Background: The chance of a nonspecific intradermal skin test response at venom concentrations greater than 1.0 microg/mL limits the diagnostic range and can interfere with the diagnosis of some affected patients.
Objective: To compare the diagnostic ranges and clinical detection rates of skin tests using dialyzed yellow jacket venom (DYJV) and undialyzed YJV (UYJV), particularly in patients who have had negative venom skin test results.
Background: The reported frequency of systemic reactions to challenge sting varies greatly.
Objective: To evaluate the interaction of clinical and entomological factors that determine the outcome of a challenge sting.
Methods: Patients allergic to yellow jacket were stung and monitored for systemic reaction.
Background: Children are thought to "outgrow" the allergy to insect stings, but there are no reports documenting the natural history of this reaction. We studied the outcome of allergic reactions to insect stings in childhood 10 to 20 years afterward in patients who had not received venom immunotherapy and in those who had been treated.
Methods: Between 1978 and 1985, we diagnosed allergic reaction to insect stings in 1033 children, of whom 356 received venom immunotherapy.
Background: Sodium hypochlorite (NaOCl), the primary component of household bleach, has been shown to alter the purified mouse allergen Mus m 1, such that antibody recognition, or immunogenicity, is lost. Results of initial experiments suggest that antibody recognition is lost at lower concentrations of NaOCl than those required to fragment Mus m 1.
Objective: We sought to determine whether NaOCl had similar effects on recombinant (r)Fel d 1 and whether the loss of antibody recognition correlated with the loss of biologic activity, as measured with a basophil histamine release assay.
