概括

抗体测量可以检测治疗中断后几周的HIV病毒载荷反弹. 这为当前的艾滋病毒监测方法提供了更简单,更快,更便宜的替代方案.

科学领域:

免疫学免疫学免疫学
病毒学病毒学
临床医学临床医学

背景情况:

基于聚合酶连锁反应 (PCR) 的HIV病毒载量 (VL) 测试对于治疗监测至关重要,但资源密集.
开发成本效益和可访问的替代方案来监测HIVVL是一个重要的公共卫生需求.

研究的目的:

调查抗体测量在检测治疗中断期间病毒载荷反弹中的实用性.
利用分析性治疗中断 (ATI) 研究 (NCT03225118) 的数据来评估抗体动态.

主要方法:

在一项ATI研究中,从22名参与者的长度血清样本中使用限制抗原 (LAg) 抗体测定进行了分析,测量了正常化的光密度 (ODn).
用贝叶斯推断来适应线性混合效应模型,分析VL变化和ODn波动之间的时间滞后,以及病毒再抑制后ODn变化率.

主要成果:

在治疗中断后大约4.36周和检测到VL后2.78周,LAgODn增加了.
抗体水平在VL达到峰值后大约一周达到峰值,显示1.70倍的增加.
在病毒再抑制之后,ODn在一年内以每周-0.015单位的速度下降.

结论:

在治疗中断期间,在检测到VL后的2-4周内,LAg抗体水平持续上升.
纵向抗体测量显示了支持简单,快速和低成本的艾滋病毒治疗监测的希望.

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...
