Over the last decade, huge achievements have been made in the fields of neurophysiology, molecular endocrinology, and biochemistry, as well as in the successful translation of clinical research into diseases into clinical practice. As regards female reproduction, most of the advances made in this area were achieved in gonadal axis regulation, regulation of behavior through sex steroids, reproductive genetics, preservation of ovarian reproductive function, steroid profiling, and metabolic and overall reproductive outcomes. The coming years are expected to bring further understanding of the relationships between nutrition, energy metabolism, and reproductive function and to succeed in identifying new genetic markers linked to adverse metabolic and unfavorable cardiovascular outcomes in women. From our perspective, future research in the field of female reproduction should be directed toward doing research into genetic reproductive abnormalities and neuroendocrine diseases, pathophysiology, long-term health outcomes for oligo/amenorrhea, hyperandrogenism, and ovulatory dysfunction. It is additionally expected that a better understanding will be gained of the endocrinology of the placenta and of pregnancy, the role of the microbiome in female reproduction, the role of insulin sensitizers, anti-obesity and anti-diabetic drugs, and various advances in the prevention of ovarian damage caused by various oncology therapies, while new therapeutic options for the treatment of infertility, including kisspeptin, will be developed. © 2018, Hellenic Endocrine Society.

About 1% of ovarian tumors that comprise testicular cell types can cause hyperandrogenism followed by characteristic virilization. Androgenic group of tumors originated mainly from sex-cord stromal ovarian tumors are including steroid cell tumors, Leydig tumors, granulosa cell tumors, Sertoli cell tumors, Sertoli-Leydig cell tumors, gonadoblastomas, and some other rare forms as ovarian metastases from neuroendocrine tumors. Germline or somatic mutations in some genes like DICER1, STK11, and FOXL2 are associated with the development of some sex cord-stromal ovarian tumors. Basal serum testosterone concentrations above 7 nmol/L could indicate an androgen-secreting tumor. Other ovarian and adrenal androgens should be determined and functional endocrine testing including low-dose dexamethasone suppression test, gonadotrophin-releasing hormone (GnRH) agonist test, imaging methods, and selective venous sampling should be performed. Surgery is the first-line treatment for most of the tumors. Women who are not good surgical candidates could benefit from use of GnRH agonist to control hyperandrogenism. In some cases, chemotherapy and/or radiation therapy is required while some tumors respond on antiangiogenic agents used alone or in combination with chemotherapy. Metabolic implications and long-term outcomes of ovarian androgen-secreting tumors are unknown and require more detailed follow-up in multicentric and longitudinal clinical studies. © 2019 S.

Introduction: Basal insulin analogues offer persons with type 2 diabetes mellitus (T2DM) adequate glycemic control combined with a favorable safety profile. BASAL-BALI—a prospective, noninterventional, multicenter disease registry—assessed the effectiveness and safety of basal insulin analogues in adult Serbians with T2DM previously inadequately controlled on other insulin types. Methods: The primary objective was to assess the reduction in glycated hemoglobin (HbA1c) from basal insulin analogue initiation to the end of a 6-month observation period. Data collection was performed at three study visits: baseline, 3 months, and 6 months. All treatments and procedures were performed at the physicians’ discretion. Results: In total, 460 subjects were included. Mean diabetes duration was 11.6 ± 6.6 years. Late complications of diabetes were present in 67% of subjects and comorbidities in 85%. After 6 months, the mean reduction in HbA1c was 1.8% (p < 0.01 vs. baseline); body weight (mean reduction of 0.9 kg, p < 0.01), waist circumference (1.5 cm, p < 0.01), and BMI (0.2 kg/m2, p < 0.01) were also reduced. A total of 49.1% of subjects reached their individualized HbA1c treatment target, and 42.0% met the composite HbA1c and fasting plasma glucose (FPG) target. The incidence of symptomatic hypoglycemia was reduced from 96.3% in the 6 months prior to initiating basal insulin analogues to 15.4% over the 6-month treatment period. Conclusion: Introducing basal insulin analogues in persons with T2DM previously inadequately controlled on other insulin types can significantly improve glycemic control and reduce the risk of hypoglycemia, without adversely affecting body weight.

Background: Systemic inflammatory response syndrome (SIRS) changes cortisol dynamics and indicates dissociation between the adrenal cortex and the hypothalamo-pituitary unit. The aim of this study was to assess the cortisol response after stimulation with ACTH1-24 in patients with SIRS at admission to the Respiratory Intensive Care Unit (RICU) and seven days later. Methods: Fifty-four subjects were included in the study, and SIRS was defined according to the Consensus Conference criteria from 1992. Severity of the disease was determined using the APACHE II score, and organ dysfunction using the SOFA score. Low-dose (1 μg) ACTH test (LDT) was performed in all patients, and cortisol was determined along with basal ACTH. Data were analyzed using parametric and nonparametric tests and regression analysis. The results are presented as mean ± standard deviation, and P<0.05 was considered statistically significant. Results: There were no differences in cortisol values between the two LDTs. Cortisol increment lower than 250 nmol/L during the LDT was found in 14/54 (25.9%) subjects at the onset of SIRS. Five out of 54 (9.6%) patients died within 7 days from the onset of SIRS. Female sex and maximal cortisol response (Δ max) on LDT predicted the duration of hospitalization in RICU, while APACHE II and SOFA scores best predicted the duration of hospitalization, mortality outcome as well as overall survival outcome. Conclusions: A difference was found in Δ max at the diagnosis of SIRS and seven days later. Δ max, and primarily the clinical scores APACHE II and SOFA predicted the outcomes of hospitalization and overall survival. © 2016 Jelica Bjekić-Macut et al.

It is supposed that women with polycystic ovary syndrome (PCOS) are prone to develop cardiovascular disease as a consequence of multiple risk factors that are mostly related to the state of insulin resistance and consequent hyperinsulinemia. In the present study, we evaluated insulin signaling and glucose transporters (GLUT) in cardiac cells of dihydrotestosterone (DHT) treated female rats as an animal model of PCOS. Expression of proteins involved in cardiac insulin signaling pathways and glucose transporters, as well as their phosphorylation or intracellular localization were studied by Western blot analysis in DHT-treated and control rats. Treatment with DHT resulted in increased body mass, absolute mass of the heart, elevated plasma insulin concentration, dyslipidemia and insulin resistance. At the molecular level, DHT treatment did not change protein expression of cardiac insulin receptor and insulin receptor substrate 1, while phosphorylation of the substrate at serine 307 was increased. Unexpectedly, although expression of downstream Akt kinase and its phosphorylation at threonine 308 were not altered, phosphorylation of Akt at serine 473 was increased in the heart of DHT-treated rats. In contrast, expression and phosphorylation of extracellular signal regulated kinases 1/2 were decreased. Plasma membrane contents of GLUT1 and GLUT4 were decreased, as well as the expression of GLUT4 in cardiac cells at the end of androgen treatment. The obtained results provide evidence for alterations in expression and especially in functional characteristics of insulin signaling molecules and glucose transporters in the heart of DHT-treated rats with PCOS, indicating impaired cardiac insulin action. © 2014 Elsevier Ltd.

Polycystic ovary syndrome (PCOS) is a common metabolic and reproductive disorder in women. An increased cardiovascular risk has to be anticipated in PCOS as it is a metabolically unstable condition. Among cardiovascular risk factors, dyslipidemia is certainly the most persistent and highly prevalent. Predominant observation is an elevation of LDL cholesterol in all PCOS patients. Decreased concentrations of HDL cholesterol are found in obese PCOS from the third decade of life onwards while triglycerides start to rise from the second decade of life. PCOS is associated with oxidative stress, namely increased production of free radicals followed by decreased serum antioxidant levels and antioxidant enzyme activity. Broad range of endocrine and metabolic disturbances like obesity, hyperinsulinemia as well as dyslipidemia might be responsible for PCOS- associated oxidative stress. Therapeutic interventions in PCOS women based on lifestyle modification as well as use of insulin sensitizers did not show significant effect on dyslipidemia. Statins are considered to be a group of promising agents that are safe and effective in improving total cholesterol, LDL cholesterol and triglycerides, and possess antioxidant activity. Supplementation with omega- 3 fatty acids, α- lipoic acid and N- acetylcysteine is considered to have an anti- inflammatory and antioxidant effect and to improve dyslipidemia and insulin sensitivity in PCOS women. © 2013 by S.

Background: This study aimed to calculate the frequency of elevated liver enzymes in hospitalized patients with coronavirus disease 2019 (COVID-19) infection and to test if liver enzyme biochemistry levels on admission could predict the computed tomography (CT) scan severity score of bilateral interstitial pneumonia. Methods: This single-center study comprised of 323 patients including their demographic data, laboratory analyses, and radiological findings. All the information was taken from electronic health records, followed by statistical analysis. Results: Out of 323 patients, 115 of them (35.60%) had aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) over 40 U/L on admission. AST was the best predictor of CT scan severity score of bilateral interstitial pneumonia (R2 = 0.313, Adjusted R2 = 0.299). CT scan severity score in the peak of the infection could be predicted with the value of AST, neutrophils, platelets, and monocytes count (R2 = 0.535, Adjusted R2 = 0.495). Conclusion: AST, neutrophils, platelets, and monocytes count on admission can account for almost half (49.5%) of the variability in CT scan severity score at peak of the disease, predicting the extensiveness of interstitial pneumonia related to COVID-19 infection. Liver enzymes should be closely monitored in order to stratify COVID-19 patients with a higher risk of developing severe forms of the disease and to plan the beforehand step-up treatment. © 2022 by the authors.

Background: Polycystic ovary syndrome (PCOS) is a cardiometabolic disorder whose features include dyslipidemia, increased oxidative stress (OS, oxy) and chronic inflammation. The aim of this study was to investigate the ability of a summary score for dyslipidemia, OS and inflammation (the DOI score) to discriminate PCOS patients from healthy individuals and to evaluate the effect of obesity on individual scores and the DOI score in patients. Methods: Lipid status parameters, OS status parameters (advanced oxidation protein products; total oxidative status; prooxidant-antioxidant balance; malondialdehyde; total protein sulphydryl groups and paraoxonase 1 activity) and CRP were measured in 114 patients and 50 controls using standardised assays. The DOI score was calculated as the sum of dyslipidemia, oxy and inflammation scores, determined as Z-score values for every subject in relation to the controls. Results: PCOS patients had significantly higher oxy-score compared to controls (P<0.001). In addition, the DOI score was significantly higher in PCOS patients (P<0.001) as the dyslipidemia (P<0.05) and inflammatory scores (P<0.001) were greater. According to ROC analysis, the oxy-score showed better diagnostic accuracy in discriminating PCOS patients compared to the DOI score (AUC>0.9, P<0.01). Furthermore, obesity affected the risk scores in patients, especially the DOI score (significantly higher DOI scores in such patients, P<0.001). Conclusion: PCOS patients had greater dyslipidemia, chronic inflammation and OS compared to controls and could be segregated using all four scores. Our data suggest that weight gain could be the common factor responsible for induction and propagation of dyslipidemia, OS and inflammation in PCOS patients. © 2018 Iva Perović Blagojević et al., published by Sciendo.

Polycystic ovary syndrome (PCOS) is a common endocrine disease in women during reproductive age. It was shown that PCOS women are with high risk for dyslipidemia, glucose intolerance, type 2 diabetes and metabolic syndrome. These factors are considered to represent traditional risk factors for the occurrence of cardiovascular disease. Observed increased risk for hypertension in PCOS women seems to be associated with insulin resistance and hyperinsulinemia. Both conditions interfere with the endothelium-dependent vasodilatation mechanisms causing vascular muscle wall hypertrophy. Obesity and insulin resistance are considered key factors for the alteration of blood pressure in PCOS women. Higher cardiovascular risk is implicated in PCOS with aging and its consequent association with both systolic and diastolic blood pressure. The elements of renin-angiotensin-aldosterone system (RAAS) have an impact on endothelial dysfunction as a marker of cardiovascular damage that could be modified is women with PCOS. Androgens and components of RAAS are involved in the process of atherogenesis in PCOS women. Therefore, it is hypothesized that spironolactone treatment could ameliorate endothelial dysfunction in PCOS women. Recently it was shown that telmisartan, angiotensin II receptor antagonist poses insulin-sensitizing capacity to activate PPAR gamma and mediate favorable metabolic and reproductive effects in hypertensive PCOS women. © 2020 Bentham Science Publishers.

Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy among women during reproductive age. PCOS is characterised by hyperandrogenaemia, hyperinsulinaemia, and deranged adipokines secretion from the adipose tissue. In addition to the reduced insulin sensitivity, PCOS women exhibit β-cell dysfunction as well. Low birth weight and foetal exposure to androgens may contribute to the development of the PCOS phenotype during life. Further metabolic complications lead to dyslipidaemia, worsening obesity and glucose tolerance, high prevalence of metabolic syndrome, and greater susceptibility to diabetes. PCOS women show age-related existence of hypertension, and subtle endothelial and vascular changes. Adverse reproductive outcomes include anovulatory infertility, and unrecognised potentiation of the hormone-dependent endometrial cancer. The main therapeutic approach is lifestyle modification. Metformin is the primary insulin-sensitising drug to be used as an adjuvant therapy to lifestyle modification in patients with insulin resistance and impaired glucose tolerance, as well as in those referred to infertility treatment. Thiazolidinediones should be reserved for women intolerant of or refractory to metformin, while glucagon-like peptide 1 analogues has a potential therapeutic use in obese PCOS women. Randomised clinical trials and repetitive studies on different PCOS phenotypes for the preventive actions and therapeutic options are still lacking, though. © 2017 Elsevier B.V.

Purpose: Polycystic ovary syndrome (PCOS) is an endocrine, metabolic, and reproductive disorder which, according to the Rotterdam criteria, affects up to 24% of women of childbearing age. Although the prevalence of infertility in this subpopulation of women is high, the optimal treatment has not been fully established yet. Insulin resistance is considered to be an important mechanism involved in the development of PCOS; hence, the aim of this narrative review is to present an overview of the current pharmacological insulin-sensitizing treatment modalities for infertile women with PCOS. Methods: A MEDLINE and PubMed search for the years 1990–2023 was performed using a combination of keywords. Clinical trials with insulin sensitizers used for infertility treatment as well as analyses of systematic reviews and meta-analyses were evaluated. When deemed necessary, additional articles referenced in the retrieved papers were included in this narrative review. Results: Several insulin-sensitizing compounds and various therapeutical protocols are available for infertility treatment of women with PCOS. Metformin is the most common adjuvant medication to induce ovulation in infertile women with PCOS and is more frequently administered in combination with clomiphene citrate than on its own. Recently, inositol and glucagon-like peptide-1 (GLP-1) receptor agonists have emerged as possible options for infertility treatment in PCOS. Conclusion: The future of medical treatment of PCOS women with infertility lies in a personalized pharmacological approach, which involves various compounds with different mechanisms of action that could modify ovarian function and endometrial receptivity, ultimately leading to better overall reproductive outcomes in these women. © The Author(s), under exclusive licence to Hellenic Endocrine Society 2023.

Objective: There are limited data on cardiometabolic risk factors and the prevalence of metabolic syndrome (MetS) across the different PCOS phenotypes in Caucasian population. Lipid accumulation product (LAP) is a clinical surrogate marker that could be used for evaluation of MetS in clinical practice. The aim of the study was to analyze metabolic characteristics and the ability of LAP to predict MetS in different PCOS phenotypes. Design: Cross-sectional clinical study analyzing 365 women with PCOS divided into four phenotypes according to the ESHRE/ASRM criteria, and 125 healthy BMI-matched controls. Methods: In all subjects, LAP was determined and MetS was diagnosed according to the National Cholesterol Education Program/Adult Treatment Panel III (NCEP-ATP III), the International Diabetes Federation (IDF) and the Joint Interim Statement (JIS) criteria. Logistic regression and ROC curve analyses were used to determine predictors of MetS in each PCOS phenotype. All analyses were performed with age and BMI adjustment. Results: All PCOS phenotypes in comparison to controls had higher prevalence of MetS assessed by NCEP-ATP III criteria, and only classic phenotypes when IDF and JIS criteria were used. All phenotypes had the same prevalence of MetS irrespective of used definition. LAP and exhibited the highest diagnostic accuracy and was an independent predictor of MetS in all phenotypes. Conclusion: LAP is an independent and accurate clinical determinant of MetS in all PCOS phenotypes in our Caucasian population. All PCOS phenotypes, including non-classic ones, are metabolically challenged and with cardiovascular risk, particularly phenotype B. © 2016 The authors Published by Bioscientifica Ltd.
