概括

"不可检测=不可传播" (U=U) 的HIV概念至关重要. 目前的敏感测试在200拷贝/毫升以下会造成混乱,可能会对患者造成伤害,但没有明显的益处.

科学领域:

病毒学病毒学
公共卫生公共卫生
传染性疾病传染性疾病

背景情况:

"不可检测=不可传播" (U=U) 概念彻底改变了艾滋病毒的预防和治疗.
从历史上看,HIV RNA病毒载荷 (VL) 低于200个拷贝/毫升定义了U=U研究的不可检测性.
越来越敏感的VL测定现在检测到低于20副本/毫升的水平,导致定义混乱.

研究的目的:

为了解决围绕HIV"不可检测"病毒载荷 (VL) 的定义的混.
评估VLs在检测下限 (LLD) 和200拷贝/毫升之间的临床意义.
提议改善VL报告和患者咨询有关艾滋病毒传播的情况.

主要方法:

对U=U和病毒载荷测定现有研究的审查.
分析高度敏感的VL测试对艾滋病毒管理的影响.
讨论报告非常低VLs的临床益处和潜在危害.

主要成果:

在LLD (例如,20拷贝/毫升) 和200拷贝/毫升之间的VL与未来的病毒学失败有关.
在此范围内的VL患者中进行干预没有证明的临床益处.
目前对低VL的报告实践可能是有害的,因为缺乏明显的好处.

结论:

过于敏感的VL测试可以在U = U的背景下造成混乱和潜在的伤害.
提出了调整VL报告门和加强提供商咨询的建议.
需要进一步的研究来减轻与高度敏感的VL测试相关的危害,并澄清U = U定义.

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...

Pulmonary Tuberculosis I

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...
