pulmicort and Bronchopulmonary-Dysplasia

Survival from even very premature birth is improving, but long-term respiratory morbidity following neonatal chronic lung disease (bronchopulmonary dysplasia (BPD)) has not reduced. Affected infants may require supplementary oxygen at home, because they have more hospital admissions particularly due to viral infections and frequent, troublesome respiratory symptoms requiring treatment. Furthermore, adolescents and adults who had BPD have poorer lung function and exercise capacity.. Antenatal and postnatal preventative strategies and management of infants with BPD. A literature review was undertaken using PubMed and Web of Science.. There are effective preventative strategies which include caffeine, postnatal corticosteroids, vitamin A, and volume guarantee ventilation. Side-effects, however, have appropriately caused clinicians to reduce use of systemically administered corticosteroids to infants only at risk of severe BPD. Promising preventative strategies which need further research are surfactant with budesonide, less invasive surfactant administration (LISA), neurally adjusted ventilatory assist (NAVA) and stem cells. The management of infants with established BPD is under-researched and should include identifying the optimum form of respiratory support on the neonatal unit and at home and which infants will most benefit in the long term from pulmonary vasodilators, diuretics, and bronchodilators.

To address the effectiveness and safety of early airway combined utilization of budesonide and surfactant for bronchopulmonary dysplasia (BPD) prevention in premature infants with respiratory distress syndrome (RDS).. Literature retrieval was carried out in the PubMed, Web of Science, EMBASE, Cochrane Library, Wanfang, CQ VIP, and China National Knowledge Infrastructure databases, searching from the inception to September 2021. Stata 16.0 software was used for statistical analysis.. This meta-analysis suggested that early combined utilization of budesonide and surfactant by airway have a superiority on BPD incidence (risk ratio [RR] = 0.62; 95% confidence interval [CI]: 0.54-0.71, p < 0.001], mortality (RR = 0.64; 95%CI: 0.45-0.92, p = 0.016), the composite outcome of BPD or mortality (RR = 0.58; 95%CI: 0.50-0.68, p < 0.001), the additional doses of surfactant (RR = 0.53; 95%CI: 0.44-0.63, p < 0.001), the duration of assisted ventilation (standard mean difference [SMD] = -1.14; 95%CI: -1.58 to -0.70, p < 0.001), duration of invasive ventilation(SMD = -1.77; 95% CI: -2.61 to -0.93, p < 0.001), and hospital stays (SMD = -1.11; 95% CI: -1.73 to -0.49, p = 0.001) in preterm infants with RDS. And these benefits were not associated with increased adverse outcomes. Furthermore, a decreased incidence of patent ducts arterious (PDA) (RR = 0.79; 95% CI: 0.65 to 0.97, p = 0.028) was found in premature infants treated with budesonide and surfactant. Subgroup analysis based on budesonide delivery methods (inhalation or intratracheal instillation) indicated that the decrease of mortality (RR = 0.63; 95% CI: 0.43-0.93, p = 0.019), duration of assisted ventilation (SMD = -0.95; 95% CI: -1.30 to -0.61, p < 0.001), hospital stays (SMD = -1.23; 95% CI: -2.05 to -0.41, p = 0.003) and PDA incidence (RR = 0.80; 95% CI: 0.65 to 0.99, p = 0.044) were mainly in budesonide intratracheal instillation subgroup, rather than in budesonide inhalation subgroup.. This meta-analysis suggested that early combined utilization of budesonide and surfactant by airway might be an effective and safe clinical practice for BPD prevention in premature infants with RDS, especially when budesonide was delivered by intratracheal instillation. However, many of the included studies were small and were from Asian origin. More well-designed randomized controlled trials with larger sample sizes and longer follow-up from all over the world ought to be conducted in the future.

Despite advances in neonatal intensive care in the recent decade, a large number of very preterm infants (VPIs) remain at risk for significant neurodevelopmental impairment (NDI). Given that there are many interventions need to be implemented during the critical perinatal period so that complications of these vulnerable VPIs could be minimized, it is urgent to develop multi-discipline strategies based on evidence to be carried out. The objective of this new term evidence-based perinatal critical strategies (EBPCS), is to provide beneficial intervention towards better neurodevelopmental outcomes, specifically for preterm infants below 28 weeks gestational age. EBPCS is defined as the management of the VPIs during the perinatal period which would include antenatal counseling with team briefing and share decision making, treat the chorioamnionitis, antenatal MgS04, antenatal steroid, delayed cord clamping/milking, neonatal resuscitation team preparation, prevention of hypothermia, immediate respiratory support with continuous positive airway pressure at delivery room, less invasive surfactant administration, early surfactant with budesonide therapy, support of cardiovascular system, early initiate of probiotics administration, early caffeine, early parenteral and enteral nutrition, promptly initiating antibiotics. These critical strategies will be discussed detail in the text; nonetheless, standardized protocols, technical skills and repeated training are the cornerstones of successful of EBPCS. Further experience from different NICU is needed to prove whether these very complicate and comprehensive perinatal critical strategies could translate into daily practice to mitigate the incidence of NDI in high-risk VPIs.

Bronchopulmonary dysplasia (BPD) is a major complication of premature birth that significantly affects mortality and long-term morbidity in numerous immature infants. Corticosteroids are particularly suitable for treating BPD, as lung inflammation is central to its pathogenesis. Corticosteroids have considerable, fast beneficial effects on lung function in premature infants with lung disease, but they are also associated with several serious adverse effects, which may have a detrimental impact on long-term outcome. Dexamethasone is the most often used corticosteroid for systemic administration. Despite its value in preventing and treating BPD, its use is associated with several alarming short-term effects and, worst of all, with an increased rate of cerebral palsy in the long term. Dexamethasone nonetheless remains an important therapeutic option for infants with severe lung disease beyond the second to third week of life. Hydrocortisone is an important alternative to dexamethasone, as its use does not appear to be associated with any neurotoxic effects. Its efficacy in the prevention and treatment of BPD has yet to be clearly demonstrated, however. Inhaled corticosteroids might reduce lung inflammation with fewer systemic adverse effects; however, a recent, large randomized trial showed that inhaled budesonide was associated with an excess mortality, despite its beneficial respiratory effects. In another study, instilling budesonide together with surfactant in the trachea of intubated infants with severe respiratory distress appeared safe and achieved a significant reduction in the rate of BPD at 36 postmenstrual weeks. This important finding needs to be confirmed in a larger trial currently underway.

Bronchopulmonary dysplasia (BPD) remains the most common respiratory morbidity in immature infants. This review describes the diagnosis of BPD has evolved and summarises the therapeutic approaches that have made it possible to limit the incidence of BPD.. We reviewed the literature from the first definition of BPD by Northway in 1967 to the surfactant treatment policies that are currently in use, drawing on more than 50 papers up to 2017.. Our review showed that improvements in neonatal survival have been associated with an increased risk of severe BPD, significant levels of long-term morbidity and the increased use of healthcare resources. These issues have encouraged researchers to explore potential new treatments that limit the incidence of BPD. Repeated surfactant instillation and the use of surfactant as a vehicle for budesonide are promising strategies for alleviating the burden of chronic lung disease. Ongoing research on surfactant or stem cell therapy may further improve the respiratory prognosis for prematurely born children.. Considerable research has been carried out into the increase in BPD, which has resulted from improvements in neonatal survival. Key areas of research include repeated surfactant administration, using surfactant as a vehicle for budesonide and stem cell therapy.

Bronchopulmonary dysplasia (BPD), defined as oxygen dependence at 36 weeks postmenstrual age (PMA), remains an important complication of prematurity. Pulmonary inflammation plays a central role in the pathogenesis of BPD. Attenuating pulmonary inflammation with postnatal systemic corticosteroids reduces the incidence of BPD in preterm infants but may be associated with an increased risk of adverse neurodevelopmental outcomes. Local administration of corticosteroids via inhalation might be an effective and safe alternative.. To determine if administration of inhalation corticosteroids after the first week of life until 36 weeks PMA to preterm infants at high risk of developing BPD is effective and safe in reducing the incidence of death and BPD as separate or combined outcomes.. We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2017, Issue 4), MEDLINE via PubMed (1966 to 19 May 2017), Embase (1980 to 19 May 2017), and CINAHL (1982 to 19 May 2017). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.. We included randomised controlled trials comparing inhalation corticosteroids, started ≥ 7 days postnatal age (PNA) but before 36 weeks PMA, to placebo in ventilated and non-ventilated infants at risk of BPD. We excluded trials investigating systemic corticosteroids versus inhalation corticosteroids.. We collected data on participant characteristics, trial methodology, and inhalation regimens. The primary outcome was death or BPD at 36 weeks PMA. Secondary outcomes were the combined outcome death or BPD at 28 days PNA, the seperate outcomes of death and BPD at both 28 days PNA, and at 36 weeks PMA, and short-term respiratory outcomes, such as failure to extubate; total days of mechanical ventilation and oxygen use; and the need for systemic corticosteroids. We contacted the original trialists to verify the validity of extracted data and to provide missing data. We analysed all data using Review Manager 5. When possible, we performed meta-analysis using typical risk ratio (RR) for dichotomous outcomes and weighted mean difference (WMD) for continuous outcomes along with their 95% confidence intervals (CI). We analysed ventilated and non-ventilated participants separately.We used the GRADE approach to assess the quality of the evidence.. We included eight trials randomising 232 preterm infants in this review. Inhalation corticosteroids did not reduce the separate or combined outcomes of death or BPD. The meta-analyses of the studies showed a reduced risk in favor of inhalation steroids regarding failure to extubate at seven days (typical RR (TRR) 0.80, 95% CI 0.66 to 0.98; 5 studies, 79 infants) and at the latest reported time point after treatment onset (TRR 0.60, 95% CI 0.45 to 0.80; 6 studies, 90 infants). However, both analyses showed increased statistical heterogeneity (I. Based on the results of the currently available evidence, inhalation corticosteroids initiated at ≥ 7 days of life for preterm infants at high risk of developing BPD cannot be recommended at this point in time. More and larger randomised, placebo-controlled trials are needed to establish the efficacy and safety of inhalation corticosteroids.

Bronchopulmonary dysplasia (BPD) remains an important cause of mortality and morbidity in preterm infants and inflammation plays a significant role in its pathogenesis. The use of inhaled corticosteroids may modulate the inflammatory process without concomitant high systemic steroid concentrations and less risk of adverse effects. This is an update of a review published in 2012 (Shah 2012). We recently updated the related review on "Inhaled versus systemic corticosteroids for treating bronchopulmonary dysplasia in ventilated very low birth weight preterm neonates".. To determine the effect of inhaled versus systemic corticosteroids started within the first 7 days of life on preventing death or BPD in ventilated very low birth weight infants.. We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2017, Issue 1), MEDLINE via PubMed (1966 to 23 February 2017), Embase (1980 to 23 February 2017), and CINAHL (1982 to 23 February 2017). We searched clinical trials registers, conference proceedings and the reference lists of retrieved articles for randomised controlled trials (RCTs) and quasi-randomised trials.. Randomised or quasi-randomised controlled trials comparing inhaled versus systemic corticosteroid therapy (irrespective of dose and duration) starting in the first seven days of life in very low birth weight preterm infants receiving assisted ventilation.. Clinical outcomes data were extracted and analysed using Review Manager. When appropriate, meta-analysis was performed using typical relative risk (RR), typical risk difference (RD) and weighted mean difference (WMD). Meta-analyses were performed using typical relative risk, typical risk difference (RD), and weighted mean difference with their 95% confidence intervals (CI). If RD was statistically significant, the number needed to benefit or the number needed to harm was calculated. We assessed the quality of evidence was evaluated using GRADE principles.. We included two trials that involved 294 infants. No new studies were included for the 2017 update. The incidence of death or BPD at 36 weeks' postmenstrual age was not statistically significantly different between infants who received inhaled or systemic steroids (RR 1.09, 95% CI 0.88 to 1.35; RD 0.05, 95% CI -0.07 to 0.16; 1 trial, N = 278). The incidence of BPD at 36 weeks' postmenstrual age among survivors was not statistically significant between groups (RR 1.34, 95% CI 0.94 to 1.90; RD 0.11, 95% CI -0.02 to 0.24; 1 trial, N = 206). There was no statistically significant difference in the outcomes of BPD at 28 days, death at 28 days or 36 weeks' postmenstrual age and the combined outcome of death or BPD by 28 days between groups (2 trials, N = 294). The duration of mechanical ventilation was significantly longer in the inhaled steroid group compared with the systemic steroid group (typical MD 4 days, 95% CI 0.2 to 8; 2 trials, N = 294; I² = 0%) as was the duration of supplemental oxygen (typical MD 11 days, 95% CI 2 to 20; 2 trials, N = 294; I² = 33%).The incidence of hyperglycaemia was significantly lower with inhaled steroids (RR 0.52, 95% CI 0.39 to 0.71; RD -0.25, 95% CI -0.37 to -0.14; 1 trial, N = 278; NNTB 4, 95% CI 3 to 7 to avoid 1 infant experiencing hyperglycaemia). The rate of patent ductus arteriosus increased in the group receiving inhaled steroids (RR 1.64, 95% CI 1.23 to 2.17; RD 0.21, 95% CI 0.10 to 0.33; 1 trial, N = 278; NNTH 5, 95% CI 3 to 10). In a subset of surviving infants in the United Kingdom and Ireland there were no significant differences in developmental outcomes at 7 years of age. However, there was a reduced risk of having ever been diagnosed as asthmatic by 7 years of age in the inhaled steroid group compared with the systemic steroid group (N = 48) (RR 0.42, 95% CI 0.19 to 0.94; RD -0.31, 95% CI -0.58 to -0.05; NNTB 3, 95% CI 2 to 20).According to GRADE the quality of the evidence was moderate to low. Evidence was downgraded on the basis of design (risk of bias), consistency (heterogeneity) and precision of the estimates.Both studies received grant support and the industry provided aero chambers and metered dose inhalers of budesonide and placebo for the larger study. No conflict of interest was identified.. We found no evidence that early inhaled steroids confer important advantages over systemic steroids in the management of ventilator-dependent preterm infants. Based on this review inhaled steroids cannot be recommended over systemic steroids as a part of standard practice for ventilated preterm infants. Because they might have fewer adverse effects than systemic steroids, further randomised controlled trials of inhaled steroids are needed that address risk/benefit ratio of different delivery techniques, dosing schedules and long-term effects, with particular attention to neurodevelopmental outcome.

Uncertainly prevails with regard to the use of inhalation or instillation steroids to prevent bronchopulmonary dysplasia in preterm infants. The meta-analysis with sequential analysis was designed to evaluate the efficacy and safety of airway administration (inhalation or instillation) of corticosteroids for preventing bronchopulmonary dysplasia (BPD) in premature infants.. We searched MEDLINE, EMBASE, CINAHL, and Cochrane CENTRAL from their inceptions to February 2017. All published randomized controlled trials (RCTs) evaluating the effect of airway administration of corticosteroids (AACs) vs placebo or systemic corticosteroid in prematurity were included. All meta-analyses were performed using Review Manager 5.3.. Twenty five RCTs retrieved (n = 3249) were eligible for further analysis. Meta-analysis and trial sequential analysis corrected the 95% confidence intervals estimated a lower risk of the primary outcome of BPD (relative risk 0.71, adjusted 95% confidence interval 0.57-0.87) and death or BPD (relative risk 0.81, adjusted 95% confidence interval 0.71-0.97) in AACs group than placebo and it is equivalent for preventing BPD than systemic corticosteroids. Moreover, AACs fail to increasing risk of death compared with placebo (relative risk 0.90, adjusted 95% confidence interval 0.40-2.03) or systemic corticosteroids (relative risk 0.81, 95% confidence interval 0.62-1.06).. Our findings suggests that AACs (especially instillation of budesonide using surfactant as a vehicle) are an effective and safe option for preventing BPD in preterm infants. Furthermore, the appropriate dose and duration, inhalation or instillation with surfactant as a vehicle and the long-term safety of airway administration of corticosteroids needs to be assessed in large trials.

Theoretically, administration of inhaled corticosteroids may allow for beneficial effects on the pulmonary system of infants with evolving or established bronchopulmonary dysplasia (BPD) with a lower risk of undesirable side effects compared to systemic corticosteroids. However, before deciding whether to use inhaled corticosteroids for BPD in routine clinical practice, the available randomized study data need to be considered. Currently published systematic reviews from the Cochrane Collaboration conclude that there is no role for inhaled corticosteroids in neither prevention nor treatment of BPD outside clinical trials. In contrast multiple observational studies indicate that a large number of preterm infants in Europe, North America and East Asia receive inhaled corticosteroids for this indication in routine clinical care. This discrepancy between evidence and practice prompted a large randomized controlled trial (RCT) investigating the role of inhaled budesonide for the prevention of BPD which was recently published and showed a significant reduction in the incidence of BPD. However, the primary outcome (a composite of death or BPD at 36 weeks postmenstrual age) was only of borderline significance as a result of a non-significant trend to increased mortality in the budesonide group. Results of the long-term follow up from this study should be considered when defining the future role of inhaled corticosteroids for BPD. Additionally, updated systematic reviews will help to determine whether the observed mortality difference between the two comparison groups represents truth or artifact.

Despite the near universal adaptation of gentle mechanical ventilation, surfactant use and non-invasive respiratory support, bronchopulmonary dysplasia (BPD) remains one of the most common respiratory morbidities in very low birth weight (VLBW) infants. Thus, the objective of this review was to evaluate the efficacy of intra-tracheal administration of budesonide-surfactant mixture in preventing bronchopulmonary dysplasia (BPD) in very low birth weight (VLBW) infants. MEDLINE, EMBASE, and PubMed were searched for randomized clinical trials in which intra-tracheal administration of budesonide-surfactant was used to prevent BPD in infants. The primary outcomes were BPD and composite outcome of death or BPD. Meta-analysis of the two clinical trials revealed that infants who received intra-tracheal instillation of budesonide-surfactant mixture demonstrated 43% reduction in the risk of BPD (RR: 0.57; 95%CI: 0.43-0.76, NNT = 5). Although mortality was not different between the groups (OR: 0.61; 95%CI: 0.34-1.04), a 40% reduction was observed in the composite outcome of death or BPD in the budesonide-surfactant group (RR: 0.60; 95%CI: 0.49-0.74, NNT = 3). Thus, this review concludes that intra-tracheal administration of budesonide-surfactant combination was associated with decreased incidence of BPD alone or composite outcome of death or BPD in VLBW infants though there is a need for larger trials before it can be recommended as a standard of care.

Survival of extremely preterm infants has increased over recent years, but bronchopulmonary dysplasia (BPD) remains a major cause of morbidity. In the USA, BPD is the most common chronic respiratory disorder of infancy and affects the pulmonary and overall health of 10,000 preterm infants annually. Preclinical and clinical studies suggest a crucial role for lung inflammation and host immune response in the pathogenesis of BPD. Inflammation may result from, amongst others, chorioamnionitis, postnatal infection, ventilation, and the administration of oxygen. Infants with BPD have worse long-term outcomes than those without chronic lung disease. They are more than twice as likely to be readmitted to hospital in their first year of life and, having survived their primary hospitalizations, they are more likely to die than very preterm infants without chronic lung disease. Survivors with BPD have an increased risk of neurodevelopmental impairment and their respiratory function remains compromised well into adolescence. As the first generations of extremely low birth weight (ELBW) survivors have not yet reached retirement age, there are currently no reliable data addressing the association between BPD and pulmonary diseases of the elderly such as chronic obstructive pulmonary disease. Although BPD is quite common in ELBW infants, there are infants who do not develop BPD, which supports the argument that BPD is a preventable disease, emphasizing the need for high-quality safety and efficacy prevention studies. However, according to an Institute of Medicine statement regarding pediatric drug studies, the therapeutic area that has the fewest drugs indicated for neonates is BPD. As inflammation seems to be a primary mediator of injury in the pathogenesis of BPD, anti-inflammatory agents such as steroids have long been the focus of preventive research activities. However, systemic steroids, although reducing BPD, have frequently been linked to adverse neurodevelopmental outcomes and these considerations may have contributed to the recently reported widespread use of inhaled corticosteroids in neonatal units in North America and Europe. Inhaled corticosteroids were prescribed to 25% of infants born at <29 weeks of gestation with birth weights <1,500 g in neonatal units of 35 children's hospitals in the USA. According to a survey across all neonatal units in Germany, 46% administered inhaled corticosteroids to preterm infants either as prophylaxis or treatment for BPD

Bronchopulmonary dysplasia (BPD), defined as oxygen dependence at 36 weeks postmenstrual age (PMA), remains an important complication of prematurity. Pulmonary inflammation plays a central role in the pathogenesis of BPD. Attenuating pulmonary inflammation with postnatal systemic corticosteroids reduces the incidence of BPD in preterm infants but may be associated with an increased risk of adverse neurodevelopmental outcomes. Local administration of corticosteroids via inhalation might be an effective and safe alternative.. To determine if administration of inhalation corticosteroids after the first week of life to preterm infants at high risk of developing BPD is effective and safe in reducing the incidence of death and BPD as separate or combined outcomes.. We identified randomised, controlled trials by searching the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), PubMed (from 1966), EMBASE (from 1974), CINAHL (from 1982), references from retrieved trials and handsearches of journals, all assessed to February 2012.. Randomised controlled trials comparing inhalation corticosteroids, started ≥ 7 days postnatal age (PNA) but before 36 weeks PMA, to placebo in ventilated and non-ventilated infants at risk of BPD were included. Trials investigating systemic corticosteroids versus inhalation corticosteroids were excluded.. Data on patient characteristics, trial methodology, and inhalation regimens were collected. The primary outcomes were death or BPD, or both, at 28 days PNA or 36 weeks PMA. Secondary outcomes were short-term respiratory outcomes, such as failure to extubate, total days of mechanical ventilation and oxygen use, and the need for systemic corticosteroids. The original trialists were contacted to verify the validity of extracted data and to provide missing data. All data were analysed using RevMan 5.0.24. When possible, meta-analysis was performed using typical risk ratio (TRR) for dichotomous outcomes and weighted mean difference (WMD) for continuous outcomes along with their 95% confidence intervals (CI). Ventilated and non-ventilated participants were analysed separately.. Eight trials randomising 232 preterm infants were included in this review. Inhalation corticosteroids did not reduce the separate or combined outcomes of death or BPD. Furthermore, inhalation steroids did not impact short-term respiratory outcomes such as failure to extubate and total duration of mechanical ventilation or oxygen dependency. There was a trend to a reduced use of systemic corticosteroids in favour of inhalation corticosteroids (TRR 0.51; 95% CI 0.26 to 1.00). There was a paucity of data on short-term and long-term adverse effects. These results should be interpreted with caution because the total number of randomised patients is relatively small and most trials differed considerably in patient characteristics, inhalation therapy and outcome definitions.. Based on the results of the currently available evidence, inhalation corticosteroids initiated at ≥ 7 days of life for preterm infants at high risk of developing BPD cannot be recommended at this point in time. More and larger randomised, placebo-controlled trials are needed to establish the efficacy and safety of inhalation corticosteroids.

Inflammation plays a major role in the pathogenesis of bronchopulmonary dysplasia of preterm infants. Having a strong anti-inflammatory effect, corticosteroids have been proposed in the management of this disease. Antenatal steroids protect the newborn against its development. Postnatal systemic administration of steroids reduces the duration of mechanical ventilation and oxygen therapy, but is associated with short term and long term adverse effects. Early administration of dexamethasone (before 7 days of life) reduces the incidence and the severity of chronic lung disease at 28 days of life and 36 weeks of post-conceptional age. Inhaled steroids are associated with less adverse effects than dexamethasone administration, but they are also less effective.

Bronchopulmonary dysplasia (BPD), an inflammatory-mediated chronic lung disease, is common in extremely preterm infants born before 28 weeks' gestation and is associated with an increased risk of adverse neurodevelopmental and respiratory outcomes in childhood. Effective and safe prophylactic therapies for BPD are urgently required. Systemic corticosteroids reduce rates of BPD in the short-term but are associated with poorer neurodevelopmental outcomes if given to ventilated infants in the first week after birth. Intratracheal administration of corticosteroid admixed with exogenous surfactant could overcome these concerns by minimizing systemic sequelae. Several small, randomized trials have found intratracheal budesonide in a surfactant vehicle to be a promising therapy to increase survival free of BPD.. An international, multicenter, double-blinded, randomized trial of intratracheal budesonide (a corticosteroid) mixed with surfactant for extremely preterm infants to increase survival free of BPD at 36 weeks' postmenstrual age (PMA; primary outcome). Extremely preterm infants aged < 48 h after birth are eligible if: (1) they are mechanically ventilated, or (2) they are receiving non-invasive respiratory support and there is a clinical decision to treat with surfactant. The intervention is budesonide (0.25 mg/kg) mixed with poractant alfa (200 mg/kg first intervention, 100 mg/kg if second intervention), administered intratracheally via an endotracheal tube or thin catheter. The comparator is poractant alfa alone (at the same doses). Secondary outcomes include the components of the primary outcome (death, BPD prior to or at 36 weeks' PMA), potential systemic side effects of corticosteroids, cost-effectiveness, early childhood health until 2 years of age, and neurodevelopmental outcomes at 2 years of age (corrected for prematurity).. Combining budesonide with surfactant for intratracheal administration is a simple intervention that may reduce BPD in extremely preterm infants and translate into health benefits in later childhood. The PLUSS trial is powered for the primary outcome and will address gaps in the evidence due to its pragmatic and inclusive design, targeting all extremely preterm infants regardless of their initial mode of respiratory support. Should intratracheal budesonide mixed with surfactant increase survival free of BPD, without severe adverse effects, this readily available intervention could be introduced immediately into clinical practice..

The intervention is budesonide (0.25 mg/kg) mixed with poractant alfa (200 mg/kg first intervention, 100 mg/kg if second intervention), administered intratracheally via an endotracheal tube or thin catheter. The comparator is poractant alfa alone (at the same doses). Secondary outcomes include the components of the primary outcome (death, BPD prior to or at 36 weeks' PMA), and potential systemic side effects of corticosteroids. Longer-term outcomes will be published separately, and include cost-effectiveness, early childhood health until 2 years of age, and neurodevelopmental outcomes at 2 years of age (corrected for prematurity).. A sample size of 1038 infants (519 in each group) is required to provide 90% power to detect a relative increase in survival free of BPD of 20% (an absolute increase of 10%), from the anticipated event rate of 50% in the control arm to 60% in the intervention (budesonide) arm, alpha error 0.05. To allow for up to 2% of study withdrawals or losses to follow-up, PLUSS aimed to enroll a total of 1060 infants (530 in each arm). The binary primary outcome will be reported as the number and percentage of infants who were alive without BPD at 36 weeks' PMA for each randomization group. To estimate the difference in risk (with 95% CI), between the treatment and control arms, binary regression (a generalized linear multivariable model with an identity link function and binomial distribution) will be used. Along with the primary outcome, the individual components of the primary outcome (death, and physiological BPD at 36 weeks' PMA), will be reported by randomization group and, again, binary regression will be used to estimate the risk difference between the two treatment groups for survival and physiological BPD at 36 weeks' PMA.

To study the efficacy and safety of early intratracheal administration of budesonide combined with pulmonary surfactant (PS) in preventing bronchopulmonary dysplasia (BPD).. A prospective randomized controlled trial was designed. A total of 122 infants with a high risk of BPD who were admitted to the neonatal intensive care unit of the Third Affiliated Hospital of Zhengzhou University from January to July 2021 were enrolled. The infants were randomly divided into a conventional treatment group with 62 infants (treated with PS alone at an initial dose of 200 mg/kg, followed by a dose of 100 mg/kg according to the condition of the infant) and an observation group with 60 infants (treated with PS at the same dose as the conventional treatment group, with the addition of budesonide 0.25 mg/kg for intratracheal instillation at each time of PS application). The two groups were compared in terms of the times of PS use, ventilator parameters at different time points, oxygen inhalation, incidence rate and severity of BPD, incidence rate of complications, and tidal breathing pulmonary function at the corrected gestational age of 40 weeks.. Compared with the conventional treatment group, the observation group had a significantly lower proportion of infants using PS for two or three times (. Compared with PS use alone in preterm infants with a high risk of BPD, budesonide combined with PS can reduce repeated use of PS, lower ventilator parameters, shorten the duration of respiratory support, and reduce the incidence rate and severity of BPD, without increasing the incidence rate of glucocorticoid-related complications.

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.. 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.. 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 (51.4%) of 321 infants assigned to placebo (relative risk, adjusted for gestational age, 0.93; 95% confidence interval [CI], 0.80 to 1.09; P=0.40). There was no significant difference in any of the individual components of the prespecified outcome. There were more deaths in the budesonide group than in the placebo group (82 [19.9%] of 413 infants vs. 58 [14.5%] of 400 infants for whom vital status was available; relative risk, 1.37; 95% CI, 1.01 to 1.86; P=0.04).. Among surviving extremely preterm infants, the rate of neurodevelopmental disability at 2 years did not differ significantly between infants who received early inhaled budesonide for the prevention of bronchopulmonary dysplasia and those who received placebo, but the mortality rate was higher among those who received budesonide.

Inhaled glucocorticoids may increase the risk of pneumonia in adults. Thus, respiratory infections may be a potential explanation for the non-significantly increased mortality seen in the glucocorticoid group in the largest randomized trial on inhaled glucocorticoids for preventing bronchopulmonary dysplasia in preterm infants published to date (NEuroSIS).. To evaluate the effect of inhaled budesonide on the risk of death due to respiratory infections in the NEuroSIS trial.. We performed post hoc analyses of prospectively collected data from 856 preterm infants on presumed but not culture-proven sepsis and antimicrobial drug use. Additionally, pulmonary complications reported on adverse event forms, death certificates and autopsy reports were compared between study groups.. Treatment groups did not differ in the number of episodes with suspected sepsis (184/437 [42.1%] in the budesonide vs. 171/419 [40.8%] in the placebo group). Neither the number of patients receiving antimicrobial drugs nor the length of antimicrobial treatment differed between groups. Our analyses for pulmonary adverse events as well as for pulmonary complications reported on death certificates and autopsy reports did not suggest a negative impact of inhaled budesonide on these outcomes.. The current analysis does not support the assumption that respiratory tract infections explain the increased mortality seen in the glucocorticoid group in the NEuroSIS trial.

Bronchopulmonary dysplasia (BPD) is an important complication of mechanical ventilation in preterm infants, and no definite therapy can eliminate this complication. Pulmonary inflammation plays a crucial role in its pathogenesis, and glucocorticoid is one potential therapy to prevent BPD.. To compare the effect of intratracheal administration of surfactant/budesonide with that of surfactant alone on the incidence of death or BPD.. A clinical trial was conducted in three tertiary neonatal centers in the United States and Taiwan, in which 265 very-low-birth-weight infants with severe respiratory distress syndrome who required mechanical ventilation and inspired oxygen (fraction of inspired oxygen, ≥50%) within 4 hours of birth were randomly assigned to one of two groups (131 intervention and 134 control). The intervention infants received surfactant (100 mg/kg) and budesonide (0.25 mg/kg), and the control infants received surfactant only (100 mg/kg), until each infant required inspired O2 at less than 30% or was extubated.. The intervention group had a significantly lower incidence of BPD or death (55 of 131 [42.0%] vs. 89 of 134 [66%]; risk ratio, 0.58; 95% confidence interval, 0.44-0.77; P < 0.001; number needed to treat, 4.1; 95% confidence interval, 2.8-7.8). The intervention group required significantly fewer doses of surfactant than did the control group. The intervention group had significantly lower interleukin levels (IL-1, IL-6, IL-8) in tracheal aspirates at 12 hours and lower IL-8 at 3-5 and 7-8 days.. In very-low-birth-weight infants with severe respiratory distress syndrome, intratracheal administration of surfactant/budesonide compared with surfactant alone significantly decreased the incidence of BPD or death without immediate adverse effect. Clinical trial registered with www.clinicaltrials.gov (NCT-00883532).

To study the efficacy of different preparations of budesonide combined with pulmonary surfactant (PS) in improving blood gas levels and preventing bronchopulmonary dysplasia (BPD) in preterm infants with neonatal respiratory distress syndrome (NRDS).. A total of 184 preterm infants who developed NRDS within 4 hours after birth were randomly administered with PS + continuous inhalation of budesonide aerosol (continuous aerosol group), PS+budesonide solution (solution group), PS + single inhalation of budesonide aerosol (single aerosol group), and PS alone, with 46 neonates in each group. The changes in arterial blood gas levels, rate of invasive mechanical ventilation after treatment, time of assisted ventilation, rate of repeated use of PS, and the incidence of BPD were compared between the four groups.. On the 2nd to 4th day after treatment, pH, PCO2, and oxygenation index (FiO2/PaO2) showed significant differences among the four groups, and the continuous aerosol group showed the most improvements of all indicators, followed by the solution group, single aerosol group, and PS alone group. The continuous aerosol group had a significantly shorter time of assisted ventilation than the other three groups (P<0.05). The solution group had a significantly shorter time of assisted ventilation than the single aerosol and PS alone groups (P<0.05). The rate of invasive mechanical ventilation after treatment, rate of repeated use of PS, and incidence of BPD showed significant differences among the four groups (P<0.05), and the continuous aerosol group had the lowest rates, followed by the solution group.. A combination of PS and continuous inhalation of budesonide aerosol has a better efficacy in the treatment of NRDS than a combination of PS and budesonide solution. The difference in reducing the incidence of BDP between the two administration methods awaits further investigation with a larger sample size.

Systemic glucocorticoids reduce the incidence of bronchopulmonary dysplasia among extremely preterm infants, but they may compromise brain development. The effects of inhaled glucocorticoids on outcomes in these infants are unclear.. We randomly assigned 863 infants (gestational age, 23 weeks 0 days to 27 weeks 6 days) to early (within 24 hours after birth) inhaled budesonide or placebo until they no longer required oxygen and positive-pressure support or until they reached a postmenstrual age of 32 weeks 0 days. The primary outcome was death or bronchopulmonary dysplasia, confirmed by means of standardized oxygen-saturation monitoring, at a postmenstrual age of 36 weeks.. A total of 175 of 437 infants assigned to budesonide for whom adequate data were available (40.0%), as compared with 194 of 419 infants assigned to placebo for whom adequate data were available (46.3%), died or had bronchopulmonary dysplasia (relative risk, stratified according to gestational age, 0.86; 95% confidence interval [CI], 0.75 to 1.00; P=0.05). The incidence of bronchopulmonary dysplasia was 27.8% in the budesonide group versus 38.0% in the placebo group (relative risk, stratified according to gestational age, 0.74; 95% CI, 0.60 to 0.91; P=0.004); death occurred in 16.9% and 13.6% of the patients, respectively (relative risk, stratified according to gestational age, 1.24; 95% CI, 0.91 to 1.69; P=0.17). The proportion of infants who required surgical closure of a patent ductus arteriosus was lower in the budesonide group than in the placebo group (relative risk, stratified according to gestational age, 0.55; 95% CI, 0.36 to 0.83; P=0.004), as was the proportion of infants who required reintubation (relative risk, stratified according to gestational age, 0.58; 95% CI, 0.35 to 0.96; P=0.03). Rates of other neonatal illnesses and adverse events were similar in the two groups.. Among extremely preterm infants, the incidence of bronchopulmonary dysplasia was lower among those who received early inhaled budesonide than among those who received placebo, but the advantage may have been gained at the expense of increased mortality.

To compare early (<3 days) with late (>15 days) steroid therapy and dexamethasone with inhaled budesonide in very preterm infants at risk of developing chronic lung disease.. Five hundred seventy infants from 47 neonatal intensive care units were enrolled. Criteria for enrollment included gestational age <30 weeks, postnatal age <72 hours, and need for mechanical ventilation and inspired oxygen concentration >30%. Infants were randomly allocated to 1 of 4 treatment groups in a factorial design: early (<72 hours) dexamethasone, early budesonide, delayed selective (>15 days) dexamethasone, and delayed selective budesonide. Dexamethasone was given in a tapering course beginning with 0.50 mg/kg/day in 2 divided doses for 3 days reducing by half until 12 days of therapy had elapsed. Budesonide was administered by metered dose inhaler and a spacing chamber in a dose of 400 microg/kg twice daily for 12 days. Delayed selective treatment was started if infants needed mechanical ventilation and >30% oxygen for >15 days. The factorial design allowed 2 major comparisons: early versus late treatment and systemic dexamethasone versus inhaled budesonide. The primary outcome was death or oxygen dependency at 36 weeks and analysis was on an intention-to-treat basis. Secondary outcome measures included death or major cerebral abnormality, duration of oxygen treatment, and complications of prematurity. Adverse effects were also monitored daily.. There were no significant differences among the groups for the primary outcome. Early steroid treatment was associated with a lower primary outcome rate (odds ratio [OR]: 0.85; 95% confidence interval [CI]: 0.61,1.18) but even after adjustment for confounding variables the difference remained nonsignificant. Dexamethasone-treated infants also had a lower primary outcome rate (OR: 0.86; 95% CI: 0.62,1.20) but again this difference remained not significant after adjustment. For death before discharge, dexamethasone and early treatment had worse outcomes than budesonide and delayed selective treatment (OR: 1.42; 95% CI: 0.93,2.16; OR: 1.51; 95% CI: 0.99,2.30 after adjustment, respectively) with the results not quite reaching significance. Duration of supplementary oxygen was shorter in the early dexamethasone group (median: 31 days vs 40-44 days). Early dexamethasone was also associated with increased weight loss during the first 12 days of treatment (52 g vs 3 g) compared with early budesonide, but over 30 days there was no difference. In the early dexamethasone group, there was a reduced incidence of persistent ductus arteriosus (34% vs 52%-59%) and an increased risk of hyperglycemia (55% vs 29%-34%) compared with the other 3 groups. Dexamethasone was associated with an increased risk of hypertension and gastrointestinal problems compared with budesonide but only the former attained significance.. Infants given early treatment and dexamethasone therapy had improved survival without chronic lung disease at 36 weeks compared with those given delayed selective treatment and inhaled budesonide, respectively, but results for survival to discharge were in the opposite direction; however, none of these findings attained statistical significance. Early dexamethasone treatment reduced the risk of persistent ductus arteriosus. Inhaled budesonide may be safer than dexamethasone, but there is no clear evidence that it is more or less effective.

The speed of action and side-effects of systemic verus inhaled steroids was compared in infants with mild-moderate oxygen dependency. Forty infants (median gestational age 27 weeks) were randomized to receive either 10 days of dexamethasone (systemic group) or budesonide (100 micrograms qds) (inhaled group). At randomization, there was no significant difference in the gestational or postnatal age, inspired oxygen requirements or compliance of the respiratory system of the two groups. After 36 h of treatment, there were significant changes (P < 0.01) in both the inspired oxygen concentration and compliance of the respiratory system in the systemic but not the inhaled group. Only after 1 week of inhaled therapy were improvements in respiratory status noted but, even at that time, the inspired oxygen requirement was significantly lower in the systemic versus the inhaled group. In the systemic group only, however, were there significant increases in blood pressure.. Systemically administered rather than inhaled steroids appear to have a faster onset of action.

To determine if extremely preterm (EPT) neonates receiving dexamethasone for the prevention of BPD have a higher incidence of presumed adrenal insufficiency (PAI).. Retrospective cohort study of neonates <28 weeks gestation examining PAI after dexamethasone use and PAI after intratracheal budesonide with surfactant administration.. Of 332 neonates, 38% received dexamethasone. The incidence of PAI was higher in neonates who had received dexamethasone (20.8% vs 2.9%, p < 0.001). However, for intubated babies receiving surfactant, dexamethasone was not independently associated with increased PAI after adjusting for gestational age, birthweight, and race (aOR 2.92, 95% CI: 0.79-10.85). Dexamethasone was independently associated with increased PAI in infants previously receiving budesonide/surfactant treatment (aOR 5.38, 95% CI: 1.38-20.90).. The use of dexamethasone alone was not associated with increased PAI, when adjusted for prematurity-related factors. The combination of budesonide with dexamethasone was significantly associated with increased PAI.

The combination of surfactant and budesonide has been shown to decrease BPD rates and severity. Budesonide may be released systemically from lungs, and the effects on the immature adrenal glands are not known.. The aim of this study was to determine if adrenal suppression rates are higher in preterm infants receiving budesonide with surfactant compared to surfactant alone.. A retrospective chart review of 608 infants ≤1,250 g received intubation for surfactant therapy from 2013 through 2020. In August 2016, budesonide was added to surfactant for these infants. Indicators of adrenal suppression, including mean blood pressures, plasma electrolyte levels, hydrocortisone use, and the use of vasoactive medications, were analyzed for the first 14 days after birth. Respiratory variables, biochemical signs of adrenal insufficiency, and neonatal morbidities were analyzed.. There was no difference in hydrocortisone administration in the first 14 days between infants receiving budesonide with surfactant (n = 314) or surfactant alone (n = 294) (23% vs. 19%, p = 0.38). Budesonide exposed infants received hydrocortisone 3 days later than surfactant only infants (median DOL 5 vs. 2, p < 0.001). Infants receiving budesonide had higher blood pressures, required less dopamine (19% vs. 39%, p < 0.001) and dobutamine (2% vs. 6%, p = 0.02). Budesonide exposed infants were discharged home after a shorter NICU stay (85 days vs. 94 days, p = 0.02) and at a younger gestational age (39 vs. 40 weeks, p = 0.001).. The use of surfactant and budesonide does not alter the rate of hydrocortisone use, but does delay the timing of treatment initiation and decreases the use of vasoactive medications.

Describe the population of babies who do and do not receive postnatal corticosteroids for prevention or treatment of bronchopulmonary dysplasia (BPD).. Retrospective cohort study using data held in the National Neonatal Research Database.. National Health Service neonatal units in England and Wales.. Babies born less than 32 weeks gestation and admitted to neonatal units from 1 January 2012 to 31 December 2019.. Proportion of babies given postnatal corticosteroid; type of corticosteroid; age at initiation and duration, trends over time.. Survival to discharge, treatment for retinopathy of prematurity, BPD, brain injury, severe necrotising enterocolitis, gastrointestinal perforation.. 8% (4713/62019) of babies born <32 weeks and 26% (3525/13527) born <27 weeks received postnatal corticosteroids for BPD. Dexamethasone was predominantly used 5.3% (3309/62019), followed by late hydrocortisone 1.5%, inhaled budesonide 1.5%. prednisolone 0.8%, early hydrocortisone 0.3% and methylprednisolone 0.05%. Dexamethasone use increased over time (2012: 4.5 vs 2019: 5.8%, p=0.04). Median postnatal age of initiation of corticosteroid course was around 3 weeks for late hydrocortisone, 4 weeks for dexamethasone, 6 weeks for inhaled budesonide, 12 weeks for prednisolone and 16 weeks for methylprednisolone. Babies who received postnatal corticosteroids were born more prematurely, had a higher incidence of comorbidities and a longer length of stay.. In England and Wales, around 1 in 12 babies born less than 32 weeks and 1 in 4 born less than 27 weeks receive postnatal corticosteroids to prevent or treat BPD. Given the lack of convincing evidence of efficacy, challenges of recruiting to and length of time taken to conduct randomised controlled trial, our data highlight the need to monitor long-term outcomes in children who received neonatal postnatal corticosteroids.

Chorioamnionitis is associated with increased rates of bronchopulmonary dysplasia (BPD) in ventilated preterm infants. Budesonide when added to surfactant decreased lung and systemic inflammation from mechanical ventilation in preterm lambs and decreased the rates and severity of BPD in preterm infants. We hypothesized that the addition of budesonide to surfactant will decrease the injury from mechanical ventilation in preterm lambs exposed to intra-amniotic (IA) lipopolysaccharide (LPS).. Lambs at 126 ± 1 day GA received LPS 10 mg IA 48 h prior to injurious mechanical ventilation. After 15 min, lambs received either surfactant mixed with: (1) saline or (2) Budesonide 0.25 mg/kg, then ventilated with normal tidal volumes for 4 h. Injury markers in the lung, liver, and brain were compared.. Compared with surfactant alone, the addition of budesonide improved blood pressures, dynamic compliance, and ventilation, while decreasing mRNA for pro-inflammatory cytokines in the lung, liver, and multiple areas of the brain. LPS caused neuronal activation and structural changes in the brain that were not altered by budesonide. Budesonide was not retained within the lung beyond 4 h.. In preterm lambs exposed to IA LPS, the addition of budesonide to surfactant improved physiology and markers of lung and systemic inflammation.. The addition of budesonide to surfactant decreases the lung and systemic responses to injurious mechanical ventilation preterm lambs exposed to fetal LPS. Budesonide was present in the plasma by 15 min and the majority of the budesonide is no longer in the lung at 4 h of ventilation. IA LPS and mechanical ventilation caused structural changes in the brain that were not altered by short-term exposure to budesonide. The budesonide dose of 0.25 mg/kg being used clinically seems likely to decrease lung inflammation in preterm infants with chorioamnionitis.

To compare the efficacy of intra-tracheal (IT) surfactant/budesonide (SB) with that of surfactant alone (S) in reducing the rate of bronchopulmonary dysplasia (BPD) at 36 weeks post-menstrual age (PMA), we included extremely preterm very low birth weight (VLBW) infants with severe respiratory distress syndrome (RDS) in our tertiary neonatal level of care unit (Padua, Italy).. The preliminary results of this retrospective study suggest that in extremely preterm VLBW infants, IT SB for severe RDS did not affect the incidence of BPD, death, and BPD or death at 36 weeks PMA, compared to surfactant alone. The combined therapy proved to be safe in this population. Further studies are warranted to explore the role of early IT steroids on respiratory morbidity in preterm infants.

The addition of budesonide to surfactant in very-low-birth-weight infants with less severe RDS decreased bronchopulmonary dysplasia (BPD) severity. Long-term neurodevelopmental follow-up was needed to monitor for systemic effects of budesonide.. Infants ≤1250 g who received intratracheal budesonide (0.25 mg/kg) with surfactant (n = 173) were compared to a historical cohort who received surfactant alone (n = 294). Peabody Developmental Motor Scales II at 4-6 months corrected age and Bayley Scales of Infant & Toddler Development III at 18-22 months corrected age were compared.. There were no differences in muscle tone or motor skills by Peabody exam. There were no differences in the cognitive, language, or motor domains between cohorts on Bayley III.. In a cohort of infants treated with budesonide mixed with surfactant, there were no differences in developmental outcomes at 4-6 months or 18-22 months corrected age.

In preterm infants on moderately high ventilator support, the addition of budesonide to surfactant lowered bronchopulmonary dysplasia (BPD) rates by 20% without increased morbidity or mortality. The aim of this cohort comparison was to determine the safety and efficacy of the combination in infants with milder respiratory distress syndrome (RDS).. In August 2016 we began administering budesonide (0.25 mg/kg) mixed with surfactant (Survanta 4 mL/kg) to all infants ≤ 1250 g who failed CPAP and required intubation. Infants were compared to a historical cohort (2013-2016) who received surfactant alone.. BPD or death did not change between the historical surfactant cohort (71%, n = 294) and the budesonide cohort (69%, n = 173). Budesonide was associated with a decrease in the need for continued mechanical ventilation, severe BPD type II or death (19-12%), grade III BPD or death (31-21%), and the median gestational age at discharge was 1 week earlier. Histologic chorioamnionitis was associated with decreased budesonide effects. Secondary morbidities (NEC, IVH, ROP, Sepsis) were similar.. Overall BPD rates remained unchanged with the addition of budesonide. Budesonide was associated with decreased severity of BPD, decreased mechanical ventilation use, earlier discharge, and similar short-term outcomes.

Initial trials of lung-targeted budesonide (0.25 mg/kg) in surfactant to prevent bronchopulmonary dysplasia (BPD) in premature infants have shown benefit; however, the optimal safe dose is unknown.. Dose-escalation study of budesonide (0.025, 0.05, 0.10 mg/kg) in calfactatant in extremely low gestational age neonates (ELGANs) requiring intubation at 3-14 days. Tracheal aspirate (TA) cytokines, blood budesonide concentrations, and untargeted blood metabolomics were measured. Outcomes were compared with matched infants receiving surfactant in the Trial Of Late SURFactant (TOLSURF).. Twenty-four infants with mean gestational age 25.0 weeks and 743 g birth weight requiring mechanical ventilation were enrolled at mean age 6 days. Budesonide was detected in the blood of all infants with a half-life of 3.4 h. Of 11 infants with elevated TA cytokine levels at baseline, treatment was associated with sustained decrease (mean 65%) at all three dosing levels. There were time- and dose-dependent decreases in blood cortisol concentrations and changes in total blood metabolites. Respiratory outcomes did not differ from the historic controls.. Budesonide/surfactant had no clinical respiratory benefit at any dosing levels for intubated ELGANs. One-tenth the dose used in previous trials had minimal systemic metabolic effects and appeared effective for lung-targeted anti-inflammatory action.

Respiratory distress syndrome (RDS) is a major cause of early postnatal death in preterm infants. Bronchopulmonary dysplasia (BPD) is one of the most fatal chronic respiratory complications of preterm infants after management of RDS. Anti-inflammatory therapy with corticosteroid is one of the effective treatments to prevent BPD. However, systemic administration of corticosteroid is not recommended because of long-term adverse effects. We studied the effect of early intratracheal instillation of budesonide with surfactant in preterm infants with severe RDS.. Very low birth weight infants (VLBWIs) weighing less than 1,500 g who were admitted to the neonatal intensive care unit (NICU) of Busan Paik Hospital between January 2018 and December 2018 and diagnosed with severe RDS were enrolled. The treatment group was given a mixture of budesonide and surfactant (calfactant) while the control group was given surfactant (calfactant) only.. Surfactant re-dosing, duration of mechanical ventilation, BPD, mortality, and retinopathy of prematurity (≥ stage 2) were not different between the two groups though there were decreasing trends in the treatment group compared to those in the control group. The duration of hospital stay was longer in the control group with statistical significance.. Early intratracheal administration of budesonide with surfactant in preterm infants with severe RDS might decrease BPD and mortality without disturbing surfactant function. Further studies with different preparations of surfactants with a large number of preterm infants are required.

This study aimed to evaluate effect of budesonide combining Poractant Alfa on preventing bronchopulmonary dysplasia (BPD).. A total of 120 preterm infants were involved. pH value, partial pressure of oxygen (PO2), and blood gas analysis were evaluated. Peripheral blood was collected and mononuclear cells were isolated. Reactive oxygen species (ROS) in peripheral blood mononuclear cells (PBMCs) were detected with laser confocal. Sirtuin 1 (SIRT1) in PBMCs was detected using immunofluorescence. SIRT1 and small ubiquitin-like modifier (SUMO)-specific protease 1 (SENP1) were detected with Western blot.. Compared with group B, pH value and PO2 were improved significantly in group C and D (p<0.01). Compared with group B, oxygen inhalation duration, rate of having a respirator assisted ventilation, and using pulmonary surfactant (PS) again, and BPD incidence were significantly decreased in other groups (p<0.05). BPD incidence in group D was less than group C (χ2=4.00, p<0.05). Compared with control group, ROS level of neonatal respiratory distress syndrome (NRDS) group was significantly increased, SENP1 was increased, and SIRT1 was decreased in SIRT1 group. Compared with NRDS, when budesonide combined with Poractant Alfa, ROS decreased, SENP1 decreased, SIRT1 nuclear pulp shuttling rate reduced, nuclear SIRT1 increased (p<0.01). Compared with control, ROS level of NRDS group was significantly increased, SENP1 increased, and SIRT1 in nucleus decreased (p<0.05). Compared with NRDS group, when treated with budesonide and Poractant Alfa, ROS levels decreased, SENP1 decreased, nuclear SIRT1 increased (p<0.01).. Budesonide combining Poractant Alfa can prevent BPD in preterm infants by activating the SIRT1 signaling pathway.

Budesonide is a potential therapeutic option for the prevention of bronchopulmonary dysplasia in mechanically ventilated premature neonates. The dose and concentrations of budesonide that drive effective prophylaxis are unknown, due in part to the difficulty in obtaining serial blood samples from this fragile population. Of primary concern is the limited total blood volume available for collection for the purposes of a pharmacokinetic study. Dried blood spots (DBS), which require the collection of <200 μL whole blood to fill an entire card, are an attractive low-blood volume alternative to traditional venipuncture sampling. We describe a simple and sensitive method for determining budesonide concentrations in DBS using an ultra-high-performance liquid chromatography - tandem mass spectrometry assay. Budesonide was liberated from a single 6 mm punch using a basified methyl tert-butyl ether extraction procedure. The assay was determined to be accurate and precise in the dynamic range of 1 to 50 ng/mL. The validated assay was then successfully applied to DBS collected as part of a multi-center, dose-escalation study of budesonide administered in surfactant via intra-tracheal instillation to premature neonates between 23 and 28 weeks gestational age. These findings show that DBS are a useful technique for collecting pharmacokinetic samples in premature neonates and other pediatric populations.

BackgroundThe intratracheal (IT) administration of budesonide using surfactant as a vehicle has been shown to reduce the incidence of bronchopulmonary dysplasia (BPD) in preterm infants. The objective of this study was to characterize the in vitro characteristics and in vivo safety and efficacy of the extemporaneous combination of budesonide and poractant alfa.MethodsThe stability, minimum surface tension, and viscosity of the preparation were evaluated by means of high-performance liquid chromatography (HPLC), Wilhelmy balance, and Rheometer, respectively. The safety and efficacy of the IT administration of the mixture were tested in two respiratory distress syndrome (RDS) animal models: twenty-seventh day gestational age premature rabbits and surfactant-depleted adult rabbits.ResultsA pre-formulation trial identified a suitable procedure to ensure the homogeneity and stability of the formulation. Wilhelmy Balance tests clarified that budesonide supplementation has no detrimental effect on poractant alfa surface tension activity. The addition of budesonide to poractant alfa did not affect the physiological response to surfactant treatment in both RDS animal models, and was associated to a significant reduction of lung inflammation in surfactant-depleted rabbits.ConclusionOur in vitro and in vivo analysis suggests that the IT administration of a characterized extemporaneous combination of poractant alfa and budesonide is a safe and efficacious procedure in the context of RDS.

To explore the clinical efficacy of intratracheal instillation of pulmonary surfactant (PS) combined with budesonide for preventing bronchopulmonary dysplasia (BPD) in very low birth weight (VLBW) infants.. Thirty VLBW infants with gestational age <32 weeks who developed neonatal respiratory distress syndrome (NRDS) (grade III-IV) suffering from intrauterine infection were randomly assigned into a PS + budesonide group and a PS alone group. The changes were compared between the two groups in arterial blood gas indexes, oxygenation index (OI), duration of mechanical ventilation, duration of oxygen supplementation, incidence of BPD, mortality rate at 36 weeks corrected gestational age and incidences of other complications except BPD.. Compared with the PS alone group, the PS+budesonide group had a lower incidence of BPD, shorter duration of mechanical ventilation and oxygen supplementation (P<0.05). On the 2nd to 6th day after treatment, the PS+budesonide group had higher pH value of arterial blood gas and OI and lower carbon dioxide partial pressure compared with the PS alone group (P<0.05). There were no significant differences in the mortality rate at 36 weeks corrected gestational age and the incidences of other complications except BPD between the two groups (P>0.05).. Intratracheal instillation of PS combined with budesonide can effectively reduce the incidence of BPD in VLBW premature infants with severe NRDS.

To determine demographic and clinical variables associated with inhaled corticosteroid administration and to evaluate between-hospital variation in inhaled steroid use for infants with bronchopulmonary dysplasia (BPD).. Retrospective Cohort Study.. Neonatal units of 35 US children's hospitals; as recorded in the Pediatric Health Information System (PHIS) database.. 1429 infants with evolving BPD at 28 days who were born at <29 weeks gestation with birth weight <1500 grams, admitted within the first 7 postnatal days, and discharged between January 2007-June 2011.. Inhaled steroids were prescribed to 25% (n = 352) of the cohort with use steadily increasing during the first two months of hospitalization. The most frequently prescribed steroid was beclomethasone (n = 194, 14%), followed by budesonide (n = 125, 9%), and then fluticasone (n = 90, 6%). Birth gestation <24 weeks, birth weight 500-999 grams, and prolonged ventilation all increased the adjusted odds of ever receiving inhaled corticosteroids (p<0.05). Wide variations between hospitals in the frequency of infants ever receiving inhaled steroids (range: 0-60%) and the specific drug prescribed were noted. This variation persisted, even after controlling for observed confounders.. Inhaled corticosteroid administration to infants with BPD is common in neonatal units within U.S. Children's hospitals. However, its utilization varies markedly between centers from no treatment at some institutions to the majority of infants with BPD being treated at others. This supports the need for further research to identify the benefits and potential risks of inhaled steroid usage in infants with BPD.

In 1999, 80% of French neonatal centers used corticosteroids, mainly betamethasone (BMT), to prevent or treat bronchopulmonary dysplasia (BPD) [Lee SK, McMillan DD, Ohlson A, et al. Variations in practice and outcomes in the canadian NICU Network 1996-1997. Pediatrics 2000;106:1070-9]. As many data suggested a low risk-benefit ratio, an updated assessment of this use was necessary [Desnoulez L, Empana J, Anceschi M, et al. Prise en charge de l'immaturité pulmonaire en néonatologie : enquête sur les pratiques européennes. Arch Pediatr 2005;12:4-9; Halliday HL, Ehrenkranz RA, Doyle LW.

The effects of early postnatal dexamethasone therapy on pulmonary outcome in premature infants with respiratory distress syndrome: a 2-year follow-up study. Acta Paediatr 2005;94:310-16].. Questionnaires addressing the use of and indications for corticosteroids were sent to all French neonatal centers.. The study was conducted over 5 months (July to November 2006). Of 202 questionnaires sent out, 186 (92%) were completed. Of these 186 centers, 147 (79%) had a standard protocol for corticosteroid use, covering systemic and inhaled steroids (76 units), only systemic steroid therapy (30 units) and only inhaled steroids (41 units). Systemic corticosteroids were used in 106 centers for hemodynamic purposes in 42 cases (40%), prevention of BPD in 1 case (1%), early treatment of BPD (day 4 to day 21) in 23 cases (22%) and late treatment of BPD (after day 21) in 74 cases (70%). Hemisuccinate hydrocortisone (HSHC) was the only corticoid used for hemodynamic failure. The steroid used for early treatment of BPD was BMT (21 out of 23). The duration of treatment was less than 4 days in 10 centers (43%). The steroid most often used for late treatment was BMT (67 out of 74). The duration of treatment was less than 4 days in 29 centers, between 4 and 8 days in 22 centers, and longer than 8 days in 26 centers. Among 117 centers administering corticosteroids by inhalation, 74% used budesonide. Use of corticosteroids was higher in teaching hospitals (86%) than in others (49%), likely due to the immaturity of the neonates hospitalized in these centers.. We showed a still frequent use of corticosteroids in preterm infants in France but only after the fourth day of life to treat BPD and not as a prevention therapy. We also found a marginal use of DXM in accordance with both short-term and long-term adverse side effects, suggesting an unbalanced risk-benefit ratio even though it has a beneficial effect on respiratory status. Our findings indicate the need for national recommendations and trials to assess oral BMT treatment in premature neonates with BPD.

We investigated the role of eosinophils in the pathogenesis of bronchopulmonary dysplasia (BPD) in preterm infants.. Fifteen preterm infants with BPD were compared to 13 preterms with respiratory distress syndrome (RDS) and to 16 healthy preterms. We assessed total eosinophil and neutrophil counts in venous blood samples and the levels of the eosinophilic activity markers eosinophilic cationic protein (ECP) and the cellular surface antigen (CD9).. The eosinophil count was greater in BPD compared with RDS and healthy infants (1414 vs. 797 and 471 cells per microlitre, respectively, p = 0.03). ECP levels were elevated (34 vs. 12.8 and 9.8 microg/L, respectively, p = 0.002) and CD9 levels reduced (75 vs. 94 and 86 mean fluorescence intensity units, respectively, p = 0.01) in BPD compared with RDS and healthy infants, suggesting eosinophilic activation in BPD. These findings were not solely explained by differences between gestational age or birth weight of the different groups. ECP levels were positively correlated with the duration of oxygen supplementation in the BPD group. The eosinophil count fell promptly after steroid treatment was commenced in the BPD group.. The findings suggest that BPD is linked to eosinophil activation, which might contribute to the pathogenesis.

The aim of this pilot study was to determine the effect of early inhaled budesonide on clinical and inflammatory parameters in preterm infants ventilated for respiratory distress syndrome.. Neither the inflammatory process associated with respiratory distress syndrome nor the progression to bronchopulmonary dysplasia appeared to be altered by treatment with inhaled budesonide.

Local administration of steroids to the lungs in ventilated newborn infants can minimize the harmful side effects that occur with systemic administration. An efficient system of drug delivery that provides uniform distribution within the lungs is essential for the treatment of bronchopulmonary dysplasia. In this study we compare surfactant with 0.9% saline solution as vehicles for the direct instillation of a steroid (budesonide) into the lungs. Twenty-two anesthetized, ventilated rabbits received [3H]budesonide in either 0.9% saline or surfactant, administered through an endotracheal tube. Before drug administration, bronchial lavage was performed on half of the animals to serve as a model for surfactant deficiency. Lung samples were analyzed by both autoradiography (alveolar versus airway distribution) and liquid scintillation counting (central versus peripheral deposition). As expected, the delivered concentration of [3H]budesonide decreased as airway size decreased and branching increased. Significantly less [3H]budesonide was deposited in the alveolar spaces of all study groups compared with that deposited in the small and large airways (p < 0.05). However, both vehicles were equally efficient in delivering [3H]budesonide to the lungs. Although the alveolar and peripheral areas received less (4-11%) of the drug than the central tissue (14-28%), this was consistent among all the groups and was not affected by altered lung compliance. Therefore, either surfactant or saline could be used to efficiently and reliably deliver budesonide to the lungs at a level greater than that reported using nebulizers. Because normal saline is currently used for tracheal toilette, it is likely to be preferred considering the increased costs associated with surfactant.

The aim of the present study was to test the practicability of sequential cortisol determinations in saliva of low birth weight neonates and to evaluate the impact of systemic and inhaled glucocorticoid therapy on saliva concentrations of cortisol in preterm neonates with bronchopulmonary dysplasia (BPD). Salivary cortisol levels were measured by RIA in saliva samples from 10 full-term and 10 preterm healthy neonates and from 20 preterm neonates with BPD during systemic [dexamethasone (DEX); n = 10] or topical steroid therapy [budesonide (BUD); n = 10]. Saliva samples of each individual were collected on 3 consecutive days at 06.00, 12. 00, 18.00 and 24.00 h. Cortisol levels in saliva ranged from 0.8 to 60.6 nmol/l (median 6.5 nmol/l) in full-term neonates, from 0.6 to 52.1 nmol/l (median 5.5 nmol/l) in preterm neonates, from 0.4 to 14. 0 nmol/l (median 1.0 nmol/l) in preterm neonates treated with DEX and from 0.4 to 15.2 nmol/l (median 2.5 nmol/l) in preterm neonates treated with BUD. Autocorrelation analysis revealed a distinct endogenous cortisol rhythm in 2 of the 10 healthy full-term neonates and in 3 of the 10 healthy preterm neonates with a wavelength of 12-30 h. Salivary cortisol levels in preterm neonates treated with DEX or BUD were significantly lower than those measured in healthy preterm neonates. These results demonstrate that the measurement of salivary cortisol levels is a reliable and practicable way of assessing adrenal function in full-term and preterm neonates. This study also shows for the first time that some neonates display an endogenous cortisol rhythm which is not coupled to the exogenous day/night cycle. Furthermore, systemic and nebulized glucocorticoids suppress adrenal function in low-birth-weight neonates. After treatment these children should be closely monitored for potential adrenal insufficiency.
