Prevalence of Fibromyalgia and Widespread Pain in Psoriatic Arthritis: Association With Disease Severity Assessment in a Large US Registry
Authors' conclusion
FM prevalence is elevated in PsA and is associated with elevated disease measures, confounding reliable disease assessment for treat-to-target goals.
Study context
- Population
- Patients in the CorEvitas psoriatic arthritis (PsA) registry completing the Widespread Pain Index (WPI)/Symptom Severity Scale (SSS) questionnaires since May 2020, at their most recent visit
- Participants
- 1,823 patients
- Exposure
- PsA patients with fibromyalgia (FM) vs without FM
- Outcome
- Prevalence of FM and widespread pain (WPI and SSS questionnaires)
Methodological detailsregistry-based
- Registry-based
Main finding
As reported in the abstract
Fulfilled the FM definition
11.1%
Fulfilled the widespread pain (WP) definition
20.6%
Observational data: associations, not effects.
Further findings
Factors associated with the FM definition
- Female sex, depression and/or anxiety, impaired function, increased BMI and increased number of comorbidities were associated with FM
Disease activity measures (Clinical Disease Activity in Psoriatic Arthritis (cDAPSA), patient pain and global assessment, tender joint count)
- Twice as severe in patients with FM compared to those without
