首发时间:2024-05-09
摘要:目的:通过靶向代谢组学研究中国成年居民血浆己糖神经酰胺(Hexosylceramide, HexCer)(d18:1/22:1)与2型糖尿病(Type 2 diabetes mellitus, T2DM)发病的关联。方法:在中国苏州市工业园区社区人群中开展的巢式病例对照研究。测量了234例T2DM病例和468例对照者的血浆HexCer(d18:1/22:1)。方法:采用条件logistic回归模型探究血浆HexCer(d18:1/22:1)与T2DM发病之间的关系,计算比值比(Odds Ratio, OR)及95% 置信区间(Confidence interval, CI),并拟合限制性立方样条(Restricted Cubic Spline, RCS)模型评估剂量-反应关系。结果:多因素调整后,HexCer(d18:1/22:1)位于第四分位组的人群T2DM的风险显著增加,OR(95% CI)为1.81 (1.12, 2.92),与HexCer(d18:1/22:1)正常组相比,HexCer(d18:1/22:1)升高组发生T2DM的风险显著增加(OR 1.62,95% CI:1.11, 2.36);此外,血浆HexCer(d18:1/22:1)的水平每增加一个对数转换标准差,T2DM的发病风险增加28%。RCS模型分析显示,血浆HexCer(d18:1/22:1)与T2DM的发病风险存在线性剂量反应关系(P线性<0.05)。结论:研究揭示了中国成年人群中HexCer(d18:1/22:1)与T2DM之间的关联性,高水平HexCer(d18:1/22:1)可增加T2DM的发病风险,且存在线性剂量-反应关系,HexCer(d18:1/22:1)可能是T2DM发病的潜在生物标志物。

Association of plasma hexose ceramide (d18:1/22:1) with the development of type 2 diabetes mellitus
Abstract:OBJECTIVE: To investigate the association between plasma Hexosylceramide (HexCer) (d18:1/22:1) and the development of Type 2 diabetes mellitus (T2DM) in Chinese adult residents by targeted metabolomics. METHODS: This was a nested case-control study conducted in a community-based population in the Suzhou Industrial Park, China. Plasma HexCer (d18:1/22:1) was measured in 234 T2DM cases and 468 controls. Conditional logistic regression models were used to explore the association between plasma HexCer (d18:1/22:1) and the onset of T2DM, and Odds Ratio (OR) and 95% Confidence interval (CI) were calculated, and Restricted Cubic Spline (RCS) model was fitted to assess the dose-response relationship. RESULTS: After multivariate adjustment, the risk of T2DM in the fourth quartile of HexCer(d18:1/22:1) was significantly increased, with OR (95%CI) of 1.81 (1.12, 2.92). Compared with the normal HexCer(d18:1/22:1) group, the risk of T2DM in the elevated HexCer(d18:1/22:1) group was significantly increased (OR 1.62, 95%CI :1.11, 2.36). In addition, the risk of T2DM increased by 28% for each increase in the level of plasma HexCer(d18:1/22:1) by log-transformed standard deviation. RCS model analysis showed that there was a linear dose-response relationship between plasma HexCer(d18:1/22:1) and the risk of T2DM (P linear <0.05).CONCLUSION: The study revealed an association between HexCer(d18:1/22:1) and T2DM in the Chinese adult population, high levels of HexCer(d18:1/22:1) increased the risk of developing T2DM, and there was a linear dose-response relationship, and HexCer(d18:1/22:1) may be a potential biomarker of T2DM pathogenesis.
