OBJECTIVES: To compare Helicobacter pylori prevalence rates in the nasopharynx of pediatric patients with and without otitis media with effusion (OME). STUDY DESIGN: Prospective, controlled. METHODS: The study group consisted of patients undergoing adenoidectomy for persistent OME. A control group of patients with no history of OME undergoing adenoidectomy was simultaneously enrolled. As a substudy, middle ear effusion samples were also analyzed for Helicobacter pylori. Polymerase chain reaction assays were run by using primers against the Helicobacter pylori gene. RESULTS: Helicobacter pylori was detected in the adenoids of 10 of 45 study group patients, and 6 of 37 controls (P = 0.49). Thirty-two percent of middle ear aspirates were positive for Helicobacter pylori. CONCLUSION: The current study confirms the presence of Helicobacter pylori in the nasopharynx and middle ear space, but our results do not support a role for this bacterium in the pathogenesis of otitis media with effusion.
