title: PASE and EARP questionnaires for the identification of enthesitis, synovitis, and tenosynovitis in patients with psoriasis.
abstract: The aim of this study was to assess the diagnostic value of the Psoriatic Arthritis Screening Evaluation (PASE) and Early Psoriatic Arthritis Screening Questionnaire (EARP) questionnaires in the ultrasonographic detection of enthesitis, synovitis, and tenosynovitis. A cross-sectional study was done in a total of 96 consecutive patients. Double blind clinical examination and echographic assessment were performed. A receiver-operating characteristic (ROC) model analysis for the questionnaires was established using echographic findings as reference variable. The optimal diagnostic point was determined following a Youden analysis model from the obtained data, calculating sensitivity and specificity along with predictive values, likelihood ratio, and diagnostic odds ratio. A logistic regression analysis was used to determine possible predictor variables of enthesitis, synovitis, and tenosynovitis. When enthesitis, synovitis, and tenosynovitis were considered as one outcome for the diagnostic study of the PASE or EARP questionnaire, there were no statistically significant differences among the score of the study groups and the rest of patients. The PASE and EARP tests had a diagnostic performance for enthesitis, synovitis, and tenosynovitis that followed the expected pattern when the prevalence of findings is low. In these cases, the tests increase their negative predictive value, being particularly interesting in ruling out the disease.
