JGH:持续性感染幽门螺杆菌3年以上会导致血清同型半胱氨酸浓度升高

2021-07-03 MedSci原创 MedSci原创

同型半胱氨酸是人体内的一种含硫氨基酸。身体内正常浓度的同型半管氨酸是我们机体维持正常运转所必须的一种物质,是蛋氨酸和半胱氨酸的中间代谢产物。

      同型半胱氨酸是人体内的一种含硫氨基酸。身体内正常浓度的同型半管氨酸是我们机体维持正常运转所必须的一种物质,是蛋氨酸和半胱氨酸的中间代谢产物。我们人体获取同型半胱氨酸的唯一途径是摄入含有蛋氨酸的食物,而动物蛋白中含有较高的蛋氨酸。同型半胱氨酸不仅可以预测心脑血管疾病,还可以预测抑郁症、早老性痴呆、流产、出生缺陷以及其他的情况。研究发现,同型半胱氨酸会损伤动脉、脑甚至是DNA, 它至少与50种以上的疾病相关联。幽门螺杆菌(H. pylori)感染与同型半胱氨酸之间的关系尚不清楚。对此,本项研究对一部分中国人群进行了幽门螺杆菌与血清同型半胱氨酸之间相关性的影响。

 

       在本项研究中,共有 21184 名18岁以上的人接受了13C/ 14C 尿素酶呼气试验(13C/ 14 C-UBT)和血液同型半胱氨酸的检查,5042 名患者的随访时间间隔大于 6 个月。同型半胱氨酸水平根据中国专家共识分为高中低。

 

       在本项研究中幽门螺杆菌检测水平为正常水平,轻度级别,中等水平,和严重程度感染分别为40.9%,43.8%,45.8%和46.6%(P=.0001)。H. pylori感染会增加高半胱氨酸浓度的风险(OR = 1.406,P=.0001)。病例对照研究中,持续阴性、新感染、持续感染和根除感染率分别为43.6%、11.2%、22.9%和22.3%。血清同型半胱氨酸水平变化的百分比在不同H. pylori感染状态之间差异显着。持续感染亚组的平均同型半胱氨酸变化值高于持续阴性亚组(P=.004)和根除感染的亚组(P=.034)。

 

      本项研究证实,幽门螺杆菌感染与患者的血清同型半胱氨酸有一定关系,持续感染会导致后者升高。
