概括
药物诱导性肝损伤 (DILI) 涉及免疫系统的反应,因此很难区分自免疫性肝炎. 新的表型,如药物诱导的自身免疫性肝炎和检查点抑制剂损伤,带来了独特的诊断挑战.
科学领域:
- 免疫学 免疫学 免疫学
- 肝病学 肝病学是一种肝病学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 药物诱导性肝损伤 (DILI) 是一种罕见的,严重的疾病.
- 非同步性DILI是不可预测和剂量独立的,影响少数患者.
- 免疫系统,特别是人类白细胞抗原 (HLA) 多态,在DILI中起着关键作用.
研究的目的:
- 探索DILI的免疫学基础.
- 为了区分DILI与自身免疫性肝炎 (AIH).
- 描述新的DILI表型,如药物诱导的自身免疫性肝炎 (DI-ALH) 和检查点抑制剂 (CPI) 诱导的肝损伤.
主要方法:
- 在DILI.免疫学过程的审查.
- DILI和AIH之间的实验室和组织学参数的比较.
- 对CPI诱导的肝损伤和与疫苗接种相关的肝损伤中明显的组织病理模式的分析.
主要成果:
- 在DILI和AIH实验室和组织学发现之间存在显著的重叠.
- DI-ALH 呈现自身免疫特征,对皮质类固醇有反应,没有复发.
- CPI诱导的肝损伤显示了粒状肝炎和细胞毒性T细胞透,与AIH不同.
结论:
- 由于共享的免疫机制,区分DILI和AIH在临床上具有挑战性.
- 像DI-ALH和CPI诱导的肝损伤这样的新型DILI表型具有独特的免疫和临床特征.
- 了解这些免疫介导的肝损伤对于准确的诊断和管理至关重要.

Autoimmune Disorders
436
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Gastritis-II: Pathophysiology
326
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.

Allergic Drug Reactions
842
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...
