概括
像ANA和ASMA这样的自身抗体在代谢功能障碍相关的脂肪性肝病 (MASLD) 中很常见,并且与更糟糕的结果有关. 孤立的自身免疫组织学特征不会影响MASLD的预后.
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
- 胃肠病学 胃肠病学
背景情况:
- 与代谢功能障碍相关的脂肪性肝病 (MASLD) 是全球慢性肝病的主要原因.
- 自体抗体 (Ab),包括抗核抗体 (ANA) 和抗平滑肌肉抗体 (ASMA),通常在MASLD患者中发现,但它们的预后意义仍在争论中.
- 研究自身免疫标记在MASLD中的作用对于风险分层和个性化治疗至关重要.
研究的目的:
- 为了确定活检证明的MASLD中阳性自身抗体 (ANA,ASMA) 的患病率.
- 评估自身免疫性肝炎 (AIH) 组织学特征在MASLD中的频率.
- 评估自身抗体和组织学特征与MASLD中肝脏相关结果的关联.
主要方法:
- 在HEPAmet注册表中的460名MASLD患者的多中心,回顾性,纵向研究.
- 对ANA (≥1/80) 和ASMA (≥1/40) 血清学的分析.
- 评估AIH组织学特征 (门口炎症,接口肝炎,血细胞透) 和它们与补偿高级慢性肝病 (cACLD),肝脏衰竭和死亡率的相关性.
主要成果:
- 17%的MASLD患者是ANA阳性的,25%是ASMA阳性的.
- 组织学AIH特征存在于患者的一个子集中,可能的AIH在8%中被确定.
- 阳性ANA/ASMA独立预测了cACLD的发展,肝脏衰竭和死亡,而孤立的组织学特征没有影响预后.
结论:
- 自体抗体 (ANA,ASMA) 在MASLD中普遍存在,并与与肝脏相关的不良结果和生存率降低有关.
- 在MASLD中孤立的组织性自身免疫特征并没有赋予额外的预后价值.
- 识别具有阳性自身抗体的患者可以有助于对MASLD管理的风险分层.

Myasthenia Gravis: Overview and Treatment
2.8K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Autoimmune Disorders
1.5K
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.
