ABSTRACT
A síndrome de hiperestímulo ovariano (SHO) pode ocorrer de forma espontânea na gestação ou durante indução da ovulação para fertilização in vitro. Com o objetivo de identificar fatores clínicos e hormonais de risco para a SHO iatrogênica e analisar o papel das variantes alélicas do FSHR na sua etiologia, estudamos 29 pacientes com SHO iatrogênica moderada e grave. Idade < 33,5 anos, FSH basal < 5,2 UI/L e resposta de estradiol > 1757 pg/mL durante a estimulação ovariana atuaram como preditores independentes do risco de desenvolvimento da SHO iatrogênica, sendo a associação dos três fatores capaz de predizer a síndrome com acurácia de 7 por cento. Não foram encontradas mutações nas 29 pacientes com SHO iatrogênica. Entretanto, o alelo Asn680 do polimorfismo Ser680Asn se associou às formas mais graves da SHO iatrogênica / Ovarian hyperstimulation syndrome (OHSS) can occur spontaneously during early pregnancy or as an iatrogenic complication in assisted reproductive medicine. The aim of this study was to identify clinical and hormonal risk factors for iatrogenic OHHS and to evaluate the role of allelic variants of the FSHR in the etiology of this syndrome. We studied 29 patients with moderate and severe iatrogenic OHHS. Age < 33.5 y, basal FSH < 5.2 U/L and estradiol response during ovarian stimulation > 1757 pg/mL were independent risk factors for iatrogenic OHSS and these three factors in association were able to predict the syndrome with accuracy of 78 per cent. We did not find mutations in any patient studied. However, there was a predominance of the Asn680 allele of Ser680Asn polymorphism in patients with the most severe forms of the syndrome...
