Objective: To determine the prevalence of Helicobacter pylori infection in nasal biopsy specimens from patients with chronic rhinosinusitis with polyposis versus control patients, and to assess the correlations between H pylori infection identified in the nasal tissue and patients' sociodemographic data and reflux-related symptoms and signs.
Methods: Nasal biopsy samples were taken from 75 adult patients who underwent nasal surgery for chronic rhinosinusitis with polyposis (clinical group, n = 45) and a deviated septum (control group, n = 30). H pylori infection was identified using histochemical and rapid urease tests.
Results: The prevalence of intranasal H pylori infection was significantly higher in the clinical group (28.9 per cent) compared to the control group (3.3 per cent) (p = 0.005). A significant yet weak association was found between positive H pylori status and laryngopharyngeal reflux related hypertrophy of the posterior commissure of the larynx. No other correlations reached statistical significance.
Conclusion: H pylori infection is potentially related to chronic rhinosinusitis with polyposis. Further research is needed to clarify the role of H pylori as a risk factor for the development of sinonasal diseases and to examine its link with laryngopharyngeal reflux.
