Infection:抗生素治疗并不能改善新冠病毒感染患者的全因死亡率和疾病进展

2021-10-18 MedSci原创 MedSci原创

由于在流感等呼吸道病毒感染中,细菌重叠感染可导致更高的发病率和死亡率,需要及时诊断并开始抗生素治疗 (ABT)。

    由于在流感等呼吸道病毒感染中,细菌重叠感染可导致更高的发病率和死亡率,需要及时诊断并开始抗生素治疗 (ABT)。2019 年冠状病毒病 (COVID-19) 中报告的抗生素使用率远高于细菌共感染和重复感染的实际比例,因此,探究细菌感染在新冠患者中的作用,以及它们对临床病程的影响以及抗生素在主要病毒性呼吸道疾病中的使用变得越来越重要。本项研究旨在探究抗生素治疗是否可以改善新冠病毒感染患者的全因死亡率和疾病进展。

 

      研究人员将LEOSS队列中的时间介于2020年3月18日至2021年2月16日之间的6457 例 SARS-CoV-2 感染病例纳入本项研究。对于处于疾病复杂阶段且降钙素原 (PCT) ≤ 0.5 ng/ml 的成年患者,在剔除了混杂因素如性别、年龄和合并症后,对抗生素治疗与全因死亡率的相关性进行了分析。

 

      最后,总共有3627例患者符合分析纳入标准。对于主要观察终点,研究人员发现抗生素治疗与较低的全因死亡率或进展到下一个更严重的疾病阶段(n=996)无关(p>0.05)。对于次要观察终点, 无论PCT水平如何,处于无并发症期的患者 ( n=1195) 的全因死亡率并没有降低,并且在接受抗生素治疗时,进展到下一个更复杂病情的患者并没有减少 ( p>0.05)。虽然PCT>0.5 ng/ml 和抗生素治疗的复杂病情患者(n=286)的全因死亡率显着增加(p=0.029) 但进展到更严重疾病阶段的概率没有显着差异 ( p>0.05)。

 

      本项研究证实SARS-CoV-2 感染患者接受抗生素治疗并不会对全因死亡率或疾病进展有改善作用。
