概括
血清尿酸 (UA) 的升高预测了类风湿性关节炎 (RA) 患者的间歇性肺病 (ILD),尤其是年轻患者. 在RA-ILD患者中,UA升高也表明死亡率和再住院风险较高.
科学领域:
- 关节病学
- 肺病学
- 生物标志物发现
背景情况:
- 风湿性关节炎相关的间歇性肺病 (RA-ILD) 需要新的预测和预后生物标志物.
- 鉴定这些生物标志物对于患者的治疗和结果至关重要.
研究的目的:
- 研究 RA- ILD 患者血清尿酸 (UA) 的预测和预后意义.
- 评估UA在预测RA患者的ILD发展和结果中的作用.
主要方法:
- 一个多中心的回顾性队列研究包括829名RA患者,分为RA- ILD (n=351) 和RA- no- ILD (n=478) 组.
- 对ILD发生的预测能力进行了分析.
- 在RA- ILD患者中,全因死亡率和再住院率是次要终点.
主要成果:
- 通过多变量分析证实,血清UA升高是RA患者ILD发展的重要危险因素 (OR:1. 68;p=0. 001).
- 在没有并发症的年轻RA患者 (< 65岁) 中,亚组分析显示出更强的预测效用 (OR: 3. 66; p=0. 001; AUC: 0. 718).
- 患有高UA的RA- ILD患者的死亡率较高 (22. 1% 与 13. 1% 相比;HR: 1. 80;p=0. 040) 和再住院率较高 (51. 9% 与 44. 4% 相比;HR: 1.41;p=0. 047).
结论:
- 血清UA水平升高可作为ILD发病的预测标志物,特别是在没有并发症的年轻人中.
- 血清UA也是RA-ILD患者增加死亡率和再住院的预后指标.
- 这些发现突显了血清UA在治疗RA- ILD方面的潜在临床效用.

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
14.1K
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.
