ABSTRACT

Relevance: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. The prevalence rates of PCOS depend on the diagnostic criteria used and the characteristics of the population sample, and in the general population of women of reproductive age, the prevalence of the syndrome ranges from 6-9% to 19.9% [1,2]. According to modern criteria adopted by the consensus in Rotterdam, then systematically updated by ESHRE / ASRM (2014), the presence of two of the three criteria in a patient simultaneously allows to diagnose PCOS if other pathological conditions are excluded (thyroid pathology, congenital adrenal hyperplasia, adrenogenitalsyndrome, androgen-secreting tumors, Itsenko-Cushing syndrome). Modern international diagnostic criteria include the following signs: (1) signs of polycystic ovaries according to information from pelvic ultrasound investigation (the presence of more than 10 follicles in each ovary);(2) oligo-anovulation;(3) clinical (presence of hirsutism) or biochemical (increased androgen levels) development of ovarian hyperandrogenism [3, 4]. Polycystic ovary syndrome is closely related to many diseases, including metabolic syndrome. Although insulin resistance is an important risk factor for metabolic syndrome and other diseases associated with PCOS, hyperandrogenismmay also be an independent risk factor for type 2 diabetes, obesity, cardiovascular disease (CVD), and metabolic syndrome in female patients. Obesity is the most common symptom in PCOS patients (33-88%), which has a large impact on fertility and can lead to adverse effects such as menstrual irregularities, anovulation, infertility and abortion. Therefore, weight management in early PCOS is essential to improve fertility and quality of life. Hyperandrogenism plays a decisive role in abdominal obesity in obese women during adolescence, adulthood and menopause [5]. Although some studies have shown a negative association between plasma androgen levels (A4, DHEA and DHEAS) and obesity [6,7]. But the mechanism of how androgens affect fat cells in women is poorly understood. A number of observations show that among obese women with PCOS, metabolic disorders associated with insulin resistance and obesity, in many cases, play a more important role in the mechanism of anovulation in PCOS than excess androgens. In recent years, it has been established that in PCOS there is a frequent combination of hyperandrogenism and insulin resistance. With insulin resistance, there is a decrease in the response of insulin-sensitive tissues to the hormone insulin with its sufficient level in the blood. Insulin resistance is found in 30-70% of patients with PCOS who are overweight or obese, and in patients with normal body weight it occurs in 20-25% of cases. The above facts, as well as our own observations, prompted us to analyze the studied women of fertile age with impaired reproductive system against the background of overweight and obesity. Considering the above, the aim of this study was to identify the relationship between insulin resistance and reproductive disorders in women with overweight and obesity. Material and research methods. The study included 123 women with clinical development of HA and impaired reproductive function, who consulted the consultative clinic of the RSSPMC of Obstetrics and Gynecology of the Ministry of Health of the Republic of Uzbekistan. The criteria for inclusion in the main group were: age of women from 18 to 35 years (average age was 25.8 .. 3.28 years), absence of pregnancy, body mass index over 25 kg / m2. Exclusion criteria from the main group: type 1 and 2 diabetes, pituitary tumors, hypogonadotropichypogonadism, congenital adrenal hyperplasia, hypothyroidism, severe somatic pathology. All patients who applied for the consultation underwent: (1) Collection of anamnestic information. (2) Measurement of anthropometric indicators (height, weight, waist and hip circumference) and assessment of body hair growth using the Ferriman-Hallway scale. (3) Body mass index was

ABSTRACT

Since its inception in 2019 from China, the novel Coronavirus has caused an unprecedented havoc in the economic and public health sector. Many countries were forced to close their borders and cross-border interactions in order to limit the spread of the disease. Furthermore, many economic and commercial activities were adversely affected as many businesses had to close. The only ones that the pandemic spared were the ones providing essential services. By March 2020, many public healthcare facilities had already been overrun. Other governments devised alternative means of managing significant cases of COVID-19, such as introducing home-based care to give room for more critical cases to be taken care of in intensive care units. It is imperative to identify the disease's risk factors to mitigate the unexpected devastation caused by the SARS-CoV-2. Global epidemiological results indicate that men, especially the elderly, are more susceptible to Coronavirus infection. The number of reported Coronavirus cases varies by gender, and this disparity continues to grow in favor of male participants until they reach the age of 60. Other studies have also established that men more than women are susceptible to coronavirus infection. Further, male patients diagnosed with coronavirus infection were shown to have an elevated mortality rate. SARS-CoV-2 is the Covid-19 pathogen that is transmitted via respiratory globules, through indirect or direct interaction. Evaluation of the genome has revealed that SARS-CoV-2 is 79% similar to SARS-CoV-2;they employ ACE2 receptors to attack cells, meanwhile it has been established that TMPRSS2 promotes ACE2, therefore causing more severe reactions in comparison to the other types of coronaviruses. Studies describe ACE2 as a gateway for viruses to enter cells. It is directly associated with the COVID-19 clinical symptoms. Research has shown that TMPRSS2 and ACE2 are expressed in the male reproductive system tract and testis and are controlled by testosterone. Thus, the male reproductive system has all the mechanism needed to bid SARs-CoV-2, and these possibilities raise the capability of ACE2 and TMPRSS2 as potential vectors of COVID-19. This review examines how the novel Coronavirus find its way into the human cells through known receptors such as ACE2, antibody Fcy R, etc. The examination is also done on the mechanisms of its spike proteins transition with the help of proteases such as cathepsins, Furin, and TMPRSS2. The study reviewed six articles selected based on PRISMA criteria.
