BackgroundThe club cell 10-kDa protein (CC10) is a homeostatic protein that is produced in the lung, diffuses into the blood, and is then excreted into the urine and stool. CC10 is known to have anti-inflammatory properties and to have lower endogenous production in preterm infants.ObjectivesAs recombinant human CC10 (rhCC10) is being studied in preterm infants to reduce lung injury, understanding CC10 levels in term infants with normal lungs is needed to establish appropriate target dosing ranges.MethodsSerum, urine, and stool samples were collected from 24 healthy full-term infants, and CC10 levels were measured. Levels in term infants were then compared to those in preterm infants who were examined in our previous studies.ResultsThe mean gestational age and birth weight of the term infants were 38.8±1.1 weeks and 3,257±513 g, respectively. The mean gestational age of the preterm infants was 26.8±1.4 weeks. The median serum [CC10] levels with minimum and maximum values in term infants (214.2 ng/mL [34.1, 428.1]) were> 7-fold higher than in preterm infants (27.5 ng/mL [8.0, 760.0]; p< 0.05). A significant correlation was found between [CC10] in urine and stool as well as between gestational age and stool [CC10](p< 0.05).ConclusionsCC10 is detectable in serum, urine, and stool in healthy term infants, with levels significantly higher than in preterm infants. This provides important data for ongoing therapeutic intervention trials with rhCC10 in high-risk preterm infants.
