Developmental Changes in Soluble CD40 Ligand - 07/03/14

Résumé |
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.
