[New approaches of inhaled steroid asthma management in mild to moderate asthma].

Inhaled corticosteroids (ICS) are the cornerstone of the management of asthma. Daily use allows to reduce mortality, intensity and frequency of exacerbations, to increase the control of symptoms of asthma and the quality of life of asthmatics patients and to reduce the decline of the lung function. A daily use of a weak dose of ICS allows to control the symptoms of asthma of the vast majority of mild to moderate asthmatics patients who account for about 75-80 % of the French asthmatic patients. An add-on strategy with a combination by ICS/LABA allows to decrease by 20 % the risk of an exacerbation compared with a treatment by CSI in monotherapy. "SMART" which consists in using a fixed ICS/LABA combination as a maintenance and reliever therapy had showed better results in the prevention of exacerbations that the use of the same combination associated with a SABA as a reliever therapy. This strategy is recommended by GINA at the same level of proof as the classical treatment. An "on-demand" use of a ICS/LABA combination according to symptoms is clearly less efficacious in terms of control of the symptoms than the classical strategy by ICS/LABA; but both strategies are identical in terms of prevention of exacerbations. The daily dose of ICS is 4 to 5 times less than in the daily ICS group. The clinical effectiveness and cost-effectiveness of a standard asthma self-management plan that advises patients to temporarily quadrupling the dose of ICS in case of asthma worsening can be an alternative and allow to reduce 20 % of clinically important asthma exacerbations.
