异位淋巴新生和突组织中的特定炎症细胞透与类风湿性关节炎和牛皮性关节炎的预后不佳有关. 这些发现凸显了炎症性关节炎亚型的多样性病理影响.
科学领域:
- 类风湿病学 类风湿病学
- 免疫学 免疫学 免疫学
- 病理学 病理学 病理学
背景情况:
- 炎症性关节炎,包括类风湿性关节炎 (RA),牛皮性关节炎 (PsA) 和不分化关节炎 (UA),涉及慢性关节炎症.
- 尽管具有共同的致病机制,但RA,PsA和UA在疾病进展和严重程度方面可能具有不同的预后.
研究的目的:
- 在RA,PsA和UA患者中,研究突组织 (ST) 炎症细胞透,宫外淋巴新生 (LN+) 和不良预后因素 (PPF) 之间的关联.
主要方法:
- 一项回顾性研究通过关节镜检查或活检分析了88名患有活性关节炎 (RA,PsA,UA) 的患者的ST.
- 评估了临床,人口和免疫组织化学数据,但不包括接受生物治疗的患者.
- 根据RA,PsA和UA的特定标准定义了PPF,包括自身抗体,侵蚀和疾病活动标志物.
主要成果:
- 在RA患者中,LN+与PPF (p=0.038) 和生物疗法启动 (p=0.018) 相关.
- 在PsA患者中,CD15+透与PPF相关 (p=0.008).
- 在UA患者中,突CD68+巨细胞与DAS28-CRP (r=-0.346,p=0.042) 呈现负相关性,LN+和PPF之间没有发现关联.
结论:
- 同胞性LN+和CD15+多态核细胞透物分别与RA和PsA中的PPF有关.
- 没有发现UA的显著关联,这表明ST特征的异质性和炎症性关节炎亚型之间的病原性影响.

The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
