Atopy in chronic rhinosinusitis: impact on quality of life outcomes

Background

Chronic rhinosinusitis (CRS), in particular with nasal polyps (CRSwNP), has been linked with skewed T‐helper 2 and immunoglobulin E (IgE)‐mediated allergic responses. The role of atopy in CRS, however, remains unclear. Correlations between immunological allergic markers and patient‐reported outcomes measures (PROMs) were investigated.

Methods

A cross‐sectional study of adult patients with CRS undergoing endoscopic sinus surgery was conducted. Immunological allergic markers included automated immunoassay testing for serum‐specific IgE to common allergens (house dust mite, grass, mold, animal epithelia) and total IgE. PROMs were assessed using the 22‐item Sino‐Nasal Outcome Test (SNOT‐22). Patients were defined as atopic based on either a positive specific IgE or elevated total IgE (>160 kU/L).

Results

A total of 446 patients (45.7% female, age 49.05 ± 14.96 years) were recruited, of which 42.8% had asthma, 51.6% had CRSwNP, and 63.0% had eosinophilic CRS. Positive allergen sensitization was detected in 52.9% patients. Total IgE levels were elevated in 28.0% with mean IgE level of 161 ± 269 kU/L. Atopy was associated with younger age at the time of surgery, CRSwNP, asthma, and eosinophilic CRS (eCRS). Atopy was also associated with increased severity in nasal symptom score (13.1 ± 6.4 vs 11.9 ± 6.0, p = 0.04), as well as worse scores in the loss of smell/taste (χ2(1) = 5.97, p = 0.02) and need to blow nose (χ2(1) = 4.26, p = 0.04) questions in the CRS population. In the CRSwNP population, there was no significant association between atopy and PROMs.

Conclusion

Comorbid atopy in CRS is associated with additional symptom burden, reflected mainly within the nasal symptom quality of life markers. Atopy assessment in CRS is important to ensure appropriate and successful treatment of the disease.
