The impact of lipid accumulation product (LAP) and visceral adiposity index (VAI) on clinical,hormonal and metabolic parameters in lean women with polycystic ovary syndrome

This study was performed to assess the impact of lipid accumulation product (LAP) and visceral adiposity index (VAI) on clinical, hormonal, and metabolic parameters in lean women with PCOS. Retrospective analysis of 120 consecutive lean PCOS subjects was performed. Subjects were divided into two groups according to HOMA-IR, as IR?+?and IR?. A HOMA-IR value above 2.5 was used to indicate IR. Clinical, hormonal and metabolic parameters were compared between the two groups. Correlations between LAP and VAI and clinical, hormonal, metabolic features in women PCOS were analyzed. One hundred twenty lean PCOS subjects were enrolled, of which 39 were insulin resistant. Comparison of group means showed significantly higher values for TG levels, FAI, FGS, TG/HDL-c, TyG, LAP, and VAI indexes and lower values for glucose/insulin ratio and QUICKI in the IR?+?group. LAP and VAI were both found to be positively correlated with each other and with WC, FAI, FGS, TG, TC levels, lipid ratios, TyG index, and HOMA-IR and negatively correlated with Glucose/Insulin ratio, QUICKI, and HDL-c in lean women with PCOS. LAP and VAI may be promising in early identification of IR and cardiometabolic risk and may be useful for the assessment of hyperandrogenism in lean women with PCOS.     

Are serum chemerin levels different between obese and non-obese polycystic ovary syndrome women?

The objective of this study is to measure serum chemerin levels in women with polycystic ovary syndrome (PCOS) and assess their relationship with clinical, metabolic, and hormonal parameters. One hundred eighteen PCOS women and 114 healthy women were recruited in this study. Their blood pressure, body mass index (BMI), waist circumference and waist-to-hip ratio (WHR), fasting insulin (FIN), fasting plasma glucose (FPG), blood serum sex hormone, and blood lipid were measured. Serum chemerin, leptin, and adiponectin were measured by ELISA. Serum chemerin was significantly higher in the obese PCOS group (47.62?±?11.27?ng/mL) compared with non-obese PCOS (37.10?±?9.55?ng/mL) and the obese (33.71?±?6.17?ng/mL) and non-obese (25.78?±?6.93?ng/mL) control groups (p?p?相似文献   

Evaluation of insulin resistance and metabolic syndrome in patients with polycystic ovary syndrome

Aim.?Polycystic ovary syndrome (PCOS) is associated with the clustering of states including insulin resistance (IR), obesity, elevated blood pressure, and dyslipidemia that are termed as metabolic syndrome (MBS). This study was designed to assess the differences between homeostatic model assessment (HOMA) values in PCOS and healthy women.

Methods.?In a case–control study, 55 women with PCOS and 59 women with normal cycles (control group) aged 15–40 years old were evaluated. In all the subjects (after obtaining written informed consent), blood pressure, body weight, height, body mass index (BMI), waist /hip ratio(WHR) and fasting blood glucose (FBG), triglycerides (TG), HDL, C-peptide, insulin, HOMA Index, and FGIR (fasting glucose to insulin ratio) were measured.

Results.?In this study, the prevalence of MBS was significantly higher in PCOS group compared with the control group (p = 0.028). There were no significant differences in age, waist/hip ratio, fasting glucose, insulin, and C-peptide levels between patients with PCOS and control group. Furthermore, the prevalence of impaired fasting glucose (IFG) and the mean of HOMA and FGIR did not differ significantly between PCOS and control group.

Conclusion.?Criteria of MBS are frequently present in young women with PCOS and may be more useful as a prognostic factor than IR indexes in this age group. We suggest evaluation of IR in older age women with PCOS.     

多囊卵巢综合征患者睡眠质量与代谢综合征的相关性分析

目的：探讨多囊卵巢综合征（polycystic ovary syndrome,PCOS）患者代谢综合征（metabolic syndrome,MS）的发病与睡眠障碍的关系,为临床防治提供指导。方法：选取2021年4—10月黑龙江中医药大学附属第一医院妇科门诊就诊的PCOS患者170例,按是否合并MS分为PCOS合并MS组（A组,40例）、PCOS无MS组（B组,130例）,另选取同期非PCOS但存在MS的患者（C组,30例）作为对照,对3组患者的临床特征、睡眠质量、睡眠状况与MS标志物的相关性进行回顾性分析。结果：A、B、C组睡眠障碍者分别为18例（45.00%）、44例（33.84%）和4例（13.33%）,各组睡眠障碍程度的差异有统计学意义（P<0.05）。A组睡眠状况评分、体质量、体质量指数、收缩压、舒张压、腰臀比、空腹血糖、空腹胰岛素、胰岛素抵抗指数、总胆固醇、三酰甘油、低密度脂蛋白胆固醇、载脂蛋白B水平均高于B组（P<0.05）;A组黄体生成素、黄体生成素与卵泡刺激素比值、性激素结合球蛋白、高密度脂蛋白胆固醇水平低于B组（P<0.05）。A组在睡眠状况评分、黄体生成素、黄体生成素与卵泡刺激素比值、睾酮、硫酸脱氢表雄酮、雄烯二酮水平均高于C组（P<0.05）;A组性激素结合球蛋白水平低于C组（P<0.05）。PCOS患者早醒、睡眠不稳与三酰甘油水平呈正相关（P<0.05）。结论：PCOS患者易合并睡眠障碍,MS与PCOS患者睡眠质量存在相互影响且MS会加重PCOS患者睡眠障碍,对于PCOS患者应重视其睡眠健康。     

The effect of hypophysectomy on inhibin production by adult rat ovaries: Changes in ovarian inhibin gene expression and serum inhibin

Our aim was to determine whether serum leptin level is regulated by thyroid hormones ,lipid metabolic products and insulin resistance status in women with polycystic ovary syndrome (PCOS). A prospective case-controlled study was carried out in Istanbul University ,Cerrahpasa School of Medicine in 25 lean PCOS (L-PCOS) women ,19 obese PCOS (O-PCOS) women and 28 normal women. The diagnosis of PCOS was established according to the clinical ,hormonal (elevated luteinizing hormone and serum androgens) and ultrasonographic findings. Fasting serum levels of thyroid stimulating hormone (TSH) ,free triiodothyronine (FT3), free thyroxine (FT4) ,fasting glucose ,insulin ,total cholesterol (TC) ,triglyceride (TG) ,high-density lipoprotein-cholesterol (HDL-C) ,low-density lipoprotein-cholesterol (LDL-C) ,very low-density lipoprotein-cholesterol (VLDL-C) and leptin were measured and compared in the three groups and the correlations between serum levels of leptin and other parameters were evaluated. Serum leptin levels were higher in the O-PCOS group ,while its level was comparable between the L-PCOS and control groups. Serum levels of FT4 were significantly lower in both L-PCOS and O-PCOS groups than the control group. Women in both L-PCOS and O-PCOS groups were found to be significantly hyperinsulinemic and insulin resistant. Serum levels of TC ,VLDL-C and TG were significantly higher in the O-PCOS group ,while serum HDL-C level was lower. There was a poor correlation between serum leptin ,and FT4 ,TC ,TG ,HDL-C and VLDL-C levels. A significant correlation was observed between serum leptin levels and both BMI and insulin resistance status in PCOS. We believe that ,although thyroid hormones and lipid metabolic products do not seem to participate in the regulation of serum leptin levels ,BMI and insulin resistance status may have a key role in women with PCOS.     

Is serum leptin level regulated by thyroid functions, lipid metabolism and insulin resistance in polycystic ovary syndrome?

Our aim was to determine whether serum leptin level is regulated by thyroid hormones, lipid metabolic products and insulin resistance status in women with polycystic ovary syndrome (PCOS). A prospective case-controlled study was carried out in Istanbul University, Cerrahpasa School of Medicine in 25 lean PCOS (L-PCOS) women, 19 obese PCOS (O-PCOS) women and 28 normal women. The diagnosis of PCOS was established according to the clinical, hormonal (elevated luteinizing hormone and serum androgens) and ultrasonographic findings. Fasting serum levels of thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), fasting glucose, insulin, total cholesterol (TC), triglyceride (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), very low-density lipoprotein-cholesterol (VLDL-C) and leptin were measured and compared in the three groups and the correlations between serum levels of leptin and other parameters were evaluated. Serum leptin levels were higher in the O-PCOS group, while its level was comparable between the L-PCOS and control groups. Serum levels of FT4 were significantly lower in both L-PCOS and O-PCOS groups than the control group. Women in both L-PCOS and O-PCOS groups were found to be significantly hyperinsulinemic and insulin resistant. Serum levels of TC, VLDL-C and TG were significantly higher in the O-PCOS group, while serum HDL-C level was lower. There was a poor correlation between serum leptin, and FT4, TC, TG, HDL-C and VLDL-C levels. A significant correlation was observed between serum leptin levels and both BMI and insulin resistance status in PCOS. We believe that, although thyroid hormones and lipid metabolic products do not seem to participate in the regulation of serum leptin levels, BMI and insulin resistance status may have a key role in women with PCOS.     

Comparison of fibrinolytic and metabolic system parameters in obese patients with polycystic ovary syndrome and women with simple obesity.

The present study aimed to assess the fibrinolytic and metabolic system parameters in obese patients with polycystic ovary syndrome (PCOS) and to compare them in obese PCOS patients and women with simple obesity. We studied 19 obese women with PCOS (age: 25.1 +/- 4.6 years, body mass index (BMI): 34.7 +/- 3.9 kg/m2; mean +/- standard deviation) and 20 age- and BMI-matched ovulatory controls. We measured blood levels of 17beta-estradiol, testosterone, prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEAS), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), glucose and insulin. The following fibrinolytic tests were also performed: euglobulin clot lysis time, plasminogen level, alpha2-antiplasmin activity, plasminogen activator inhibitor-1 activity, fibrinogen concentration and estimated fibrinolytic activity. Testosterone and LH levels were significantly higher in obese women with PCOS (p < 0.01 and p < 0.001, respectively). The groups did not differ with regard to 17beta-estradiol, prolactin, FSH, DHEAS, TC, TG, HDL-C, LDL-C, glucose and insulin. All of the fibrinolysis parameters with the exception of plasminogen were comparable between the two groups. Serum plasminogen level was lower in obese PCOS patients than in women with simple obesity (p < 0.05). Euglobulin clot lysis time was positively correlated with insulin (r = 0.88, p < 0.05) in both groups. Our results show that fibrinolysis is not suppressed in women with PCOS and that there is no difference in fibrinolytic activity between obese patients with PCOS and women with simple obesity.     

Subclinical inflammation in obese women with polycystic ovary syndrome

ObjectiveTo study the relation between subclinical inflammation and metabolic disorders in obese women with polycystic ovary syndrome (PCOS).DesignA cross sectional case controlled study.Main outcome measureAnti-inflammatory and pro-inflammatory biomarkers.Materials and methodsSixty-three obese women, body mass index (BMI) ?30 with PCOS and 45 obese women without PCOS, BMI ? 30 with normal menstrual pattern and normal morphology of the ovaries as controls. All cases were submitted to the estimation of waist circumference (WC), waist/hip ratio (WHR) and sagittal abdominal diameter (SAD) as well as fasting plasma glucose and fasting serum insulin and quantitative insulin sensitivity check index (QUICKI) to estimate the insulin sensitivity. For all subjects anti-inflammatory biomarkers acting as insulin sensitizers as interleukin (IL)-10, adiponectin, and pro-inflammatory biomarkers that depress insulin sensitivity as high sensitivity C-reactive protein (hsCRP), prothrombin activator inhibitor-1 (PAI-1), IL-6, together with, total testosterone (TT), free androgen index (FAI), sex hormone binding globulin (SHBG) together with LH and FSH as well as total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-c) and low density lipoprotein cholesterol (LDL-c) were estimated.ResultsThirty-three cases (52.38%) of PCOS and 23 cases (51.11%) of controls had android obesity and insulin resistance (IR): QUIKI < 0.330 and compensatory hyperinsulinemia (HI) and 30 cases (47.61%) of PCOS and 22 cases (48.88%) of controls had gluteofemoral (gynoid) obesity and normal insulin sensitivity (NIS). PCOS and controls with IR/HI and android obesity had significantly (P < 0.05) higher levels of pro-inflammatory biomarkers (PAI-1, IL-6 and hsCRP) and FFAs while anti-inflammatory biomarkers (IL-10 and adiponectin) were significantly (P < 0.05) lower than PCOS and controls with NIS and gynoid obesity. TT, FAI and LH were significantly (P < 0.05) higher in the two groups of PCOS than the two groups of controls. But TT and FAI were significantly (P < 0.05) higher in PCOS + IR/HI and android obesity than PCOS + NIS and gynoid obesity.ConclusionPCOS and controls with andriod obesity had higher levels of pro-inflammatory biomarkers and lower levels of anti-inflammatory biomarkers than PCOS and controls with gynoid obesity. The former groups had IR/HI and metabolic disorders of carbohydrate and lipid metabolism while the latter groups had NIS and normal metabolism. It seems that these metabolic disorders are induced by android obesity with subclinical inflammation of the expanded visceral adipose tissue rather than PCOS per se. The PCOS per se is not associated with subclinical inflammation.
