摘要:

目的·观察血清Th17/Treg水平的变化对阿尔茨海默病与牙周炎的影响。方法·纳入2020年6月—2021年12月就诊于上海交通大学医学院附属精神卫生中心老年科共18位伴阿尔茨海默病的牙周炎患者与同时期就诊于上海交通大学医学院附属第九人民医院共15位认知功能正常的牙周炎患者,检查并记录患者探诊深度(probing depth,PD)、附着丧失(clinical attachment loss,CAL)及探诊出血位点比例(percentage of bleeding on probing,BOP%)。使用酶联免疫吸附法检测血清中Th17相关细胞因子白细胞介素-6(interleukin-6,IL-6)、IL-17、IL-22及Treg相关细胞因子IL-4、IL-10、转化生长因子-β(transforming growth factor-β,TGF-β)水平。采用样本独立t检验比较2组牙周指标与细胞因子水平的差异,P<0.05表示差异具有统计学意义。结果·伴阿尔茨海默病的牙周炎患者PD(P=0.021)、CAL(P=0.023)及BOP%(P=0.018)均显著高于认知功能正常的牙周炎患者。伴阿尔茨海默病的牙周炎患者血清IL-6(P=0.010)、IL-17(P=0.022)、IL-22(P=0.031)水平均显著高于认知功能正常的牙周炎患者;同时,组中IL-4(P=0.002)及IL-10(P=0.049)、TGF-β(P=0.006)水平相较于认知功能正常的牙周炎患者显著降低。结论·伴阿尔茨海默病牙周炎患者的牙周状况比认知功能正常的牙周炎患者差,Th17相关促炎细胞因子升高,而Treg相关抗炎因子降低,说明牙周炎可能通过介导Th17/Treg相关的慢性炎症反应影响阿尔茨海默病的发生发展。

Abstract:

Objective ·To observe the role of serum Th17/Treg levels in the correlation between Alzheimer′s disease and periodontitis. Methods ·Eighteen periodontitis patients with Alzheimer′s disease who visited the Department of Geriatric, Shanghai Mental Health Center, Shanghai Jiao Tong University School of Medicine, and 15 periodontitis patients with normal cognitive function who visited the Department of Periodontology, Shanghai Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine from June 2020 to December 2021, were enrolled in this study. Probing depth (PD), clinical attachment loss (CAL) and percentage of bleeding on probing (BOP%) were examined and recorded. Serum levels of Th17-related cytokines interleukin-6 (IL-6), IL-17, and IL-22, Treg-related cytokines IL-4 and IL-10, and transforming growth factor-β (TGF-β) were measured by ELISA. The differences of periodontal status and cytokine levels were compared by using t-test. The difference was statistically significant when P<0.05. Results ·The PD (P=0.021), CAL (P=0.018) and BOP% (P=0.018) were significantly higher in the periodontitis patients with Alzheimer′s disease than those in periodontitis patients with normal cognitive function. The serum IL-6 (P=0.010), IL-17 (P=0.022) and IL-22 (P=0.031) levels were significantly higher in the periodontitis patients with Alzheimer′s disease than those in periodontitis patients with normal cognitive function, while the levels of IL-10 (P=0.049), IL-4 (P=0.002) and TGF-β (P=0.006) in the periodontitis patients with Alzheimer′s disease were significantly lower compared with those in periodontitis patients with normal cognitive function. Conclusion ·The periodontal condition of periodontitis patients with Alzheimer′s disease is worse compared to that of periodontitis patients with normal cognitive function. The expression of Th17-related pro-inflammatory cytokines is elevated, while the expression of Treg-related anti-inflammatory factors is decreased. Thus, periodontitis may affect the development of Alzheimer′s disease by mediating Th17/Treg-related chronic inflammatory responses.
