Objectives:
The objectives of the study were to determine the prevalence of chronic rhinosinusitis (CRS) overall and its 2 phenotypic variants, CRS with and without polyposis (NP), in patients with chronic inflammatory comorbidities including autoimmune disorders, inflammatory bowel disease, and atopic dermatitis. These findings were compared with data in patients with asthma. Patients with hypertension were also used as a reference group to estimate the incidence of CRS in a group with regular medical follow-up.
Study Design:
A retrospective, cross-sectional query of a large tertiary care electronic medical record database was performed.
Results:
Electronic medical record database prevalence of CRS in patients with hypertension was 4.4%. The prevalence of CRS was 18% in asthma (P < .0001), 7% in atopic dermatitis, 3.5% in inflammatory bowel disease, and ranged from 1.4% to 5.9% in autoimmune disorders. The frequency of CRS patients exhibiting the NP phenotype was similarly low in patients with autoimmune disease and hypertension, but was significantly greater in patients with asthma (P < .0001), inflammatory bowel disease (P = .033), and atopic dermatitis (P = .049),
Conclusions:
These findings suggest similar prevalence of overall CRS in patients with autoimmune disease and inflammatory bowel disease, and background rates as estimated by observations in hypertension patients. Inflammatory bowel disease and atopic dermatitis patients with CRS exhibit some skewing toward the NP phenotype, as do asthmatics, where this association is well known.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
