Active clinical trials for "Bronchiolitis"

Serum KL-6 protein has been described as a biomarker of epithelial lung injury in Respiratory Syncytial Virus bronchiolitis. The investigators can imagine that epithelial injury intensity has consequences on immediate and later respiratory prognosis. Furthermore, this prognosis seems to be different according to the respiratory causative virus. The investigators propose to study, during an epidemic season, the correlation between KL-6 levels and clinical severity, and the type of viral infection.

Epidemics and infectious diseases in general, punctuate much of the activity of an emergency service. The impact of winter infections is particularly important to vulnerable populations such as infant during bronchiolitis epidemics and the elderly during seasonal influenza. Each year, these epidemic phenomena lead to disorganization of emergency services and healthcare teams by lack of anticipation and organizational measures in particular to manage the approval of emergency services for the most vulnerable populations requiring hospitalization. For 2 years, the pediatric emergency department of St Etienne University Hospital has a decision support tool for the periods of winter epidemics. Through a retrospective analysis of Passages of Emergency summary, this tool provides an estimate of infants with bronchiolitis flow day to day, and the availability in real time of an abnormally high flow of patients to pediatric emergencies. These data can help to affirm that the epidemic begins in this hospital.

Chronic organ dysfunction after lung transplantation (BOS) is the most common cause of death in long-term survivors after lung transplantation and refractory to most interventions. Early markers will be established in this project study to overcome the problem of disease recognition when impairment of graft function is already taken place. Long-term longitudinal monitoring in stable recipients of innovative markers of airway inflammation and ventilation and new imaging techniques will define different entities of chronic organ dysfunction after LTx. A database and specimen service unit for further projects will be created. Hypothesis: This project will reveal new markers and imaging tools in recipients who develop BOS after lung transplantation. These tools will allow earlier diagnosis and more accurate monitoring of the disease process. Different patterns of the disease will be characterized.

The purpose of this study is to determine Fractional exhaled Nitric-Oxide (FeNO)levels and blood cytokines during acute bronchiolitis, and to seek for correlation between these markers and future development of asthma.

There is a large and growing body of animal evidence demonstrating neuroapoptosis and neurodevelopmental abnormalities after exposure to anesthetic agents. This has prompted an FDA warning concerning use of anesthetics and sedatives in children under 3 years of age. There has been very little investigation of the neurodevelopment effects of prolonged sedation in previously healthy infants in Paediatric Intensive Care. This feasibility study will recruit previously healthy infants who required respiratory support with or without sedation at up to 1 year of age and assess neurodevelopmental outcomes at 6 years of age.

Reducing tobacco consumption is a major public health objective, with the prevalence of active smoking estimated in 2017 at 26.9% of the French population aged 18 to 25. The negative impact of passive smoking on children's health and development has been demonstrated by numerous studies, especially with regard to respiratory pathologies. Parental smoking is also a risk factor for active smoking in adolescence and adulthood (with an odds ratio of 1.72 if at least one of the two parents is a smoker). It has been shown that intervention with parents can reduce the number of children exposed to passive parental smoking by about 5%.

Acute viral bronchiolitis is the leading cause of community-acquired acute respiratory failure in developed countries (20 000 to 30 000 hospitalizations each year in France). Between 5% and 22% of these children are hospitalized in a critical care unit to benefit from a respiratory support. Non-invasive ventilation, in particular the nasal Continuous Positive Airway Pressure (nCPAP), reduces the work of breathing in children with bronchiolitis and is associated with decreased morbidity and hospitalization costs compared with invasive ventilation. Nowadays, this technique is considered as the gold standard in the pediatric intensive care units (PICU) in France. High Flow Nasal Cannula (HFNC) has been proposed as an alternative to the nCPAP because of its better tolerance and simplicity of implementation. However, the proportion of failure remains high (35 to 50%), providing only a partial response to the care of these children, especially prior to the PICU. In a physiological study (NCT02602678, article published), it has been demonstrated that prone position (PP) decrease, by almost 50%, the respiratory work of breathing and improve the respiratory mechanics in infants hospitalized in intensive care units for bronchiolitis. Investigators hypothesize that prone position, during High Flow Nasal Cannula (HFNC), would significantly reduce the use of non-invasive ventilation (nCPAP and others) or invasive ventilation, as compared to supine position during HFNC, in infants with moderate to severe viral bronchiolitis.

The REspiratory Syncytial virus Consortium in EUrope (RESCEU) is an Innovative Medicine Initiative (IMI) effort funded by the EU under the H2020 framework to define and understand the burden of disease caused by human respiratory syncytial virus (RSV) infection. RSV causes severe disease in individuals at the extremes of the age spectrum and in high risk groups. It was estimated that RSV was associated with 34 million cases of acute respiratory tract infection (ARTI), 3.4 million ARTI hospitalizations and 55,000 to 199,000 deaths in children <5 years in 2005 worldwide. These estimates were based on limited data and there is a substantial gap in knowledge on morbidity and associated healthcare and social costs in Europe. New vaccines and therapeutics against RSV are in development and will soon be available on the European market. RESCEU will deliver knowledge of the incidence and burden of disease RSV in young children and older adults in Europe, which is essential for stakeholders (governments, etc) to take decisions about prophylaxis and treatment. Objective: To determine the burden of disease due to RSV in young children. Study design: Prospective epidemiological, observational, multi-country, multicenter cohort study. Study population: Birth cohort of healthy infants (follow-up from birth until the age of 3 years maximum): Passive birth cohort (n=9,000). Active birth cohort (n=1,000). Main study parameters/endpoints: The primary endpoint of the study is the incidence of RSV infection-associated ARTI, RSV associated medically attended (MA) ARTI (active birth cohort) and RSV related hospitalization (passive birth cohort) in infants (< 1 year) during 3 RSV seasons. In addition, a major secondary endpoint is RSV attributable burden of wheezing.

This study aims to determine whether or not early spirometric detection and management of obstructive lung disease with combined fluticasone/azithromycin/montelukast therapy (FAM) can attenuate declining lung function, prevent the development of bronchiolitis obliterans, and improve patient outcomes following hematopoietic stem cell transplant.

The researchers are investigating a novel technique, the multi breath nitrogen washout technique, to measure airway changes in various respiratory diseases.
