Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder. Atrial natriuretic peptide (ANP) is a risk factor for PCOS. Corin protein has an essential role in ANP synthesis. This study aimed to evaluate corin as a sensitive biomarker for PCOS. MATERIALS AND METHODS A case-control study was conducted with 70 PCOS patients and 70 healthy females. Plasma Corin levels were quantified using enzyme-linked immunosorbent assay. RESULTS The median plasma corin levels in PCOS patients and controls were 1785 and 822.5 pg/mL, respectively. Plasma corin levels were significantly elevated in PCOS patients than in the controls (p < 0.001). The optimal cut-off value was set at 1186 pg/mL. The sensitivity and specificity of Corin were 100% and 97.1%, respectively. Plasma corin levels were surrogate predictors for infertility in women with PCOS. It had an odds ratio of 5.9 (95% confidence interval: 1.1-32.7) (p = 0.04). Plasma corin levels were more highly detected in patients with PCOS than in the controls. CONCLUSION Plasma corin level has reasonable diagnostic interpretation for PCOS. Corin appears as a worthy distinct predictor of infertility in PCOS women. Therefore, Corin may be a substantial biomarker for PCOS.

Abstract
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR) has been suggested to be a potential biomarker for assessing the systemic inflammatory response in polycystic ovary syndrome (PCOS). This meta-analysis is aimed at evaluating whether PCOS patients present with a higher NLR and whether obesity, metabolic, and hormonal indices have effects on the states. METHODS We performed a literature search on PubMed, Embase and Web of Science (last update: August 2, 2022). Pooled standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated by applying random-effects models. Meta-regression analyses were used to explore the sources of heterogeneity and assess the relationship between NLR and several clinical parameters. Sensitivity analysis and publication bias were also assessed. RESULTS Thirteen studies involving 826 PCOS patients and 780 healthy controls were eligible for the present meta-analysis. Generally, NLR significantly increased in PCOS women versus healthy women (SMD = 0.81, 95% CI = 0.30-1.33, P = .002). NLR disparity was subsequently investigated in obese and non-obese cohorts. Obese PCOS women exhibited a higher NLR than obese controls (SMD = 0.56, 95% CI = 0.24-0.87, P = .001), and a similar difference was shown between non-obese PCOS and non-obese controls (SMD = 0.36, 95% CI = 0.02-0.71, P = .038). No significant NLR disparity was observed between obese versus non-obese PCOS women (SMD = 0.50, 95% CI = -0.37 to 1.38, P = .259). Meta-regression analysis revealed that NLR was significantly positively associated with fasting blood glucose (P = .006) and total cholesterol levels (P = .021), but not correlated with body mass index and other parameters in PCOS patients. Sensitivity analysis indicated that no individual study significantly affected the overall pooled result, and no publishing bias was observed. CONCLUSION PCOS women typically present with an increased NLR. Such an increase is independent of obesity and may be associated with glycolipid metabolic disorders.

J Obstet Gynaecol Res 2022; 48:973-979. [PMID: 35199410 DOI: 10.1111/jog.15141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2021] [Revised: 11/23/2021] [Accepted: 12/18/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is one of the most prevalent endocrine disorders in females of reproductive age, with a prevalence of 20%-33% in the general population. Interleukin (IL)-34 is a recently explored proinflammatory cytokine and is an important modulator in different disease types. However, the function of IL-34 in PCOS has yet to be investigated. OBJECTIVE The purpose of this study was to determine the IL-34 serum level in women with PCOS and to compare it to that of a relatively healthy control group. Focusing on its relationship with IL-6, TNF-α, and IL-1β and homeostatic model assessment for insulin resistance (HOMA-IR), triglyceride, and low-density lipoprotein cholesterol (LDL-C). MATERIALS AND METHODS In this study, blood samples were obtained from 100 women with PCOS and 100 healthy control women for the purpose of estimating their serum levels of IL-34, IL-6, TNF-α, and IL-1β using the enzyme-linked immunosorbent assay technique. RESULTS Serum levels of IL-34, IL-6, TNF-α, and IL-1β were all higher in PCOS women than in healthy controls, and the difference was highly statistically significant. Serum IL-34 concentration was positively correlated with IL-6, TNF-α, and IL-1β concentration. Additionally, serum concentrations of IL-34 were positively correlated with HOMA-IR, triglyceride, and LDL-C. CONCLUSION When compared to normal women, IL-34, IL-6, TNF-α, and IL-1β levels were highly statistically significant in PCOS, and these high levels were associated with other cytokines (IL-6, TNF-α, and IL-1β), HOMA-IR, triglyceride, and LDL-C.

Abstract
Background Obesity is responsible for high morbidity and mortality, both in developed and developing countries. It is associated with many chronic and metabolic diseases. Asymmetric dimethylarginine (ADMA) has been demonstrated to be a biomarker of endothelial dysfunction in humans and increased ADMA associated with cardiovascular disease (CVD) risk has been reported in many states. Neopterin (NP) produced by monocytes/macrophages in response to stimulation by interferon-gamma (IFN-γ) is emphasized in recent findings. The current study aims to investigate ADMA and NP levels which may assume a role in guiding the early diagnosis of coronary artery disease in obesity. Methods This is an original research study in which ADMA and NP levels of 50 patients (25 male/25 female) diagnosed with obesity were compared with those of 30 healthy individuals (15 male/15 female) as control. The high-performance liquid chromatography (HPLC) method was used while determining parameters. Results ADMA and NP levels in obese individuals were found to be significantly higher than in those enrolled in the control. ADMA values were found to be higher in obese subjects (0.71±0.24 μmol/L) as compared with levels found in healthy subjects (0.58±0.16 μmol/L) (p<0.05). A significant increase of serum neopterin levels was found in obese subjects (8.8±3.5 μmol/L) as compared with controls (4.9±1.69 μmol/L) (p<0.05). Also, there was a strong positive correlation between NP and ADMA values in obese individuals (r=0.954). Conclusions Our study revealed that obese subjects have higher ADMA and neopterin levels. These results demonstrated that both ADMA and NP levels may be potential risk factors for coronary heart disease in obesity.

Abstract
AIM To investigate the relationship between glomerular filtration rates (GFR), and homeostasis model assesment of insulin resistance (HOMA-IR), C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) in patients with polycystic ovary syndrome (PCOS). MATERIAL AND METHODS Thirty-one overweight and obese PCOS patients with body mass index (BMI)≥25kg/m2 and 25 non-obese PCOS patients with BMI<25kg/m2 were included into patients' group, while 23 overweight and obese, and 25 non-obese age-and BMI-matched healthy individuals (aged between 18 and 40 years), were enrolled as controls. Levels of serum creatinine, glucose, insulin, CRP, and complete blood count were measured. eGFR, HOMA-IR and NLR were also calculated. RESULTS In PCOS group, HOMA-IR (p=0.001), CRP (p=0.025) and waist hip ratio (WHR) (p=0.011) were higher than controls. In obese PCOS sub-group, HOMA-IR (p=0.004) and WHR (p=0.002) were higher than obese controls. In non-obese PCOS sub-group, HOMA-IR (p=0.001) were higher than non-obese controls. In obese PCOS sub-group; HOMA-IR (p=0.001) and CRP (p=0.001) levels were significantly higher than non-obese PCOS sub-group. In terms of other parameters, no significant difference was found between the groups. The analysis showed a negative correlation between GFR, and BMI and HOMA-IR in PCOS group, between GFR, WHR and insulin levels in obese PCOS sub-group, and between BMI, and HOMA-IR and NLR in non-obese PCOS sub-group. CONCLUSION Although HOMA-IR and CRP were higher in PCOS group, there was no difference in NLR and GFR levels between those with PCOS and controls.

Abstract
Abstract
BACKGROUND
A dynamic balance between pro- and anti-inflammatory factors contributes to regulating human female reproduction. Chronic low-grade inflammation has been detected in several female reproductive conditions, from anovulation to embryo implantation failure. C-reactive protein (CRP) is a reliable marker of inflammation that is extensively used in clinical practice. Recent studies quantified CRP in the serum of infertile women undergoing ART and suggested its potential for the prediction of ART reproductive outcomes.
OBJECTIVE AND RATIONALE
The first objective of this systematic review of the available literature was to evaluate the association between pre-implantation circulating CRP concentration and pregnancy rates in women undergoing ART. The second objective was to describe serum CRP concentration changes after early embryo implantation. The changes in circulating CRP throughout the ART cycle, clinical implications of CRP quantification for the management of women undergoing ART, and future therapeutic options will also be discussed.
SEARCH METHODS
The MEDLINE database was systematically searched from inception to March 2019 using the following key words: (C-reactive protein) AND (assisted reproductive techniques OR ovulation induction OR insemination OR in vitro fertilization). Only articles in English were considered. Studies were selected based on title and abstract. The full text of potentially relevant articles was retrieved and assessed for inclusion by two reviewers (S.B. and S.H.). The protocol was registered in the International prospective register of systematic reviews (PROSPERO; registration number: CRD148687).
OUTCOMES
In total, 10 studies were included in this systematic review. Most of these studies reported lower circulating CRP values before the window of implantation and higher circulating CRP values during the peri-implantation period in women with successful ART outcome (biochemical or clinical pregnancy) compared to women without a successful outcome. Several lifestyle factors and/or drugs that reduce the concentration of circulating CRP significantly improve ART outcomes. Subgroup analyses according to female BMI and baseline circulating CRP concentration are highly recommended in future analyses.
WIDER IMPLICATIONS
These findings highlight a possible detrimental impact of preconception high circulating CRP concentration on ART outcomes. However, the biochemical or clinical pregnancy rate endpoints used in the studies examined here are insufficient (there were no data on live birth outcome), and the impact of major variables that can influence CRP and/or ART, for example maternal age, BMI, number of transferred embryos, and use of anti-inflammatory drugs, were not considered in the analyses. CRP quantification may be a potential marker of ART outcome, but its predictive value still needs to be investigated in large prospective studies. In future, the quantification of circulating CRP before starting ART could help to identify patients with a poor ART prognosis, leading to ART cycle cancellation or to preconception treatment to minimize the medical risks and costs.

Abstract
BACKGROUND Riboflavin, vitamin B-6, and vitamin B-12 are key players in one-carbon metabolism as enzymatic cofactors, and deficiency of these nutrients may influence reproductive outcomes possibly through affecting reproductive hormones. OBJECTIVE The goal was to investigate associations between dietary intakes of riboflavin, vitamin B-6, and vitamin B-12, and menstrual function among premenopausal women. DESIGN This was a secondary analysis of a prospective cohort study conducted at the University at Buffalo during 2005 to 2007. PARTICIPANTS/SETTING Participants were 259 healthy, regularly menstruating women (aged 18 to 44 years) with self-reported menstrual cycles between 21 and 35 days, who were not trying to conceive, and who had not used hormonal contraception during the past 3 months. MAIN OUTCOME MEASURES Intakes of B vitamins were assessed via 24-hour dietary recalls four times per menstrual cycle for two cycles. Serum reproductive hormones and plasma homocysteine were measured eight and three times, respectively, per cycle for two cycles. Anovulatory cycles were determined by progesterone concentrations ≤5 ng/mL (15.9 nmol/L) and no observed serum luteinizing hormone peak during the mid or late luteal phase visit. STATISTICAL ANALYSIS Weighted linear mixed regressions were used to evaluate associations between cycle-averaged B vitamin intakes and hormones and homocysteine, and generalized linear regressions for associations with anovulation. Models were adjusted for age, race, body mass index, physical activity, alternate Mediterranean diet score, intakes of total energy, protein, fiber, and folate, and percentage of energy intake from fat. RESULTS Higher intakes of riboflavin (per 0.1 mg increase in intake) were inversely correlated with estradiol (-0.87%, 95% CI -1.67 to -0.06) and homocysteine levels (-0.61%, 95% CI -1.10 to -0.12). Higher vitamin B-6 intakes were suggestive of higher follicle-stimulating hormone, although the results were not statistically significant (0.63% difference, 95% CI -0.03 to 1.29, per 0.1 mg increase in intake; P=0.06). Small increases in testosterone and decreases in homocysteine were found with vitamin B-12 intake. No associations were observed between intake of B vitamins and a risk of sporadic anovulation. CONCLUSIONS Higher intakes of riboflavin were associated with a small decrease in serum estradiol among healthy, regularly menstruating women. Higher intakes of riboflavin and vitamin B-12 were associated with lower plasma homocysteine concentrations. Overall, riboflavin, vitamin B-6, and vitamin B-12 that are one-carbon nutrients do not appear to influence the ovarian cycle among premenopausal women.

Abstract
Background Polycystic ovary syndrome (PCOS) is associated with low-grade inflammation, adipocyte hypertrophy, hyperglycemia, increased serum testosterone levels, and reduced lipolysis. This study aimed to investigate the role of interleukin-6 (IL-6) and IL-11 in the pathophysiology of adipocyte hypertrophy in a rat model of PCOS. Material/Methods The rat model of PCOS was developed using a subcutaneous injection of dehydroepiandrosterone (DHEA). Histology of the rat ovaries was used to confirm the development of PCOS. Serum levels of testosterone and glucose were measured. Immunohistochemistry, immunofluorescence, quantitative real-time polymerase chain reaction (qRT-PCR), and Western blot were performed to measure IL-6 and IL-11 in the rat model of PCOS. Cell proliferation was measured using the cell counting kit-8 (CCK-8) assay. Results Serum levels of testosterone and glucose and the expression of IL-6 and IL-11 were significantly increased in the rat model of PCOS via the activation of AKT/STAT3 signaling. Following IL-6 and IL-11 stimulation of mesenchymal adipocytes isolated from adipose tissue, IL-6 and IL-11 induced cell proliferation through the STAT3/AKT signaling pathway. Conclusions In a rat model of PCOS, increased expression of IL-6 and IL-11 was associated with the AKT/STAT3 pathway. Increased levels of IL-6 and IL-11 stimulated adipocytes from adipose tissue of the rat model, which promoted cell proliferation by activating AKT/STAT3 signaling.

Abstract
OBJECTIVE Multiple studies have explored the association between serum or plasma vitamin B12 status and obesity, in part because of the relationship between elevated homocysteine concentrations and atherosclerosis. This review will address the inconsistent finding of these studies with the objective of determining whether vitamin B12 concentrations are lower in people with higher body mass indices. DESIGN MEDLINE and EMBASE were searched to February 2017. Observational studies in general and clinical populations comparing serum/plasma B12 concentrations across groups of different body mass indices were selected. We did network and pairwise meta-analyses of serum/plasma B12, folate and homocysteine using frequentist techniques. Evidence-based items potentially indicating risk of bias were assessed. RESULTS Of 844 citations, we identified 19 eligible observational studies with 7,055 participants. The overall network, while showing no significant inconsistency between indirect and direct comparisons (P = 0.34), was qualitatively inconsistent. Based on the results of the meta-regression, in an exploratory sub-network meta-analysis where obesity groups were combined, we excluded disease-specific populations and studies with inadequate description of populations. The direction of the indirect and direct evidence was consistent. The pairwise results from this sub-network showed lower levels of B12 in people with higher body mass indices: obesity versus control difference in means (MD) -56 pmol L-1 (95% CI -90, -23), obesity versus overweight MD -21 pmol L-1 (95% CI -37, -5) and overweight versus control MD -51 pmol L-1 (95% CI -51, -24). Heterogeneity remained very large for most comparisons, and all the studies carried a high risk for bias. CONCLUSIONS This review did not establish an inverse association (or J-curve) between serum or plasma B12 concentrations and body mass index, but the direct pairwise evidence is consistent with an inverse association and supports further investigation.

Abstract
Abstract
Objective
The pathophysiologic features of polycystic ovary syndrome (PCOS) seem to be a combination of genetic predisposition and environmental factors. However, data regarding the exact effect of oxidative stress on PCOS is conflicting. This cross sectional and case-control study was designed to compare the serum ischemia modified albumin (IMA) levels in adolescent and young girls with and without PCOS.
Methods
A total of 41 non-obese adolescents and young girls (15–21 years) diagnosed as PCOS and 41 age and body mass index (BMI) matched controls were enrolled to study. The main features of PCOS and markers of chronic inflammation were determined together with serum IMA levels at the time of study enrollment.
Results
The C-reactive protein and neutrophil-to-lymphocyte ratio were within the normal ranges and also there were no significant difference between the two groups (p>0.05). Serum levels of IMA were significantly increased in adolescents with PCOS respect to healthy controls (0.44±0.12 versus 0.35±0.10 absorbance units, p<0.001). And also there was a significant positive correlation between serum IMA and BMI in all groups (r=0.274, p=0.013).
Conclusion
Serum IMA levels were higher in PCOS patients than in the healthy controls. This elevation may contribute to the increased cardiovascular diseases risk in PCOS patients.

Abstract
OBJECTIVE(S) The aim of our study is to analyse the inflammatory markers and lipid accumulation product (LAP) index in nonobese adolescents and younger aged women with polycystic ovary syndrome (PCOS) compared with age and body mass index (BMI)-matched healthy controls and to determine whether the investigated parameters are potential markers for the etiopathogenesis of PCOS. We also aim to determine whether these inflammatory markers are predictive for developing some clinical implications, such as cardiovascular disease (CVD) and insulin resistance (IR), associated with PCOS. STUDY DESIGN A total of 34 adolescents and younger aged females with PCOS, and 33 age and BMI-matched healthy controls were recruited for our study. All participants were nonobese (BMI<25). Neopterin (NEO), C-reactive protein (CRP) levels and complete blood parameters were assessed. LAP index and homeostasis model assessment of IR (HOMA-IR) were calculated; anthropometric, clinical and biochemical parameters were also recorded. RESULTS Serum NEO, CRP levels and LAP index were significantly increased in nonobese adolescents and younger aged females with PCOS compared to healthy controls. We could not found any predictive effect of investigated inflammatory markers and LAP index on CVD risk among PCOS patients after adjustment for abdominal obesity. We also found a positive predictive effect of WBC and a negative predictive effect of lymphocytes on IR in PCOS patients after adjustment for abdominal obesity. We did not find any predictor effect of NEO on IR, but it was a positive predictive marker for an elevated HOMA-IR index. CONCLUSION(S) Elevated NEO, CRP levels and LAP index could have potential roles in the etiopathogenesis of PCOS in nonobese adolescents and younger aged females,NEO could be a predictive marker for elevated HOMA-IR index, and WBC and lymphocytes could be predictive for the development of IR among nonobese adolescents and younger aged females with PCOS.

Clomiphene Citrate Treatment Cycle Outcomes of Polycystic Ovary Syndrome Patients Based on Basal High Sensitive C-Reactive Protein Levels: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF FERTILITY & STERILITY 2017; 10:320-326. [PMID: 28042411 PMCID: PMC5134747 DOI: 10.22074/ijfs.2016.4849] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Accepted: 07/07/2016] [Indexed: 12/03/2022]
Abstract
Background Polycystic ovary syndrome (PCOS) is highly associated with an ovulatory
infertility, features of the metabolic syndrome, including obesity, insulin resistance and
dyslipidemia. Serum concentrations of high sensitive C-reactive protein (hs-CRP) were
significantly higher in obese than in non-obese PCOS patients at baseline, suggesting a
relationship between elevated hs-CRP levels and obesity. The aim of this study was to
evaluate whether cycle day 3 hs-CRP levels before clomiphene citrate (CC) treatment
would predict cycle outcomes in women with PCOS. Materials and Methods This cross-sectional study was conducted among 84 infertile
women with PCOS who were treated with CC at Zekai Tahir Burak Women’s Health
Education and Research Hospital, Ankara, Turkey, between January 2014 and January
2015. Based on the exclusion criteria, cycle outcomes of remaining 66 infertile women
with PCOS treated with CC were analyzed. The hs-CRP levels and insulin resistance indexes
were evaluated on day 3 of the CC treatment cycle. The primary outcome measures
were number of preovulatory follicles measuring≥17 mm and pregnancy rates. Results The mean ± SD age of the patients was 24.0 ± 3.8 years (range 18-36). The mean
± SD body mass index (BMI) of the patients was 25.7 ± 4.9 (range 17-43). Fifty patients
developed dominant follicle (75%) and 5 patients established clinical pregnancy during
the study (clinical pregnancy rate: 7%). The mean ± SD baseline hs-CRP, fasting insulin
and Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) values of the
patients with and without dominant follicle generation during treatment cycle were 6.42 ±
7.05 and 4.41 ± 2.95 (P=0.27), 11.61 ± 6.94 and 10.95 ± 5.65 (P=0.73), 2.68 ± 1.79 and
2.41 ± 1.30 (P=0.58), respectively. The mean ± SD baseline hs-CRP, fasting insulin and
HOMA-IR values of the patients with and without clinical pregnancy establishment
following treatment cycle were 6.30 ± 2.56 and 5.90 ± 6.57 (P=0.89), 11.60 ± 7.54 and 11.44
± 6.61 (P=0.95), 2.42 ± 1.51 and 2.63 ± 1.70 (P=0.79), respectively. Conclusion In this study, we did not observe a predictive value of cycle day 3 hs-CRP
levels on preovulatory follicle development and pregnancy rates among infertile PCOS
patients treated with CC. Also, no relationship between HOMA-IR values and dominant
follicle generation or clinical pregnancy establishment was demonstrated in our study,
confirming the previous studies emphasizing the neutral effect of metformin utilization
before and/or during ovulation induction to pregnancy rates.

Abstract
The objective of the study is to assess the TNF-α levels in PCOS patients and healthy controls. A comprehensive electronic search in Medline, Embase, and the Cochrane Library database was conducted up to July 2016. Random-effects model was used to estimate the standardized mean differences (SMDs) with 95% confidence intervals (CIs). Twenty-nine studies with a total of 1960 participants (1046 PCOS patients and 914 controls) were included in this meta-analysis. The TNF-α levels in PCOS patients were significantly higher than those in controls (random-effects, SMD = 0.60, 95% CI = 0.28-0.92, P<0.001). With regard to the subgroup analyses stratified by ethnicity, study quality, methods, and BMI, significantly high TNF-α levels were found in patients with PCOS in almost all of these subgroups. In the subgroup stratified by HOMA-IR ratio and T ratio, significant differences were only observed in the subgroups with HOMA-IR ratio of >1.72(SMD = 0.967, 95% CI = 0.103-1.831, P = 0.028, I2 = 93.5%) and T ratio>2.10 (SMD = 1.420, 95% CI = 0.429-2.411, P = 0.005, I2 = 96.1%). By meta-regression it was suggested that ethnicity might contribute little to the heterogeneity between the included studies. Through cumulative meta-analysis and sensitivity analysis it was supposed that the higher TNF-α levels of PCOS patients compared to healthy controls was stable and reliable. This meta-analysis suggests that the circulating TNF-α levels in women with PCOS are significantly higher than those in healthy controls. It may be involved in promoting insulin resistance and androgen excess of PCOS.

Abstract
OBJECTIVE To investigate the inflammatory markers in polycystic ovary syndrome (PCOS) and associations of these markers with obesity and in vitro fertilization (IVF) outcomes. METHODS A total of 292 women underwent IVF procedure either with PCOS (n = 146) or without PCOS (n = 146, age, and body mass index (BMI) matched controls) were included in the study. All patients were classified according to BMI levels (normal weight: NW, BMI <25 kg/m(2) and obese: OB, BMI ≥25 kg/m(2)). The inflammatory markers were leukocyte count, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV). RESULTS BMI of PCOS was positively correlated with leukocyte, neutrophil, lymphocyte and MPV (p < 0.05), but negatively correlated with NLR and PLR (p < 0.05). Both NLR and PLR increased significantly in PCOS (p < 0.001). PLR increased significantly in NW-PCOS compared the NW-controls and OB-PCOS. MPV values increased only in OB-PCOS subjects. The logistic regression analyzes showed that MPV was the independent variable in PCOS to effect CPR (p = 0.000; OR 0.1; CI 0.06-0.2). CONCLUSIONS NLR and PLR were significantly increased in all PCOS subjects compared to the BMI-matched controls. Despite PLR being decreased by adiposity, PLR increased in NW-PCOS. These results are supporting the hypothesis that PCOS is a chronic inflammatory process independent of obesity. MPV levels were independently associated with CPR in PCOS. Further prospective studies concerning inflammation and IVF outcomes of PCOS are needed.
