耐炎性类风湿性关节炎 (RA) 呈现不同的表型:持久性炎症性RA (PIRRA) 呈现活跃的炎症,而非炎症性RA (NIRRA) 则表现出具有非炎症性疼痛驱动因素的免疫/纤维组织学.
科学领域:
- 关节病学
- 免疫学
- 病理学
背景情况:
- 风湿性关节炎 (RA) 是一种慢性自身免疫性疾病,其特征是关节炎.
- 耐火性关节炎 (RA) 是一个治疗挑战,需要对其潜在病理有更深入的了解.
- 耐火性关节炎的不同临床表型可能会影响疾病机制和患者的结果.
研究的目的:
- 描述耐药性类风湿性关节炎 (RA) 的突病理.
- 为了比较两个假设的临床表型:持久性炎症耐药性RA (PIRRA) 和非炎症耐药性RA (NIRRA).
- 将这些表型与非耐火性RA (NORRA) 相比较.
主要方法:
- 在两个学术风湿病中心进行前性观察队列研究.
- 成年 RA 患者的超声导向突组织活检 (临床疾病活动指数> 10).
- 组织病理学评估,包括克伦综合炎评分 (KSS) 和免疫组织化学病型评估 (淋巴细胞,扩散细胞,乳腺免疫/纤维细胞).
主要成果:
- 与PIRRA相比,NIRRA患者的克伦综合炎分数 (KSS) 和淋巴细胞总量较低.
- 与PIRRA相比,NIRRA主要表现为一种免疫/ 纤维瘤病变型,具有较高的免疫/ 纤维瘤突炎的相对风险 (1.6).
- 尽管疾病活动得分相似,NIRRA患者报告疼痛明显增加,生活质量降低,这表明非炎症机制.
结论:
- 耐火性RA包括不同的突和临床表型.
- 持续性炎症耐药性RA (PIRRA) 具有活跃的突炎症和免疫细胞透的特征.
- 非炎症耐药性RA (NIRRA) 涉及免疫/纤维组织学和疾病负担的重要非炎症因素.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
