High levels of shrimp-specific IgE in association with a positive prick test are not always predictive of a positive immediate response to double blind placebo controlled food challenge with shrimp. The observation that shrimp-sensitive individuals in general have increased levels of circulating shrimp-specific IgG is of interest because antigen/allergen specific IgG subclasses have been associated with adverse reactions to foods. Individuals with a history of shrimp sensitivity had significantly raised shrimp-specific IgG2 and IgG4 compared to shrimp-tolerant individuals. There is a positive correlation with shrimp-specific IgG and IgE levels.Dr. Bennett:
Rationale for IgG and IgE food allergy testing for patients with known adverse shrimp reaction.
