Exposure to poor hygiene and early life infections and the risk of wheeze or asthma in Latin American children: a systematic review
نویسندگان
چکیده
Background The asthma epidemic in industrialised countries has been explained by the ‘hygiene hypothesis’, according to which early life infections protect against allergic diseases. However, current high asthma rates in Latin American cities seem to be associated with poor hygienic conditions, overcrowding and infections. The aim of the review was to summarise the role of poor hygiene exposures and early life infections on the risk of developing wheeze/asthma amongst Latin American children.

متن کاملNon-atopic asthma is associated with helminth infections and bronchiolitis in poor children Short title: Non-atopic asthma in children
Asthma is common in urban centers in Latin America, but atopic asthma may not be the main phenotype among children. Helminth infections are highly prevalent in poor populations and we hypothesized that they attenuate allergic asthma, while other factors are related to the expression of a non-atopic wheeze/asthma phenotype. A total of 1982 children aged 10.1 (0.76) years (SD) from Southern Brazi...
