Resumo
A síndrome dos ovários policísticos (SOP) afeta 5 a 8% das mulheres no menacme e é caracterizada pela anovulação crônica e hiperandrogenismo. A obesidade central e a resistência insulínica (RI) são freqüentes na SOP e desempenham um papel fundamental na etiopatogenia da síndrome metabólica (SM). O hiperandrogenismo tem sido questionado como um fator importante no desenvolvimento da SM em mulheres com SOP. Verificar se o hiperandrogenismo influencia no desenvolvimento de síndrome metabólica em pacientes com SOP. Foram avaliados retrospectivamente os dados clínicos, bioquímicos e ultrassonográficos de 180 mulheres com SOP diagnosticadas pelos critérios de Rotterdam e de 70 mulheres com obesidade simples. As pacientes com SOP foram classificadas de acordo com o índice de massa corporal (IMC) em SOP não obesas e SOP obesas. As pacientes obesas simples não apresentaram hiperandrogenismo clínico nem bioquímico. O índice de sensibilidade à insulínica (ISI) foi avaliado pelo HOMA-IR e ISI de Matsuda e DeFronzo. A SM foi diagnosticada pelos critérios do NCEP-ATP III com modificações sugeridas pelo consenso de Rotterdam. A média de idade das pacientes foi de 27,3 + 4,7 no grupo das pacientes SOP não obesas; 28,8 + 5,0 nas SOP obesas e 27,4 + 5,2 nas obesas simples (p=0, 0773), e o IMC foi de 25,1+3,0 kg/m2; 37,0+ 5,5 kg/m2 e 36,0+ 4,2 kg/m2 respectivamente (p<0, 001). A prevalência de RI e SM não diferiu entre as pacientes obesas com e sem SOP e foi significativamente maior do que nas SOP não obesas (p<0, 001). Entretanto a prevalência de SM foi maior nas SOP obesas com hiperandrogenismo...
Polycystic ovary syndrome (PCOS) affects 5-8% of women at menacme and is characterized by chronic anovulation and hyperandrogenism. Central obesity and insulin resistance (IR) are frequent in PCOS and play a leading role in the etiopathogeny of metabolic syndrome (MS). Hyperandrogenism has been suggested as an important factor in the development of MS in women with PCOS. To determine whether hyperandrogenism influences the development of metabolic syndrome in patients with PCOS. Clinical, biochemical and ultrasonographic data on 180 women with PCOS, as diagnosed by the Rotterdam criteria, and 70 women with simple obesity were retrospectively analyzed. According to body mass index, PCOS patients were classified as nonobese with PCOS and obese with PCOS. No clinical or biochemical hyperandrogenism was observed in patients with simple obesity. Insulin sensitivity indices (ISI) were assessed as proposed by HOMA-IR and ISI (Matsuda and De Fronzo). MS was diagnosed based on NCEP-ATP III criteria with modifications suggested by the Rotterdam consensus. Mean age was 27.3 + 4.7 among non-obese patients with PCOS, 28.8 + 5.0 in obese patients with POS, and 27.4 + 5.2 in those with simple obesity (p=0.0773), while BMI was 25.1+3.0 kg/m2, 37.0+ 5.5 kg/m2 and 36.0+ 4.2 kg/m2, respectively (p<0.001). The prevalence of IR and MS did not differ between obese patients with and without PCOS, and was significantly higher in these patients than in non-obese women with PCOS (p<0.001). The prevalence of MS, however, was higher... (Complete abstract click electronic access below)
