Alz Res Therap:痴呆患者,患新冠后有何临床特点?

2021-12-06 Freemann MedSci原创

痴呆症患者的COVID-19与SARS-CoV-2感染的严重结果有关

因为新冠,截至2021年2月4日,全球已经有超过1亿个病例和200万人死亡。COVID-19感染的临床范围似乎很广,包括无症状感染、轻度上呼吸道疾病和严重肺炎,并伴有呼吸衰竭、系统并发症和多器官衰竭。

与普通成年人相比,严重的COVID-19影响患有慢性疾病的老年人,包括认知能力下降,比例很高。

根据最近的研究,痴呆症是COVID-19严重性的一个主要风险因素。同时,在痴呆症患者中,暴露于感染的风险更为重要,在长期护理设施、频繁住院和智力下降的情况下,暴露于感染的风险很高。

到目前为止,痴呆患者COVID-19的具体临床特征和预后因素仍不清楚。为了确定痴呆症患者的具体特征和死亡风险因素,法国国立卫生研究院的 Vrillon等人,报告了一项对125名因确诊COVID-19感染而住院的痴呆症患者的队列研究。

他们于2020年3月14日至2020年5月7日在法国巴黎的2个老年COVID中心,进行了前瞻性研究。因确诊COVID-19感染而住院的痴呆症患者被系统地纳入研究。进行了二元逻辑回归分析,以确定与21天后的死亡率相关的因素。

他们共纳入了125名患者,中位年龄为86岁(IQI为82-90);59.4%为女性。最常见的痴呆原因是阿尔茨海默氏病、混合性痴呆和血管性痴呆。

67.2%的人有≥2种并发症;40.2%的人住在长期护理机构。COVID-19发病时最常见的症状是混乱和谵妄(82.4%),气喘(76.8%)和发烧(72.8%),然后是多痰(51.2%)和脱水(50.4%)。

跌倒在疾病的初始阶段很常见(35.2%)。21天时的死亡率为22.4%。慢性肾脏疾病和入院时的CRP是死亡的独立因素。在幸存者中观察到持续的困惑、情绪和行为紊乱(19.2%)。

这个研究的重要意义在于发现了: 痴呆症患者的COVID-19与SARS-CoV-2感染的严重结果有关,并具有特定的临床特征和并发症,其中意识模糊和谵妄是最主要的。在与基线相比有任何明显变化时,应考虑进行COVID-19检测。
