ABSTRACT
Introduction and objectives Atopic individuals are characterized by increased IgE production and Th2 response if exposed to certain antigens. It is known that the mother transfers anti-mite antibodies to the fetus and newborn, IgG thru the placenta, and IgA thru breastfeeding, but it is not clear whether there is a protective mechanism mediated by them concerning the development of future allergies. This study aimed to compare the levels of IgA, IgG, and IgE antibodies specific to Der p 1 and Der p 2 between atopic and healthy individuals. Methods Serum samples of 98 patients and 44 healthy controls were subjected to quantification for specific IgE, IgG, and IgA antibodies against Der p 1 and Der p 2 by ImmunoCap® and ELISA, and subjected to statistical analysis as indicated. Results Atopic patients had higher serum levels of IgE, IgG, and IgA specific to Der p 1 and Der p 2. The correlation was more robust between IgE and IgG antibodies. Conclusions Allergic patients produce higher levels of antibodies against Der p 1 and Der p 2 compared with healthy individuals. The mechanisms involved still require detailed studies (AU)
