<p class="Abstract">In the present study 32 women with polycystic ovary syndrome were treated with glabridin (10 µM ) daily for 12 months. The results revealed a significant reduction in serum testosterone from 95.3 ± 23.6 to 49.8 ± 12.7 ng/dL and fasting insulin concentrations from 12.3 ± 5.2 to 8.11 ± 3.42 U/mL after glabridin treatment. It also leads to a marked improvement in insulin resistance indices and reduction in hirsutism score from 12.8 ± 3.2 to 7.0 ± 3.5. More interestingly, all the women reverted to regular menstrual cycles. The sex hormone-binding globulin level increased significantly from 23.1 ± 5.6 to 52.5 ± 15.8 nmol/L after glabridin treatment. The levels of serum hsCRP decreased from 0.32 ± 0.08 to 0.06 ± 0.01 mg/dL and that of endothelium-dependent vascular responses from 17.2 ± 4.3 to 8.8 ± 2.4% after glabridin treatment. Therefore, glabridin acts as a potent candidate for the improve-ment of insulin sensitivity and androgen production.</p><p> </p>

ObjectiveIncreased serum C-reactive protein (CRP), an independent predictor of coronary heart disease, was reported in women with polycystic ovary syndrome (PCOS). It remains unclear whether this finding is due to the association between PCOS and either insulin resistance, obesity, or androgen excess, which are all common features of this condition. The aims of this study were to assess whether increased serum CRP is a specific feature of PCOS and to investigate the mechanisms underlying this association.Design and methodsSerum high-sensitivity CRP (hs-CRP) was measured in 86 hyperandrogenic women (age 21.6±4.2 years, body mass index (BMI) 23.6±3.5 kg/m2), 50 with PCOS and 36 with idiopathic hyperandrogenism (HA). Thirty-five BMI-matched healthy women were also studied as controls. In these subjects, endocrine and metabolic profiles were assessed. In all hyperandrogenic subjects and 14 controls, insulin sensitivity was measured by the glucose clamp technique. Body fat was measured by bioelectrical impedance.ResultsHs-CRP concentrations were higher in PCOS women (3.43±2.01 mg/l) than in HA subjects and healthy women (2.43±1.04, P<0.005; and 2.75±0.86 mg/l, P<0.05 respectively versus PCOS). In multiple regression analyses, increased serum hs-CRP was independently predicted by higher body fat and lower insulin sensitivity. However, in lean women, serum-free testosterone was an additional, negative, predictive variable.ConclusionsPCOS is accompanied by a low-grade chronic inflammation. Body fat appears the main determining factor of this finding, which is only partly explained by insulin resistance. At least in lean women, androgen excess per se seems to play an additional, possibly protective, role in this association.

Background: Polycystic ovary syndrome (PCOS) is associated with insulin resistance and elevated risk of cardiovascular disease and diabetes. Chronic inflammation has been observed in PCOS in several studies but there is also opposing evidence and a dearth of research in Indians. Objective: To estimate chronic inflammation in PCOS and find its relationship with appropriate anthropometric and biochemical parameters. Materials and Methods: Chronic inflammation was assessed in 30 women with PCOS (Group A) and 30 healthy controls (Group B) with highly sensitive C-reactive protein (hsCRP), interleukin-6 (IL-6), tumour necrosis factor alpha (TNFα), and platelet microparticles (PMP). In group A, the relationship of chronic inflammation with insulin resistance, waist hip ratio (WHR) serum testosterone, and serum glutamate pyruvate transaminase (SGPT) were examined. Results: In group A, the hsCRP, TNFα, and PMP were significantly elevated compared to group B. However, IL-6 level was similar between the groups. In group A, PMP showed a significant positive correlation with waist-hip ratio and serum testosterone. IL-6 showed a significant positive correlation with insulin sensitivity and significant negative correlation with insulin resistance and serum glutamate pyruvate transaminase. Conclusion: PCOS is associated with chronic inflammation and PMP correlates positively with central adiposity and biochemical hyperandrogenism in women with PCOS.

OBJECTIVE: To determine the frequency of late-onset adrenal hyperplasia (LOCAH) due to 21-hydroxylase (21-OH) and 11 beta-hydroxylase (11 beta-OH) deficiency in women with clinical and biochemical features of polycystic ovary syndrome (PCOS). DESIGN: Eighty-three consecutively selected women with PCOS and eighteen normal women were included in the study. METHODS: Ultrasound, clinical and hormonal parameters were used to define PCOS. Basal FSH, LH, testosterone, free testosterone, androstenedione, dehydroepiandrosterone sulfate (DHEA-S), sex hormone-binding globulin (SHBG) and cortisol levels were measured. Serum 17-hydroxyprogesterone (17-OHP) and 11-deoxycortisol (11-DOC) levels were also measured before, 30 and 60 min after a single bolus injection of 0.25 mg ACTH (1-24) at 0900 h during the mid-follicular phase of the cycle. ACTH-stimulated 17-OHP levels > 30 nmol/l were considered as the criteria of 21-OH deficiency. The diagnosis 11 beta-OH deficiency was made if the adrenal 11-DOC response to ACTH stimulation exceeded threefold the 95th percentile of controls. RESULTS: Basal serum testosterone, free testosterone, androstenedione, DHEA-S, cortisol and 11-DOC levels were significantly higher in PCOS than in control subjects. ACTH-stimulated 17-OHP (P < 0.05) and 11-DOC (P < 0.0005) levels were found to be significantly higher in patients with PCOS than in controls. Seven (8.4%) patients had an 11-DOC response to ACTH higher than threefold the 95th percentile of controls, while no patients showed evidence of 21-OH deficiency. CONCLUSIONS: We have found that 8.4% of the women with clinical and biochemical features of PCOS could be presumed to have 11 beta-OH deficiency. No patients among the women with PCOS showed evidence of 21-OH deficiency. 11 beta-OH deficiency is unexpectedly more common than 21-OH deficiency in women with PCOS.
