BACKGROUND Peanuts are one of the main food allergens, occasionally responsible for life-threatening reactions. Thus, many studies have tried to fi nd a connection between peanut allergy prevalence and processes in the peanut chain that may contribute to the peanut allergenicity. To inform this discussion, this paper outlines experiences in peanut cultivation, trade and processing in Europe, fo...

BACKGROUND The impact of maternal ingestion of peanut during pregnancy and lactation on an offspring's risk for peanut allergy is under debate. OBJECTIVE To investigate the influence of maternal dietary peanut exposure and breast milk on an offspring's allergy risk. METHODS Preconceptionally peanut-exposed C3H/HeJ females were either fed or not fed peanut during pregnancy and lactation. The...

Background: The importance of peanut allergy has not been well recognized in Japanese society. IgE antibody to peanut can be, however, detected in patients without clinical peanut allergy. Methods: Clinical characteristics of 14 patients (aged 1―8 years) with peanut allergy were evaluated. IgE antibodies to peanut from patients with and without clinical peanut allergy were compared with those t...

BACKGROUND Peanut allergy is typically severe, lifelong, and prevalent. OBJECTIVE To identify factors associated with peanut sensitization. METHODS We evaluated 503 infants 3 to 15 months of age (mean, 9.4 months) with likely milk or egg allergy but no previous diagnosis of peanut allergy. A total of 308 had experienced an immediate allergic reaction to cow's milk and/or egg, and 204 had mo...

Currently, the sole strategy for managing food hypersensitivity involves strict avoidance of the trigger. Several alternate strategies for the treatment of food allergies are currently under study. Also being explored is the process of eliminating allergenic proteins from crop plants. Legumes are a rich source of protein and are an essential component of the human diet. Unfortunately, legumes, ...

BACKGROUND Most of the peanut-sensitized children do not have clinical peanut allergy. In equivocal cases, oral food challenges (OFCs) are required. However, OFCs are laborious and not without risk; thus, a test that could accurately diagnose peanut allergy and reduce the need for OFCs is desirable. OBJECTIVE To assess the performance of basophil activation test (BAT) as a diagnostic marker f...

: The objective of this study was to determine the risk of peanut allergy in siblings of peanut-allergic children. In 2005-2006, 560 households of children born in 1995 in the province of Manitoba, Canada, were surveyed. The index children (8-to 10-year-olds) were assessed by a pediatric allergist and had skin-prick testing and/or capRAST for peanut allergy. Surveys were completed by parents fo...

BACKGROUND Ara h2 sIgE serum levels improve the diagnostic accuracy for predicting peanut allergy, but the use of Ara h2 purified protein as a skin prick test (SPT), has not been substantially evaluated. The fraction of exhaled nitric oxide (FeNO) shows promise as a novel biomarker of peanut allergy. Reproducibility of these measures has not been determined. The aim was to assess the accuracy a...

Wheat, cotton, and peanut were arranged in three cropping sequences to determine the effects of fenamiphos (6.7 kg a.i./ha) and cropping sequence on nematode population densities and crop yields under conservation tillage and irrigation for 6 years. The cropping sequences included a wheat winter cover crop each year and summer crops of cotton every year, peanut every year, or cotton rotated eve...
