摘要:

目的研究轻度认知障碍(mild cognitive impairment,MCI)老年人血清亚精胺(spermidine,SPD)含量水平。方法根据蒙特利尔认知评估(montreal cognitive assessment scale,MoCA)量表得分、性别、文化程度、年龄进行1∶1匹配病例组(轻度认知障碍者)与对照组(认知功能正常者),分析血清SPD含量的分布及组间SPD水平差异。结果共纳入研究对象28对,平均年龄为(73.07 ± 5.72)岁,其中男性12对(42.9%),女性16对(57.1%)。病例组与对照组的年龄差异无统计学意义(P >0.05),MoCA得分比较差异具有统计学意义(P< 0.001)。对照组血清SPD含量54.6(51.8,60.5)ng/mL,高于病例组血清SPD含量29.5(26.0,34.7)ng/mL,差异有统计学意义(P< 0.001)。血清SPD含量与MoCA得分存在线性相关关系(rs= 0.751,P< 0.001)。结论老年人的MoCA得分与其血清SPD之间存在正相关关系,MCI老年人血清SPD水平较低,提示动态监测血清SPD水平可有助于早期MCI的发现与诊断,并需要进一步研究可能的干预措施,如通过摄入高多胺食物或外源性SPD补充剂提高血清SPD水平是否可预防或延缓MCI及阿尔茨海默病的进展。

Abstract:

ObjectiveTo study the serum levels of spermidine (SPD) in elderly individuals with mild cognitive impairment (MCI).MethodsA 1∶1 matched case-control study was conducted, according to the scores of the Montreal Cognitive Assessment (MoCA), gender, educational level, and an age difference of no more than 2 years; 28 pairs of cases (people of mild cognitive impairment) and controls (people of normal cognition) were matched. The distribution of serum spermidine content (SPD) and the differences of SPD level between two groups were analyzed.ResultsTwenty-eight pairs of study subjects were included, with an average age of (73.07 ± 5.72) years, 12 pairs of males (42.9%) and 16 pairs of females (57.1%). There was no statistically significant difference in age between the case group and the control group (P= 0.412), while there was a statistically significant difference in MoCA scores (P< 0.001) between the two groups. The serum spermidine level of the control group 54.6 (51.8, 60.5) ng/ml was higher than that of the case group 29.5 (26.0, 34.7) ng/ml, and there was a statistically significant difference (P< 0.001). There is a positive linear correlation between serum spermidine level and MoCA score (rs= 0.751,P< 0.001).ConclusionThere is a negative correlation between the MoCA scores and the serum spermidine in elderly people. Elderly people with mild cognitive impairment have lower levels of serum spermidine. These suggests that (1) dynamic monitoring of serum spermidine levels can contribute to the discovery and diagnosis of MCI earlier; (2) further researches are needed on intervention measures. such as whether increasing serum spermidine levels through intake of high polyamine foods or exogenous spermidine supplements can prevent or delay the progression of MCI and Alzheimer’s disease or not.
