Betalactams are the most frequent cause of hypersensitivity reactions to drugs mediated by a specific immune mechanism. Immediate occur within 1 6 hours after betalactam administration, and generally IgE-mediated. They clinically translate into urticaria, angioedema anaphylaxis. Non-immediate or delayed hour administration. These common usually T cells. The type is maculopapular morbilliform ex...
The antibody IgE plays a central role in allergic disease, functioning principally through two cell-surface receptors: FcℇRI and CD23. FcℇRI on mast cells and basophils mediates the immediate hypersensitivity response, whilst the interaction of IgE with CD23 on B cells regulates IgE production. Crystal structures of the lectin-like `head' domain of CD23 alone and bound to a subfragment of IgE c...
Quinolone hypersensitivity, most of which is immediate type, is rare but has increased in recent years. The pathogenic mechanisms underlying immediate reactions are not defined clearly. This study was aimed to observe the clinical characteristics of immediate hypersensitivity to ofloxacin and to investigate the pathogenic mechanism with detection of serum specific IgE to ofloxacin using an enzy...
