多囊卵巢综合征患者血清内脂素和高敏C反应蛋白水平的测定与临床意义

目的探讨多囊性卵巢综合征（PCOS）患者血清中内脂素和高敏C反应蛋白（Hs—CRP）的水平及其临床意义。方法对90例PCOS患者及30例正常者（正常对照组）分别采用酶联免疫吸附试验（ELISA）法检测血清内脂素水平，采用免疫比浊法检测血清中Hs—CRP水平；同时根据体重指数（BMI）将PCOS患者分为肥胖PCOS组（BMI≥25，48例）和非肥胖PCOS组（BMI〈25，42例）。结果①肥胖及非肥胖PCOS患者血清中内脂素和Hs—CRP水平分别为（37±6）与（28±5）μg/L、（4．9±0．6）与（2．4±0．5）mg／L，均明显高于正常对照组的（17±4）μg／L与（2．0±0．5）mg／L（t值分别为11．35，8．46，10．43，8．25，均P〈0．05），肥胖PCOS患者血清中内脂素和Hs—CRP水平均明显高于非肥胖PCOS患者（t值分别为7．74，6．38，均P〈0．05）；②Pearson相关分析显示，内脂素与Hs—CRP、BMI、胰岛素抵抗指数（HOMA—IR）呈正相关（P〈0．05）；Hs—CRP与BMI、HOMA—IR呈正相关（P〈0．05）。结论PCOS患者体内可能存在慢性炎症，并可能是导致血清内脂素和Hs—CRP水平升高的原因。

Determination of serum levels of visfatin and high-sensitivity C-reactive protein in patients with polycystic ovary syndrome

Objective To explore serum levels of visfatin and high-sensitivity C-reactive protein (Hs-CRP) in patients with polycystic ovary syndrome (PCOS), as well as their clinical significance. Methods Ninety patients with PCOS and 30 ovulating healthy women with body mass index (BMI) less than 25 as controls were recruited. PCOS patients were divided to two groups, 48 in obese group with BMI≥ 25 and 42 in non-obese group with BMI<25. Serum level of visfatin was measured by enzyme-linked immunosorbent assay (ELISA) and that of Hs-CRP was assayed by immunoturbidimetry in all participants. Oral glucose tolerance test (OGTT) and insulin sensitivity were assessed in PCOS patients only. Results ①Obese and non-obese patients with PCOS beth presented markedly higher serum levels of visfatin and Hs-CRP than those in controls (t=11.35, 8.46, 10.43 and 8.25, respectively, P<0.05), and levels of visfatin and Hs-CRP were higher in obese group than those in non-obese group (t=7.74 and 6.38, respectively, P< 0.05 ). ②Univariate analysis revealed that serum levels of visfatin and Hs-CRP positively correlated with BMI and homeostasis model assessment insulin resistance, respectively (P<0.05) and serum level of visfatin positively correlated with that of Hs-CRP (P<0.05). Conclusions Chronic inflammation possibly exists in patients with PCOS, which may cause their serum visfatin and Hs-CRP levels increased.
