Association between asthma control test, pulmonary function tests and non-specific bronchial hyperresponsiveness in assessing the level of asthma control.

Introduction: Global Initiative for Asthma (GINA) reports emphasize the use of validated and simple tools in order to assess the level of asthma control, as the Asthma Control Test (ACT). However, an ACT does not include assessment of airway inflammation, which is better reflected when measuring nonspecific bronchial hyperresponsiveness (BHR). The authors aimed to find out if the level of asthma control quantified by an ACT correlates with BHR and pulmonary function tests.
