Key clinical point: In patients with psoriasis, the German Psoriasis Arthritis Diagnostic (GEPARD) questionnaire followed by a dermatological assessment can detect psoriatic arthritis (PsA) risk almost accurately, and entheseal ultrasound by dermatologists shows no additional benefits in this regard.
Major finding: PsA was diagnosed in 6 out of 40 patients, with a sensitivity of 100%; however, dermatologic ultrasound evaluation of the entheses alone was unable to confirm these findings. Of the remaining 34 patients with psoriasis, 8 were deemed by dermatologists as possibly having PsA based on the ultrasound examination although rheumatologists detected ultrasound abnormalities in only 3 patients.
Study details: Findings are from a cross-sectional study including 40 patients with psoriasis who completed the GEPARD questionnaire and subsequently underwent an assessment for PsA by a dermatologist and an ultrasound examination.
Disclosures: This study was supported by a conditional research grant from Rheumazentrum Erlangen-Nuremberg e.V. and AGJR Verbundprojekt. The authors declared no conflicts of interest.
