Intracutaneous injection of autologous serum with specific IgE against penicillin followed by intracutaneous test with penicillin, does not elicit a positive intracutaneous test
نویسندگان
چکیده
Background In patients allergic to penicillin only a minority of those who have specific IgE against penicillin also have a positive intracutaneous test (ICT) to penicillin and vice versa. This is in contrast to findings in patients with allergy to classical type 1 allergens, e.g. grass or peanuts. Besides that, our investigations indicates that histamine is only released in the minority of positive intracutaneous tests. The reason for this is not known. A hypothesis could be that the specific IgE against penicillin measured in serum is not present in the skin. The aim of this project is to investigate, if you by priming the skin with autologous serum in patients with specific IgE to penicillin subsequently are able to develop a positive ICT upon testing.

Is a positive intracutaneous test induced by penicillin mediated by histamine? A cutaneous microdialysis study in penicillin-allergic patients
Background Diagnostic workup of penicillin allergy comprises skin testing with penicillins, and patients are deemed allergic if skin test is positive. However, the literature suggests that skin test-positive patients may be challenge-negative, indicating that the skin test may be falsely positive. Objective To investigate real-time histamine release from a positive intracutaneous test induced...

BACKGROUND Sweating can worsen atopic dermatitis (AD). The purpose of this work was to study the associations between reactivity to autologous sweat and the clinical severity of AD as well as investigate the possible wheal-inducing factors of sweat. METHODS Intracutaneous skin tests with autologous sweat were performed on 50 AD patients and 24 control subjects. In skin biopsies, tryptase and ...

This study was concerned with the correlation between skin test, bronchial provocation test, and histamine release from leucocytes and the serum level of total and allergen-specific IgE in patients atopic to house-dust mite allergen (Dermatophagiodes pteronyssinus) as measured by an intracutaneous skin test. It is concluded that, assuming a positive provocation test to be evidence of allergy, e...

BACKGROUND The diagnosis of PPL (major determinant) and MDM (minor determinant) sensitization as relevant allergens in beta-lactam allergy has been recently hampered by withdrawal from the market of formerly available test kits. We investigated a new PPL/MDM test kit in the work-up of beta-lactam allergy. PATIENTS AND METHODS 15 patients with history of beta-lactam allergy were investigated f...
