Key clinical point: Nailfold capillaroscopy (NC) outcomes could not conclusively differentiate psoriasis from psoriatic arthritis (PsA).
Major finding: In addition to altered morphology, the density of capillaries at the nailfold was significantly lower in patients with psoriasis (standardized group difference [SMD] −0.91; P = .0058; area under curve [AUC] 0.740) and PsA (SMD −1.22; P = .0432; AUC, 0.806) compared with control individuals; however, no NC outcomes conclusively differentiated between psoriasis and PsA.
Study details: Findings are from a systematic review and meta-analysis of 22 studies investigating NC as a diagnostic tool for psoriasis or PsA.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
