 the mean number of unscheduled bleeding days and spotting was 7.8 (SD 12.18) for DRSP and 17.7 for DSG (SD 19.39); p = .0001. Smokers: During cycles 2-4, the mean number of unscheduled bleeding days and spotting was 9.6 (SD 11.69) for DRSP and 17.4 for DSG (SD 17.47); p = .0016. CONCLUSIONS: These analyses show the improvement in the bleeding profile of women with specific cardiovascular risk factors using the DRSP only oral contraceptive product compared to DSG.ImplicationsAn improvement in the bleeding profile of women with specific cardiovascular risk factors like age > 35 years, BMI > 25kg/m2, and smokers using the DRSP only oral contraceptive product is described.Herby a higher contraceptive efficacy in these patients that additionally benefit from estrogen-free contraceptive methods is expected.

Overall and bleeding-related discontinuation rates of a new oral contraceptive containing 4 mg drospirenone only in a 24/4 regimen and comparison to 0.075 mg desogestrel.

OBJECTIVES: Progestin-only pills do not increase the risk of venous thromboembolism, stroke, and myocardial infarction but are associated with poor cycle control. A novel estrogen-free pill containing only drospirenone (DRSP) to improve bleeding patterns and tolerability and reduce discontinuation rates has been introduced into the market. The present study aims to describe the improvement in the acceptability of this DRSP-only pill, e.g. regarding the bleeding profile and the reduction in discontinuation rates due to unacceptable bleeding compared to desogestrel (DSG). STUDY DESIGN: Double-blind, double-dummy prospective phase III study in healthy women aged 18-45 years evaluating a total of 858 women with 6691 DRSP and 332 women with 2487 DSG treatment cycles. RESULTS: Overall, 82 (9.6%) women in the DRSP group and 44 (13.3%) women in the DSG group experienced treatment-emergent adverse events (TEAEs) leading to premature termination of the trial meaning that 32% more women in the DRSP group finished the trial in comparison to the DSG group (based on the AUC of Kaplan-Meier's curves). Discontinuation rates due to abnormal bleeding were 3.7% for DRSP and 7.3% for DSG users. This is a 55.7% lower discontinuation rate in the DRSP group compared to the DSG group. CONCLUSIONS: This report describes the improvement in acceptability and bleeding profile of women using the new DRSP-only oral contraceptive compared to DSG, providing a better quality of life and adherence to the contraceptive method as demonstrated by lower discontinuation rates of women using the estrogen-free DRSP-only pill.

Efficacy and cardiovascular safety of the new estrogen-free contraceptive pill containing 4 mg drospirenone alone in a 24/4 regime.

BACKGROUND: A new estrogen-free contraceptive has been approved by both the FDA and more than 15 European authorities. It is composed of drospirenone (DRSP) at a dosage of 4 mg in a regimen 24/4. The molecule is known to have anti-gonadotropic, anti-mineralocorticoid, anti-estrogenic, and antiandrogenic properties. The purpose of these clinical trials with a new estrogen-free contraceptive was to introduce a contraceptive method with high efficacy and showing a profile with low cardiovascular risks. METHODS: Three European and American multicenter clinical trials have been conducted in more than 2500 patients and more than 25,000 cycles, not only demonstrating an excellent efficacy (Pearl Index of 0.73) but also investigating possible cardiovascular risks. In the USA study, 422 participants (41.9%) had a risk factor for VTE, while in the European studies, 261 patients (16.6%) had at least one VTE risk factor. Amount of arterial and venous thromboembolic events, hemostasiological data, blood pressure development, and ECG data were evaluated. RESULTS: No single case of VTE was documented, no changes in hemastosiological parameters were observed, a small decrease in RR in patients with pretreatment values between 130 and 140 and/or 85 to 90 mm HG and no influence on ECG parameters were observed. CONCLUSIONS: The introduction of a new estrogen-free contraceptive with 4 mg of non-micronized drospirenone in a 24/4-day regimen expands contraception options for women as not only a high efficacy could be demonstrated during clinical trials but also a very high cardiovascular safety profile was observed even in women with cardiovascular risk factors.

Chronic Inflammation in PCOS: The Potential Benefits of Specialized Pro-Resolving Lipid Mediators (SPMs) in the Improvement of the Resolutive Response.

PCOS as the most common endocrine disorder of women in their reproductive age affects between 5-15 % of the female population. Apart from its cardinal symptoms, like irregular and anovulatory cycles, hyperandrogenemia and a typical ultrasound feature of the ovary, obesity, and insulin resistance are often associated with the disease. Furthermore, PCOS represents a status of chronic inflammation with permanently elevated levels of inflammatory markers including IL-6 and IL-18, TNF-α, and CRP. Inflammation, as discovered only recently, consists of two processes occurring concomitantly: active initiation, involving "classical" mediators including prostaglandins and leukotrienes, and active resolution processes based on the action of so-called specialized pro-resolving mediators (SPMs). These novel lipid mediator molecules derive from the essential ω3-poly-unsaturated fatty acids (PUFAs) DHA and EPA and are synthesized via specific intermediates. The role and benefits of SPMs in chronic inflammatory diseases like obesity, atherosclerosis, and Diabetes mellitus has become a subject of intense research during the last years and since PCOS features several of these pathologies, this review aims at summarizing potential roles of SPMs in this disease and their putative use as novel therapeutics.

Oestrogen-free oral contraception with a 4 mg drospirenone-only pill: new data and a review of the literature.

Purpose: The contraceptive pill is an effective and safe method of preventing pregnancy. The progestins used for contraception either are components of a combined hormonal contraceptive (tablets, patches or vaginal rings) or are used alone in progestin-only formulations. Progestin-only contraceptives are available as daily oral preparations, subcutaneous or intramuscular injectables (every 1-3 months), subdermal implants (every 3-5 years) and intrauterine systems (every 3-5 years). Long-acting progestins are highly effective in typical use and have a very low risk profile and few contraindications.Material and Methods: A new progestin-only, oestrogen-free contraceptive, drospirenone, in a dosage of 4 mg/day in a 24/4 regimen, has received regulatory approval in the USA and the EU. The molecule has antigonadotropic, antimineralocorticoid, antiestrogenic and antiandrogenic properties.Results: The regimen was chosen to improve the bleeding profile; maintain plasma oestradiol levels at those of the early follicular phase, to avoid hypoestrogenism; and preserve efficacy even with a missed pill, as drospirenone has a half-life of 30-34 h.Conclusions: Clinical studies have shown good efficacy, very low cardiovascular side effects and a favourable bleeding pattern, as well as maintenance of ovulation inhibition after scheduled 24 h delays in pill intake.

Multicenter, phase III trials on the contraceptive efficacy, tolerability and safety of a new drospirenone-only pill.

INTRODUCTION: Approximately 100 million women currently use combined oral contraceptives. Combined oral contraceptives use is associated with increased risk of venous thromboembolic events and cardiovascular disease. Progestin-only pills do not increase the risk of venous thromboembolic events, stroke and myocardial infarction but are associated with a poor cycle control. A novel estrogen-free pill containing only drospirenone (DRSP) was developed to improve bleeding pattern, tolerability and acceptance without increasing venous thromboembolic events risks in contraception. MATERIAL AND METHODS: Two prospective, multicenter Phase III studies in healthy women aged 18-45 years were performed to demonstrate the efficacy and safety of a drospirenone-only pill in a regimen of 24 days of 4 mg of drospirenone tablets followed by 4 days of placebo. A total of 1571 women (14 329 exposure cycles) were analyzed: 713 patients in the 13-cycle study 1 with 7638 exposure cycles and 858 patients in the 9-cycle study 2 with 6691 exposure cycles. The primary endpoint was the overall Pearl index, calculated for each study separately, and for both pooled. As main secondary efficacy endpoint, the "method failure Pearl index" including all pregnancies during "perfect medication cycles" was evaluated. EudraCT registration numbers: 2010-021787-15 & 2011-002396-42. RESULTS: Calculations on pooled studies 1 and 2 with 1571 patients gave an overall Pearl index (based on 14 329 cycles) of 0.7258 (95% CI 0.3133 to 1.4301). No single case of deep vein thrombosis or pulmonary embolism and only one case of hyperkalemia were reported. Additional information such as laboratory parameters, body mass index, bodyweight, heart rate and blood pressure showed no statistically significant changes due to the treatment. CONCLUSIONS: This is the first report of a new drospirenone-only oral contraceptive providing clinical efficacy similar to combined oral contraceptives, with a good safety profile, and favorable cycle control.

Prospective observational study to evaluate the efficacy and safety of the pollen extract Sérélys® in the management of women with menopausal symptoms.

Safety concerns or contraindications to the use of hormones have resulted in a rise of the use of herbal medicinal products for the management of menopausal symptoms. The pollen extract Sérélys® represents, due to its ingredients and mode of action, a new and innovative alternative for the management of these symptoms. The aim of the present study was to demonstrate the efficacy and safety of Sérélys®. A prospective, open, observational, and multicentre study was performed on 104 menopausal women. The patients received over 3 months the pollen extract Sérélys® containing the extracts PI82 and GC Fem in a dosage of twice 160 mg extract and 5 mg vitamin E. Using a validated menopausal rating score, the improvement of menopausal symptoms was recorded. A significant decrease of different menopausal symptoms was observed between the starting point of the study and after 12 weeks (p < .0001). Hot flashes were reduced by 48.5%, sleep disturbance by 50.1%, depressive mood by 51.2%, irritability by 47.9%, fatigue by 47.8%, vaginal dryness by 39.63% and muscles and joint pain by 27.4%. The pollen extract Sérélys® reduced significant menopausal symptoms showing a very low side effect profile.

A multicenter, double-blind, randomized trial on the bleeding profile of a drospirenone-only pill 4 mg over nine cycles in comparison with desogestrel 0.075 mg.

PURPOSE: A typical compliance problem in the use of traditional progestin-only pills is the irregular bleeding pattern and the strict daily intake. Desogestrel 75 mg has a 12-h missed-pill window; however, its poor cycle control limits a more common use. METHODS: A drospirenone (DRSP)-only pill was developed to improve the bleeding profile. SETTING: A phase III study in healthy women aged 18-45 years was performed to compare the bleeding profile and safety of a DRSP-only pill in a regime of 24 days of 4 mg of DRSP tablets followed by 4 days of placebo versus desogestrel 0.075 mg per day continuously over nine cycles. POPULATION: A total of 858 women with 6691 drospirenone and 332 women with 2487 desogestrel treatment cycles were analyzed. MAIN OUTCOME MEASURES: The primary end point was the proportion of women with unscheduled bleeding/spotting in each cycle from cycles 2 to 9 and cumulative in cycles 2-4 and cycles 7-9. RESULTS: In each cycle, up to cycle 7, the proportion of women with unscheduled bleeding was statistically significantly lower in the DRSP group than in the DSG group (p = 0.0001, Chi-square test). CONCLUSIONS: This report describes the improvement in bleeding profile of women using the new DRSP-only oral contraceptive in comparison to DSG, providing a better quality of live and adherence to the contraceptive method. EudraCT Registration Number: 2011-002396-42.

In vitro evaluation of microbial adhesion to a contraceptive vaginal ring with a new polymer composition.

Objective: The aim of the study was to evaluate in vitro the amount of Candida albicans and Lactobacillus acidophilus adhering to the surface of Ornibel, a contraceptive vaginal ring with a new polymer composition, in comparison with NuvaRing. Methods: Ornibel and NuvaRing were tested for adhesion of microorganisms in vitro. The vaginal rings were aseptically sectioned into 1 cm segments. Suspensions of C. albicans (1-2 × 107 colony-forming units [CFU]/ml) and L. acidophilus (1-2 × 108 CFU/ml) were prepared and incubated either in monoculture or as co-culture with the ring segments. After incubation, adherent C. albicans and L. acidophilus were quantified by plate counting. Results: In monoculture, the measured amount of adhesion of C. albicans on the ring surface was significantly lower with Ornibel compared with NuvaRing (p = 6.77 × 10-5), while the adherence of L. acidophilus did not differ between the two rings. Similarly, when co-incubated with C. albicans, the number of adhering L. acidophilus microorganisms was significantly lower with Ornibel compared with NuvaRing (p = .018) . This reduction also resulted in significantly lower levels of adhering L. acidophilus in co-culture compared with L. acidophilus when incubated alone (p = .003). Conclusion: The study demonstrates that the adherence of C. albicans, as well as that of L. acidophilus when co-cultured with C. albicans, is lower with the Ornibel vaginal ring compared with NuvaRing. These in vitro findings warrant future human trials using molecular techniques to assess the vaginal microbiota composition and to establish whether Ornibel can support vaginal health.

Identification and prediction of the fertile window with a new web-based medical device using a vaginal biosensor for measuring the circadian and circamensual core body temperature.

Fertility awareness-based (FAB) methods represent a term that includes all family planning methods that are based on the identification of the fertile window. They are based on the woman's observation of physiological signs of the fertile and infertile phases of the menstrual cycle. The first approach consists basically in symptothermal methods accompanied by cervical mucus measurements and clinical menstrual cycling data recording. The second most often used methods are the urinary measurement of E3G and luteinizing hormone (LH) with a personalized computer system. Hence these systems lack the efficacy of the continuous circadian and circamensual measurement of the core body temperature. Only this approach enables the accurate detection of the ovulation during the fertile window. A new medical device called OvulaRing has been developed to fill this gap. In the present study, the system and its first clinical results are presented. OvulaRing is a medical device used just like a tampon. The device is a vaginal ring of evatane that contains an integrated biosensor. This sensor measures continuously every 5 min the core body temperature throughout the entire cycle. This device allows a circadian and circamensual intravaginal exact measurement. With this system, 288 measurements are created per day. The system can detect retrospectively and predict prospectively the fertile window of the users. One hundred and fifty eight women aged between 18 and 45 years used this medical device in an open non-randomized clinical study for 15 months. A total of 470 cycles could be recorded and were able for analysis. By the same time in a subgroup of patients, hormonal assessments of LH, follicle-stimulating hormone, estradiol and progesterone as well as vaginal ultrasound were performed in parallel between the 9th and the 36th day of the cycle. The validation error due to software errors was 0.89% for the retrospective analysis; that means that the accuracy for the detection of the ovulation was 99.11%. Accuracy of 88.8% for a window of 3 days before ovulation, the day of ovulation and the 3 days after ovulation was achieved for the prospective analysis. In the subgroup of woman with recorded pregnancies, it could be shown that after 3.79 months of use (median) pregnancies were observed. In 67.72% in up to 3 months, in 16.36% between 3 and 6 months of use, in 7.27% between 7 and 9 months, in 5.45% between 10 and 12 months and in 1.82% between 13 and 15 months of use of the system. With this new web-based system, a precise determination of the fertile window even in women with ultralong cycles (>35 days) could be detected independently of their personal live circumstances. Exact determination of the fertile window is herewith possible so that OvulaRing represents an evolution in the FAB method for the cycle diagnosis of women with regular, irregular or anovulatory menstrual cycles.

Pharmacokinetic bioequivalence, safety and acceptability of Ornibel®, a new polymer composition contraceptive vaginal ring (etonogestrel/ethinylestradiol 11.00/3.474 mg) compared with Nuvaring® (etonogestrel/ethinylestradiol 11.7/2.7 mg).

OBJECTIVE: To show the clinical development of Ornibel® (ExeltisHealthcare, Spain) a contraceptive vaginal ring manufactured with a new polymer composition and containing etonogestrel/ethinylestradiol, compared to Nuvaring® (MSD, Spain). SUBJECTS AND METHODS: Randomised, single dose, 2-period, 2-sequence, 2-stage crossover, comparative bioavailability study conducted in 40 healthy female subjects. All subjects received both treatments for 28 days in each of two periods, separated by a 28 days washout. Ornibel® contains etonogestrel/ethinylestradiol 11.00/3.47 mg and Nuvaring® contains etonogestrel/ethinylestradiol 11.7/2.7 mg, both rings delivering 120/15 µg/day. For the calculation of pharmacokinetic parameters, 37 blood samples were collected up to 840 h after each ring insertion to quantify plasma concentrations of etonogestrel and ethinylestradiol using a validated MS/MS-HPLC. Safety was assessed by adverse events recording, clinical laboratory and vital signs and tolerability by vaginal examination. Acceptability was investigated by a 5-point scale questionnaire. RESULTS: Bioequivalence was demonstrated in the first stage as the 94.12% Confidence Intervals of the primary parameters laid within the 80-125% acceptance range for both etonogestrel (Cmax: 96.81-112.20%; AUC0-504h: 98.71-108.61%; AUC0-t: 100.14-109.10%) and ethinylestradiol. (Cmax: 105.91-120.62%; AUC0-504h: 105.47-114.59%; AUC0-t: 108.31-117.61%). During the first day of use a burst effect was observed with Nuvaring®, with significantly higher level of ethinylestradiol (Cmax0-24h ratio: 78.34%, 94.12CI: 73.55-83.45%). Both products were well tolerated and accepted, without significant differences between them. CONCLUSION: Ornibel® is bioequivalent to Nuvaring® in terms of efficacy, safety, tolerability and acceptability. The new polymer composition provides Ornibel® with more stability and gradual hormonal release during the first day of use, particularly for ethinylestradiol.

Drospirenone as estrogen-free pill and hemostasis: coagulatory study results comparing a novel 4 mg formulation in a 24 + 4 cycle with desogestrel 75 µg per day.

INTRODUCTION: A novel estrogen free contraceptive pill, with drospirenone 4 mg in a dosing regimen of 24 + 4, has been developed with a pearl-index of 0.51 (95% CI 0.1054; 1.4922). The aim of the following study was to determine if 4 mg DRSP has an impact on coagulation factors and thrombotic risks in comparison with desogestrel 75 µg. PATIENTS AND METHODS: Thirty-nine patients received 4 mg DRSP 24 + 4 d and 29 desogestrel 75 µg per day continuously during nine complete cycles. Following hemostatic parameters were evaluated: Apc resistance, Antithrombin III, Protein C reactivity, Factor VII, Factor VIII, and d-Dimer. RESULTS: Factor VII decreased from 1.123 to 1.066 in the DRSP group and from 1.241 to 1.034 in the desogestrel group (p = 0.0088). The difference in change of mean Protein C activity from baseline to endpoint was -0.0332 in the DRSP versus -0.157 in the desogestrel group (p = 0.0249). d-Dimer values dropped in the DRSP group from baseline values of 264.9-215.0 ng/mL, whereas in the desogestrel group there was a rise from 201.4 ng/mL to 281.5 ng/mL. DISCUSSION: DRSP 4 mg was not associated with any meaningful changes on hemostatic parameters, indicating a lack of effect on hemostasis.

Prevalence of cumulative cardiovascular risk factors among women of childbearing age in France: Results of the GYNRISK® survey.

Global burden of cardiovascular disease is growing worldwide among women, particularly in younger women. Corresponding increases in the number and severity of cardiovascular risk factors (CVRF) associated with a greater impact in women could explain this increase in incidence. The prevalence of CVRF remains poorly known within young women, especially their cumulative prevalence. This study aimed to determine the prevalence of traditional and emerging CVRF, including female-specific CVRF, in young French women of childbearing age (16-45 years). The GYNRISK® survey aimed to analyse the magnitude and cumulation of CVRF. Two thousand women, representative of the general population, completed a self-administered, computer-assisted web interviewing survey. Results highlighted the high prevalence of traditional CVRF (73.8 % with at least one CVRF). Modifiable CVRF were also particularly high, especially overweight/obesity (31.3 %), tobacco/cannabis consumption (24.0 %), sedentary lifestyle (55.4 %), low fruit and vegetable intake (83.6 %), and poor health literacy (87.2 %). Additionally, a high prevalence of accumulated CVRF was reported, with 37.8 % of young French women having ≥2 traditional CVRF, 69.6 % having ≥1 traditional and ≥1 emergent CVRF, and 73.3 % having ≥1 traditional in addition to ≥1 lifestyle associated CVRF. Among women receiving combined hormonal contraception (CHC), 34.0 % had a contraindication for CHC due of the presence of CVRF (single or cumulative) according to recommendations. GYNRISK® survey highlighted the need for more data in this understudied population of young women. Increasing knowledge, screening, prevention, and information, with targeting on modifiable CVRF must be a priority to reduce women cardiovascular burden.

Pro-Resolving Inflammatory Effects of a Marine Oil Enriched in Specialized Pro-Resolving Mediators (SPMs) Supplement and Its Implication in Patients with Post-COVID Syndrome (PCS).

OBJECTIVES: This study aimed to evaluate the eicosanoid and pro-resolutive parameters in patients with Post-COVID Syndrome (PCS) during a 12-week supplementation with a marine oil enriched in specialized pro-resolving mediators (SPMs). PATIENT AND METHODS: This study was conducted on 53 adult patients with PCS. The subjects included must have had a positive COVID-19 test (PCR, fast antigen test, or serologic test) and persistent symptoms related to COVID-19 at least 12 weeks before their enrolment in the study. The following parameters were evaluated: polyunsaturated fatty acids EPA, DHA, ARA, and DPA; specialized pro-resolving mediators (SPMs), 17-HDHA, 18-HEPE, 14-HDHA, resolvins, maresins, protectins, and lipoxins. The eicosanoids group included prostaglandins, thromboxanes, and leukotrienes. The development of the clinical symptoms of fatigue and dyspnea were evaluated using the Fatigue Severity Scale (FSS) and the Modified Medical Research Council (mMRC) Dyspnea Scale. Three groups with different intake amounts were evaluated (daily use of 500 mg, 1500 mg, and 3000 mg) and compared to a control group not using the product. RESULTS: In the serum from patients with PCS, an increase in 17-HDHA, 18-HEPE, and 14-HDHA could be observed, and a decrease in the ratio between the pro-inflammatory and pro-resolutive lipid mediators was detected; both differences were significant (p < 0.05). There were no differences found between the three treatment groups. Fatigue and dyspnea showed a trend of improvement after supplementation in all groups. CONCLUSIONS: A clear enrichment in the serum of the three monohydroxylated SPMs could be observed at a dosage of 500 mg per day. Similarly, a clear improvement in fatigue and dyspnea was observed with this dosage.
