植物血凝-干扰因子-释测试 (PHA-IGRA) 可能会对肝硬化患者的免疫功能障碍进行分类. 降低干扰素马释放与疾病严重程度的增加相关,这表明PHA-IGRA.
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.
- 临床诊断 临床诊断 临床诊断
背景情况:
- 肝硬化导致免疫功能障碍,增加感染易感性.
- 评估肝硬化患者的免疫功能至关重要,但具有挑战性.
- 现有的淋巴细胞检测方法缺乏对不同肝硬化阶段的评估.
研究的目的:
- 在肝硬化患者中使用植物血凝素 (PHA) 评估干扰素释测试 (IGRA).
- 为了确定PHA-IGRA是否可以对免疫功能和疾病严重程度进行分类.
- 评估PHA-IGRA结果与临床参数之间的相关性.
主要方法:
- 试点研究涉及70名等待肝移植的肝硬化患者.
- 全血干扰素-玛 (IFN-γ) 释放试验使用PHA,一种非抗原性线粒原体.
- 测量IFN-γ在疾病严重程度范围内的反应 (慢性肝硬化到急性-慢性肝衰竭).
主要成果:
- 通过PHA刺激的IFN-γ释放的逐渐减少与疾病严重程度的增加相关.
- 观察到IFN-γ释放和CD8+ T淋巴细胞计数 (r=0.52,P <0.001) 之间存在显著的相关性.
- PHA-IGRA证明了对淋巴细胞IFN-γ释放能力的全球评估的潜力.
结论:
- PHA-IGRA测试可以作为一种有价值的工具来表征肝硬化中的免疫功能障碍.
- 研究结果表明,PHA-IGRA可以帮助根据疾病严重程度对免疫功能进行分类.
- 需要在更大的队列中进一步验证以确定临床适用性.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
