概括
较低的C-反应蛋白 (CRP) 值可以更好地识别活跃的轴性脊柱关节炎 (axSpA). 标准CRP水平对检测axSpA患者的高疾病活性不那么敏感.
科学领域:
- 类风湿病学 类风湿病学
- 临床生物标志物 临床生物标志物
- 炎症性疾病 炎症性疾病
背景情况:
- C-反应蛋白 (CRP) 是轴性脊柱关节炎 (axSpA) 的一个关键的炎症生物标志物.
- 目前的CRP值显示在检测活动axSpA.时的灵敏度较低.
- 需要更敏感的CRP切线来准确评估axSpA.
研究的目的:
- 确定最佳的C-反应蛋白 (CRP) 值,以区分轴性脊柱关节炎 (axSpA) 中的疾病活性状态.
- 评估axSpA患者不同CRP水平的敏感性和特异性.
主要方法:
- 分析了200名轴性脊柱关节炎 (axSpA) 患者 (有/没有生物治疗).
- 尤登指数确定了歧视性的CRP门.
- 接收器操作特征 (ROC) 曲线分析评估了灵敏度和特异性.
主要成果:
- ≥0.25 mg/dl的CRP值有效地确定了高/非常高的疾病活动 (AUROC 0.71).
- 对于没有生物治疗的患者,最佳值是CRP≥0.35 mg/dl (AUROC0.72).
- 标准的炎症CRP值 (≥0.5 mg/dl) 表明检测高疾病活性的敏感性较差 (0.35).
结论:
- 建议使用低于标准的CRP切线值来更好地评估axSpA疾病活性.

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

01:20The JAK-STAT Signaling Pathway
8.6K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
