银屑病甲损害与亚临床指伸肌腱附着点炎的相关性研究

Correlation between nail psoriasis and subclinical extensor tendon enthesitis

目的:探讨银屑病患者甲损害与亚临床指伸肌腱附着点炎的关系。方法:对银屑病患者双手远端指间关节指伸肌腱及指甲进行高频超声检查。结果:共有96例银屑病患者纳入本次研究,其中伴有甲损害的银屑病患者45例,甲正常银屑病患者51例。甲损害组16例患者有亚临床附着点炎(35.5%),甲正常组5例有亚临床附着点炎(9.8%),差异有统计学意义(P<0.01)。结论:银屑病甲损害可以作为筛查亚临床指伸肌腱附着点炎的指征。

Objective： To explore the correlation between nail psoriasis and subclinical extensor tendon enthesitis in psoriasis. Methods： Extensor tendons at the distal interphalangeal joints and fingernails of both hands were detected by high frequency ultrasound in the patients with psoriasis. Results： A total of 96 psoriasis patients were included in this study： 45 patients with nail involvement and 51 patients without nail involvement. Sixteen patients(35. 5%） had subclinical enthesitis in the nail psoriasis group and five(9. 8%） had subclinical enthesitis in the normal nail group,with a significant difference(P〈0.01）. Conclusion： Psoriatic nail can be used as a sign for the screening of subclinical extensor tendon enthesitis.
