Key clinical point: The composite ultrasonography scores showed a significantly greater value for assessment of disease activity than clinical scores in patients with psoriatic arthritis (PsA) with coexisting fibromyalgia syndrome (FMS).
Major finding: Patients with coexisting PsA and FMS vs those without FMS had higher scores for several disease activity indices, including Composite Psoriatic Disease Activity Index, Disease Activity for PsA, and PsA Disease Activity Score ( P less than .001). However, both groups had similar total ultrasonographic scores regardless of FMS ( P = .68). A significant association was observed between FMS and higher scores on clinical activity indices ( P less than .001) but not with the ultrasonography score.
Study details: The data come from a prospective study of 156 patients with PsA who were categorized into those with (n=42) and without (n=114) FMS.
Disclosures: No specific funding or conflicts of interest were reported.
