Foram avaliados, além do padrão menstrual e do hiperandrogenismo, o perfil hormonal (FSH, LH, 17 beta-estradiol, testosterona total e livre, 17 hidroxiprogesterona, sulfato de dehidroepiandrosterona), os níveis séricos de IGF-1, IGFBP-3, SHBG (globulina ligadora de hormônios sexuais), as repercussões no risco cardiovascular (circunferência abdominal, HDL-colesterol, triglicérides, pressão arterial sistêmica, glicemia e insulina), o fluxo sangüíneo dos ovários pela ultrassonografia transvaginal e os aspectos histomorfológicos do endométrio após o tratamento. O estudo foi prospectivo, randomizado, duplo-cego e controlado com placebo. Foram incluídas 33 pacientes, subdivididas em dois grupos: 1) Grupo Placebo (XZ), com 17 pacientes e 2) Grupo Rosiglitazona (ZX), com 16 pacientes, que fizeram uso de uma cápsula de 4 mg, por via oral, duas vezes ao dia, por 12 semanas. Concluímos que o tratamento com rosiglitazona por três meses determinou: 1) melhora do padrão menstrual e dos sintomas e sinais clínicos relacionados com o hiperandrogenismo; 2) redução dos níveis de testosterona livre, androstenediona e do fator de crescimento insulinóide tipo 1; 3) elevação dos índices da proteína carreadora de esteróides sexuais (SHBG); 4) melhora da resistência insulínica, evidenciada pela sobrecarga glicêmica de 2 horas; 5) redução do número de mulheres com síndrome metabólica e 6) predomínio de endométrio secretor. Não houve variação significante do volume e do fluxo ovariano após o tratamento com rosiglitazona. Sugere-se que a rosiglitazona constitui alternativa para a correção da resistência insulínica, diminuindo a ocorrência de síndrome metabólica. Além disso, melhora o padrão menstrual e o hiperandrogenismo. / The objectives of the present study are to evaluate the clinical, endocrine and metabolic effects of the rosiglitazone in patients with polycystic ovarian syndrome before and after twelve weeks of treatment. It was be evaluated, besides menstrual pattern and the hyperandrogenism, the hormonal profile (FSH, LH, 17 B-estradiol, total and free testosterone, 17 hydroxiprogesterone, dehudroepiandrosterone sulphate) and the seric levels of IGF-1, IGFBP-3, SHBG (globulin that links sexual hormones); examine the repercussions of cardiovascular risk (abdominal circumference, HDLs cholesterol, triglycerides, systemic arterial pressure, glycemy and insulin); verify thru transvaginal ultrasonography, the ovary blood flow and the endometrial histomorphologic aspects after treatment. The study was prospective, randomized, doubleblinded, using placebo as control. 33 patients were included and divided in two groups 1) Placebo Group (XZ), with 17 patients and 2) Rosiglitazone Group (ZX), with 16 patients, who used a capsule with 4mg, oral way, twice a day, for 12 weeks. We concluded that the treatment with rosiglitazone during three months determined: 1) improved the menstrual pattern and the symptoms and clinic signs related with hyperandrogenism; 2) a decrease in androstenedione, free testosterone and type 1 growth factor insulinoid values; 3) increase of the sexual steroids carry protein (SHBG) index; 4) improvement of the insulinic resistance, shown by the 2 hours glycemic overload; 5) a number reduction of women with metabolic syndrome and 6) the endometrium secrecy pattern got predominant. No significance variation in ovarian volume and flow were found after treatment with rosiglitazone. It’s suggested that rosiglitazone is a alternative way to correct insulinic resistance, decreasing the occurrence of the metabolic syndrome. Besides, it increases the menstrual pattern and hyperandrogenism. / TEDE / BV UNIFESP: Teses e dissertações
