白介素-1受体拮抗剂(IL-1Ra)是一种天然的白介素-1β抑制剂,已被证明可以改善2型糖尿病患者的β细胞功能和血糖控制。本研究的目的是在超过10年的随访期间调查IL-1Ra的基线全身水平是否与2型糖尿病的发生有关。研究设计和方法:我们在英国Whitehall II队列中进行了一项巢式病例对照研究(181例和376例年龄、性别和bmi匹配的血糖控制正常的受试者),测量了血清IL-1Ra浓度。结果:IL-1Ra浓度在病例受试者中较高(P = 0.0006),并与2型糖尿病发生率相关(IL-1Ra 1-SD升高的优势比为1.48 [95% CI 1.21-1.80])。在调整多个潜在混杂因素后,这种关联仍然显著,但在调整2小时葡萄糖后减弱。结论:我们的研究结果表明,将发展为2型糖尿病的个体具有复杂的免疫激活特征,包括抗炎细胞因子IL-1Ra的上调。
OBJECTIVE—Interleukin-1 receptor antagonist (IL-1Ra), a natural inhibitor of interleukin-1β, has been shown to improve β-cell function and glycemic control in patients with type 2 diabetes. The aim of this study was to investigate whether baseline systemic levels of IL-1Ra are associated with incident type 2 diabetes during more than 10 years of follow-up. RESEARCH DESIGN AND METHODS—We measured serum IL-1Ra concentrations in a nested case-control study (181 case and 376 age-, sex-, and BMI-matched normoglycemic control subjects) within the Whitehall II cohort (U.K.). RESULTS—IL-1Ra concentrations were higher in case subjects (P = 0.0006) and associated with incident type 2 diabetes (odds ratio for a 1-SD increase of IL-1Ra 1.48 [95% CI 1.21–1.80]). This association remained significant after adjustment for multiple potential confounders but was attenuated by adjusting for 2-h glucose. CONCLUSIONS—Our findings indicate that individuals who will develop type 2 diabetes are characterized by a complex immune activation that also includes upregulation of the anti-inflammatory cytokine IL-1Ra.
