BACKGROUND: Modes of infant feeding such as direct and indirect breastfeeding, and formula feeding, and their combinations may play a role in child health. OBJECTIVE: The aim was to investigate which feeding patterns in the first six months pose risks for eczema/skin allergy in children up to 6 years compared to direct breastfeeding for at least 3 months. METHODS: The Infant Feeding Practices Study II in the United States and its 6-year follow-up provided data on feeding modes in infancy and doctor's diagnosed eczema/skin allergy in the first 6 years of life (1,387 infants), based on parental reports...

BACKGROUND: Food allergy is an increasingly common health problem in Western populations. Epidemiological studies have suggested both positive and negative associations between food allergy and infection with the gastric bacterium Helicobacter pylori. OBJECTIVE: The objective of this work was to investigate whether experimental infection with H. pylori, or prophylactic treatment with H. pylori-derived immunomodulatory molecules, affects the onset and severity of food allergy, either positively or negatively...

BACKGROUND: An omalizumab treatment and a high maintenance venom dose may both help to prevent recurrent systemic allergic reactions (SAR) to venom immunotherapy (VIT). The effectiveness of this combination therapy, however, is unclear. OBJECTIVE: We wanted to explore the possibility whether a temporary treatment with the anti-IgE antibody omalizumab, combined with a VIT using an elevated maintenance dose of >100 μg venom may establish a permanent tolerance of maintenance VIT...

BACKGROUND: Workers exposed to laboratory animals have a high risk of developing laboratory animal allergy (LAA). Atopy seems to be the main risk factor for LAA. We hypothesized that occupational sensitization is a better predictor for the development of asthma, rhinitis and bronchial hyperresponsiveness than common sensitization. OBJECTIVE: To investigate the association between occupational sensitization to laboratory animals and clinical outcomes. METHODS: This was a cross-sectional study performed at two universities on students and employees dealing with small rodents...

BACKGROUND: Epidemiological evidence from developed countries indicates that Helicobacter pylori infection correlates with a reduced risk of atopy and allergic disorders, however limited data are available from low-income countries. OBJECTIVE: We examined associations between H. pylori infection in early childhood and atopy and reported allergic disorders at the age of 6.5 years in an Ethiopian birth cohort. METHODS: A total of 856 children (85...

Ru-Xin Foong, Helen Brough
The presence of peanut allergy has increased over the years and still remains one of the most common causes of food-related anaphylaxis. The way in which peanut sensitization occurs has been explored, such as via maternal consumption in pregnancy, via breast milk and through a disrupted skin barrier. It has previously been shown that environmental exposure to aeroallergens in household dust can be a risk factor for the development of allergic asthma. However, it is likely that the combination of cutaneous sensitisation via a disrupted skin barrier (i...

BACKGROUND: The application of specific immunotherapy to stimulate oral tolerance towards food allergens is hampered by the high frequency of adverse side effects and the excessive duration of the treatments. OBJECTIVE: In this work, a hydrolysate of ovalbumin with pepsin (OP), selected for its low IgE reactivity and Th2-stimulating capacity, was assayed for its ability to prevent and treat allergy to egg white (EW). METHODS: As a first step, the safety of OP, in terms of the absence of sensitizing and eliciting potential, was evaluated in BALB/c mice...

Sarah Beck, Aarnoud P Huissoon, Richard L Baretto, Mamidipudi Thirumala Krishna
We congratulate the authors for producing a comprehensive guideline on the diagnosis and management of peanut and tree nut allergy(1) This is likely to improve care via standardisation across the UK NHS Allergy services. Several studies have illustrated the benefit of component resolved diagnostic (CRD) testing by enhancing the accuracy of peanut and hazelnut allergy diagnosis and aiding the process of risk stratification. However, most of these data are derived from studies carried out on children in Europe and USA with little evidence from adults and the British population...

BACKGROUND: Allergen immunotherapy uses pharmaceutical preparations derived from naturally occurring source materials, which contain water-soluble allergenic components responsible for allergic reactions. The success of in vivo and in vitro diagnosis in allergen sensitization and allergen immunotherapy largely depends on the quality, composition and uniformity of allergenic materials used to produce the active ingredients, and the formulation employed to prepare finished products. OBJECTIVES: We aimed to examine the factors influencing batch-to-batch consistency of Jack Jumper (Myrmecia pilosula) ant venom (JJAV) in the form of Active Pharmaceutical Ingredient (AI) and informed whether factors such as temperature, artificial light and container materials influence the quality of JJAV AIs...

BACKGROUND: There is now increasing evidence that asthma and atopy originate in part in utero, with disease risk being associated with the altered epigenetic regulation of genes. OBJECTIVE AND METHODS: To determine the relationship between variations in DNA methylation at birth and the development of allergic disease, we examined the methylation status of CpG loci within the promoter regions of Th1/2 lineage commitment genes (GATA3, IL-4, IL-4R, STAT4 and TBET) in umbilical cord DNA at birth in a cohort of infants from the Southampton Women's Survey (n=696) who were later assessed for asthma, atopic eczema and atopy...

Food allergies (FAs) are of increasing public health concern and are characterized by a large spectrum of diseases. Their diversity is well known for immunologic pathways (IgE, non-IgE mediated FAs), and natural history. Many other factors and patient characteristics are involved including type of food, exposure route, allergic comorbidities, gender, racial and ethnic backgrounds, co-factors and health conditions. Food allergen components and sensitization profiles are also involved in FA phenotypes. A new approach to chronic disorders based on the identification of phenotypes through extensive knowledge of all the complex components is also applicable to FAs and could lead towards integrative care management...

BACKGROUND: Subcutaneous allergen immunotherapy with grass pollen allergoids has been proven to be effective and safe in the treatment of patients with allergic rhinoconjunctivitis. Based on the extensive cross-reactivity among Pooideae species, it has been suggested that grass pollen extracts could be prepared from a single species, rather than from a multiple species mixture. OBJECTIVE: To find the optimal dose of a Phleum pratense allergoid preparation and compare its efficacy and safety to a 6-grass pollen allergoid preparation...

BACKGROUND: An association between dampness at home and respiratory conditions has been convincingly demonstrated in children. Fewer studies have been performed in adults and data are lacking for chronic rhinosinusitis (CRS). With a prevalence of 10.9% in Europe, CRS imposes a significant burden on quality of life, as well as economy. OBJECTIVE: Our aim was to study CRS and other respiratory conditions in relation to dampness at home in a representative sample of adults...

BACKGROUND: Cow milk (CM) allergy (CMA) affects up to 3% of the pediatric population and recent data suggest that only about 50% will outgrow by age 8. Oral immunotherapy (OIT) is a type of immune-modulating treatment that is able to induce desensitization to food allergens, to increase tolerance threshold, to reduce the risk of anaphylaxis, and to improve the patient's quality of life. The examination of the immunological changes observed during the establishment of food allergy (FA) desensitization in FA patients is a window into the pathogenesis of food allergy and food tolerance development...
