Key clinical point: Ultrasound assessment of entheses may help differentiate psoriatic arthritis (PsA) from fibromyalgia syndrome (FMS) as patients with PsA showed more frequent ultrasound changes both in gray scale (GS) and power Doppler (PD) mode than those with FMS.
Major finding: A higher proportion of patients with PsA vs. FMS was detected with ≥1 entheses in GS (P < .0001) and PD (P = .0033) mode, with GS and PD identifying changes in a higher proportion of PsA vs. FMS entheses (P < .0001 for both). Area under the curve values for GS and PD mode were 0.77 and 0.66, respectively, with 3.5 being the best cutoff GS score to discriminate PsA from FMS (sensitivity, 0.75; specificity, 0.63).
Study details: Findings are from a post hoc analysis of the cross‐sectional ULISSE study including 140 and 51 patients with PsA and FMS, respectively.
Disclosures: This study was funded by AbbVie Srl. Three authors declared being employees and shareholders of AbbVie, and some of the authors declared receiving consultancy fees and research support from several sources.
