Active clinical trials for "Bronchiolitis"

Bronchiolitis is a very common winter disease that normally affects children less than one year of age. It is a common reason for parents and carers to bring their child to an Emergency Department (ED) and the frequent need for hospital admission means that paediatric units are at their capacity each winter. During the COVID19 pandemic the virus that causes bronchiolitis (Respiratory Syncytial Virus; RSV) disappeared meaning this winter there have been virtually no cases of bronchiolitis in the United Kingdom. This phenomenon has been observed in many other countries around the world. Evidence from Australia suggests as restrictions such as social distancing for COVID19 are relaxed bronchiolitis returns, even in the summer. At the release of lockdown the return has been so dramatic in some areas of Australia the summer time numbers are above a typical winter. There is also evidence it may affect older children up to 2 years of age. It is likely the Australian experience will be mirrored in the UK. The ability to track, anticipate and respond to a surge in bronchiolitis is important. There is a need to understand: the onset of RSV spread at the earliest opportunity. This is important as some children are at higher risk of hospitalisation, intensive care admission or death if they contract RSV; knowing when to passively immunise these children is a public health priority. whether the population at risk is a wider age range than normal and whether disease severity is greater as these will both effect service planning; There are currently no existing studies or surveillance systems fully able to address these questions. This study will use staff in Emergency Department to report, in real time, case of bronchiolitis that they see and record essential, but non-identifying, information about them.

This project aims to answer whether the use of a Neurally-Adjusted Ventilatory Assistance mode for non-invasive ventilation in pediatric patients with bronchiolitis results in improved comfort and reduced escalations in therapy (including intubation) when compared to using a standard mode of non-invasive ventilation. Neurally-Adjusted Ventilatory Assistance (NAVA) has been shown to result in greater synchrony then the standard mode of non-invasive ventilation. The study team hypothesizes that this improved synchrony can result in important clinical improvements when NAVA is used to treat children with bronchiolitis.

The goal of this clinical trial is to find out at which lower limit for saturation (amount of oxygen in the blood) we can best give extra oxygen to children that have been admitted for shortness of breath. We hope to accomplish a shorter period of illness for these children and that they can be discharged home earlier. Participants will receive supplemental oxygen if their blood oxygen levels are below 88% or below 92%. After admission, (parents of) participating children will fill out questionnaires. We will compare the two groups on their hospitalization duration and recovery. In other words, is it better to maintain a lower limit of 88% saturation or a lower limit of 92% in children admitted for shortness of breath?

The primary aim of this study is to determine prospectively the viral and C. pneumoniae infection prevalence and outcomes of infections in lung transplant recipients. The study will also determine the correlation of C. pneumoniae infection with the development of obliterans in lung transplant recipients.

This observational trial studies whether respiratory viruses are the cause of lung disease (bronchiolitis obliterans syndrome [BOS] or graft-versus-host disease of the lung) and changes in lung function in patients who have received a donor stem cell transplant. Patients with chronic graft-versus-host disease (cGVHD) are at higher risk of developing BOS. Studies have also shown that patients who had a respiratory viral illness early after their transplant are at higher risk of developing lung problems later on. Patients who are at risk and who already have BOS might benefit from being monitored more closely. Spirometry is a way of assessing a patient's lung function and is often used to diagnose lung disease. Spirometry measured at home with a simple handheld device may reduce the burden of performing pulmonary function testing at a facility and potentially help patients get their lung disease diagnosed and treated sooner.

Bronchiolitis is an acute viral infection of the lower respiratory tract. It is most commonly caused by respiratory syncytial virus (RSV). Only supportive therapy, including suctioning nasal secretions, water-electrolyte balance maintenance, and oxygen supplementation when needed, is recommended. The inhalation of 3% hypertonic saline is not recommended in bronchiolitis management. However, a recently published meta-analysis revealed that the inhalation of hypertonic saline can reduce the risk of hospitalisation for outpatients with bronchiolitis, while resulting in a shorter length of hospital stay and reduced severity of respiratory distress for inpatients, although the evidence is of low certainty. The aim of the study is to assess the efficacy of nebulised hypertonic saline for the treatment of children hospitalised with bronchiolitis.

Respiratory tract infections caused by respiratory syncytial virus (RSV) are a worldwide burden and represent a major public health issue. In France, bronchiolitis is responsible for around 100,000 emergency room visits and 50,000 hospital admissions every year; 75% of infants hospitalised for RSV bronchiolitis are healthy full-term children. Recent discoveries concerning the specific viral epitopes of RSV have made it possible to move from an empirical approach to a targeted preventive or curative approach (monoclonal antibodies, vaccines, anti-viral drugs). Nirsevimab is a monoclonal antibody against RSV with enhanced neutralising activity and a prolonged half-life. A randomised, placebo-controlled phase III trial demonstrated the effectiveness of nirsevimab in reducing lower respiratory tract infections caused by RSV requiring medical management in healthy premature and term infants, with a favourable safety profile. The US Food and Drug Administration (FDA) approved the first RSV vaccine on May 3, 2023, and the second was approved on May 31, 2023. Nirsevimab was approved by the European Medicines Agency (EMA) on November 4, 2022.

In this study, we will study 129Xe-MRI and LCI as tools for diagnosis of BOS in pediatric patients who have received Hematopoietic Stem Cell Transplantation (HSCT) and have been identified as eligible for this study. Participants will be required to have vital signs collected, complete breathing tests and complete an MRI. The MRI will require participants to perform breath holds in the MRI scanner with xenon gas while being coached by a research assistant.

The Lung Clearance Index, measured by multiple breath washout, is a measure of lung function that is considered a research tool in Canada as the device used to measure it is not approved by Health Canada. The study will assess lung function in patients undergoing routine lung function testing for clinical indications (Cystic Fibrosis and Other Respiratory Diseases). In addition, healthy controls of different ages will be asked to perform this lung function test to gain reference data that can be used to interpret LCI in patients with lung disease.

The goal of this research study is to test the efficacy of a novel immunosuppressive agent, belumosudil, in allogeneic hematopoietic stem cell transplant (HSCT) recipients who have been newly diagnosed or have developing (early stage) bronchiolitis obliterans syndrome (BOS). The name of the study drugs involved in this study are: Belumosudil (an immunotherapy) Fluticasone (an intranasal corticosteroid) Azithromycin (an antibiotic) Montelukast (a leukotriene receptor antagonist) Prednisone (a corticosteroid)
