概括
基于多卢特格拉维尔的抗逆转录病毒疗法 (ART) 是有效的二线艾滋病毒治疗,即使有先前的耐药性. 长期结局显示持续的病毒抑制,多卢特格拉维尔耐药性的发病率较低.
科学领域:
- 传染性疾病 传染性疾病
- 病毒学 病毒学
- 临床药理学 临床药理学
背景情况:
- 针对HIV-1感染的二线抗逆转录病毒疗法 (ART) 需要仔细选择药物.
- 多卢特格拉维尔 (DTG) 是现代ART疗法的关键组成部分.
- 了解基于DTG的二线ART的长期结果至关重要,特别是在先前耐药性患者中.
研究的目的:
- 在接受二线ART的患者中,评估切换到tenofovir-lamivudine-dolutegravir (TLD) 的长期病毒学结果.
- 评估这种患者群体中耐药性的发生率,特别是对多卢特格拉维尔的耐药性.
主要方法:
- 进行了一项随机的,双盲的II期临床试验 (ARTIST).
- 两次连续HIV-1RNA水平≥1000拷贝/毫升的参与者在一线ART上被切换到TLD.
- 长期结果被评估到158周,包括病毒载量和耐药性测试.
主要成果:
- 很高比例的参与者 (78%在158周) 保持病毒载量<50拷贝/毫升,即使有先前存在的tenofovir和lamivudine耐药性.
- 杜洛特格拉维尔耐药性的出现很低,在2-3年后观察到约1%的参与者.
- 到第158周,病毒载量反弹发生在11%的参与者身上.
结论:
- 切换到TLD是一种有效的二线ART策略,适用于可检测HIV-1RNA的成年人和对较旧药物的实质性耐药性.
- 持续的病毒抑制可以在长期内实现,出现多卢特格拉维尔耐药性的风险很低.
- 这些发现支持在二线ART治疗方案中使用TLD来管理HIV-1感染.

Retrovirus Life Cycles
45.4K
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 V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
