- Background/Purpose: Necrotizing enterocolitis (NEC) is highly associated with prematurity and is characterized by bowel necrosis and multi-organ failure. There is a strong need for improved diagnostic methods to reduce the significant morbidity and mortality associated with NEC. The aim of this single centre prospective study was to investigate the possibility to detect early signs of NEC, by using rectal intraluminal microdialysis and plasma intestinal fatty acid binding protein (I-FABP) in preterm infants admitted to a level III neonatal intensive care unit.Methods: The study was performed on extremely preterm infants with a gestational age of less than 28 weeks. During a 4-week period after birth, rectal intraluminal microdialysate levels of glucose, lactate, pyruvate and glycerol were measured, and plasma was collected for I-FABP analysis. Infants not developing NEC served as controls. Results: Microdialysis revealed signs of intestinal hypoxic or ischemic damage and cell membrane degradation, with a marked increase of both intraluminal glycerol and plasma I-FABP in infants developing NEC, as well as in infants suffering from other complications. The microdialysate levels of glucose, lactate and pyruvate were too low to be evaluated in this setting. All infants tolerated the microdialysis well without any complications.Conclusion: Elevated levels of intraluminal glycerol and plasma I-FABP suggests mucosal cell membrane degradation and hypoxic or ischemic damage in preterm infants developing NEC, as well as in preterm infants suffering from other complications such as volvulus, sepsis or respiratory distress. However, it was not possible to predict development of NEC before clinical diagnosis using these markers.
