Sleep-Disordered Breathing in Duchenne Muscular Dystrophy: An Assessment of the Literature.

STUDY OBJECTIVES: The aim of this review is to review the literature on sleep-disordered breathing in Duchenne muscular dystrophy (DMD).

METHODS: PubMed was searched with an array of search terms, including "OSA," "obstructive sleep apnea," "sleep-disordered breathing," "muscular dystrophy," "neuromuscular," "Duchenne muscular dystrophy," "polysomnography," and "portable monitoring." All relevant articles were discussed.

RESULTS: Eighteen research articles and 1 consensus statement were reviewed, and assessed with relevant data presented. Three early studies prior to 1990 assessed DMD associated obstructive sleep apnea. Five studies assessed positive airway pressure (PAP) ventilation and/or sleep in varying neuromuscular disorders, including a cohort with DMD. Six studies since 2000 include PSG data in exclusively DMD cohorts. Three studies involved portable monitoring (PM).

CONCLUSIONS: PSG with transcutaneous CO2 capnography is an important part of the clinical care for those with DMD. The utility of PM in DMD is unclear with only 1 study to date comparing PSG to PM data. Initiation of PAP therapy using bilevel modality may prevent the need for device switching as the disease progresses.
