RESUMO
BACKGROUND: Polycystic ovary syndrome (PCOS) is a common disorder. PCOS women are at a high risk for insulin resistance and metabolic syndrome (MS). Adiponectin is positively related to insulin sensitivity. It has a preventive role in atherogenesis and MS. The present work was conducted to study the correlation between serum adiponectin levels and clinical characteristics and biochemical parameters in PCOS patients. MATERIALS AND METHODS: A prospective study in 49 newly diagnosed (as per Rotterdam criteria) Indian PCOS women was conducted. PCOS women were clinically examined and investigated for biochemical parameters. RESULTS: The mean serum adiponectin was 12 ± 9.4 µg/mL (range 0.47-45). Hypoadiponectinemia (serum adiponectin <4 µg/mL) was present in 22% patients. Age and adiponectin correlated significantly and inversely (r = -0.42, P = 0.027). Overweight/obese patients had lower mean adiponectin levels than normal weight (11.62 ± 9.5 vs 13.58 ± 9.5, P = 0.56). It was significantly lower in patients with acanthosis nigricans (AN) as compared with those without AN (8.4 ± 5.9 vs 15 ± 11, P = 0.038). Hirsute patients showed lower mean adiponectin levels than nonhirsute (10 ± 7.3 vs 13 ± 10, P = 0.57). A positive, insignificant correlation was observed between serum adiponectin and cholesterol, low-density lipoprotein, follicle stimulating hormone (FSH), thyroid stimulating hormone, levels. A negative insignificant correlation existed between serum adiponectin and luteinizing hormone (LH), LH: FSH ratio, prolactin, dehydroepiandrosterone, testosterone, triglyceride, high-density lipoprotein, fasting blood glucose, fasting insulin, and Homeostasis Model Assessment. CONCLUSION: Hypoadiponectinemia is present in one-fifth of women with PCOS. Adiponectin levels decrease as age advances. Low levels of adiponectin possibly contributes to the development of dermal manifestation (AN) of insulin resistance.
RESUMO
BACKGROUND: Polycystic ovary syndrome (PCOS) is common diagnosis in women presenting with infertility. All the dimensions of PCOS have not been completely explored. Many studies have tried to characterize the exact presentation of the disease. In this study we studied clinical features of PCOS in Indian women to characterize different phenotypes of this syndrome. Prevalence of acanthosis nigricans (AN) as surrogate marker of insulin resistance, obesity, hirsutism and hypothyroidism in PCOS women have been simultaneously studied. MATERIALS AND METHODS: Present work is a non comparative cross-sectional open label study carried out over a period of 18 months in an endocrinology hospital in western Maharashtra, India. RESULTS AND CONCLUSION: Authors conclude that PCOS occurs both in obese and non-obese women; AN and hirsutism occur in equal proportion of patients. AN is correlated with obesity. Hormonal dysfunctions in PCOS manifested together or independently. PCOS women can be sub grouped based on clinical features suggestive of endocrinological malfunctions and can be investigated accordingly for selection of appropriate treatment modalities.
RESUMO
CONTEXT: Rapidly rising prevalence of obesity is alarming. Obesity predisposes to co-morbidities like hypertension, type 2 diabetes mellitus, dyslipidemias, thus substantially rising healthcare expenditure. Lifestyle modifications alone have very limited success, necessitating the addition of pharmacotherapy to it. OBJECTIVE: Present study was carried out to evaluate the efficacy and safety of orlistat in obese patients. MATERIALS AND METHODS: Eighty obese (BMI>30) patients according to inclusion and exclusion criteria were randomized into either of the two groups. Group 1 received orlistat 120 mg three times a day and group 2 received placebo three times a day. Weight, waist circumference, BMI, total cholesterol, triglycerides, HDL, LDL were measured at baseline and then at 8(th), 16(th) and 24(th) week. ADR reported by patients were recorded. For safety evaluation various hematological and biochemical parameters were assessed. Z test was used for analysis of data. RESULTS: Compared to placebo, orlistat caused significant reduction (P<0.05) in weight (4.65 kg vs 2.5 kg; orlistat vs placebo, respectively), BMI (1.91 kg/m(2) vs 0.64 kg/m(2)) and waist circumference (4.84 cm vs 2 cm), cholesterol (10.68 mg vs 6.18 mg) and LDL level (5.87 mg vs 2.33 mg). In the orlistat group, the GI side effects like loose stools, oily stools/spotting, abdominal pain and fecal urgency were observed. CONCLUSION: Orlistat is an effective and well-tolerated antiobesity drug, which can be employed as an adjunct to therapeutic lifestyle changes to achieve and maintain optimal weight.
