Insights
Infants with cystic fibrosis (CF) and mild airway inflammation experience disordered breathing and oxygen desaturation during sleep. This highlights the importance of monitoring respiratory status in young children with CF.
Area of Science:
- Pediatric Pulmonology
- Sleep Medicine
- Genetic Disorders
Background:
- Cystic Fibrosis (CF) is a genetic disorder affecting multiple organs, primarily the lungs.
- Early respiratory symptoms in infants with CF can be subtle, including rhinitis and cough.
- Sleep disturbances and oxygen desaturation are potential complications in pediatric respiratory conditions.
Purpose of the Study:
- To determine if children under 3 years with cystic fibrosis exhibit disordered breathing during sleep.
- To investigate the occurrence of nocturnal oxygen desaturation episodes in infants with CF.
- To assess the relationship between mild airway inflammation and sleep-disordered breathing in young CF patients.
Main Methods:
- Nineteen infants diagnosed with cystic fibrosis (mean age 13.1 months) and 20 healthy controls underwent overnight polysomnography.
- Respiratory function was assessed using pulse oximetry to measure oxygen saturation (SaO(2)).
- Comparison of sleep parameters and oxygen saturation levels between CF patients and controls.
Main Results:
- Seven out of 19 infants with CF showed signs of disordered breathing and oxygen desaturation during sleep.
- CF patients with active respiratory inflammation had significantly lower mean SaO(2) compared to controls.
- A higher percentage of total sleep time with SaO(2) below 93% was observed in symptomatic children with CF.
Conclusions:
- Infants and young children with cystic fibrosis and mild airway inflammation frequently experience nocturnal oxygen desaturation.
- Sleep-disordered breathing and hypoxemia may be present even with subtle respiratory symptoms in young CF patients.
- Findings underscore the need for vigilance regarding sleep quality and oxygenation in infants with CF.
Aim:
To investigate whether children with cystic fibrosis under 3 years of age have disordered breathing and episodes of oxygen desaturation during sleep.
Methods:
We studied 19 infants (9 boys and 10 girls) with cystic fibrosis, mean age 13.1 months (range 3-36 months) and 20 age and sex matched healthy subjects. Patients and controls underwent an overnight polysomnographic study and respiratory function testing on the following morning.
Results:
Seven patients with ongoing respiratory tract inflammation had disordered breathing and episodes of oxygen desaturation during sleep. Pulse oximetry showed a significantly lower mean oxygen saturation (SaO(2)) and a higher percentage of total sleep time spent with SaO(2) less than 93% in symptomatic children than in controls.
Conclusion:
Results suggest that infants and young children with cystic fibrosis and mild airways inflammation (rhinitis, cough, red throat) have episodes of oxygen desaturation during sleep.
