概括

尼尔马特里尔维尔 - 里托纳维尔 (N-R) 治疗COVID-19与更高的病毒学反弹 (VR) 频率有关. 这种反弹涉及复制能力强的病毒的流失,即使没有症状复发.

科学领域:

传染性疾病传染性疾病
病毒学病毒学
药理学药理学是指药理学的学科.

背景情况:

关于治疗急性COVID-19和病毒学反弹 (VR) 之间的关联,存在相互矛盾的数据.
了解VR对于管理COVID-19治疗疗效和传播风险至关重要.

研究的目的:

为了比较N-R治疗的患者和未接受N-R治疗的急性COVID-19患者的病毒学反弹 (VR) 频率.
研究NR治疗后VR的特征和影响.

主要方法:

进行了一项观察性队列研究,涉及急性COVID-19的门诊成年人.
参与者被分为两组:接受5天NR治疗的人和没有接受COVID-19治疗的人.
病毒学反弹是由特定的标准定义的,包括在负结果或显著的病毒载量增加后的积极病毒培养.

主要成果:

接受N-R治疗的15名参与者 (20.8%) 经历了病毒学反弹 (VR),而未接受治疗的组中只有1名参与者 (1.8%).
在多变量模型中,N-R使用与VR有显著的关联 (调整后的几率比率10.02).
当N-R疗法在症状发作后2天内开始时,VR更为常见,并且与长时间的复制能力病毒流失有关.

结论:

病毒学反弹发生在大约每5名接受COVID-19N-R治疗的1名患者中.
虚拟现实与能够复制的病毒的分泌有关,无论症状是否反弹.
该研究强调需要进一步调查NR治疗后VR的临床意义和管理.

Retrovirus Life Cycles

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...
