RESUMO
OBJECTIVE: To demonstrate and validate the improvement of current risk stratification for bronchopulmonary dysplasia (BPD) early after birth by plasma protein markers (sialic acid-binding Ig-like lectin 14 (SIGLEC-14), basal cell adhesion molecule (BCAM), angiopoietin-like 3 protein (ANGPTL-3)) in extremely premature infants. METHODS AND RESULTS: Proteome screening in first-week-of-life plasma samples of n = 52 preterm infants <32 weeks gestational age (GA) on two proteomic platforms (SomaLogic®, Olink-Proteomics®) confirmed three biomarkers with significant predictive power: BCAM, SIGLEC-14, and ANGPTL-3. We demonstrate high sensitivity (0.92) and specificity (0.86) under consideration of GA, show the proteins' critical contribution to the predictive power of known clinical risk factors, e.g., birth weight and GA, and predicted the duration of mechanical ventilation, oxygen supplementation, as well as neonatal intensive care stay. We confirmed significant predictive power for BPD cases when switching to a clinically applicable method (enzyme-linked immunosorbent assay) in an independent sample set (n = 25, p < 0.001) and demonstrated disease specificity in different cohorts of neonatal and adult lung disease. CONCLUSION: While successfully addressing typical challenges of clinical biomarker studies, we demonstrated the potential of BCAM, SIGLEC-14, and ANGPTL-3 to inform future clinical decision making in the preterm infant at risk for BPD. TRIAL REGISTRATION: Deutsches Register Klinische Studien (DRKS) No. 00004600; https://www.drks.de . IMPACT: The urgent need for biomarkers that enable early decision making and personalized monitoring strategies in preterm infants with BPD is challenged by targeted marker analyses, cohort size, and disease heterogeneity. We demonstrate the potential of the plasma proteins BCAM, SIGLEC-14, and ANGPTL-3 to identify infants with BPD early after birth while improving the predictive power of clinical variables, confirming the robustness toward proteome assays and proving disease specificity. Our comprehensive analysis enables a phase-III clinical trial that allows full implementation of the biomarkers into clinical routine to enable early risk stratification in preterms with BPD.

OBJECTIVE: To evaluate the incidence of termination of pregnancies (TOP) and factors associated with the decision for TOP in prenatally detected congenital diaphragmatic hernia (CDH). STUDY DESIGN: Single-centre retrospective cohort includes all prenatally detected CDH cases born between January 2009 and December 2021. Parental factors, such as parity, and fetal characteristics, such as disease severity, were collected. Descriptive statistics were used to present the data. Differences between terminated and continued pregnancies were analysed. RESULTS: The study population consisted of 278 prenatally detected CDH cases of which 80% detected <24 weeks of gestation. The TOP rate was 28% in cases that were detected <24 weeks of gestation. Twenty continued pregnancies resulted in either intrauterine fetal demise (n = 6), preterm birth <24 weeks (n = 2), or comfort care after birth (n = 12). The survival rate was 70% in the remaining 195 live born cases. Factors associated with the decision for TOP were additional fetal genetic or anatomical abnormalities (p < 0.0001) and expected severity of pulmonary hypoplasia in left-sided CDH (p = 0.0456). CONCLUSION: The decision to terminate a pregnancy complicated by fetal CDH depends on the severity of pulmonary hypoplasia and the presence of additional abnormalities. This emphasises the importance of early referral to expertise centres for detailed evaluation and multidisciplinary counselling.

OBJECTIVE: To examine the association between prenatal stomach position (SP) grade and stomach volume (SV) and the need for pulmonary hypertension (PH) treatment after birth in prenatally diagnosed left-sided congenital diaphragmatic hernia (CDH), live born >34 weeks. METHODS: In retrospect, SP grade and SV were determined in fetuses with isolated left-sided CDH from 19 weeks gestational age (GA) onwards at three different time periods (≤24 weeks' GA: US1, 24-30 weeks' GA: US2; ≥30 weeks' GA: US3). Primary outcome was need for treatment of PH after birth. Secondary analyses included the predictive value of SP and SV for other respiratory outcomes and postnatal defect size. RESULTS: A total of 101 fetuses were included. SP grade was significantly associated with need for treatment of PH (US1, US2, and US3: p < 0.02). Also, prenatal SP grade was positively associated with defect size and development of chronic lung disease (CLD) in survivors. No association was found between SV and respiratory morbidities or postnatal defect size. CONCLUSION: SP grade in left-sided CDH fetuses is associated with an increased need for PH treatment, a larger postnatal defect size and CLD in survivors. We consider SP determination a valuable contribution to the prenatal assessment of left-sided CDH.

PURPOSE: We developed a pharmacokinetic model of intravenous sildenafil in newborns with congenital diaphragmatic hernia (CDH) to achieve a target plasma concentration of over 50 µg/l. METHODS: Twenty-three CDH newborns with pulmonary hypertension (64 blood samples) received intravenous sildenafil. Patients received a loading dose of 0.35 mg/kg (IQR 0.16 mg/kg) for 3 h, followed by a continuous infusion of 1.5 mg/kg/day (IQR 0.1 mg/kg/day). For model development, non-linear mixed modeling was used. Inter-individual variability (IIV) and inter-occasion variability were tested. Demographic and laboratory parameters were evaluated as covariates. Normalized prediction distribution errors (NPDE) and visual predictive check (VPC) were used for model validation. RESULTS: A two-compartment disposition model of sildenafil and a one-compartment disposition model of desmethyl sildenafil (DMS) was observed with IIV in sildenafil and DMS clearance and volume of distribution of sildenafil. NPDE and VPC revealed adequate predictability. Only postnatal age increased sildenafil clearance. This was partly compensated by a higher DMS concentration, which also has a therapeutic effect. In this small group of patients, sildenafil was tolerated well. CONCLUSIONS: This model for sildenafil in CDH patients shows that concentration-targeted sildenafil dosing of 0.4 mg/kg in 3 h, followed by 1.6 mg/kg/day continuous infusion achieves appropriate sildenafil plasma levels.

OBJECTIVES: The aim of this study was to assess the effect of intravenous (IV) insulin administration in children with severe acute asthma (SAA) and hyperglycemia on IV salbutamol consumption and length of stay (LOS) in a pediatric intensive care unit (PICU). METHODS: Retrospective, descriptive study of the clinical course before and after implementation of an insulin protocol for the treatment of hyperglycemia (i.e. blood glucose >8 mmol/L or 144 mg/dL, respectively) in the PICU of a tertiary care university hospital. Admissions between 1994 and 2010 were reviewed. The insulin protocol was introduced in 2006. RESULTS: A total of 131 pediatric patients with SAA complicated by hyperglycemia requiring IV salbutamol were included. Severity of illness before and after implementation of the insulin protocol did not significantly differ. The insulin-treated patient group had significantly higher maximum blood glucose levels and higher cumulative IV salbutamol dose than the non-treated group. There were no differences between these groups in the duration of IV salbutamol administration and LOS. CONCLUSIONS: In view of the lack of difference in outcomes and considering that the insulin protocol is labor-intensive, the question is whether this protocol is efficacious for the treatment of pediatric SAA associated with hyperglycemia.

OBJECTIVE: The aim of the study was to evaluate the oxygen saturation index (OSI) as an early predictor of clinical deterioration in infants with congenital diaphragmatic hernia (CDH). METHODS: A single-center retrospective cohort study was conducted in consecutive infants with isolated CDH with continuous OSI measurements collected in the first 24 h after birth between June 2017 and July 2021. Outcomes of interest were pulmonary hypertension, extracorporeal membrane oxygenation (ECMO)-therapy, and mortality. We evaluated the discriminative values of the maximum OSI value and of mean OSI values with receiver operator characteristic (ROC) analysis and the area under the ROC curve. RESULTS: In 42 infants with 49,473 OSI measurements, the median OSI was 5.0 (interquartile range 3.1-10.6). Twenty-seven infants developed pulmonary hypertension on a median of day 1 (1-1), of which 15 infants had an indication for ECMO-therapy, and 6 infants died. Maximum OSI values were associated with pulmonary hypertension, ECMO-therapy, and mortality. Mean OSI values had an acceptable discriminative ability for pulmonary hypertension and an excellent discriminative ability for ECMO-therapy and mortality. Although OSI measurements were not always present in the first hours after birth, we determined discriminative cut-offs for mean OSI values already in these first hours for pulmonary hypertension, the need for ECMO-therapy, and mortality. CONCLUSIONS: Continuous OSI evaluation is a promising modality to identify those infants at highest risk for clinical deterioration already in the first hours after birth. This provides an opportunity to tailor postnatal management based on the individual patient's needs.

OBJECTIVES: Studies concerning cardiopulmonary outcomes of adults born with congenital diaphragmatic hernia (CDH) are sparse. Moreover, they don't include participants who have been treated with extracorporeal membrane oxygenation (ECMO) during the neonatal period. This study evaluated the cardiopulmonary morbidities in young adults born with CDH. METHODS: We assessed 68 participants between the ages of 18 and 30 years. The assessment included auxology assessment, lung function tests, pulmonary imaging, cardiopulmonary exercise testing, and echocardiography. RESULTS: Lung function parameters in the overall group were significantly worse than normal values. Mean (SD) scores postbronchodilator forced expiratory volume in 1 second were -2.91 (1.38) in the ECMO-treated and -1.20 (1.53) in the non-ECMO-treated participants. Chest computed tomography scans showed mild to moderate abnormal lung structure in all ECMO-treated participants, and to a lesser extent in non-ECMO treated participants. A recurrent diaphragmatic defect was observed in 77% of the ECMO-treated group and in 43% of the non-ECMO-treated group. Except for 2 cases with acute symptoms, no clinical problems were noted in cases of recurrence. Cardiopulmonary exercise testing revealed mean (SD) percentage predicted peak oxygen consumption per kilogram of 73 (14)% and 88 (16)% in ECMO-treated and non-ECMO-treated participants, respectively. The mean (SD) workload was normal in the non-ECMO-treated group (111 [25]% predicted); in the ECMO-treated group, it was 89 (23)%. Cardiac evaluation at rest revealed no signs of pulmonary hypertension. CONCLUSIONS: In young adults who survived treatment of CDH, significant pulmonary morbidity, reduced exercise capacity, and frequent hernia recurrence should be anticipated. Lifelong follow-up care, with the emphasis on prevention of further decline, is to be recommended.
RESUMO
OBJECTIVES: To longitudinally evaluate self-reported health status (HS) and quality of life (QoL) in 8- and 12-year-old survivors of congenital diaphragmatic hernia (CDH). We hypothesized that HS would improve with age-as associated health problems tend to decline-whereas QoL would decrease, as the children start to compare themselves with peers. METHODS: Self-reported HS and QoL of 133 children born between 1999 and 2013 who had joined our standardized follow-up program were routinely assessed at the ages of 8 and 12 with generic, internationally validated, standardized instruments. Longitudinal evaluation of total and subscale scores was performed using general linear model analyses. In addition, we compared these scores to sex- and age-specific normative data. RESULTS: Between ages 8 and 12, boys born with CDH perceived a decline in HS (mean difference -7.15, P < .001). Self-reported QoL did not change over time in both boys and girls. At both ages, HS was significantly lower than that of healthy peers (effect size = 0.71, P = .001 for boys, and effect size = 0.69, P = .003 for girls), whereas differences in QoL were small. CONCLUSIONS: Children born with CDH are at risk for declining HS between 8 and 12 years, but not QoL, compared with healthy peers. Given that children born with CDH tend to grow into deficits, our findings highlight the need for continued somatic and psychological assessments in adolescent and adult CDH survivors.

INTRODUCTION: The oxygenation index (OI) is a marker for respiratory disease severity and adverse neonatal outcomes. The oxygen saturation index (OSI) is an alternative that allows for continuous noninvasive monitoring, but evidence for clinical use in critically ill neonates is scarce. The aim of this study was to evaluate the OSI as compared to the OI in term neonates with a congenital diaphragmatic hernia (CDH). METHODS: A single-center retrospective cohort study was conducted including all live-born infants with an isolated CDH between June 2017 and December 2020. Paired values of the OI and OSI in the first 24 h after birth were collected. The relation between OI and OSI measurements was assessed, taking into account arterial pH, body temperature, and preductal versus postductal location of oxygen saturation measurement or arterial blood sampling. The predictive values for pulmonary hypertension, need for extracorporeal membrane oxygenation therapy, and survival at discharge were evaluated. RESULTS: Of 33 subjects included, 398 paired values of the OI (median 5.8 [3.3-17.2]) and OSI (median 7.3 [3.6-14.4]) were collected. The OI and OSI correlated strongly (r = 0.77, p < 0.001). The OSI values corresponding to the clinically relevant OI values (10, 15, 20, and 40) were 8.9, 10.9, 12.9, and 20.9, respectively. The predictive values of the OI and OSI were comparable for all adverse neonatal outcomes. No difference was found in the area under the receiver operating characteristic curves for the OI and the OSI for adverse neonatal outcomes. CONCLUSIONS: The OSI could replace the OI in clinical practice in infants with a CDH.

Background: Infants with a congenital diaphragmatic hernia (CDH) and expected mild pulmonary hypoplasia have an estimated survival rate of 90%. Current guidelines for delivery room management do not consider the individual patient's disease severity, but an individualized approach with spontaneous breathing instead of routine mechanical ventilation could be beneficial for the mildest cases. We developed a resuscitation algorithm for this individualized approach serving two purposes: improving the success rate by structuring the approach and providing a guideline for other centers. Methods: An initial algorithm was discussed with all local stakeholders. Afterwards, the resulting algorithm was refined using input from international experts. Results: Eligible CDH infants: left-sided defect, observed to expected lung-to-head ratio ≥50%, gestational age at birth ≥37.0 weeks, and no major associated structural or genetic abnormalities. To facilitate fetal-to-neonatal transition, we propose to start stabilization with non-invasive respiratory support and to adjust this individually. Conclusions: Infants with mild CDH might benefit from an individualized approach for neonatal resuscitation. Herein, we present an algorithm that could serve as guidance for centers implementing this.
RESUMO
INTRODUCTION: Pulmonary hypertension is a major determinant of postnatal survival in infants with a congenital diaphragmatic hernia (CDH). The current care during the perinatal stabilisation period in these infants might contribute to the development of pulmonary hypertension after birth-in particular umbilical cord clamping before lung aeration. An ovine model of diaphragmatic hernia demonstrated that cord clamping after lung aeration, called physiological-based cord clamping (PBCC), avoided the initial high pressures in the lung vasculature while maintaining adequate blood flow, thereby avoiding vascular remodelling and aggravation of pulmonary hypertension. We aim to investigate if the implementation of PBCC in the perinatal stabilisation period of infants born with a CDH could reduce the incidence of pulmonary hypertension in the first 24 hours after birth. METHODS AND ANALYSIS: We will perform a multicentre, randomised controlled trial in infants with an isolated left-sided CDH, born at ≥35.0 weeks. Before birth, infants will be randomised to either PBCC or immediate cord clamping, stratified by treatment centre and severity of pulmonary hypoplasia on antenatal ultrasound. PBCC will be performed using a purpose-built resuscitation trolley. Cord clamping will be performed when the infant is considered respiratory stable, defined as a heart rate >100 bpm, preductal oxygen saturation >85%, while using a fraction of inspired oxygen of <0.5. The primary outcome is pulmonary hypertension diagnosed in the first 24 hours after birth, based on clinical and echocardiographic parameters. Secondary outcomes include neonatal as well as maternal outcomes. ETHICS AND DISSEMINATION: Central ethical approval was obtained from the Medical Ethical Committee of the Erasmus MC, Rotterdam, The Netherlands (METC 2019-0414). Local ethical approval will be obtained by submitting the protocol to the regulatory bodies and local institutional review boards. TRIAL REGISTRATION NUMBER: NCT04373902.

Sildenafil is a selective phosphodiesterase type-5 inhibitor that is increasingly used to treat pulmonary hypertension (PH) in neonates. Only little is known about the relation between the dose of sildenafil, plasma concentrations, and the degree of toxicity. Here, we present a young infant with congenital diaphragmatic hernia and PH who received an unintentional 10-fold overdose of oral sildenafil for 6 consecutive days. This overdose, compared to the therapeutic dose, resulted in increased plasma concentrations of sildenafil from 42 to 521 mcg/L and desmethylsildenafil from 81 to 393 mcg/L. However, the high exposure only led to diarrhea, without any other serious adverse events. This case describes the mild symptoms upon an overdose with the role of therapeutic drug monitoring to monitor exposure in relation to symptoms and therewith support clinical decision-making.

Background and Objectives: Children born with congenital diaphragmatic hernia (CDH) and treated with extracorporeal membrane oxygenation (ECMO), are at risk for motor function impairment during childhood. We hypothesized that all children born with CDH are at risk for persistent motor function impairment, irrespective of ECMO-treatment. We longitudinally assessed these children's motor function. Methods: Children with CDH with and without ECMO-treatment, born 1999-2007, who joined our structural prospective follow-up program were assessed with the Movement Assessment Battery for Children (M-ABC) at 5, 8, 12 years. Z-scores were used in a general linear model for longitudinal analysis. Results: We included 55 children, of whom 25 had been treated with ECMO. Forty-three (78%) were evaluated at three ages. Estimated mean (95% CI) z-scores from the general linear model were -0.67 (-0.96 to -0.39) at 5 years of age, -0.35 (-0.65 to -0.05) at 8 years, and -0.46 (-0.76 to -0.17) at 12 years. The 5- and 8-years scores differed significantly (p = 0.02). Motor development was significantly below the norm in non-ECMO treated patients at five years; -0.44 (-0.83 to -0.05), and at all ages in the ECMO-treated-patients: -0.90 (-1.32 to -0.49), -0.45 (-0.90 to -0.02) and -0.75 (-1.2 to -0.34) at 5, 8, and 12 years, respectively. Length of hospital stay was negatively associated with estimated total z-score M-ABC (p = 0.004 multivariate analysis). Conclusion: School-age children born with CDH are at risk for motor function impairment, which persists in those who received ECMO-treatment. Especially for them long-term follow up is recommended.
RESUMO
INTRODUCTION: A congenital lung abnormality (CLA) is often found in conjunction with other abnormalities but screening guidelines for newborns with CLA have not yet been reported. We aimed to assess the incidence of associated anomalies in CLA patients born or followed up at our centre and the need for additional screening of newborns with a CLA. METHODS: From a retrospective chart review of all patients born with a CLA between January 1999 and January 2019, we identified patients diagnosed with a congenital pulmonary airway malformation, bronchopulmonary sequestration, congenital lobar overinflation, bronchogenic cyst, or lung agenesis. Associated anomalies were noted and categorized according to the affected organ system. RESULTS: Twenty-eight (14%) of 196 CLA patients had a major associated anomaly. This was most frequent in conjunction with a lung agenesis (100%) or bronchogenic cyst (29%). Congenital heart defects (32%) and gastrointestinal defects (18%) were the most frequently associated anomalies. Examination of newborns with a CLA should focus on the cardiovascular and gastrointestinal tract, and a chest and abdominal radiograph may be useful to assess signs of major associated anomalies, regardless of the clinical course.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a rare congenital anomaly with a mortality of â¼27%. The Congenital Diaphragmatic Hernia Study Group (CDHSG) developed a simple postnatal clinical prediction rule to predict mortality in newborns with CDH. Our aim for this study is to externally validate the CDHSG rule in the European population and to improve its prediction of mortality by adding prenatal variables. METHODS: We performed a European multicenter retrospective cohort study and included all newborns diagnosed with unilateral CDH who were born between 2008 and 2015. Newborns born from November 2011 onward were included for the external validation of the rule (n = 343). To improve the prediction rule, we included all patients born between 2008 and 2015 (n = 620) with prenatally diagnosed CDH and collected pre- and postnatal variables. We build a logistic regression model and performed bootstrap resampling and computed calibration plots. RESULTS: With our validation data set, the CDHSG rule had an area under the curve of 79.0%, revealing a fair predictive performance. For the new prediction rule, prenatal herniation of the liver was added, and absent 5-minute Apgar score was taken out. The new prediction rule revealed good calibration, and with an area under the curve of 84.6%, it had good discriminative abilities. CONCLUSIONS: In this study, we externally validated the CDHSG rule for the European population, which revealed fair predictive performance. The modified rule, with prenatal liver herniation as an additional variable, appears to further improve the model's ability to predict mortality in a population of patients with prenatally diagnosed CDH.

Congenital diaphragmatic hernia (CDH) is associated with high mortality rates and significant pulmonary morbidity, mainly due to disrupted lung development related to herniation of abdominal organs into the chest. Pulmonary hypertension is a major contributor to both mortality and morbidity, however, treatment modalities are limited. Novel prenatal and postnatal interventions, such as fetal surgery and medical treatments, are currently under investigation. Until now, the perinatal stabilisation period immediately after birth has been relatively overlooked, although optimising support in these early stages may be vital in improving outcomes. Moreover, physiological parameters obtained from the perinatal stabilisation period could serve as early predictors of adverse outcomes, thereby facilitating both prevention and early treatment of these conditions. In this review, we focus on the perinatal stabilisation period by discussing the current delivery room guidelines in infants born with CDH, the physiological changes occurring during the fetal-to-neonatal transition in CDH, novel delivery room strategies and early predictors of adverse outcomes. The combination of improvements in the perinatal stabilisation period and early prediction of adverse outcomes may mitigate the need for specific postnatal management strategies.

The number of children requiring pediatric intensive care unit (PICU) admission for severe acute asthma (SAA) around the world has increased. OBJECTIVES: We investigated whether this trend in SAA PICU admissions is present in the Netherlands. METHODS: A multicenter retrospective cohort study across all tertiary care PICUs in the Netherlands. Inclusion criteria were children (2-18 years) hospitalized for SAA between 2003 and 2013. Data included demographic data, asthma diagnosis, treatment, and mortality. RESULTS: In the 11-year study period 590 children (660 admissions) were admitted to a PICU with a threefold increase in the number of admissions per year over time. The severity of SAA seemed unchanged, based on the first blood gas, length of stay and mortality rate (0.6%). More children received highflow nasal cannula (P < 0.001) and fewer children needed invasive ventilation (P < 0.001). In 58% of the patients the maximal intravenous (IV) salbutamol infusion rate during PICU admission was 1 mcg/kg/min. However, the number of patients treated with IV salbutamol in the referring hospitals increased significantly over time (P = 0.005). The proportion of steroid-naïve patients increased from 35% to 54% (P = 0.004), with a significant increase in both age groups (2-4 years [P = 0.026] and 5-17 years [P = 0.036]). CONCLUSIONS: The number of children requiring PICU admission for SAA in the Netherlands has increased. We speculate that this threefold increase is explained by an increasing number of steroid-naïve children, in conjunction with a lowered threshold for PICU admission, possibly caused by earlier use of salbutamol IV in the referring hospitals.
