概括
扩展的抗林蛋白抗体 (ACPA) 配置文件更好地预测了类风湿性关节炎 (RA) 患者的治疗反应,比标准的抗CCP3水平更好地预测了开始使用生物药物的患者. 需要进一步的研究来完善这一点,以便选择特定的RA疗法.
科学领域:
- 类风湿病学 类风湿病学
- 免疫学 免疫学 免疫学
- 生物标志物发现发现
背景情况:
- 类风湿性关节炎 (RA) 治疗对生物药物的反应在患者之间存在显著差异.
- 确定生物治疗的预测生物标志物对于RA的个性化医学至关重要.
研究的目的:
- 调查扩展的抗原特异性抗林蛋白抗体 (ACPA) 档案是否能预测开始生物治疗的RA患者的治疗反应.
- 为了比较扩展ACPA简介与标准抗CCP3抗体水平的预测值.
主要方法:
- 一项前性,观察性RA队列研究包括生物素素和暴露患者,这些患者开始使用抗TNF,非TNF或阿巴切治疗.
- 测量了25种酸的抗原特异性ACPAs,并进行了主要成分分析 (PCA).
- 在6个月后,使用顺序回归分析了主要成分 (PC) 评分,抗CCP3水平和EULAR治疗反应之间的关联.
主要成果:
- 分析了1092名RA患者;68.5%的患者在6个月后获得了中度/良好的EULAR反应.
- 三个主要组成部分 (PC) 解释了ACPA变化的70%. PC1和PC2与治疗反应有显著的相关性 (OR分别为1.76和1.74).
- 扩展的ACPA配置文件,特别是PC1和PC2,与治疗反应的关联比抗CCP3抗体水平更强.
结论:
- 与当前的抗CCP3抗体测量相比,扩展的ACPA配置文件显示,与RA中的生物治疗反应的关联性更大.
- 进一步开发PCA方法是有必要的,以指导个人RA患者选择特定的生物药物.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
178
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
205
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
