Several epidemiological and cell-based data have demonstrated that respiratory virus infections differentially affect children, adults or the elderly populations. Perhaps, this difference has been put most notably into the spotlight by the current worldwide pandemic of SARS-CoV-2 with a large part of the deaths occurring in the elderly population whereas very few deaths amongst children have been recorded. According to some studies, this could be linked to a decreased transmission and/or viral load with SARS-CoV-2 in children compared to adults and elderly. What is less in the public eye is the observation that other major respiratory virus targeting the bronchial epithelium such as rhinovirus and adenovirus cause important clinical feature in children and have a much lower incidence in adults and the elderly populations, which is the opposite to the situation with SARS-CoV-2. Based on this remarkable discrepancy between respiratory viruses the investigators hypothesize that intrinsic age-controlled properties of the respiratory epithelium under resting physiological conditions determines virus susceptibility and virus propagation. Such hypothesis is supported by the literature and our own strong preliminary data. A highly complementing consortium composed of experts in lung physiology, pulmonary transcriptomic, respiratory viruses and ultrastructure analysis will address the question. The investigators will use three major respiratory pathogens (AdV, RV and SARS-CoV-2) to infect reconstituted fully functional respiratory epithelium obtained from children, adults and elderly and study parameters of virus infection and epithelial response. This project should highlight specific therapeutic targets against respiratory viruses with a high prevalence in children such as rhinovirus and adenoviruses to increase the therapeutic arsenal of clinician against those infections."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["CHILD"], "maximumAge"=>"17 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"Inclusion Criteria:\n\nFor pediatric patients requiring research-specific bronchial brushing:\n\n* Child under 18 years old,\n* Requiring bronchoscopy as part of routine care\n* Having informed and signed consent from the holders of parental authority\n\nFor pediatric patients whose bronchial brushing will be carried out as part of their care and for those whose surgical waste will be collected for research:\n\n* Child under 18 years old,\n* Requiring as part of routine care bronchoscopy and brushing or bronchial fibroscopy under general anesthesia or surgical resection/lobectomy\n* Having expressed their non-opposition to their child's participation in research\n\nFor adult patients:\n\n* Man or woman\n* Aged 18 or over\n* Requiring as part of the care, thoracic surgery such as lobectomy, pneumonectomy or lung transplantation in the Thoracic Surgery Department of Haut Lévêque du Chu Hospital in Bordeaux or inclusion in the TUBE study, described below.\n* having received an information note and not having objected to their participation in the research\n\nExclusion Criteria:\n\n* No affiliation or non-beneficiary of a social security system\n* During a period of relative exclusion compared to another protocol\n* Patient born before 36 weeks of amenorrhea\n* Patient with a documented history of pulmonary fibrosis, primary pulmonary hypertension, cystic fibrosis, pulmonary malformation or chronic viral infections (hepatitis, HIV).\n* Patient with any dental, nasopharyngeal or bronchial infection with fever (\\> 38°C) requiring systemic antibiotics in the previous 4 weeks"}, "identificationModule"=>{"nctId"=>"NCT06224062", "acronym"=>"VIRCHILLD", "briefTitle"=>"Virus and Bronchial Epithelium in Children and the Elderly", "organization"=>{"class"=>"OTHER", "fullName"=>"University Hospital, Bordeaux"}, "officialTitle"=>"Comparison of SARS-CoV-2, AdenoVIRus and Rhinovirus Infection of the Respiratory Epithelium in CHILdren vs. the eLDerly", "orgStudyIdInfo"=>{"id"=>"CHUBX 2021/43"}}, "armsInterventionsModule"=>{"armGroups"=>[{"type"=>"EXPERIMENTAL", "label"=>"children", "description"=>"reconstituted fully functional respiratory epithelium obtained from children (0 -18 years old)", "interventionNames"=>["Biological: SARS-CoV-2", "Biological: Adenovirus (AdV)", "Biological: Rhinovirus", "Biological: No Intervention"]}, {"type"=>"EXPERIMENTAL", "label"=>"adults", "description"=>"reconstituted fully functional respiratory epithelium obtained from adults (18 to 60 years old)", "interventionNames"=>["Biological: SARS-CoV-2", "Biological: Adenovirus (AdV)", "Biological: Rhinovirus", "Biological: No Intervention"]}, {"type"=>"EXPERIMENTAL", "label"=>"elderly", "description"=>"reconstituted fully functional respiratory epithelium obtained from adults (over 60 years old)", "interventionNames"=>["Biological: SARS-CoV-2", "Biological: Adenovirus (AdV)", "Biological: Rhinovirus", "Biological: No Intervention"]}], "interventions"=>[{"name"=>"SARS-CoV-2", "type"=>"BIOLOGICAL", "description"=>"Circulating strains of SARS-CoV-2 (including variants of concern) were already collected, cultured and purified.
