Cumulative dose response curves to inhaled methacholine were established in 24 "healthy" children of asthmatic parents and 7 healthy children of healthy parents. Atopic children of asthmatic parents demonstrated higher bronchial hyperreactivity (BHR) than nonatopic children. The BHR was about ten times less than in the atopic parents of asthmatic children, indicating marked increase in BHR with...

INTRODUCTION Bronchial asthma is a serious global health problem. 5% to 10% of persons of all ages suffer from this chronic airway disorder. This review article presents important considerations of diagnosis and treatment in view of the current national and international asthma guidelines. METHODS Selective literature review, with attention to the current national and international guidelines...

The aim of the present study was to examine the efficacy of low-dose inhaled budesonide (BUD) administered via Turbuhaler once or twice daily on symptoms, lung function and bronchial hyperreactivity in children with mild asthma. One hundred and sixty-three children (mean age 9.9 yrs, 56 females/107 males) with mild asthma (forced expiratory volume in one second (FEV1) 103% of predicted, morning...

To validate the prevalence rate of symptoms of asthma produced by the phase I ISAAC (International Study of Asthma and Allergies in Childhood) study, hypertonic saline challenge test was carried out during the phase II study at a year after the phase I study. For the phase II study, six middle schools from three cities in the phase I study were selected. Finally, 499 children who responded to b...

Background EIA (Exercise-induced Asthma) can be considered a marker of severity and disease control in asthma. There are several diagnostic tools to evaluate airway hyperresponsiveness in EIA, but it has not been establish the best one. Our objective is to explore bronchial hyperresponsiveness with different lung function measurement techniques among a pediatric population with clinical history...
