Overview
The purpose of this study is to investigate the use of autologous umbilical cord blood (UCB) mononuclear cells to mitigate hypoxic neurologic injury among infants with high-risk congenital diaphragmatic hernia (CDH).
Eligibility
Inclusion Criteria:
- Diagnosis of CDH between 20 and 36 weeks estimated gestational age (EGA)
- Only one of the following fetal criteria and one of the following postnatal criteria must be met for enrollment. Fetal criteria: an ultrasound (US)-obtained observed to expected lung to head ratio (o/e LHR) less than or equal to 35% or 2) a fetal magnetic resonance imaging (fMRI)- obtained observed to expected total fetal lung volume (o/e TFLV) less than or equal to 35%. Postnatal criteria: 1) Cord blood gas (CBG) with potenital hydrogen (pH) <7.0, 2) Arterial blood gas (ABG) with pH <7.2 on 2 gasses within the first 24 hours, 3) Preductal oxygen saturation (O2 sat) <90% x 2 total hours (not necessarily consecutive) within the first 24 hours, or 4) Oxygenation Index (OI) >20 x 2 total hours (not necessarily consecutive) within the first 24 hours.
Exclusion Criteria:
- Genetic/chromosomal abnormality: Trisomy 21, Trisomy 18, Trisomy 13 or other, significant genetic abnormality. Microdeletions or other mild genetic abnormalities are not considered exclusionary.
- Severe/major cardiac anomaly: coarctation of the aorta, combined atrial and ventricular septal defects, hypoplastic left heart syndrome, tetralogy of fallot, double outlet right ventricle, atrioventricular canal defects, or other hemodynamically significant defects.
- Moderate/severe neurologic / intracranial abnormality: Grade III or IV intraparenchymal hemorrhage, space occupying mass or lesion, or clinically significant traumatic lesion such as a subdural or epidural hemorrhage.
- Prematurity <30 weeks estimated gestational age (EGA): Birth at 29 6/7 weeks or before
- Participation in an alternative prenatal intervention study: Fetoscopic Endotracheal Occlusion (FETO)
- Unwillingness / inability to return for follow-up evaluation and assessment
