Eleven patients with a history of anaphylaxis, positive reactions to skin tests, and specific IgE antibody to wasp venom underwent hyposensitisation in a six hour procedure. No general reactions occurred. Complement activation and proteinuria could not be shown. The patterns of specific IgE, IgG1, and IgG4 were as described in other procedures--namely, IgE increased sharply and then decreased; ...
Similarly to other medications, vaccines may be responsible for allergic reactions. Although IgE-mediated allergies to vaccine are extremely rare, they are clearly overdiagnosed. Indeed, accurate diagnosis of vaccine allergy is important not only to prevent serious or even life-threatening reactions, but also to avoid unnecessary vaccine restriction. Systematic approaches have been proposed and...
OBJECTIVES/HYPOTHESIS The objective was to determine the agreement of the positive results from a multiple skin prick test (SPT) device with the ability to determine a definable endpoint through intradermal dilutional testing (IDT) to compare semiquantitatively the degree of positivity of SPT results with quantitative results from IDT and to analyze the cost of immunotherapy based on SPT compar...
The authors describe for the first time a case of immediate and generalized reaction to Montenegro skin test with merthiolated antigen. This reaction consisted of generalized cutaneous rash with pruritus, and was treated with oral bromethazine. The pruritus disappeared an hour after medication and the rash 12 hours later.
Dose response relationships and interference of simultaneous skin tests in delayed hypersensitivity.
The relationship between the intensity of the delayed hypersensitivity reaction and the dose of antigen used for its elicitation change with time after sensitization. At three weeks the reactions to 100 mug of egg albumen were little different from those to 1 mug but at 14 weeks 100 mug gave much stronger reactions. This means that to follow the development of a delayed hypersensitivity respons...
The incidence of immune-mediated anaphylaxis during anesthesia ranges from 1 in 10,000 to 1 in 20,000. Neuromuscular blocking agents represent the most frequently involved substances, followed by latex and antibiotics, but every drug or substance used may be involved. Diagnosis relies on tryptase measurements at the time of the reaction and skin tests and specific IgE or basophil activation ass...
Food allergy has an increasing prevalence in the general population and in Italy concerns 8 % of people with allergies. The spectrum of its clinical manifestations ranges from mild symptoms up to potentially fatal anaphylactic shock. A number of patients can be diagnosed easily by the use of first- and second-level procedures (history, skin tests and allergen specific IgE). Patients with comple...
We have previously reported the results of ten years of systematic tuberculin Qsting of kindergarten and first grade children in Kansas City, Missouri. This report adds seven yeas of testing in different age groups (8th and 9th; and 4th and 5th grades). As reported in the previous study, the prevalence rates and conversion rates to tuberculin are markedly different depending on the frequency at...
