Abstract

Specific hyposensitising therapy for IgE mediated respiratory allergopathies is recognised as an effective therapy able to improve clinical symptoms and bronchial hyperreactivity. IgE synthesis, which is altered in atopic subjects, is regulated by CD4 and partly CD8 lymphocytes. This paper examines the changes in the main T lymphocyte subpopulations in peripheral blood in 10 atopic subjects undergoing specific immunotherapy. The results highlight a significant reduction (p = 0.028) in mean CD4 levels after 6.3 months of treatment. Changes in the other T lymphocyte components and total IgE serum levels were not significant.

Abstract

We describe a qualitative immunoenzymatic method for the determination of specific IgE antibodies in serum or plasma, that can be used as screening in case of suspected IgE-mediated allergy. The comparative analysis of results obtained with this new method and with standard methods for in vitro determination of specific IgE shows a perfect correspondence of the results for both sera with levels of specific IgE or non detectable levels of specific IgE.

Abstract

The AA studied 406 newborn babies during the 1st year of life in order to verify the correlation between atopy risk factors and the appearance of early symptoms, particularly gastroenteric (GE). The results obtained did not demonstrate a significant difference concerning the blood cord IgE level and subsequent appearance of food allergy symptoms, whereas positive familiarity showed a better correlation. No significant difference was observed between breast--or formula--fed infants, or between those weaned before or after the 5th month of life. The comparison of dietary regimen adopted during the 1st quarter in the asymptomatic and atopic children respectively, demonstrated that the presence of predisposing factors influences the appearance of GE symptoms much more than the diet in itself. An allergologic study, randomly performed by Prick-test in 156 cases and by RAST in 200 cases, showed a prevalent, positive response with RAST technique in symptomatic children.
