Astaxanthin supplementation impact on insulin resistance, lipid profile, blood pressure, and oxidative stress in polycystic ovary syndrome patients: A triple-blind randomized clinical trial. Phytother Res 2024; 38:321-330. [PMID: 37874168 DOI: 10.1002/ptr.8037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 09/18/2023] [Accepted: 09/29/2023] [Indexed: 10/25/2023]
Abstract
Astaxanthin (ASX) is a natural carotenoid compound found in several of microorganisms and seafood. It may have numerous therapeutic benefits for polycystic ovarian syndrome (PCOS) patients. The aim of this study was to investigate the effect of ASX on lipid profile, insulin resistance (IR), blood pressure (BP), and oxidative stress (OS) levels in infertile PCOS patients. Overall, 58 infertile women with diagnosed PCOS participated in this triple-blind randomized clinical trial. They were randomly assigned to two groups, taking either a placebo or ASX (2 × 6 mg/day) for 8 weeks. Blood serum samples were collected from patients before and after the intervention. Fasting Insulin (FI), fasting blood glucose (FBS), OS markers (malondialdehyde [MDA], superoxide dismutase [SOD], and total antioxidant capacity [TAC]), and lipid profiles were evaluated in serum. Moreover, based on the relevant formula, several indices associated with IR were calculated. BP was also assessed at the start and end of the study. After 8 weeks of ASX consumption, a significant reduction was observed in fasting blood sugar, HOMA-IR, FI, MDA, low-density lipoprotein-cholesterol, and TC/HDL-C. Conversely, ASX significantly increased TAC, HDL-C, and QUICKI. After adjusting the analysis for the baseline values of age, body mass index, and biochemical parameters, non-significant values were obtained for QUICKI and FI, along with no changes in other findings. Overall, ASX appears to be an effective and safe supplement that alleviates insulin metabolism, lipid profile parameters, and OS in infertile PCOS patients.

Wang W, Tang X, Jiang Q, Niu Y, Wang Z, Wei D. Risk factors for clinical pregnancy loss after IVF in women with PCOS. Reprod Biomed Online 2023; 46:107-114. [PMID: 36396532 DOI: 10.1016/j.rbmo.2022.10.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 09/25/2022] [Accepted: 10/07/2022] [Indexed: 11/07/2022]
Abstract
RESEARCH QUESTION Which factors are associated with the risk of clinical pregnancy loss in women with polycystic ovary syndrome (PCOS) undergoing IVF? DESIGN Case-control study nested in a multicentre randomized trial comparing live birth rates between fresh and frozen embryo transfer in women with PCOS. Women with the outcome of clinical pregnancy loss were selected as the case group, those with live birth as the control group. Parameters before IVF treatment and variables during ovarian stimulation and embryo transfer were compared. RESULTS Women with clinical pregnancy loss had higher maternal body mass index (BMI, P = 0.010), anti-Müllerian hormone (AMH, P = 0.032), 2-h glucose concentration after 75 g oral glucose tolerance test (OGTT, P = 0.025), and a higher proportion of fresh embryo transfers (P = 0.001). There were significant interactions between the types of transfer and antral follicle count (AFC, P = 0.013), 2-h glucose concentration after OGTT (P = 0.024) on clinical pregnancy loss in PCOS, indicating that these factors may have different effects on pregnancy loss after fresh versus frozen embryo transfer. When the multivariable logistic regression analysis was stratified by the fresh or frozen embryo transfer, AFC (adjusted odds ratio [aOR] 1.03, 95% confidence interval [CI] 1.01-1.05) was a risk factor for clinical pregnancy loss after fresh embryo transfer, while 2-hour glucose concentration after OGTT (aOR 1.13, 95% CI 1.01-1.25) was associated with clinical pregnancy loss in frozen embryo transfer (FET) cycles. CONCLUSIONS In women with PCOS, fresh embryo transfer, higher BMI, AFC and 2-h glucose concentration after OGTT were risk factors for clinical pregnancy loss. FET may be a better choice to decrease the risk of clinical pregnancy loss, especially for those with higher AFC. During FET, 2-h glucose after OGTT appears to be associated with clinical pregnancy loss and warrants close monitoring.

Abstract
BACKGROUND There is scanty data in India on polycystic ovary syndrome (PCOS) from several small, undersized, convenience-based studies employing differing diagnostic criteria and reporting varied regional prevalence. It is difficult to draw clear-cut conclusions from these studies; therefore, the present multicentric, well-designed, large-scale representative countrywide epidemiological study on PCOS across India was conceived with the aim to generate the actual prevalence rates of PCOS in India with a total sample size of approximately 9000 individuals. OBJECTIVE The primary objectives of the study are to estimate the national prevalence of PCOS in India and the burden of comorbidities and to compare the variation in efficacy of standard therapeutic modalities for metabolic dysfunction in women with PCOS. METHODS This multicentric umbrella study consists of three different substudies. Substudy 1 will involve recruitment of women aged 18-40 years using a multistage sampling technique from randomly selected polling booths across urban and rural areas to estimate national prevalence, phenotypic variation, and risk factors among regions. Substudy 2 involves recruitment of subjects from the community pool of substudy 1 and the institutional pool for quantitation of comorbidities among women with PCOS. Substudy 3, an interventional part of the study, aims for comparison of variation in efficacies of common treatment modalities and will be conducted only at 2 centers. The eligible consenting women will be randomized in a 1:1 ratio into 2 arms through a blinding procedure. All these women will undergo clinical, biochemical, and hormonal assessment at baseline and at 3 and 6 months. The data generated will be analyzed using the reliable statistical software SPSS (version 26). RESULTS The study is ongoing and is likely to be completed by April 2022. The data will be compiled and analyzed, and the results of the study will be disseminated through publications. CONCLUSIONS The Indian Council of Medical Research-PCOS study is the first of its kind attempting to provide accurate and comprehensive data on prevalence of PCOS in India.

High BMI and Insulin Resistance Are Risk Factors for Spontaneous Abortion in Patients With Polycystic Ovary Syndrome Undergoing Assisted Reproductive Treatment: A Systematic Review and Meta-Analysis. Front Endocrinol (Lausanne) 2020; 11:592495. [PMID: 33343510 PMCID: PMC7744738 DOI: 10.3389/fendo.2020.592495] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Accepted: 11/05/2020] [Indexed: 12/17/2022] Open
Abstract
Background The risk of spontaneous abortion in patients with polycystic ovary syndrome (PCOS) undergoing assisted reproductive treatment (ART) is higher than that in patients without PCOS, however, no definitive risk factors have been confirmed to associate with the high spontaneous abortion rate in PCOS patients undergoing ART. This study was performed to assess the impact of relevant risk factors on spontaneous abortion in patients with PCOS. Clinical questions were formulated and organized according to the PICOS principle. Methods A systematic review and meta-analysis were conducted on all published studies on PCOS and spontaneous abortion in Embase, PubMed, Web of Science and Cochrane Library. Related risk factors included body mass index (BMI), age, insulin resistance (IR), hyperandrogenism, and chromosome aberrations. All patients were diagnosed as PCOS using the Rotterdam criteria. The primary endpoint was miscarriage and live birth rate. Fixed-effect models were used to analyze homogeneous data, and subgroup and sensitivity analyses were performed on heterogeneous data. The source of heterogeneity was evaluated, and the random effect model was used to summarize the heterogeneity. Results Among 1836 retrieved articles, 22 were eligible and included in the analysis with 11182 patients. High BMI (OR = 1.48, 95% CI [1.32, 1.67], MD = 1.35, 95% CI [0.58,2.12]) and insulin resistance (MD = 0.32, 95% CI [0.15, 0.49]) were associated with an increased risk of spontaneous abortion in PCOS patients undergoing ART. Older age (OR = 0.29, 95% CI [0.29, 0.44], MD = 2.01, 95% CI [0.04, 4.18]), embryonic chromosomal aberrations (OR = 0.75, 95%CI [0.31,1.77]), and hyperandrogenism (MD = 0.10, 95% CI [- 0.02, 0.22]) were not associated with the high spontaneous abortion rate in patients with PCOS. A subgroup analysis of BMI showed that there was no statistically significant difference in the effect between overweight and obesity on spontaneous abortion in PCOS patients undergoing ART (OR = 1.34, 95% [0.97, 1.85]). Conclusion High BMI and insulin resistance are two risk factors for an increased risk of spontaneous abortion in PCOS patients undergoing ART, and losing weight and mitigating insulin resistance may decrease the spontaneous abortion rate in these patients undergoing ART.

Abstract
Polycystic ovary syndrome (PCOS) is widely accepted as the most common endocrine abnormality in women of childbearing age and may be accompanied by dyslipidemia, hyperandrogenism, hyperinsulinemia, oxidative stress and infertility. Dyslipidemia is now known to play an important role in the development of PCOS. Lipid abnormalities, including elevated low-density lipoprotein and triglyceride levels and reduced high-density lipoprotein levels, are often found in women with PCOS and play an important role in PCOS; therefore, we summarize the effect of lipid abnormalities on hyperandrogenism, insulin resistance, oxidative stress and infertility in PCOS and review the effects of common lipid-lowering drugs on patients with PCOS. The purpose of this article is to elucidate the mechanisms of lipid metabolism abnormalities in the development of PCOS.

Abstract
PURPOSE Polycystic ovarian syndrome (PCOS) is a common cause of female infertility. Factors other than anovulation, such as low embryo quality have been suggested to contribute to the infertility in these women. This 2-year retrospective study used timelapse technology to investigate the PCOS-influence on timing of development in the pre-implantation embryo (primary endpoint). The secondary outcome measure was live birth rates after elective single-embryo transfer. METHODS In total, 313 embryos from 43 PCOS women, and 1075 embryos from 174 non-PCOS women undergoing assisted reproduction were included. All embryos were monitored until day 6. Differences in embryo kinetics were tested in a covariance regression model to account for potential confounding variables: female age, BMI, fertilization method and male infertility. RESULTS Time to initiate compaction and reach the morula stage as well as the duration of the 4th cleavage division was significantly shorter in PCOS embryos compared with non-PCOS embryos. No other kinetic differences were found at any time-points annotated. The proportion of multi-nucleated cells at the 2-cell stage was significantly higher in PCOS embryos compared with non-PCOS embryos. The live birth rates were comparable between the two groups. CONCLUSION The findings suggest that the causative factor for subfertility in PCOS is not related to timing of development in the pre-implantation embryo.

Abstract
Acute uterine bleeding unrelated to pregnancy has been defined as bleeding "sufficient in volume as to, in the opinion of the treating clinician, require urgent or emergent intervention." The Southern California Permanente Medical Group updated its guidelines for the management of this condition on the basis of the best available evidence, as identified in a systematic review of the available literature. Given the paucity of studies evaluating this condition, the guidelines, by necessity, include recommendations largely based on opinion or other sources such as case series that are, in general, categorized as low-quality evidence. Medical interventions with single or combined gonadal steroidal agents administered parenterally or orally show promise, but more high-quality studies are needed to better define the appropriate drugs, dose, and administrative scheduling. There is also some evidence that intrauterine tamponade may be useful in at least selected cases. Special attention must be paid to both diagnosing and treating inherited disorders of hemostasis, such as von Willebrand disease, that may otherwise be underdiagnosed in both adolescent and adult women.

Abstract
Obesity is a major international problem related to many reproductive health problems including polycystic ovary syndrome (PCOS). This article reviews the evidence of being overweight and its effect on female reproduction. The fecundity of obese women is lower than normal weight women, but there is no absolute consensus about the effect of obesity on infertility treatment. The obese patient might have oocyte, hormone, metabolic and endometrial dysfunction affecting reproduction. Insulin and leptin may be some of the answers explaining anovulation during obesity leading to infertility. Moreover, the follicular glucose and lipids which are important for oocyte development also increase in the obese patient and these might have an effect on oocyte quality because studies in mice have revealed that the obesity affects follicular cell stress and oocyte lipids. Overall, obesity affects female reproduction by disturbing the general body metabolism, hormone metabolism and the follicular environment.

Abstract
OBJECTIVE The objective of this study was to compare the impact of aging on nitric oxide (NO) modulation of platelet and vascular function in healthy women and women with polycystic ovary syndrome. METHODS AND RESULTS A case-control study of women ages 18 to 60 years, comparing women with polycystic ovarian syndrome against age-matched healthy controls, was performed. A total of 242 women, of whom 109 had polycystic ovarian syndrome (based on Rotterdam criteria), participated in the study. Women who were pregnant or on clopidogrel were excluded from the study. Inhibition of platelet aggregation by nitric oxide (primary outcome measure), vascular endothelial function, plasma concentrations of N(G), N(G)-dimethyl-L-arginine (ADMA), endothelial progenitor cell count, and high-sensitivity C-reactive protein (markers of endothelial dysfunction and inflammation) were assessed. With increasing age in control women, there was progressive attenuation of platelet responses to NO, impairment of endothelial function, and elevation of ADMA levels (P ≤.001). Irrespective of age, women with polycystic ovarian syndrome exhibited greater impairment of all these parameters (all P <.05, 2-way analysis of variance) and demonstrated these anomalies earlier in life. CONCLUSIONS Normal aging in women is associated with attenuation of NO-based signaling in platelets and blood vessels. In women with polycystic ovarian syndrome, these changes are present from early adult life and may contribute to premature atherogenesis.

Abstract
There exists a spectrum of potential causes of abnormal uterine bleeding (AUB) in nonpregnant reproductive-aged women. In some instances the abnormal bleeding may emanate from definable pathologic entities in the endometrial cavity such as polyps or submucous leiomyomas (fibroids), while in others, it may occur secondary to coagulopathies or disorders of local or systemic hemostasis. If the patient is subjected to a rigorous evaluation more than one potential contributor may be identified, a circumstance that challenges the clinician since entities such as polyps, leiomyomas, and adenomyosis may frequently be asymptomatic, even in women with AUB. The bench or clinical investigator may also be influenced by the existence of the multiplicity of potential causes that could confound the results of research. This paper describes FIGO's (Fédération Internationale de Gynécologie et d'Obstétrique) new PALM-COEIN classification of causes of AUB in the reproductive years (Polyp, Adenomyosis, Leiomyoma, Malignancy and hyperplasia-Coagulopathy, Ovulatory disorder, Endometrial, Iatrogenic, Not yet classified). This system is designed to assist clinicians in the evaluation of patients, investigators in the design and interpretation of research and faculty in the education of medical students and residents/trainees. Additionally, given the longstanding existence of a confusing array of conflicting definitions, the manuscript describes the FIGO standardized terminology for both normal menstruation and AUB symptoms.

Abstract
Altered levels of matrix metalloproteinases (MMPs) may reflect relevant pathogenetic mechanisms of disease conditions. The objective of this study was to compare the plasma levels of MMPs and tissue inhibitors of MMPs (TIMPs) in polycystic ovary syndrome (PCOS) patients with those found in healthy ovulatory controls and to examine whether the levels of these biomarkers are associated with clinical and biochemical features of this syndrome. Sixty-five healthy ovulatory subjects (controls) and 80 patients with PCOS were include in this study. MMP-2, MMP-8, MMP-9, TIMP-1, TIMP-2 concentrations were measured in plasma samples by gelatin zymography or enzyme-linked immunoassays. MMP-2, MMP-8, MMP-9, and TIMP-1 levels were similar in PCOS patients and in healthy controls (P > 0.05). PCOS patients had lower plasma TIMP-2 levels than healthy controls (P < 0.05). We found higher MMP-2/TIMP-2 and MMP-9/TIMP-1 ratios in PCOS patients than in healthy controls (all P < 0.05). Testosterone levels correlated positively with the MMP-9/TIMP-1 ratio and negatively with TIMP-2 levels (r = 0.26, P < 0.01 and r = -0.21, P = 0.02, respectively). In addition, only testosterone was an independent predictor of TIMP-2 levels (estimate = -0.35, P = 0.04) and the MMP-9/TIMP-1 ratio (estimate = 0.01, P = 0.04). We found evidence indicating that the balance between MMPs and TIMPs in women with PCOS is altered, probably due to androgen excess found in these women.

Abstract
Platelet hyporesponsiveness to the anti-aggregatory effects of nitric oxide (NO) occurs commonly in association with myocardial ischemia and coronary risk factors, often co-exists with endothelial dysfunction and represents an independent marker of long-term cardiovascular risk. We sought to determine whether polycystic ovary syndrome (PCOS), which has been postulated as a cardiovascular risk factor in women, is independently associated with this phenomenon. Twenty-four young women with PCOS (mean age 32.1+/-1.3) were evaluated in lean (n=12) and obese (n=12) subgroups, and compared with age-matched lean normals (n=12). Platelet aggregation and its inhibition by the nitric oxide donor sodium nitroprusside (SNP) were assessed and compared with vascular endothelial function. Plasma concentrations of malondialdehyde (MDA), N(G),N(G)-dimethyl-L-arginine (ADMA) and hs-CRP were measured as markers of oxidative stress, endothelial dysfunction and inflammation, respectively. Circulating endothelial progenitor cell (EPC) counts were also documented. In both PCOS subgroups, which demonstrated hyperaggregability to ADP, responses to SNP inhibition of aggregation (the principal end-point of the study) were significantly impaired (P<0.01 for both), as were their endothelium-dependent vascular responses to salbutamol (P<0.05 for both). However, vasomotor responses to nitroglycerin and circulating EPC counts did not vary between groups. PCOS subjects also had significantly elevated ADMA, MDA and hs-CRP levels relative to normals (all P<0.05). Impairment of SNP response remained unaltered after mean 30+/-2.4 months follow-up in PCOS subjects. We conclude that in PCOS subjects, independent of obesity and associated insulin resistance, profound and reproducible impairment of platelet responsiveness to NO is an additional component of cardiovascular homeostatic disturbance.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) affects 5-10% of reproductive-aged women and is commonly associated with anovulatory infertility. Leukocytes, together with granulosa cells, may contribute to the pathogenesis of PCOS via their ability to secrete an array of cytokines implicated in follicle growth. The aim of this study was to examine leukocyte subtypes in follicular phase ovaries and to quantify cytokine and chemokine mRNA expression in follicular fluid cells obtained at the time of oocyte retrieval before IVF in women with and without PCOS. METHODS Ovaries were immunostained for various leukocyte markers [CD3, CD4, CD14, CD15, CD45, CD45RA, CD45RO, CD57 and major histocompatibility complex (MHC) class II]. In addition, follicular fluid cells were subjected to quantitative RT-PCR to evaluate colony-stimulating factor-1 (CSF-1), granulocyte-macrophage (GM)-CSF, interleukins (IL-1beta, IL-6, IL-8 and IL-10), monocyte chemotactic protein (MCP-1) and tumour necrosis factor (TNFalpha) mRNA expression relative to beta-actin. RESULTS CD45RO+ cells (activated/memory T lymphocytes) were reduced by 60% in the theca layer of follicles from PCOS women. The relative abundance of macrophages and neutrophils was unchanged. Cytokine and chemokine mRNA transcripts examined were not affected by PCOS status. There was an association between high BMI and high TNFalpha and low IL-6 mRNA expression in follicular cells. IL-6 expression was higher in women who subsequently achieved pregnancy. CONCLUSIONS T lymphocytes potentially play a role in the local pathological mechanisms of PCOS. Further studies are required to identify their contribution to the aetiology of this common condition.
