Objectives:
The aim of the study is to determine the presence of H. pylori in nasal polyps by both immunohistochemical staining with H. pylori antibody of biopsy specimens and enzyme-linked immunoadsorbent assay (ELISA) of sera.
Study Design:
A prospective, controlled, clinical trial.
Methods:
We enrolled 30 patients with nasal polyps and 20 controls with middle concha bullosa undergoing endoscopic sinus surgery (ESS). Blood samples of both the study and control groups were evaluated for anti-H. pylori specific immunoglobulin (Ig)G antibodies by ELISA. In addition, biopsy specimens of the removed polyps and the mucosal part of middle conchas were examined by the immunohistochemical analysis with H. pylori antibody.
Results:
In the blood samples, specific IgG antibodies to H. pylori were found in 26 (86.7%) of 30 polyp patients and 17 (85%) of 20 controls. In 6 (20%) of the 30 patients, H. pylori was identified in the nasal polyp tissue, but it was not detected in the mucosal part of the middle concha specimens. No significant statistical difference was observed for H. pylori antibodies by ELISA among the patients with nasal polyps and the control group (Fisher's exact test, P = .59). However, there was a statistical difference between the polyp biopsy specimens and the control biopsy specimens by immunohistochemical staining (Fisher's exact test, P = .037).
Conclusions:
This study indicates that H. pylori was found in increased prevalence in the nasal polyps. However, further controlled epidemiologic studies would be necessary to confirm our results and clarify the potential underlying pathogenetic mechanisms.
Insights
Helicobacter pylori (H. pylori) was found in a higher prevalence in nasal polyps compared to control tissues, suggesting a potential link. Further research is needed to confirm these findings and understand the role of H. pylori in nasal polyps.
Area of Science:
- Otolaryngology
- Microbiology
- Immunology
Background:
- Nasal polyps are inflammatory growths in the nasal cavity.
- The role of bacterial infections in the development of nasal polyps is not fully understood.
- Helicobacter pylori (H. pylori) is a bacterium commonly associated with gastrointestinal diseases.
Purpose of the Study:
- To investigate the presence of H. pylori in nasal polyps.
- To compare H. pylori prevalence in nasal polyps versus control nasal tissues.
- To evaluate the association between H. pylori infection and nasal polyposis.
Main Methods:
- A prospective, controlled clinical trial involving 30 patients with nasal polyps and 20 controls.
- Detection of anti-H. pylori specific immunoglobulin (IgG) antibodies in serum using enzyme-linked immunosorbent assay (ELISA).
- Immunohistochemical analysis of nasal polyp and control tissue specimens for H. pylori presence.
Main Results:
- H. pylori specific IgG antibodies were detected in 86.7% of polyp patients and 85% of controls via ELISA.
- H. pylori was identified in 20% of nasal polyp tissues but not in control tissues.
- Immunohistochemical staining showed a statistically significant difference in H. pylori presence between nasal polyps and control tissues (P = .037).
Conclusions:
- H. pylori infection appears to be more prevalent in nasal polyps than in healthy nasal mucosa.
- The findings suggest a potential association between H. pylori and the pathogenesis of nasal polyps.
- Further epidemiological studies are required to confirm these results and elucidate the underlying mechanisms.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
