Allergie : faut-il tuer le chat ? : influence de l’exposition directe au chat sur la survenue des allergies respiratoires

Abstract : The prevalence of allergic diseases has been increasing for 30 years. The role of cat exposure in their development is very controversial. We sought to examine the effect of direct exposure to living cats on the development of respiratory allergies. We conducted a systematic review of longitudinal and cross-sectional studies, published in English or French over the last 20 years. The PubMed, Cochrane and Public Health Databases were used. Thirty-four studies were included: sixteen of the studies found a protective effect of the cat, eight a promoting effect, three a protective or promoting effect according to age of exposure or family history and six studies found no association. We examined separately exposure in the first months of life, during childhood and adulthood, and the role of this exposure on cat sensitization and respiratory symptoms. Cat exposure in infancy and childhood seems to have a protective effect on subsequent sensitization to the cat. Regarding the role of the cat on respiratory symptoms the results seem to move towards a protective or neutral effect. On the other hand, it is impossible to conclude to any role of cat exposure in adulthood. Exposure to the cat alone can't be responsible for the development of respiratory allergy. Although we can’t advise the adoption of a cat to protect against the occurrence of respiratory allergies, our work gives arguments to no longer advise the eviction of the cat for preventive purposes.
