Early-Life Exposure to Allergens and Bacteria Might Be Beneficial on Recurrent Wheeze生命早期接触过敏原和细菌可能有利于避免哮喘复发

A US study of a birth cohort at high risk for asthma (n = 560) found that in inner-city environments children with the highest exposure to specific allergens and bacteria during their first year were least likely to have recurrent wheeze and allergic sensitization. First-year exposure to cockroach, mouse, and cat allergens was negatively associated with recurrent wheeze. Exposure to high levels of both allergens and specific house dust bacterial content in the first year of life was most common among children without atopy or wheeze. Early exposure to microbes on farms has been linked to protection against asthma and other allergic disease as well.
