Prevalence and Predictors of Achieving Sustained Remission in Psoriatic Arthritis: A Swedish Nationwide Registry Study
Authors' conclusion
A considerable proportion of patients with PsA receiving various b/tsDMARDs never achieved remission, and approximately half never achieved SR in this Swedish nationwide registry study.
Study context
- Population
- Patients with PsA initiating b/tsDMARDs registered in the Swedish Rheumatology Quality Register (SRQ), April 1999 to December 2019
- Participants
- 4,669 patients48,773 visits
- Outcome
- Sustained remission (SR): DAS28-CRP ≤ 2.6, DAPSA28 ≤ 4 or PGA = 0 persisting during ≥ 2 consecutive visits for ≥ 6 months
Methodological detailsnationwide registry, logistic regression
- Nationwide registry
- Logistic regression
Main finding
As reported in the abstract
- DAS28-CRP remission ever
- 81%
- DAS28-CRP sustained remission (SR) at least once
- 54%
- DAPSA28 remission ever
- 46%
- DAPSA28 SR
- 24%
- PGA remission ever
- 69%
- PGA SR
- 38%
Observational data: associations, not effects.
Further findings
- Male sex a positive predictor of SR by DAPSA28 and PGA but not by DAS28-CRP
- Fewer swollen joints at baseline predicted SR according to all 3 remission criteria
