摘要:

目的 分析幽门螺杆菌(HP)感染对脑梗死后血管性痴呆(CI-VD)患者血清同型半胱氨酸(Hcy)水平和认知功能的影响。方法 选取2020年2月—2022年8月开封市中心医院90例CI-VD患者(研究组),以同期开封市中心医院90例非CI-VD患者为对照组。比较2组患者一般资料、HP感染率、血清Hcy水平,以及简易智能精神状态检查量表(MMSE)评分差异。比较研究组HP阳性患者和HP阴性患者血清Hcy水平和MMSE评分差异。采用Logistic回归分析评价CI-VD患者HP感染与血清Hcy水平和MMSE评分的关系。结果 研究组HP感染率高于对照组,血清Hcy水平高于对照组,MMSE评分低于对照组(P<0.001)。研究组HP阳性患者血清Hcy水平较阴性患者高,MMSE评分较阴性患者低(P<0.001)。HP感染与Hcy水平呈正相关(r=0.382,P<0.001),与MMSE评分呈负相关(r=-0.396,P<0.001)。结论 HP感染与CI-VD患者血清Hcy水平和认知功能存在一定的相关性,血清Hcy水平和MMSE评分可用于评估患者病情。

Abstract:

Objective To investigate the effect of Helicobacter pylori(HP)infection on serum homocysteine (Hcy) level and cognitive function in patients with vascular dementia after cerebral infarction(CI-VD). Methods Ninety patients with CI-VD who were hospitalized from February 2020 to August 2022 were enrolled as study group,and another 90 patients without CI-VD were enrolled as control group. The general information,HP infection rate,serum Hcy level and mini-mental state examination(MMSE)scores of the 2 groups were compared. The study group was classified into positive infection group and negative infection group. Serum Hcy level and MMSE score were compared between positive and negative infection groups. The relationship between HP infection and serum Hcy level and MMSE score in patients with vascular dementia after cerebral infarction was analyzed. Results The infection rate of HP in study group was higher than that in control group,serum Hcy level was higher than that in control group,and the MMSE score was lower than that in control group(P<0.001). The serum Hcy level of patients with HP positive infection in study group was higher than that of patients with negative infection,and the MMSE score was lower than that of patients with negative infection(P<0.001). Serum HP infection was positively correlated with Hcy level(r=0.382,P<0.001),and it was negatively correlated with MMSE score(r=-0.396,P<0.001). Conclusions There is a correlation between HP infection and serum Hcy level and cognitive function in patients with vascular dementia after cerebral infarction. Serum Hcy level and MMSE score can be used to assess patients' condition.
