ABSTRACT
A threshold of 50 µg fecal calprotectin per g stool sample (µg/g) is commonly used to diagnose chronic inflammatory bowel disease in adult patients and children over 4 years of age. In younger children, fecal calprotectin values are physiologically increased. For the first time, the objective of our study was to establish reference ranges in newborns for the measurement of meconium calprotectin with an automated assay (Liaison® XL, DiaSorin). A prospective study was conducted in 2022 in the Maternity Unit of the Clermont-Ferrand University Hospital, with the inclusion of full-term newborns without intestinal involvement. The quantitative automated Liaison® XL calprotectin assay was assessed on a panel of meconium samples. In our cohort of 132 term neonates, calprotectin values ranged from 21 to 855 µg/g of meconium (2,5th to 97.5th percentile) and the median value was 194 µg/g. In our cohort, only sex-related differences were observed for calprotectin values. No significant differences were found for the other factors studied (maternal or neonatal). Because of inter-individual variability, a sequential measurement of newborn calprotectin from meconium should be considered.
