Allergy to Neuromuscular Blocking Agents and Pholcodine Exposure (ALPHO)
Anaphylaxis to Neuromuscular Blocking Agents and Pholcodine Exposure. Case-control Study
The main objective of this study is to compare pholcodine exposure in patients having presented with a perianaesthetic anaphylactic reaction to a NMBA (cases) to pholcodine exposure in matched anaesthetised patients with injection of NMBA, who did not present with an anaphylactic reaction (controls).
The secondary objectives of the study are:
- To compare anti-pholcodine IgE, anti-ammonium IV IgE and total IgE levels between the case and control groups.
- To study the concordance between exposure to pholcodine in cases and controls, by means of a patient self-questionnaire on the one hand and, on the other hand, by a computerized drug history, supplemented where relevant by the drug master file.
- To study the impact of taking 1, 2 or 3 sources in account for pholcodine exposition.
- To study the association between exposure to pholcodine and the presence/levels of pholcodine-specific IgE, reflecting sensitisation to pholcodine.
- To study NMBA and pholcodine cross-sensitisation by testing skin reactions to pholcodine in case patients allergic to (at least) one NMBA.
