Key clinical point: Patients with psoriatic arthritis (PsA) who had severe vs non-severe disease according to the modified Composite Psoriatic Disease Activity Index (mCPDAI) showed higher disease activity, experienced more pain, and had higher disease impact both at baseline and during follow-up.
Major finding: At baseline, 36.1% of patients had severe PsA as assessed by mCPDAI. A significantly higher disease activity, disease impact, number of tender or swollen joints, and pain and reduced function were observed in patients with severe vs non-severe disease at baseline and follow-up (all P < .01). Male sex and severity of skin involvement at baseline were the factors associated with the severe PsA at last follow-up (both P ≤ .01).
Study details: This retrospective analysis of a longitudinal study included 177 patients with peripheral PsA who were followed for at least 1 year.
