Abstract:

Objective Circadian rhythm disorders links with autoimmune diseases. This study aims to explore the influencing factors for circadian rhythm disorders in patients with rheumatoid arthritis (RA) combined with insomni.Methods This was a multicenter cross-sectional clinical survey. Deputy chief physicians or above experienced in rheumatology were uniformly trained to collect relevant information through questionnaire surveys. The surveying questionnaire was designed from two dimensions of the insomnia severity index (ISI) and clinical information of RA patients. In 13 research centers in Hebei Province, RA outpatients or inpatients were screened according to inclusion and exclusion criteria. Relevant factors for insomnia in RA patients were compared and analyzed. Results A total of 181 RA patients were included in the analysis, including 60 (33.1%) with insomnia, and 121 without it. The male-to-female ratio was 1∶5. The average age of RA patients with insomnia was significantly older than those without insomnia (P<0.01). RA patients with comorbidities like hypertension, respiratory diseases, thyroid diseases, osteoporosis, or osteoarthritis had a significantly higher incidence of insomnia than those without comorbidities (P<0.05). RA patients taking traditional Chinese herbal medicine/ extracts of traditional Chinese medicine (TCM) had a significantly higher incidence of insomnia than those without TCM treatment (P=0.019). There was a significant difference in the incidence of insomnia among RA patients with varied disease activity scores and X-ray grading of hands (P<0.05). There were no significant differences in biochemical and immunological indicators between RA patients with or without insomnia (P>0.05). Conclusion A high proportion of RA patients suffer from insomnia, and the circadian rhythm disorder is associated with age, comorbidities, moderate-to-high disease activity, and radiographic grading.
