A review of the evidence confirms the importance of genetic risk in susceptibility to otitis media
Keywords: otitis media, level of evidence, genetic association, genetic susceptibility
What is already known about this subject:
- Otitis media, or inflammation of the middle ear, is a common disease in early childhood that can lead to hearing loss, speech delays and learning difficulties. Some children experience severe otitis media; some have recurrent bouts and others have episodes lasting more than three months.
- Genetic studies have identified a number of genes contributing to susceptibility to otitis media. This study reviews the genetic risk factors and limitations in published otitis media research in order to gain a ‘bigger picture’ view of the evidence and to provide suggestions for future studies.
What this Raine study adds:
- A review of the published literature investigating the genetic inheritance of otitis media confirmed the usefulness of genetic studies in identifying genetic risk factors contributing to otitis media in childhood.
- Future genetic studies need to include enough participants to ensure that genes with small effects are able to be detected.
- Despite the large body of research investigating the factors contributing to otitis media, lots more remains to be discovered.
