We aimed to determine the risk of AA and vitiligo associated with AD in a large cohort of US women, the Nurses' Health Study 2. We used logistic regression to calculate age- and multivariate-adjusted odds ratios to determine the risk of incident AA and vitiligo associated with AD diagnosed in or before 2009. A total of 87,406 and 87,447 participants were included in the AA and vitiligo analyses, respectively. A history of AD in 2009 was reported in 11% of participants. There were 147 incident cases of AA and 98 incident cases of vitiligo over 2 years of follow-up...

The activity NF-κB, a pro-inflammatory transcription factor, and its complex modulation play a central role in in inflammatory airways disease such as allergic airway hyperresponsiveness. In a new study, Yokota and colleagues investigated IκBNS - an atypical inhibitor of NF-kB (IκB). Using elegant bone marrow chimera studies in mice, they found that IκBNS differentially modulated NF-κB activity in hematopoietic and non-hematopoietic cells. They also showed that by binding to the promoter region, this nuclear protein directly induced the MUC5AC gene in airway epithelial cells...

BACKGROUND: Ivermectin (IVM) is widely used in both human and veterinary medicine to treat parasitic infections. Recent reports have suggested that IVM could also have anti-inflammatory properties. METHODS: Here, we investigated the activity of IVM in a murine model of atopic dermatitis (AD) induced by repeated exposure to the allergen Dermatophagoides farinae, and in standard cellular immunology assays. RESULTS: Our results show that topical IVM improved allergic skin inflammation by reducing the priming and activation of allergen-specific T cells, as well as the production of inflammatory cytokines...

BACKGROUND: Ecological evidence suggests vitamin D insufficiency (VDI) due to lower ambient ultraviolet radiation (UVR) exposure may be a risk factor for IgE-mediated food allergy. However there are no studies relating directly measured VDI during early infancy to subsequent challenge-proven food allergy. OBJECTIVE: To prospectively investigate the association between VDI during infancy and challenge-proven food allergy at 1 year. METHODS: In a birth cohort (n=1074), we used a case-cohort design to compare 25-hydroxy-vitamin-D3 (25(OH)D3 ) levels among infants with food allergy versus a random subcohort (n=274)...

BACKGROUND: Most studies on the relationship between helminth infections and atopic disorders have been conducted in (sub)tropical developing countries where exposure to multiple parasites and lifestyle can confound the relationship. We aimed to study the relationship between infection with the fish-borne helminth Opishorchis felineus and specific IgE, skin prick testing and atopic symptoms in Western-Siberia, with lifestyle and hygiene standards of a developed country. METHODS: Schoolchildren aged 7 to 11 years were sampled from one urban and two rural regions...

Th2 immunity and allergic immune surveillance play critical roles in host responses to pathogens, parasites and allergens. Numerous studies have reported significant links between Th2 responses and cancer, including insights into the functions of IgE antibodies and associated effector cells in both anti-tumour immune surveillance and therapy. The interdisciplinary field of AllergoOncology was given Task Force status by the European Academy of Allergy and Clinical Immunology in 2014. Affiliated expert groups focus on the interface between allergic responses and cancer, applied to immune surveillance, immunomodulation and the functions of IgE-mediated immune responses against cancer, to derive novel insights into more effective treatments...

There is an ongoing interest in elucidating the causes of allergic diseases. Numerous genetic and environmental risk factors have been identified, including social class, early exposure to allergens, atmospheric pollution, month of birth, Caesarean section, lack of breastfeeding, early and late introduction of solid food and antibiotic use. Many of these are debatable because they could not be reproduced in different settings or do not provide a coherent picture. This article is protected by copyright. All rights reserved...

BACKGROUND: The identification of inflammatory asthma phenotypes, using sputum analysis, has proven its value in diagnosis and disease monitoring. However due to technical limitations of sputum analysis there is a strong need for fast and non-invasive diagnostics. This study included the activation state of eosinophils and neutrophils in peripheral blood to phenotype and monitor asthma. OBJECTIVES: To (1) construct a multivariable model using the activation state of blood granulocytes, (2) compare its diagnostic value with sputum eosinophilia as gold standard and (3) validate the model in an independent patient cohort...

IgE-mediated shellfish allergy constitutes an important cause of food-related adverse reactions. Shellfish are classified into mollusks and crustaceans, the latter belonging to the class of arthropoda. Among crustaceans, shrimps are the most predominant cause of allergic reactions and thus more extensively studied. Several major and minor allergens have been identified and cloned. Among them, invertebrate tropomyosin, arginine kinase, myosin light chain, sarcoplasmic calcium-binding protein, and hemocyanin are the most relevant...

BACKGROUND: It has been hypothesised that n-3 PUFA in breast-milk may assist immune and lung development. There are very limited data on possible long-term effects on allergic disease and lung function. The aim was to investigate associations of n-3 and n-6 PUFA levels in colostrum and breast milk with allergic disease and lung function at ages 12 and 18 years. METHOD: PUFAs were measured in 194 colostrum samples and in 118 three month expressed breast milk samples from mothers of children enrolled in the Melbourne Atopy Cohort (MACS) Study, a high risk birth cohort study...

BACKGROUND AND AIMS: Mast cells are the major effector cells in allergic disorders and many other informatory disorders. The mechanism of mast cell stabilization is not fully understood. Cumulative reports indicate that vitamin D (VitD) contributes to the homeostasis in the body. This study tests a hypothesis that VitD is required in the maintenance of the stability of mast cells. METHODS: The stability of mast cell lines, HMC1 cells, RBL-2H3 cells, p815 cells and mouse bone marrow-derived mast cells (BMMC) was tested in the presence or absence of VitD3...

BACKGROUND: Binding of allergen-specific IgE to its high-affinity receptor FcεRI on basophils and mast cells is a central event in the development of allergies. Exposure of these cells to allergens induces the release of soluble mediators causing allergic symptoms. The inhibitory low-affinity IgG Fc-receptor FcγRIIB is co-expressed on allergic effector cells and has been implicated in negative regulation of immediate hypersensitivity responses. In order to harvest the inhibitory function of this receptor we aimed to select specific binders against FcγRIIB and to generate a bispecific molecule simultaneously targeting FcγRIIB and FcεRI-bound IgE on the surface of allergic effector cells...

The Blomia tropicalis (Blo t) mite species is considered a storage mite in temperate climate zones and an important source of indoor allergens causing allergic asthma and rhinitis in tropical and subtropical regions. Here, we report the crystal structure of one of the allergens from Blo t, recombinant proBlo t 1 (rproBlo t 1), determined at 2.1 Å resolution. Overall, the fold of rproBlo t 1 is characteristic for the pro-form of cysteine proteases from the C1A class. Structural comparison of experimentally mapped Der f 1/Der p1 IgG epitopes to the same surface patch on Blo t 1, as well as of sequence identity of surface-exposed residues, suggests limited cross-reactivity between these allergens and Blo t 1...

BACKGROUND: Systemic low-grade inflammation has been demonstrated in a range of the frequent noncommunicable diseases (NCDs) proposing a shared mechanism, but is largely unexplored in relation to allergic sensitization. We therefore aimed to investigate the possible association with childhood allergic sensitization. METHODS: High sensitivity C-reactive protein (hs-CRP), interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α) and chemokine (C-X-C motif) ligand 8 (CXCL8) were measured in plasma at age 6mo (N=214) and 7yrs (N=277) in children from the Copenhagen Prospective Studies on Asthma in Childhood2000 (COPSAC2000 ) birth cohort...
