Abstract
STUDY OBJECTIVES: Although previous studies suggested an increased prevalence of obstructive sleep apnea (OSA) among patients with rheumatoid arthritis (RA), no existing large prospective study has addressed this association using objective measures. This study aims to assess the prevalence of OSA using polysomnography (PSG) in patients with RA and its relationship with RA activity. METHODS: Patients with RA who presented at the rheumatology clinic at a university hospital from 2017 to 2018 were eligible. In the first stage, data from the Disease Activity Score 28, Berlin questionnaire, and Epworth Sleepiness Scale were obtained, along with personal data and a comprehensive medical history. The second stage involved a case-control study confirming OSA with PSG. OSA was defined as an apnea-hypopnea index (AHI) ≥ 5 events/h, whereas patients with an AHI ≥ 15 events/h were categorized as having moderate-severe OSA. RESULTS: In total, 199 patients with RA were recruited, 110 patients (55%) underwent PSG, and 5 were excluded. The mean age was 48.93 ± 12.7 years, and the mean body mass index was 31.70 ± 9.74 kg/m²; 94% were female. In total, 67 participants (33.2%) were at high risk for OSA (36 [55.4%] underwent PSG), whereas 132 (66.8%) were at low risk (69 [51.5%] underwent PSG). The estimated prevalence of OSA (AHI ≥ 5 events/h) in the whole population was 58.1%, whereas the prevalence of moderate-to-severe OSA (AHI ≥ 15) was 22.9%. CONCLUSIONS: This prospective PSG-based study demonstrated that OSA is more common in patients with RA than in the general population, but there appears to be no relationship with disease activity.
