Nickel is a widely used material in many industries. Although, there is enough evidence that occupational exposure to nickel may cause respiratory illnesses, allergies and even cancer, it is not possible to stop the use of nickel in occupational settings. Nickel exposure, however, can be controlled and reduced significantly in workplaces. The main objective of this study was to assess if educational intervention of hygiene behaviour could reduce nickel exposure among Indonesian nickel smelter workers. Participants were randomly assigned to three intervention groups (n = 99)...

PURPOSE OF REVIEW: This article summarises recent developments on the prevention of food allergy in terms of the 5 D's of the development of food allergy: dry skin, diet, dogs, dribble, and vitamin D. RECENT FINDINGS: While several advances have improved our understanding of the development of food allergy, few preventive strategies have been implemented beyond changes in infant feeding guidelines. These now state that the introduction of allergenic solids such as peanuts should occur in the first year of life...

PURPOSE OF REVIEW: Molecular allergology uses pure, mainly recombinant and structurally defined allergen molecules and allergen-derived epitopes to study mechanisms of IgE-associated allergy, to diagnose, and even predict the development of allergic manifestations and to treat and prevent IgE-associated allergies. Atopic dermatitis, a chronic inflammatory skin disease is almost always associated with IgE sensitization to allergens. However, also non-IgE-mediated pathomechanisms seem to be operative in atopic dermatitis and it is often difficult to identify the disease-causing allergens...

AIM: Early feeding plays an important role in programming the immune system, particularly the risk of food allergy. There are many infant feeding guides published for consumers available in Australia, with most based on the National Health and Medical Research Council (NHMRC) 2012 Infant Feeding Guidelines for Health Workers and the Australasian Society of Clinical Immunology and Allergy (ASCIA) Infant Feeding Advice for allergy prevention. We sought to compare allergy-specific content of infant feeding educational material written for parents with these two documents...

Asthma is frequently associated with atopy, characterized by the production of specific immunoglobulin E in response to environmental allergens. Currently, two types of allergen immunotherapy (AIT) are used in clinical practice: subcutaneous and sublingual immunotherapy, both accepted as key components of the therapeutic repertoire for allergic rhinitis and conjunctivitis. However, their role in asthma remains controversial. The present document is aimed at providing the clinicians with a review of the evidence on the use of AIT in asthma, focusing on the most relevant aspects of its mechanism of action, its efficacy, and existing data on safety, tolerability, and cost-effectivity, both in pediatric and adult populations...

BACKGROUND: Allergic asthma is a chronic lung disease resulting from inappropriate immune responses to environmental antigens. Early tolerance induction is an attractive approach for primary prevention of asthma. OBJECTIVE: We analysed the mechanisms of perinatal tolerance induction to allergens with particular focus on the role of B cells in preconceptional and early intrauterine immune priming. METHODS: Wild type (WT) and B cell deficient mice received ovalbumin (OVA) intranasally before mating...

BACKGROUND: The relationship between anaphylaxis and cardiovascular events has been reported in the past. While skin and respiratory symptoms are usually the most common and the first to appear, cardiovascular complications play a key role and represent the leading cause of death in anaphylaxis. METHODS: We report 3 episodes of atrial fibrillation triggered by anaphylaxis. Allergy and cardiology studies were performed. In both patients, the etiological agent was identified: Anisakis simplex hypersensitivity and food allergy...

Our previous study reported that Lactobacillus acidophilus(L.acidophilus)  key laboratory of dairy science  (KLDS) 1.0738 had an effective impact on inhibiting β-lactoglobulin (β-lg) allergy. This study further investigated the anti-allergic activity of peptidoglycan (PGN) isolated from KLDS 1.0738. This study aimed to assess whether toll-like receptor 2 (TLR2)/NF-kappaB (NF-κB) signaling activated by PGN was responsible for reducing allergic inflammation.  Our data showed that administration of  L. acidophilus PGN inhibited IgE production and improved the Treg/Th17 balance toward a Treg response in a mouse model of β-lg allergy...

Asthma is a complex, heterogeneous and chronic airway inflammatory disease with different clinical phenotypes caused by diverse triggers and pathophysiological mechanisms. Asthma heritability has been established in many genetic studies but it is evident that only genetic elements are not responsible for the development of asthma. Increasing rate of asthma incidence during past decades has implicated the role of epigenetics in development of asthma. Environmental factors perform as initiator signals through epigenetic mechanisms...

The prevalence of allergic diseases and asthma has dramatically increased over the last decades, resulting in a high burden for patients and health care systems. Thus, there is an unmet need to develop preventative strategies for these diseases. Epidemiological studies show that reduced exposure to environmental bacteria in early life (e.g birth by cesarian section, being formula-fed, growing up in an urban environment or with less contact to various persons) is associated with an increased risk to develop allergies and asthma later in life...

BACKGROUND: Food allergies are a growing health problem and the development of therapies that prevent disease onset is limited by the lack of adjuvant-free experimental animal models. We compared allergic sensitization in patients with food allergy or Wiskott-Aldrich syndrome (WAS) and defined whether spontaneous disease in Was(-/-) mice recapitulates the pathology of a conventional disease model and/or human food allergy. METHODS: Comparative ImmunoCAP ISAC microarray was performed in patients with food allergy or WAS...

BACKGROUND: Aspirin Exacerbated Respiratory Disease (AERD) is a chronic medical condition that encompasses asthma, nasal polyposis, and hypersensitivity to aspirin and other non-steroidal anti-inflammatory drugs. Several previous studies have shown that part of the genetic effects of the disease may be induced by the interaction of multiple genetic variants. However, heavy computational cost as well as the complexity of the underlying biological mechanism has prevented a thorough investigation of epistatic interactions and thus most previous studies have typically considered only a small number of genetic variants at a time...

Skin barrier abnormalities have been suggested to play an essential role in initiation of early atopic dermatitis (AD). Antigen penetration through a compromised barrier likely leads to increased innate immune responses, antigen-presenting cell stimulation, and priming of overt cutaneous disease. In a TH2-promoting environment, T-cell/B-cell interactions occurring in regional lymph nodes lead to excessive IgE switch. Concurrent redistribution of memory T cells into the circulation not only leads to exacerbation of AD through T-cell skin infiltration but also spreads beyond the skin to initiate the atopic march, which includes food allergy, asthma, and allergic rhinitis...

BACKGROUND: Currently, there are no efficient medications available for the prevention and treatment of food allergy (FA). Herbal medicines, including traditional Japanese Kampo medicines (TJKMs), are promising therapeutic drugs. METHODS: We screened 18 TJKMs for treatment of FA symptoms in a mouse FA model induced by ovalbumin (OVA). BALB/c mice were sensitized intraperitoneally by an OVA/aluminum hydroxide gel mixture followed by 4 booster doses of oral OVA and FA symptom induction by 50 mg of OVA...

BACKGROUND: Avoidance of allergen exposure is an effective measure for preventing naÏve and allergic individuals from sensitization (primary intervention) and disease aggravation (secondary intervention), respectively. Regular monitoring of the allergens in the environment is required for the effective intervention. Thus, there is a need for cost-effective test kits for environmental allergen quantifications. OBJECTIVE: To invent a test kit for quantification of cat major allergen, Fel d 1...

Regulatory T cells (Tregs) are critical modulators of immune homeostasis. Tregs maintain peripheral tolerance to self-antigens, thereby preventing autoimmune disease. Furthermore, Tregs suppress excessive immune responses deleterious to the host. Recent research has deepened our understanding of how Tregs function at the ocular surface. This manuscript describes the classification, the immunosuppressive mechanisms, and the phenotypic plasticity of Tregs. We review the contribution of Tregs to ocular surface autoimmune disease, as well as the function of Tregs in allergy and infection at the ocular surface...
