| Abstract: | Exposure to small-dose environmental agents is a risk factor of immunopathological reactions. The levels of formaldehyde-specific IgE were comparatively analyzed in 50 children of whom 25 live in the area exposed to formaldehyde. Children with varying respiratory allergic reactions comprised a study group. To identify allergen-specific IgE, the authors used a method that determined formaldehyde antibodies by using the tested allergen (formaldehyde on the paper). There were significant group-specific differences in the levels of formaldehyde antibodies (3.8 times higher in the study group than in the controls). Combined therapy substantially reduced specific IgE whose levels returned to the levels observed in the controls. The findings may recommend the use of this test for the diagnosis of immune-depended abnormalities and the evaluation of their effective treatment. |
