Insights
Soluble CD40 ligand (sCD40L) levels are highest in neonates and remain elevated throughout childhood compared to adults. Age-specific reference ranges are crucial for evaluating sCD40L in pediatric conditions.
Area of Science:
- Immunology
- Pediatric Health
- Biochemistry
Background:
- Soluble CD40 ligand (sCD40L) plays a role in immune responses.
- Understanding age-related variations in sCD40L is important for clinical interpretation.
Purpose of the Study:
- To investigate age-dependent changes in sCD40L levels.
- To establish reference ranges for sCD40L in healthy pediatric and adult populations.
Main Methods:
- sCD40L was quantified using enzyme-linked immunosorbent assay (ELISA).
- Participants included neonates, children (3 months-15 years), and adults.
- Statistical analyses included Mann-Whitney tests and correlation coefficients.
Main Results:
- Plasma sCD40L levels were significantly higher in neonates and pediatric groups compared to adults.
- No significant differences were observed between pediatric age subgroups.
- Serum sCD40L was highest in neonates but showed no significant difference between pediatric and adult groups.
Conclusions:
- Plasma sCD40L levels exhibit a developmental trajectory, being highest at birth and remaining elevated through childhood.
- Further research is needed to elucidate the reasons for these developmental changes.
- Establishing age-appropriate reference ranges for sCD40L is recommended for pediatric evaluations.
Objectives:
To determine if soluble CD40 ligand (sCD40L; formally CD154) levels vary with age and to identify age-dependent ranges in healthy pediatric and adult populations.
Study Design:
sCD40L was measured in 25 neonates, 74 children (3 months-15 years of age) and 20 adults using an enzyme-linked immunosorbent assay. For age group comparisons, Mann-Whitney tests were performed. Correlation coefficients assessed relationships between plasma and serum sCD40L.
Results:
Plasma sCD40L levels were higher in neonates than in all other age groups, (P <.001). All grouped pediatric plasma levels were significantly higher than in adults (P < .0001). There were no significant differences in plasma sCD40L between pediatric age groups. Serum levels were significantly higher in neonates than in any other age group (P < .0001). Pediatric and adult serum sCD40L levels were not significantly different.
Conclusions:
Plasma sCD40L levels are highest at birth and remain higher than those in adults throughout childhood. Reasons for such developmental changes remain to be investigated. Age-appropriate reference ranges should be used when sCD40L is being evaluated in pediatric disorders.
