Active clinical trials for "Bronchiolitis"

The fraction of exhaled nitric oxide (feNO) in expired air is a reliable measure of airway inflammation. Some research experiments have demonstrated stimulation of nitric oxide production in respiratory epithelial cells infected with RSV. The principal aims are to determine if the fraction of exhaled nitric oxide (feNO) is elevated in hospitalized pediatric patients with viral lower respiratory illness and to determine if there is a difference in feNO level between RSV and non-RSV infection. NO may play a role in the association between RSV, airway reactivity, and airway inflammation. This is a prospective, pilot study that will noninvasively measure feNO in children 0-4 years of age admitted to Winthrop University Hospital, as well as controls (children in the same age range without respiratory conditions and who are well enough to perform the test). Hospitalized children will be tested for RSV (enzyme immunoassay (EIA) & DFA) and via direct fluorescent antigen technique (DFA) for influenza A & B, parainfluenza, human metapneumovirus and adenovirus. Method of feNO measurement will utilize the offline options for preschool children & infants appropriate for age as described in the 2005 Joint Statement of the American Thoracic Society & the European Respiratory Society when discussing tidal breathing techniques with uncontrolled flow rate Offline exhaled air can be collected via a mouthpiece or a face mask connected to a non-re-breathing valve that allows inspiration of NO-free air from an NO-inert reservoir to avoid contamination by ambient NO. Exhaled breath samples are collected into an NO-inert bag fitted with the expiratory port once a stable breathing pattern is present. The results of all 3 groups will be compared: control, RSV positive and RSV negative samples.

The primary goal of the study is to more firmly establish correlations between WheezeRate(Wz%) and other parameters used to assess wheezing and asthma including spirometry, provider's auscultation, and symptoms at the time of Wz% measurement.

The enrolled RSV-bronchiolitis patients will be randomized into two arms , the early HHHFNC group and the standard therapy group with rescue HHHFNC to study the efficacy of this treatment.

The aim of this study is to investigate if a standardized nutritional intervention with a protein and energy enriched milk could help overcome the catabolic state in children hospitalized with a bronchiolitis and thus creating a better nutritional state during hospitalization and at outpatient follow-up. The investigators also want to assess the clinical repercussion on the number of hospitalization days, the duration of oxygen support and the quality of life at ouptatient follow-up.

The aim of the study was to investigate the utility and safety of home management of home oxygen therapy in acute bronchiolitis. A matched case-control study, of one hundred and thirty five infants aged less than 12 months diagnosed bronchiolitis with hypoxia attending a pediatric community clinic will be randomly assigned to receive oxygen with or without standard nebulized therapy. Nebulized treatment with either 0.1% epinephrine diluted in bromhexine, or 3% hypertonic saline. Intermittent oxygen treatment will be administered 6 times daily for 7 days. Primary outcome measures will be emergency department visits/hospitalization secondary outcome measures will be changes in Bronchiolitis Caregiver Diary Score.

Bronchiolitis is an acute lower airway infection caused by a viral infection. It is a major cause of winter admissions to pediatric wards. Accepted therapies include oxygen support and IV fluids, whereas other supportive therapies such as inhalations are of questionable benefit. Moderate to severe cases are a source of distress to patient, parents and medical staff often necessitating Pediatric Intensive Care Unit admission. Heated Humidified High Flow Nasal Cannula (HHHFNC) therapy has been shown lately to improve the work of breathing, oxygen saturation, and CO2 pressure (PCO2) values as well as decrease PICU admissions and intubation rates. We planned a prospective and retrospective study in order to check the feasibility of using HHHFNC in a primary pediatric ward and its effect on clinical well being, respiratory status and PICU admission.

Nasal continuous positive airway pressure (nCPAP), widely used in neonatal intensive care is also more and more used in infants with severe acute bronchiolitis. There is no evidence that nCPAP improves outcome, but several studies showed that it reduces work of breathing (WOB), improves gas exchange and decreases intubation rate. High flow nasal prong (HFNP) therapy, also used in neonatal units, has recently been suggested for bronchiolitis management. This technique allows warmed and moist gas administration protecting nasal mucosa, and preventing variations of inspired gas FiO2. HFNP also creates a continuous positive pressure, reducing WOB, and seems much more comfortable and better tolerated by babies than nCPAP. There are no studies comparing both techniques for bronchiolitis management. The main objective of this study is to compare WOB with nCPAP and HFNP therapy in infants with severe bronchiolitis in pediatric intensive care unit. Secondary purpose is to compare efficacy and tolerance of both techniques. We propose to lead an open, single center, crossover randomized study. Each patient will receive the two treatments. Three consecutive periods will be studied: first one (minimum 2 hours), with the first technique CPAP or HFNP according to randomization (treatment 1); second period (2 hours) with the second technique (treatment 2); Third period (6 hours) with the second technique. The primary endpoint will be the comparison of WOB (estimated by the calculation of the transdiaphragmatic pressure-time product) at the end of the two firsts periods. Efficacy and tolerance of each technique will be evaluated and compared by compared measuring respiratory rate, heart rate, FiO2, SpO2, transcutaneous PCO2, modified Wood score, and EDIN score during the third period. Nine subjects by groups are required.

The fraction of exhaled nitric oxide (FeNO) in expired air is a reliable measure of airway inflammation and has been used as a marker in asthma and other respiratory illnesses such as primary ciliary dyskinesia, bronchopulmonary dysplasia (BPD), liver cirrhosis, chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF). Although, some exquisite bench research experiments have demonstrated stimulation of nitric oxide production in respiratory epithelial cells infected with RSV, there is a paucity of clinical data regarding levels of feNO in viral respiratory illness and specifically RSV. The investigators conducted a pilot study from the fall of 2007 until October of 2009, looking at FeNO levels in RSV infected patients and compared it to non-RSV viral infections. The investigators recruited a total of 28 RSV positive and 1 RSV negative subjects, as well as 4 control subjects. The investigators found FeNO values not statistically significant between the study group (the two-tailed p=0.09, considered not quite significant), but there was a trend of higher FeNO values in the non-RSV group when compared to the RSV group. A larger sample may detect a statistically significance between these 2 groups. Objectives: i. To determine if the fraction of exhaled nitric oxide (feNO) is elevated in hospitalized pediatric patients with viral lower respiratory illness when compared with normal subjects without respiratory symptoms. ii. To determine if there is a difference in feNO level between RSV and non-RSV infection in hospitalized pediatric patients with viral lower respiratory illness. Method of feNO measurement utilized the offline options for preschool children & infants appropriate for age as described in the 2005 Joint Statement of the American Thoracic Society & the European Respiratory Society when discussing tidal breathing techniques with uncontrolled flow rate. The investigators plan that our sample sizes for the RSV+ and control groups will be, by design, three times as large as the RSV- group. In order to achieve 80% power, the investigators will then require 45 control and 45 RSV+ patients, and 15 RSV- patients

The purpose of this study is to learn more about new noninvasive ways of detecting lung disease in US Military personnel and people who worked as contractors during military operations in Iraq and Afghanistan. This study is looking at conducting a type of breathing test called the lung clearance index (LCI) test which is being investigated as a potential noninvasive way to detect the type of lung disease that may be seen in symptomatic deployers retuning from Iraq and Afghanistan.

Pleuropulmonary echography remains an almost non-existent tool in routine pediatric practice. Our study is part of a desire to develop its use in pediatrics, in particular for the diagnosis of acute bacterial pneumonitis associated with acute bronchiolitis among infants.
