Enteral Zinc to Improve Growth in Infants at Risk for Bronchopulmonary Dysplasia
Infant,PrematureBronchopulmonary Dysplasia1 moreMultiple factors contribute to growth failure in infants with BPD, including poor nutrient stores, inadequate intake, increased losses, and increased needs. Furthermore, compared to infants without BPD, those with BPD have increased resting metabolic rates and energy expenditure. Growth deficits manifest as lower weight, length, and head circumference, as well as changes in body composition. These deficits precede the development of BPD and persist post-discharge. While similar rates of growth are observed in very low birth weight infants with and without BPD once receiving equal calories, catch up growth does not occur in the BPD group. Thus, early growth deficits remained uncompensated. After iron, zinc is the most metabolically active trace element in the human body. It has a critical role in growth, through its actions on growth hormone, IGF-1, IGFBP-3, and bone metabolism. Prematurity is a risk factor for zinc deficiency, as 60% of zinc accretion occurs in the third trimester. Impaired intake and absorption or excess excretion can further increase this risk. Finally, periods of rapid growth, as seen in preterm infants, increase the need for zinc. Biochemically, zinc deficiency is defined by a serum zinc level less than 55mcg/dl. However, while zinc depletion is associated with deficiency, the opposite may not be true. For example, in starving patients, clinical symptoms of zinc deficiency occur during re-feeding, suggesting overall requirements are related to needs, regardless of overall zinc status. This may be the case in preterm infants, who may have a subclinical deficiency despite serum zinc level. Thus, zinc deficiency should be considered in infants with poor growth despite receiving adequate protein and calories. The objective of this study is to determine whether enteral zinc supplementation leads to improved growth in infants at risk for bronchopulmonary dysplasia (BPD). The investigator's hypothesis is that enteral zinc supplementation in very preterm infants at high risk for BPD will significantly improve growth compared to standard of care.
Clinic Features and Outcome of BPD (SGBPD)
Bronchopulmonary DysplasiaThis study described the perinatal high-risk factors and clinical manifestations of the children, and compared the high-risk factors, clinical manifestations and prognosis of BPD among different clinical subtypes by comparison between groups. BPD grading was performed using the 2018 grading standard to compare the distribution of I/II/III BPD among different groups.
Fast Assessment of Surfactant Deficiency in Preterm Infants to Speed up Treatment
Surfactant Deficiency Syndrome NeonatalRespiratory Distress Syndrome2 moreRecently the investigators have developed a point of care test (LS-test) to measure surfactant as lecithin in gastric aspirates from preterm infants. This test can be done immediately at delivery and potentially be used to guide surfactant treatment. To obtain evidence-based knowledge on harms and benefit of surfactant therapy guided by the L/S test, a randomized clinical trial with relevant clinical short-and long-term outcomes needs to be performed, which is why the FAST 2 Trial has been designed.
Early Versus Late Caffeine for ELBW Newborns
Bronchopulmonary DysplasiaApnea of PrematurityCaffeine is routinely used in the management of apnea of prematurity. Extremely low birth weight (ELBW) infants are at higher risk of mortality and various neonatal morbidities such as bronchopulmonary dysplasia (BPD) for which caffeine has been shown to be beneficial in very low birth weight (VLBW) infants. The investigators' previous unpublished retrospective studies and recently published retrospective studies demonstrated that early caffeine given within 48 hours of age tended to decrease the incidence of death and BPD in ELBW newborns. Retrospective design can be biased as newborns with mild lung disease may have received caffeine early for extubation. There are several studies on pharmacodynamics and pharmacokinetics of caffeine. The data regarding cumulative dosage of caffeine, caffeine levels and BPD outcome is deficient. Primary objective of this study is to test the hypothesis that early caffeine given within 24 hours of life will decrease incidence of mortality and BPD in ventilated ELBW newborns. This study will also test an additional hypothesis that higher caffeine dosage and caffeine levels are associated with decreased mortality and postnatal morbidities in studied newborns.
Antibiotic "Dysbiosis" in Preterm Infants
EnterocolitisNecrotizing6 moreProlonged antibiotic use in preterm neonates has significant consequences on the developing intestinal microbiome, metabolome and host response, predisposing the neonate to various major morbidities, including necrotizing enterocolitis (NEC), late-onset sepsis, bronchopulmonary dysplasia (BPD), and mortality. The hypothesis is that early and prolonged antibiotic use in preterm neonates has significant consequences on the developing intestinal microbiome, metabolome and host response, predisposing the neonate to various major morbidities. It is possible that the effect of this widespread antibiotic use outweighs the potential benefits. This study will randomize preterm infants born at less than 33 weeks gestation to either pre-emptive antibiotics or no-pre-emptive antibiotics. The purpose of this research is to evaluate the risks and benefits of current practice to determine optimal levels of antibiotic use that protects the babies from infection with minimal effect on the microbiome and subsequent adverse outcomes related to overuse of antibiotics.
No Treatment Versus Oral Ibuprofen Treatment for Patent Ductus Arteriosus in Preterm Infants
Bronchopulmonary Dysplasia (BPD)The purpose of this study is to evaluate the efficacy and safety of no treatment compared with ibuprofen treatment for patent ductus arteriosus in preterm infants. The study hypothesis is that no treatment is not inferior to oral ibuprofen treatment in preterm infants. (non-inferiority study)
Exogenous Surfactant in Very Preterm Neonates in Prevention of Bronchopulmonary Dysplasia
InfantPremature4 moreAdvances in perinatal care have made it possible to improve the survival of the most immature neonates, but at the cost of an increase in the population at risk of developing bronchopulmonary dysplasia (BPD). Measures that have attempted to limit the development of BPD are not always effective, or related to major side effects. The physiopathological factors that are identified in BPD should, in theory, respond to surfactant. Therefore, the use of an exogenous surfactant in neonates presenting with pulmonary disease requiring mechanical ventilation, leading to a significant risk of BPD, should allow earlier extubation and thus promote pulmonary healing and growth.
NCPAP + Heliox as a Treatment for Infant Respiratory Distress Syndrome (RDS)
Respiratory Distress SyndromeBronchopulmonary DysplasiaInfants born between 28 and 32 weeks' gestation with radiological findings and clinical symptoms of moderate RDS, requiring respiratory support with Nasal Continuous Positive Airway Pressure (NCPAP) within the first hour of life, were randomized to receive either standard medical air or a Heliox/Oxygen mixture 80/20 (Heliox) during the first 12 hours of life, followed by medical air until NCPAP was needed. The aim of the study was to assess the therapeutic effects of breathing a low-density gas mixture (heliox: 80% helium and 20% oxygen) in premature babies with Respiratory Distress Syndrome (RDS), undergoing NCPAP in terms of reducing the rate of mechanical ventilation (MV).
