杆菌 (Hp) 感染在牛皮病中显示出不同的抗体反应. 虽然一些hp抗原在牛皮和牛皮性关节炎患者中更频繁地成为目标,但整体hp阳性并不不同,质疑直接联系.
科学领域:
- 免疫学 免疫学 免疫学
- 微生物学 微生物学
- 皮肤病学 皮肤病学
背景情况:
- 杆菌 (Hp) 是一种可疑的传染病触发者,可引起诸如牛皮 (Ps) 和牛皮关节炎 (PsA) 等牛皮病.
- 之前的研究缺乏对PsA,Ps和健康对照 (HCs) 中不同Hp抗原的抗体 (ab) 反应性的全面分析.
研究的目的:
- 在PsA,Ps和HC中调查针对主导和亚主导Hp抗原的详细抗体反应性.
- 为了确定HP感染是否与牛皮疾病的发病因子免疫学相关.
主要方法:
- 从89名PsA患者,114名Ps患者和60名HC患者收集了血清样本.
- 进行IgG抗Hp抗体测试,使用免疫阻塞和线路测试来检测针对特定Hp抗原的反应性.
- 分析的抗体频率和水平与疾病状况和临床评分相关 (例如,DAS28).
主要成果:
- 总体而言,抗Hp抗体阳性在PsA,Ps和HC之间没有显著差异.
- 与HC相比,PsA和Ps患者的Hp抗原特异性抗体 (例如p75,p66-UreB,p54-flagellin) 在PsA和Ps患者中更频繁.
- 与Ps患者相比,PsA患者观察到某些抗体的水平更高.
- 在PSA患者中,DAS28评分和抗p19抗体水平之间发现了正相关性.
结论:
- 虽然对HP的特异抗原-抗体反应在牛皮病患者中更为普遍,但整体阳性差异的缺乏引发了问题.
- 杆菌和牛皮病之间的免疫学联系仍然不确定,需要进一步调查.
- 这些发现表明存在复杂的关系,可能涉及特定的免疫反应,而不是一般的感染触发因素.

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.

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...

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...
