title: Classifying asthma severity and treatment determinants: national guidelines revisited.
abstract: Bronchial asthma is an inflammatory disease of the airways manifested physiologically by a widespread narrowing of the air passages. Being an inflammatory disease of the airways, the most effective treatment available for the management of bronchial asthma are anti-inflammatory agents such as corticosteroids. However, it is known that at higher dosage levels, even inhaled corticosteroids have harmful systemic side-effects. Hence, justification of use of high-dose of inhaled corticosteroids can only be made if patients with severe asthma can be accurately identified. For this precise reason, methods have been devised to categorize asthma severity through various National Asthma Management Guidelines. The present guidelines predominantly stress on symptoms and lung functions as the yardstick for determining the severity of asthma attacks and parameters determining airway inflammation have not yet been incorporated into them. However, these guidelines have proved to be fairly accurate in determining asthma severity and in guiding the treatment in these patients and all healthcare personnel are strongly advised to follow them. It is hoped that future guidelines may incorporate measures of inflammation as well, in order to further improve the diagnostic and treatment modalities in these patients.
