Therefore, it is imperative to identify reliable, non-invasive biomarkers of the disease. The aim of this study was to analyse the concentrations of fibronectin and type IV collagen in peritoneal fluid and plasma to assess their role as potential biomarkers in the diagnosis of endometriosis. Fibronectin and collagen IV protein levels were assessed by surface plasmon resonance imaging (SPRi) biosensors with the usage of monoclonal antibodies. All patients enrolled in the study were referred for laparoscopy for the diagnosis of infertility or chronic pelvic pain (n = 84). The study group included patients with endometriosis confirmed during surgery (n = 49). The concentration of fibronectin in the plasma (329.3 ± 98.5 mg/L) and peritoneal fluid (26.8 ± 11.1 μg/L) in women with endometriosis was significantly higher than in the control group ...

However, it is uncertain whether their physiological variation related to the regular menstrual cycle affects the CV system. We studied changes in the hemodynamic profile and body’s water content and their relation to sex hormone concentration in healthy women during the menstrual cycle. Material and methods: Forty-five adult women were examined during the early follicular, late follicular, and mid-luteal phases of the same menstrual cycle. The hemodynamic profile was estimated non-invasively by cardiac impedance while water content was estimated by total body impedance. Results were compared with repeated measures ANOVA with post-test, if applicable. Results: There were no significant changes in most hemodynamic and water content parameters between the menstrual cycle phases in healthy women. Left ventricular ejection time differed significantly among phases of the menstrual cycle, with shorter values in ...

The aim of this study was to compare levels of ZEB1 and ZEB2 in the peritoneal fluid and plasma between patients with and without endometriosis in order to assess their utility in the diagnostic process. Plasma and peritoneal fluid samples were collected from 50 patients with and 48 without endometriosis during planned surgical procedures in eight clinical centers. Quantitative ZEB1 and ZEB2 levels analyses were performed using a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). No significant differences were observed in ZEB1 levels in any of the subanalyses nor any differences regarding ZEB2 levels between patients with and without endometriosis. Plasma ZEB2 levels were significantly higher among patients with infertility compared to fertile women (16.07 ± 12.70 ng/L vs. 12.07 ± 11.92 ng/L...

Material and methods: The report was prepared by the Polish Society of Reproductive Medicine and Embryology (PTMRiE) and the Fertility and Sterility Special Interest Group of the Polish Society of Gynaecologists and Obstetrics (SPiN PTGiP) as a part of the European IVF Monitoring program (EIM) for the European Society of Human Reproduction and Embryology (ESHRE). Reporting was voluntary and the data was not subject to external control. The report presents the availability and structure of infertility treatment services, the number of procedures, their effectiveness and complications. Results: Between 2013 and 2016, a total of 106,718 treatment cycles using ART [64,413 classical in vitro fertilization and in vitro fertilization with intracytoplasmic sperm injection (IVF + ICSI), 36,041 frozen embryo replacements (FER)] and 51,405 IUI were recorded. The clinical pregnancy rates per embryo transfer in IVF, ICSI and FER were 38.3%, 38.1% and 32.4%, respectively. The effectiveness of IUI with husband/partner's semen (IUI-H) was 11.1% and with donor semen (IUI-D) 16.7%. Multiple delivery rates were 11.3% and 6.2% in IVF + ICSI and IUI, respectively. The most common complication was the ovarian hyperstimulation syndrome (OHSS) (0.34%). Conclusions: PTMRiE and SPiN PTGiP report is the only national study documenting Polish reproductive medicine. The results of infertility treatment effectiveness in Poland are comparable with the European data, complications are less frequent than in other countries. The low percentage of multiple pregnancies, and so perinatal complications, is especially valuable. However, due to the lack of a central database and register, the possibility of external control and monitoring of pregnancies and births is limited. Thus, a fully reliable assessment of the treatment quality in our country is not possible.

SUMMARY ANSWER MAR services, and hence treatments for infertile couples, were stopped in most European countries for a mean of 7 weeks. WHAT IS KNOWN ALREADY With the outbreak of COVID-19 in Europe, non-urgent medical care was reduced by local authorities to preserve health resources and maintain social distancing. Furthermore, ESHRE and other societies recommended to postpone ART pregnancies as of 14 March 2020. STUDY DESIGN, SIZE, DURATION A structured questionnaire was distributed in April among the ESHRE Committee of National Representatives, followed by further information collection through email. PARTICIPANTS/MATERIALS, SETTING, METHODS The information was collected through the questionnaire and afterwards summarised and aligned with data from the European Centre for Disease Control on the number of COV...

Each year brings new information, so, having collected the experience of three scientific societies, we present contemporary recommendations concerning PCOS diagnostics and treatment. In adult female diagnosis, we still use the Rotterdam criteria, which is two out of three of the follwing characteristics: a) ovulation abnormality, b) clinical or biochemical hyperandrogenism, and c) polycystic ovaries. In the case of teenagers, diagnostic criteria are as follows: menstruation disturbances two years after menarche and clinical or biochemical hyperandrogenism. The presence of polycystically abnormal ovaries is not necessary. The consensus paper presents the threats resulting from imperfect diagnostic methods applied in PCOS (hyperandrogenism diagnostics, ultrasound examination of ovaries). Suggested therapy includes personalised schemes according to the dominant PCOS phenotype, i.e. metabolic, hyperandrogenic, or reproductive ones.

Prior studies suggest that PCOS can be associated with mood and psychiatric disorders. The purpose of this study is to examine the prevalence of any psychiatric disorder in women with PCOS. Methods We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through February 08, 2017 for studies that examined the prevalence of any psychiatric disorder in adolescents or adults with a clinical or biochemical diagnosis of PCOS. We used a random-effects model to generate pooled estimates and 95% confidence intervals (CI). Results We included 57 studies reporting on 172,040 patients. The majority of studies addressed depression and anxiety. Studies had fair methodological quality although most estimates were unadjusted. Women with PCOS were more likely to have a clinical diagnosis of depression (odds ratio (OR), 2.79; 95% CI, 2.23-3.50), anxiety (OR, 2.75; 95% CI, 2.10-3.60), bipolar disorder (OR, 1.78; 95% CI, 1.43-2.23) and obsessive compulsive disorder (OCD) (OR, 1.37; 95% CI 1.22-1.55), but not social phobia or panic disorder. Using various scales, the severity of symptoms of depression, anxiety, obsessive compulsive disorder, and somatization disorders were higher compared to women without PCOS. Conclusions PCOS is associated with an increased risk of diagnosis of depression, anxiety, bipolar disorder, and obsessive compulsive disorder. It is associated with worse symptoms of depression, anxiety, OCD, and somatization. Screening for these disorders to allow early intervention may be warranted.

The aim of the study was to evaluation of influence of the oral contraceptive pill on the endocrinologic and metabolic parameters in women with PCOS. Forty nine PCOS women (aged 23,9 +/- 3,5 [mean +/- SD]) without any other diseases were included into the study. Oral contraceptives (0,02 mg ethynylestradiol + 0,15 mg desogestrel) were administered for 6 months. Hormonal and biochemical analyses were performed with specific assays at the beginning and after 6 month-therapy BMI, insulin sensitivity index (ISI) and QUICKI were calculated. Statistical analysis was performed using Wilcoxon test. All patients completed 6-month therapy and no severe side effects were reported during the study. A significant reduction in testosterone (T) concentrations was observed (p<0.005). We recorded...

All these factors can lead to endothelial dysfunction and impaired coagulation processes. Metformin effectively treats hyperinsulinemia in women with PCOS. However, clinical trials assessing influence of metformin on endothelium and fibrinolysis are limited. Therefore, the objective of this study was to prospectively assess the effects of a 6-month metformin therapy on body mass index (BMI), insulin sensitivity and coagulation/fibrinolysis markers in hyperinsulinemic women with PCOS. Thirty hyperinsulinemic PCOS women (aged 26.0 +/- 3.7 [mean +/- SD]) without any additional disorders were included into the study. Metformin was administered at a dose of 1700 mg daily for 6 months. Serum plasminogen activator inhibitor type 1 (PAI-1) and tissue plasminogen activator (t-PA) concen...

This study was undertaken to evaluate and compare the effectiveness of presacral neurectomy (PSN) in the presence and absence of endometriosis. Twenty-three women with midline CPP (age 30.3 +/- 7.9, range 21-46) unresponsive to medical therapy were recruited to the study. Endometriosis was absent in seven and present in sixteen subjects. Laparoscopic PSN using a harmonic scalpel was performed in all subjects; simultaneous excision of endometriotic lesions was also carried out in subjects with endometriosis. Intensity of dysmenorrhoea and pelvic pain was measured by visual analogue pain scale (VAPS) at 3 and 12 months postoperatively. Dysmenorrhoea decreased at 3 months by 75% (P = 0.018) in those without endometriosis and by 78% (P = 0.001) in those with endometriosis. At 12-months, dysmenorrhea increased i...

In vitro, statins decrease proliferation and steroidogenesis of ovarian theca-interstitial cells. Objective: The study objective was to compare effects of two treatments of PCOS: simvastatin plus oral contraceptive pill (OCP) vs. OCP alone. Design: In a prospective, crossover trial, 48 women with PCOS were randomized to either simvastatin plus OCP for 12 wk followed by OCP alone for an additional 12 wk, or to OCP alone for 12 wk and, subsequently, simvastatin plus OCP for an additional 12 wk. Evaluations were performed at baseline, after 12 wk (crossover), and after 24 wk. Data were analyzed using a random effects model. Setting: The study was conducted in an academic medical center. Primary Outcome: Serum total testosterone was the primary outcome measure. Results: Total testosterone decreased by 38% after Statin ϩ OCP, whereas OCP alone led to a 26% decrease; the statin-attributable effect was significant (P Ͻ 0.004). Free testosterone declined by 58% after Statin ϩ OCP, significantly more than the 35% decline after OCP alone (P ϭ 0.006). Hirsutism decreased by 8.1% after Statin ϩ OCP, a greater effect than the 4.7% decrease after OCP alone (P ϭ 0.02). Statin decreased LH, but not FSH or prolactin. Statin ϩ OCP decreased total and low-density lipoprotein cholesterol by 7.5% and 20%, respectively. OCP alone led to a 5% increase of total cholesterol without effect on low-density lipoprotein cholesterol. Statin prevented OCP induced increase of triglycerides. C-reactive protein decreased by 45% after Statin ϩ OCP, a significantly different effect (P ϭ 0.006) than a 6% increase after OCP alone. Soluble vascular cell adhesion molecule 1 decreased by 18% after Statin ϩ OCP, a greater decline than the 10% decrease after OCP alone (P ϭ 0.01). Conclusions: Simvastatin improved endocrine/clinical aspects of PCOS and had beneficial effects on lipid profile and markers of systemic inflammation.

Metformin and, more recently, statins have been shown to improve endocrine and metabolic aspects of PCOS. Objective: The aim of the study was to compare effects of simvastatin and metformin on PCOS. Design: In a prospective trial, women with PCOS (n ϭ 136) were randomized to simvastatin (S), metformin (M), or simvastatin plus metformin (SM) groups. Evaluations were performed at baseline and after 3 months. Setting: The study was conducted at an academic medical center. Primary Outcome: The change of serum total testosterone was measured. Results: The study was completed by 113 subjects. Total testosterone decreased significantly and comparably in all groups: by 17.1, 13.6, and 15.1%, respectively, in the S, M, and SM groups. Significant decreases were also observed in all groups with respect to body mass index, C-reactive protein, and soluble vascular cell adhesion molecule-1. DHEAS declined significantly only in the S group. None of the treatments were associated with significant changes in LH or FSH. Total cholesterol and low-density lipoprotein cholesterol significantly declined only in S and SM groups. Conclusions: Simvastatin treatment was superior to metformin alone, whereas a combination of simvastatin and metformin was not significantly superior to simvastatin alone.

Objective: The aim of the study was to evaluate long-term effects of simvastatin and metformin on PCOS. Design: Women with PCOS (n ϭ 139) were randomized to simvastatin (S), metformin (M), or simvastatin plus metformin (SM) groups. Evaluations were performed at baseline and at 3 and 6 months. Setting: The study was conducted at a university medical center. Primary Outcome: We measured the change of serum total testosterone. Results: Ninety-seven subjects completed the study. Total testosterone decreased significantly and comparably in all groups: by 25.6, 25.6, and 20.1% in the S, M, and SM groups, respectively. Both simvastatin and metformin improved menstrual cyclicity and decreased hirsutism, acne, ovarian volume, body mass index, C-reactive protein, and soluble vascular cell adhesion molecule-1. Dehydroepiandrosterone sulfate declined significantly only in the S group. Total cholesterol and low-density lipoprotein cholesterol significantly declined only in the S and SM groups. Ongoing reduction of ovarian volume, decreased hirsutism, acne and testosterone were observed between 0 and 3 months as well as between 3 and 6 months. Improvement of lipid profile, C-reactive protein, and soluble vascular cell adhesion molecule-1 occurred only during the first 3 months of treatment, with little change thereafter. Treatments were well tolerated, and no significant adverse effects were encountered. Conclusions: Long-term treatment with simvastatin was superior to metformin. Improvement of ovarian hyperandrogenism continued throughout the duration of the study. (J Clin Endocrinol Metab 96: 3493-3501, 2011) P olycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting up to 10% of women of reproductive age (1-3). Among various definitions of PCOS that have been proposed, the most common diagnostic criteria include hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology. The etiol-ogy of PCOS remains unknown, and in view of the heterogeneous nature of the syndrome, it is likely to consist of a constellation of different disorders sharing various pathophysiological features. However, one of the most prominent features of PCOS is abnormal ovarian function characterized by excessive androgen production by a hy

We investigated serum FABP4 and RBP4 responses to insulin sensitizing and lipid lowering therapies in polycystic ovary syndrome (PCOS). Sixty-two healthy, untreated women with PCOS (age 25.1 ± 3.6 years, BMI: 24.0 ± 4.7 kg/m(2)) were randomized to metformin (n = 24), simvastatin (n = 20) or metformin plus simvastatin (n = 18) for 3 months. Anthropometric measures, fasting blood tests and oral glucose tolerance tests (OGTT) were obtained at the baseline and the end. At the baseline serum FABP4 correlated with obesity (BMI: r = 0.63, p &amp;amp;amp;amp;amp;amp;amp;amp;lt; 0.001), insulin resistance (fasting insulin: r = 0.44, p = 0.0002; QUICKI: r = -0.30, p = 0.02; OGTT-insulin sensitivity index: r = -0.27, p = 0.04), dyslipidemia (HDL: r = -0.26, p = 0.03) and hyperandrogenemia (free-testosterone: r = 0.23, p = 0.03; SHBG: r = -0.28, p = 0.03); while RBP4 correlated with total-cholesterol (r = 0.33, p = 0.009). Multiple regression analysis indicated that t best predictors of serum FABP4 and RBP4 were BMI (β = 1.02, p = 0.0003) and total cholesterol (β = 2326, p = 0.01), respectively. Simvastatin, alone or with metformin did not affect serum FABP4 or RBP4. Serum FABP4 related to the obesity, insulin resistance and inflammation while RBP4 related to lipids. Insulin sensitizing and lipid lowering therapies did not affect FABP4 or RBP4 levels in PCOS.
