Key clinical point: Many patients with psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA) have impaired sleep despite treatment, with female patients having worse sleep quality than male patients.
Major finding: Overall, 46.6% of patients in the entire cohort had abnormal sleep behavior, with sleep quality being worse in women vs men (P < .001). Depressive symptoms (P < .001), female sex (P = .014), and Disease Activity Score in 28 joints (P = .003) predicted insomnia in PsA.
Study details: The data come from a retrospective medical chart analysis of 330 patients with spondyloarthritis, including 168 patients with PsA and 162 patients with axSpA.
Disclosures: This study was partly funded by an unrestricted grant from Novartis Pharma GmbH, Germany. Several authors, including the lead author, reported receiving speaker honoraria or research or travel grants or serving on advisory boards for several sources, including Novartis.
