Background: Atopic dermatitis (AD) can occur after contact with aeroallergens like house dust mites, pollen, and animal dander. Despite its controversial diagnostic value, the atopy patch test (APT) has been used as an important tool in the diagnosis of AD caused by house dust mites. Here, we present a meta-analysis comparing APT to the common skin prick test (SPT) in the diagnosis of mite-induced AD. Methods: A structured search was performed using online databases and bibliographies published as of April 30, 2017...

Atopic dermatitis (AD) is a chronic relapsing skin disease, characterized by flare-up due to the exposure to allergens in patients sensitized to them. Currently, therapy of AD is mainly based on symptomatic treatment and avoidance of irritating/allergenic factors, house dust mites being particularly important. Allergen immunotherapy (AIT) is suggested to be the only etiologic treatment, to modify the natural history of the disease. Areas covered: The aim of this review is investigating the putative role of AIT in AD through the evaluation of the most recent scientific literature...

Atopic dermatitis (AD) is a common disease affecting up to 10-20% of the population with the largest disease burden in childhood. Treatment options include basic emollient treatment, topical as well as systemic immunosuppressants. The pathogenesis is complex and among various triggers, genetic predisposition and immunological alterations contribute to development of disease. Atopy is common in patients with AD and many patients have high levels of Immunoglobulin E (IgE), some of which recognizes exogenous or auto/self-allergens...

Over the past few decades, allergic diseases have become increasingly prevalent worldwide. House dust mite (HDM) is the most important domestic source for allergic diseases such as allergic rhinitis, asthma and atopic dermatitis. Dermatophagoides pteronyssinus (Der p) is the major environmental allergen in southeast Asia because of the humid and warm environment is suitable for its growth. In the recent year, role of HDM allergen in allergic inflammation through innate immune system has been well studied. Toll-like receptors (TLRs), protease-activated receptors (PARs) and DC-SIGN could be activated by different HDM major allergens and proinflammatory cytokines also be upregulated...

We previously reported the inhibitory effect of chrysin, a natural flavonoid plentifully contained in propolis, vegetables and fruits, on the mast cell-mediated allergic reaction. In this study, we evaluated the effect of chrysin on atopic dermatitis (AD) and defined underlying mechanisms of action. We used an AD model in BALB/c mice by the repeated local exposure of 2,4-dinitrochlorobenzene (DNCB) and house dust mite (Dermatophagoides farinae extract, DFE) to the ears. Repeated alternative treatment of DNCB/DFE caused AD-like skin lesions...

BACKGROUND: Several genetic variants have been associated with the susceptibility to allergic disease in adults, but it remains unclear whether these genetic variants are also associated with the onset of allergic disease early in life. The aim of this study was to develop a genetic risk score (GRS) for allergy based on findings in adults and study its predictive capacity for allergy in children. METHODS: A GRS was constructed based on 10 SNPs previously associated with allergies in adults...

BACKGROUND: House dust mite/HDM atopy patch test/APT elicits positive reactions in a high fraction of atopic dermatitis/AD and healthy individuals. Experimental systems for new-onset/chronic AD are needed to support rapid therapeutic development, particularly since animal models representing human AD are lacking. While HDM APT has been considered to simulate AD, its suitability to model AD's emerging Th2/Th22 phenotype with Th1 and Th17 components is unknown. OBJECTIVE: To assess whether HDM APT reproduces AD...

BACKGROUND: IgE-reactivity to antigens from gram-positive and negative bacteria is common in patients suffering from respiratory and skin manifestations of allergy, but the routes and mechanisms of sensitisation are not fully understood. The analysis of the genome, transcriptome and microbiome of house dust mites (HDM) has shown that S. aureus and E. coli species are abundant bacteria within the HDM microbiome. Therefore, our aim was to investigate if HDM are carriers of bacterial antigens leading to IgE sensitisation in patients suffering from atopic dermatitis...

House dust mites have been implicated in the etiology and exacerbation of atopic dermatitis. Diverse factors contribute to house dust mite allergenicity through the activation of innate immunity. We investigated whether Dermatophagoides farinae extract (DFE) allergens mediate innate immune activation through specific toll-like receptors (TLRs) in epidermal keratinocytes, a DFE-induced murine atopic dermatitis model, and human atopic dermatitis lesions. DFE activated the expression of TLR1, TLR6, IL-25, and IL-33 in human primary keratinocytes and HaCaT cells...

Human leukocyte antigen (HLA)-G is an immune checkpoint molecule that plays critical roles in immune response and in triggering inhibitory signaling to immune cells such as T cells, natural killer cells, and antigen-presenting cells. Thus, the application of HLA-G can be considered for treating immune response-related inflammatory disorders. We have previously reported that treatment with HLA-G1 and HLA-G2 ameliorates the joint swelling associated with collagen-induced arthritis of DBA/1 mice, an animal model for rheumatoid arthritis...
