Filter by:Serial quantitative measurements of plasma pro-endothelin-1 concentrations in very preterm infants. Comparing pro-endothelin-1 with established clinical indices of bronchopulmonary dysplasia (BPD). Hypothesis: Pulmonary-vascular remodeling in infants developing BPD is directly related to circulating pro-endothelin-1, which therefore serves as surrogate marker of BPD.
This is an observational study that proposes to collect clinical, physiological, cellular and molecular information in an attempt to identify a set of factors that may predict the risk for persistent lung disease in babies born prematurely.
The study hypothesis states that giving early enteral Vitamin D supplementation to preterm infants will decrease respiratory morbidity in extremely preterm infants.
A lung condition called bronchopulmonary dysplasia (BPD) is a major cause of poor outcomes and death for premature infants. Infants with BPD are also at high risk for pulmonary hypertension (PH)-an important contributor to their condition. Previous research has suggested that a protein in the blood, endothelin-1 (ET-1), is associated with pulmonary disease. This study aims to investigate the incidence of PH and levels of ET-1 among premature babies with BPD. It will also potentially allow us to focus further research efforts and treatment towards these infants, some of our sickest patients at LPCH.
Inhaled nitric oxide in preterm babies with respiratory failure or ventilator dependence will: 1. decrease the incidence of Bronchopulmonary Dysplasia (BPD) or death 2. shorten the length of oxygen therapy and hospital stay ,reduce the cost of hospital stay without increasing adverse effect
Bronchopulmonary Dysplasia (BPD) is a multi-factorial disease process that is the end result of an immature, surfactant deficient lung that has been exposed to hyperoxia, mechanical ventilation and infection. These conditions initiate an inflammatory response characterized by elevated inflammatory cell infiltrates and proinflammatory cytokines that lead to the development of significant acute and chronic lung injury. The study drug, rhCC10, is a recombinant version of natural human CC10 protein. Native CC10 is produced primarily by non-ciliated respiratory epithelial cells, called Clara cells and is the most abundant protein in the mucosal fluids in normal healthy lungs. The purpose of this study was to evaluate the pharmacokinetics, safety, tolerability and anti-inflammatory effects of a single intratracheal (IT) dose of rhCC10 to intubated premature infants receiving positive pressure ventilation for treatment of respiratory distress syndrome (RDS) to prevent long term respiratory complications referred to as bronchopulmonary dysplasia, and, more recently, as chronic respiratory morbidity (CRM; asthma, cough, wheezing, multiple respiratory infections). CC10 regulates inflammatory responses and protects the structural integrity of pulmonary tissue while preserving pulmonary mechanical function during various insults (eg. viral infection, bacterial endotoxin, ozone, allergens, hyperoxia). Together these properties suggest that administration of rhCC10 may help to facilitate development of normal airway epithelia and prevent the inflammation that leads to CRM in these infants.
The goal of IMPROV is to identify molecular mechanisms that contribute to lung injury and long-term breathing problems in preterm infants by investigating two interrelated biochemical pathways: the urea cycle-nitric oxide pathway and the glutathione pathway. The investigators hypothesize that prematurity-related limitations in the function of these important biochemical pathways contribute to respiratory disease risk over the first year of life.
Very premature infants often cannot breathe on their own and require assistance with a respirator. Conventional respirators deliver air or oxygen via a breathing tube placed through the mouth to the airway (endotracheal tube). A prolonged use of an endotracheal tube is associated with injury to the lungs. Currently, a premature baby has to be ventilated through an endotracheal tube until he/she can fully breathe independently. In the current study, in order to shorten the time with an endotracheal tube, we utilized an alternative, less invasive ventilation procedure, nasal intermittent positive pressure ventilation (NIPPV). This procedure provides help with breathing, but requires only nasal, not endotracheal tubes. We hypothesized that NIPPV might help babies breathe, at an early stage in their recovery, when they could not breathe independently yet. Thus, by switching babies at this early stage from a regular respirator to NIPPV, we should be able to shorten the use of an injurious endotracheal tube.
Urinary ascorbyl peroxide level in the first week of life will be a good predictor of Bronchopulmonary dysplasia (BPD) in preterm infants less than 33 weeks of gestation.
EPIPAGEADO is an observational study. Respiratory symptoms and lung function will be evaluated in very low birth weight and term infants, born in 1997 and included in the French EPIPAGE cohort.
