Low Postnatal Serum IGF-I levels is Associated with Bronchopulmonary Dysplasia (BPD).
(2012) In Acta paediatrica 101(12). p.1211-1216- Abstract
- Aim:
To characterize postnatal changes in serum IGF-I in relation to development of bronchopulmonary dysplasia (BPD) in very preterm infants.
Methods:
Longitudinal study of 108 infants with mean (SD) gestational age 27.2 (2.2) weeks. Weekly serum samples of IGF-I were analyzed from birth until postmenstrual age 36 weeks. Multivariate models were developed to identify independent predictors of BPD.
Results:
Postnatal mean IGF-I levels at postnatal day 3 to 21 were lower in infants with BPD compared to infants with no BPD (16 vs. 26 ug/L, p<0.001). Longitudinal postnatal change in IGF-I levels (IGF-I regression coefficient (β), postnatal days 3 to 21, was lower in... (More) - Aim:

Postnatal mean IGF-I levels at postnatal day 3 to 21 were lower in infants with BPD compared to infants with no BPD (16 vs. 26 ug/L, p<0.001). Longitudinal postnatal change in IGF-I levels (IGF-I regression coefficient (β), postnatal days 3 to 21, was lower in infants with BPD compared to infants with no BPD (0.28 vs. 0.97, p=0.002) and mean IGF-I during postmenstrual age 30-33 weeks was lower in infants with BPD as compared to infants without BPD (22 vs. 29 ug/L, p<0.001). In a binomial multiple regression model lower gestational age, male gender and lower mean serum IGF-I levels during postnatal day 3-21 were the most predictive risk factors associated with BPD (r(2) =0.634, p<0.001).
Conclusion:
Lower IGF-I concentrations during the first weeks after very preterm birth are associated with later development of BPD. © 2012 The Author(s)/Acta Paediatrica © 2012 Foundation Acta Paediatrica. (Less)
