Key clinical point: Sleep disturbance was more prevalent in patients with psoriatic arthritis (PsA) than in those with psoriasis or healthy controls (HC) without inflammatory illnesses and was associated with various inflammatory and noninflammatory variables.
Major finding: Sleep disturbances were reported by 66.1% of patients with PsA vs. 45.0% of patients with psoriasis, and 15.0% of HC. Poor quality sleep was associated with tender points ( P = .017), pain ( P = .009), and global health scores ( P = .005) and could not be resolved by immunosuppressive medical therapy.
Study details: This cross-sectional study included 109 patients with PsA who initiated or switched treatment with conventional synthetic or biological disease-modifying antirheumatic drugs, 20 patients with psoriasis, and 20 HC .
