AB1159 THE SPANISH VERSION OF THE PURE-4 QUESTIONNAIRE USE FOR PSORIATIC ARTHRITIS SCREENING AFTER 1 YEAR OF FOLLOW-UP IN PATIENTS WITH PSORIASIS

Background The Psoriatic arthritis UnclutteRed screening Evaluation (PURE-4), culturally adapted to Spanish language following the standardized methodology,[1] was recommended by experts due to the reduced number of items,[2] its high sensitivity/specificity and the feasibility to implement in clinical practice. Objectives To confirm the presence/absence of psoriatic arthritis (PsA) according to rheumatologist criteria in patients (pts) with psoriasis (Pso) 1 year after having answered the PURE-4 questionnaire in the dermatology consultation. Methods Cross-sectional, observational, multicenter study conducted with primary data collection under conditions of routine clinical practice in Spain. Adult pts (≥18 years old) with Pso diagnosis that voluntarily accepted to participate. Two cross-sectional evaluations. Assessment I allowed to validate the Spanish version of the PURE-4 questionnaire and its results were previously communicated.[3] Data from assessment II (pts without PsA in assessment I were evaluated by the rheumatologist 1 year ±2 months later and performed the PsA diagnostic confirmation according to her/his criteria and collected clinical characteristics) are presented here. Results 268 patients pts were included in assessment I, 223 (83.2%) of them without a PsA diagnosis. 219 pts were evaluable in assessment II, as they go to the second visit to rheumatologist: 56.2% male, with a mean (SD) age of 46.8 (12.5) years, a mean (SD) time from Pso diagnosis of 18.7 (12.8) years. Mean (SD) PURE-4 score was 2.4 (1.1) for pts with PsA and 1.2 (1.2) for pts without PsA diagnosis. Among pts who did assessment II, PsA diagnosis was confirmed in 12 (5.5%) pts. Area under the receiver-operating characteristic (ROC) curve was 0.7618 (95% CI: 0.6530, 0.8706) (n=217), confirming the good quality of the questionnaire (Figure 1). Using the Youden index, it was identified a score ≥2 indicative of a possible early presence of PsA, same as in assessment I. PURE-4 questionnaire showed a sensitivity of 75.0% and a specificity of 62.9%. In 63.6% of the cases, the PURE-4 questionnaire classified pts in the same way as the rheumatologist, with a negative predictive value of 97.7%. Conclusion Assessment II findings together with the assessment I results, demonstrate the good PsA screening properties of the PURE-4 questionnaire, starting with a ≥2 score, differing from the original questionnaire (≥1).[4] Questions of the PURE-4 questionnaire referring to dactylitis, both buttocks pain and peripheral joint pain with swelling (before age 50) were the most “discriminative” of PsA. The study reinforce the recommendation to assess annually, or ideally every 6 months, the possible PsA presence,[5] as early PsA identification thanks to simple tools such as PURE-4 could help to prevent irreversible joint damage of this disease.
