Early inhaled glucocorticoid therapy to prevent bronchopulmonary dysplasia. (1/452)

BACKGROUND: The safety and efficacy of inhaled glucocorticoid therapy for asthma stimulated its use in infants to prevent bronchopulmonary dysplasia. We tested the hypothesis that early therapy with inhaled glucocorticoids would decrease the frequency of bronchopulmonary dysplasia in premature infants. METHODS: We conducted a randomized, multicenter trial of inhaled beclomethasone or placebo in 253 infants, 3 to 14 days old, born before 33 weeks of gestation and weighing 1250 g or less at birth, who required ventilation therapy. Beclomethasone was delivered in a decreasing dosage, from 40 to 5 microg per kilogram of body weight per day, for four weeks. The primary outcome measure was bronchopulmonary dysplasia at 28 days of age. Secondary outcomes included bronchopulmonary dysplasia at 36 weeks of postmenstrual age, the need for systemic glucocorticoid therapy, the need for bronchodilator therapy, the duration of respiratory support, and death. RESULTS: One hundred twenty-three infants received beclomethasone, and 130 received placebo. The frequency of bronchopulmonary dysplasia was similar in the two groups: 43 percent in the beclomethasone group and 45 percent in the placebo group at 28 days of age, and 18 percent in the beclomethasone group and 20 percent in the placebo group at 36 weeks of postmenstrual age. At 28 days of age, fewer infants in the beclomethasone group than in the placebo group were receiving systemic glucocorticoid therapy (relative risk, 0.6; 95 percent confidence interval, 0.4 to 1.0) and mechanical ventilation (relative risk, 0.8; 95 percent confidence interval, 0.6 to 1.0). CONCLUSIONS: Early beclomethasone therapy did not prevent bronchopulmonary dysplasia but was associated with lower rates of use of systemic glucocorticoid therapy and mechanical ventilation.  (+info)

Effect of early ambroxol treatment on lung functions in mechanically ventilated preterm newborns who subsequently developed a bronchopulmonary dysplasia (BPD). (2/452)

In a randomized trial in 102 preterm newborns with respiratory distress syndrome (RDS) it has been shown that early Ambroxol treatment (30 mg kg(-1) over the first 5 days) significantly reduces the incidence of RDS-associated complications [bronchopulmonary dysplasia (BPD), intraventricular haemorrhage, post-natal acquired pneumonia]. The aim of the present analysis was to investigate the effect of Ambroxol treatment on lung function in newborns who developed BPD. Respiratory function testing (RFT) was performed immediately after extubation and at day 28. Tidal volume (VT) and respiratory frequency (f) were measured during tidal breathing using the deadspace free flow-through technique. The lung mechanic parameter VT/maxPes was determined by measuring the maximal oesophageal pressure changes, maxPes, with a catheter tip pressure transducer. In the placebo group 36/50 infants were extubated within the first 28 days of life and 13/36 (36%) developed BPD. In the Ambroxol group 44/52 were extubated and 9/44 (20%) developed BPD. After extubation, RFT showed (i) no statistically significant difference in the ventilatory parameters of either treatment group, (ii) improved (P<0.05) lung mechanics (VT/maxPes) in Ambroxol group compared to controls (94+/-27 ml kPa(-1) vs. 8.1+/-2.6 ml kPa(-1)) and (iii) no statistically significant difference in lung function between infants with and without BPD. At day 28 we found (i) no effect of early Ambroxol treatment on lung functions, (ii) significantly (P < 0.05) higher f (58.5+/-11.7 min(-1) vs. 49.7+/-10.1 min(-1)) and significantly (P<0.01) lower V(T) (9.6+/-1.9 ml vs. 12.3+/-2.7 ml) and V(T)/maxPes (8.9+/-2.6 ml kPa(-1)] vs. 12.0+/-2.9 ml kPa(-1)) in infants with BPD compared to infants without and (iii) these differences are not influenced by early Ambroxol treatment. If the process of BPD development is induced, early Ambroxol treatment has no influence on impaired lung function at day 28.  (+info)

Use of corticosteroids and the outcome of infants with bronchopulmonary dysplasia. (3/452)

Ventilator-dependent premature infants are often treated with dexamethasone. Several trials showed that steroids while improve pulmonary compliance and facilitate extubation, some treated infants may have adverse effects, such as alterations of growth curves. We conducted this retrospective study to evaluate the effects of steroids on mechanical ventilation, oxygen therapy, hospital length stay and mortality, in ventilator-dependent infants with bronchopulmonary dysplasia (BPD) (defined as the need of oxygen supplementation at 28 days of life). Twenty-six newborns with BPD were evaluated during 9 - 42 days postpartum (mean = 31 days) and were divided into two groups: Group I - 14 newborns that did not receive dexamethasone, and Group II - 12 newborns that received dexamethasone at 14 - 21 days of life. Dexamethasone was given at a dose of 0.25 mg per kilogram of body weight twice daily intravenously for 3 days, after which the dose was tapered. RESULTS: There were no statistically significant differences in the mean length of mechanical ventilation (Group I - 37 days, Group II - 35 days); oxygen supplementation (Group I - 16 days, Group II - 29 days); hospital stay (Group I - 72 days, Group II - 113 days); mortality (Group I - 35.7%, Group II - 41.6%). At birth, Group II was lighter (BW: Group I - 1154 grams +/- 302, Group II - 791 grams +/- 165; p < 0.05) and smaller (height: Group I - 37.22 cm +/- 3.3, Group II - 33.5 +/- 2.4; p< 0.05) than Group I. At 40 weeks, there were no statistically significant differences between groups in relation to anthropometric measurements. CONCLUSIONS: The use of corticosteroids in bronchopulmonary dysplasic infants may influence the somatic growth during its use. However, after its suspension, a recovery seems to occur, suggesting that its influence could be transitory.  (+info)

Cytokine response during hyperoxia: sequential production of pulmonary tumor necrosis factor and interleukin-6 in neonatal rats. (4/452)

BACKGROUND: Exposure of newborn animals to high concentrations of oxygen leads to diffuse alveolar damage similar to that seen in bronchopulmonary dysplasia in human infants. Therefore, neonatal rats are a suitable practical model of hyperoxic lung damage in human infants. OBJECTIVE: To determine the involvement of tumor necrosis factor-alpha and interleukin-6 in lung injury in neonatal rats exposed to 100% O2 concentration. METHODS: A randomized controlled study was designed in which litters of term Sprague-Dawley rat pups were assigned to experimental or control groups. The pups in the experimental group were placed in 100% O2 from birth for 9 days, while the control pups were placed in room air. Twelve to 15 pups from each group were sacrificed on day 1, 3, 6, 9 and 13 after birth for bronchoalveolar lavage collection and lung histologic study. The bronchoalveolar lavage fluid was assayed for TNF alpha and IL-6. RESULTS: Newborn rats exposed to 100% O2 for the first 9 days of life showed severe pulmonary edema and hypercellularity on days 1 and 3, which then improved to nearly complete resolution on days 6 and 9. Pulmonary TNF alpha was produced early on O2 exposure (day 3) and pulmonary IL-6 later (days 6 and 9). CONCLUSIONS: Hyperoxia induces sequential production of pulmonary TNF alpha and IL-6, which corresponds to the severity of the pathological findings and the known inflammatory and anti-inflammatory role of these cytokines.  (+info)

Birth weight <1501 g and respiratory health at age 14. (5/452)

AIMS: To determine the respiratory health in adolescence of children of birth weight <1501 g, and to compare the results with normal birthweight controls. METHODS: Prospective cohort study of children born in the Royal Women's Hospital, Melbourne. Two cohorts of preterm children (86 consecutive survivors 500-999 g birth weight, and 124 consecutive survivors 1000-1500 g birth weight) and a control group of 60 randomly selected children >2499 g birth weight were studied. Children were assessed at 14 years of age. A paediatrician determined the clinical respiratory status. Lung function was measured according to standard guidelines. RESULTS: Of 180 preterm children seen at age 14, 42 (23%) had bronchopulmonary dysplasia (BPD) in the newborn period. Readmission to hospital for respiratory ill health was infrequent in all groups and the rates of asthma were similar (15% in the 500-999 g birth weight group, 21% in the 1000-1500 g birth weight group, 21% in controls; 19% BPD, 18% no BPD). Overall, lung function was mostly within the normal range for all cohorts; few children had lung function abnormalities in clinically significant ranges. However, the preterm children had significantly lower values for variables reflecting flow. Lung function in children of 500-999 g birth weight was similar to children of 1000-1500 g birth weight. Preterm children with BPD had significantly lower values for variables reflecting flow than children without BPD. CONCLUSIONS: The respiratory health of children of birth weight <1501 g at 14 years of age is comparable to that of term controls.  (+info)

Chronic pulmonary insufficiency in children and its effects on growth and development. (6/452)

Conditions leading to chronic pulmonary insufficiency can affect infants and children. These can lead to growth failure and delayed development. Among the most common and severe of these are bronchopulmonary dysplasia (BPD) and cystic fibrosis. In addition to the respiratory consequences of these diseases, there is ample evidence that they lead to decreased growth as a result of decreased energy intake and increased energy expenditure. Furthermore, there is evidence that infants with BPD may also have delayed development, independent of the effects of their prematurity. Enhancing the long-term outlook for these conditions may therefore require consideration of both improved pulmonary management and aggressive nutritional management to limit growth failure and potentially enhance developmental outcome. Specific micronutrient supplementation, such as antioxidant therapy, may also enhance pulmonary and nutritional status.  (+info)

Special nutritional needs of infants for prevention of and recovery from bronchopulmonary dysplasia. (7/452)

Extremely low birth weight infants who develop severe respiratory disease may have special nutrient requirements imposed by a combination of enhanced utilization of nutrients or the need for epithelial cell repair resulting from the disease process, as well as to support catch-up growth. Inositol, free fatty acids, vitamin E and vitamin A are proposed as nutrients for which infants at risk of chronic pulmonary insufficiency may have special requirements. Of these nutrients, only for vitamin A does suggestive evidence exist that high doses when given intramuscularly may reduce the incidence of death or chronic lung disease. Exogenous steroid therapy (dexamethasone), which is often used to improve pulmonary compliance in ventilated premature infants, may compromise vitamin A status and induce restricted somatic and bone mineral growth. Supplemental nutrition by means of enriched infant formulas has provided benefits in growth and bone mass accretion to infants recovering from bronchopulmonary dysplasia up to 3-mo corrected age. This growth advantage was not sustained over the subsequent 9 mo, suggesting that prolonged nutritional support is required until catch-up growth is complete. Further studies are required to delineate the needs for specific nutrients such as antioxidant vitamins and minerals or vitamin A that may play a role in preventing severe chronic lung disease in premature infants. As well, the role of supplemental nutrition (beyond the requirements of term infants) to support catch-up growth and maintenance during the critical stages of early development requires further investigation before evidence-based nutrient recommendations can be developed for this special population of infants.  (+info)

Is there a role for antioxidant therapy in bronchopulmonary dysplasia? (8/452)

Bronchopulmonary dysplasia (BPD) is a chronic lung disease first described in 1967 as a complication of therapy for premature infants with hyaline membrane disease, and treatment with high concentrations of oxygen was thought to be a major contributor to its development. Thus, interventions to enhance lung antioxidants to prevent the development of BPD were considered appropriate therapeutic strategies. In the last decades, advances in the acute care of premature infants has reduced the reliance on therapy with high concentrations of supplemental oxygen. However, the incidence of BPD has not changed significantly. The changing clinical context in which BPD develops begs the question of whether oxidation is important in the development of BPD and, therefore, whether designing interventions enhancing lung antioxidants is still warranted. This review presents evidence that premature infants that will develop BPD have qualitative and quantitative differences in oxidation of lipids and proteins when compared to infants that do not develop BPD. Such differences in oxidation patterns are the most obvious in the first few days of life. The emerging evidence thus supports the concept that the lung injury process leading to the development of BPD occurs within hours to days of delivery and that oxidation is a major contributor to this pathological process. Unfortunately, early attempts at delivery of antioxidants to the lung have not been successful, perhaps because of an inability to deliver antioxidants in a timely manner to the areas in the lung in which deleterious oxidations are occurring. Further research is necessary to determine both the nature and the location of the oxidative events that lead to the development of early lung injury, so that more appropriate and specific antioxidant interventions can be designed.  (+info)

The physiologic definition of BPD standardized the definition of BPD among centers and led to a reduction in the overall rate of BPD from 35% to 25%. Variation in rates of BPD among centers was reduced modestly, but significant variation among centers remained even when using the physiologic definition.. The clinical definition was assigned at 36 weeks and 0 days postmenstrual age, whereas the physiologic definition was assigned between 35 and 37 weeks postmenstrual age. The wider window of time allowed infants who were steadily weaning from oxygen to reach room air in the window and also ensured that infants were not studied during an acute deterioration. This wider window resulted in more infants reaching room air and thus being assigned the outcome "no BPD." Thus, the number assigned the clinical definition of BPD is greater than the sum of those on positive pressure support, oxygen, and failed physiologic challenge, as shown in Fig 1. The difference is clinically relevant, because the ...
Infants with severe bronchopulmonary dysplasia (BPD) have high risks of late morbidities and mortality, but the best ways to manage these vulnerable patients are still debated. In fact, its not always clear how to define "severe BPD".. The Bronchopulmonary Dysplasia Collaborative, a group of institutions led by Nationwide Childrens Hospital, has recently published a review to guide neonatologists - and to help the multidisciplinary teams that are crucial for a patients ongoing care.. "One of the focuses of neonatology has been on the prevention of BPD," says Leif Nelin, MD, chief of the Division of Neonatology at Nationwide Childrens and senior author of The Journal of Pediatrics review. "Thats very important. When the disease occurs, however, patients are often taken care of as if they have an acute disease, when they actually have a chronic one. And once the neonatal intensive care unit phase is over, care can ultimately fall to a pulmonologist, a critical care specialist, a cardiologist ...

A number of definitions of bronchopulmonary dysplasia (BPD), or chronic lung disease, have been used. A June 2000 National Institute of Child Health and Human Development/National Heart, Lung, and Blood Institute Workshop proposed a severity-based definition of BPD for infants ,32 weeks gestational age (GA). Mild BPD was defined as a need for supplemental oxygen (O2) for , or =28 days but not at 36 weeks postmenstrual age (PMA) or discharge, moderate BPD as O2 for , or =28 days plus treatment with ,30% O2 at 36 weeks PMA, and severe BPD as O2 for , or =28 days plus , or =30% O2 and/or positive pressure at 36 weeks PMA. The objective of this study was to determine the predictive validity of the severity-based, consensus definition of BPD. Data from 4866 infants (birth weight , or =1000 g, GA ,32 weeks, alive at 36 weeks PMA) who were entered into the National Institute of Child Health and Human Development Neonatal Research Network Very Low Birth weight (VLBW) Infant Registry between January ...
HYPOTHESIS:. Early prophylactic inhalation of Budesonide reduces the absolute risk of developing bronchopulmonary dysplasia (BPD) or death in preterm infants born ,28 weeks gestational age (GA) by 10%.. PRIMARY OBJECTIVE:. To determine whether inhalation of Budesonide within 12 hours of life improves survival without BPD at 36 weeks GA in infants born between 23 and 27 weeks GA.. SECONDARY OBJECTIVES:. To determine whether prophylactic inhalation of Budesonide affects neurodevelopment at a corrected age of 18-22 months in preterm infants; to determine whether inhalation of corticosteroids is associated with adverse treatment effects, alters mortality at 36 weeks GA, BPD incidence at 36 weeks GA, and the duration of positive pressure respiratory support or supplemental oxygen.. RATIONALE:. Pre- and postnatal exposure of the developing lung to inflammation is central to the development of BPD and the pulmonary inflammatory response in preterms at risk of developing BPD is established very early in ...
Bronchopulmonary dysplasia (BPD) is the most common chronic lung disease (CLD) in premature infants. This study was designed to elucidate the regulation of miRNA-547-3p on adrenomedullin (ADM) during the pathogenesis of BPD. We used Agilent Human 4x44K Gene Expression Microarrays v2 and miRCURY LNA™ microRNA Array to identify the differently expressed miRNA and its potential target genes, and certified them again by luciferase reporter gene analysis. We only retained target genes that met the following two conditions: first, coexisting in two databases, and second, expressing differences, and then identifying target genes by luciferase reporter gene analysis. Thus, we selected miRNA-574-3p and its target gene ADM for further research. We used real-time q-PCR to determine the expression of miRNA-574-3p and its target gene ADM in premature infants with BPD. We used microarray expression to analyze BPD samples and non-BPD samples and found that there were 516 differently expressed probes between ...
Aims: The aim of this study was to determine the incidence of neonatal morbidity in extremely preterm infants and to identify associated risk factors. Methods: Population based study of infants born before 27 gestational weeks and admitted for neonatal intensive care in Sweden during 2004-2007. Results: Of 638 admitted infants, 141 died. Among these, life support was withdrawn in 55 infants because of anticipation of poor long-term outcome. Of 497 surviving infants, 10% developed severe intraventricular haemorrhage (IVH), 5.7% cystic periventricular leucomalacia (cPVL), 41% septicaemia and 5.8% necrotizing enterocolitis (NEC); 61% had patent ductus arteriosus (PDA) and 34% developed retinopathy of prematurity (ROP) stage andgt;= 3. Eighty-five per cent needed mechanical ventilation and 25% developed severe bronchopulmonary dysplasia (BPD). Forty-seven per cent survived to one year of age without any severe IVH, cPVL, severe ROP, severe BPD or NEC. Tocolysis increased and prolonged mechanical ...
Studying neonatal Chronic Lung Disease in the preterm infant, also known as Bronchopulmonary Dysplasia, has led to pathophysiologic concepts which enable a more profound understanding of the disease and generate treatment strategies allowing for the improvement of structural and functional pulmonary outcome. Here, both clinical studies as well as animal models have cross-fertilized each other, translating the definition of clinical needs and the identification of important variables from bench to bedside and back. Elaborate animal models have been designed and refined following different aims reaching from the understanding of relevant pathways as well as the investigation of clinically meaningful treatment strategies. By the use of large study cohorts, significant relationships between risk factors and their confounders could be identified, impacting both research aims and clinical routine. First, following current topics in the field the research topic will enrich the knowledge and
Bronchopulmonary dysplasia is a chronic lung disease of premature neonates characterized by arrested pulmonary alveolar development. There is increasing evidence that microRNAs (miRNAs) regulate translation of messenger RNAs (mRNAs) during lung organogenesis. The potential role of miRNAs in the pathogenesis of BPD is unclear. Following exposure of neonatal mice to 80% O2 or room air (RA) for either 14 or 29 days, lungs of hyperoxic mice displayed histological changes consistent with BPD. Comprehensive miRNA and mRNA profiling was performed using lung tissue from both O2 and RA treated mice, identifying a number of dynamically regulated miRNAs and associated mRNA target genes. Gene ontology enrichment and pathway analysis revealed that hyperoxia modulated genes involved in a variety of lung developmental processes, including cell cycle, cell adhesion, mobility and taxis, inflammation, and angiogenesis. MiR-29 was prominently increased in the lungs of hyperoxic mice, and several predicted mRNA targets of
Bronchopulmonary dysplasia (BPD), also known as chronic lung disease (CLD), is one of the most challenging complications in premature infants. The incidence of BPD has been increasing over the past two decades in parallel with an improvement in the survival of this population. Furthermore, the clinical characteristics and the natural history of infants affected by BPD have changed considerably, and newer definitions to clarify the term BPD have also evolved since its first description more than four decades ago. Several drug therapies have also evolved, either to manage these infants respiratory distress syndrome with an aim to prevent BPD or to manage the established condition. Although there is good evidence to support the routine use of some therapies, many other therapies currently used in relation to BPD remain individual- or institution-specific, depending on beliefs and myths that we have adopted. In this article, we discuss the importance of defining BPD more objectively and the support--or
Babies who are born prematurely or who experience respiratory problems shortly after birth are at risk for bronchopulmonary dysplasia (BPD), sometimes called chronic lung disease.
Neonatal Chronic Lung Disease, i.e. Bronchopulmonary Dysplasia (BPD) is characterized by impaired pulmonary development. Triggered by different risk factors including infections, hyperoxia and mechanical ventilation of the immature lung, remodeling of the extracellular matrix, apoptosis as well as altered growth factor signaling characterize the disease. The immediate consequences have been studied in different animal models supported by in vitro approaches leading to the successful application of these findings to the clinical setting in the past. Nonetheless, existing information about long-term consequences of the identified early and most likely sustained changes to the developing lung is limited. Interesting results point towards a tremendous impact on the pulmonary repair capacity as well as aging related processes in the adult lung.

BACKGROUND The long-term effects on neurodevelopment of the use of inhaled glucocorticoids in extremely preterm infants for the prevention or treatment of bronchopulmonary dysplasia are uncertain. METHODS We randomly assigned 863 infants (gestational age, 23 weeks 0 days to 27 weeks 6 days) to receive early (within 24 hours after birth) inhaled budesonide or placebo. The prespecified secondary long-term outcome was neurodevelopmental disability among survivors, defined as a composite of cerebral palsy, cognitive delay (a Mental Development Index score of ,85 [1 SD below the mean of 100] on the Bayley Scales of Infant Development, Second Edition, with higher scores on the scale indicating better performance), deafness, or blindness at a corrected age of 18 to 22 months. RESULTS Adequate data on the prespecified composite long-term outcome were available for 629 infants. Of these infants, 148 (48.1%) of 308 infants assigned to budesonide had neurodevelopmental disability, as compared with 165 ...
There is animal evidence that inhaled nitric oxide (NO) reduces lung inflammation, improves surfactant function, attenuates hyperoxic lung injury, and promotes lung growth. It is hoped, therefore, that it might prevent bronchopulmonary dysplasia (BPD). Trials in preterm infants with respiratory failure have, however, given inconclusive results. Now two US multicentre trials have provided some support for treatment with inhaled NO.. In a 21-centre trial ...

OBJECTIVE: To determine the incidence of bronchopulmonary dysplasia, to identify maternal and neonatal factors associated with the disease, and to determine the correlation between bronchopulmonary dysplasia and the progress of newborns. METHODS: Data were prospectively collected on 153 infants born in Campinas (state of São Paulo, Brazil) from September 2000 to April 2002 weighing less than 1,500 g and treated at the University Hospital. The ratio of incidence rates with 95% CI, Breslow-Cox regression, Students t test, linear regression and the Fishers exact test were utilized. RESULTS: Among the 124 babies who survived until 28 days of age, 33 (26.6%) developed bronchopulmonary ...
Objective: Bronchopulmonary dysplasia (BPD) is a severe common complication of preterm birth with considerable short and long-term consequences. As more evidence is emerging that dysregulation of angiogenesis is implicated in the pathogenesis of preeclampsia as well as in fetal lung development, we assessed if preeclampsia is associated with development of BPD in very preterm neonates. Study design: A retrospective cohort study of 308 infants born between 24+0 and 31+6 weeks of gestation in 2011 and 2012. We performed association analysis with univariable and multivariable logistic regression, adjusting for confounders. Models were additionally adjusted for intermediates, to show how an association can be disguised by over adjusting. Main outcome measure: BPD was diagnosed at 36+0 weeks postmenstrual age and defined as the need for oxygen (FiO2 , 0.21) for at least 12 h per day, for more than 28 days before or at 36+0 weeks postmenstrual age, and classified as mild, moderate or severe. Results: ...
Understanding the role of susceptibility genes for risk of BPD and ROP may lead to immediate identification of populations who require personalized medical care, and to the assessment of innovative prophylactic and therapeutic interventions in the future. Our purpose is to establish in our hospital network a prospective cohort of triads composed of premature newborns with a birth weight less than or equal to 1250 g and their parents, to examine the role of candidate susceptibility genes in the development of BPD and ROP. Our hypothesis is that the presence of single-nucleotide polymorphisms in candidate genes is associated with differential susceptibility to BPD and ROP. As an initial model, a loss-of-function substitution at position -617 of the NRF2 promoter region is hypothesized to be associated with a greater risk of severe BPD and prethreshold ROP in premature infants with a birth weight less than or equal to 1250 g ...

BPD is caused by damage to the delicate tissue of the lungs. This damage is most often occurs in infants who have required extended treatment with supplemental oxygen or breathing assistance with a machine (mechanical ventilation) such as infants who are born prematurely and have acute respiratory distress syndrome.. When infants receive mechanical ventilation, a tube is inserted through the windpipe and the machine pushes air into the lungs, which are often underdeveloped in premature infants. In some cases, the levels of oxygen required for an affected infant to survive are higher than normally would be found in the air we breathe. Over time, the constant pressure from the ventilator and the excess oxygen levels can damage the delicate tissues of an infants lungs causing inflammation and scarring.. Although many cases of BPD are associated with mechanical ventilation or excess oxygen levels, BPD can arise from other conditions that affect the development of the lungs such as infection that ...
A chronic lung disease developed after OXYGEN INHALATION THERAPY or mechanical ventilation (VENTILATION, MECHANICAL) usually occurring in certain premature infants (INFANT, PREMATURE) or newborn infants with respiratory distress syndrome (RESPIRATORY DISTRESS SYNDROME, NEWBORN). Histologically, it is characterized by the unusual abnormalities of the bronchioles, such as METAPLASIA, decrease in alveolar number, and formation of CYSTS ...
Inflammation is the primary pathological process that precedes the development of BPD. Increased tracheal concentrations of inflammatory cytokines have been reported in infants who develop this disease [3-8]. Interleukin-4 and IL-13 have been shown to modulate lung inflammation in animal models and thus the presence or absence of these cytokines in the lung may be important determinants in the pathogenesis of BPD [16, 28].. Interleukin-4 is a pleiotropic cytokine produced predominately by T-lymphocytes and alveolar macrophages [10, 29]. Interleukin-4 stimulates production of some cytokines and growth factors while inhibiting others [11-17, 30]. Although IL-4 may be inhibitory to some aspects of lung inflammation, the presence of IL-4 may be detrimental by inducing proliferation of, and collagen production by, subsets of lung fibroblasts [31, 32]. Further, IL-4 is a central mediator in the development of asthma [20]. We detected very low concentrations of IL-4 in only one fifth of the tracheal ...

Introduction: Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects primarily preterm infants. Genetic factors are also taken into consideration in the pathogenesis of BPD. Genetic predispositions to higher production of inflammation mediators seem to be crucial. Material and methods: The aim of this study was to evaluate the possible relationship between polymorphisms: interleukin-1β +3953 C,T, interleukin-6 -174 G,C and -596 G,A, tumour necrosis factor -308 G,A and interleukin-1RN VNTR 86bp and the occurrence of BPD in a population of 100 preterm infants born from singleton pregnancy, before 32+0 weeks of gestation, exposed to antenatal steroids therapy, and without congenital abnormalities ...
Bronchopulmonary dysplasia is sometimes treated using glucocorticoids, a class of steroid hormone. Now, a large-scale study has investigated whether inhaling budesonide, a synthetic anti-inflammatory agent in the glucocorticoid family, has an effect on bronchopulmonary dysplasia and the survival of premature babies.. For the Neonatal European Study of Inhaled Steroids (NEUROSIS), 40 study centers across 9 countries enrolled 863 premature babies born before the 28th week of pregnancy. This makes NEUROSIS one of the largest ever randomized studies of premature babies to have been initiated in Europe. The lead scientist was Dirk Bassler from Tübingen, and the study was coordinated by Prof. Dr. Christian Poets, Director of the Department of Neonatology at University Childrens Hospital in Tübingen, Germany.. NEUROSIS was financed by European Union funding under the 7th framework program for research. "However, the study would not have been possible without the support of many families, committed ...

Infants born premature are at increased risk for development of bronchopulmonary dysplasia (BPD), pulmonary hypertension (PH), and ultimately right ventricular (RV) dysfunction, which together carry a high risk of neonatal mortality. However, the role alveolar simplification and abnormal pulmonary microvascular development in BPD affects RV contractile properties is unknown. We used a rat model of BPD to examine the effect of hyperoxia-induced PH on RV contractile properties. We measured in vivo RV pressure as well as passive force, maximum Ca(2+) activated force, calcium sensitivity of force (pCa50) and rate of force redevelopment (ktr) in RV skinned trabeculae isolated from hearts of 21-and 35-day old rats pre-exposed to 21% oxygen (normoxia) or 85% oxygen (hyperoxia) for 14 days after birth ...
Bronchopulmonary dysplasia (BPD) is a long-term lung condition that can affect some children with NRDS. It develops when the ventilator used to treat NRDS causes scarring to the lungs, which affects their development.. Symptoms of BPD include, rapid, shallow breathing and shortness of breath. Babies with severe BPD usually require additional oxygen from tubes into their nose to help with their breathing. This is usually stopped after a few months, when the lungs have healed.. However, children with BPD may require regular medication, such as bronchodilators, to help widen the airways of their lungs and assist with their breathing.. ...
While postnatal dexamethasone (dex) therapy ameliorates bronchopulmonary dysplasia (BPD) in preterm infants, it also increases rates of neuromotor and cognitive abnormalities. In a study by Murphy et al, dex therapy was associated with reduced cerebral cortical gray matter (GM) volumes as compared to untreated infants on volumetric MRI.1However, in that study, the impact of BPD was not considered as a confounder and dex therapy was given for a prolonged period (mean duration, 28 days). We evaluated brain component volumes in a cohort of extremely low birth weight infants (ELBW, BW ≤ 1000 g) discharged from our neonatal intensive care unit during a 7-month period, from June 2003 through December 2003. We hypothesized that dex therapy results in reduced combined cortical gray and white matter (WM) volume (cortical volume) with concomitant increased total cerebrospinal fluid (CSF) volume, at a given total brain volume. Of the 38 ELBW infants who survived to discharge, 37 had an anatomical brain ...

Chronic lung disease is the general term for long-term breathing problems in premature babies. Its also called bronchopulmonary dysplasia (BPD). Heres what you need ot know about this condition.
Bronchopulmonary dysplasia is sometimes treated with steroids to decrease scarring. Because steroids can cause side effects, doctors usually wait as long as possible to begin steroid treatment. Steroids are generally not used without a complete discussion with the family about potential benefits and risks.. Other, more commonly used medicines include diuretics (which make the baby urinate, or pee, and help eliminate excess fluid that can build up in the damaged lungs) and bronchodilators (which relax the muscles that surround the airways and allow them to open up).. Babies with BPD also sometimes need ventilators (breathing machines) at home to help them breathe. And although its not common, in severe cases the surgical insertion of a breathing tube in the neck (called a tracheostomy) may be done so the baby can go home on a ventilator. Some babies need home oxygen therapy for several months.. ...
Because CLD is a chronic disease and appears gradually, doctors must look at several factors. It is often diagnosed when a premature baby with respiratory problems continues to need additional oxygen after reaching 28 days old. Chest X-rays compared with previous X-rays may show changes in the appearance of the lungs. The X-ray of lungs with CLD often have a bubbly, sponge-like appearance. X-rays are diagnostic tests which use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film.. Blood tests (test used to determine if enough oxygen is in the blood) and an echocardiography (test that use sound waves to create images of the heart to rule out defects) are also used to confirm causes of bronchopulmonary dysplasia.. ...

Researchers suggest a possible cell-based therapy to stimulate lung development in fragile premature infants who suffer from a rare condition called Bronchopulmonary Dysplasia (BPD), which in the most severe cases can lead to lifelong breathing problems and even death. Scientists publish their preclinical findings report the American Journal of Respiratory and Critical Care Medicine.
Nevertheless, interobserver reliability had not been assessed. We selected comparisons among three birth-year periods instead of individual birth years to supply a sufficiently large sample to control for confounding inside our analysis and to provide mortality estimates with greater accuracy. We performed post hoc subgroup analyses to judge potential differences in general and immaturity-related mortality because of the addition and attrition of centers as time passes, and we performed sensitivity analyses to judge the consequences of potential misclassification of deaths because of immaturity, the respiratory distress syndrome, or bronchopulmonary dysplasia . Additional analyses examined factors behind death that were challenging by either CNS damage or infection for which another primary cause was listed.21, 2015 - - Children whove their tonsils eliminated to take care of sleep apnea are more likely to suffer breathing problems than kids whove the procedure for other reasons, a new review ...

Design: Prospective, blinded, controlled ...
Chronic lung disease (CLD) or bronchopulmonary dysplasia (BPD) is a disease of premature babies who required prolonged support with their breathing and supplemental oxygen. These babies are at high risk of many short and long-term problems with their breathing, growth and development, including death in infancy or childhood. Studies have shown that these babies have higher energy expenditure and lower energy intake compared with babies without CLD/BPD. Increasing energy intake for these babies beyond standard levels may therefore seem beneficial. However, setting high targets for energy intake for these babies may not be achievable. Furthermore, methods of increasing energy intake such as increasing the milk volume or concentration or giving intravenous nutrition may lead to complications of their own. We planned to examine whether increasing energy intake for these babies improves their breathing status, their growth and development, and reduces their risk of death without producing significant ...

My lab is interested in the normal developmental processes that build the lung and how such processes go awry during lung malformations, injury and tumorigenesis. What is unique about my lab is our effort to develop a series of three-dimensional labeling and imaging methods such as optical projection tomography. We develop these novel methods to address a major challenge in studying the lung - its complex three-dimensional architecture including the tree-like airways and honeycomb-like alveoli, making it difficult to compare structures on conventional two-dimensional sections. Development of the alveolar type 1 cell and bronchopulmonary dysplasia. Bronchopulmonary dysplasia (BPD) is a major chronic lung disease associated with preterm birth and characterized by alveolar simplification with dysmorphic microvasculature.

While progress has been made in the treatment and prevention of BPD, the prevalence has not decreased. Hydrocortisones mineralocorticoid and glucocorticoid properties are beneficial in decreasing inflammatory processes that may be harmful to the developing lung. Studies indicate that hydrocortisone improves BPD-free survival and may decrease ventilation time. Hydrocortisone appears to be a safer alternative to dexamethasone, which historically demonstrated efficacy in the prevention of BPD, but was associated with short- and long-term adverse effects that may outweigh its benefit. ...

Background: Bronchopulmonary dysplasia (BPD) is characterized by structural lung changes which may affect ventilation distribution. Volumetric capnography (VC) has been used in adults to provide information on ventilation homogeneity and ventilation-over-perfusion status. The aim of this study was to assess the value of VC in assessing ventilation homogeneity in infants with BPD.. Methods: Lung function (tidal breathing - multiple breath washout) parameters from 132 healthy infants (94 term, 38 preterm) and 66 infants with moderate or severe BPD were compared. Expiratory capnograms were obtained by mainstream capnography over 100 tidal breaths. The slopes of phases II (SII) and III (SIII) were calculated by linear regression on emprirically chosen intervals as follows: For SII between 5 and 60% of the end-expiratory CO2 fraction and for SIII between 40, 50, or 60 and 95% of the expiratory volume. The correlation between these indices and lung clearence index (LCI) was also assessed.. Results: ...
Bronchopulmonary dysplasia (BPD) is one of the most serious chronic lung diseases in infancy and one of the most important sequels of premature birth (prevalence of 15-50%). Our objective was to estimate the cost of BPD of one preterm baby, with no other major prematurity-related complications, during the first 2 years of life in Spain. Data from the Spanish Ministry of Health regarding costs of diagnosis-related group of preterm birth, hospital admissions and visits, palivizumab administration, and oxygen therapy in the year 2013 were analyzed. In 2013, 2628 preterm babies were born with a weight under 1500 g; 50.9% were males. The need for respiratory support was 2.5% needed only oxygen therapy, 39.5% required conventional mechanical ventilation, and 14.9% required high-frequency ventilation. The incidence of BPD was of 34.9%. The cost of the first 2 years of life of a preterm baby with BPD and no other major prematurity-related complications ranged between 45,049.81 and 118,760.43 , in Spain, ...

In the present study, we report that inhibition of PDE4s by rolipram in rabbit pups exposed to chorioamnionitis preserved antenatal and postnatal alveolarization, without modifying the inflammatory response. However, we observed marked intrauterine growth retardation and a very high incidence of stillbirth in animals treated with rolipram, results not yet reported in this model. Rolipram is the prototypical PDE4 selective inhibitor. PDEA4 enzyme is the main cAMP-metabolizing enzyme in immune and inflammatory cells, airway smooth muscle, and pulmonary nerves; its inhibition suppresses the recruitment and activation of several inflammatory cells (neutrophils, CD8 T cells, and macrophages) known to have a crucial role in the pathophysiological processes of bronchopulmonary dysplasia (Sanz et al., 2005; Hayes et al., 2010). In this context, we chose to test this new treatment in a previously described model of antenatal infection with subsequent impaired alveolarization in the rabbit (Gras-Le Guen ...
Cardiorespiratory function is not only the foremost determinant of life after premature birth, but also a major factor of long-term outcomes. However, the path from placental disconnection to nutritional autonomy is enduring and challenging for the preterm infant and, at each step, will have profound influences on respiratory physiology and disease. Fluid and energy intake, specific nutrients such as amino-acids, lipids and vitamins, and their ways of administration —parenteral or enteral—have direct implications on lung tissue composition and cellular functions, thus affect lung development and homeostasis and contributing to acute and chronic respiratory disorders. In addition, metabolomic signatures have recently emerged as biomarkers of bronchopulmonary dysplasia and other neonatal diseases, suggesting a profound implication of specific metabolites such as amino-acids, acylcarnitine and fatty acids in lung injury and repair, inflammation and immune modulation. Recent advances have
Results The total incidence of ROP was 11.94% and that of treatment-requiring ROP was 3.98%. Two patients with gestational age (GA) ,32 weeks and BW ,1500 g had treatment-requiring ROP. 15 eyes from eight infants with type I ROP required laser photocoagulation. The mean BWs and GAs in the treatment-requiring ROP group were significantly lower than those in the no or mild ROP group. Total duration of oxygen supplementation, surfactant usage, respiratory distress syndrome, bronchopulmonary dysplasia, antibiotic use for more than 14 days and the number of ROP-associated risk factors significantly increased the likelihood of treatment-requiring ROP (p=0.002, p=0.008, p=0.008, p=0.000, p=0.015, and p=0.004, respectively). ...
Introduction: Bronchopulmonary dysplasia (BPD) caused by prematurity is associated with more remodeling and fibrosis than asthma, yet symptoms and treatment of these two disorders are similar. The chitinase-like protein YKL-40, is a novel biomarker of asthma although the mechanisms involved are unknown. YKL-40 levels correlate with airway remodeling (Chupp et al. NEJM 2007) and YKL-40 increases smooth muscle proliferation (Bara et al. AJRCCM 2012). We aimed to compare serum YKL-40 in children with asthma and BPD.. Methods: Age- and sex-matched children with diagnosed asthma (n=27) or BPD (n=28) were included in the study at 10 yrs of age. Serum YKL-40 levels were measured by ELISA. ...
Results The preterm group had substantial impairments in airflow at both ages compared with controls (eg, mean differences in z-score for FEV1; 8 years −1.02, 95% CI −1.21 to −0.82; 18 years −0.92, 95% CI −1.14 to −0.71). The preterm group had a greater increase in small airway obstruction between 8 and 18 years compared with controls. Within the preterm group, those who had bronchopulmonary dysplasia in the newborn period and those who were smokers at 18 years had airway obstruction that increased over time compared with those who did not. ...

The effects of bronchial arterial administration of vasoactive substances on the pulmonary circulation were studied by a new technique for selective catheterization of a bronchial artery in intact dogs. In most experiments, this technique permitted pressor agents to be distributed mainly to one lung with smaller amounts to the other lung. The intercostal arteries were avoided, and in all but 2 of 23 experiments only microscopic quantities of injected India ink could be identified in the distribution of the esophageal and mediastinal branches. These studies indicate that serotonin, angiotensin, histamine, and norepinephrine injected selectively into a bronchial artery increase lobar arterial pressure. Since blood flow was constant and left atrial pressure did not change, the increase in pressure suggests active pulmonary vasoconstriction. Additionally, the responses to bronchial and lobar arterial injections of pressor agents were similar. The contribution of bronchopulmonary shunt flow to ...

Lung function and respiratory symptoms were studied in 40 children aged 8-18 years who had been ventilated for hyaline membrane disease after birth; 11 had had bronchopulmonary dysplasia. Also studied were 38 age matched children who had had hyaline membrane disease but had not required ventilation, 25 unmatched children who were born prematurely but did not develop hyaline membrane disease, and 39 randomly selected pupils of similar age. There was no difference in thoracic gas volume, total lung capacity, inspiratory vital capacity, residual volume, or transfer factor for carbon monoxide between the groups. Respiratory symptoms during the three years before the study and the frequency of clinically diagnosed asthma in patients and their family were similar in all the children with hyaline membrane disease irrespective of whether they had been ventilated or had had bronchopulmonary dysplasia. The children with bronchopulmonary dysplasia, however, had a lower forced expiratory volume in one ...
NEW YORK (Reuters Health) - Across many subgroups of preterm infants, high-frequency oscillatory ventilation (HFOV) and conventional ventilation are just as likely to prevent bronchopulmonary dysplasia, and they are equally safe, according to a meta-analysis published online June 1 in The Lancet.

Bronchopulmonary dysplasia (BPD) remains a major respiratory illness in extremely premature infants. The biological mechanisms leading to BPD are not fully understood, although an arrest in lung development has been implicated. The current study aimed to investigate the occurrence of autophagy in the developing mouse lung and its regulatory role in airway branching and terminal sacculi formation. We found 2 windows of epithelial autophagy activation in the developing mouse lung, both resulting from AMPK activation. Inhibition of AMPK-mediated autophagy led to reduced lung branching in vitro. Conditional deletion of beclin 1 (Becn1) in mouse lung epithelial cells (Becn1Epi-KO), either at early (E10.5) or late (E16.5) gestation, resulted in lethal respiratory distress at birth or shortly after. E10.5 Becn1Epi-KO lungs displayed reduced airway branching and sacculi formation accompanied by impaired vascularization, excessive epithelial cell death, reduced mesenchymal thinning of the interstitial ...

Although PDA is the most common cardiovascular lesion in EPNs and has been associated with a wide variety of important cardiac and noncardiac morbidities and even mortality (15-19), the treatment strategy for this lesion remains controversial (20). Current therapeutic options, particularly surgical ligation, have unacceptable morbidity, and surgical ligation may actually worsen long-term outcomes, including increasing the risk for bronchopulmonary dysplasia, retinopathy of prematurity, and neurosensory impairment (7,8). These concerns have resulted in a trend toward avoidance of definitive treatment and a movement toward a so-called permissive approach to PDA in EPNs, consisting of fluid restriction, diuretic agents, and increased positive end-expiratory pressure (21). Although several studies have reported outcomes no worse, and in some cases better, than with surgical ligation (22,23), more recent studies have associated this approach with increased mortality and morbidity (19,24). The lack of ...
CV delivers relatively large tidal volumes that can injure neonates lungs. HFOV uses rapid, small tidal volumes to avoid the large changes in lung volume. A systematic review of 6 randomised controlled trials (RCTs) comparing HFOV with CV showed that HFOV was associated with a reduction in chronic lung disease, but in 2 trials, it was also associated with an increase in brain injury.1 These studies have been criticised for using different strategies to optimise lung expansion, possibly confounding the result.. The RCT by Johnson et al is 1 of 2 large, recent trials comparing HFOV with CV. While Johnson et al found no differences, Courtney et al found that infants ventilated with HFOV had a small but significant increase in survival without bronchopulmonary dysplasia, and were successfully extubated 1 week earlier.2 Intracranial abnormalities were not increased in either trial. However, Courtney et al found that those treated with HFOV had lower rates of lung haemorrhage,2 whereas Johnson et al ...
Project 1. Ozone (O3) is a major component of air pollution and it has important detrimental health effects on humans. Moreover, as much as 40% of the U.S. population is estimated to be exposed to potentially harmful levels of O3. We previously identified significant linkage of O3-induced lung hyperpermeability and inflammation QTLs to chromosomes 4 and 17 (Inf2), respectively. Ongoing research in the EGG has addressed the hypotheses that gene(s) within the chromosome 4 QTL [e.g. toll-like receptor 4 (Tlr4)] and Inf2 [e.g. tumor necrosis factor alpha (Tnf)] modulate differential susceptibility to O3-induced injury and inflammation.. Project 2. Reactive oxygen species (ROS) have been implicated in the pathogenesis of many acute and chronic clinical disorders such as acute lung injury, bronchopulmonary dysplasia (BPD), and cancer. The transcription factor NF-E2, related factor 2 (Nrf2) was identified as a candidate susceptibility gene for hyperoxia-induced lung injury and inflammation in adult ...

Infants born very prematurely can require supplementary oxygen for many months. Rehospitalisation is common in the first 2 years after birth and the majority of admissions are for respiratory disorders. Rehospitalisation is particularly increased in infants with bronchopulmonary dysplasia (BPD) who require supplementary oxygen for more than 28 days after birth, and in infants who have a respiratory syncytial virus (RSV) lower respiratory tract infection (LRTI) (see chapter 16). Respiratory symptoms continue to be common in schoolchildren who were born prematurely, and the most severely affected remain symptomatic in adulthood; an adverse outcome that may be more common in females. Prematurely born infants, particularly those who wheeze at follow-up, have evidence of airway obstruction (raised airway resistance and gas trapping) in the first 2 years after birth. Their lung function improves with increasing age, but even in adolescence there is evidence of airflow limitation in those who had had ...

Despite advances in neonatal care over the past 2 decades, BPD remains a significant cause of morbidity and mortality in neonates. Recent literature from the National Institute of Child Health reviewing trends in neonatal care and outcomes among extremely low birth weight infants (ELBWs) showed a significant improvement in the survival to discharge of preterm ELBWs, but this was accompanied by an increase in BPD rates [28]. While this increase in BPD rates could be secondary to the improved survival of ELBWs, therapies for BPD have remained elusive and survivors have significantly higher rates of motor, cognitive and behavioral impairment [29].. Interestingly, emerging evidence now suggests that IT administration of MSCs may regenerate the injured preterm lung. Pre-clinical studies, including those performed in our laboratory, demonstrate that IT MSCs improve alveolar and vascular development, reverse PH and improve pulmonary vascular remodeling in experimental models of BPD [8, 9]. In a seminal ...

The laboratory and clinical investigation of exogenous pulmonary surfactant therapy for respiratory distress syndrome (RDS) in preterm infants is one of the most comprehensive therapeutic adventures in neonatal medicine of this decade. Mortality in the very low birth weight infant with RDS clearly has improved along with a reduction in the incidence of pulmonary interstitial emphysema, pneumothorax, and bronchopulmonary dysplasia.. One issue that remains unresolved is the use of surfactant as prophylaxis versus rescue therapy in infants with established disease. Installation before or at the initiation of respiration is no longer believed to be essential for successful intrapulmonary distribution or clinical response; however, early treatment of infants with RDS may be beneficial.. Clearly, gestational age and birth weight are directly related to endogenous surfactant production. However, multiple variables including maternal steroid administration, duration of ruptured membranes, amniotic fluid ...
