AbstractThe purpose of this study was to assess the rate of insulin resistance (IR) and the relationship between IR and high-molecular weight adiponectin (HMWA) in patients with polycystic ovary syndrome (PCOS). A cross sectional study involving 43 women with PCOS and 39 normal women was carried out over a period of nine months. Fasting glucose and insulin levels, lipid parameters and androgen levels were measured in all serum samples. HMWA was determined by enzyme-linked immunosorbent assay and IR was estimated using the homeostasis model assessment of insulin resistance (HOMA-IR) index. The IR was more prevalent in the PCOS group than in the controls (p=0.002). Dehydroepiandrosterone sulfate, sex hormone binding globulin, free androgen index, total testosterone, insulin, and HOMA-IR levels were significantly higher in the PCOS group as compared to the control group (all p<0.05). Moreover, HMWA was significantly lower and negatively correlated with the clinical and biochemical hyperandrogenism in the PCOS group. HMWA and HOMA-IR were also associated with triglyceride, body mass index, and fat mass in this group. ROC curve analyses demonstrated that the AUC, indicative of the HMWA value for discriminating PCOS with IR, was 0.725, with a confidence interval of 0.615–0.835 (p=0.001). The serum HMWA levels are lower in patients with PCOS, which suggest that HMWA might be involved in the pathogenesis of PCOS. We also conclude that HMWA might be a strong determinant of IR in PCOS patients.

ObjectiveAdiponectin, an abundant adipokine with insulin-sensitizing properties, exists in different multimeric forms, including low-molecular weight, medium-molecular weight, and high-molecular weight (HMW) species. Alterations in the distribution of adiponectin multimers and the relationship between adiponectin multimers and insulin resistance (IR) in women with polycystic ovary syndrome (PCOS) remain unclear. The objective of this study was to compare adiponectin multimerization status and estimate insulin sensitivity in Chinese women with PCOS compared with age- and body mass index (BMI)-matched controls.MethodsCross-sectional study involving 64 Chinese women with PCOS and 59 normal women. Circulating total adiponectin and its multimeric forms were determined by ELISA, and IR was estimated using the homeostasis model assessment IR index (HOMA-IR).ResultsAfter controlling for BMI status, levels of both total and HMW adiponectin were significantly lower in women with PCOS compared with normal women (P<0.05). Furthermore, HMW adiponectin provided a stronger contribution to models predicting IR than total adiponectin. Lastly, decreased HMW adiponectin was associated with increased HOMA-IR in both normal and PCOS women, and this association was independent of both overall adiposity and visceral adiposity.ConclusionLevels of both total and HMW adiponectin were decreased in Chinese women with PCOS compared with normal control women, and the differences in HMW adiponectin persisted after controlling for BMI. Furthermore, HMW adiponectin is a stronger predictor of IR than total adiponectin in both women with PCOS and normal women.

Abstract Objective: Polycystic ovary syndrome (PCOS) is linked with metabolic syndrome, which includes obesity, insulin resistance, dyslipidemia, and endocrine function in patients with PCOS. The aim of this study was to determine the prevalence of adolescent PCOS and characteristics associated with PCOS in adolescents in Babol, Iran. Materials and methods: A cross-sectional study was conducted on 1549 girl high school students aged 16–20 years who were living in Iran. After overnight fasting, blood samples were collected to determine hormones and lipid levels in PCOS patients between the first and fifth days of their menstrual period or withdrawal bleeding. Results: The overall prevalence of adolescent PCOS was 129 (8.3%) (95% CI; 4.0, 12.0). Irregular menstruation was observed in 24.1% of adolescents. A total of 68% of PCOS adolescents had insulin resistance. Compared with non-PCOS adolescents, the OR of adolescent PCOS for family history of hirsutism was 1.53 (95% CI, 1.06–2.20; p=0.024), family history of irregular menstrual cycle was 2.27 (95% CI, 1.56–3.30; p<0.001), menarche age <13 years was 1.95 (95% CI, 1.36–2.81; p<0.001), hirsutism was 1.14 (CI 95%, 1.10–1.17; p<0.001), acne was 5.10 (CI 95%, 3.52–7.40; p<0.001), and wrist circumference was 1.28 (CI 95%, 1.07–1.54; p=0.007). Conclusion: The presenting findings showed the high prevalence of PCOS among Iranian adolescents. Emphasis should be placed on clinical screening in adolescents with high-risk factors, including irregular menstrual, menarche <13 years, hirsutism, acne, high wrist circumference, and paternal obesity to help reduce the risk of developing metabolic disturbance and to find ways to improve long-term health.
