Abstract

OBJECTIVE: To explore whether fecal calprotectin (f-calprotectin, FC) may be an early marker for the identification of gastrointestinal injury in preterm infants by measuring FC concentration and changes of FC concentration in infants with different perinatal factors. METHODS: FC concentration was measured using ELISA in 76 samples (50-100 mg) obtained from 38 preterm infants (gestation 29 to 33 weeks), at birth and on the third day after birth (the 1st and the 2nd FC levels). The infants were classified into three groups according to the reason for preterm birth: premature rupture of membranes (PROM; n=13), spontaneous preterm birth (SPB; n=5) and indicated preterm birth (IPB; n=20). RESULTS: There were no significant differences between the 1st and 2nd FC levels in the 38 infants. The 1st FC level in the PROM group was significantly higher than that in the IPB group (P<0.05). The 1st FC level in infants whose mothers received antenatal antibiotics treatment was significantly lower. Infants born by cesarean section had a significantly lower 1st FC level than those born by vaginal delivery (P<0.05). Both the 1st and 2nd FC levels in infants with feeding intolerance were significantly higher than in infants with feeding tolerance (P<0.05). The 2nd FC level was negatively correlated with 1 min Apgar score (r=-0.3, P<0.05). CONCLUSIONS: Premature rupture of membranes and perinatal asphyxia may lead to an increase in the excretion of FC in preterm infants. FC may be used as a marker for early evaluation of gastrointestinal conditions in preterm infants.
