To evaluate the potential association between different inflammatory markers and insulin resistance (IR), as well as insulin-resistance syndrome (IRS) in a large, population-based study of older, nondiabetic persons.
Cross-sectional study.
Outpatient clinic in Greve in Chianti and Bagno a Ripoli (Italy).
One thousand one hundred forty-six nondiabetic subjects ranging in age from 22 to 104.
Anthropometric measurements; plasma fasting levels of glucose, insulin, and cholesterol (total, high-density lipoprotein, low-density lipoprotein); homeostasis model assessment to estimate degree of insulin resistance; tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), soluble IL-6 receptor (sIL-6R), interleukin receptor antagonist (IL-1ra), and C-reactive protein (CRP) plasma concentrations; diastolic, systolic, and mean arterial blood pressure; and echo-color-Doppler duplex scanning examination of carotid arteries.
Insulin resistance correlated with age (r=0.102; P<.001) and plasma levels of TNF-alpha (r=0.082; P=.007), IL-1ra (r=0.147; P<.001), IL-6 (r=0.133; P<.001), sIL-6R (r=-0.156; P<.001), and CRP (r=0.83; P<.001). Subjects in the upper tertile of IR degree were older and had higher serum levels of TNF-alpha, IL-1ra, and IL-6 and lower levels of sIL-6R than subjects in the lowest tertile. Independent of age, sex, body mass index, waist-to-hip ratio, triglycerides, drug intake, diastolic blood pressure, smoking habit, and carotid atherosclerotic plaques, higher IL-6 (t=2.987; P=.003) serum concentrations were associated with higher IR, whereas sIL-6R levels (t=-5.651; P<.001) were associated with lower IR. Furthermore, IL-1ra concentrations (t=2.448; P=.015) were associated with IRS, and higher sIL-6R plasma levels continued to correlate negatively with IRS.
Different inflammatory markers are associated with a diverse effect on IR and IRS in elderly nondiabetic subjects.
在一项针对老年非糖尿病患者的大型人群研究中，评估不同炎症标志物与胰岛素抵抗（IR）以及胰岛素抵抗综合征（IRS）之间的潜在关联。
横断面研究。
意大利基安蒂地区格雷韦和巴尼奥阿里波利的门诊诊所。
1146名年龄在22岁至104岁之间的非糖尿病受试者。
人体测量指标；空腹血糖、胰岛素和胆固醇（总胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇）的血浆水平；采用稳态模型评估来估计胰岛素抵抗程度；肿瘤坏死因子α（TNF-α）、白细胞介素6（IL-6）、可溶性IL-6受体（sIL-6R）、白细胞介素受体拮抗剂（IL-1ra）和C反应蛋白（CRP）的血浆浓度；舒张压、收缩压和平均动脉压；以及颈动脉的超声彩色多普勒双功扫描检查。
胰岛素抵抗与年龄（r = 0.10²；P <.001）、TNF-α血浆水平（r = 0.082；P =.007）、IL-1ra（r = 0.147；P <.001）、IL-6（r = 0.133；P <.001）、sIL-6R（r = -0.156；P <.001）和CRP（r = 0.83；P <.001）相关。IR程度处于最高三分位数的受试者比最低三分位数的受试者年龄更大，TNF-α、IL-1ra和IL-6的血清水平更高，而sIL-6R水平更低。独立于年龄、性别、体重指数、腰臀比、甘油三酯、药物摄入、舒张压、吸烟习惯和颈动脉粥样硬化斑块，较高水平IL-6（t = 2.987；P =.003）的血清浓度与较高的IR相关，而sIL-6R水平（t = -5.651；P <.001）与较低的IR相关。此外，IL-1ra浓度（t = 2.448；P =.015）与IRS相关，较高的sIL-6R血浆水平继续与IRS呈负相关。
不同的炎症标志物对老年非糖尿病受试者的IR和IRS有不同的影响。
