Natural History of IgE-Mediated Fish Allergy in Children.

Background: Fish allergy is not uncommon, especially in countries with high fish consumption, it can frequently be severe and may affect dietetic and lifestyle choices. Nevertheless, data on its clinical course and natural history are scarce.

Objective: To describe the natural history of immunoglobulin E-mediated fish allergy and the potential differential reactivity to various fish species and identify prognostic markers in children with confirmed disease.

The prevalence and distribution of food sensitization in European adults.

Background: Complaints of 'food allergy' are increasing. Standardized surveys of IgE sensitization to foods are still uncommon and multicountry surveys are rare. We have assessed IgE sensitization to food-associated allergens in different regions of Europe using a common protocol.

Peanut-specific IgE antibodies in asymptomatic Ghanaian children possibly caused by carbohydrate determinant cross-reactivity.

Background: The prevalence of peanut allergy has increased in developed countries, but little is known about developing countries with high peanut consumption and widespread parasitic infections.

Objective: We sought to investigate peanut allergy in Ghana.

Methods: In a cross-sectional survey among Ghanaian schoolchildren (n = 1604), data were collected on reported adverse reactions to peanut, peanut sensitization (serum specific IgE and skin reactivity), consumption patterns, and parasitic infections.

Molecular characterization of Api g 2, a novel allergenic member of the lipid-transfer protein 1 family from celery stalks.

Scope: Celery represents a relevant cross-reactive food allergen source in the adult population. As the currently known allergens are not typical elicitors of severe symptoms, we aimed to identify and characterize a non-specific lipid transfer protein (nsLTP).

Methods And Results: MS and cDNA cloning were applied to obtain the full-length sequence of a novel allergenic nsLTP from celery stalks.
