Insulin resistance (IR) plays a pivotal role in PCOS. Insulin-sensitizer agents such as metformin and inositols have been shown to improve the endocrine and metabolic aspects of PCOS. The purpose of this study is to compare their effects on the clinical and metabolic features of the women with PCOS. Fifty PCOS women with IR and/or hyperinsulinemia were randomized to treatment with metformin (1500 mg/day) or myo-inositol (4 g/day). IR was defined as HOMA-IR >2.5, while hyperinsulinemia was defined as a value of AUC for insulin after a glucose load over the cutoff of our laboratory obtained in normal women. The Matsusa Index has been calculated. The women have been evaluated for insulin secretion, BMI, menstrual cycle length, acne and hirsutism, at baseline and after 6 months of therapy. The results obtained in both groups were similar. The insulin sensitivity improved in both treatment groups. The BMI significantly decreased and the menstrual cycle was normalized in about 50% of the women. No significant changes in acne and hirsutism were observed. The two insulin-sensitizers, metformin and myo-inositol, show to be useful in PCOS women in lowering BMI and ameliorating insulin sensitivity, and improving menstrual cycle without significant differences between the two treatments.

To our knowledge, data on comparison of myo-inositol and metformin on clinical, metabolic and genetic parameters in subjects with polycystic ovary syndrome (PCOS) are limited. This study was carried out to compare myo-inositol and metformin on clinical, metabolic and genetic parameters in subjects with PCOS. DESIGN, This randomized controlled trial was conducted among 60 subjects with PCOS aged 18-40 years. Subjects were randomly allocated into two groups to receive either myo-inositol (N=30) or metformin (N=30) for 12 weeks. Gene expression of inflammatory cytokines was assessed in peripheral blood mononuclear cells (PBMCs) of PCOS women by RT-PCR. After the 12-week intervention, compared with metformin, myo-inositol intake significantly decreased serum total testosterone (-1.4±4.2 vs +0.7±1.4 nmol/L, P=.03), modified Ferriman-Gallwey (mF-G) scores (-1.1±0.7 vs -0.5±0.8, P=.01) and serum high-sensitivity C-reactive protein (hs-CRP) levels (-2.6±3.9 vs +0.2±1.5 mg/L, P<.001). RT-PCR demonstrated that compared with metformin, myo-inositol downregulated gene expression of interleukin-1 (IL-1) (P=.02) in PBMCs of subjects with PCOS. We did not observe any significant effect of myo-inositol intake compared with metformin on other hormonal profiles, plasma nitric oxide (NO) or gene expression of IL-8 and tumour necrosis factor alpha (TNF-α). Overall, taking myo-inositol, compared with metformin, for 12 weeks in patients with PCOS with hyperinsulinism and normoinsulinism had beneficial effects on total testosterone, mFG scores, serum hs-CRP levels and gene expression of IL-1, but did not affect other hormonal profiles, NO levels or gene expression of IL-8 and TNF-α.
To investigate the relation between intra-abdominal fat distribution and metabolic disorders in nonobese patients with the polycystic ovary syndrome (PCOS). Prospective case-control study. University-based hospital. PATIENT(S): Thirty nonobese patients with PCOS and 30 lean women with regular menstrual cycles (controls). All participants had a body mass index < 25kg/m(2). Subcutaneous and intra-abdominal visceral and preperitoneal fat thicknesses were assessed by ultrasonography. Glucose tolerance and insulin sensitivity were evaluated by standard 75-g oral glucose tolerance test and area-under-the-curve analysis. Serum hormones and lipid profile were measured. RESULT(S): The mean preperitoneal and visceral fat thicknesses were significantly greater in nonobese patients with PCOS. Subcutaneous fat mass was similar between the PCOS and control groups. Nonobese patients with PCOS had glucose intolerance, hyperinsulinemia, and dyslipidemia, manifested by high serum levels of triglyceride, total cholesterol, and high-density lipoprotein (HDL) levels and low serum low-density lipoprotein (LDL) levels. No correlation existed between subcutaneous fat thickness and the metabolic variables in nonobese patients with PCOS. However, serum triglyceride levels correlated with visceral fat and preperitoneal fat thickness. The mean HDL level correlated negatively with visceral fat and preperitoneal fat thickness. The area under the curve for insulin and mean fasting insulin levels correlated positively with visceral fat thickness. In multiple regression analysis, visceral fat thickness contributed significantly to high serum triglyceride and fasting insulin levels. CONCLUSION(S): Intra-abdominal preperitoneal and visceral fat accumulation may contribute to the development of glucose and lipid metabolism disorders in nonobese patients with PCOS.
To evaluate the effect of N-acetyl-cysteine (NAC) on insulin secretion and peripheral insulin resistance in subjects with polycystic ovary syndrome (PCOS). Prospective data analysis. Volunteer women in an academic research environment. PATIENT(S): Six lean and 31 obese subjects, aged 19-33 years. INTERVENTION(S): Patients were treated for 5-6 weeks with NAC at a dose of 1.8 g/day orally. A dose of 3 g/day was arbitrarily chosen for massively obese subjects. Six of 31 obese patients with PCOS were treated with placebo and served as controls. MAIN OUTCOME MEASURE(S): Before and after the treatment period, the hormonal and lipid blood profile and insulin sensitivity, assessed by an hyperinsulinemic euglycemic clamp, were evaluated and an oral glucose tolerance test (OGTT) was performed. RESULT(S): Fasting glucose, fasting insulin, and glucose area under curve (AUC) were unchanged after treatment. Insulin AUC after OGTT was significantly reduced, and the peripheral insulin sensitivity increased after NAC administration, whereas the hepatic insulin extraction was unaffected. The NAC treatment induced a significant fall in T levels and in free androgen index values (P<.05). In analyzing patients according to their insulinemic response to OGTT, normoinsulinemic subjects and placebo-treated patients did not show any modification of the above parameters, whereas a significant improvement was observed in hyperinsulinemic subjects. CONCLUSION(S): NAC may be a new treatment for the improvement of insulin circulating levels and insulin sensitivity in hyperinsulinemic patients with polycystic ovary syndrome.
To determine the metabolic and reproductive effectiveness of rosiglitazone in polycystic ovary syndrome (PCOS). Case report. Academic clinical practice and General Clinical Research Center. PATIENT(S): A 25-year-old woman with PCOS. INTERVENTION(S): Rosiglitazone maleate, 4 mg daily for 5 months until conception. MAIN OUTCOME MEASURE(S): Insulin sensitivity by steady-state plasma glucose technique; serum androgens, progesterone, and hCG; and pelvic ultrasound images. RESULT(S): Rosiglitazone treatment for 5 months improved insulin sensitivity, lowered serum free testosterone, and resulted in spontaneous ovulation and conception. CONCLUSION(S): Rosiglitazone is a promising insulin sensitizer for treatment of PCOS. Clinical trials are warranted.
