The potential role of Helicobacter pylori in chronic rhinosinusitis with or without nasal polyposis

Abstract Background Certain gastrointestinal and extra-intestinal diseases are caused by the gram-negative bacterium Helicobacter pylori ( H. pylori ). We aimed to determine the potential H. pylori role in chronic rhinosinusitis (CRS) with or without nasal polyposis. This cross-sectional study was conducted on 80 subjects. Patients were further categorised into two equal groups: study group ( n = 40) were diagnosed with CRS with or without nasal polyposis (CRSWNP and CRSSNP) who had failed medical treatment and scheduled for surgery, and control group (40 patients) were admitted for septoplasty. All patients had clinical assessment, physical assessment, diagnosis of rhinosinusitis (according to EPOS), based on symptoms, rhinoscopic/endoscopic findings, CT scan findings, questionnaire for gastroesophageal reflux disease (GERD), and questionnaire for laryngopharyngeal reflux (LPR). Samples were collected in the operating room during surgery from both groups and PCR tissue was done. Results The study group patients demonstrated significantly higher history of GERD, LPR, and H. pylori . H. pylori patients had significantly lower ages than those without ( P = 0.03). Patients with H. pylori revealed significantly higher GERD history ( P < 0.001) and LPR ( P = 0.002) than those without H. pylori . History of GERD ( P = 0.003), LPR ( P = 0.043), and H. pylori presence ( P = 0.028) were significant predictors, controlling for the abovementioned variables. Conclusions We concluded that a significant correlation was observed between the H. pylori presence in the sinonasal mucosa and nasal polyps and the development of chronic rhinosinusitis with or without nasal polyps.
