Key clinical point: Patients with psoriatic arthritis (PsA) who had a personal history of psoriasis (pPsA) or a family history of psoriasis and current psoriatic lesions (fPsA/PSO) showed a higher disease activity (DA) and more severe axial joint destruction than those with merely a family history of psoriasis (fPsA).
Major finding: Patients with fPsA/PSO vs. fPsA had higher Disease Activity (DA) Index for PsA (DAPSA; 21.94 vs. 18.41; P = .046) and Bath Ankylosing Spondylitis DA Index (BASDAI; 4.09 vs. 3.74; P = .031) scores and more severe sacroiliitis (odds ratio [OR] 0.508; P = .037). The DAPSA ( P = .927) and BASDAI ( P = .716) scores were similar in patients with pPsA and fPsA/PSO.
Study details: Findings are from a prospective single-center, cross-sectional study including 296 patients with PsA, of which 145 had pPsA, 96 had fPsA, and 55 had fPsA/PSO.
