Abstract
Purpose of Review
The purpose of this study was to systematically review studies conducted between April 2015 and April 2017 on the environmental risks for the development of AD. We sought to identify (1) environmental risks associated with AD, (2) the proportion of studies for each environmental risk, and (3) environmental risks that need further investigation.
Recent Findings
Recent studies have found genetic predisposition and environmental triggers are involved in the pathogenesis of AD. Genome-wide linkage and candidate gene association studies have led to the linkage of at least 11 different chromosomes and 46 genes. However, the discordance in expression of atopy among monozygotic twins suggests an environmental role.
Summary
Our systematic review found significant risk of development of AD in genetically susceptible children with environmental risk factors of maternal atopy, environmental pollutants, food allergy, and early antibiotic exposure. We suggest future research should aim to better identify environmental pollutants that may increase the development of AD in neonates and children.
