    Clinical scenario

    A 6-year-old boy with Down syndrome (DS) has presented to the community paediatric clinic with a history consistent with obstructive sleep apnoea (OSA). Clinical examination reveals that he demonstrates mouth breathing and that his tonsils are enlarged. His parents are keen to explore non-surgical options. Should montelukast be commenced?

    Structured clinical question

    In school-aged children with DS (patient), does montelukast (intervention) reduce the severity of OSA (outcome)?

    Search strategy

    A comprehensive literature review was carried out using PubMed and Web of Science in August 2022. The following terms were used:

    Title/Abstract: [leukotriene*]OR[montelukast]OR[anti-inflammatory]OR[anti inflammatory]

    AND

    Title/Abstract:[Trisomy 21]OR[Down syndrome]or[syndrome]

    AND

    Title/Abstract:[sleep disordered breathing]OR[sleep related breathing disorder]OR[obstructive sleep apnea/apnoea]

    This search revealed 93 results. Titles and abstracts were reviewed. 91 articles were removed for the following reasons: unrelated to the clinical question (n=63), non-systematic review articles (n=18), expert opinion or guidelines (n=2), protocol only for a systematic review (n=1) and excluded children with DS (n=7). Two studies were ultimately included and summarised in table 1. A review of the bibliographies revealed two further potential studies, but these were removed after full-text review due to lack of relevance to the clinical question.
