代谢综合征与血清IL-18、IL-6关系的研究

目的 探讨代谢综合征(MS)患者各组分与血清IL-18、IL-6水平的关系.方法 选择MS患者83例,正常健康对照85例,分别测量血压、腰围、臀围,测定空腹血糖(FBG)、空腹血胰岛素(FINS),计算胰岛素敏感指数HOMA-β、HOMA-IR,分别检测IL-6、IL-18、血脂等指标,并对结果进行分析.结果代谢综合征组的HOMA-β较正常健康对照组明显下降(P<0.05),HOMA-IR、IL-6、IL-18等指标等明显升高(P<0.05).多元线性回归显示:代谢综合征患者组IL-18与FBG、FINS、TG水平及HOMA-IR呈正相关(r=0.31,0.44,0.48,0.35,P<0.05)与HOMA-β呈负相关(r=-0.474,P<0.05).结论 代谢综合征患者存在明显的胰岛素抵抗和IL-6、IL-18水平的异常;IL-18水平的异常与胰岛素抵抗密切相关;炎症反应可能在代谢综合征患者胰岛素抵抗的发生中起了重要的作用.

The study of interleukin-6 and interleukin-18 concentration in patients with metabolic syndrome

Objective To investigate the association of serum interleukin-6 and interleukin-18 concentration in patients with meta-bolic syndrome (MS), and explore the role of inflammtory markers in these patients. Methods 83 patients with MS were enrolled into study group, among of them, 47 were male and 36 were female, their average was 48.95±10. 17 years. The control group was made of 85 normal volunteers. The levels of fasting blood glucose (FBG), fasting insulin, plasma lipids, interleukin-6 and interleukin-18 were meas-ured in all the patients and normal subjects. The insulin sensitive index was calculated. The levels of the fasting blood inflammatory markers were compared between the two groups. Results Compared with the control group, the HOMA-βof the MS group was significantly de-creased, but the levels of IL-18 and IL-6 were significantly increased. The serum IL-18 levels were positive correlated with FPG, FINS, TG, HOMA-IR, IL-6. Conclusion There are IR and abnormal serum level of IL-18 and IL-6 in patients with MS. It has an intimate association between abnormal serum IL-18 and IR. The inflammatory reaction may play an important role in the development of IR in patients with MS.
