medRxiv : the preprint server for health sciences
|October 3, 2025
概括
与艾滋病毒相关的结核性脑膜炎 (TBM) 的死亡率与低脑脊液 (CSF) 炎症有关. 增强CSF干扰素-马可能会改善这些TBM患者的生存率.
科学领域:
- 神经科学是一个神经科学.
- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
背景情况:
- 结核性脑膜炎 (TBM) 具有显著的死亡风险,特别是在艾滋病毒感染者中.
- 皮质类固醇治疗改善了艾滋病毒阴性TBM的结果,但没有改善艾滋病毒感染者的结果.
- 了解与艾滋病毒相关的TBM中的免疫反应对于改善患者生存至关重要.
研究的目的:
- 研究大脑脊髓液 (CSF) 的局部免疫动态与艾滋病毒相关的TBM成年人死亡率之间的关联.
- 确定特定的免疫媒介,预测该患者群体的结果.
主要方法:
- 在乌干达的149名艾滋病毒和TBM的成年人中测量了基线的CSF免疫信号介质.
- 患者接受了标准的抗菌素和皮质类固醇治疗.
- 与90天死亡率相关的免疫媒介度.
主要成果:
- 不幸存者表现出更严重的TBM和较低的血液CD4T细胞计数.
- 死亡率与CSF低炎症密切相关.
- 较高的CSF干扰素马 (IFN-γ) 水平与较低的死亡率相关;低的IFN-γ增加了死亡风险.
- 中间CSF中白蛋白-13水平与死亡率降低有关.
- 在患有CD4枯竭和CSF低IFN-γ的患者中,观察到的死亡率最高.
结论:
- 用德甲治疗的与艾滋病毒相关的TBM中的死亡率与减少的CSF炎症有关.
- 目前的类固醇治疗可能对所有患者来说都不够.
- 针对特定免疫反应的个性化免疫治疗策略是必要的,以改善HIV-TBM的结果.

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.

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Pulmonary Tuberculosis II

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
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...
