ABSTRACT
Patients with polycystic ovary syndrome (PCOS) present a higher risk for abnormalities of glucose metabolism (AGM). For to study this in our population, we submitted 85 patients, with body mass index (BMI) of 28.5 ± 6.6 kg/m² and aged 25.5 ± 5.4 years old, to an oral glucose tolerance test (OGTT), and assessed the impact of BMI on the prevalence of impaired glucose tolerance (IGT) and of diabetes mellitus (DM). The states of glucose tolerance were classified considering fasting plasma glucose (FPG) according to the American Diabetes Association (ADA) criterion and plasma glucose at 120 minutes according to the Word Health Organization (WHO) criterion. According to the ADA criteria, 83.5 percent classified as normal and 16.5 percent as with AGM, with 15.3 percent presenting impaired fasting glucose and 1.2 percent DM, while according to the WHO criteria, 68.2 percent were classified as normal and 31.8 percent as with AGM, with 27.0 percent of them presenting IGT and 4.8 percent DM. Seventy-three percent of PCOS patients with IGT by WHO criterion had normal FPG by ADA criterion. The prevalence of AGM for both criteria increased with the body mass index. In conclusion, we found a higher prevalence of AGM in PCOS patients than that found in the general population, being the highest in obese patients. Glycemia at 120 minutes on the OGTT identified more patients with AGM than fasting glycemia. We recommended that the assessment of AGM must be done by the OGTT in all patients with PCOS.
RESUMO
Pacientes com a síndrome dos ovários policísticos (SOP) têm um risco maior para desenvolver anormalidades do metabolismo da glicose (AMG). Para avaliarmos a prevalência dessas anormalidades na nossa população, submetemos 85 pacientes, com índice de massa corporal (IMC) de 28,5 ± 6,6 kg/m² e média etária de 25,5 ± 5,4 anos, a teste de tolerância oral à glicose (TTOG). Os estados de tolerância à glicose foram classificados considerando a glicemia de jejum (GJ; American Diabetes Association - ADA) e glicemia aos 120 minutos (G120; Organização Mundial de Saúde - OMS). De acordo com a ADA, 83,5 por cento das pacientes foram normais e 16,5 por cento com AMG, com 15,3 por cento apresentando glicemia de jejum imprópria e 1,2 por cento diabetes mellitus (DM). De acordo com a OMS, 68,2 por cento foram normais e 31,8 por cento com AMG, com 27,0 por cento apresentando intolerância à glicose (IG) e 4,8 por cento DM. Observamos que 73 por cento das pacientes com IG pelos critérios da OMS apresentavam GJ normal pelos critérios da ADA. A prevalência de AMG para ambos os critérios foi maior entre as pacientes com IMC mais elevado. Conclusão:
encontramos maior prevalência de AMG nas pacientes com a SOP do que na população geral, sendo mais elevada entre as pacientes obesas. Além disso, a G120 no TTOG identificou maior número de pacientes com AMG do que a GJ. Assim, recomendamos avaliação de AMG através do TTOG para todas as pacientes portadoras da SOP.
