Insights
History of viral infections, particularly lower respiratory infections, may increase the risk of pediatric obstructive sleep apnea (OSA). This suggests respiratory viruses might play a mechanical role in developing pediatric OSA.
Area of Science:
- Pediatric Pulmonology
- Infectious Diseases
- Sleep Medicine
Background:
- Obstructive sleep apnea (OSA) affects 1-5% of children, primarily linked to adenotonsillar hypertrophy.
- Respiratory viruses can persist in lymphoepithelial organs post-infection.
- The role of viral infections in pediatric OSA development requires further investigation.
Purpose of the Study:
- To systematically review the association between a history of viral infections and the risk of pediatric obstructive sleep apnea (OSA).
Main Methods:
- Systematic review of electronic databases (PubMed, Cochrane Library, Scopus) up to November 21, 2022.
- Inclusion of prospective or retrospective cohort studies comparing children with and without a history of viral infections.
- Data extraction and risk of bias assessment (ROBINS-I) by four independent reviewers.
Main Results:
- Four studies (one retrospective cohort, two prospective cohorts, one case-control) met the inclusion criteria from 1027 initially identified articles.
- Findings suggest a potential link between lower airway infections and subsequent pediatric OSA diagnosis.
Conclusions:
- Exposure to lower respiratory tract infections may precede pediatric OSA diagnosis.
- Respiratory viruses might contribute mechanically to the development of pediatric OSA.
- Further research is essential to elucidate the precise role of viral infections in pediatric OSA.
Abstract:
(1) Background: Obstructive sleep apnea (OSA) affects approximately 1% to 5% of children. To date, the main pathophysiological factor is adenotonsillar tissue hypertrophy. As many respiratory viruses can persist in secondary lymphoepithelial organs after upper airway infection, the objective of this systematic review was to investigate the link between history of viral infections and the risk of pediatric OSA. (2) Methods: Corresponding references were searched electronically (PubMed [MEDLINE], Cochrane Library and Scopus) until 21 November 2022. Prospective or retrospective cohorts, evaluating the children suffering from OSA with history of viral infections and comparing them with children with no history of viral infections written in English, were included. Four independent reviewers selected studies, extracted data, and evaluated the risk of bias using ROBINS-I. (3) Results: Of 1027 potentially eligible articles, four studies (one retrospective, two prospective cohorts and one case-control) were included. (4) Conclusions: Exposure to lower airway infections may precede the diagnosis of pediatric OSA suggesting that respiratory viruses may play a mechanical role in the development of pediatric OSA. Further research is required to improve our understanding of the role of viral infections. Registration: PROSPERO CRD awaiting.
