OBJECTIVE: To determine the sensitivity of the CASPAR criteria in patients with early psoriatic arthritis (PsA). METHODS: Consecutive patients with a clinical diagnosis of PsA and a disease duration < 12 months were enrolled for study. The proportion of patients meeting the criteria (i.e., the sensitivity) was determined. RESULTS: Forty-four patients with early PsA (23 women, 21 men; mean age 51 yrs, range 16-90) were enrolled. Mean disease duration (+/- SD) was 15.8 +/- 14.3 weeks (range 0.1-50.9 wks). Thirty-four patients satisfied the criteria at the first visit (sensitivity 77.3%). Most patients met the skin and laboratory criterion, i.e., they were rheumatoid factor-negative, while only 2 satisfied the radiologic criterion. CONCLUSION: Our findings suggest a less satisfactory performance of the CASPAR criteria when applied in early PsA. Lower sensitivity could mainly depend on the small proportion of patients fulfilling the radiologic criterion.
目的:确定CASPAR标准对早期银屑病关节炎(PsA)患者的敏感性。 方法:纳入临床诊断为PsA且病程<12个月的连续患者进行研究。确定符合标准的患者比例(即敏感性)。 结果:纳入44例早期PsA患者(23例女性,21例男性;平均年龄51岁,范围16 - 90岁)。平均病程(±标准差)为15.8±14.3周(范围0.1 - 50.9周)。34例患者首次就诊时符合标准(敏感性77.3%)。大多数患者符合皮肤和实验室标准,即类风湿因子阴性,而只有2例符合放射学标准。 结论:我们的研究结果表明,CASPAR标准应用于早期PsA时表现不太理想。较低的敏感性可能主要取决于符合放射学标准的患者比例较小。
