Summary
Several studies have demonstrated the efficacy of asthma treatment but despite being
correctly diagnosed, conveniently prescribed and adherent to the therapeutics, 5% to 10% of
asthmatics do not reach disease control.
The aim of this study is to measure asthma control, evaluate inflammatory and functional
characteristics, describe comorbidities and aggravating factors and phenotypes derived from
the characteristics of a severe asthmatic population followed at an outpatient university
service in Sao Paolo, Brazil.
