Background: Human monoclonal IgE antibodies recognizing peanut allergens have recently become available, but we lack a detailed understanding of how these IgEs target allergens.
Objective: To determine the molecular details of the antibody-allergen interaction for a panel of clinically important human IgE monoclonal antibodies and to develop strategies to disrupt disease causing antibody-allergen interactions.
Methods: We identified candidates from a panel of epitope binned human IgE monoclonals that recognize two important and homologous peanut allergens, Ara h 2 and Ara h 6.

Purpose Of Review: There is an increasing awareness among clinicians that industrial and household food processing methods can increase or decrease the allergenicity of foods. Modification to allergen properties through processing can enable dietary liberations. Reduced allergenicity may also allow for lower risk immunotherapy approaches.

Allergic reactions to foods are primarily driven by allergen-binding immunoglobulin (Ig)E antibodies. IgE-expressing cells can be generated through direct switching from IgM to IgE or a sequential class switching pathway where activated B cells first switch to an intermediary isotype, most frequently IgG1, and then to IgE. It has been proposed that sequential class switch recombination is involved in augmenting the severity of allergic reactions, generating high affinity IgE, differentiation of IgE plasma cells, and in holding the memory of IgE responses.

IgE acts primarily via the high affinity IgE receptor (FcεRI) and is central to immediate hypersensitivity reactions (anaphylaxis). However, IgE is also important in the development of chronic hypersensitivity reactions (allergy). In the cardiovascular system, numerous clinical studies have investigated serum IgE levels, mainly in the context of myocardial infarction, and have established a clear association between IgE and ischemic cardiac events.

Background: Chlorhexidine gluconate (CHX), a common cause of perioperative anaphylaxis, is frequently used for skin testing in allergy evaluations. Although CHX's maximal nonirritating concentrations are known, the stability of its dilutions for skin testing remains unexplored, particularly when sterile water for injection (SWFI) or normal saline (NS) are used as diluents.
Objective: Our aim was to evaluate the stability and precipitation of CHX when diluted with SWFI or NS for drug allergy skin testing.
