Threshold for basophil activation test positivity in neuromuscular blocking agents hypersensitivity reactions
BACKGROUND Several different criteria for the positivity of the flow-assisted Basophil Activation Test (BAT) for the diagnosis of Neuromuscular Blocking Agents (NMBA) hypersensitivity reactions have been used in past studies. Our aims were to determine the threshold for BAT positivity expressed as the stimulation index (SI, calculated as the percentage of activated basophils after stimulation w...
متن کاملBasophil activation test is food adverse reactions
Methods 83 subjects (66/17 females/males) with reported food adverse reactions were included in the study. Eighteen atopic/allergic subjects were included as controls for the foods to which they had reported no reactions. BAT was performed on heparinazed blood incubated with food extracts. CD63 activation marker was evaluated on basophils by flow-cytometry. The stimulation index (SI) was calcul...
متن کاملCutaneous Basophil Hypersensitivity
Delayed onset erythematous skin reactions elicited in guinea pigs early in the course of sensitization with azobenzenearsonate-protein conjugates or with protein antigens in incomplete Freund's adjuvant or in saline were found to have a characteristic morphology which sets them apart from delayed hypersensitivity and the classic antibody mediated reactions. The principle feature was massive der...
متن کاملBasophil hypersensitivity response in rabbits.
A cutaneous basophil hypersensitivity response has been observed in rabbits immunized with bovine serum albumin and challenged intradermally with this antigen 7 days later. The cellular response appears to be similar to cutaneous basophil hypersensitivity reported in guinea pigs and humans. A basophil response was also observed in rabbits immunized with Staphylococcus aureus and challenged with...
متن کاملBasophil Reactivity as Biomarker in Immediate Drug Hypersensitivity Reactions—Potential and Limitations
Immediate drug hypersensitivity reactions (DHRs) resemble typical immunoglobulin E (IgE)-mediated symptoms. Clinical manifestations range from local skin reactions, gastrointestinal and/or respiratory symptoms to severe systemic involvement with potential fatal outcome. Depending on the substance group of the eliciting drug the correct diagnosis is a major challenge. Skin testing and in vitro d...
