杆菌 (Hp) 感染会改变胃分泌,而Hp-I和Hp-II菌株会降低功能. 消灭HP后胃功能恢复正常,HP感染会影响不依年龄的胃素-17水平.
科学领域:
- 胃肠病学 胃肠病学
- 微生物学 微生物学
- 临床医学 临床医学
背景情况:
- 杆菌 (Hp) 感染与各种胃病有关.
- 胃分泌的改变在与HP相关的疾病中很常见.
- 不同HP菌株对胃功能的特定影响需要进一步阐明.
研究的目的:
- 为了研究不同Helicobacter pylori (Hp) 菌株对胃分泌功能的影响.
- 为了比较不同HP型感染患者和未感染患者的胃功能.
主要方法:
- 这是一项涉及525名患者的横截面临床研究.
- 血清标记物的分析包括细胞毒素相关蛋白质基因A (CagA),真空化细胞毒素相关蛋白质基因A (VacA),尿素酶 (Ure),胃蛋白-17 (G-17),Pepsinogen I (PGI),Pepsinogen II (PGII) 和PGI/PGII比率 (PGR).
主要成果:
- 与未感染者相比,HP感染的个体显示出较高的PGII水平和较低的PGR水平.
- 与未感染组相比,Hp-I和Hp-II感染组的PGR水平显著较低.
- 在未感染个体中,胃素-17 (G-17) 水平与年龄和胃分泌标记有积极的相关性,但在HP感染群体中没有.
结论:
- 无论患者的年龄或性别,Hp-I (具有CagA和/或VacA) 和Hp-II菌株都会损害胃分泌功能.
- 经过HP根除的患者的胃功能与未感染个体的功能相当.
- 虽然Gastrin-17自然会随着年龄的增长而增加,但HP感染显著影响这些水平.

Pathophysiology of Peptic Ulcer Disease: Injurious Factors
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds...

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-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...
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

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,...
