Filter by:Background: Asthma and obesity are public health crises that have concurrently risen over the past decades, affecting millions of children in the United States and disproportionately affecting low-income minority children in urban areas. The same children at highest risk for asthma and obesity also have greater exposure to indoor and outdoor pollution. Emerging evidence suggests that obesity may confer increased susceptibility to health effects of air pollution. Methods: Aiming to provide causal-level evidence of these observational findings, we propose a home intervention study to 1) test whether targeted reductions of indoor Particulate Matter (PM) concentrations improve the respiratory health of overweight inner-city children with asthma more than that of lean inner-city children with asthma and 2) investigate mediators of susceptibility to indoor PM among overweight versus lean children with asthma. We will accomplish these aims using a 1:1 randomized controlled trial of 200 children with persistent asthma (half normal weight, half overweight) living in Baltimore City. Participants will be randomized to receive either two active air purifiers containing high-efficiency particulate air (HEPA) filters or two sham air purifiers with their filters removed. Implications: If the aforementioned observational findings are confirmed, implications will be directly relevant to the over 170 million children around the world now estimated to be overweight or obese.
FeNO measurements provide the physician with means of evaluating an asthma patient's response to anti-inflammatory therapy, as an adjunct to the established clinical and laboratory assessments in asthma. Interpretation of FeNO profiles is based on the nitric oxide plateau. To achieve plateau, the duration of exhalation must be sufficient (at least 4 seconds for children <12 years and > 6 seconds for children > 12 years (ATS/ERS, 2005). Measurement of FeNO using the 6-sec mode may provide a viable alternative in children as young as age 4 years who may have difficulty maintaining exhalation for a full 10 seconds.
The PRE-AR project is a longitudinal observational study. The primary objective is the assessment of lung function parameters in late preterm preschool children.
This trial is a randomized, double-blind, placebo controlled trial designed to test whether two years treatment of preschool children aged 2-3 years of age at high risk for asthma with omalizumab (anti-IgE) for two years will prevent the progression to childhood asthma, as reflected by a reduction in the prevalence of active asthma in the Final 12 months during 2 year observation period off study drug.
This research study is being done to learn more about severe asthma by comparing people with severe asthma to those with milder forms of asthma and people without asthma, at baseline and over time. Individuals are being asked to join a research study to help understand the differences in the lungs and blood of participants with severe asthma compared to those with milder asthma and healthy individuals, as well as differences in overall health. Investigators also want to determine whether these differences predict asthma-related and biologic outcomes over 1 year of follow up.
The differential diagnosis of asthma and COPD is sometimes difficult. Recently, an overlap syndrome has been defined based on the concurrence of asthma and COPD characteristics. These characteristics are based on expert opinions and have never been investigated nor validated prospectively. The investigators assume that the management strategy, the symptom burden and disease progression will differ between asthma, COPD and ACOS. Therefore, the study wants to establish baseline criteria for an appropriate disease definition and evaluate the potential impact on treatment and symptom control.
The primary objective is of the PreventADALL study is to test if primary prevention of allergic diseases is possible by simple and low cost strategies, and secondary to asses the impact of xenobiotic exposure and microbiota in and on the body and the environment on allergic disease development. The secondary objective is an exploratory focus to investigate early life risk factors for development of non-communicable diseases, including asthma and allergic diseases as well as for diseases that may share common risk factors, including cardiovascular disease, obesity and diabetes. Design: A multi-national population-based prospective birth cohort with a factorial designed randomized controlled intervention trial of two clinical interventions; skin care 0-9 months and early food introduction by 3-4 months, thereafter observation only. Recruitment in three cities (Oslo, Ostfold and Stockholm) of approximately 2500 mother-child pairs is done in two steps; first pregnant women are recruited and enrolled at the 18-weeks ultrasound investigation (n=approximately 2700) and thereafter their new-born babies are included. Randomization into four groups is done by the postal code or "township" to ensure all four intervention-groups within each "township". Visits for biological and environmental sampling, observations and investigations will be at the relevant pediatric departments (at 3-6-12-24-36 months of age) and through childhood into adulthood thereafter, provided sufficient funding.
A Randomized, Double-Blind, Chronic Dosing (14 days), 5-Period, 7-Treatment, Placebo-Controlled, Incomplete Block, Cross-Over, Multi-center, Dose-ranging Study to Assess the Efficacy and Safety of Glycopyrronium MDI (PT001) Relative to Placebo MDI and Open-Label Serevent Diskus in Adult Subjects With Intermittent Asthma or Mild to Moderate Persistent Asthma
The first-in-man study are designed as below to assess safety, tolerability, and preliminary pharmacokinetics of ZL-2102. - Double-blind randomized, placebo-controlled ascending single oral doses (Part 1, ZL-2102-SAD); - Open-label, randomized, 2-sequence, 2-period, 2-treatment crossover (Part 2, ZL-2102-FED); - Double-blind randomized, placebo-controlled, ascending repeated oral doses for 14 days (Part 3, ZL-2102-MAD). A total of 104 subjects will be enrolled.
The purpose of this study is to determine whether extra fine formoterol/beclomethasona are more effective in the treatment of asthmatic crisis when added to conventional treatment compared with conventional treatment alone.
