概括
在41%的非酒精性脂肪性肝病 (NAFLD) 病例中存在自身抗体,但与疾病严重程度无关. 然而,像CK18-M30这样的肝损伤标志物随着NAFLD的进展而增加.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 免疫学 免疫学 免疫学
- 内部医学 内部医学
背景情况:
- 非酒精性脂肪性肝病 (NAFLD) 是一系列的肝病.
- 自动抗体和NAFLD组织学严重程度之间的关联尚未得到充分证实.
- 不一致的先前报道需要进一步调查这种关系.
研究的目的:
- 确定自身抗体对NAFLD组织学严重性的影响.
- 分析NAFLD患者自身抗体的患病率.
- 为了将自身抗体存在与肝脏炎和纤维化标志物的相关性.
主要方法:
- 在2016年1月至2021年1月期间诊断的NAFLD病例的回顾性分析.
- 自体抗体的评估包括抗核抗体 (ANA),抗平滑肌抗体 (ASMA) 和抗肝微体抗体 (LKM-1).
- 对血清CK18-M30和PIIINP水平的评估,以测量死亡炎症和纤维化.
主要成果:
- 在683名研究的NAFLD患者中,在41.1%的患者中检测到自身抗体.
- 具有和没有自身抗体的患者之间没有观察到组织学参数的显著差异.
- 虽然自身抗体与严重程度无关,但CK18-M30和PIIINP水平显示出随着疾病进展的上升趋势 (NAFL到NASH到NASH+AIH).
结论:

Gastritis-II: Pathophysiology
371
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...
