[摘要] 目的 探讨老年抑郁症患者血清神经活性甾体水平变化及与认知功能的相关性。 方法 选取2017年1月~2018年7月期间我院诊治的60例老年抑郁症患者为研究组,选取同时期年龄、文化程度匹配的健康志愿者60例为对照组。检测其血清神经活性甾体相关指标及认知功能,比较两组差异,并进行相关性分析。 结果 (1)与对照组相比,研究组患者血清DHEA-S、T、E2水平均明显降低(P<0.01)。DSF、DSB、MMSE明显降低(P<0.01),TMTA、TMTB、TMT(B-A)明显增加(P<0.01)。(2)血清DHEA-S、T水平与DSF、DSB、MMSE评分呈正相关(均P<0.05),与TMTA、TMTB、TMT(B-A)值呈负相关(P均<0.05)。血清E2水平与MMSE值呈正相关(P<0.05),与TMTB、TMT(B-A)值呈负相关性(P<0.05),与DSF、DSB、TMTA均无明显相关性(P均>0.05)。血清P水平与DSF、DSB、TMTA、TMTB、TMT(B-A)值、MMSE评分均无明显相关性(P均>0.05)。 结论 老年抑郁症患者存在血清神经活性甾体DHEA-S、T、E2水平降低及认知功能损害,患者血清DHEA-S、T、E2水平降低與认知功能损害相关。

[Abstract] Objective To explore the changes of serum neuroactive steroid levels and their correlation with cognitive function in elderly patients with depression. Methods Sixty elderly patients with depression diagnosed and treated in our hospital from January 2017 to July 2018 were selected as the study group, and 60 healthy volunteers with the same age and education level were selected as the control group. The serum neuroactive steroid-related indicators and cognitive function were detected and compared, and correlation analysis was performed. Results (1) Compared with the control group, serum dehydroepiandrosterone sulfate(DHEA-S), testosterone(T), estradiol(E2), digit span-forward task(DSF), digit span-backward task(DSB), and mini-mental state examination(MMSE) levels in the study group decreased significantly(P<0.01), and trail-making test part A(TMTA), trail-making test part B(TMTB), TMT(B-A) increased significantly(P<0.01). (2) Serum DHEA-S and T levels were positively correlated with DSF, DSB, and MMSE scores(all P<0.05), and negatively correlated with TMTA, TMTB, and TMT(B-A) values(all P<0.05). Serum E2 level was positively correlated with MMSE values(P<0.05), negatively correlated with TMTB and TMT(B-A) values(P<0.05), and had no significant correlation with DSF, DSB, and TMTA(all P>0.05). There was no significant correlation between serum P levels and DSF, DSB, TMTA, TMTB, TMT(B-A) values, and MMSE scores(all P>0.05). Conclusion Decreased serum neuroactive steroids DHEA-S, T, E2 and cognitive impairment are presented in elderly patients with depression, and decreased serum DHEA-S, T, E2 levels are associated with cognitive impairment.

老年抑郁癥(Geriatric depression,GD)指存在于老年期(≥60岁)这一特定人群的抑郁症,临床表现为焦虑、激越、迟缓症状较突出,而抑郁心境不典型[1],老年抑郁症患者常伴有认知功能损害,涉及记忆功能、执行功能、注意力、认知加工速度等多个方面[2]。研究显示,血清硫酸脱氢表雄酮、睾酮、雌二醇等神经活性甾体水平下降与阿尔茨海默病、抑郁症等有关,并在认知障碍中扮演了重要角色[3-4]。本研究中首次以血清神经活性甾体指标血清硫酸脱氢表雄酮(Dehydroepiandrosterone sulfate,DHEA-S)、睾酮(Testosterone,T)、雌二醇(Estradiol,E2)及孕酮(Progesterone prog,P)为目标因子,选取60~70岁老年人为目标人群,避免年龄因素对血清神经活性甾体水平及认知功能的影响,探讨老年抑郁症患者神经活性甾体与认知功能之间的关系,以期对老年抑郁症患者认知功能损害的早期预警提供参考,现报道如下。……p>
