Background: Considering the prevalence and associated burden of disease due to bronchial asthma, it is mandatory to obtain an optimal control of the disease and to improve outcomes for these patients. Asthma control and treatment compliance are widely investigated issues around the world. But it has been observed that there is very poor adherence to the inhalational therapy which leads to the s...

OBJECTIVE Few studies have evaluated the incidence of asthma in Spain. Although more children than adults develop asthma every year, no study to date has analyzed the differences in incidence by following 2 age cohorts in the same geographical area. The aim of this study was to determine changes in wheezing, bronchial hyperreactivity, and asthma (in terms of onset, persistence, and remission), ...

In order to determine the effect of drugs on bronchial hyperreactivity in subjects with asthma, 12 atopic asthmatic volunteers underwent bronchial challenge with either histamine or methacholine on three separate days. Before the challenges no medication was given on the first day, on the second 400 microgram of aerosol fenoterol and on the third 5 mg of oral fenoterol were administered. The ae...

Reduction of exposure to sensitising agents causing occupational asthma has been proposed as an alternative to total avoidance in order to minimise the adverse socio-economic impact of the condition. The aim of this systematic review was to compare the effects of these two management options on asthma and socio-economic outcomes. A bibliographic search was conducted to identify studies examinin...

Background Patients with asthma show a marked phenotypic variability, suggesting etiological heterogeneity and strong environmental influences. Bronchial asthma is determined by a complex interaction between genetic and environmental factors, but these mechanisms are not yet elucidated. The aim of the study was to evaluate peculiarities of the TNFa gene polymorphism (-308 G>A) incidence and its...
