Increased parental perception of sleep disordered breathing in a cohort of infants with ALTE/BRUE events

BACKGROUND: An apparent life-threatening event (ALTE) describes an acute, unexpected change in an infant’s breathing, aspect, or behavior frightening to the parent or caretaker. According to the new recent terminology, clinicians should use the term Brief Resolved Unexplained Event (BRUE) to describe an event occurring in an infant <1 year of age when the observer reports a sudden, brief, and now resolved episode. The aims of the present study in infants were: to investigate sleep disturbances in both ALTE event and after their classification according the new BRUE criteria. METHODS: We enrolled (from April to May 2016) 32 consecutive infants referred to our ambulatory for sleep disorders for follow-up after an ALTE episode and 32 pair healthy controls. We administered to parents the adapted questionnaire “Sleep Disturbance Scale for Children –SDSC”. RESULTS: Among enrolled infants with ALTE, there were 26 infants in line with the new BRUE definition, of which 10 at low risk and 16 at the high-risk event. CONCLUSIONS: Infants with ALTE and BRUE had more referred-by-parents’ sleep symptoms than controls. In particular, sleep disordered breathing wa prevalent in both, requiring a longer follow-up for this disturbance.
