Filter by:Single centre, double-blind, placebo controlled, adaptive design, cross-over trial. The primary objective is to assess the additive effects of using combined intranasal fluticasone propionate plus azelastine nasal spray on airway hyperresponsiveness. This is in patients with persistent asthma and allergic rhinitis, receiving inhaled steroid.
Chronic respiratory diseases (CRDs) affect the airways and other structures of the lungs and thereby lead to ventilation inhomogeneity. The most common CRDs in children are asthma, bronchiectasis and cystic fibrosis (CF). All three are obstructive diseases. However, while asthma is mostly characterized by obstruction due to bronchoconstriction of the airways, obstruction in bronchiectasis and CF originates primarily from mucus retention due to abnormal airway clearance mechanisms. The Nitrogen Multiple Breath Washout test (N2-MBW-test) is a robust and sensitive detector of early pulmonary changes and ventilation inhomogeneity. The minimal cooperation which is required for this test makes it very convenient for use in any age category. Research on LCI described it as a reliable indicator of obstructive lung disease in pediatric CF patients as from 6 years of age. Whether LCI is a reliable parameter for early lung disease in asthma children is less clearly demonstrated. No data were found on LCI calculated from the N2-MBW-test in children with bronchiectasis.
This is an exploratory study with the following primary objectives: 1) to establish that PET/CT of the lung can reliably distinguish healthy, non-asthmatic participants from participants with severe asthma and an eosinophilic phenotype and 2) to examine the utility of PET/CT for demonstrating that reslizumab produces a reduction in lung inflammation in participants with severe asthma and an eosinophilic phenotype .
The intrinsic asthma (atopic or not) is a particular phenotype marked by an early later symptoms, increased severity, sensitivity associated with nonsteroidal anti-inflammatory drugs (NSAIDs), a sinonasal polyposis and eosinophilia. Unlike allergic asthma, this form does not today demonstrated its genetic character. However, the existence of familial forms of asthma in this region Pays de La Loire led us to hypothesize the existence of genetic variations can explain some familial forms of non-atopic asthma. Corresponding genes may be relevant to understanding the pathophysiological pathways involved in the more common sporadic forms. The investigators propose a study combining genetic linkage analysis and complete sequencing exomes to identify one or more genetic abnormalities associated with non-atopic asthma. The clinical stage essential for mutation identification is to identify and recruit large families with members affected by non-atopic asthma and ensure accurate phenotyping of all individuals recruited over several generations. The aim of this study is to create a cohort of families who have more members within them non-atopic asthma. A high genetic combined exome sequencing throughput analysis in a family linkage study will then reveal the presence or absence of genetic variations associated with intrinsic asthma.
A 52-Week, Open-Label, Multicentre Study to Evaluate the Safety of Tralokinumab in Japanese Adults and Adolescents with Asthma Inadequately Controlled on Inhaled Corticosteroid plus Long-Acting β2-Agonist
Prospective, multicenter, single-arm (non-randomized) study of Targeted Lung Denervation (TLD) Therapy in subjects with severe asthma.
This is an observational study which aims to evaluate the possibility of using data from a capnography device to assess obstructive airway severity in both Chronic Obstructive Pulmonary Disease (COPD) and Asthma patients.
Asthma is the most common chronic disease of children. A short (3-5 day) course of a short-acting steroid such as Prednisone or Prednisolone has long been the standard of care for asthma exacerbation. Dexamethasone efficacy in asthma exacerbation has been studied in the outpatient setting and was found to be as effective as Prednisone. Dexamethasone has the advantage of shorter course, more compliance, and more tolerable. This has led many emergency departments to provide a 1-2 dose course of Dexamethasone on discharge. Thus, many inpatients have received a first dose of Dexamethasone prior to reaching the inpatient unit, leading to confusion about the best plan for these patients. Many hospitalist pediatricians continue to give a 5-day total course with Prednisone, but some patients have begun to receive a second dose of Dexamethasone 24 hours after the first dose. To our knowledge, no studies have been done to compare the efficacy of these two protocols in pediatric patients requiring hospitalization. The hypothesis is that a second dose of Dexamethasone is as effective as four additional days of Prednisone in hospitalized children with asthma exacerbation. This is an open label, randomized control study comparing these treatments in children age 2-18 hospitalized with asthma exacerbation who have received a first dose of Dexamethasone.
Eviction methods for dust mite allergy have been evaluated in asthma control in a recent Cochrane meta-analysis. None have shown efficacy on asthma control and there are not recommended. The purpose is to evaluate the efficacy of a new commercialized system (Acar'Up) to decrease dust mite load and to assess its impact on the possibility to perform inhaled corticosteroids step down in stable asthmatics.
This study will determine whether vitamin D3 prevents severe asthma attacks in children who have a serum vitamin D (25(OH)D) level <30 ng/ml and who are being treated with inhaled corticosteroids for asthma. Half the participants will receive vitamin D3 at a dose of 4,000 IU/day, and the other half will receive placebo.
