概括
一种用于检测缩性胃炎 (AG) 的新侧流量试验 (LFA) 显示了与ELISA可比的诊断性能. 这种快速的,非侵入性的测试是早期在护理场所检测AG的有希望的工具.
科学领域:
- 胃肠病学
- 生物标志物发现
- 诊断试验的发展
背景情况:
- 缩性胃炎 (AG) 的检测依赖于侵入性内镜或已确定的酶相关免疫吸收试验 (ELISA) 方法.
- 侧流检测 (LFA) 提供快速,非侵入性的生物标志物检测,但需要与AG诊断的ELISA等黄金标准进行验证.
- AG的主要生物标志物包括pepsinogen I (PGI),pepsinogen II (PGII),Gastrin-17 (G-17) 和Helicobacter pylori IgG.
研究的目的:
- 将新型多生物标志物横流试验 (LFA) 与缩性胃炎 (AG) 酶相关免疫吸收试验 (ELISA) 的诊断性能进行比较.
- 评估LFA在检测Helicobacter pylori感染和区分AG亚型,如自身免疫性胃炎中的实用性.
主要方法:
- 一项前性多中心队列研究 (前癌性胃病变的进展和回归 - - PROREGAL) 包括204名胃前癌性病变患者.
- 使用LFA和ELISA对PGI,PGII,G-17和H. pyloriIgG进行了快速血清样本分析.
- 在LFA和ELISA中比较了包括特异性和曲线下的面积 (AUC) 在内的诊断性能指标.
主要成果:
- 对于AG,LFA的诊断特异性与ELISA的诊断特异性相当 (95. 74%与100. 00%).
- 在检测H. pylori感染方面,LFA和ELISA的表现相似 (AUC为0. 754对0. 778).
- 通过降低PGI/PGII比率和通过LFA提高G-17的组合有效地发现了自身免疫性胃炎 (AUC为0. 926).
结论:
- 多生物标志物LFA是一种可行的,快速的,非侵入性的工具,用于评估胃功能性粘膜.
- 在检测缩性胃炎方面,LFA的诊断性能与ELISA相美.
- LFA 作为一个有价值的补充工具,用于改善早期检测 AG.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
200
Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Gastritis III: Clinical Manifestations and Management
474
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
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...

Enzyme-Linked Immunosorbent Assay
14.2K
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or...

Gastritis-II: Pathophysiology
543
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
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...
