Airway Microbiome of Patients With Protracted Bacterial Bronchitis

This project aims to assess the relationship between the microbiome and virome composition, the immune responses, and the respiratory health of children with protracted bacterial bronchitis (PBB). In addition, we aim to evaluate how the standard treatment with azithromycin interacts with the components of the microbiome, virome and immune biomarkers.

Digital Physiotherapy for Pediatric Chronic Suppurative Lung Diseases

This is a prospective, single-center, two-arm (1:1), assessor-blinded, randomized controlled clinical trial that will be conducted in collaboration with the outpatient clinic of the third Pediatric Pulmonology Unit, "Attikon" University Hospital of Athens in Greece. The aim of the study is to investigate the effects of applying digital physiotherapy services in the management of specific clinical outcomes in children with chronic suppurative lung diseases, other than cystic fibrosis. The research question is whether airway clearance techniques and exercise training that are performed remotely using digital health services (DHSs) can improve functional and exercise capacity, as well as compliance with ACTs, compared to usual care. The intervention program includes airway clearance techniques (ACTs), as well as aerobic and strengthening exercises that can be implemented easily in an online setting at home with minimal equipment. The duration of the program will be 12 weeks, and the prescribed weekly regimen will consist of 50-minute remote sessions: two synchronous, supervised sessions conducted via the Vsee platform, and a minimum of one asynchronous, unsupervised session. Children will be encouraged to maintain daily adherence to the exercise protocol.

Biomarkers and Respiratory Omics as New CHildren Opportunities - Study of Clinical Outcomes and Predictivity Evaluation

The goal of this observational study is to improve the identification of biomarkers that predict disease progression and to assess the effectiveness of current therapies in children with asthma and protracted bacterial bronchitis. The main aim of the study is to evaluate the microbiome composition and diversity, cellular composition, and metabolomic profile. In addition, to assess their correlation on subsequent treatment and disease course in children with asthma, protracted bacterial bronchitis, and in those receiving inhaled glucocorticosteroids without a diagnosis of asthma. Participants will undergo fiberoptic bronchoscopy. During bronchoscopy, the performing physician will collect Bronchoalveolar lavage fluid samples for metagenomic and metabolomic analysis, as well as mucosal biopsies for histopathological evaluation.

Antibiotics, Microbiology and Immunology in Children With Chronic Wet Cough - the AMIC Study

The AMIC study is a double-blind, placebo-controlled, multicenter, nationwide, randomized controlled academic pharmaceutical trial. OVERALL PRIMARY OBJECTIVES: * To study the clinical efficacy of antibiotics in children with chronic wet cough (CWC). * To study if duration of treatment with antibiotics in children with CWC has impact on efficacy or time to relapse of symptoms. OVERALL SECONDARY OBJECTIVE: -To study respiratory pathogens and the diversity/composition of airway and gut microbiome in children with CWC compared to healthy controls, and changes in pathogens/microbiome after treatment with antibiotics. OVERALL TERTIARY OBJECTIVE: -To study the role of inflammation, immunology, and genetics in children with chronic wet cough and suspicion of PBB to increase the knowledge of pathophysiological mechanisms associated with PBB. The study will include two different RCTs AMIC 1 and AMIC 2: AMIC 1: Participants will be randomly assigned to 14 days amoxicillin-clavulanate syrup or placebo. AMIC 2: Participants will be randomly assigned 1:1 to receive either 14 or 28 days with amoxicillin-clavulanate syrup.
