RESUMEN

OBJECTIVE: To compare the association of the severity categories of the 2001-National Institutes of Health (NIH), the 2018-NIH and the 2019-Jensen bronchopulmonary dysplasia (BPD) definitions with neurodevelopmental and respiratory outcomes at 2 and 5 years' corrected age (CA), and several BPD risk factors. DESIGN: Single-centre historical cohort study with retrospective data collection. SETTING: Infants born between 2009 and 2015 at the Amsterdam University Medical Centers, location Amsterdam Medical Center. PATIENTS: Preterm infants born at gestational age (GA) <30 weeks and surviving up to 36 weeks' postmenstrual age. INTERVENTIONS: Perinatal characteristics, (social) demographics and comorbidities were collected from the electronic patient records. MAIN OUTCOME MEASURES: The primary outcomes were neurodevelopmental impairment (NDI) or late death, and respiratory morbidity at 2 and 5 years' CA. Using logistic regression and Brier scores, we investigated if the ordinal grade severity is associated with incremental increase of adverse long-term outcomes. RESULTS: 584 preterm infants (median GA: 28.1 weeks) were included and classified according to the three BPD definitions. None of the definitions showed a clear ordinal incremental increase of risk for any of the outcomes with increasing severity classification. No significant differences were found between the three BPD definitions (Brier scores 0.169-0.230). Respiratory interventions, but not GA, birth weight or small for GA, showed an ordinal relationship with BPD severity in all three BPD definitions. CONCLUSION: The severity classification of three BPD definitions showed low accuracy of the probability forecast on NDI or late death and respiratory morbidity at 2 and 5 years' CA, with no differences between the definitions.

RESUMEN

INTRODUCTION: The objective of this study was to identify risk factors for neurodevelopmental impairment (NDI) at 2- and 5-years corrected age (CA) in a cohort of preterm infants with established bronchopulmonary dysplasia (BPD). METHODS: This single-center retrospective cohort study included infants born between 2009 and 2016 at a gestational age (GA) <30 weeks with moderate or severe BPD at 36 weeks' postmenstrual age. Perinatal characteristics, (social) demographics, and comorbidities were collected from the electronic patient records. Odds ratios for NDI were calculated with univariate and multivariate logistic regression analyses adjusting for potential confounders. RESULTS: Of the 602 eligible infants, 123 infants were diagnosed with BPD. NDI was present in 30.3% and 56.1% at 2- and 5-years CA, respectively. The only independent risk factors associated with NDI in the multivariate analyses were birthweight (adjusted odds ratio [aOR] 0.74, 95% CI 0.57-0.95; aOR 0.70, 95% CI 0.54-0.91, respectively), small for GA (SGA) (aOR 3.25, 95% CI 1.09-9.61; aOR 5.44, 95% CI 1.62-18.2, respectively) at both time points, and male gender at 5-years CA (OR 2.49, 95% CI 1.11-5.57). CONCLUSION: Birthweight and SGA are independent risk factors for NDI at 2- and 5-years CA and male gender at 5-years CA in preterm infants with BPD. In contrast, well-known other risk factors for NDI in the general population of preterm infants, such as GA, maternal education, and neonatal comorbidities were not independently associated with NDI.

RESUMEN

OBJECTIVE: To evaluate the association between bronchopulmonary dysplasia (BPD) severity and risk of neurodevelopmental impairment (NDI) at 2 years and 5 years corrected age and to examine whether this association changes over time. STUDY DESIGN: This single-center retrospective cohort study included patients with a gestational age <30 weeks surviving to 36 weeks postmenstrual age, divided into groups according to BPD severity. NDI was defined as having cognitive or motor abilities below -1 SD, cerebral palsy, or a hearing or a visual impairment. The association was assessed using a multivariate logistic regression model analysis, adjusting for known confounders for NDI, and mixed-model analysis. RESULTS: Of the 790 surviving infants (15% diagnosed with mild BPD, 9% with moderate BPD, and 10% with severe BPD), 88% and 82% were longitudinally assessed at 2 years and 5 years corrected age, respectively. The mixed-model analysis showed a statistically significant increase in NDI at all levels of BPD severity compared with infants with no BPD, and a 5-fold increased risk in NDI was seen from 2 years to 5 years corrected age in all degrees of BPD severity. The strength of this association between NDI and BPD severity did not change over time. CONCLUSIONS: Increased BPD severity is associated with increased risk of NDI at both 2 years and 5 years corrected age. The absolute incidence of NDI increased significantly from 2 years to 5 years corrected age for all BPD severity categories, but this increased risk was similar at both time points in each category.

RESUMEN

UNLABELLED: To establish the validity of biochemical markers of metabolic bone disease (MBD) in preterm infants. CONCLUSION: There is insufficient evidence that any of the frequently used serum measurements are valid biochemical markers of MBD in preterm infants. Increased urinary calcium concentration may be a valid biochemical marker, but more research is necessary to confirm this.
