- (en) [Cat and dog allergy: what preventive measures can be takien?]. Data on the protective effect of early exposure to cat and dog allergens on the onset and subsequent development of atopic sensitisationand asthma are scant and frequently contradictory. Indeed, the studies that appear to demonstrate a protective effect are mostly retrospectiveand those that are prospective usually contradict them. If early exposure to large quantities of Feld1orCanf1have a protective effecton the development of sensitisation to cat or dog allergens, it is not known how long such protection will last. Concerning the potentialprotective effect of IgG4, while an elevation of IgG anti-Fel d 1 can be found in individuals exposed to large amounts of cat allergen, acausal relationship between these immunoglobulins and the absence of asthma has not yet been demonstrated. Therefore, before giving one’sapproval for the acquisition of a cat or a dog to a pregnant atopic woman, she should be informed that, even if a protective effect does exist,no one knows for how long such an effect will last. Knowing that these animals can live for more than 10 years, the mother’s child couldalso become sensitised to cat or dog allergens. Then, since it appears to have been demonstrated in epidemiological studies and in dailyclinical practice that individuals sensitised and exposed to an allergen increase their chances of developing allergic asthma, it seemsreasonable to advise the pregnant atopic patient against acquiring a cat or a dog.
