Prevalence and characteristics of gastroesophageal reflux in children with otitis media in Isfahan, Iran


Department of Otorhinolaryngology, Isfahan University of Medical Sciences, Isfahan, Iran


Background: Otitis media (OM) is the most common cause of childhood hearing loss and reason to visit the pediatrician. Furthermore, gastroesophageal reflux (GER) has been associated with a variety of upper aerodigestive tract symptoms or diseases, such as sinusitis, laryngitis, and otits. The objective of the present study was to determine the frequency of GER in children, aged 3 months to 7 years, with OM.
Materials and Methods: This retrospective case-control study was conducted on 50 children with OM and 50 healthy children. Presence of GER as the main variables was diagnosed by clinical examination in all studied children using the questionnaires with 2 age-stratified versions of the pediatric GER disease symptoms for children 2 years old and younger, and children 3–7 years old.

Results: The prevalence of GER in children with OM and controls was 58% and 22% respectively (P = 0.0005). The frequency of irritability, congestion, and feeding complex in children with OM were significantly more than in control groups. Among children with recurrent acute OM (AOM), and chronic serous OM (CSOM) the prevalence of GER was significantly more than controls (61.1%, vs. 22% for AOM, P = 0.004, and 72.7% vs. 22%, P= 0.003). In children with AOM, regurgitation, vomiting, irritability and congestion were significantly higher than controls included. In children with CSOM, regurgitation, vomiting, and congestion were significantly higher than controls.
Conclusion: Results show a significant association between GER and OM, AOM and CSOM in children with OM compares to healthy children. This shows that looking for GER in children with OM may help improving treatments outcomes.
