Materials and methods. 28 patients with GE of I-II degrees of prevalence (R-AFS) were included in the study. Control group consisted of 11 healthy women. All the patients underwent laparoscopy and hysteroscopy with histological examination of ovarian tissue, peritoneum and endometrium; patients with GE also were performed histological examination of endometrioid of heterotopies. Definition of levels of kisspeptin, FSH, LH, prolactin, AMH, estradiol, estrone, androgens (free testosterone, dehydroepiandrosterone – DHEA) in peripheral blood in healthy women and in patients with GE were conducted by ELISA on the 2nd and 8th days of menstrual cycle. Immunohistochemical method was used to evaluate expression of metastine (kisspeptin) and its receptor in ovarian tissue, peritoneum, in endometrioid heterotopies and in endometrium. Results. Hormonal survey has revealed that the level of kisspeptin in peripheral blood was reliably higher compared to its level in the control group. Immunohistochemical study found that in patients with GE area of expression of KISS and KISS1R receptor in endometrium was reliably lower when compared with these values in the control group. In the foci of endometrioid heterotopies, which were located on the pelvic peritoneum, it was observed a reliable increase in protein КІЅЅ1 expression and receptor KISS1R compared to fragments of intact peritoneum. The area of expression of receptor KISS1R in endometrioid heterotopies was reliably higher than the area of its expression in endometrium of patients with GE and in endometrium of women of the control group. Direct correlation between the area of protein expression (KISS) in endometrium with level kisspeptin on the 8th day of menstrual cycle in peripheral blood (rs = 0,90) has been revealed. It has been determined that the level of kisspeptin on the 2nd day of menstrual cycle in peripheral blood correlates with the area of expression of receptor KISS1R in peritoneum (rs = 0,57). A direct correlation between the area of expression of receptor KISS1R in peritoneum with the level of kisspeptin on the 8th day of menstrual cycle in serum has been found (rs = 0,90). Conclusion. The obtained data show a definite role of kisspeptin in pathogenesis of genital endometriosis. It can be assumed that the increase in the level of metastine (kisspeptin) in peripheral blood and increased expression of KISS1 in endometrioid heterotopies and especially its receptor KISS1R are compensatory-adaptive response aimed at deterrence of further spread of endometriosis. The obtained results justify the need to continue research in this direction for a deeper understanding of pathogenesis of the disease and possible use of kisspeptin as biomarker for non-invasive diagnostics as well as potential targeted therapy of GE.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. It is known that kisspeptin stimulates activity of GnRH neurons and secretion of FSH and LH, thus disruption of interaction between kisspeptin and its receptor leads to anovulation. The aim of the study was to investigate the role kisspeptin in the pathogenesis of polycystic ovary syndrome. Materials and methods. The study included 14 patients with classic phenotype of PCOS and 11 healthy women of the control group. All the patients underwent laparoscopy and hysteroscopy with histological examination of ovarian tissue and endometrium. Determination of kisspeptin, FSH, LH, prolactin, AMH, estradiol, estrone, androgens (free testosterone and dehydroepiandrosterone sulfate) levels in peripheral blood in healthy women and patients with PCOS was performed by ELISA on the 2d and 8th days of menstrual cycle. Progesterone levels were investigated on the 18th-22d days of menstrual cycle. Expression of kisspeptin and its receptor in ovarian tissue and endometrium was estimated using immunohistochemical method. Results. Level of kisspeptin in peripheral blood of patients with PCOS tends to increase compared to its level in the control group, but the found difference was not reliable. Direct correlation between serum level of kisspeptin and levels of LH, free testosterone and DHEA-S was revealed in patients with PCOS. Immunohistochemical study in patients with PCOS showed a significant increase in the area of expression of КІЅЅ1 and KISS1R receptor in endometrium and in ovarian biopsies compared to these values in the control group. Conclusion. The obtained data show a definite role of kisspeptin in pathogenesis of polycystic ovary syndrome, but further research is needed.

Tasks of investigation were concluded the characterization of insulin resistence (IR) and hormonal features in patients with prediabetes and influence of diet or metformin on the course of pregnancy and perinatal complications. There were examined 61 womans. The OGTT, definition of insulin levels in plasma and index IR were performed in all patiens. OGTT and index IR were normal in 14 womans (control group I). OGTT was normal but index IR was impared in 33 womans (group IR - II). From this group 22 womans were treated with diet (II A group) and 11 womans treated with metformin (IIB group). OGTT and index IR were abnormal in 14 womans (impared OGTT - III group), they were treated with metformin. Dose of metformin was 1500 mg/d, threatment was continueted for 3-4 manths. Conclusion: Used indexes IR basal and two hour after glucose load were significant in definition of normal and decreased insulin sensitivity (IR). Presence of IR is accompanied by high level of free testosterone in blood without impared secretion of ovarian and suprarenal androgens. There was impared sensitivity of endometrium of secretory stage. The frequency of obstetric and perinatal complications in patients receiving diet not differ from patients treated with metformin. There was only a tendercy to low frequency of threatening miscarriages befor 12 weeks of gestations in paitiens receiving metformin. Development of GDM was observed in 13,1 % of patiens only with presence of IR. The use of metformin in pregravidal stage preserved the development of macrosomia in offsprings of patients with prediabetes.

Background. The role of androgens in a woman has not been fully appreciated. Currently, there is no clear and gene­rally accepted definition of the concept of androgen deficiency in women by analogy with that in men. The purpose of the study was to investigate the clinical and diagnostic aspects of testoste­rone deficiency in women of fertile age. Materials and methods. The study included 60 women with testosterone deficiency without other concomitant pathology. The average age of the patients was 28.3 years. The control group consisted of 20 healthy women. The patients were divided into three groups based on their body mass index (BMI). The first group consisted of 20 overweight women (BMI 25–29.9 kg/m2), the second group — 20 women with first-degree obesity, and the third group — 20 women with second-degree obesity. Results. On the 14th day of the ovarian-menstrual cycle, the patients from the first group showed a tendency towards a decrease in the basal levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol, and progesterone against the background of significant hypoandrogenaemia. Patients with obesity (II degree) showed a significant decrease in basal levels of LH, FSH, estradiol, progesterone against the background of significant hypoandrogenaemia. The correlation analysis revealed a direct relationship between testosterone deficiency and obesity. Thus, the lowest testosterone values were found in patients of the third group (< 0.05 nmol/l). At the same time, the testosterone level in the patients of the first and second groups was also significantly reduced — from 0.02 to 0.05 nmol/l, respectively. The levels of dehydroepiandrosterone and 17-hydroxycorticosteroids were significantly reduced, especially in the third group — 0.3 μg/ml and 0.1 nmol/l, respectively. Conclusions. Most women of reproductive age with testosterone deficiency have hypomenorrhea with low free testosterone. A direct correlation was established between testosterone deficiency and the degree of obesity in women with androgen deficiency.

AbstractThe role of innate immunity in COVID-19 is not completely understood. Therefore, this study explored the impact of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection on the expression of Pattern Recognition Receptors (PRRs) in peripheral blood cells and their correlated cytokines. Seventy-nine patients with severe COVID-19 on admission, according to World Health Organization (WHO) classification, were divided into two groups: patients who needed mechanical ventilation and/or deceased (SEVERE, n = 50) and patients who used supplementary oxygen but not mechanical ventilation and survived (MILD, n = 29); a control group (CONTROL, n = 17) was also enrolled. In the peripheral blood, gene expression (mRNA) of Toll-like receptors (TLRs) 3, 4, 7, 8, and 9, retinoic-acid inducible gene I (RIGI), NOD-like receptor family pyrin domain containing 3 (NLRP3), interferon alpha (IFN-α), interferon beta (IFN-β), interferon gamma (IFN-γ), interferon lambda (IFN-λ), pro-interleukin(IL)-1β (pro-IL-1β), and IL-18 was determined on admission, between 5–9 days, and between 10–15 days. Circulating cytokines in plasma were also measured. When compared to the COVID-19 MILD group, the COVID-19 SEVERE group had lower expression of TLR3 and overexpression of TLR4.

Information on menstrual cycle dependent variation of tumor markers in healthy women is a subject of diagnostic efficiency and has an impact in elucidating the normal function of these markers. In this study midfollicular and midluteal concentrations of serum CEA, AFP, CA 19-9, CA 125, CA 15-3 and their relations with LH, FSH, prolactin, estradiol and progesterone were evaluated during ovulatory cycles in a group of 23 healthy female individuals. Samples were collected on the 7th and 21st day of the same menstrual cycle. Tumor marker and hormone concentrations were determined with chemiluminescence or electrochemiluminescence EIA methods. A significant phase-dependent difference was observed for CA 15-3, midluteal concentrations (mean ± SEM; 26.33 ± 1.56 U/ml) higher than the midfollicular (mean ± SEM; 19.27 ± 1.49 U/ml) concentrations (p < 0.001). But an obvious difference for other tumor markers investigated did not exist. Significant correlations of follicular and luteal CA 125 levels with body mass index of the subjects were observed (r:0.52, p < 0.05 and r:0.57, p < 0.005, respectively).CA 15-3 antigen is a product of the MUC-1 gene which is expressed in abundance by endometrial epithelial cells in the secretory phase of the menstrual cycle which may be the potential source of variability. The association of CA 125 levels with obesity suggests a possible role of adipose tissue in CA 125 metabolism. In conclusion our data suggest that in healthy women serum CA 15-3 levels are significantly elevated in the midluteal phase of the menstrual cycle compared to midfollicular phase. Therefore, consideration of menstrual cycle dependent variability for CA 15-3 appears indicated in interpretation of individual results.

The study values, through electromyography (emg), the stripped urethral sphyncter activity in women with stress incontinence (USI). 10 women with USI and 5 healthy women -control group- underwent urogynecologic examination, urodynamic examination and urethral electromyography examination. The endurance and extension of tension were took in the consideration. 9 women with USI had EGM showing denervation/renervation nervous damage, supported by potential&rsquo;s wideness and length higher than control group (&gt;300&mu;V), either during relax or cough, and the trace&rsquo;s absence of the interference with voluntary contraction. Only one woman with USI showed an EGM compatible with myogen damage: values &lt;100 &mu;V in all traces and negative anamnesis for risk factors. The Authors emphasize the role of EMG as a particular exam to study in deep the causes of urinary incontinence helpful to identify basic disorders of USI.

The role of prolactin in the maintenance of the corpus luteum of pseudopregnancy was studied in the golden hamster. Nine groups of seven to fourteen animals each received 1 mg bromocriptine at 11.00 h on days 1, 2 or 3 of pseudopregnancy (three groups for each day). On each day of treatment with bromocriptine, one group of hamsters was injected with bovine prolactin 4 h before bromocriptine, and one group received prolactin 4 h before bromocriptine for three consecutive days following treatment with bromocriptine. One group received bromocriptine only. These nine groups were compared with a control group of animals given 0·85% saline instead of bromocriptine and prolactin. Peripheral blood samples were taken from all hamsters at 11.00 h on days 3, 4, 5 and 6 of pseudopregnancy and plasma levels of progesterone were determined by radioimmunoassay. Luteolysis, indicated by a decline in progesterone level by 24 or 48 h after treatment with bromocriptine, occurred in all hamsters given bromocriptine alone, whether it was administered on day 1, 2 or 3. Pretreatment with a single dose of prolactin did not mitigate the bromocriptine-induced fall in progesterone. In the majority of cases, pretreatment with prolactin plus daily doses of prolactin maintained the progesterone at levels not different from saline-treated hamsters. These data suggest that prolactin is a necessary luteotrophin during early pseudopregnancy without which luteolysis ensues.
