Key clinical point: Age at onset of psoriatic arthritis (PsA) influences disease characteristics, with individuals developing PsA at older age having worse functionality and greater structural damage but a lower frequency of enthesitis and dactylitis.
Major finding: Patients with late vs early onset PsA showed greater structural damage (odds ratio [OR] 3.3; 95% CI 1.3-8.1), higher frequency of arthritis in upper limbs (OR 2.8; 95% CI 1.0-7.7), greater loss of functionality (OR 1.3; 95% CI 1.0-1.6), and lower frequency of enthesitis (OR 0.1; 95% CI 0-0.5) and sacroiliitis (OR 0.06; 95% CI 0-0.5).
Study details: This observational cross-sectional study included 231 patients with PsA with <10 years of disease duration from the REGISPONSER and RESPONDIA registries who were categorized into the early onset (≤40 years) or late onset (≥60 years) group depending on age at PsA symptom onset.
Disclosures: This study did not report the source of funding. The authors declared no conflicts of interest.
