Flow Cytometry Applied to the Diagnosis of Peri-anaesthesic Reactions — CYPREANE  

Allergy Clinical Trial

Official title:
Diagnostic Accuracy of Flow Cytometry Applied to the Diagnosis of Peri-anaesthesic Reactions Induced by Neuromuscular Blockers

Clinical Trial Summary

To assess diagnostic accuracy of flow cytometry applied to the diagnosis of allergy to neuro-muscular blockers and to the determination of the neuro-muscular blocker (NMB) which may be used for an ulterior anaesthesia in case of allergy to one given NMB.

Clinical Trial Description

The flow cytometric protocol used for this study, was based on basophil selection by an anti- CCR3 and the analysis of basophil activation by the respective up and down regulation of the CD63 and IgE markers as described previously. Basophil activation was expressed in percentage CD63 expression on activated basophils and in activation index involving IgE and CD63 markers and calculated by a specific algorithm developed by our group.. Our aim is to test a sufficient number of patients in order to be able to establish the ROC curves related to the allergen type tested and validate the use of an allergen mixture (NMB mix containing the 7 usual NMB at the optimal activation concentrations). Patients will be included during the post-anaesthetic consultation on the basis of the diagnosis of an IgE dependant per-anaesthetic reaction. The allegro-anaesthetist diagnostical habits won't be changed. ;
