Results from this study indicated patients who had psoriatic arthritis and coexisting fibromyalgia had poor scores on all tested measures.
Researchers enrolled 73 patients with psoriatic arthritis (PsA) to participate in a prospective cross-sectional study. Investigators used American College of Rheumatism criteria to determine fibromyalgia. They conducted clinical evaluations for all patients which included disease activity with the Health Assessment Questionnaire (HAQ), the Bath Ankylosing Spondylitis Disease Activity Index, the Dermatology Life Quality Index (BASDAI) and the Leeds Enthesitis Index (LEI). The Composite Psoriatic Disease Activity Index (CPDAI), minimal disease activity and Disease Activity Index for Psoriatic Arthritis (DAPSA) scores were also used to evaluate disease activity.
Findings showed the prevalence of fibromyalgia overall was 17.8%. Patients with coexisting PsA and fibromyalgia had significantly higher CPDAI and DAPSA scores compared with patients who only had PsA. Investigators noted none of the patients with both fibromyalgia and PsA met minimal activity disease activity criteria; however, 26 patients with only PsA did meet the criteria.
According to researchers, patients with PsA and correlated fibromyalgia had significantly worse HAQ, BASDAI and LEI scores. ‒ by Monica Jaramillo
