概括
在接受纳塔利祖马布治疗多发性硬化症的患者中,COVID-19 限制显著降低了约翰·坎宁汉病毒 (JCV) 血清转化率. 这表明可修改的因素可能会降低这些患者的JCV风险.
科学领域:
- 神经免疫学 神经免疫学
- 病毒学 病毒学
- 流行病学 流行病学
背景情况:
- 纳塔拉利祖马布是复发性复发性多发性硬化症 (MS) 的关键疗法.
- 在约翰·坎宁汉病毒 (JCV) 阳性患者中,长期使用纳塔利祖马布可能会导致渐进的多焦点白脑病变 (PML),这是一种致命的脑部感染.
- 定期监测JCV血清状况对于接受纳塔利祖马布治疗的患者至关重要.
研究的目的:
- 为了比较在COVID-19社区限制之前和期间接受natalizumab治疗的患者的JCV血清转化率.
- 调查广泛的公共卫生干预措施对JCV血清转化动态的影响.
主要方法:
- 在皇家墨尔本医院对纳塔利祖马布接受者的JCV血清状态变化的回顾性分析.
- 两个队列的比较:COVID前 (2012-2017,n=128) 和COVID-19封锁 (2020-2022,n=214). 这两个队列的比较是:COVID前 (2012-2017,n=128) 和COVID-19封锁 (2020-2022,n=214).
- 根据年龄和性别进行调整的Poisson回归建模,以评估血清转化率差异.
主要成果:
- 年化JCV血清转化率从COVID前的9.08%下降到COVID限制期间的2.01%,减少了4.7倍.
- 在COVID-19期间,JCV血清转化显著降低 (p < 0.0001).
- 与女性相比,男性的血清转化率高出2倍.
结论:
- COVID-19限制与纳塔利祖马布治疗患者中JCV血清转化明显下降有关.
- 这些发现表明,封锁期间的环境或行为因素可能会减轻JCV血清转化.
- 对可修改的风险因素进行进一步的研究是有必要的,以减少纳塔利祖马布在MS患者的PML风险.

Retrovirus Life Cycles
46.1K
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...

Subviral Agents

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
