新诊断2型糖尿病患者血清白细胞介素6和白细胞介素18水平的研究

目的 探讨新诊断2型糖尿病患者血清白细胞介素6(IL-6)、白细胞介素18(IL-18)水平的变化及意义.方法 选择50例新诊断2型糖尿病患者(2型糖尿病组)和40例健康体检者(对照组),测定两组空腹血清IL-6、IL-18水平,分别检测空腹血糖、血脂、空腹胰岛索,同时计算体重指数、腰臀比,采用稳态模型公式计算胰岛素抵抗指数(HOMA-IR)及胰岛β细胞功能指数(HOMA-β).结果 2型糖尿病组患者血清IL-6、IL-18水平较对照组明显升高(2.56±1.09)ng/L比(1.81±0.80)ng/L和(5.38±0.91)ng/L比(4.62±0.59)ng/L](P<0.01).经相关性分析:IL-6水平与糖化血红蛋白呈正相关.IL-18水平与体重指数和腰臀比呈正相关,且IL-6与IL-18呈正相关.回归分析结果表明血清IL-6、IL-18均能较好地预测胰岛素抵抗程度.结论 炎性因子IL-6、IL-18可能参与2型糖尿病的发生,血清IL-6、IL-18水平升高,可间接反映胰岛素抵抗程度.

Levels of serum interleukin-6 and interlenkin-18 in newly diagnosed type 2 diabetes mellitus

Objective To explore the levels of serum interleukin-6 and interleukin-18 in newly diagnosed type 2 diabetes mellitus (T2DM) and investigate their roles. Methods The serum interleukin-6 and interleukin-18 levels were detected in 50 newly, diagnosed T2DM patients (T2DM group) and 40 normal subjects (control group). Fasting blood glucose, fasting insulin, blood lipid, body mass index (BMI) and waist/hip ratio (WHR) were measured. HOMA-IR and HOMA-β were calculated. Results The serum interleukin-6 and interleukin-18 levels in T2DM group were significantly higher than those in control group (2.56 ± 1.09) ng/L vs (1.81±0.80) ng/L, (5.38±0.91) ng/L vs (4.62±0.59)ng/L] (P <0.01).Interleukin-6 level was positively correlated with HbA_1c,while interleukin-18 level was positively correlated with BMI and WHR. Interleukin-6 and interleukin-18 levels were positively correlated. Interleukin-6 and interhukin-18 could predicted the insulin resistance. Conclusion Interleukin-6 and interleukin-18 take part in the development of T2DM, and can be related to the insulin resistance.
