干扰素-释放试验 (IGRA) 是识别结核病感染 (TBI) 的关键. 它们在风险适应策略中的量化,纵向使用对于消除结核病的努力至关重要.
科学领域:
- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
- 公共卫生 公共卫生
背景情况:
- 结核病感染 (TBI) 影响全球四分之一的人口,作为结核病 (TBD) 的主要储存库.
- 干扰素释测试 (IGRA) 对TBI检测至关重要,特别是在免疫能力强的个体和高Bacillus Calmette-Guérin疫苗接种率的地区.
研究的目的:
- 审查IGRA在结核病消除战略中的作用,重点关注免疫能力强的个体.
- 综合IGRA性能,感染状态的解释和结核病控制中的未来应用的证据.
主要方法:
- 关于IGRA在结核病消除中的使用现有证据的叙述性综述.
- 讨论IGRA原则,平台性能和IGRA定义的感染状态 (阳性,转化,逆转,负性).
主要成果:
- IGRA提供TBI患病率的全球估计,并在不同的流行病学背景下表现不同.
- 了解IGRA定义的感染状态需要考虑暴露,宿主易感性和进展风险.
结论:
- 在结核病消除方面,IGRA的未来效用取决于在风险适应框架内的量化,纵向应用.
- 将IGRA数据与免疫反应大小,暴露史和宿主因素相结合,对于有针对性的预防干预和推进世卫组织结核病终结战略至关重要.

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...
Pulmonary Tuberculosis I
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.

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
