Key clinical point: The Disease Activity index for Psoriatic Arthritis (DAPSA) based on a quick quantitative C-reactive protein (qCRP) assay (Q-DAPSA) showed perfect agreement with conventional DAPSA in the majority of patients with PsA.
Major finding: Overall, 98.1% of patients were similarly categorized into disease activity groups (remission and low, moderate, and high disease activity) using Q-DAPSA and DAPSA, with both indices showing identical numerical values in 57.7% of patients.
Study details: Findings are from a multicenter, cross-sectional study including 104 patients with PsA and available CRP values (measured by routine laboratory and quick qCRP assays).
Disclosures: This study was partially supported by Novartis. The authors declared receiving grants, personal fees, or support for attending meetings and travels from Novartis and other sources.
