Desensitization of Human Mast Cells: Mechanisms and Potential Utility for Preventing Anaphylaxis

Anaphylaxis Clinical Trial

Official title:
Open-label, Single-center Study of Whether Oral Penicillin Desensitization of Healthy Sensitive Subjects Results in Allergen Cross-desensitization of Mast Cells by Skin Testing and Desensitization of Peripheral Blood Basophils.

Clinical Trial Summary

This is an open-label, single-center study of whether oral penicillin desensitization of healthy sensitive subjects results in allergen cross-desensitization of mast cells by skin testing and desensitization of peripheral blood basophils. The primary endpoint(s) will be PC3 prick skin test values to penicillin, aeroallergen(s) and codeine. Secondary endpoints will be levels of Syk in purified basophils determined by flow cytometry (mean fluorescence intensity) and basophil degranulation (% tryptase release) to anti-FcåRI and to calcium ionophore.
