Key clinical point: Nailfold capillary abnormalities were more prevalent in patients with psoriatic arthritis (PsA) than in patients with psoriasis vulgaris (PsV) and predicted the development of PsA in patients with psoriasis.
Major finding: Nailfold bleeding (NFB; 84.5% vs 34.7%) and enlarged capillaries (100.0% vs 25.4%; both P < .0001) were more prevalent in patients with PsA vs PsV, with both NFB (hazard ratio [HR] 2.75; P = .004) and enlarged capillaries (HR 4.49; P < .0001) predicting the development of PsA in patients with PsV.
Study details: Findings are from a prospective cohort study including 236 patients with PsV and 213 patients with PsA.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
