Background: Women diagnosed with polycystic ovary syndrome (PCOS) suffer from an unfavorable cardiometabolic risk profile, which is already established by child-bearing age.Objective and Rationale: The aim of this systematic review along with an individual participant data meta-analysis is to evaluate whether cardiometabolic features in the offspring (females and males aged 1-18 years) of women with PCOS (OPCOS) are less favorable compared to the offspring of healthy controls.Search Methods: PubMed, Embase and gray literature databases were searched by three authors independently (M.N.G., M.A.W and J.C.) (last updated on 1 February 2018). Relevant key terms such as 'offspring' and 'PCOS' were combined. Outcomes were age-specific standardized scores of various cardiometabolic parameters: BMI, blood pressure, glucose, insulin, lipid profile and the sum scores of various cardiometabolic features (metabolic sum score). Linear mixed models were used for analyses with standardized beta (β) as outcome.Outcomes: Nine relevant observational studies could be identified, which jointly included 1367 children: OPCOS and controls, originating from the Netherlands, Chile and the USA. After excluding neonates, duplicate records and follow-up screenings, a total of 885 subjects remained. In adjusted analyses, we observed that OPCOS (n = 298) exhibited increased plasma levels of fasting insulin (β = 0.21(95%CI: 0.01-0.41), P = 0.05), insulin-resistance (β = 0.21(95%CI: 0.01-0.42), P = 0.04), triglycerides (β = 0.19(95%CI: 0.02-0.36), P = 0.03) and high-density lipoprotein (HDL)-cholesterol concentrations (β = 0.31(95%CI: 0.08-0.54), P < 0.01), but a reduced birthweight (β = -116(95%CI: -195 to 38), P < 0.01) compared to controls (n = 587). After correction for multiple testing, however, differences in insulin and triglycerides lost their statistical significance. Interaction tests for sex revealed differences between males and females when comparing OPCOS versus controls. A higher 2-hour fasting insulin was observed among female OPCOS versus female controls (estimated difference for females (βf) = 0.45(95%CI: 0.07 to 0.83)) compared to the estimated difference between males ((βm) = -0.20(95%CI: -0.58 to 0.19)), with interaction-test: P = 0.03. Low-density lipoprotein-cholesterol differences in OPCOS versus controls were lower among females (βf = -0.39(95%CI: -0.62 to 0.16)), but comparable between male OPCOS and male controls (βm = 0.27(95%CI: -0.03 to 0.57)), with interaction-test: P < 0.01. Total cholesterol differences in OPCOS versus controls were also lower in females compared to the difference in male OPCOS and male controls (βf = -0.31(95%CI: -0.57 to 0.06), βm = 0.28(95%CI: -0.01 to 0.56), interaction-test: P = 0.01). The difference in HDL-cholesterol among female OPCOS versus controls (βf = 0.53(95%CI: 0.18-0.88)) was larger compared to the estimated mean difference among OPCOS males and the male controls (βm = 0.13(95%CI: -0.05-0.31), interaction-test: P < 0.01). Interaction test in metabolic sum score revealed a significant difference between females (OPCOS versus controls) and males (OPCOS versus controls); however, sub analyses performed in both sexes separately did not reveal a difference among females (OPCOS versus controls: βf = -0.14(95%CI: -1.05 to 0.77)) or males (OPCOS versus controls: βm = 0.85(95%CI: -0.10 to 1.79)), with P-value < 0.01.Wider Implications: We observed subtle signs of altered cardiometabolic health in OPCOS. Therefore, the unfavorable cardiovascular profile of women with PCOS at childbearing age may-next to a genetic predisposition-influence the health of their offspring. Sensitivity analyses revealed that these differences were predominantly observed among female offspring aged between 1 and 18 years. Moreover, studies with minimal risk of bias should elucidate the influence of a PCOS diagnosis in mothers on both sexes during fetal development and subsequently during childhood.

Objective: To study the presence of several maternal and neonatal complications in a cohort of women with hyperandrogenic as well as normoandrogenic polycystic ovary syndrome (PCOS) and women with PCOS who received different fertility treatments.Design: Prospective multicenter cohort study.Setting: Hospitals and midwifery practices.Patient(s): One hundred and eighty-eight women with PCOS and singleton pregnancies (study group) and 2,889 women with a naturally conceived singleton pregnancy (reference group).Intervention(s): Observational study.Main Outcome Measure(s): Maternal and neonatal pregnancy complications.Result(s): Women with PCOS had a statistically significantly increased risk of developing gestational diabetes (adjusted odds ratio [AOR] 4.15; 95% confidence interval [CI], 2.07-8.33) compared with the reference group, and their infants were more often born small for gestational age (AOR 3.76; 95% CI, 1.69-8.35). In a subgroup analysis, maternal complications were statistically significantly more often present in women with hyperandrogenic (defined as a free androgen index >4.5) PCOS (n = 76; 40% of all PCOS women) compared with those with normoandrogenic PCOS (n = 97; 52% of all PCOS women) (45% vs. 24%; P=.003); no statistically significant differences were observed between these groups regarding neonatal complications.Conclusion(s): Women with PCOS have an increased risk of maternal and neonatal pregnancy complications, especially women with the hyperandrogenic phenotype.Clinical Trial Registration Number: NCT00821379.

Objective: To study metabolic/inflammatory biomarker risk profiles in women with PCOS and PCOS offspring. Design: Cross-sectional comparison of serum biomarkers. Setting: University Medical Center Utrecht. Patients: Hyperandrogenic PCOS women (HA-PCOS, n = 34), normoandrogenic PCOS women (NA-PCOS, n = 34), non-PCOS reference population (n = 32), PCOS offspring (n = 14, age 6–8 years), and a paedriatic reference population (n = 30). Main Outcome Measure(s): Clustering profile of adipocytokines (IL-1b, IL-6, IL-13, IL-17, IL-18, TNF-α, adiponectin, adipsin, leptin, chemerin, resistin, RBP4, DPP-IV/sCD26, CCL2/MCP-1), growth factors (PIGF, VEGF, sVEGF-R1), soluble cell adhesion molecules (sICAM-1/sCD54, sVCAM-1/sCD106), and other inflammatory related proteases (MMP-9, S100A8, Cathepsin S). Differences in median biomarker concentrations between groups, and associations with the free androgen index (FAI; Testosterone/SHBG x100). Results: The cluster analysis identified leptin, RBP-4, DPP-IV and adiponectin as potential discriminative markers for HA-PCOS with a specifically strong correlation in cases with increased BMI. Leptin (R2 = 0.219) and adiponectin (R2 = 0.182) showed the strongest correlation with the FAI. When comparing median protein concentrations adult PCOS women with or without hyperandrogenemia, the most profound differences were observed for leptin (P < 0.001), DPP-IV (P = 0.005), and adiponectin (P < 0.001). Adjusting for age, BMI and multiple testing attenuated all differences. In PCOS offspring, MMP-9 (P = 0.001) and S100A8 (P < 0.001) concentrations were significantly higher compared to a healthy matched reference population, even after correcting for age and BMI and adjustment for multiple testing. Conclusion: In this preliminary investigation we observed significant differences in adipocytokines between women with or without hyperandrogenic PCOS and non-PCOS controls, mostly influenced by BMI. Leptin and adiponectin showed the strongest correlation with the FAI in adult women with PCOS. In PCOS offspring other inflammatory biomarkers (MMP-9, S100A8) were increased, suggesting that these children may exhibit increased chronic low-grade inflammation. Additional research is required to confirm results of the current exploratory investigation. [ABSTRACT FROM AUTHOR]

Study Question: Are macroscopic and microscopic placental characteristics in a heterogeneous group of women diagnosed with polycystic ovary syndrome (PCOS) different from those of a low-risk general population?Summary Answer: Women with PCOS have significantly different microscopic placental characteristics compared with control women, independently from pregnancy complications.What Is Known Already: Non-obese women with PCOS who conceived spontaneously have a significantly reduced placental volume and weight, with more chronic villitis and intervillositis compared with healthy controls.Study Design, Size, Duration: A subset of a large prospective cohort study of pregnant women with PCOS was used. Healthy (low-risk) women who delivered at term after an uncomplicated pregnancy were used as the reference population. The placentas of 73 women with PCOS were analysed and compared with 209 placentas of healthy women.Participants/materials, Setting, Methods: Placentas were collected after delivery from women with PCOS who were followed from prior to conception until delivery. The placentas were macroscopically and microscopically analysed and compared with placentas of healthy women with either a spontaneous start of labour who delivered at term or who had an elective Caesarean section.Main Results and the Role Of Chance: After adjusting for potential confounders, placentas from women with PCOS showed more chorioamnionitis (P < 0.001), funisitis (P = 0.019), villitis (P = 0.045), thrombosis (P = 0.018), infarction (P = 0.010), villous immaturity (P = 0.009) and nucleated fetal red blood cells (P < 0.001). In a subgroup analysis, among women with and without pregnancy complications within the PCOS group, only the occurrence of thrombosis was increased in pregnancies complicated by pregnancy-induced hypertension or pre-eclampsia (30%, versus 0% in gestational diabetes pregnancies and 13% in uncomplicated pregnancies; P = 0.008).Limitations, Reasons For Caution: There might be a small proportion of women with PCOS in the reference group, since this group was not screened for PCOS. As a result, the observed difference may be an underestimation of the true difference. Placentas were stored for up to 72 h at 4°C, this is common practice but some degenerative changes cannot be ruled out absolutely. Also, there is possibility that baseline differences between the groups may in part explain some of the differences in placental pathology.Wider Implications Of the Findings: Our findings suggest that, in general, women with PCOS can have placental alterations associated with an increased hypoxic state, which seems not to be caused by the increased incidence of pregnancy complications.

background: The great majority of studies performed so far concerning women diagnosed with polycystic ovary syndrome (PCOS) have focused on diagnosis, menstrual cycle abnormalities, hirsutism and infertility. Although progress has been made in developing methods for achieving a pregnancy and reducing multiple gestations in women with PCOS, little attention has been paid to pregnancy complications and subsequent child outcomes. This review aims to summarize current knowledge regarding the clinical and pathophysiological features of pregnancy and children in women with PCOS. methods: A literature search up to April 2015 was performed in PubMed, Medline, the Cochrane Library andWeb of Science without language restriction. All articles were initially screened for title and abstract and full texts of eligible articles were subsequently selected. Systematic reviewswith meta-analysis were initially included for each specific subject. Recent randomised controlled trials (RCTs), which were not included in the systematic reviews, were also included. In addition to evidence from meta-analyses or RCTs, we used non-randomized prospective, uncontrolled prospective, retrospective andexperimental studies. When specific data for patientswithPCOSwere lacking, results fromgeneral populationstudieswere reported. results:Women withPCOSexhibit a clinically significant increased risk of pregnancycomplicationscompared with controls. Data whichwere not adjusted forBMI or otherconfounders demonstrated inPCOSa 3-4-fold increased risk of pregnancy-induced hypertension and pre-eclampsia, a 3-fold increased risk of gestational diabetes and 2-fold higher chance for premature delivery. Features characteristic of PCOS, such as hyperandrogenism, obesity, insulin resistance and metabolic abnormalities, may contribute to the increased risk of obstetric and neonatal complications. Limited available data suggest that offspring ofwomen withPCOShave an increased risk for futuremetabolic and reproductive dysfunction. Underlying pathophysiological mechanisms of pregnancy complications along with its association with health of offspring remain uncertain. To date, the strategies for prevention and management of pregnancy complications in women with PCOS, and whether long-term health of these women is influenced, and to what extent, by pregnancy and/or pregnancy complications, remain to be elucidated. conclusions: Women with PCOS show an increased risk of pregnancy complications. Heterogeneous aetiological factors involved in PCOS and associated co-morbidities may all be involved in compromised pregnancy and child outcomes. In women with PCOS, a possible relationship with genetic, environmental, clinical and biochemical factors involved in this complex condition, as well as with pregnancy complications and long-term health for both mother and child, remains to be established.
