Endothelial Progenitor and Mesenchymal Stromal Cells in Newborns With Congenital Diaphragmatic Hernia Undergoing Extracorporeal Membrane Oxygenation.

ABSTRACT: Background: Endothelial progenitor (EPC) and mesenchymal stromal cells (MSC) can regenerate damaged endothelium and thereby improve pulmonary endothelial dysfunction. We do not know, how extracorporeal membrane oxygenation (ECMO) might affect EPC- and MSC-mediated regenerative pathways in patients with congenital diaphragmatic hernia (CDH). Therefore, we investigated, if ECMO support impacts EPC and MSC numbers in CDH patients. Methods: Peripheral blood mononuclear cells from newborns with ECMO-dependent (n = 18) and ECMO-independent CDH (n = 12) and from healthy controls (n = 12) were isolated. The numbers of EPC and MSC were identified by flowcytometry. Serum levels of vascular endothelial growth factor (VEGF) and angiopoietin (Ang)-2 were determined. Results: EPC and MSC were elevated in newborns with CDH. ECMO-dependent infants had higher EPC subpopulation counts (2,1-7,6-fold) before treatment compared to ECMO-independent infants. In the disease course, EPC and MSC subpopulation counts in ECMO-dependent infants were lower than before ECMO initiation. During ECMO, VEGF serum levels were significantly reduced (by 90.5%) and Ang2 levels significantly increased (by 74.8%). Conclusions: Our data suggest that ECMO might be associated with a rather impaired mobilization of EPC and MSC and with a depression of VEGF serum levels in newborns with CDH.

Project description:ImportanceProstacyclin (PGI2) is a therapeutic option to treat congenital diaphragmatic hernia (CDH)-associated pulmonary hypertension in neonates. Its use may decrease the need for extracorporeal life support (ECLS).ObjectiveTo evaluate the association of early PGI2 therapy with ECLS use and outcomes among patients with CDH.Design, setting, and participantsThis was a cohort study from the CDH Study Group (CDHSG) registry of patients born from January 2007 to December 2019. Patients were from 88 different tertiary pediatric referral centers worldwide that contributed data to the CDHSG. Patients were included in the study if they were admitted within the first week of life. Propensity score matching was performed using estimated gestational age, birth weight, transfer status, 1-minute and 5-minute Apgar scores, highest and lowest partial pressure of arterial carbon dioxide in the first 24 hours of life, and degree of pulmonary hypertension as covariates to generate a matched cohort of exposed and unexposed patients. Data were analyzed from January 2021 to December 2022.ExposuresEarly PGI2 therapy was defined as initiation of PGI2 within the first week of life. Patients who received ECLS were included in the early PGI2 group if PGI2 was started prior to ECLS.Main outcomes and measuresThe primary outcome of the study was the proportion of patients receiving ECLS in the exposed and unexposed groups.ResultsOf 6227 patients who met inclusion criteria (mean [SD] gestational age, 37.4 [2.36] weeks; 2618 [42%] female), 206 (3.3%) received early PGI2 therapy. ECLS was used in 46 of 206 patients who received PGI2 (22.2%) and 1682 of 6021 who did not (27.9%). After propensity score matching, there were 147 patients in the treatment and control groups. Thirty-four patients who received PGI2 (23.3%) and 63 who did not (42.9%) received ECLS. Those who received PGI2 were less likely to receive ECLS (adjusted odds ratio, 0.39; 95% CI, 0.22-0.68) and had shorter mean (SD) duration of ECLS (8.6 [3.73] days vs 12.6 [6.61] days; P < .001), although there was no significant difference in in-hospital mortality.Conclusions and relevanceIn this study, there was decreased use of ECLS and decreased ECLS duration among patients with CDH who started PGI2 therapy during the first week of life. These results identify a potential advantage of early prostacyclin therapy in this population.
