Ann Rheum Dis:尿酸控制预防无症状高尿酸血症患者痛风发作

2021-07-25 MedSci原创 MedSci原创

在无症状高尿酸血症和痛风患者中,将sUA控制在≤6.0mg/dL,可以减少痛风发作。

对于痛风患者,为预防痛风发作,目前普遍推荐的治疗目标为血清尿酸水平(sUA)≤6.0mg/dL。然而,对于无症状高尿酸血症尚未达成共识

近日,风湿病领域顶级期刊Annals of the Rheumatic Diseases上发表了一篇研究文章,研究人员使用日本健康保险索赔数据,探讨了控制sUA对预防无症状高尿酸血症患者痛风发作的潜在益处。


该回顾性队列研究分析了2012年4月至2019年6月期间JMDC索赔数据库,并确定了sUA≥8.0mg/dL的受试者,以及调查了受试者1年内的疾病状态(降尿酸治疗(ULT)处方、痛风发作、sUA)。研究人员通过2年或更长时间的疾病状态亚组来明确首次发作的时间和痛风发作的发生率,并使用多变量分析评估痛风发作和sUA控制之间的关系。

Kaplan-Meier曲线

 
该研究的分析人群由19261名符合纳入标准的受试者组成。研究人员发现,对于痛风和无症状高尿酸血症,接受ULT且sUA≤6.0mg/dL的患者比在sUA>6.0mg/dL或未接受ULT的患者痛风发作的发生率更低。对于首次痛风发作时间的Cox比例风险模型分析表明接受ULT的无症状高尿酸血症受试者(5.0<sUA≤6.0mg/dL)的HR最低,为0.45(95%CI为0.27至0.76),与未治疗的受试者(sUA≥8.0mg/dL)相比。
 
由此可见,在无症状高尿酸血症和痛风患者中,将sUA控制在≤6.0mg/dL,可以减少痛风发作。

Rheumatology:急性痛风发作时SUA水平下降原因与全身炎症反应相关

血清尿酸(SUA)水平在急性痛风发作时下降的原因尚不明确。有观点认为SUA水平的下降与全身炎症反应(SIR)相关,因SIR可促进尿尿酸的排泄。同时亦有观点认为,急性痛风发作时SUA的下降是由痛风病情本身引起的。针对以上分歧,来自英国伍尔弗汉普顿大学临床化学系的Jenna L. Waldron等人进行了一项前瞻性研究,研究结果发表于2013年4月的《风湿病学》(Rheumatology)杂志上。研究
