五种血清生物标志物的组合,包括pepsinogen I (PGI),PGII,PGI/II比率,胃素-17 (G-17) 和抗H. pylori抗体,可以有效地查慢性缩性胃炎. 这种多生物标志物方法提高了识别高风险个体的预测准确性.
科学领域:
- 胃肠病学 胃肠病学
- 生物标志物发现发现
- 疾病查 疾病查
背景情况:
- 慢性缩性胃炎 (CAG) 构成严重的健康风险.
- 高风险人群的有效查对于早期干预至关重要.
- 目前的查方法需要改进,以适用于一般人口.
研究的目的:
- 开发和验证使用血清生物标志物的慢性缩性胃炎的预测模型.
- 评估组合生物标志物的有效性,以识别CAG的高风险个体.
- 为CAG建立一个非侵入性查工具.
主要方法:
- 血清样本被分析为五个关键生物标志物:pepsinogen I (PGI),PGII,PGI/II比,胃素-17 (G-17) 和抗H. pylori抗体.
- 进行了横截面分析,以评估每个生物标志物与CAG的关联.
- 开发了一个包含所有五种生物标志物的预测模型.
主要成果:
- PGII,PGI/II比率,G-17和抗H. pyloriIgG与慢性缩性胃炎的存在有积极联系.
- 使用所有五种生物标志物的综合预测模型显示,与单个生物标志物相比,精度更高 (0.692).
- 个别生物标志物的预测值在0.54到0.629.9之间.
结论:
- PGI,PGII,PGI/II比率,G-17和抗H. pylori抗体的组合提供了慢性缩性胃炎的有效血清查工具.
- 这种多生物标志物小组有助于识别一般人群中高风险个体.
- 被确定为高风险的个人应该接受进一步的诊断程序,如内镜和活检.

Gastritis-I: Introduction and Types
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
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...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
