摘要
背景:动脉粥样硬化伴随着低级别炎症反应。假设:使用红细胞聚集性作为生物标志物,排除明显健康个体中存在的低级别炎症反应。方法:采用简单的载玻片法和图像分析方法定量测定红细胞黏附/聚集性。结果:我们纳入了121名表面健康的个体,发现红细胞黏附/聚集程度与高敏CRP (r = 0.6, P < 0.001)、红细胞沉降率(r = 0.5, P < 0.0001)或纤维蛋白原(r = 0.5, P < 0.0001)的浓度有显著相关性。通过使用红细胞黏附性/聚集性测试的某些截止点,我们可以定义具有非常低级别炎症反应的个体。结论:通过使用这种廉价和快速的评估,我们可以清楚地区分炎症反应非常低的个体和炎症反应更强烈的个体。这种生物标记物应该被进一步评估,作为一种可能的筛选试验,用于大量明显健康的人群,在这些人群中,低度炎症的检测可能有助于指导适当的生活方式改变和治疗干预。
A simple biomarker to exclude the presence of low grade inflammation in apparently healthy individuals.
Background: Atherosclerosis is accompanied by a low grade inflammatory response.
Hypothesis: To use erythrocyte aggregability as a biomarker to exclude the presence of low grade inflammatory response in apparently healthy individuals.
Methods: The adhesiveness/aggregation of red blood cells was quantitated by using a simple slide test and image analysis.
Results: We included 121 apparently healthy individuals and found a significant correlation between the degree of erythrocyte adhesiveness/aggregation and either the concentration of high sensitive CRP (r = 0.6, P < 0.001), erythrocyte sedimentation rate (r = 0.5, P < 0.0001) or fibrinogen (r = 0.5, P < 0.0001). By using certain cutoff points for the erythrocyte adhesiveness/aggregation test we could define individuals with a very low grade inflammatory response.
Conclusions: By using this inexpensive and rapid assessment, we could clearly discriminate between individuals with a very low inflammatory response and those with a more intense one. This biomarker should be further evaluated as a possible screening test for use in large populations of apparently healthy individuals in whom the detection of low grade inflammation might contribute to guiding appropriate lifestyle modifications and therapeutic interventions.
