Abstract：
:Both early diagnostic and prognostic assessment of the acute abdomen in preterm infants are hampered by the lack of a sensitive and specific parameter for intestinal injury. In this prospective clinical study we wanted to estimate the value of intestinal (I-) and liver (L-) fatty acid binding protein (FABP) in diagnosing necrotizing enterocolitis (NEC). Using highly sensitive and specific sandwich ELISAs which employ recombinant human I- and L-FABP as standard proteins (limit of detection 0.1 ng/ml plasma), the L-FABP concentration (median 7.6 ng/ml) was determined to be about 3 fold that of I-FABP (median 2.52 ng/ml) in plasma of healthy preterm infants. I- and L-FABP concentrations significantly increased with birth weight (1.6 and 5.0 ng/ ml per kg, respectively). At onset of symptoms, I-FABP concentration was significantly higher in infants who later developed severe NEC compared to healthy infants and those, whose illness remained confined to stage I or II. L-FABP was significantly elevated compared to the control group at onset of symptoms regardless of the further course of NEC. In conclusion, I-FABP appears to be a specific parameter for early detection of intestinal injury leading to severe NEC stage III. L-FABP, however, is a promising sensitive marker even for stage I of NEC.
