概括
多生物标志物疾病活性 (MBDA) 评分,特别是高灵敏度C反应蛋白 (hsCRP),有助于诊断ACPA阴性年轻发病 (YORA) 和老年发病 (EORA) 患者的类风湿性关节炎 (RA). 这种组合为RA提供了宝贵的诊断见解.
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:
- 在老年人发病的类风湿性关节炎 (EORA) 中,抗素蛋白抗体 (ACPA) 的阳性性较低,可能是由于免疫衰变和疾病异质性.
- 精确诊断类风湿性关节炎 (RA) 是至关重要的,特别是在区分年轻发病的RA (YORA) 和EORA之间,以及在ACPA阴性病例中.
研究的目的:
- 评估多生物标志物疾病活动 (MBDA) 评分作为RA的诊断标志物,用于新出现关节症状的患者.
- 具体评估MBDA在ACPA阴性YORA和EORA患者中的实用性.
- 为了比较MBDA和hsCRP与ACPA在不同RA发病组的诊断性能.
主要方法:
- 在日本 (2018-2022) 两所机构对257名患有新发性关节症状的患者进行了回顾性研究.
- 基线血清样本分析MBDA和高灵敏性C反应蛋白 (hsCRP).
- 用灵敏度,特异性,准确性,AUC和逻辑回归来评估诊断性能.
主要成果:
- 在ACPA阴性YORA中,MBDA和hsCRP组合改善了诊断准确率至86.9%.
- 在EORA中,MBDA显示了比ACPA (70.1%) 更高的准确性 (74.9%).
- 在ACPA阴性EORA中,MBDA和hsCRP组合实现了最高的预测能力 (72.8%的准确性).
结论:
- MBDA评分,特别是与hsCRP结合使用时,为RA提供了显著的诊断价值.
- 这种综合方法对于在YORA和EORA患者组中诊断ACPA阴性RA特别有益.
- 在具有挑战性的RA病例中,MBDA作为一种有价值的替代或补充诊断工具.

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

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...

Genome-wide Association Studies-GWAS
15.9K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
