Resumen
MONTANER RAMON, A. et al. Brain natriuretic peptide as a marker of digestive evolution in the premature newborn. Nutr. Hosp. [online]. 2019, vol.36, n.2, pp.261-266. Epub 27-Ene-2020. ISSN 1699-5198. https://dx.doi.org/10.20960/nh.2178.
Background and objective:
hemodynamically significant patent ductus arteriosus (HS-PDA) is associated with an increased risk of necrotizing enterocolitis (NEC) and worse enteral tolerance in preterm newborns (PN). An association has been demonstrated between brain natriuretic propeptide (proBNP) and HS-PDA. Our objective was to analyze the relationship between proBNP levels and enteral tolerance, NEC risk and weight gain in PN.
Material and methods:
a retrospective study was performed in neonates born before 32 weeks' gestation or with birth weight below 1500 grams, in whom proBNP determination and echocardiography were performed at 48 to 72 h of life.
Results:
117 patients were included. 65.8% had a HS-PDA and 9.4% had an outcome of NEC. HS-PDA was associated with longer duration of parenteral nutrition (p < 0.001), a confirmed NEC (p = 0.006) and worse weight gain during admission (p < 0.001). ProBNP levels were associated to NEC (no NEC 12189.5 pg / mL, range 654-247986; NEC 41445 pg/mL, range 15275-166172, p < 0.001). No association was found with the rest of gastrointestinal outcomes. Multivariate logistic regression analysis showed a significant association of NEC with gestational age and proBNP above 22,400 pg/mL (OR 13,386, 95% CI 1,541-116,262, p = 0.019).
Conclusions:
proBNP could be an early marker of severe digestive pathology in PN. Increased proBNP levels could be associated with a significant increased risk of NEC in very immature newborns.
