Neuropeptides coordinate and regulate physiological processes in all animals. Alarin is a 25 amino acid neuropeptide which promotes the secretion of luteinizing hormone (LH). It has been known that serum luteinizing hormone levels are increased in women with polycystic ovary syndrome. Therefore, purpose of this was to examine the association of circulating gonadotropin secretions, and alarin with women with polycystic ovary syndrome, and to compare these findings with those of control subjects in an effort to better understand the pathophysiology of PCOS. 28 participants with a diagnosis of PCOS with normal weight and 28 participants with a diagnosis of PCOS with obese and 28 control group participants were included in this case-control study. Hormone profiles of the participants (alarin, insulin, estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone sulfate (DHEA-SO4 ), lipid profiles total testosterone, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride, cholesterol) and fasting blood sugar (FBS) values were measured. Results: Serum androgens were elevated in the PCOS. Blood LH was also elevated (P < 0.05) but was higher in PCOS than Control. Patients with PCOS had an increased alarin compared with controls. LH/FSH ratio and Alarin /FSH ratio were greater than 2.1, 2.4, respectively. The blood alarin levels were significantly correlated with the serum LH levels (r=0.492, p=0.002) and the LH/FSH ratios (r=0.450, p<0.001) and Alarin/ FSH ratios. The FSH/LH and alarin /FSH ratio were elevated in the PCOS. Based on these results, the FSH/LH and Alarin /FSH ratio appears to be a useful marker of PCOS.

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders of women in the childbearing period. However, its pathophysiology is still unclear. Certain polymorphisms of the luteinizing hormone/choriogonadotropin receptor (LHCGR) genes may lead to changes in the bioactivity of this hormone. The important functional role of LHCGR in the metabolism of androgen and ovulation, the LHCGR gene variant, may be related to the risk of PCOS. AIM: The aim of this study was to evaluate the association between LHCGR Ins18LQ gene polymorphism and PCOS. METHODS: A case–control study was performed in women with PCOS and non-PCOS from May 2019 to October 2019 in HFC IVF Center. We included 50 women with PCOS and 50 healthy controls. Polymorphism of the LHCGR (ins18LQ) gene was genotyped using polymerase chain reaction-restriction fragment length polymorphism. RESULTS: From this study, we found that there was no significant difference in the proportion of ages between the groups (p > 0.05). There were significant differences in the characteristics of body mass index, FSH level, LH level, and LH/FSH ratio between the PCOS and control groups (p < 0.05). We also found that the proportion of heterozygote variant non-ins/ins was higher in the PCOS group compared to the control group, but there was no significant difference between the polymorphisms of the non-ins and non-nonins variants between the PCOS and control groups (p = 0.269). The frequency of ins alleles was higher in the PCOS group compared to the control group. CONCLUSION: There was no significant association between LHCGR ins18LQ gene polymorphism and PCOS.

Background: Polycystic ovary syndrome is known to be the most common hormonal disorder in women of reproductive age. Current evidence shows that regulatory proteins secreted from the adipose tissue called adipokines may have a role in polycystic ovary syndrome. We planned to investigate the role of endotrophin that has never been researched in polycystic ovary syndrome before and its correlation with other metabolic parameters and adipokines such as adiponectin and ghrelin in patients with polycystic ovary syndrome. Methods: Forty-three women ( n: 43) with polycystic ovary syndrome and 43 ( n: 43) women as a control group were enrolled in this cross-sectional study. Serum levels of endotrophin, adiponectin, and ghrelin levels were measured with the enzyme-linked immunosorbent assay method. High-density lipoprotein cholesterol, low-density lipoprotein cholesterol, total cholesterol levels, luteinizing hormone/follicle-stimulating hormone ratio, total testosterone, and triglyceride levels were measured. Homeostasis model assessment for insulin resistance index, body mass index, Ferriman Gallwey Score, and waist-to-hip ratio were also evaluated. Results: Total testosterone, homeostasis model assessment for insulin resistance, C-reactive protein, luteinizing hormone/follicle-stimulating hormone ratio, and triglyceride levels were higher in patients with polycystic ovary syndrome ( p < 0.01). No difference was detected between the groups in terms of body mass index, Ferriman Gallwey Score, waist-to-hip ratio, total cholesterol, low-density lipoprotein, and high-density lipoprotein levels ( p > 0.05). We did not observe any significant difference in adiponectin and ghrelin levels between the groups ( p > 0.05). Patients with polycystic ovary syndrome had significantly higher endotrophin levels ( p < 0.01). According to our regression analyses [area under the curve: 0.973 (0.935–1.000), 95% confidence interval, 95.2% sensitivity, and 100% specificity], it was shown that endotrophin greater than 92 ng/ml and homeostasis model assessment for insulin resistance greater than 2.5 might be good predictors for polycystic ovary syndrome diagnosis. Conclusion: We demonstrated that endotrophin level is higher in patients with polycystic ovary syndrome and may have predicted polycystic ovary syndrome with increased homeostasis model assessment for insulin resistance index. There was no significant difference in adiponectin and ghrelin levels in the polycystic ovary syndrome group. Endotrophin may have a role in polycystic ovary syndrome etiology rather than other adipokines.

BACKGROUND: The diagnosis of polycystic ovary syndrome (PCOS) is not an easy procedure, as the signs and symptoms are heterogeneous and of undefined aetiology.AIM: This study is aimed to evaluate serum anti-Mullerian hormone (AMH) level and luteinizing hormone (LH)/folic stimulating hormone (FSH) ratio in women with PCOS in Sudan and to assess the diagnostic efficiency for the diagnosis of PCOS.METHODS: In a case-control study, Serum AMH, LH, FSH was measured in the early follicular phase from Sudanese patients (N = 230) with PCOS and100 controls. The LH/FSH ratio was calculated, and its diagnostic power was evaluated by receiver operating characteristic curves.RESULTS: The means of serum AMH, serum LH level and LH/FSH ratio of the test, were significantly increased in the test group compared to the control group (P-value < 0.000). The AMH sensitivity, specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) were found to be 83%, 99%, 99%, and 72% respectively. Serum AMH was considered adequate measures for the diagnosis of PCOS; its level showed an area under the ROC curve of 0.98 (95% confidence, P-value < 0.000). The best compromise between 98% specificity and 90% sensitivity was obtained with a cut-off value of 3.3 ng/mL for PCOS diagnosis. There was no correlation between age, body mass index (BMI) and AMH level in the test group.CONCLUSIONS: The Serum AMH level and LH/FSH ratio were higher in patients than in control. However AMH level has better discriminative power and good diagnostic potency for the diagnosis of the PCOS among Sudanese women.

Background and Objective: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting 10–15 % of women in reproductive age. The objective was to evaluate the effect of irisin in the etiology of obese patient with PCOS. Study Design and Methods: The study design its a case control study. This study involved fifty obese ladies (50) with confirmed diagnosis of PCOS. The second group served as control group and included forty apparently normal (non-polycystic ovary) obese ladies (40). The following main parameters were measured: Fasting serum levels of total Cholesterol, triglyceride, high density lipoprotein-cholesterol, low density lipoprotein– cholesterol, glycohaemoglobin (HbA1c%), Insulin , Testosterone, FSH, serum LH and Irisin. Results: The median serum Irisin was significantly higher among PCOS cases (119.1 ng/ml) compared to healthy controls (74.7 ng/ml). The median serum FSH was significantly higher among PCOS cases (6.52 ng/ml ) compared to controls (4.72 ng/ml). Serum LH was obviously higher among PCOS cases (6.88 ng/ml) compared to controls (6.08 ng/ml). The mean pulse rate, blood WBC count and serum VLDL were significantly higher (71.6/min, 8.3 mg/dl and 22.5 mg/dl respectively) in cases with PCOS compared to controls (67.5/min, 7.2 mg/dl and 18.5 mg/dl respectively). Conversely, the serum HDL was significantly lower among PCOS cases (43.8 mg/dl) compared to controls (48.4 mg/dl), serum testosterone showed statistically non-significant differences. Conclusion: Data of the present study showed that serum Irisin was significantly higher among PCOS cases. These findings suggest important role of irisin as a biomarker for PCOS and an important factor in the development of PCOS.

ABSTRACT There has been a surge of interest in recent years in studying the changes of serum melatonin concentrations in disorders that are associated with insulin resistance such as diabetes mellitus type 2 and polycystic ovary syndrome (PCOS). AIM: The present study was designed to investigate the day-time and night-time levels of serum melatonin and the cortisol rhythm in women with PCOS and compare them with those of healthy women. PATIENTS AND METHODS: This is a case-control study which included 30 women with PCOS and 25 healthy women. All hormonal measurements in both the study group and controls were carried out between days 3 and 5 counted from the beginning of the last regular menstrual cycle; they included serum levels of melatonin and cortisol at 03:00 a.m and 08:00 a.m, total testosterone (T), dehydroepiandrosterone sulfate (DHEA-S), luteinizing hormone (LH), follicle stimulating hormone (FSH), and immunoreactive insulin at 08:00 a.m. RESULTS: Women with PCOS were found to have a significantly higher melatonin level at 08:00 a.m. and smaller mean night-day difference in the concentrations of melatonin in comparison with those of healthy women (natural log (Ln) night-day difference 0.60 ± 0.10 pg/ml versus 1.15 ± 0.14, p < 0.002). Melatonin to cortisol ratios at 03:00 a.m. and 08:00 a.m. showed no statistically significant differences between the two groups (Ln melatonin/ cortisol 03:00 a.m., 1.01 ± 0.06 versus 1.05 ± 0.05; Ln melatonin/cortisol at 08:00 a.m., 0.62 ± 0.01 versus 0.56 ± 0.03, p > 0.05). CONCLUSION: The results we obtained about the changes of melatonin in women with PCOS could help in elucidating the complex pathophysiological pattern of this disease.

Alarin is a newly identified peptide hormone. It is implicated that alarinplays roles in regulation of energy metabolism and hypothalamo-pituitary-gonadal axis. Polycystic Ovary Syndrome (PCOS) is a common reproductive and metabolic disease in women during reproductive ages. Over-secretion of Luteinizing Hormone (LH) causes hyperandrogenism in women with PCOS. The purpose of the study was to determine the comparison of alarin levels in women with or without PCOS as well as to investigate the relationship between alarin and LH. Eighty-four women with PCOS and 84 age- and BMI- matched controls were recruited in this cross-sectional study. Circulating alarin levels were assessed via ELISA method. The hormonal and metabolic parameters of the recruited subjects were also determined. The circulating levels of alarin in PCOS subjects were higher than controls (6.11 ± 1.91 vs. 3.93 ± 1.60 ng/ml, P <0.001). Alarin showed a positive correlation with insulin resistance marker, BMI, LH and androgens. Moreover, alarin levels were elevated in women with PCOS having insulin resistance compared to those PCOS women without insulin resistance. In both control and PCOS groups, overweight subjects showed an elevation in circulating levels of alarin with respect to normal weight subjects. In the present study, Alarin level with the highest tertile dosage comparing to alarin level with the lowest tertile dosage could highly increase the probability of PCOS risk prevalence in women. Elevated alarin levels in women with PCOS were associated with not only LH and metabolic parameters but also high probability of having PCOS risk independently.

Abstract Background The polycystic ovary syndrome (PCOS) is the most common endocrine associated with insulin resistance, even in the absence of overweight. The global lipid profile of the follicular fluid in PCOS with normal weight as yet has not been investigated. The objection of this pilot study was to explore the changes of lipids in the follicular fluid of PCOS with normal weight. Methods Follicular fluid samples were collected from patients who underwent IVF, including normal-weight women without PCOS (control group, n = 10) and normal-weight women with PCOS (PCOS group, n = 8). A lipidomic analysis was performed by high performance liquid chromatography/ mass spectrometry (HPLC-MS). Multidimensional statistical analysis was performed to disclose the global differences between the two groups. Further, differential lipid analysis between the two groups was performed by Fold Change Analysis (FC Analysis) and T-test to screen potential markers. Results All 812 species of 32 subclasses of lipids were identified by lipidomics analysis. 108 kinds of lipids were considered as the potential candidate differential metabolites with the score of variable importance in the project (VIP) more than 1 by the orthogonal partial least squares discriminant analysis. 32 lipids were significantly different between the PCOS group and the control group simultaneously with FC > 1.5 or FC < 0.67, p-value < 0.05 and VIP value > 1. These differential species of lipid belong to lipid subclasses including triglycerides (TG), phosphatidylethanolamines (PE) and phosphatidylinositols (PI). Conclusion The identified differential lipids in the follicular fluid may be considered as candidate biomarkers as well as therapeutic targets of PCOS with normal-weight.

Background. PCOS is one of the most common endocrinological pathologies in women of reproductive age, manifested by a wide range of clinical manifestations. There are many unresolved issues related to the pathogenesis, diagnosis and treatment of this pathological condition in different periods of reproductive age. Aim the objective of the study was to identify the features of the functioning of the pituitary-ovarian system in women with PCOS at different periods of reproductive age. Methods. Study was performed in 20172019 at the FSPSI SCFHHRP, and involved women aged 1845 years. The study groups included women (a group of women with PCOS and a control group) in the follicular phase from 1 to 12 days of the menstrual cycle. As a result of the survey, a group of 44 women with PCOS and a group of 56 healthy women were formed. PCOS was diagnosed according to ESHRE/ASRM criteria (Rotterdam, 2003). Next, subgroups of women in early reproductive age from 35 to 45 years were formed: a group of women with PCOS (n = 29) and a control group (n = 22). And groups of women in late reproductive age from 35 to 45 years were formed: a group of women with PCOS (n = 15) and a control group (n = 34). Conducted: questionnaire survey, general and gynecological examination, ultrasound examination of the pelvic organs, laboratory tests, statistical data analysis. Results. In women with polycystic ovary syndrome of early reproductive age (1835 years), we detected an increase in the level of testosterone by 2 times, DHEA-S by 1.3 times, 17-OH-progesterone by 2 times, sex steroid-binding globulin by 1.4 times, in comparison with control group. The ratio of luteinizing hormone to follicle-stimulating hormone increased by 52%. In women with polycystic ovary syndrome of late reproductive age (3545 years), we detected an increase in the level of testosterone by 1.5 times, 17-OH-progesterone by 1.9 times, luteinizing hormone by 1.4 times, sex steroid-binding globulin by 1.6 times, in comparison with control group, without any significant differences in DHEA-S. At the same time, the ratio of luteinizing hormone to follicle-stimulating hormone increased by 60%. Conclusion. The hormonal profile of women with PCOS of early and late reproductive period is characterized by series of age-related changes in the pituitary-ovarian system, which should be taken into account in preventive and therapeutic measures.

Abstract Objective Polycystic ovary syndrome (PCOS) is a highly heritable disease. Emerging evidence elucidated the elevated prevalence of reproductive abnormalities in first-degree relatives (FDRs) of patients with PCOS. Methods Ten databases were searched in December 2020 (PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, CBM, CNKI, VIP and WanFang and WHO international clinical trials registry platform). This study included cohort, case–control, or cross-sectional studies. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement was followed. Dichotomous data from each of the eligible studies were combined by Mantel-Haenszel model. Standard mean differences with 95% confidence intervals were assessed. Heterogeneities were assessed using I  2 statistics, and the quality of evidence was evaluated by AHRQ EPC program and GRADE approach. Results Thirty-eight studies were included. The prevalence of PCOS (0.22; 95%CI 0.16 to 0.29), menstrual irregularities (0.28; 95%CI 0.22 to 0.34, P&lt;0.01) and ovary morphological changes were elevated in female PCOS FDRs. Female FDRs also presented with increased levels of luteinizing hormone, total testosterone (SMD, 0.53; 95%CI 0.28 to 0.78, P&lt;0.01), unconjugated testosterone, free androgen index, dehydroepiandrosterone sulfate (DHEAS), and anti-Mullerian hormone levels. Subgroup analyses indicated that some of these changes begun in pubertal girls. Furthermore, fathers of PCOS had higher risk of premature baldness. The DHEAS level was elevated in male FDRs. Conclusions The findings of this analysis suggested that FDRs of patients with PCOS suffered from reproductive endocrinological dysregulations. Thus, more attention should be focused on this population. (PROSPERO–CRD42020183243)
