[Polycystic ovarian disease: clinical and biochemical expression]

The policystic ovary (PO) results from a systemic hormonal dysfunction, characterized by hyperandrogenemia, insulin resistance and anovulation.

Assessment was made of clinical and biochemical features of patients with PO.

A retrospective analysis of 211 clinical of charts of patients with ultrasonographic diagnosis of PO seen at the Hospital Juárez de México from 1996 to 2000 was performed. Evaluation was made of body mass index (BMI), waist hip index (WHI), Ferriman index, acanthosis nigricans, lipid and hormonal profile.

Of patients studied (n = 211) 64% had infertility and abnormal menses associated to PO, while the rest was normal. Both groups (PO and normal), were similar in age and distribution as well as family back grown for diabetes mellitus, hypertensive disease and obesity. The clinical manifestations observed on patients with PO were infertility 79.16%, anovulation 68.42%, hirsutism 66.9% obesity (66.9%). Biochemical findings in PO patients vs normal patients were: hyperandrogenism (86.73% vs 71.4%), insulin resistance (60.46% vs 37.5%), dislipidemic (56.41% vs 31.5%), LH/FSH ratio > 2 (19.51% vs 10.51%). Regarding sensitivity and specificity for clinical and biochemical findings ranged from 0.64 at 0.90, minimum value had infertility and maximum anovulation; specificity (interval 0.31 to the 0.71) minor corresponded to hyperprolactinemia and higher to infertility. The estimated risk factor (OR) for the population studied exhibited anovulation (OR, 7; 95% IC, 1.79-32.92); infertility (OR, 4.51; 95% IC, 2.03-10.13); insulin resistance (OR, 3; 95% IC, 0.82-8.16); hyperandrogenism (OR, 2.61; 95% IC, 1.02-6.69); and obesity (OR, 2.16; 95% IC, 1.17-4). We concluded that population with PO has a higher risk of infertility, anovulation, obesity, hyperandrogenism, dyslipidemia, insulin resistance and abnormal menses.
