概括
杆菌 (Hp) 感染可能导致心肌梗塞 (MI) 患者的炎症,由高C反应蛋白 (CRP) 表示. 虽然HP本身并没有预测不良心血管事件,但其相关的炎症生物标志物确实如此.
科学领域:
- 心脏病学 心脏病学
- 传染性疾病 传染性疾病
- 生物标志物研究 生物标志物研究
背景情况:
- 杆菌 (Hp) 和其毒性因子细胞毒素相关基因A (CagA) 被怀疑是心肌梗塞 (MI) 的贡献者.
- 将HP感染与心血管疾病联系在一起的确切机制在很大程度上是未知的.
- 这项研究调查了HP感染,炎症生物标志物和心血管结果之间的关联.
研究的目的:
- 确定HP感染和CagA是否与MI患者的特定炎症和血管生物标志物有关.
- 探索HP感染广泛生物标志物小组的预测能力.
- 评估HP感染,生物标志物和主要不良心血管事件 (MACE) 与死亡率之间的关系.
主要方法:
- 在1061名MI患者 (2008-2014) 中分析了Hp,CagA血清学和175个心血管生物标志物.
- 评估了Hp与7个预先选择的生物标志物之间的关联.
- 使用机器学习来预测Hp状态,使用所有生物标志物和Cox回归来分析结果.
主要成果:
- 血清流行率的Hp和CagA分别为45%和19%.
- 阳性HP患者显示C反应蛋白 (CRP) 的升高.
- 在Hp阳性个体中发现了较高的C-C动机化学基因连接体20 (CCL20) 和免疫球蛋白重常数-3 (IGHG3),以及较低的TNF相关亡诱导连接体 (TRAIL). 升高的CCL20和降低的TRAIL,而不是Hp,与MACE和死亡率相关.
结论:
- 肝炎感染可能会促进心脏病发作患者的炎症反应,其证据是CRP升高和特定的炎症生物标志物.
- 虽然HP感染与MI后不良结果没有直接关联,但其相关的预测性炎症生物标志物 (CCL20, TRAIL) 与MACE和死亡率有显著的关联.

Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy
1.9K
Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...

Gastritis III: Clinical Manifestations and Management
1.6K
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...

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
750
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-II: Pathophysiology
1.7K
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...
