Hematological Indices Plus Ultrasound Can Detect Entheses in Patients With Psoriatic Arthritis

Key clinical point: Red cell distribution width (RDW) and mean platelet volume (MPV) can be used to detect enthesitis in patients with psoriatic arthritis (psoriatic enthesopathy) with musculoskeletal ultrasound scores.

Major finding: There was a significant association between clinical tenderness, presence of enthesophytes on plain radiography, and musculoskeletal ultrasound findings at entheses sites (P < .001 for each). RDW (P = .010) and MPV (P = .001) levels were elevated in patients with psoriatic enthesopathy vs control individuals without the disease, with the hematological indices being positively correlated with disease activity scores (P < .001).

Study details: This case-control study included 30 patients with psoriatic enthesopathy and 20 control individuals without the disease (age > 18 years).
