BACKGROUND: Breath sound parameters have been suggested to be new biomarkers of airway function in patients with asthma. METHODS: We investigated the effect of bronchodilation on breath sound parameters in sixty-four children (mean age, 8.9 years; range, 6-16 years) using a breath sound analyzer. The breath sound parameters included frequency limiting 50% and 99% of the power spectrum (F50 and F99 ), roll-off from 600-1200 Hz (slope), and spectrum curve indices such as the ratios of the third and fourth power area to the total area of the power spectrum (P3 /PT and P4 /PT ), total area under the curve (A3 /AT and B4 /AT ), and the ratio of power and frequency at 50% and 75% of the highest frequency of the power spectrum (RPF75 and RPF50 )...

The development of new asthma biologics and receptor blockers for the treatment of paediatric severe asthma raises challenges. It is unclear whether there are sufficient children in Europe to recruit into randomised placebo-controlled trials to establish efficacy and safety in this age group. In February 2016, the European Respiratory Society funded a clinical research collaboration entitled "Severe Paediatric Asthma Collaborative in Europe" (SPACE). We now report the SPACE protocol for a prospective pan-European observational study of paediatric severe asthma...

BACKGROUND: Asthma is characterized by hyperresponsiveness of the airways, and exercise-induced bronchospasm (EIB) is a symptom that limits a large proportion of asthmatic patients, especially children. Continuous positive airway pressure (CPAP) leads to a reduction in the reactivity of the airways. The aim of this study was to evaluate the effect of outpatient treatment with CPAP and bilevel pressure combined with respiratory physical therapy for children and adolescents with asthma following bronchial hyperresponsiveness caused by an exercise bronchoprovocation test...

BACKGROUND: Asthma guidelines guide health practitioners to adjust treatments to the minimum level required for asthma control. As many people with asthma have an eosinophilic endotype, tailoring asthma medications based on airway eosinophilic levels (sputum eosinophils or exhaled nitric oxide, FeNO) may improve asthma outcomes. OBJECTIVE: To synthesise the evidence from our updated Cochrane systematic reviews, for tailoring asthma medication based on eosinophilic inflammatory markers (sputum analysis and FeNO) for improving asthma-related outcomes in children and adults...

AIM: This study evaluated children hospitalised for bronchiolitis at less than six months of age to see if they had reduced lung function in early adolescence. METHODS: We have prospectively followed 166 children hospitalised for infant bronchiolitis in 2001-2004 at Tampere University Hospital, Finland. At 10-13 years of age, flow-volume spirometry was measured in 89 cases and 108 controls without infant bronchiolitis from the local population register. Parameters of flow-volume spirometry before and after bronchodilation were analysed...

BACKGROUND: Maximal lung function in early adulthood is an important determinant of mortality and COPD. We investigated whether distinct trajectories of lung function are present during childhood and whether these extend to adulthood and infancy. METHODS: To ascertain trajectories of FEV1 , we studied two population-based birth cohorts (MAAS and ALSPAC) with repeat spirometry from childhood into early adulthood (1046 participants from 5-16 years and 1390 participants from 8-24 years)...

We have a unique opportunity to significantly reduce the worldwide burden of asthma in children and affect respiratory outcomes in adults. However, this will require a paradigm shift that is directed at altering the natural history of asthma, reducing asthma exacerbations, and preventing long-term adverse outcomes of childhood asthma. Attention should continue to be directed toward minimizing risk, as well as impairment, with a goal to achieve optimal control. Based on several National Institutes of Health studies conducted over the last 10 years, we now have the tools necessary to accomplish this goal...

INTRODUCTION: Severe asthma accounts for 5-7% of all asthma cases. The World Health Organization proposed a follow-up protocol to classify cases into severe, treatment-resistant asthma (STRA) or severe, difficult-to-control asthma (SDCA). OBJECTIVE: To analyze the clinical, functional, and therapeutic characteristics of patients with STRA or SDCA. METHODS: Cross-sectional, observational, and analytical study to assess the diagnosis, the extent of control (clinical and functional), comorbidities, treatment adherence, inhalation technique, and environmental factors in patients with severe asthma...

BACKGROUND: The goals of asthma management aim to control the symptoms and minimize future risk. There is, however, an option to stop controller medication if the patient has been well-controlled for at least 6-12 months. To assess control, both clinical symptom assessment and lung function should be monitored periodically. In practical clinical practice of pediatric patients, lung function is not available at all health centers. OBJECTIVES: to determine lung function with a focus on small airway function and the risk of reversibility among children who have been symptom-controlled...

BACKGROUND: Rhinitis and asthma frequently coexist. Peak nasal inspiratory flow (PNIF) objectively evaluates nasal obstruction. Lower airway flow's impact on PNIF has seldom been analysed in children. We aimed to study the associations between PNIF and: 1)forced expiratory volume in one second (FEV1) and peak expiratory flow (PEF) in children with allergic rhinitis and asthma and healthy controls; 2)allergic rhinitis and asthma control subjective evaluation. METHODS: Sequential assessments of PNIF before and after nasal decongestion and spirometry with bronchodilation test were performed in 65 children (6-12 years) with allergic rhinitis and asthma, and 24 gender, age-matched healthy controls...

BACKGROUND: The transition from early childhood wheezing to persistent asthma is linked to lung function impairment over time. Little is known how the methods used to study lung function at different ages correlate longitudinally. METHODS: Sixty-four children with a history of hospitalization for bronchiolitis before 6 months of age were prospectively studied with impulse oscillometry (IOS) at the mean age of 6.3 years and these preschool IOS results were compared with flow-volume spirometry (FVS) measurements at mean age of 11...
