概括

滴滴数字PCR (ddPCR) 在诊断脊髓结核病 (STB) 时显示出高灵敏度. 这种方法证实,在接受抗逆转录病毒治疗的HIV-1感染者脊髓组织中,Mycobacterium tuberculosis (Mtb) 和HIV-1DNA水平同时增加.

科学领域:

传染性疾病传染性疾病
分子诊断学分子诊断学
病毒学病毒学

背景情况:

脊柱结核病 (STB) 的诊断是具有挑战性的,因为Mycobacterium结核病 (Mtb) 的 paucibacillary性质.
在脊髓组织中与HIV-1的同时感染可能会促进HIV-1 (PLWH) 感染者接受抗逆转录病毒治疗 (ART) 的相互复制和储库扩张,但证据有限.

研究的目的:

评估滴滴数字PCR (ddPCR) 检测和量化脊髓活检组织中的Mtb DNA.
为了验证ddPCR对培养和Xpert MTB/RIF Ultra的敏感性.
为了确定Mtb和HIV-1DNA丰度是否在脊柱共感染部位增加.

主要方法:

从93个脊髓活检细分中提取DNA,这些细分来自南非的成年人,这些成年人可能患有STB.
使用ddPCR对Mtb复合体 (MTBC),HIV-1和人类基因进行量化.
分析包括了52%的参与者,这些参与者是接受ART的PLWH.

主要成果:

ddPCR检测到100%的培养证实STB病例和83%的Xpert超级证实STB病例中的MTBCDNA.
在PLWH活检中,mtb DNA (rpoB副本/10^6人体细胞) 的含量较高,与HIV-1 DNA水平相关.
艾滋病毒-1 DNA 在与共检测的MTBC DNA 的段落中较高,并且与病毒载量相关.

结论:

ddPCR显示了STB诊断的高灵敏度.
证实了MTb与ART中PLWH在脊髓组织中的HIV-1丰度之间的相互关系.
对共感染组织的免疫微环境进行进一步的研究是有必要的,以了解储库持久性.

Pulmonary Tuberculosis IV

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
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...

Pulmonary Tuberculosis III

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Pulmonary Tuberculosis I

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.
Mode of...
