Issues relating to children born prematurely
1University Children's Hospital, Tübingen, Germany.
Insights
Premature infants face higher risks of respiratory issues, including wheezing and lung dysfunction. Early identification of risk factors and interventions are crucial for managing long-term respiratory health in these children.
Area of Science:
- Neonatal Medicine
- Pediatric Pulmonology
- Respiratory Medicine
Background:
- Premature infants have an elevated risk for acute and chronic respiratory disorders.
- Long-term respiratory morbidity, including symptomatic issues like cough/wheeze and lung function abnormalities, is reported in infants with chronic lung disease or severe bronchopulmonary dysplasia.
- No significant link between prematurity and classical atopic asthma has been established.
Purpose of the Study:
- To highlight the need for interventions targeting wheezing disorders and lung function abnormalities in prematurely born children.
- To emphasize the importance of identifying risk factors for long-term respiratory morbidity across different age groups.
- To guide future research and early intervention strategies for improved respiratory outcomes.
Main Methods:
- Review of existing literature on respiratory outcomes in preterm infants.
- Analysis of long-term respiratory morbidity and pulmonary dysfunction.
- Identification of potential risk factors affecting lung development and function.
Main Results:
- Preterm birth is associated with increased respiratory morbidity, including airflow obstruction and air-trapping.
- Symptomatic respiratory issues and abnormal lung function persist into later life.
- Classical atopic asthma is not significantly linked to prematurity.
Conclusions:
- Interventions should focus on reducing wheezing and improving lung function in preterm infants.
- Identifying risk factors affecting prenatal/postnatal lung growth, inflammation, infections, and environmental exposures is essential.
- Prospective studies are needed to identify major risk factors and inform prophylactic and therapeutic strategies.
Abstract:
Preterm infants suffer increased risk of acute and chronic respiratory disorders. In patients with chronic lung disease or severe bronchopulmonary dysplasia, long-term respiratory morbidity and pulmonary dysfunction into late childhood and early adulthood have been reported. This includes symptomatic morbidity (recurrent cough and/or wheeze) and lung function abnormalities such as increased resistance to airflow, airway hyperresponsiveness, and increased propensity to air-trapping. To date, no clinically significant association between prematurity and classical atopic asthma has been demonstrated. Therefore, interventions should primarily focus on the reduction of wheezing disorders and lung function abnormalities in children born prematurely. In order to design interventions in the foetal and early neonatal period or during childhood the potential risk factors for long-term morbidity need to be carefully identified at different age groups: factors which affect pre- and postnatal lung growth, airway inflammation, viral infections, air pollution and others. Future research issues should include well-conducted prospective follow-up programmes which will identify major risk factors in specific populations. Early intervention will provide information on disease mechanisms and on new prophylactic as well as therapeutic strategies.
