Equivalency of Penicilloate Skin Test Reactivity Prepared by a Modified Alkaline Hydrolysis Technique

NCT00589251 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2016-01-11

No results posted yet for this study

Summary

The primary objective of the study is to evaluate the equivalency of the skin test reactivity to penicilloate prepared by our new method of penicilloate preparation versus our old method of penicilloate preparation. The secondary objective of the study is to evaluate the significance of the different diastereoisomers of penicilloate on skin test reactivity.

Conditions

  • Penicillin Allergy

Interventions

OTHER

penicillin skin test

Prick skin tests will be performed on the volar surface of the forearm with each penicilloate and control reagents. The skin test sites will be examined at 15 minutes. A positive test result is defined as a wheal of 3x3 mm or greater with a surrounding zone of erythema. Patients with negative prick test results to penicillin will undergo intradermal testing. Intradermal skin tests will be performed on the volar surface of the forearm. The test reagents will be injected intradermally to produce an initial wheal of 2x2 mm. The skin test sites will be examined at 15 minutes. A positive intradermal test is defined as a wheal of 3x3 mm or greater with a surrounding zone of erythema. In order to ensure patient safety, we will consider using an end point titration technique.
