Helicobacter pylori in allergic and non-allergic rhinitis does play a protective or causative role?

Purpose Many studies have investigated the effect of Helicobacter pylori ( H. pylori ) colonization on the development of allergic diseases, but with conflicting results. The purpose of this cross-sectional observation study is to estimate H. pylori prevalence in allergic and nonallergic nasal conditions and compare with normal population. Methods 274 patients were tested for H. pylori with stool antigen test. Patients were compared with the control group for H. pylori positivity rates after they were categorized according to their primary diagnoses as mite allergy, pollen allergy, mite and pollen allergy, and non-allergic rhinitis with eosinophilic syndrome (NARES). Results were also classified according to age. Results The number of H. pylori -positive patients with mite allergy, mite and pollen allergy, and NARES were significantly higher than the control group in sadults. The percentages of patients in the pediatric group who had mite allergy, pollen allergy, mite and pollen allergy, or NARES were not significantly different when compared to the control group. Conclusion Forthcoming studies would undoubtedly evaluate of the profits of treating allergic nasal conditions by treating the aforementioned bacterial infection.
