This study aimed to determine whether there is a persistent or different type of airway inflammation in patients with an incomplete reversibility of airflow obstruction (IRAO) despite optimal treatment and if so, whether it is associated with an accelerated decline of pulmonary function. Fifteen asthmatic patients with IRAO, and 23 with complete reversibility of airflow obstruction (CRAO) had a spirometry...
Bronchial biopsies are currently used to study the pathophysiology of airway diseases, and comparisons are often made with biopsies from healthy volunteers. It is therefore important to evaluate the variability in each parameter analyzed in bronchial biopsies of healthy volunteers in order to be able to discriminate significant changes. We analyzed bronchial biopsies of 31 nonsmoking, nonatopic healthy...
Viral respiratory infections in infancy may contribute to the development of airway hyper-responsiveness (AHR) in childhood but their effects on respiratory function at the adult age are still uncertain. A group of 42 subjects aged 17–35 with a pediatrician-made diagnosis of severe bronchiolitis in infancy (Br) were compared for the presence of asthma and AHR to a control group (C) paired for age...
