Abstract
Polycystic ovarian syndrome is an utmost communal endocrine, psychological, reproductive, and metabolic disorder that occurs in women of reproductive age with extensive range of clinical manifestations. This may even lead to long-term multiple morbidities including obesity, diabetes mellitus, insulin resistance, cardiovascular disease, infertility, cerebrovascular diseases, and ovarian and endometrial cancer. Women affliction from PCOS in midst assemblage of manifestations allied with menstrual dysfunction and androgen exorbitance, which considerably affects eminence of life. PCOS is recognized as a multifactorial disorder and systemic syndrome in first-degree family members; therefore, the etiology of PCOS syndrome has not been copiously interpreted. The disorder of PCOS comprehends numerous allied health conditions and has influenced various metabolic processes. Due to multifaceted pathophysiology engaging several pathways and proteins, single genetic diagnostic tests cannot be supportive to determine in straight way. Clarification of cellular and biochemical pathways and various genetic players underlying PCOS could upsurge our consideration of pathophysiology of this syndrome. It is requisite to know pathophysiological relationship between biomarker and their reflection towards PCOS disease. Biomarkers deliver vibrantly and potent ways to apprehend the spectrum of PCOS with applications in screening, diagnosis, characterization, and monitoring. This paper relies on the endeavor to point out many candidates as potential biomarkers based on omics technologies, thus highlighting correlation between PCOS disease with innovative technologies. Therefore, the objective of existing review is to encapsulate more findings towards cutting-edge advances in prospective use of biomarkers for PCOS disease. Discussed biomarkers may be fruitful in guiding therapies, addressing disease risk, and predicting clinical outcomes in future.

Abstract
Introduction Polycystic ovary syndrome (PCOS) may have an increased risk for the development of systemic and metabolic pathogenesis such as cardiovascular diseases, insulin resistance (IR), diabetes mellitus (DM) and dyslipidemia. However, there is no reliable marker to show the relation. Fetuin-A is an adipokine whereas paraoxonase-1 (PON-1) is a high-density lipoprotein-linked enzyme to demonstrate oxidative stress. This study aimed to evaluate serum fetuin-A and PON-1 levels in infertile PCOS women based on body mass index (BMI). Methods A prospective case-control study in a university setting was designed. A total of 88 patients admitted to the Giresun University Faculty of Medicine Gynecology Clinic between February and April 2021 were included in the study. The subjects were divided as follows: PCOS-low-BMI (BMI≤25) vs. Controls-low-BMI (BMI≤25) and PCOS-high-BMI (BMI>25) vs. Controls-high-BMI (BMI>25). Those who had at least two criteria of the 2003 Rotterdam Consensus were diagnosed with PCOS. Serum fetuin-A and PON-1 levels were compared. Results The mean levels of fetuin-A were not significantly different in the groups (p=0.955). Serum PON-1 levels were lower in the PCOS group (109.1±61.4 vs. 140.1±80.0; p=0.040), but it lost significance with adjusted values for covariants as age and BMI. Although PON-1 was not significantly different in the PCOS group of BMI<25 kg/m2 subgroup, it was significantly lower in the PCOS group of BMI≥25 kg/m2 subgroup (p=0.820 vs. p=0.048). Conclusion Serum fetuin-A activity did not differ with PCOS. Serum PON-1 might be a promising and research-worthy marker, especially for obese PCOS patients.

Abstract
Polycystic ovary syndrome (PCOS) is a considered one of the most common female disorders associated with reproductive, metabolic, and psychological problems. The etiology of PCOS is still not yet disclosed; however, evidence for a genetic basis has been reported. In this study, we investigate the associations between superoxide dismutase 2 (<i>SOD2</i>) (rs4880) and paraoxonase 1 (<i>PON1</i>) (rs705379) polymorphisms in PCOS in Saudi women. The study included 99 females with PCOS and 98 healthy women as a control. Single nucleotide polymorphisms (SNPs) of promoter regions were determined using TaqMan genotyping assays. Regarding the polymorphism at <i>SOD2</i> (rs4880), the CC, CT, and TT genotypes were present at rates of 32, 61, and 7% in PCOS patients, and 47, 43, and 10% in controls, respectively. The frequency of the CT genotype in PCOS patients (0.61) was significantly higher than in controls (0.43) (OR = 2.05, CI: 1.16–3.61; <i>p</i> = 0.015). The wild homozygous genotype (CC) with the phenotype alanine appears to confer protection against the disease compared to molecules sharing at least one valine (genotypes, CT + TT). Regarding the polymorphism at <i>PON1</i> (rs705379), the rates of CC, CT, and TT genotypes were 34, 50, and 16% in PCOS patients and 33, 63, and 2% in controls, respectively. The rate of the TT genotype in PCOS patients was significantly higher than that in controls (<i>p</i> = 0.0058). <i>SOD2</i> and <i>PON1</i> polymorphisms may be genetic factors that affect the occurrence of PCOS in Saudi females.

Abstract
Polycystic ovary syndrome (PCOS) affects several reproductive and endocrine features in females and has a poorly understood etiology. Treatment strategies for PCOS are limited and are based primarily on diet and nutrient supplementation. Recent studies have recommended some nutrients such as vitamins, minerals and vitamin-like nutrients for the therapy for PCOS. Therefore, it is claimed that the cause of PCOS could be vitamin or mineral deficiency. This review provides a narrative on the effect of nutritional supplementation on oxidative stress induced in PCOS. Oxidative stress plays a formative role in PCOS pathophysiology. This article reviews oxidative stress, its markers, nutritional supplementation and clinical studies. We also aim to show the effect of nutritional supplementation on genes affecting hormonal and glucose-mediated pathways.

Abstract
Valproate (VPA) induced changes in ovarian morphology are observed in humans with epilepsy and in non-epileptic animals. The effects of lamotrigine (LTG) on female reproduction is not well known. We investigated whether LTG might be a safer drug for use with patients of reproductive age. Forty Wistar albino female rats were divided into five groups. The control group was injected with saline-vehicle solution. The low dose (LD)-VPA group was injected with 100 mg/kg VPA. The high dose (HD)-VPA group was injected with 500 mg/kg VPA. The LD-LTG group was injected with 10 mg/kg LTG. The HD-LTG group was injected with 50 mg/kg LTG. We evaluated histological and biochemical changes in the ovaries. The number of atretic and cystic follicles was increased in the HD-VPA and HD-LTG groups compared to the control group. A significant increase in malondialdehyde level was found in the VPA groups compared to the control and LTG groups. No significant differences in total glutathione levels or superoxide dismutase activity were found among study groups. Catalase activity was significantly higher in HD-VPA and HD-LTG groups compared to the control, LD-VPA and LD-LTG groups. Prevalence and intensity of caspase-3 immunoreactivity in the luteal cells were significantly greater in the HD-LTG group compared to the control group. VPA administration caused polycystic ovarian syndrome-like changes in the ovary. We found that LD-LTG, which reflects the dose for humans, might be a safer option for use during the reproductive age.

Abstract
PURPOSE To investigate the proportion and clinical characteristics of obstructive sleep apnea (OSA) in Chinese patients with polycystic ovarian syndrome (PCOS) through home sleep apnea test (HSAT) and to evaluate the reproductive endocrine and metabolic characteristics in these patients. METHODS The study was a cross-sectional analysis of infertile PCOS patients who underwent sleep respiratory monitoring between January and December 2019 at Peking University Third Hospital Reproductive Medical Center and respiratory and critical care medicine department. The prevalence of OSA, body mass index (BMI), menstruation, reproductive endocrine, and metabolic characteristics were collected in patients with PCOS. Logistic regression was performed to identify significant relationships among these factors and OSA. RESULTS Amont 328 patients with PCOS, the prevalence of OSA was 40% (131/328), and six cases (5%) were severe. Univariate analysis showed that BMI and blood pressure were significantly higher in patients with OSA than in those without OSA (P < 0.05), whereas the anti-Mullerian hormone was lower than that in patients without OSA. In terms of glucose and lipid metabolism, the glycosylated hemoglobin (HbA1c), fasting plasma glucose, and fasting insulin levels were significantly higher in patients with PCOS and comorbid OSA than in those without OSA (all P < 0.05). Patients with OSA also had higher triglyceride, low-density lipoprotein cholesterol, and high-sensitivity C-reactive protein levels and lower high-density lipoprotein cholesterol levels (P < 0.05). Logistic regression analysis revealed that higher BMI, elevated serum testosterone, and decreased high-density lipoprotein cholesterol (HDL-C) are correlated with occurrence of OSA (P < 0.05). CONCLUSION OSA in patients with PCOS was associated with multiple alterations in indexes of reproductive endocrine and metabolic disorders.

Abstract
This study aimed to evaluate the concentration of proprotein convertase subtilisin/kexin type-9 (PCSK9) and the activities of paraoxonase 1 in women with and without polycystic ovary syndrome (PCOS). We found significant higher PCSK9, whereas lower high-density lipoprotein concentration in the serum of women with PCOS when compared to the group without PCOS. Also paraoxonase 1 activities were significantly different between women with PCOS than without PCOS. In addition, the women with PCOS and insulin resistance had higher concentrations of PCSK9 than women with PCOS and insulin sensitivity. Higher PCSK9 concentration in the group with PCOS could be also associated with hormones concentrations. Changes in paraoxonase 1 activities and lipid profile parameters as well as higher concentration of PCSK9 in the group of women with PCOS could be associated with metabolism disorders, but due to the small clinical sample size, the study should be continued.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders, occurring in 5–10% women in reproductive ages. Despite a long history of studies on PCOS, its etiology is still unknown. Oxidative stress is now recognized to play a central role in the pathophysiology of many different disorders, including PCOS. Although intracellular reactive oxygen species (ROS) production and propagation are controlled by highly complex antioxidant enzymatic and non-enzymatic systems, understanding of mechanisms that oxidative stress is important to develop strategies for prevention and therapy of PCOS. This article reviews the literature data related to the mechanisms of oxidative stress in PCOS.

Abstract
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.

Abstract
Polycystic ovarian syndrome is one of the most common hormonally leading cause infertility disorders. The effect of oxidant-antioxidant imbalance on disease progression has been studied in many disorders. The present study was aimed to evaluate prooxidant-antioxidant balance (PAB) in patients with polycystic ovarian syndrome compared to healthy subjects. We also studied the possible effect of treatment with available drugs on serum PAB. In this case-control study 100 polycystic ovary syndrome (PCOS) patients and 100 healthy individuals were enrolled in the study. The laboratory features of patients and controls like as serum LH and FSH concentration and hematological examinations were collected. PAB was evaluated by a colorimetric method. Serum PAB value was significantly higher before treatment compared to after treatment and healthy subjects. PAB values were also higher in subjects with irregular menstrual cycle compared to normal subjects. Our results represented that serum PAB values has an indirect significant correlation with serum LH concentration. We also found that drugs regimen containing spironolactone effectively reduced the serum PAB values. Our results showed that PCOS patients had increased level of PAB and treatment with spironolactone mainly decreases the level of serum PAB. Our results indicate that the measurements of PAB may be used as a potential laboratory marker for assessment of PCOS patients.

Differential effects of a high-fat diet on serum lipid parameters and ovarian gene expression in young and aged female mice. ZYGOTE 2016; 24:676-83. [PMID: 26883034 DOI: 10.1017/s0967199415000684] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/29/2022]
Abstract
The aim of this study was to compare serum lipid profiles and ovarian gene expression between aged and younger female mice fed a control or a high-fat diet for 2 months. For this 16 female mice (C57BL/6) of 4 months (Young, n = 8) or 13 months (Old, n = 8) of age were used. The females were divided into four groups: (i) young females fed a normal diet; (ii) young females fed a high-fat diet; (iii) old females fed a normal diet; and (iv) old females fed a high-fat diet. Food intake was reduced (P < 0.05) in mice fed with a high-fat (2.9 ± 0.1 g) diet in comparison with control mice (3.9 ± 0.1 g). Body weight was higher for old females on the high-fat diet (35.1 ± 0.3 g) than for young females on the same diet (23.3 ± 0.4 g; P < 0.05). PON1 activity was lower in the high-fat than control diet group (114.3 ± 5.8 vs. 78.1 ± 6.0 kU/L, respectively) and was higher in older than younger females (85.9 ± 6.4 vs. 106.5 ± 5.3; P < 0.05, respectively). Females fed a high-fat diet had lower expression of Igf1 mRNA (P = 0.04). There was an interaction between age and diet for the expression of Gdf9 and Survivin, with lower expression in older females in both diets and young females that received the high-fat diet (P < 0.05). Concluding, the high-fat diet reduced the expression of ovarian Igf1 mRNA, and Gdf9 and Survivin mRNA in younger females, which can indicate lower fertility rates. High-density lipoprotein concentration and PON1 activity were higher in aged female mice.

Abstract
The exact etiology and pathogenesis of eczema are not yet fully understood, although different factors are considered as pathogenic mechanisms in the development of eczema. Our study was designed to determine extent of serum lipid peroxidation, antioxidants, macro minerals and trace elements in patients with eczema, and thereby, find any pathophysiological correlation. The study was conducted as a case-control study with 65 eczema patients as cases and 65 normal healthy individuals as controls. Lipid peroxidation was assessed by measuring the serum level of malondialdehyde (MDA). Antioxidants- vitamin A and E concentration was determined by RP-HPLC method whereas vitamin C was evaluated for serum ascorbic acid by UV spectrophotometric method. Serum macro minerals (Na, K, Ca) and trace elements (Zn, Fe) were determined by Atomic Absorption Spectroscopy (AAS). This study found significantly higher level of MDA (p < 0.001) and lower level of antioxidants (p < 0.05) in patients in comparison to the control subjects. Analysis of serum macro minerals (Na, K and Ca) and trace elements (Zn, Fe) found that the mean values of Na, K, Ca, Zn and Fe were 2771.60 ± 75.64, 66.33 ± 3.03, 48.41 ± 2.50, 0.30 ± 0.02 and 0.29 ± 0.009 mg/L for the patient group and 3284.81 ± 34.51, 162.18 ± 3.72, 87.66 ± 2.10, 0.75 ± 0.06 and 0.87 ± 0.06 mg/L for the control group, accordingly. There was a significant difference for all the minerals between the patients and controls (p < 0.001). This study suggests a strong association between the pathogenesis of eczema with the elevated level of MDA and depleted level of antioxidants, macro minerals, and trace elements.

Abstract
OBJECTIVE To investigate the association of paraoxonase 1 (PON1) polymorphisms (L55M and Q192R) with polycystic ovary syndrome (PCOS) susceptibility and its related traits in Indian women. DESIGN Case-control study. SETTING Academic research institute, infertility, and endocrinology clinics. PATIENT(S) Controls (n = 326), women with PCOS (n = 482). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Genotypic and allelic frequency distribution, genotype-phenotype association, different PON1 activities (lactonase, arylesterase, and paraoxonase). RESULT(S) The genotypic and allelic frequency distributions of the L55M polymorphism were significantly different between lean controls and lean women with PCOS, and this polymorphism reduced the risk of PCOS development in lean but not in obese Indian women. Furthermore, this polymorphism was significantly associated with decreased 2-hour glucose, apolipoprotein B, free and bioavailable T, and free androgen index concurrent with increased sex hormone-binding globulin (SHBG) and FSH levels only in lean women with PCOS. However, Q192R polymorphism showed comparable genotypic frequency distribution between controls and women with PCOS. PON1 lactonase and arylesterase activities were significantly decreased in women with PCOS compared with controls. PON1 polymorphisms were shown to influence its activities. CONCLUSION(S) Our study showed that L55M, but not Q192R, polymorphism is significantly associated with reduced PCOS susceptibility only in lean women and also impacts glucose metabolism, lipid parameters, and hyperandrogenemia in them. Our study therefore suggests the possibility of differential genetic pathophysiology of PCOS between lean and obese women.

Abstract
OBJECTIVE To study the relationship between the lactonase activities and status of paraoxonase 1 (PON1) and its association with the PON1 genetic polymorphisms in women with polycystic ovarian syndrome (PCOS). DESIGN A case-control study. METHODS A total of 455 PCOS patients and 441 control women were included in this study. The lactonase activities and concentrations of PON1 were assayed using 5-thiobutyl butyrolactone (TBBL) and 7-O-diethylphosphoryl-3-cyano-4-methyl-7-hydroxycoumarin (DEPCyMC) respectively. A normalized lactonase activity (NLA) was estimated based on the ratio of TBBLase:DEPCyMCase activity. The PON1 genotypes, serum malondialdehyde (MDA) levels and total antioxidant capacity were analyzed. RESULTS The lactonase activities and levels of PON1 were higher in PCOS patients than in the control women. However, the NLA did not significantly differ between groups. The -108C→T variation of the PON1 gene showed decreased lactonase activities and levels of PON1 in a genotype-dependent manner (CC>CT>TT); the 192Q→R variation of the PON1 gene showed increased PON1 lactonase activities and NLA; and the 55L→M variation of the PON1 gene showed decreased lactonase activities and levels of PON1 but an increased NLA. A multivariable regression analysis showed that the -108C/T, 192Q/R, and 55L/M variations of the PON1 gene, serum apolipoprotein A1, and MDA levels were significant predictors of PON1 lactonase activity, PON1 level, and NLA. CONCLUSIONS The serum lactonase activities and concentrations of PON1 are increased in PCOS patients. The increased oxidative stress and the -108C/T, 192Q/R, and 55L/M genetic polymorphisms of PON1 may be associated with these changes.

Abstract
OBJECTIVE To investigate the serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), and Paraoxonase-1 (PON-1) during fertility treatment of women with endometriosis (Endo), PCOS or unexplained infertility (Unexpl). METHODS Thirty-six patients with Endo, PCOS or Unexpl undergoing controlled ovarian stimulation for IVF or IUI were consented and their serum, on day-3 (baseline) and at the end of FSH treatment (peak), was collected and investigated for levels of TNF-α, IL-6, MCP-1, and PON-1. Correlations, ANOVA and Student's t-test were used for statistical analysis. RESULTS Peak serum levels of IL-6, MCP-1 and PON-1 were positively correlated to E2 peak levels. TNF-α levels were inversely correlated to estradiol levels and they were lower in patients who ultimately became pregnant when compared to non-pregnant (P < 0.05). Mean TNF-α levels were significantly higher in Unexpl group (P < 0.05). The mean levels of IL-6, and MCP-1 were significantly (p < 0.05) higher in women with PCOS compared with Endo and Unexpl. No differences were found between the three clinical groups in patient's age, BMI, Day-3 FSH, PON-1 and pregnancy outcome. CONCLUSION Circulating cytokine levels were influenced by ovarian stimulation, as demonstrated by increased levels of IL-6, MCP-1 and PON-1, and decreased level of TNF-α at the end of controlled ovarian stimulation. While evidence of relationship between circulating cytokines with mild endometriosis was not found, PCOS was associated with elevated serum IL-6 and MCP-1 but lower TNF-α concentration. Unexplained infertility was associated with elevated TNF-α level. No relationship between serum PON-1 concentration and PCOS, mild endometriosis or unexplained infertility was noted.

Abstract
Polycystic ovary syndrome (PCOS) is a heterogeneous disorder, which is considered not only a reproductive disease but also a metabolic disorder associated with long-term health risks. The aim of this study was to assess the effects of metformin on insulin resistance, oxidant-antioxidant status, endothelial dysfunction, lipid metabolism and their contribution to the risks of cardiovascular disease in women with PCOS. Fifteen women with PCOS and 17 healthy women were included in this case-control study. Nitric oxide (NO), endothelin-1 (ET-1), malondialdehyde (MDA), Apo A1, Apo B, small, dense LDL cholesterol (sdLDL-C), lipid levels and paraoxonase 1 (PON1) activity were measured in serum/plasma obtained from study groups. Insulin resistance (HOMA index - Homeostasis Model Assessment) and serum sex hormone profiles were also evaluated. Significantly decreased NO levels and PON1 activities, but increased MDA, ET-1 and sdLDL-C were found in PCOS patients compared to those of controls. Serum MDA, ET-1, HOMA and sdLDL-C levels decreased and PON1 activity and NO levels increased significantly after the metformin treatment. There was a positive correlation between MDA and free testosterone (fT), ET-1 and fT; and a negative correlation between PON1 activity and fT. Insulin resistance, dyslipidemia, endothelial dysfunction and oxidative stress might contribute to the excess risk of cardiovascular disease reported in PCOS. Metformin seemed to decrease oxidative stress and improve insulin resistance, dyslipidemia and endothelial dysfunction in PCOS patients.

Abstract
Polycystic ovary syndrome (PCOS) is possibly the most common endocrine disorder in premenopausal women. In this study, we aimed to investigate the association of the -108 C>T polymorphism in the PON1 gene, which encodes the antioxidant enzyme paraoxonase-1, with PCOS. A total of 118 women with PCOS and 108 control subjects were included in this case-control study. The PON1 polymorphism was genotyped, biochemical and clinical parameters were determined and the correlations between the parameters were statistically evaluated. The differences in the PON1 allele and genotype distributions between PCOS patients and controls did not reach a statistical significance. The serum fasting glucose (GLU) levels did not differ significantly between the PCOS patients and the controls. However, the serum fasting insulin (INS) concentration, INS/GLU ratio and homeostasis model assessment (HOMA) index, although within the normal range, were significantly higher in the PCOS group. When considering PCOS patients and controls as separate groups or as a single group of patients, none of the analyzed biochemical or clinical parameters were found to be significantly correlated with the PON1 polymorphism. Therefore, the -108 C>T PON1 polymorphism was not found to be significantly associated with the presence of PCOS or with its particular clinical and biochemical characteristics in non-insulin resistant, non-obese patients.

Abstract
OBJECTIVE To investigate the frequencies of three paraoxonase (PON)1 polymorphisms in Greek polycystic ovary syndrome (PCOS) and non-PCOS women, and their genotypes association with hyperandrogenaemia and insulin resistance. DESIGN Case-control genetic association study. SETTING University Hospital Endocrine Unit. PATIENTS A total of 142 PCOS cases (NIH criteria) and 112 controls. MAIN OUTCOME MEASURE Genotyping of the c.-108C>T (PON1-108), the c.163T>A (PON1-55) and the c.575A>G (PON1-192) polymorphisms and measurement of baseline androgen and insulin resistance profile. RESULTS The PON1-108 TT and PON1-192 RR genotypes were more frequently encountered in the PCOS than in the control group. The PON1-192 R allele frequency was greater in the PCOS than in the control group. Comparing the PCOS and the control groups, statistical significances favoured a recessive and a dominant genetic model, respectively, for the single PON1-108 T and PON1-192 R alleles. Free Androgen Index (FAI) levels were higher in patients with PON1-108 TT, whereas Testosterone, FAI and Dehydroepiandrosterone sulphate (DHEAS) levels were higher in patients with PON1-192 RR than patients with the wild or the heterozygous genotype. CONCLUSIONS The decreased PON1 activity-associated PON1-108 TT and the PON1-192 RR genotypes are more frequently found in Greek PCOS women and are associated with hyperandrogenaemia. Hyperandrogenaemia must depend also on other genetic factors because the same genotypes were not associated with hyperandrogenaemia in the control group. Through identification of the involved polymorphisms, women with PCOS could potentially have a better therapeutic screening.

Abstract
Human serum paraoxonase 1 (PON1) is an enzyme with esterase activity, and is physically bound to high-density lipoproteins (HDL). It plays a key role in the action of HDL toward protection of lipoprotein and biological membrane against oxidative damage. It may have a protective role against atherosclerosis by virtue of its action on hydrolyzing lipid peroxides and preventing accumulation of phospholipids in oxidized low-density lipoprotein (LDL). PON1 is hypothesized to be an indicator of the risk of atherosclerosis and coronary artery disease development. Numerous studies have implicated PON1 activity in relation to various endocrine disorders. The current article reviews the clinical perspectives of PON1 activity with regards to obesity, diabetes mellitus with its complications, and dyslipidemia.

Abstract
BACKGROUND Oxidative stress might be associated with polycystic ovary syndrome (PCOS), but relatively small studies published to date do not permit reaching a definitive conclusion. We aimed at conducting a systematic review and meta-analysis of studies evaluating circulating markers of oxidative stress in patients with PCOS. METHODS We conducted a systematic review of studies reporting circulating markers of oxidative stress in women with PCOS and controls published up to June 2012, using Entrez PubMed and EMBASE online facilities. Meta-analysis calculated standardized mean differences (SMDs) and 95% confidence intervals (95CI). RESULTS From 1633 potential studies identified electronically, 68 studies, including 4933 PCOS patients and 3671 controls, were selected. For each of nine circulating markers of oxidative stress, an individual meta-analysis was conducted. Compared with control women, patients with PCOS presented higher circulating concentrations of homocysteine (23% increase, SMD 0.6, 95CI, 0.4-0.8), malondialdehyde (47% increase, SMD 1.9, 95CI 1.2-2.6) and asymmetric dimethylarginine (36% increase, SMD 1.1, 95CI 0.6-1.6), and increased superoxide dismutase activity (34% increase, SMD 1.0, 95CI 0.5-1.4) and decreased glutathione levels (50% decrease, SMD -3.7, 95CI -6.2 to -1.2) and paraoxonase-1 activity (32% decrease, SMD -0.9, 95CI -1.3 to -0.4). Similar results were found when restricting the analyses to studies in which patients and controls were matched for age and body mass index. CONCLUSIONS Circulating markers of oxidative stress are abnormal in women with PCOS independent of weight excess. This finding suggests that oxidative stress may participate in the pathophysiology of this common disorder.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with increased risk of cardiovascular disease. The purpose of this study was to investigate the ef¬fects of omega-3 fatty acids on serum paraoxonase 1 activity and lipids ratios in polycystic ovary syndrome. METHODS This double-blind randomized controlled clinical trial was conducted on 64 PCOS pa¬tients with 20-35 years old. Thirty two of the subjects had taken 4 g/day omega -3 fatty acids and 32 patients were given placebo for 8 weeks. Fasting blood samples, anthropometric measure¬ments and dietary intakes were collected at the beginning and the end of the study. Serum total cholesterol, triglyceride, and HDL-C were measured using the enzymatic methods. LDL-C con¬centration was calculated by the Friedewald formula and arylesterase activity of serum PON1 was measured. Data were analyzed using SPSS software. RESULTS Omega-3 fatty acids significantly decreased TC/HDL-C and LDL-C/HDL-C ratios (P = 0.009 for both) and significantly increased serum PON1 activity (P = 0.048) compared with placebo. Changes in TG/HDL-C ratio were not statistically significant in omega-3 fatty acids group at the end of the study in comparison to placebo group. Reduction in TC/HDL-C, LDL-C/HDL-C and TG/HDL-C ratios and increase in serum PON1 activity were also significant in omega-3 fatty acids group at the end of the study compared with baseline values (P <0.001, P < 0.001, P = 0.004, and P = 0.001, respectively). CONCLUSION Omega-3 fatty acids may decrease the risk for cardiovascular disease through the improvement in paraxonase-1 activity and reduction in some lipids ratio in PCOS women.

Abstract
OBJECTIVE Paraoxonase1 (PON1), exhibits both esterase activity (PON1-AREase) and homocysteine thiolactonase activity (PON1-HTLase) which respectively prevent LDL oxidation and detoxify homocysteine thiolactone (HTL). Platelet-activating factor-acetylhydrolase (PAF-AH) is an antioxidant enzyme preventing LDL oxidation by hydrolysis of oxidized phospholipids. Both of these enzymes exhibit a proatherogenic role. ADMA is an endogenous inhibitor of nitric oxide (NO) synthesis causing endothelial dysfunction. The aim was to compare non-obese PCOS patients with a BMI matched control group using the following characteristics: serum PON1-HTLase, ADMA, PAF-AH, and lipid and hormonal parameters. RESULTS 77 women with PCOS and 25 healthy subject were recruited for this study, The controls were non-obese BMI and age matched with the patients. There were no significant differences with respect to age, BMI, FSH, free testosterone, DHEA, androstenadion, total cholesterol, triglycerides, HDL, LDL, VLDL, fasting glucose/insulin ratio and HOMA-IR among the groups (p > 0.05). However, total testosterone and fasting glucose levels were significantly higher in the PCOS group (p < 0.05). On the other hand, PON1-HTLase levels (39.6 ± 5.77 vs. 33.8 ± 8.2, p = 0.02) were significantly lower in the PCOS group while ADMA levels (1.14 ± 0.6 vs. 3.37 ± 6.4, p = 0.004) were significantly higher in the PCOS group. However, there was no significant difference in PAF-AH activity among the groups. CONCLUSIONS Decreased PON1-HTLase and increased ADMA levels might be a relevant marker for the development of future atherosclerotic heart disease (AHD) in non-obese PCOS patients. Further studies are needed to confirm our results.

Abstract
The aim of this study was to assess relationship of insulin resistance, oxidant-antioxidant status, endothelial dysfunction, lipid metabolism, and their contribution to the risks of cardiovascular disease in women with polycystic ovary syndrome (PCOS). Forty-five women with PCOS and 17 healthy women were included in this study. Nitric oxide (NO), endothelin-1 (ET-1), malondialdehyde (MDA), Apo A1, Apo B, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), triglyceride, small, dense LDL cholesterol (sdLDL-C), large buoyant LDL cholesterol (LbLDL-C) levels, and paraoxonase 1 (PON1) activity were measured in serum/plasma obtained from study groups. Insulin resistance [homeostasis model assessment (HOMA) index] and serum sex hormone binding globulin (SHBG), total testosterone (tT), free testosterone (fT), androstenedione, and dehydroepiandrosteronsulfate (DHEAS) levels were also evaluated. Significantly decreased SHBG, NO, HDL-C levels, and PON1 activities, but increased tT, fT, androstenedione, DHEAS, HOMA index, MDA, ET-1, LDL-C, sdLDL-C, and LbLDL-C values were found in PCOS patients compared with those of controls. There was a positive correlation between MDA and fT levels; and a negative correlation between PON1 activity and fT. Our data show that insulin resistance, dyslipidemia, endothelial dysfunction, and oxidative stress might contribute to the excess risk of cardiovascular disease reported in PCOS patients.

Abstract
OBJECTIVE The aim of this study was to investigate the relationship between 192Q/R and 55L/M polymorphisms of paraoxonase 1 (PON1) gene and polycystic ovarian syndrome (PCOS) in Chinese women. DESIGN A case-control study. METHODS A total of 1113 subjects (610 patients with PCOS and 503 control women) from a population of Chinese Han nationality in Chengdu area were included in this study. PON1 genotypes were studied using PCR and restriction fragment length polymorphism analysis. Clinical and metabolic parameters were analyzed. RESULTS The frequencies of PON1 192RR genotype and R allele were significantly higher in patients with PCOS than in control women (44.6 vs 36.4%, 0.667 vs 0.610 respectively). The 192RR genotype remained a significant predictor for PCOS (odds ratio (RR/QR)(+)(QQ): 1.656, 95% confidence interval: 1.156-2.371) in prognostic models including age, body mass index, insulin resistance index, triglyceride, HDL, and LDL as covariates. Compared with patients with QQ genotype, patients with RR or QR genotype had significantly higher waist circumference and fasting insulin and triglyceride levels, patients with RR genotype had significantly higher waist-to-hip ratio, and patients with QR genotype had significantly higher homeostasis model assessment of insulin resistance. Such relationships were not detected in the control women. No significant differences were found in the frequencies of PON1 55L/M genotype and allele between PCOS and control groups. CONCLUSIONS The 192Q/R, but not 55L/M, polymorphism in PON1 gene is associated with the risk of PCOS in south-west Chinese women.

Abstract
BACKGROUND Oxidative stress may play a role in the pathophysiology of polycystic ovary syndrome (PCOS). Insulin resistance (IR) also can be found in young non-obese women with PCOS. Hyperglycemia may increase reactive oxygen species production and decrease antioxidant levels. AIM To investigate oxidative status and its relation with IR in young non-obese patients with PCOS. MATERIAL/SUBJECTS AND METHODS Thirty-one patients with hyperinsulinemic (no.=13) and normoinsulinemic (no.=18) PCOS and 29 healthy controls were included in this study. Serum levels of glucose, insulin, gonadotropins, total testosterone, DHEAS, SHBG, 2-h plasma glucose on oral glucose tolerance test, malondialdehyde (MDA), protein carbonyl (PC), reduced glutathione (GSH), β carotene, vitamin A, C, E and the enzyme activities of catalase and glutathione S-transferase (GST), IR [by homeostasis model assessment (HOMA)-IR], and β cell function [by HOMA-B] were assessed. RESULTS Serum glucose, insulin, total testosterone, DHEAS, HOMA-IR levels, and LH/FSH ratios were higher in young non-obese women with PCOS. Serum MDA and PC levels were also higher but GSH, vitamin C and E levels, and GST enzyme activity were lower in these women than in healthy controls, independently of the status of IR (p<0.05). CONCLUSIONS Oxidative stress characterized by increased oxidants and decreased antioxidant levels which are independent of IR may be involved in the pathogenesis of PCOS in young non-obese women.

Abstract
Paraoxonase-1 (PON1) activity is decreased in polycystic ovary syndrome (PCOS) having metabolic syndrome (MetS) or insulin resistance (IR). We aimed to assess PON1 activity and oxidative stress in PCOS without MetS or IR. Metabolic and hormonal parameters, high-sensitive C-reactive protein (hs-CRP), oxidative stress parameters (total antioxidant status (TAS), total oxidative stress (TOS), oxidative stress index (OSI), lipid hydroperoxide (LOOH), total free sulfhydryl (--SH) groups), PON and arylesterase were analyzed in 30 normal weighed patients with PCOS without MetS or IR and 20 normal controls. Hs-CRP, PON, arylesterase, and TAS levels of PCOS and control groups were similar. LOOH, TOS, and OSI of PCOS group were higher than in the controls (p < 0.05; p < 0.001, and p < 0.001, respectively). - SH group levels showed a positive correlation with free testosterone (fT). TOS positively correlated with free androgen index (FAI), body mass index (BMI), waist-to-hip ratio (WHR), LOOH, and OSI. This study showed that oxidative stress is increased in PCOS even in the absence of MetS or IR. PON1 activity appears not to be affected in PCOS without MetS and IR. Several metabolic and antropometric risk factors may aggravate this altered oxidative state in PCOS.

Abstract
AIM The consequences of bariatric surgery on important metabolic and signaling pathways are still poorly understood. The aim of our study was to unravel the network of metabolic changes and obesity-related protein biomarkers in morbidly obese children and adolescents undergoing laparoscopic sleeve gastrectomy (LSG). METHODS In a prospective study, 6 children with morbid obesity who had failed a well-established conservative weight loss therapy underwent LSG. Pre- and 6 months postoperatively, a metabonomic profiling of 163 metabolites by mass spectrometry and protein profiling by ELISA (clusterin [CLU], pigment epithelium-derived factor [PEDF], retinol binding protein 4 [RBP4], paraoxonase 1 [PON1]) was performed to identify biomarkers of important pathways. RESULTS At referral for surgery, the mean age was 14.5 years (range 8-17), mean body mass index (BMI in kg/m(2)) was 48.13 (range 41.1-56.3). All patients showed various metabolic comorbidities. LSG was uneventful in all of them. At 6 months postsurgery, the mean BMI has dropped to 37.1 (range 28.4-40.6). Targeted serum metabonomics resulted in 7 metabolites, which were significantly affected by LSG. Among those, the amino acid phenylalanine was increased, and methionine decreased. The glycero-phospatidylcholine PCaaC38:5 were upregulated, and PCaaC40:2 and PCaaC42:1 were down regulated after 6 months compared with baseline. Further, sphingomyoline (SM) C26:0 and SM C26:1 were decreased after 6 months. The obesity-related biomarkers CLU, PEDF, and RBP4 were decreased, whereas PON1 levels were increased. CONCLUSION LSG leads to changes in amino acids and in lipid metabolism indicated by glycerol-phosphatidylcholines and SM. The pattern of protein biomarkers and metabolites might provide measures for the induced physiological changes and for therapy monitoring.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is an endocrine disorder with a complex pathogenesis in which hormonal disturbances, metabolic disorders and chronic inflammation have been considered. Relationships among the paraoxonase 1 (PON1) gene, hyperandrogenism and insulin resistance in women with PCOS have been reported. AIM The aim of this study was to evaluate patients with PCOS for the existence of chronic inflammation and to assess the relationship between PON1 polymorphism and hormonal, metabolic and inflammatory parameters in these women. MATERIAL AND METHODS One hundred thirty women with PCOS and 70 healthy women were studied. Anthropometric, hormonal (total testosterone, androstenedione, DHEA-S, LH, FSH), metabolic (fasting glucose and insulin, oral glucose tolerance test, insulin sensitivity and resistance indices, lipids) and inflammatory parameters (hsCRP, fibrinogen, WBC) were assessed and analysis of PON1 Leu55Met polymorphism was carried out in all subjects. RESULTS WBC, fibrinogen and hsCRP levels did not differ significantly between the PCOS and control groups. The genotype frequencies of the Leu55Met PON1 polymorphism were similar in both groups. There were no relationships between PON1 genotypes and metabolic parameters. CONCLUSIONS As chronic low-grade inflammation was not observed in the women with PCOS, there is no direct link between inflammation and PCOS markers per se. None of the variants of the Leu55Met PON1 polymorphism was associated with more frequent occurrence of PCOS or metabolic disorders, including insulin resistance.

Abstract
In this observational, case-control study in infertile women, we observed elevated serum oxidative stress that was significantly correlated with an increase in serum paraoxonase-1 activity and without any evidence of a proinflammatory reaction. These results suggest a protective role of paraoxonase-1 against inflammation in this clinical setting.

Abstract
BACKGROUND Paraoxonase enzyme was first identified as a protective barrier against organophosphorus poisoning. After painstaking research spanning the last three decades, the knowledge about this enzyme has increased immensely. The present review attempts to elaborate the role of paraoxonase enzyme in normal physiology as well as provide an overview of the various disorders in which the enzyme may have a role in etiopathogenesis. METHODS The literature was searched from the websites of the National Library of Medicine (http://www.ncbi.nlm.nih.gov/) and Pub Med Central, the U.S. National Library of Medicine's digital archive of life sciences journal literature. RESULTS Paraoxonase acts as an important antioxidant enzyme against oxidative stress. The enzyme has been implicated in the pathogenesis of a number of disorders including cardiovascular disorders, cancers etc. CONCLUSIONS A better understanding of the molecular mechanism of the enzyme along with the regulatory circuits will help us to utilize agonists to potentiate the anti oxidant actions of the enzyme.

Abstract
Polycystic ovary syndrome (PCOS) is associated with a clustering of metabolic and cardiovascular risk factors. Insulin resistance is implicated as the major player in the metabolic abnormalities and contributes to the increased cardiovascular risk associated with the syndrome. However, androgen excess appears to participate as an independent parameter, which further aggravates the cardiovascular and metabolic aberrations in affected women with PCOS. The resultant impact of hyperandrogenemia possibly acquires clinical significance for women's health in the context of PCOS, particularly since recent data support an increased incidence of coronary artery disease and of cardiovascular events directly related to androgen levels in women with the syndrome.

Abstract
BACKGROUND Because serum paraoxonase activity is influenced by the -108C/T polymorphism in the PON1 gene, we studied its involvement in the decreased paraoxonase activity recently described in the polycystic ovary syndrome (PCOS). METHODS Paraoxonase activity, PON1-108C/T genotypes and clinical, hormonal and biochemical variables were evaluated in a case-control study involving 139 consecutive PCOS patients and 85 healthy controls matched for BMI and prevalence of smoking. RESULTS Women homozygous for -108T presented with reduced serum paraoxonase activity compared with carriers of C alleles (P < 0.001), both in PCOS patients and in controls. Although homozygosity for T alleles was more prevalent in PCOS patients than in controls (P = 0.003), serum paraoxonase activity was not significantly different in the PCOS and control groups. In a stepwise multivariate linear regression model, homozygosity for PON1-108T alleles was the only significant predictor of the logarithm of serum paraoxonase activity (beta = -0.328, t = -4.176, P < 0.001). CONCLUSIONS In premenopausal women from the Spanish population, the PON1-108C/T polymorphism, and not PCOS, is an important determinant of serum paraoxonase activity.
