同时感染SARS-CoV-2和结核病 (TB) 会增加死亡率. 了解共感染患者的免疫反应对于改善结果至关重要,因为这两种病原体都调节免疫细胞,可能会损害对COVID-19的免疫力.
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:
- 在全球范围内,SARS-CoV-2和Mycobacterium结核病 (Mtb) 是主要的传染病死亡原因.
- 同时感染COVID-19和结核病 (TB) 与死亡率增加有关.
- 在共感染个体中,SARS-CoV-2和Mtb之间的免疫相互作用需要阐明.
研究的目的:
- 为了研究对SARS-CoV-2和Mtb联合感染的免疫反应.
- 分析共感染的人类和动物模型中的免疫病理反应.
- 审查有关COVID-19和结核病共感染的临床关联和免疫调节的证据.
主要方法:
- 在PubMed和预版数据库中进行系统的文献搜索 (2020年1月以后).
- 包括研究人类和动物模型的先天性和获得性免疫反应的研究.
- 评估免疫病理反应和临床试验,包括BCG疫苗接种研究.
主要成果:
- 在高结核病负担地区,同时感染的发病率可能被低估.
- 无论是SARS-CoV-2还是Mtb都能调节关键的免疫细胞,包括单细胞,巨细胞,中性粒细胞和T细胞.
- 同时感染可能导致SARS-CoV-2免疫力受损和炎症恶化,并可能调节T细胞对Mtb.的反应.
结论:
- 由于复杂的免疫相互作用,与SARS-CoV-2和Mtb的同时感染显著影响患者的结果.
- 共同感染的免疫调节会导致炎症反应加剧和T细胞动态变化.
- 目前的证据不支持BCG疫苗接种对COVID-19的临床益处.

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.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
Pulmonary Tuberculosis II
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...
Pulmonary Tuberculosis V
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 IV
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...
