The investigators here compare lung function parameters (RV, RV/TLC and FEF75) with the results of the Lung Clearance index (LCI) . Further this study evaluates bronchial inflammatory markers in 20 patients with bronchiolitis obliterans at the age of 6 to 28 years compared with an age- and sex-matched control group. The investigators will perform a pulmonary function test (body plethysmography with DLCO) and compare the results with the LCI. Further we will measure the fraction of exhaled nitric oxide (FeNO) and draw a blood sample to determine the level of systemic inflammation. Finally induced sputum is collected and a cell count is performed, and cells and supernatants are analyzed for inflammatory markers. This study will set baseline markers for future interventional studies.
The purpose of this study is to compare the immediate effects of retrograde rhinopharyngeal clearance with nasopharyngeal aspiration in children admitted with acute viral bronchiolitis. The investigators selected children, up to 12 months old, admitted for acute viral bronchiolitis. Patients were divided in aspiration group (AG), submitted to nasopharyngeal aspiration, and clearance group (CG), submitted to retrograde rhinopharyngeal clearance with physiological solution (0.9%) instillation (RRC) technique. In both groups children were evaluated three times in the same day in order to verify cardiorespiratory parameters, clinical score of respiratory dysfunction and adverse effects.
The objective of this study is to evaluate the clinical response of children diagnosed with acute bronchiolitis, relative to a chest physiotherapy protocol. Comparing this treatment with standard care of the nursing staff and auxiliaries of infants patients aged 1 month to 2 years.
The main long-term complication of lung transplantation is chronic lung allograft dysfunction (CLAD). Bronchiolitis obliterans syndrome (BOS) is the most frequent presentation of CLAD. BOS leads to a progressive loss of lung allograft function, with recurrence of dyspnea and airflow limitation. In some advanced cases, patients need a lung re transplantation. The mechanisms of BOS are not completely elucidated, and there are no early markers or specific treatment available for this condition. Microparticles (MPs) are submicron plasma membrane fragments released into the vascular compartment or the pericellular space in response to cell activation, injury or apoptosis. Broncho alveolar and circulating MPs may reflect cellular insults of the lung allografts. Therefore, MPs could be viewed either as biomarkers or as effectors of the chronic inflammatory or procoagulant processes leading to bronchiolitis obliterans syndrome. The investigators plan to include 60 patients before lung transplantation at our centre in Strasbourg (France). Follow-up will be requested at the base of usual care (spirometry, blood sampling, bronchoscopy with broncho-alveolar lavage [BAL]). The investigators will measure at one month, one, two and three year post transplantation, the total concentration of MPs in plasma and BAL and characterize their phenotype. The investigators objective is to demonstrate correlation between total MPs concentration in broncho-alveolar lavage fluid (BALF) and the occurrence of bronchiolitis obliterans syndrome at three years post lung transplantation.
There is a growing body of literature suggesting that monoclonal antibody could be efficacious in infants with RSV-bronchiolitis, well tolerated with no or clinically insignificant adverse effects. "The investigators hypothesize that a single dose of iv palivizumab 15 mg/kg in diagnosed infants <3 months old with RSV bronchiolitis will result in fewer infants with readmissions to infirmary/observation or hospital for relapse during 3 weeks of follow-up after discharge".
The objective of this study is to detect Bronchiolitis Obliterans Syndrome (BOS) in an early stage using the outcome parameters generated by Functional Respiratory Imaging (FRI). Robust and automated segmentation algorithms will be developed for these parameters, focusing on quantitative computed tomography (CT) image analyses to provide the physician a more sensitive diagnostics tool. The evolution of BOS over time will be monitored using nmon-rigid image registration methods.
This trial objective is to assess whether doubling the daily intake of vitamin D improves serum vitamin D levels and serves as primary prevention of respiratory infections and asthma in premature infants. This is a prospective randomized (1:1) double-blinded trial. The study population will be randomized into two groups (1:1): - Intervention Group - 800 IU of Vitamin D once daily - Control Group - 400 IU of Vitamin D once daily Patients will be followed up for one year after randomization for serum Vitamin D levels and respiratory morbidity.
Humidified High Flow Nasal Cannula (HHFNC) is a new modality of respiratory support for children with respiratory failure. Despite its extensive use in pediatric and adult population, the exact mechanism of work of HHFNC is not fully explained.The objective of the investigators' research project is to determine the relationship between the amount of airway pressure that can be delivered at specific flow levels of HHFNC. This information will allow the investigators to use HHFNC in a much more informed and safe manner.
