Asthma and the respiratory microbiota: a close relationship
Asthma is considered a major public health issue. Since the end of the 20th century, there has been an increase in the prevalence of this condition which affects all generations, and particularly children. The disease causes varying degrees of respiratory difficulties depending on severity. Fortunately, there are treatments for acute attacks and disease-modifying treatments, which provide asthma patients with a better quality of life. This chronic inflammation of the bronchi has a multifactorial etiology: genetic, immunological and environmental. There are more and more breakthroughs in this growing research area, in particular with regard to the role of the different microbiota that are potentially involved–pulmonary, nasal, intestinal–in the onset and course of the disease. The first results allow new preventive and therapeutic avenues to be considered in the coming years.
