[Concept of remission in severe asthma].

The use of biotherapies has revolutionized the management of severe asthma. Following a review of asthma pathophysiology, which underpins the development of these new molecules, this article discusses the different types of remission in childhood and adult asthma. The possibilities of achieving remission with each biotherapy and the factors that predict remission will then be developed. Finally, we'll discuss the chances of maintaining good control of the disease after discontinuation of biotherapies, as well as their contribution in terms of systemic and local cortisone sparing.
