Peanut allergy as a trigger for the deterioration of atopic dermatitis and precursor of staphylococcal and herpetic associated infections – case report

Atopic dermatitis (AD) is a multifactorial and chronic disease, with genetic, environmental, immunological and nutritional origins. AD may be aggravated by allergies associated with infections. This study aims to describe a paediatric case of AD in which the peanut allergy was the triggering factor to aggravate the disease, and was also the concomitant precursor of […]

Laboratory, Environmental, and Epidemiologic Investigation and Regulatory Enforcement Actions in Response to an Outbreak of Salmonella Bredeney Infections Linked to Peanut Butter

Background.  In September 2012, the Centers for Disease Control and Prevention (CDC), U.S. Food and Drug Administration (FDA), and state and local partners investigated an outbreak of Salmonella enterica serovar Bredeney linked to peanut butter (PB). Methods.  A case was defined as infection with the outbreak strain of Salmonella Bredeney between June 1, 2012 and […]

Survival of Salmonella in Cookie and Cracker Sandwiches Containing Inoculated, Low-Water Activity Fillings

A study was done to determine the rate of inactivation of Salmonella in cookie and cracker snack sandwiches. Two cookie bases (chocolate and vanilla) and cheese crackers, along with high-sugar chocolate and peanut butter-based crème cookie fillings and peanut butter- and cheese-based cracker fillings, were obtained from commercial sources. Fillings and sandwiches containing fillings that […]

Risk Assessment on Dietary Exposure to Aflatoxin B₁ in Post-Harvest Peanuts in the Yangtze River Ecological Region

Based on the 2983 peanut samples from 122 counties in six provinces of China's Yangtze River ecological region collected between 2009-2014, along with the dietary consumption data in Chinese resident nutrition and health survey reports from 2002 and 2004, dietary aflatoxin exposure and percentiles in the corresponding statistics were calculated by non-parametric probability assessment, Monte […]

The Learning Early About Peanut Allergy Study: The Benefits of Early Peanut Introduction, and a New Horizon in Fighting the Food Allergy Epidemic

Observational studies have explored associations between timing of peanut, egg, and milk introduction and food allergy development, noting significant associations with reduced respective rates of milk, egg, and peanut allergy associated with earlier timing of introduction. Interventional studies developed to more definitively explore these outcomes have been published for egg and peanut, and are ongoing […]

Proteolysis of the peanut allergen Ara h 1 by an endogenous aspartic protease

The 7S and 11S globulins of peanuts are subjected to proteolysis two days after seed imbibition, with Ara h 1 and the arachin acidic chains being among the first storage proteins to be mobilized. Proteolytic activity was greatest at pH 2.6-3 and is inhibited by pepstatin A, characteristic of an aspartic protease. This activity persists […]

Sensitisation to milk, egg and peanut from birth to 18 years: a longitudinal study of a cohort at risk of allergic disease

BACKGROUND: Longitudinal data on the natural history of food sensitisation beyond early childhood are scarce. We aimed to investigate the natural history of milk, egg and peanut sensitisation from infancy to18 years and assess whether early food sensitisation predicted adolescent food allergy. METHODS: Sensitisation to cow's milk, hen's egg and peanut was measured by skin […]

Recent advances in immunotherapy and vaccine development for peanut allergy

Peanut allergy is a common problem and can be the cause of severe, life-threatening allergic reactions. It rarely resolves, with the majority of patients carrying the disease onto adulthood. Peanut allergy poses a significant burden on the quality of life of sufferers and their families, which results mainly from the fear of accidental peanut ingestion, […]
