View clinical trials related to BPD - Bronchopulmonary Dysplasia.
Filter by:Bronchopulmonary dysplasia (BPD) is a common, major complication of premature birth, associated with developmental and health consequences that continue into adulthood. Prediction of who will have these problems is challenging using traditional definitions of disease. It is believed that underdevelopment and injury occur in both lung tissue and the blood vessels in the lungs, with a sophisticated interplay between them that contributes to lung disease seen in prematurity. New magnetic resonance imaging (MRI) techniques can delineate tissue structure with unprecedented granularity, assessing lung tissue, blood vessels, and their interplay. The ability to identify, at an early stage, those infants destined for chronic lung disease with greater certainty will be useful in counseling families and critical for the effective introduction of promising new BPD therapies. 319 infants born less than 29 weeks gestation will be recruited from 4 centres, including 5 babies who received stem cell therapy in a clinical trial. Babies will be evaluated at 36 weeks post-conception with lung MRI, oscillometry (lung function), echocardiogram (heart ultrasound), and oscillometry. Lung health will be assessed every 3 months by phone questionnaire and chart review. At 18-21 months post-conception, babies will undergo neurodevelopmental assessment and lung function testing. The investigators will look at how well baseline MRI markers predict subsequent lung health and development, independently and combined with echocardiogram, lung ultrasound, and traditional markers of BPD. The investigators anticipate that these new MRI markers will measure lung health safely and longitudinally in babies born extremely preterm. By identifying predictors of longer-term lung disease, clinicians will be able to allocate resources to babies at the highest risk of severe disease. Further, The investigators envision that MRI will help identify babies who would benefit most from interventions like stem cell therapy and be useful for evaluation of future treatments.
The research endeavors to examine the critical composition of Polyunsaturated Fatty Acids (PUFAs) in premature infants across different gestational stages and under varying disease conditions, and delineate the metabolic attributes of PUFAs in premature infants and their interplay with the onset of diseases. This study anticipates furnishing a theoretical foundation for the rationalization of PUFAs supplementation in premature infants and for informing strategies related to disease prevention and management.
The purpose of this study is to evaluate the safety and explore the PK/PD of L-CIT supplementation in preterm infants to prevent the development of inflammatory pathways initiated by low levels of plasma CIT, specifically in preterm infants with post surgical NEC and BPD±PH.
Assess the impact of steroid, diuretic, and fluid practices on BPD outcomes in extreme premature infants in the Banner - University Medical Center Phoenix (BUMCP) neonatal intensive care unit (NICU).
To study the effect of Autologous cord blood cells infusion on prevention of bronchopulmonary dysplasia in very preterm neonates
Premature infants have high rates of bronchopulmonary dysplasia (BPD) due to prematurity of the participants' lungs and the need for prolonged respiratory support. These infants are at increased risk for gastroesophageal reflux and aspiration which may exacerbate lung injury. Transpyloric feeds, specifically duodenal feeds, may be used to bypass the stomach and directly feed the duodenum decreasing the amount of gastric reflux contributing to aspiration. Duodenal feeds are equivalent to gastric feeds with regards to nutritional outcomes, and have been shown to decrease events of apnea and bradycardia in premature infants. This study will evaluate the feasibility and safety of duodenal feeds in premature infants. The hypothesis is that duodenal feeds may be safely and successfully performed in premature very low birth weight infants.
Despite significant improvement in preterm infant survival, the incidence of bronchopulmonary dysplasia (BPD) in infants born < 28 weeks gestational age (GA) has been relatively stable at ~40%, with 10,000-15,000 new cases estimated annually. Delivery room (DR) management of preterm infants during the initial resuscitation has a significant impact on future development of BPD. Current DR practice as recommended by the Neonatal Resuscitation Program (NRP), focuses on providing positive pressure ventilation (PPV) for intubated infants based on pressure limited ventilation (PLV). But with rapidly changing pulmonary compliance during the early newborn period, PLV may lead to under or over inflation of the lungs and induce significant volutrauma, barotrauma and/or atelectotrauma, all of which are associated in the pathogenesis of BPD. No studies have specifically reported tidal volume (TV) provided in the DR in intubated infants with current PLV practices. Similarly, no study has evaluated the safety and efficacy of volume targeted ventilation (VTV) in the DR and its impact on BPD. With the proposed study, in Phase I, the investigators aim to demonstrate that measuring TV in intubated infants receiving PPV via PLV is feasible. The investigators also seek to demonstrate that with PLV, TV is highly variable in the first few hours of life, even with the same peak inspiratory pressures (PiP) due to rapidly changing pulmonary compliance. A successful Phase I will demonstrate that measuring TV is feasible in the DR, and with information on real time actual TV achieved during PPV, it is possible to target the TV for a goal TV by adjusting the PiP provided. Phase II will be a pilot randomized control trial to demonstrate feasibility of VTV compared to PLV. The investigators will also aim to understand the pulmonary mechanics and physiology during VTV. A successful Phase II will demonstrate VTV is feasible, is associated with stable TV, decreased peak inspiratory pressure and oxygen needs compared to PLV, and not associated with increased complications compared to PLV. It will thereby justify a larger randomized control trial with enough power to evaluate the efficacy of VTV in reducing BPD and other long term pulmonary morbidities for preterm infants.
BACKGROUND: Human milk (HM) is recommended for all very low birth infants (VLBW)). Breast-milk is highly variable in nutrient content, failing to meet the nutritional demands of VLBW. Fortification of HM is recommended to prevent extra-uterine growth retardation and associated poor neurodevelopmental outcome. However, standard fortification with fixed dose multicomponent fortifier does not account for the variability in milk composition. Targeted fortification is a promising alternative and needs further investigation. The aim of the study is to evaluate if targeted fortification of human milk may optimize growth and development in preterm infants. STUDY DESIGN: Randomized single blind controlled trial. METHODS & ANALYSIS: We will recruit preterm infants (≤ 32 weeks of gestation) within the first 7 days of life. After reaching 80 ml/kg/day of enteral feeding, patients will be randomised to receive standard fortification (HMF, Nutricia) or targeted fortification (modular components: Bebilon Bialko, Nutricia - protein, Fantomalt, Nutricia - carbohydrates, Calogen, Nutricia - lipids). The intervention will continue until 37 weeks of post-conception age, or hospital discharge. Parents and outcome assessors will be blinded to the intervention. The primary outcome - weight gain velocity will be measured starting from the day infants regain their birth weight up to 4 weeks, then weekly until discharge. Secondary outcomes such as neurodevelopment at 12 months of corrected age (CA) will be assessed with Bayley Scale of Development III, repeated at 36 months of CA. Additionally a Wescheler Preschool and Primary Scale of Intelligence IV test will be applied at 3,5 years of CA. Secondary outcomes such as length and head growth, body composition will be assesed at discharge and at 4 months. Incidence of necrotizing enterocolitis (NEC), sepsis, retinopathy of prematurity (ROP) and bronchopulmonary dysplasia (BPD) will also be followed.
Infants delivered weighing less than 1 kg at birth (ELBW) are at high risk for the development of bronchopulmonary dysplasia (BPD) and Ventilator-Induced Lung Injury (VILI), in part because of the need for mechanical ventilation utilizing an endotracheal tube (MVET). In spite of strategies to minimize the need for MVET, the incidence of BPD in ELBW infants continues to be 20-80%. The hypothesis is that synchronized NIPPV will decrease the need for MVET and reduce BPD in ELBW infants as compared to NIPPV.
Extubation failure is a significant problem in preterm neonates and prolonged intubation is a well-documented risk factor for development of chronic lung disease. Out of the respiratory modalities available to extubate a preterm neonate; high flow nasal canula, nasal continuous positive airway pressure (nCPAP) and noninvasive positive pressure ventilation (NIPPV) are the most commonly used. A recent Cochrane meta-analysis concluded that NIPPV has lower extubation failure as compared to nCPAP (30% vs. 40%) NAVA (neurally adjusted ventilatory assist), a relatively new mode of mechanical ventilation in which the diaphragmatic electrical activity initiates a ventilator breath and adjustment of a preset gain (NAVA level) determines the peak inspiratory pressure. It has been reported to improve patient - ventilator synchrony and minimize mean airway pressure and ability to wean an infant from a ventilator. However till date there has been no head to head comparison of extubation failure in infants managed on NAVA with conventional ventilator strategies. In this study the investigators aim to compare primary extubation failure rates in infants/participants managed by NIPPV vs. NI-NAVA (non invasive NAVA). Eligible infants/participants will be randomized to be extubated to predefined NIPPV or NI-NAVA ventilator settings and will be assessed for primary extubation failure (defined as reintubation within 5 days after an elective extubation).
