Differentiating the cellular and humoral components of neuromuscular blocking agent-induced anaphylactic reactions in patients undergoing anaesthesia

Abstract: Our results indicate that NMBA-related anaphylaxis requires not only IgE NMBA reactivity, but also altered cellular reactivity in the patient. The latter may be demonstrable by testing basophils from the patient, a skin test with (steroidal) NMBA, or both.

“…This suggests that skin tests with rocuronium might not indicate IgE-mediated allergy, while skin tests to succinylcholine, a drug not acting on the MRGPRX2 receptor but sharing the QA epitope with rocuronium, could be more reliable for true NMBA IgE hypersensitivity. It also shows that IgE to rocuronium might be of lesser clinical relevance, as shown in other studies [43,52]. However, whether skin test with NMBA at correct concentrations may still be of value for IgE-mediated hypersensitivity, remains matter of debate.…”

“…In a study investigating the cellular and humoral components of NMBA-induced anaphylactic reactions, the correlation between skin test reactivity to rocuronium and IgE to rocuronium was low. In contrast, striking correlation between IgE to rocuronium and skin test reactivity to succinylcholine was found ( p < 0.001) [52]. This suggests that skin tests with rocuronium might not indicate IgE-mediated allergy, while skin tests to succinylcholine, a drug not acting on the MRGPRX2 receptor but sharing the QA epitope with rocuronium, could be more reliable for true NMBA IgE hypersensitivity.…”

“…In some conditions, such as bacterial colonization, or more extreme situations, such as CD4 deficiency, IgE can be produced in the absence of T cell help [35]. These B cells produce “natural” antibodies with a broad specificity and may be the precursors of isotype-switched B cells producing antibodies to glycans such as the antibodies to the galactose-alpha-1,3 galactose epitope [36, 37] and low-molecular compounds such as quaternary ammonium compounds related to muscle relaxants [38, 39] and drugs like pholcodine [4043]. …”

“…2 -4 Immunoglobulin E (IgE) antibodies to rocuronium have been reported in 48% of serum samples from patients with allergies to neuromuscular blocking agents, although only a small proportion of such IgEpositive patients will actually develop anaphylaxis. 5 6 We report three cases of suspected sugammadex-induced hypersensitivity reactions occurring between July 2010 and June 2011. These events developed immediately after the administration of sugammadex, with varying degrees of severity.…”
