Abramo, MD Hypothesis: For acute moderate to severe pediatric asthma exacerbations the use of NIPPV/BiPAP, in conjunction with current standard of care therapies, will lead to a more rapid improvement in patient ventilation, faster resolution of respiratory distress and result in improved ventilatory parameters, secondary outcomes and pediatric asthma scores. Study Design: Prospective, randomized controlled trial Study Duration: This study will be conducted over a 36 month period. Sample Size: 240 subjects Population: Children ages 2-17 years of age presenting to the ED with Acute asthma exacerbation and a Pediatric Asthma Score (PAS) ≥ 8. Synopsis: Eligible subjects will be randomized to either a control group or study groups. The study groups will be either a NIPPV/BiPAP group. The subjects in the study groups will continue to receive all standard of care therapies per the asthma severity protocols. All nebulized therapies will be given through the NIPPV circuit. Patients will be assessed by the pediatric asthma score (PAS), measured respiratory parameters, volumetric end tidal carbon dioxide monitoring and measured cardiac parameters. Objectives: A. Evaluate if the use of NIPPV/BiPAP in conjunction with traditional inhaled beta-agonists improves the outcome in pediatric patients with acute moderate to severe asthma in the acute setting. B. Describe the physiology of NIPPV/BiPAP by measuring cardiac parameters in children randomized to a NIPPV group. C. Monitor safety of NIPPV/BiPAP use for acute asthma exacerbations in children. Safety A.: The study must be IRB approved. B.: Appropriate consent and assent documents will be obtained prior to enrolling the subject in the study. C.: A clear safety plan including DSMB will be established to monitor for adverse events. D.: Confidentiality will be ensured for all subjects enrolled in the study.
The objective of this pilot study is to determine whether obesity and metabolic syndrome are in fact synergistic in relation to airway nitric oxide (NO) biology. To do so, the investigators want to determine how obesity and the metabolic syndrome relate to metabolism in bronchial airway epithelial cells and the nasal epithelium.
A randomized, multicenter, double-blind, placebo- controlled parallel-group study to determine the efficacy and safety of QAW039, compared with placebo, when added to standard-of-care (SoC) asthma therapy in adult and adolescent (≥ 12 years) patients with uncontrolled asthma with respect to change from baseline in forced expiratory volume in 1 second (FEV1) at the end of 12 weeks of treatment.
The purpose of this study is to verify the effects of continuous positive airway pressure (CPAP) on exercise capacity of children and adolescents with severe therapy-resistant asthma (STRA). A randomized, controlled, crossover clinical trial will be conducted. We expect the use of CPAP to increase exercise capacity in children and adolescents with STRA.
The environment during the prenatal period and in early life is a major contributor to the risk of developing childhood asthma. Birth cohort studies from single research centers have identified several factors that affect the risk for developing childhood asthma, including being exposed in early life to allergens, pollutants, viruses and bacteria, and psychosocial stress. Despite such advances, further progress in understanding the root causes of asthma have been hampered by the small size of previous studies, which makes it difficult to: 1) identify asthma risk factors with certainty, 2) know how environmental factors across the United States (U.S.) affect asthma, and 3) whether there are critical ages when pregnant mothers, infants and young children are particularly susceptible to these influences. Furthermore, different research groups tend to use different methods to study asthma, making it difficult to either compare or pool findings. One other challenge is that there are several types (i.e. phenotypes, endotypes) of childhood asthma, but these are poorly understood. To help overcome these challenges, investigators leading 12 asthma birth cohorts across the U.S. have established the Children's Respiratory Research Workgroup (CREW) consortium. CREW proposes to identify specific types of childhood asthma, develop an understanding of what early life environmental influences cause these different types of asthma and when, and identify targets for future efforts aimed at preventing childhood asthma.
Smoking occurs frequently in patients with asthma. Recent surveys on smoking prevalence report 21-26% current smokers in populations of patients with asthma. Detrimental effects of active smoking in asthma include worse asthma control, an impaired response to corticosteroids and accelerated lung function decline.
GSK3772847, an anti-interleukin (IL)33 receptor monoclonal antibody, is a novel treatment for asthma. This is a phase 2a study which aims to evaluate efficacy, safety, tolerability, pharmacokinetic (PK) and pharmacodynamic (PD) profiles of GSK3772847 in subjects with moderately severe asthma. The study will be conducted in 4 phases including screening, run-in phase, treatment phase and follow-up. In treatment phase, eligible subjects will be randomized to receive either GSK3772847 or placebo administered via intravenous (IV) route every 4 weeks in addition to open-label background therapy of fluticasone propionate/ salmeterol (FP/Sal) 500/50 micrograms (mcg) twice daily. During the treatment phase, the background therapy will be switched to FP 500 mcg for 2 weeks and the dose of FP will be reduced by approximately 50 percent at every 2 weeks until complete FP discontinuation. The total duration of study will be approximately 33 weeks and approximately 165 subjects with moderately severe asthma who are maintained on high-dose of inhaled corticosteroids/ Long-Acting Beta-2-Agonists (ICS/LABA) will be randomized.
In a randomized clinical trial (RCT) published in JAMA, the investigators have provided evidence that vitamin C supplementation (500 mg daily during pregnancy) ameliorates the effects of maternal smoking during pregnancy on offspring lung function and subsequent incidence of wheeze by 48% through 1 year of age. The investigators are currently completing a second RCT of vitamin C supplementation in pregnant smokers with more robust measures of pulmonary outcomes. The purpose of this ECHO application is to combine these 2 focused, interventional cohorts to allow critical longitudinal follow-up of respiratory outcomes in these children including the study of pulmonary function test (PFT) trajectories and incidence of recurrent wheeze/asthma from infancy through early adolescence in offspring of pregnant smokers randomized to vitamin C versus placebo.
The aim of this study is to compare the efficacy of a single dose of intramuscular dexamethasone versus 3 days of twice-daily oral prednisolone in the management of mild to moderate asthma exacerbations in children and test whether this single dose of intramuscular dexamethasone 0.6 mg/kg (max. 18 mg) is equal to prednisolone 1 mg/kg/day (max. 40 mg) in the treatment of exacerbations of asthma in children, as measured by the Pediatric Respiratory Assessment Measure (PRAM).
The investigators propose a home hospital model of care that substitutes for treatment in an acute care hospital. Limited studies of the home hospital model have demonstrated that a sizeable proportion of acute care can be delivered in the home with equal quality and safety, reduced cost, and improved patient experience.
