This review highlights some of the research advances in allergic skin disease, anaphylaxis, and hypersensitivity reactions to foods, drugs, and insects that were reported primarily in the Journal in 2004. Clinical observations included that gastrointestinal symptoms during anaphylaxis are associated with an increased risk for hypotension; recurrence of peanut allergy can occur for about 8% of children who pass an oral food challenge and is associated with continued avoidance of the food after the challenge; seafood allergy is reported by 2.3% of the US population; and determination of the time to resolution of childhood egg and milk allergy might be predictable by means of serial determination of food-specific IgE levels. The comorbid effects of atopic dermatitis (AD) on asthma and the role of topical calcineurin inhibitors in the therapy of AD were also addressed. Basic and translational research observations indicate that improved diagnosis and therapy might become possible on the basis of reported identification or characterization of allergens such as: lipid transfer proteins and birch pollen-related cross-reactive allergens in plant foods; proteins in scorpion venom that cross-react with proteins from imported fire ant; mosquito saliva proteins responsible for systemic anaphylaxis; and IgE binding to quinolones detectable with an in vitro immunoassay. In addition, advances in understanding immune regulation associated with abrogation of oral tolerance in food allergy and of dendritic cell function, modulation of regulatory T cells, and chemokine expression in AD have elucidated possible targets for future intervention.
