Active clinical trials for "Bronchiolitis"

The goal of this clinical trial is to determine whether it is possible to identify, enroll, and deliver the study intervention (the corticosteroid dexamethasone) in hospitalized infants with bronchiolitis. Participants in this study will be given two doses of dexamethasone within 72 hours of enrollment, followed by 30 days of safety monitoring. Results of this feasibility pilot study may be used to inform the design of a future randomized controlled trial, whose results in turn could induce a paradigm shift in acute management of bronchiolitis.

The purpose of this prospective study is to evaluate the efficacy of the ResAppDx software application in the diagnosis of childhood acute respiratory disease, including pneumonia, bronchiolitis, asthma/reactive airways disease, croup, lower respiratory tract disease (LRTD), viral lower respiratory tract infection (vLRTI), and upper respiratory tract disease (URTD).

Infant bronchiolitis is a frequent pathology that is the cause of a very large number of medical outpatient and physiotherapy treatments in France. Many international studies and recommendations have invalidated any drug treatment during its management during the first episode. In France, the consensus conference promoted by the National Agency for Accreditation and Health Evaluation (ANAES) in September 2000 was in the same vein. Regarding the respiratory physiotherapy component, posture drainage, vibration and percussion are not considered effective. ANAES recommended the use of respiratory physiotherapy with passive exhalation techniques. This is a method of care that has developed mainly in French-speaking countries, making it difficult to compare with the habits of Anglo-Saxon countries, which, more generally, do not prescribe it. In France, the level of evidence of its effectiveness is considered low (grade C). To date, the vast majority of studies have focused exclusively on a population of infants hospitalized for severe bronchiolitis. For this type of population, the value of such treatment to shorten the healing time has not been demonstrated. So much so that the ANAES, in its time, recommended that studies be carried out "on an outpatient basis" to assess their degree. In this respect, several recent studies have provided new data. Despite the reservations inherent in their methodologies and/or staff, they raise the question of the interest of the respiratory physiotherapy on an outpatient basis. In terms of professional practice, the American recommendations state that clinicians should educate family members about evidence-based diagnosis, treatment and prevention in bronchiolitis. Finally, an opinion survey concludes that holders of parental authority are seeking information on bronchiolitis and that approximately 90% have read the brochure given out of the maternity ward explaining the modes of transmission, manifestations, care and hygiene measures in the event of bronchiolitis. Pending new French recommendations, it seems legitimate to evaluate the level of perception of the effect of pediatric respiratory physiotherapy with increase in expiratory flow (IEF) in urban practice on the respiratory comfort of infants directly with families confronted with this pathology.

Acute bronchiolitis is a frequent respiratory viral infection of infants, responsible for 460,000 new cases per year in France. Over the years, the number of hospitalizations during the epidemic season appears to be increasing. Bronchiolitis epidemics lead to recurrent hospital disruption. The current trend towards a reduction of hospital beds is exacerbating the pressure on bronchiolitis epidemics on healthcare systems. In this context, the pediatric departments of Montpellier University Hospital, France, designed in 2014 a common organizational infrastructure pediatric plan (OIPP) to to adapt to these multiple constraints while respecting the quality of care. This plan includes a referral flowchart for hospitalized children, an increase in medical and paramedical staff and a restructuring of the pediatric units, with a specific stratification into 4 levels of care. The study aims to assess the impact of our OIPP on the overall length of stay for children hospitalized for bronchiolitis. The investigator also intend to measure the impact of the OIPP on the length of stay within each unit, the number of transfers from one unit to the other and the number of readmissions within 30 days after hospital discharge. The cost of the implementation of the OIPP in the structure will be analyzed.

The purpose of the study was to test the null hypothesis that there is no difference between nasal continuous positive airway pressure / nasal positive pressure ventilation (NCPAP/NPPV) and high flow nasal cannula (HFNC) devices when applied as a first non-invasive respiratory support mode for severe bronchiolitis

Bronchiolitis is a significant cause of morbidity and hospitalization in children, accounting for approximately 125,000 hospitalizations per year in the U.S. Recently, genetic variations of the β2-adrenergic receptor (β2-AR) have been shown to influence response to β2-AR agonist therapy in children with asthma. We suspect that genetic variations of the β2-AR also affect response to β2-AR agonist therapy in children with bronchiolitis.

The purpose of this study is to collect information about what happens to certain chemicals produced in the body called hormones during respiratory infections such as bronchiolitis. Bronchiolitis is an infection of small airways in the lungs caused by a virus. This infection, which causes swelling and injury in the lungs, is commonly seen in infants and children less than 2 years of age.

The investigators have obtained compelling evidence that the development of anti-human leukocyte antigen (anti-HLA) antibodies against mismatched donor antigens significantly correlates with the development of bronchiolitis obliterans (BOS). Further, these anti-HLA antibodies are developed at least 15 months prior to any clinical evidence of BOS. This lag period between the development of anti-HLA antibodies and the onset of BOS gives us an opportunity to intervene to delay and/or prevent the development of BOS.

Recently, an epidemic of pulmonary disease has been recognized among workers in a popcorn factory in Jasper, Missouri. The exposure agent has not yet been identified, but suspects include butter flavoring and the powdered salt used in the mixing room. This disease resembles "Bronchiolitis Obliterans Syndrome", an illness that makes it difficult to breathe. Of the 117 workers studied, one year later, 25 subjects whom were working in the mixing room or in the microwave packaging area have had decreases in lung function seven times the norm for their age. Industrial hygiene experts revealed that dust concentrations of salt and other flavorings were much higher in the mixing room compared to the office and outdoor work areas. Recently, rats were exposed to vapors created by heating the butter flavor compound obtained from this plant. Six-hour exposure to vapors at very high concentration resulted in significant damage to the breathing apparatus. Thus, there is clinical, epidemiological, and animal toxicity data that appears to implicate some constituent present during the mixing of the butter flavoring, salt, and oil causing a form of obstructive airway disease that has been rapidly progressive in a number of workers. It is not clear what the pathophysiologic nature of this entity is, though it resembles Bronchiolitis Obliterans Syndrome. It is not known what the long term consequence of this will be on the active workers, nor is it clear whether preventive measures taken to reduce exposures in the mixing room and elsewhere in the plant are going to be effective.

The purpose of this study is to investigate the effect of cohort isolation of RS(respiratory syncytial virus)-positive bronchiolitis versus RS-negative bronchiolitis on prevention of co-infection and clinical disease severity. Furthermore the investigators want to elucidate general epidemiological data on bronchiolitis concerning viral causes and the associated clinical severity. The investigators want to conduct a prospective cohort study, comparing incidence of co-infection and clinical severity, in two cohort: one with isolation of RS positive bronchiolitis as a separate cohort within bronchiolitis and one without isolation (all children with RS-negative bronchiolitis are nursed together independent of viral agent)
