Abstract

Abstract : Background: Sleep disorders are frequent feature of chronic rheumatologic diseases. They are reported in inflammatory diseases as well as in mechanical disorders but they are not systematically assessed by clinicians. It is necessary to identify the frequency and factors associated to sleep problems in order to reduce their impact on patient's quality of life. Objectives: We aim to describe the sleep pattern in inflammatory and mechanical chronic rheumatologic diseases and to assess factors associated with sleep disorders. Methods: We conducted a cross-sectional study during 1 year including Tunisian patients with chronic inflammatory rheumatism (rheumatoid arthritis: RA according to the criteria ACR 1987 and axial spondyloarthritis: AS according to modified NEW YORK criteria) and patients with mechanical disorders (chronic low back pain and primitive knee osteoarthritis). Sleep has been evaluated by the MOS-SS questionnary. For each group specific disease parameters were assessed at the same time of the administration of the questionnary. Results: We collected 120 patients with chronic inflammatory rheumatism (group 1) and 80 patients with mechanical disorder (group2). Group 1 was composed of 70 RA and 50 SPA including 65 women and 55 men. The average age was 46.95 [18.75]. Group 2 was composed of 40 chronic low back pain and 40 primitive knee osteoarthritis including 48 women and 32 men. The average age was 51.95 [18.82]. Sleep disorders were frequent in both groups, but they were more noticeable in Group 1 patients than Group 2 patients 53.68% vs 26.38% (p=0.00). Risk factors for sleep disorders in rheumatoid arthritis were disease activity (p=0.00) and functional impairment (p=0.00). In patients with spondyloarthritis, risk factors for sleep impairment were disease activity (BASDAI (p=0.00), ASDAS vs (p=0.00) et ASDAS CRP (p=0.00)) and impaired quality of life (p=0.00). The factors involved in sleep disorders in chronic low back pain was the reduced lumbar spine mobility assessed by the finger-to-ground distance (p=0.00) and the schober index (p=0.01) and functional impairment assessed by Eiffel questionnaire (p=0.00). In patients with knee osteoarthritis the Lequesne index (p=0.008), the knee extension limitation (p=0.00) and the radiological damage (p=0.004) were associated to sleep impairment. Conclusions: Our results illustrate the frequency of sleep disorders in chronic rheumatic diseases. They should not be under estimated in patients with mechanical disorders. A better control of the factors associated to sleep impairment for each disease should help promoting a better sleep quality in patients with chronic rheumatologic diseases.
