Tracing of Helicobacter pylori in the middle ear and mastoid mucosa of patients under 18 years of age with chronic otitis media (with and without cholesteatomas)

It has been estimated that about 5 million people of those affected with otitis media have cholesteatoma, however, its pathophysiology is unclear. In this study we aimed to detect via polymerase chain reaction and real-time polymerase chain reaction in young patients with chronic otitis media. Patients included in our prospective cross-sectional study had middle-ear/mastoid inflammation and underwent surgical procedures. Middle-ear mucosa samples were collected, and genomic DNA was extracted for detection by polymerase chain reaction and real-time polymerase chain reaction analyses. Sociodemographic data and gastroesophageal reflux symptoms were analysed. We included 49 patients with mean age of 12.7 ± 3.8 years. Twenty per cent of the patients were diagnosed with cholesteatoma. No increase in -amplified fluorescence was observed, indicating absence of . Due to the absence of amplification for and the fact that albumin was amplified in all samples, we conclude that does not appear to be a causal factor.
