概括

更高的人类白细胞抗原进化分歧 (HED) 类II水平可能会减少等待肝移植 (LT) 的肝硬化患者的细菌感染. 这一发现表明一种潜在的免疫机制影响了这一脆弱人群的感染风险.

科学领域:

免疫学免疫学免疫学
肝病学肝病学是一种肝病学.
移植移植移植移植

背景情况:

细菌感染是肝硬化患者的重要并发症,增加死亡率和脱补偿的风险.
人类白细胞抗原进化分歧 (HED) 在调节肝硬化感染风险中的作用仍然未被探索.

研究的目的:

研究HLA类I和II进化分歧 (HED) 与等待肝脏移植 (LT) 肝硬化患者细菌感染的发生率之间的关联.
为了确定HED是否影响肝硬化脱补偿的风险.

主要方法:

对269名等待LT治疗的肝硬化患者的回顾性研究 (2019年1月 - 2022年2月).
分析与细菌感染和脱补偿事件有关的HLA类I和II-HED.
多变量分析以确定感染的独立风险因素.

主要成果:

更高的II类HED显著与细菌感染风险降低相关 (p=0.034).
I类HED对感染风险没有显著影响 (p=0.074).
感染的独立风险因素包括侵袭性手术,ICU住院,最近的抗生素,利法西明使用和脱补偿.

结论:

升高的II类HED可能会在LT前肝硬化患者中保护他们免受细菌感染.
无论是I类还是II类-HED都没有影响肝硬化不补偿的风险.
研究结果表明,HED在肝硬化中的感染易感性方面具有潜在的免疫作用.

Tissue Transplantation

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
The Biology of Tissue Transplantation
The biology of tissue transplantation hinges on the Major Histocompatibility Complex (MHC) molecules. These molecules...

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...
