Abstract

BACKGROUND
Psoriatic arthritis (PsA) is chronic seronegative inflammatory arthritis that causes irreversible joint damage. Early recognition of PsA in patients with psoriasis is important for preventing physical disability and deformity. However, diagnosing PsA in a busy dermatology outpatient clinic can be difficult.
OBJECTIVE
This study aimed to validate the Psoriatic Arthritis Screening and Evaluation (PASE) questionnaire for the detection of PsA in Korean patients with psoriasis.
METHODS
The PASE questionnaire was prospectively given to 148 patients diagnosed with psoriasis but without a previous diagnosis of PsA. All patients underwent radiologic and laboratory examinations, and a subsequent clinical evaluation by a rheumatologist.
RESULTS
Eighteen psoriasis patients (12.2%) were diagnosed with PsA according to the Classification Criteria for Psoriatic Arthritis. The PASE questionnaire scores of differed significantly between PsA and non-PsA patients. Receiver operator characteristic analysis showed an area under the curve of 0.82 (95% confidence interval: 0.72, 0.92) for PASE score. A PASE score cut-off of 37 points had a sensitivity of 77.8% and specificity of 82.3% for the diagnosis of PsA.
CONCLUSION
The PASE questionnaire is a simple and convenient screening tool for detecting PsA in Korean dermatology clinics. A PASE questionnaire score of 37 points appears to be an appropriate cut-off for screening Korean psoriasis patients.
