The prevalence of peanut allergy (PA) in Africa is unknown but anecdotal reports suggest the prevalence to be lower than that experienced in developed countries, which report a prevalence of approximately 1.5%. Countries in Africa and Asia, as well as Israel, where the early consumption of high-dose peanut protein is routinely practised, have enjoyed a low prevalence of peanut allergy, e.g. 0.0...

BACKGROUND Allergy to peanuts and tree nuts (TNs) is the leading cause of fatal allergic reactions in the United States, and the prevalence appears to be increasing. OBJECTIVES We sought to determine the US prevalence of self-reported peanut, TN, and sesame allergy in 2008 and compare results with comparable surveys conducted in 1997 and 2002. METHODS A nationwide, cross-sectional, random t...

The role of antibody avidity in allergy is poorly understood and there is no existing literature describing antibody avidity in food allergy. The main aim of this study was to investigate IgE and IgG avidity to a total peanut protein extract (TPPE) and purified Ara h 2 in a group of well-characterized peanut allergic individuals. Forty peanut allergic patients underwent a double-blind placebo-c...

RESULTS. A total of 181 schoolchildren (0.83%) in the 3 districts were dispensed injectable epinephrine during the school year studied. Diagnoses listed for the prescription of epinephrine included peanut/tree nut allergy (65%), stinging-insect allergy (19%), seafood allergy (6%), and egg or dairy allergy (3%). A miscellaneous group (7%) included diagnoses for latex, chocolate, pollen, fruit, c...

: Peanut allergies have been increasing in prevalence in most industrialized countries. Onset is typically in early childhood, with a trend towards earlier ages of presentation. The allergy is lifelong in most affected children, although 15-22% will outgrow their peanut allergy, usually before their teenage years. Manifestations of peanut allergy range from mild to severe, and risk factors pred...

Background: Food allergies represent a growing public health concern worldwide. For many people, peanut is a considered one of the basic foods, while for food industry, groundnuts are the cheapest substitute for other nuts. They are added to many goods. The aim of the study is to portray the “peanut culture” in Poland, by reporting perceptions of an ordinary consumer as regards peanuts, peanut ...

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...

Rationale There has been an incremental increase in peanut allergy worldwide in recent decades. Unlike other major food allergens, peanut allergic children are unlikely to acquire tolerance in childhood. Peanut and treenuts are the most common foods implicated in food induced anaphylaxis. We use the data gathered from a large unselected Irish birth cohort study to assess whether screening for P...

The Addendum Guidelines for the Prevention of Peanut Allergy in the United States-Report of the NIAID-Sponsored Expert Panel were developed to build on previous food allergy guidelines after several key studies demonstrated the benefit of early introduction of allergenic foods. These landmark studies including the Learning Early about Peanut (LEAP), LEAP-On and Enquiring about Tolerance trials ...

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...
