Calprotectin levels in meconium

Abstract

Calprotectin is already present in the first passed meconium, with higher levels in preterm and low birthweight neonates, as well as in neonates with some degree of perinatal asphyxia, as indicated by the negative correlation with 5'-Apgar score. These findings are probably secondary to both the immaturity of the intestinal mucosa and its hypoxic-ischaemic damage.
