Insights
Soluble cluster of differentiation 14 (sCD14) in cord blood can predict wheezing and prolonged cough in infants. Higher sCD14 levels indicate an increased risk of developing these common respiratory issues by one year of age.
Area of Science:
- Pediatric Allergy and Immunology
- Biomarker Discovery
- Neonatal Health
Background:
- Soluble cluster of differentiation 14 (sCD14) is implicated in atopic symptom development, but prior research is inconsistent.
- The role of sCD14 as an early indicator of allergic conditions in infants requires further investigation.
Purpose of the Study:
- To assess the utility of cord blood sCD14 as a predictive biomarker for identifying allergy and respiratory symptoms in early childhood.
- To determine if sCD14 levels at birth can forecast the development of wheeze and prolonged cough by age one.
Main Methods:
- Enrollment of infants (0-1 year) from the Prediction of Allergies in Taiwanese Children (PATCH) birth cohort.
- Measurement of sCD14 concentrations in cord blood samples.
- Periodic pediatrician evaluations and questionnaire-based symptom tracking until 1 year of age.
Main Results:
- A cohort of 206 infants was analyzed.
- Cord blood sCD14 showed a positive association with wheeze and prolonged cough.
- Multivariate analysis identified cord blood sCD14 as the sole independent predictor for wheeze and prolonged cough, with increased levels correlating to higher risk.
Conclusions:
- Cord blood sCD14 emerges as a potential predictive biomarker for infant wheeze and prolonged cough.
- Elevated sCD14 levels at birth may signify an increased likelihood of developing these respiratory conditions within the first year of life.
Background:
Soluble cluster of differentiation 14 (sCD14) plays a role in the development and manifestation of atopic symptoms, although the results of previous studies have been inconclusive. The aim of this study is to evaluate the practical use of sCD14 as a predictive biomarker of allergy in young children.
Methods:
Children aged 0-1 year from a birth cohort in the Prediction of Allergies in Taiwanese Children (PATCH) study were enrolled. Cord blood sCD14 concentrations were measured. Pediatrician evaluation and questionnaire interviews were performed periodically until 1 year of age to determine the children's allergic and respiratory symptoms.
Results:
Two hundred and six 1-year-old subjects were enrolled. Wheeze was positively associated with cord blood sCD14, a family member with asthma and parental smoking. Prolonged cough was associated with cord blood sCD14, older maternal age and more siblings. In the multivariate logistic regression analysis, cord blood sCD14 was the only independent predictive biomarker for wheeze and prolonged cough by 1 year of age. Every 100-ng/ml increase in cord blood sCD14 resulted in a 1.56-fold higher risk of developing wheeze and a 1.62-fold higher risk of prolonged cough in children by 1 year of age.
Conclusions:
Cord blood sCD14 may be a useful biomarker for predicting infant wheeze and prolonged cough by 1 year of age.
