Advancing Diagnosis and Treatment of Pediatric Asthma

Asthma is one of the most common chronic diseases in children, and treatment success often depends on proper inhaler use and consistent medication adherence. Exposure to allergens and pollutants can also impact treatment response and asthma control. Moreover, there is a growing need for non-invasive biomarkers to support better diagnosis and personalized care. The goal of this clinical trial is to investigate if a new digital inhaler can improve inhalation technique and treatment adherence in children aged 5 to 16 years old, with partly controlled or uncontrolled asthma requiring treatment with inhaled corticosteroids. The main questions it aims to answer are: * Does the use of a digital inhaler improve adherence to inhaled corticosteroids and asthma control in children? * Which biomarkers could support diagnosis and help predict treatment responses in children with asthma? * How do environmental factors influence asthma control and treatment outcomes? Researchers will compare adherence to inhaled corticosteroid therapy between children using a new digital inhaler (Whizz spacer) and those using a standard, non-digital inhaler (AeroChamber Plus® Flow-Vu®) to see if the digital inhaler improves treatment administration and asthma control. They will quantify inflammatory markers in biological samples from asthmatic children and children without respiratory disease, to find biomarkers linked to disease and treatment response. Participants will: * Use the Whizz spacer or the AeroChamber Plus® Flow-Vu® during 12 weeks for corticosteroid inhalation, and complete daily a study diary to follow treatment administration. * Complete asthma control and quality of life questionnaires and have an evaluation of asthma control through GINA score at baseline, 6 and 12 weeks. * Undergo spirometry tests and FENO measurements at baseline and 12 weeks. * Give biological samples at baseline and 12 weeks. * Collect children's bedroom dust samples at baseline. * Wear a bracelet for 7 days at baseline and 12 weeks to monitor physical activity.

ASMact: Study on Management of Bronchial Asthma

Standardization According to GINA 2025 Recommendations for the Treatment, Management, and Follow-up of Acute Asthma Attacks: Observational, Multicenter Cohort Study.

PremaBiom: Metatranscriptomics of the Respiratory Microbiome to Predict the Occurrence of Bronchopulmonary Dysplasia in Preterm Infants

The goal of this clinical trial is to understand the impact of respiratory microbiome maturation in respiratory health of preterm infants under 32 gestational weeks. The main questions it aims to answer are: * What is the role of microbiome maturation in respiratory health (development of bronchopulmonary dysplasia, childhood asthma and viral respiratory infections) of preterm infants ? * Which environmental or health factors are involved in the maturation of the respiratory microbiome ? Participants will undergo follow-up from birth until 3 years of corrected age including nasal swabs, stool samples, and for some of them blood and milk sample.

Effectiveness of an Educational Intervention on Asthmatic Children in Inhaled Technique and Adherence.

The goal of this study is to see if a short educational session and demonstration by a nurse can help asthmatic children (6-17 years-old), under hospital control, to manage their asthma better, to use their inhaler correctly, and to know when it should be used. The main question it aims to answer is how much improvement is reached on asthma self-management. The comparison group is the same group. Researchers will compare results before and after educational intervention.

Remote Monitoring of Asthma in Children and Young People

The objective of this study is to determine whether healthcare data and remotely collected patient data can accurately predict asthma attacks in children and young people aged 5-17 years. The main outcome is: when using this new system, is there a reduction in asthma attacks compared with a historic average. The whole population of children and young people with asthma will have routine healthcare data monitored, with a subset of people with high risk asthma asked to participate in a more detail study involving remotely monitored data.

The Effectiveness of Early Immunisation With Nirsevimab on Preschool Wheezing in France, Based on an Analysis of Data From the French Health System Database.

Early respiratory syncytial virus (RSV) bronchiolitis is a well-known contributing factor of mid- and long-term respiratory sequelae in children such as recurrent lower tract respiratory infections (LRTIs), preschool wheezing (PW) or decreased lung function at older ages. Nirsevimab, a monoclonal antibody against RSV with enhanced neutralizing activity and a prolonged half-life, has shown great potential in reducing short term outcomes such as hospitalization for RSV associated bronchiolitis (estimated adjusted effectiveness against hospitalization to 83.0% (95%CI: 73.4 to 89.2). Other countries that have been using nirsevimab almost exhaustively have reported similar results such as in Galicia. However, prevention of RSV LRTI or delay RSV infection early in life has not been investigated on respiratory manifestations such early wheezing in infancy (ie before 2 years of age) and recurrent wheezing in preschool period (ie between 2 and 6 years old). Some recent data have shown that nirsevimab was associated with a reduction of wheezing in the year following its administration (HR: 0.73; 95% CI, 0.58-0.93). Other data have shown that not being infected by RSV during the infancy was associated with 26% lower risk of 5-year current asthma than being infected (5) giving good rational for preventive strategies against RSV to impact midterm respiratory outcomes such as PW and then asthma. Ongoing observational cohort studies will help investigate the question of mid-term effects, but they will come with a high costs and risk of attrition. Administrative national health claims database could prove to be useful and complementary by studying these types of real world outcomes across lives of children that have been immunized by nirsevimab as shown recently. Therefore, the investigators aim to study the impact of early nirsevimab administration on wheezing manifestations occurring in infancy and beyond during the preschool years. Our primary objective is to see if nirsevimab administration during the first six months of life has an impact on hospitalization for wheezing episodes during the second year of life, based on the hypothesis that infants who had received nirsevimab have reduced hospitalization for wheezing during their second year of infancy.
