Metabolic syndrome, inflammatory and vascular injury markers measured in serum after World Trade Center (WTC) exposures predict abnormal FEV1. We hypothesized that elevated LPA levels predict FEV₁ < LLN.
Nested case-control study of WTC-exposed firefighters. Cases had FEV₁ < LLN. Controls derived from the baseline cohort. Demographics, pulmonary function, serum lipids, LPA and ApoA1 were measured.
LPA and ApoA1 levels were higher in cases than controls and predictive of case status. LPA increased the odds by 13% while ApoA1 increased the odds by 29% of an FEV₁ < LLN in a multivariable model.
Elevated LPA and ApoA1 are predictive of a significantly increased risk of developing an FEV₁ < LLN.
在世贸中心(WTC)暴露后血清中测量的代谢综合征、炎症和血管损伤标志物可预测 FEV1 异常。我们假设升高的 LPA 水平可预测 FEV₁<LLN。
对 WTC 暴露的消防员进行巢式病例对照研究。病例组的 FEV₁<LLN。对照组来源于基线队列。测量了人口统计学、肺功能、血清脂质、LPA 和 ApoA1。
与对照组相比,病例组的 LPA 和 ApoA1 水平更高,且与病例状态相关。在多变量模型中,LPA 使 FEV₁<LLN 的几率增加了 13%,而 ApoA1 使 FEV₁<LLN 的几率增加了 29%。
升高的 LPA 和 ApoA1 可显著预测 FEV₁<LLN 的风险增加。
