Intraventricular Hemorrhage in Very Preterm Children: Mortality and Neurodevelopment at Age 5.

ABSTRACT:

Objectives

The objectives were to describe mortality and causes of death in children with intraventricular hemorrhage (IVH) and to study neurodevelopmental outcomes.

Methods

The study was a secondary analysis of the French national prospective and population-based cohort EPIPAGE-2. Children were recruited in 2011. A standardized assessment was conducted at age 5. Children born before 32 weeks' gestation and admitted to a NICU were eligible. Exposure was IVH defined by the Papile classification. Main outcomes were mortality, causes of death, and neurodevelopmental outcomes at age 5.

Results

Among the 3468 children included, 578 (16.7%) had grade 1 IVH, 424 (12.2%) grade 2 IVH, and 114 (3.3%) grade 3 IVH; 144 (4.1%) had intraparenchymal hemorrhage (IPH). Mortality was 29.7% (36 of 114) for children with grade 3 IVH and 74.4% (109 of 144) for those with IPH; 67.6% (21 of 31) and 88.7% (86 of 97) of deaths, respectively, were because of withholding and withdrawing of life-sustaining treatment. As compared with no IVH, low-grade IVH was not associated with measured neurodevelopmental disabilities at age 5. High-grade IVH was associated with moderate and severe neurodevelopmental disabilities, reduced full-scale IQ, and cerebral palsy.

Conclusions

Rates of neurodevelopmental disabilities at age 5 did not differ between children without IVH and those with low-grade IVH. For high-grade IVH, mortality rate was high, mostly because of withholding and withdrawal of life-sustaining treatment, and we found a strong association with overall neurodevelopmental disabilities in survivors.

Project description:ImportanceNeurodevelopmental outcomes of very preterm children exposed to tocolytics are not well described.ObjectiveTo investigate whether tocolysis administered after spontaneous preterm labor is associated with neurodevelopmental outcomes at 5.5 years and to assess whether the type of tocolytic drug is associated with neurodevelopmental outcomes among infants exposed.Design, setting, and participantsThis prospective, national, population-based cohort study used data from the French Etude Épidémiologique sur les Petits Âges Gestationnels-2 cohort. Children who were alive and participated in an assessment at 5.5 years and whose mothers experienced spontaneous preterm labor without an infectious context and delivered at 24 to 31 weeks were eligible for this study. Recruitment occurred from March to December 2011. Follow-up at age 5.5 years was conducted from September 2016 to December 2017. Data analysis was performed from July 2023 through April 2024.ExposuresThe primary analysis examined tocolytics (yes vs no), and the secondary analysis examined the type of tocolytic (atosiban vs calcium channel blockers [CCBs]).Main outcome and measureThe composite outcome neurodevelopmental disabilities included cerebral palsy; visual, hearing, and cognitive deficiencies; developmental coordination disorders; or behavioral problems.ResultsA total of 1055 mothers (mean [SD] age, 29.2 [5.7] years) had preterm labor without fever and gave birth to 1320 children (704 male [weighted percentage, 53.3%; 95% CI, 50.6%-56.1%]; mean [SD] gestational age, 28.8 [2.0] weeks). Overall, 776 mothers (weighted percentage, 73.5%; 95% CI, 70.8%-76.2%) received tocolytics; 136 mothers (weighted percentage, 17.9%; 95% CI, 15.3%-20.8%) received only a CCB, and 295 mothers (weighted percentage, 37.6%; 95% CI, 34.2%-41.0%) received only atosiban. From modified Poisson regression with propensity score matching, the risk of overall neurodevelopmental disabilities (mild, moderate, or severe) at 5.5 years did not differ between preterm children exposed and not exposed to tocolytics (relative risk [RR], 1.11; 95% CI, 0.85-1.45; P = .44) or in preterm infants exposed to atosiban compared with those exposed to CCBs (RR, 0.94; 95% CI, 0.67-1.32; P = .71).Conclusions and relevanceIn this study, tocolytics were not associated with neurodevelopmental disabilities among very preterm children surviving at 5.5 years.

Project description:Intraventricular hemorrhage (IVH) in preterm neonates presents a high risk for developing posthemorrhagic ventricular dilatation (PHVD), a severe complication that can impact survival and long-term outcomes. Early detection of PHVD before clinical onset is crucial for optimizing therapeutic interventions and providing accurate parental counseling. This study explores the potential of explainable machine learning models based on targeted liquid biopsy proteomics data to predict outcomes in preterm neonates with IVH. In recent years, research has focused on leveraging advanced proteomic technologies and machine learning to improve prediction of neonatal complications, particularly in relation to neurological outcomes. Machine learning (ML) approaches, combined with proteomics, offer a powerful tool to identify biomarkers and predict patient-specific risks. However, challenges remain in integrating large-scale, multiomic datasets and translating these findings into actionable clinical tools. Identifying reliable, disease-specific biomarkers and developing explainable ML models that clinicians can trust and understand are key barriers to widespread clinical adoption. In this prospective longitudinal cohort study, we analyzed 1109 liquid biopsy samples from 99 preterm neonates with IVH, collected at up to six timepoints over 13 years. Various explainable ML techniques-including statistical, regularization, deep learning, decision trees, and Bayesian methods-were employed to predict PHVD development and survival and to discover disease-specific protein biomarkers. Targeted proteomic analyses were conducted using serum and urine samples through a proximity extension assay capable of detecting low-concentration proteins in complex biofluids. The study identified 41 significant independent protein markers in the 1600 calculated ML models that surpassed our rigorous threshold (AUC-ROC of ≥0.7, sensitivity ≥ 0.6, and selectivity ≥ 0.6), alongside gestational age at birth, as predictive of PHVD development and survival. Both known biomarkers, such as neurofilament light chain (NEFL), and novel biomarkers were revealed. These findings underscore the potential of targeted proteomics combined with ML to enhance clinical decision-making and parental counseling, though further validation is required before clinical implementation.
