Abstract:
The presence and kinetics of specific IgE and IgG antibodies against the oranges Citrus aurantium sinensis (CAS) and Citrus silension (CS) were studied in 41 atopic and 20 non-atopic children aged 8-12 years. Diagnostic procedures such as intracutaneous skin tests, IgE PRIST and anti-CAS and anti-CS IgE and IgG RAST were performed in both groups. A citrus fruit-exclusion diet was maintained for 180 days. The comparison of the results before and after the diet showed no significant changes in skin reactivity and RAST values, and even a slight increase was recorded in the latter. We have attempted to explain these puzzling findings.
