Summary

Obstructive sleep apnoea (OSA) in children is a prevalent sleep disorder, and is characterised by repetitive complete or partial upper airway obstruction during sleep. It is an important disease as it is associated with a large spectrum of end-organ morbidities.

Adenotonsillar hypertrophy is the commonest cause of OSA in children, however, the cause of the lymphoid tissue hypertrophy in some individuals but not the others remains unknown. To address the cellular heterogeneity and immune cell involvement in adenotonsillar hypertrophy, here, we propose to employ single-cell sequencing analysis to identify the cell-specific expression patterns associated with the disease, which will enhance our understanding of the pathogenesis of tonsillar hypertrophy in children with OSA and may provide directions for development of novel therapy.

Conditions

  • Obstructive Sleep Apnea of Child

Interventions

PROCEDURE

Tonsillectomy

Subjects who are diagnosed to have OSA with adeontonsillar enlargement will undergo adenotonsillectomy if it is clinically indicated. Adenotonsillar tissue will be obtained for single cell sequencing. Controls will be non-OSA subjects (with PSG OAHI \<1/hour) who undergo adenotonsillectomy for other reasons such as recurrent tonsillitis.
