Management of Pet Allergies in Children in China

AbstractPurpose of the reviewWith the increase in pet keeping among families in China, there has been a corresponding increase in the incidence of allergic diseases such as bronchial asthma and allergic rhinoconjunctivitis. Pet allergies pose important social and health problems, making their management in children crucial.Recent findingsThere is an increasing trend of sensitization to cat and dog dander among Chinese children. The process underlying allergic sensitization is complex and is associated with an IgE-mediated type I hypersensitivity reaction that involves the upregulation of type 2 T-helper (Th2) cells, resulting in Th2 immunity. Compared with traditional serum-specific IgE (sIgE) and skin tests, molecular diagnosis may be better at predicting the progression of diseases. The association between pet keeping and allergic diseases in children remains controversial. Although the hygiene hypothesis is widely accepted in Chinese children, exposure to pets in early life remains a risk factor for allergies.SummaryPet avoidance and allergy immunotherapy (AIT) are recommended for children with pet allergies. However, pet avoidance is difficult to maintain, and AIT is not widely available in China. There is an imbalance between the increase in allergic diseases and the shortage of prevention and treatment options. We hope that advancements in medicine, diagnosis, and healthcare policies will help resolve this issue.
