Sleep Quality in Patients with Spondyloarthritis: A Literature Review

Sleep quality has increasingly been recognized as an important component of health-related quality of life in patients with spondyloarthritis (SpA). Spondyloarthritis is a group of chronic inflammatory rheumatic diseases affecting the axial skeleton, peripheral joints, and entheses, often accompanied by extra-articular manifestations. The chronic and fluctuating nature of SpA is associated with persistent symptoms such as pain, stiffness, fatigue, and functional limitation. Evidence indicates that sleep disturbances are highly prevalent in patients with SpA and may occur across disease subtypes and stages. Impaired sleep quality has been associated with inflammatory activity, pain severity, psychological distress, and comorbid conditions, further contributing to overall disease burden. This literature review summarizes current evidence on sleep quality in spondyloarthritis, including fundamental aspects of sleep, the prevalence of sleep disturbance, commonly used assessment methods, and clinical factors related to impaired sleep. Recognition of sleep quality as a multidimensional patient-reported outcome may support a more comprehensive understanding of disease impact in patients with spondyloarthritis.
