background: atopic dermatitis is a major public health problem, often starting in early childhood and sometimes followed by other allergic diseases. although hypersensitivity to foods is assumed to play an essential role in the development of atopic dermatitis in some patients, little is known about common food allergens in iranian children with atopic dermatitis. objectives: this study was des...

Methods We included 60 subjects in different groups: Group 1, peanut and peach allergy; Group 2, peanut allergy and good tolerance to peach; Group 3, peach allergy and good tolerance to peanut; Group 4, good tolerance to peach and peanut. The diagnostic was performed by clinical history, skin prick test and/or double blind placebo controlled food challenge. BAT to Arah1, Arah2, Arah3, Arah6, rA...

Inadvertent exposure to peanut in foods poses health risks for peanut-allergic individuals that can be reduced by improving detection systems for allergen contaminants in food products and manufacturing processes. Detection of peanut in chocolate has been especially difficult. We report the optimization of conditions for measuring a major peanut allergen, Ara h 1, in chocolate with the use of a...

Methods DBPCFC was performed with increasing concentrations of peanut allergen (1 mg to 5 g of peanut) in 42 children with suspected IgE-mediated peanut-allergy. Blood samples were taken for analyses of CD-sens and quantification of IgE-antibodies to peanut and Ara h 1-3, 8-9. Basophils were stimulated in vitro with peanut allergen in descending doses until the threshold sensitivity was reached...

BACKGROUND The relative contribution and the relation between individual peanut allergens in peanut allergic responses is still matter of debate. We determined the individual contribution of peanut proteins to B, T cell and allergic effector responses in a mouse model for peanut allergy. METHODS Mice were immunized and challenged by oral gavage with peanut protein extract or isolated allergen...

BACKGROUND Peanut allergy is an increasingly common health problem. Current treatment guidelines are based on strict avoidance. However, in the last few years, oral immunotherapy protocols have shown promising results yielding increased tolerance to peanut in allergic children. Adolescence is particularly at risk. METHODS/DESIGN We have designed a randomized, double-blind, placebo-controlled,...

Edible peanut seed represents approximately forty percent of the total mass of the peanut plant at harvest. This plant material is a potential source of nutraceutical compounds. Aqueous acetone was used to extract polar compounds from the leaves and roots of peanut plants, and from the shells of peanut seeds. The antioxidant activities of the extracts using ORAC were determined and compared. Th...

BACKGROUND Double-blinded challenges are widely used for diagnosing food allergy but are time-consuming and cause severe reactions. Outcome relies on subjective interpretation of symptoms, which leads to variations in outcome between observers. Facial thermography combined with nasal peanut challenge was evaluated as a novel objective indicator of clinical allergy. METHODS Sixteen children wi...

BACKGROUND Peanut allergy creates the risk of life-threatening anaphylaxis that can disrupt psychosocial development and family life. The avoidance management strategy often fails to prevent anaphylaxis and may contribute to social dysfunction. Peanut oral immunotherapy may address these problems, but there are safety concerns regarding implementation in clinical practice. OBJECTIVE The purpo...

The relative value of 'Hale' castorbean (Ricinus communis) and 'Pensacola' bahiagrass (Paspalum notatum) as rotational crops for the management of Meloidogyne arenaria and southern blight (Sclerotium rolfsii) in 'Florunner' peanut (Arachis hypogaea) production was studied for 3 years in a field experiment in southeast Alabama. Peanut following 2 years of castorbean (C-C-P) yielded 43% higher th...
