与异形性炎症性肌肉病变相关的抗Ha抗体,通常会出现肌肉损伤和皮肤病变. 虽然复发可能发生,但大多数患者在治疗后取得了良好的结果.
科学领域:
- 类风湿病学 类风湿病学
- 神经学 神经学
- 免疫学 免疫学 免疫学
背景情况:
- 异形性炎症性肌肉病变 (IIM) 是一组罕见的自身免疫性疾病.
- 肌肉炎特异性抗体 (MSA) 对于诊断和分类IIM至关重要.
- 抗Ha抗体是一种不太常见的MSA,其临床意义需要进一步阐明.
研究的目的:
- 描述具有抗Ha抗体的患者的临床,血清和组织病理特征.
- 评估抗Ha抗体阳性患者的治疗结果和长期预后.
- 确定IIM中抗Ha抗体的流行率和临床相关性.
主要方法:
- 对抗Ha抗体阳性患者的临床,血清和病理数据的回顾性分析.
- 使用免疫斑块和免疫沉技术识别和确认抗Ha抗体.
- 评估肌肉组织病理学,包括死亡和炎症的模式.
主要成果:
- 在570名IIM患者中,Anti-Ha抗体在3.0%的患者中被确定,其中29.4%与其他MSA共存.
- 肌肉损伤是主要的表现 (70.6%),在75%的病例中伴随着皮肤病变.
- 没有外周骨模式的瘤性肌病是主要的组织病理发现 (50%).
结论:
- 抗Ha抗体可能比以前认为的更为普遍,并且可以与其他MSA共存.
- 肌肉损伤是最常见的临床特征,而肌肉外参与是罕见的,除了皮肤表现.
- 尽管可能复发,但与抗Ha抗体相关的肌肉炎往往会显示出有利的长期结果.

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...
