BACKGROUND: Several studies have demonstrated the association between chronic rhinosinusitis (CRS) and autoimmune diseases. However, there are few long-term longitudinal studies on this relationship. Therefore, we investigated the association between CRS and the risk of a subgroup of autoimmune disease using a representative nationwide cohort sample.
METHODOLOGY: We investigated the association between CRS and autoimmune diseases, including Sjögren’s syndrome, systemic lupus erythematosus, and ankylosing spondylitis. A total of 15,130 CRS patients and 30,260 patients without CRS were enrolled after 1:2 propensity score matching. A Cox proportional hazards model was used to analyse the hazard ratio (HR) of CRS for autoimmune disease.
RESULTS: The incidence of Sjögren’s syndrome, systemic lupus erythematosus, and ankylosing spondylitis was 0.55, 0.10, and 0.48 per 1000 person-years, respectively. Among autoimmune diseases, the risk of Sjögren’s syndrome in CRS patients was significantly increased to an adjusted HR (aHR) of 1.70, whereas we could not detect any significant risk of developing systemic lupus erythematosus or ankylosing spondylitis. In the subgroup analysis according to CRS phenotype, the adjusted HR of developing Sjögren’s syndrome was greater in CRS patients without nasal polyps) than in CRS patients with nasal polyps.
CONCLUSIONS: Our study suggests that CRS without nasal polyps is associated with an increased incidence of Sjögren’s syndrome diagnosis compared to CRS without nasal polyps. Additionally, there was no association between CRS and systemic lupus erythematosus or ankylosing spondylitis, regardless of CRS phenotype.
