Abstract

Objective:

To investigate the role of local allergic inflammation and Staphylococcus aureus enterotoxins in chronic rhinosinusitis with nasal polyps.

Methods:

This study included 36 patients with chronic rhinosinusitis with nasal polyps and 18 controls. Total immunoglobulin E, eosinophil cationic protein, staphylococcal enterotoxin types A and B specific immunoglobulin E, staphylococcal enterotoxin types A and B, and myeloperoxidase levels were determined.

Results:

Four patients with chronic rhinosinusitis with nasal polyps had a local allergy. All chronic rhinosinusitis with nasal polyps patients tested negative for staphylococcal enterotoxin types A and B specific immunoglobulin E. The chronic rhinosinusitis with nasal polyps group had significantly elevated staphylococcal enterotoxin types A and B levels in the supernatant. Fourteen patients belonged to the eosinophilic chronic rhinosinusitis with nasal polyps group and the others were characterised as having non-eosinophilic chronic rhinosinusitis with nasal polyps.

Conclusion:

Local allergy may play a role in chronic rhinosinusitis with nasal polyps, independent of staphylococcal enterotoxin superantigens. Staphylococcal enterotoxins may be important in the pathogenesis of chronic rhinosinusitis with nasal polyps; however, their roles as superantigens were not confirmed in this study. In Chinese subjects, chronic rhinosinusitis with nasal polyps usually manifests as a neutrophilic inflammation.
