Non-IgE-Dependent Hypersensitivity to Rocuronium Reversed by Sugammadex: Report of Three Cases and Hypothesis on the Underlying Mechanism

Abstract: We present 3 cases of pseudoallergic (anaphylactoid) reactions to perioperatively administered rocuronium, which rapidly resolved after sugammadex injection. Allergological workup showed no evidence for immediate-type hypersensitivity to the drugs used for anesthesia, including rocuronium. However, rocuronium induced an irritative reaction in skin tests in all 3 patients and in 3 healthy individuals. This reaction was specifically suppressed by adding sugammadex at a 1:1 molecular proportion to rocuronium befo… Show more

“…However, vitamin K 1 itself does not induce pseudoallergy; the trigger may be the solubilizer. Perioperatively administered rocuronium can induce pseudoallergy via the non-IgE mediated Mas-related G protein-coupled receptor member X2, which activates mast cell degranulation [69]. …”

“…The neuromuscular blocking agent rocuronium may cause IgE-mediated anaphylaxis as well as non-IgE-mediated hypersensitivity reactions that can be reversed by sugammadex, suggesting a non-IgE-mediated MRGPRX2- (Mas-related G-protein-coupled receptor member X2) triggered mast cell degranulation induced by rocuronium [92]. In cases of rare, immediate-type reactions to heparins that can be identified by skin prick testing, alternative therapies with unfractionated heparins or fondaparinux have been recommended [93].…”

“…The most important hypotheses for these false-positive sIgE results are an elevated total IgE [65] and intake of the opiate antitussive pholcodine [70]. Alternatively, as recently stressed by Spoerl et al [3], IDHR to NMBA such as rocuronium might occur independently from IgE/FcεRI cross-linking and relate to MRGPRX2-mediated activation of mast cells [2] and, therefore, not be depicted by sIgE assays.…”

“…Today, two distinct types of IgE-mediated bovine gelatin allergy are recognized: genuine gelatin allergy that results from sensitization to the protein part of the molecule; and gelatin allergy resulting from a sensitization to a glycan moiety of the molecule, i.e. galactose-α [1, 3] -galactose (α-gal) [9597], as first described by Chung et al [98] and Commins et al [99]. To our knowledge, there are no studies that have determined the diagnostic accuracy of sIgE gelatin.…”
