Filter by: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: 1. 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. 2. 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. In 2022/23 the study evolved from a prospective surveillance study into a genomic analysis study with sites collecting positive respiratory samples for RSV genomic review.
IRIS (Infection with RespIratory Syncytial Virus) is an observational, multi-center study enrolling infants with severe RSV infection and healthy controls. Inclusion criteria are age below two years and hospitalization due to RSV infection at three German sites. Exclusion criteria are premature birth, congenital or acquired bronchopulmonary or cardiac diseases, and immunodeficiency. Blood and respiratory specimens are collected upon admission, and RSV and other pathogens are analyzed by multiplex polymerase chain reaction (PCR). Further biomaterials including plasma, nasal lining fluid, blood cells, DNA, and RNA specimens are sampled in a dedicated biobank. Detailed information on demographic characteristics and medical history is recorded, as well as comprehensive clinical data including vital signs, medication, and interventions.
Hematopoietic stem cell transplant (HSCT) is an effective but toxic therapy, and lung injury affects as many as 25% of children receiving HSCT. Improved transplant techniques and major improvements in survival mean that HSCT is being more widely used, and more mismatched grafts are being used. Bronchiolitis obliterans (BO) is a major limitation of pediatric HSCT success as BO is commonly diagnosed late in children, when lung injury is irreversible, leading to long term morbidity or even death. Currently, there are major gaps in our knowledge regarding incidence, etiology and optimal treatment of BO following HSCT, and important diagnostic limitations specific to children. Diagnosis of BO is usually based on performance of pulmonary function tests, which is usually impossible in ill children under 10. Even older children who feel unwell or un-cooperative may be unable to produce interpretable data. These deficiencies in diagnosis mean that BO is commonly diagnosed late, meaning fibrosis has occurred and lesions are irreversible. The hypothesis for this interventional trial is that early treatment with standard Flovent/montelukast and steroids plus ruxolitinib will reverse lung injury and reduce the frequency of chronic pulmonary impairment or florid BO.
Bronchiolitis is a major public health problem and the leading cause of paediatric intensive care unit admission in infants. Hypophosphatemia is common in adult intensive care units and was associated with an increase of the duration of mechanical ventilation and the length of stay. Our hypothesis is that hypophosphatemia is common in bronchiolitis and could be a marker of severity.
Hospital admission for infant bronchiolitis is associated with an increased risk of recurrent wheezing and subsequent asthma in childhood. In the literature, 17 to 60% of children will develop repeated wheezing (infant asthma in France). This highly variable incidence could be linked in part to the fact that the definition of bronchiolitis varies between continents. In Europe the usual definition is an acute and contagious viral infection which affects the bronchioles (small bronchi) of infants accompanied by coughing, rapid breathing and wheezing. In research studies, bronchiolitis must be associated with wheezing and / or crackles on auscultation in Europe, and wheezing imperatively in the USA. The diagnosis of wheezing is difficult, and medical agreement on auscultatory respiratory abnormalities is poor. We thus have developed a wheezing diagnostic tool using artificial intelligence processing of respiratory sound recordings by smartphone (Bokov P, Comput Biol Med 2016, DOI: 10.1016/j.compbiomed.2016.01.002). In a second larger bicentric study that included only infants suspected of bronchiolitis, our approach has consisted in obtaining a recording by smartphone but also by electronic stethoscope in order to allow deferred listening of the sounds (WheezSmart study). The objective of these studies was to obtain a formal diagnosis of wheezing, the current project aims to assess the benefit of this diagnosis. The main objective of this cross-sectional study is to determine whether the formal presence (diagnosis of wheezing from a recording of pulmonary auscultation) is associated with the risk of childhood asthma (diagnosis of asthma at 6 years) regardless of the usual risk factors (atopic / allergic terrain, exposure to smoking, recurrence of symptoms). The secondary objectives are to determine whether the formal presence of wheezing on auscultation is a risk factor for subsequent repeated wheezing (diagnosis of infant asthma) and for initial disease severity (bronchiolitis) compared to SpO2 and admission of the child to hospital. The interest in differentiating between high and low frequency sibilants will be evaluated also.
This a research study to find out whether giving Continuous Positive Airway Pressure (CPAP) through a Helmet is the same or better than giving CPAP through a Facemask, Nasal Mask, or Nasal Prongs. CPAP can help kids with lung infections breathe easier. The machine delivers pressurized air, which may help people with lung infections breathe more easily. Doctors routinely use a Facemask, Nasal Mask or Nasal Prongs to give CPAP for kids with lung infections, but the researchers want to know whether using Helmet CPAP is the same or better.
Strengthening outpatient low respiratory tract infection surveillance to document the burden of Respiratory Syncytial Virus (RSV)
This study investigates a type of cell, called abnormal clonogenic epithelial cells, in patients with bronchiolitis obliterans syndrome who have had an donor stem cell transplant or a lung transplant. Learning more about clonogenic cells in these patients may help doctors to detect signs of bronchiolitis obliterans syndrome earlier in future patients.
This study aims to evaluate whether placing nasogastric tubes for gastric decompression improves respiratory distress for patients with bronchiolitis who are receiving oxygen via high-flow nasal cannula.
Many ambulatory networks are mainly based on diagnoses made by first-line physicians not specifically trained to join the network. Here we aim to set up a surveillance network on pediatric infectious diseases with an investment in teaching with specific trainings of participating pediatricians, increasing in use of point of care tests, and automated data extraction from the computers of the pediatricians.
