Brief Summary

Apnea of prematurity is a common condition that is usually treated with methylxanthines. Methylxanthines are adenosine receptor blockers that have powerful influences on the central nervous system. However, little is known about the long-term effects of methylxanthines on the developing brain. The Caffeine for Apnea of Prematurity-Sleep (CAP-S) Study is a sub-study of the main Caffeine for Apnea of Prematurity (CAP) trial, an international placebo-controlled randomized trial of methylxanthine therapy for apnea of prematurity. This sub-study is designed to take advantage of this cohort of ex-premature, 5-7 year old children who were randomized at birth to receive either caffeine or placebo, and are currently receiving detailed neurocognitive and behavioral assessments in the CAP trial.

Outcome Measures

Primary Outcomes (3)

  • Aim 1: The primary outcome is the mean actual sleep time as measured by actigraphy, between subjects who received caffeine vs placebo.

    5-7 years

  • Aim 2: The primary outcome is the apnea hypopnea index (AHI) between subjects who received caffeine vs placebo.

    5-7 years

  • Aim 3: The primary outcome is the correlation between full-scale IQ from the Wechsler Preschool and Primary Scale of Intelligence (measured in the CAP trial rather than directly from this protocol), sleep time and AHI.

    5-7 years

Secondary Outcomes (2)

  • Questionnaire data: National Sleep Foundation (NSF) and Pediatric Sleep Questionnaire (PSQ) scores

    5-7 years

  • Polysomnography data: Sleep architecture, arousal index, central apnea index, SpO2 and periodic limb movement index.

    5-7 years

Study Arms (2)

caffeine

ACTIVE COMPARATOR
Drug: Caffeine citrate injection

placebo

PLACEBO COMPARATOR
Drug: placebo

Interventions

Loading dose: 20 mg/kg administered over at least 30 minutes via IV infusion or over at least 10 minutes via slow IV injection. Daily maintenance dose (to commence at least 24 hours after loading dose): 5 mg/kg, administered over at least 10 minutes via IV infusion, or over at least 5 minutes via slow IV injection. Maintenance dose to be adjusted for body weight every 7 days. If indicated, maintenance dose may be increased to a maximum of 10 mg/kg. May be given orally once full enteral feeds are established. Duration of treatment: discontinue after infant has tolerated at least 5 consecutive days without positive pressure support AND when the infant is judged by the attending clinician to be no longer a candidate for methylxanthine therapy.
