PHILADELPHIA — Despite frequent reports of poor sleep quality among patients with psoriatic arthritis, many do not receive treatment, according to findings from a cross-sectional study reported at ACR Convergence 2022.
“The purpose of this work is to evaluate the quality of sleep in patients with psoriatic arthritis and its relationship with clinical variable, activity, functionality, the impact of the disease, and emotional factors,” Marta Ibanez Martinez, a member of the rheumatology service at the University Hospital of Salamanca in Salamanca, Spain, said during the presentation.
The cross-sectional study included 247 patients who were diagnosed with PsA. The Peaceful Sleep Quality Index (PSQI) questionnaire was used to measure sleep quality.
The researchers reported that 63.15% of patients had poor sleep quality but, of these patients, 46.5% were not receiving treatment for insomnia. Worse sleep quality was seen among female patients who had a higher number of affected entheses, higher peripheral and axial activity, fatigue, anxiety or depression. According to the study, PSQI answers were related to functionality and impact of disease.
“Poor sleep quality was frequent in patients with psoriatic arthritis,” Martinez said. “Also, almost half did not receive any treatment.”
When analyzed through a multiple linear regression model, pain and fatigue (P < 0.001) contributed to 43% of the sleep pattern quality. When analyzed through a logistic regression, pain (OR = 1.2; 95% CI, 1.01 – 1.43), fatigue (OR = 0.89; 95% CI, 0.84 – 0.95), and anxiety (OR = 1.27; 95% CI, 1.06 – 1.51) contributed to 48% of poor sleep quality.
“Emotional factors were more relevant than inflammatory factors in relation to sleep quality,” Martinez said. “The cyclical relationship between sleep quality, emotional disorders and activity makes a multidisciplinary approach to the disease necessary.”
