J Periodontal Res:广泛性侵袭性牙周炎的代谢特征分析

2018-10-02 MedSci MedSci原创

广泛侵袭性牙周炎(GAgP)的具体发病机制尚未阐明,并且很少有研究关注GAgP与代谢组学之间的关联。为了阐明代谢特征在GAgP状态中的作用,本研究旨在使用非靶向代谢组学分析方法鉴定GAgP患者与健康对照之间的差异代谢特征。

广泛侵袭性牙周炎(GAgP)的具体发病机制尚未阐明,并且很少有研究关注GAgP与代谢组学之间的关联。为了阐明代谢特征在GAgP状态中的作用,本研究旨在使用非靶向代谢组学分析方法鉴定GAgP患者与健康对照之间的差异代谢特征。

方法:在该横断面研究中,收集健康对照(n = 20)和GAgP(n = 20)患者的血清和龈沟液样品。通过气相色谱 - 质谱法测量样品中生物标记物的相对水平。用主成分分析和正交偏最小二乘判别进行统计分析。使用FiehnLib和NIST数据库定性分析代谢物。记录全口牙周探诊深度和临床附着丧失水平作为牙周病的指标。

结果:在龈沟液样本中定性检测到349种代谢物,在血清样本中检测到200种代谢物。与健康对照相比,GAgP患者血清尿素和异体肌醇水平显着增加。相反,GAgP患者中谷胱甘肽,2,5-二羟基苯甲醛,己二酸和2-脱氧鸟苷水平降低。在龈沟液样本中,GAgP患者的去甲肾上腺素,尿苷,α-生育酚,脱氢抗坏血酸,黄嘌呤,半乳糖,葡萄糖-1-磷酸和核酮糖-5-磷酸水平增加,而胸苷,谷胱甘肽和核糖-5-磷酸盐水平下降。

气相色谱 - 质谱法进行的代谢组学分析是一种有效且极少非侵入性的区分GAgP患者代谢特征的方法。 GAgP患者和健康对照者的血清和龈沟液代谢组学均有显着差异。这些代谢谱在检测GAgP和帮助理解其潜在机制方面具有巨大潜力。
