Summary

Direct drug provocation testing, without prior skin or in vitro testing, is the reference standard for confirming the diagnosis of drug hypersensitivity reactions in children reporting mild and delayed-onset reactions. However, optimal protocol(s) have not been standardized. Although a 2-days' provocation testing protocol is effective, increasing its duration (up to 14 days) may improve its diagnosis performance without increasing the risk of severe reactions. However, a prolonged provocation testing could increase the risk of emergence of bacterial resistances in the digestive flora. Longer duration could be associated with the emergence of extended-spectrum betalactamase producing enterobacteria. However, this point has never been confirmed.

The study will include children (0-18 years); referring for histories of mild and delayed-onset reactions to betalactams. drug provocation testing will be performed with the suspected BLs in our department, as in clinical practice. Two groups of patients will be compared: a group performing short provocation testing (arbitrary defined as lasting 1 to 4 days) and a group with prolonged drug provocation testing (arbitrary defined as lasting 5-8 days). A rectal swab will be collected for each patient before the provocation testing, a second one at the end of the provocation testing. Each sample will be analyzed to detect the presence extended-spectrum betalactamase -producing enterobacteria.
