The pathogenesis of obstructive sleep apnoea (OSA) in children remains uncertain. In this cross-sectional study, children with OSA and/or recurrent tonsillitis (RT) had similar prevalence of allergy, inflammation and obesity to healthy controls. Investigation of bacterial density in the nasopharynx, throat, adenoids and tonsils found high densities of non-typeable H. influenzae and S.aureus in tonsillar tissue in both OSA and RT associated with bacterial biofilm and higher densities in throat swabs compared to controls. Pathogen-specific serum and salivary antibodies were generally similar or higher in children with adenotonsillar diseases. Persistent bacterial infection appears important in both paediatric OSA and RT.
