Spondyloarthritis & psoriatic arthritis

Comparative analysis of disease outcomes: Early vs. late transition from psoriasis to psoriatic arthritis

Semin Arthritis RheumPublished Prospective observational cohort study

Authors' conclusion

There were no significant differences in the PsA features at baseline between the two groups. However, on follow-up, there was a trend for lower cumulative disease activity but not in the rate of radiographic progression in the late transition group.

Study context

Population
Patients who developed psoriatic arthritis (PsA) after psoriasis, diagnosed with PsA prior to or at presentation to the clinic
Participants
702 patients
Exposure
Late vs early transition from psoriasis to PsA
Outcome
Disease activity: 5-year adjusted mean swollen joint count (SJC); damage: time to radiographic progression
Follow-up
5 years
Methodological detailsinception cohort (PsA duration ≤2 years), logistic regression, multivariate linear regression, Cox regression
  • Inception cohort (PsA duration ≤2 years)
  • Logistic regression
  • Multivariate linear regression
  • Cox regression

Main finding

As reported in the abstract

  • Trend for lower disease activity over time in the late transition group
  • Radiographic progression not significantly different

Observational data: associations, not effects.

Further findings

Baseline features of late transition

Younger age at psoriasis diagnosis and older age at PsA diagnosis in late transition
Higher BMI and PASI and less frequent csDMARD use at baseline in late transition
