A citrus fruit-exclusion diet in sensitive patients and its influence on specific antibodies.
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.
