Guidelines on the treatment of asthma, allergic rhinitis (AR) and allergen immunotherapy (AIT) lack recommendations for house dust mite (HDM) allergy. An expert panel reviewed current guidelines in the light of new data, to assess whether guidelines could be improved. Most guidelines and key position papers did not provide specific recommendations on treatment of allergic asthma (AA) caused by HDM allergy, although some included AIT as a treatment option for AA in general. Around half of the guidelines stated that AIT with HDM extract was an effective treatment for AR, with several indicating sublingual immunotherapy (SLIT) as an option...

BACKGROUND: Identification of aeroallergen sensitization is important for diagnosis and management of allergic diseases. Immunoglobulin E (IgE) sensitization status is known to change over time. However, few studies have explored changes in sensitization patterns across all age groups. The aim of the present study was to evaluate the changing patterns of in vitro IgE sensitization tests in allergic rhinitis patients across all age groups. METHODS: We recruited all patients who were diagnosed as having rhinitis and who underwent in vitro IgE sensitization testing from 2007 to 2016...

BACKGROUND: Specific immunoglobulin E (sIgE) and sIgG4 to house-dust mite (HDM) major allergens during allergen immunotherapy (AIT) and their clinical relevance remain unclear. OBJECTIVE: To investigate the variation of sIgE and sIgG4 to HDM major allergens and the correlation with clinical responses during AIT in patients with allergic rhinitis. METHODS: Thirty-nine patients with HDM allergy were divided into the AIT group (taking immunotherapy) and the control group (medication only use)...

Allergic conjunctivitis (AC), which may be acute or chronic, is associated with rhinitis in 30%-70% of affected individuals, hence the term allergic rhinoconjunctivitis (AR/C). Seasonal and perennial AC is generally milder than the more chronic and persistent atopic and vernal keratoconjunctivitis. Natural allergens like house dust mites (HDM), temperate and subtropical grass and tree pollen are important triggers that drive allergic inflammation in AC in the Asia-Pacific region. Climate change, environmental tobacco smoke, pollutants derived from fuel combustion, Asian dust storms originating from central/north Asia and phthalates may also exacerbate AR/C...

INTRODUCTION: House dust mite (HDM) allergens are major causes for the development of allergic diseases. A disease modifying effect and clinical benefit of allergen immunotherapy (AIT) has been demonstrated in a number of clinical trials. Clinical trials, however, are carried out in selected populations under specific conditions based on inclusion and exclusion criteria and may not represent the entire patient population from medical practice. Objective of this study conducted in patients with HDM allergy was to systematically collect information about the benefit of AIT under clinical routine conditions...

Major domestic mite allergens are present in feces. We present a detailed 2D-E-MS/MS proteomic analysis of the Dermatophagoides pteronyssinus feces. Precise cultivation yielded a pure fecal extract. We detected differences in fecal allergens/digestive enzymes between D. pteronyssinus and D. farinae using 2D-E fingerprinting, including unique information on species-specific protease isoforms. Proteomic analysis was performed by 2D-E coupled with MALDI-TOF/TOF identification. The species-specific differences in the fecal extracts of the mites were attributed to trypsin-like proteases known as group 3 allergens...

Products manufactured from mass-cultured house dust mites, currently commercialized for the diagnosis and immunotherapy of allergy, are heterogeneous in terms of allergen composition and thus present concerns to regulatory authorities. The most abundant species, Dermatophagoides pteronyssinus (Trouessart) (Astigmata: Pyroglyphidae), produces 19 allergenic proteins. Many of these are putatively involved in mite digestive physiology and metabolism. This study aimed to evaluate the effects of mite-rearing media on allergen production...

PURPOSE OF REVIEW: Allergenic molecules of the house dust mite (HDM) are crucially important indoor allergens, contributing to allergic rhinitis and asthma around the globe. In the past years, recombinant molecules for diagnostics opened new pathways to investigate individual sensitization profiles and new chances for the prevention and treatment of HDM allergy. This review summarizes the latest findings on the evolution of IgE responses towards mite allergens. RECENT FINDINGS: Several cross-sectional and longitudinal studies confirmed the role of Der p 1 and Der p 2 as major allergenic proteins of the HDM...

Serum IgE assay is a mainstay step in the allergy work up. Allergenic extracts and molecular components are available at present. This real life study compared the serum specific IgE levels against allergenic extracts with allergenic molecules in patients allergic to Parietaria, Betulaceae, and mites. This retrospective real life study included 489 subjects with respiratory allergy. Inclusion criteria were 1) documented diagnosis of allergic rhinitis (AR) and/or allergic asthma, and 2) documented allergy to Parietaria judaica (Par j) 2 (216 patients: 112 females, mean age 42 years), or to Betula verrucosa (Bet v) 1 (62 patients: 35 females, mean age 3 years), or Dermatophagoides pteronyssinus (Der p) 1 (211 patients: 107 females, mean age 34 years); and mono-allergy...

BACKGROUND: The indications for Allergen immunotherapy (AIT) in patients suffering from House Dust Mite (HDM)-related allergic diseases are presently based on incomplete data. This is essentially based on the fact that HDM allergy is difficult to evaluate in clinical trials, due to the largely variable allergen exposure and symptoms, and to the long periods of observation needed to assess the effects. In addition, at variance with pollen allergy, in HDM allergy asthma is more prevalent...

Avoidance of allergens in the treatment of asthma has hitherto not achieved significant benefit despite the strong evidence that allergy both increases severity and contributes to exacerbations of asthma. House dust mite, cat and dog allergens are the most common perennial allergic triggers and most avoidance strategies have focused on reducing exposures in bedrooms. Cochrane reviews have suggested that they neither significantly reduce allergen levels nor improve asthma. While the lack of efficacy may be assumed to be a consequence of exposures occurring outside the bedroom, prolonged sleep is associated with increased susceptibility to bronchospasm and airway inflammation...

BACKGROUND: Allergic rhinitis (AR) is a common disorder. The diagnosis is based on the concordance between allergy sensitization and history. Serum allergen specific immunoglobulin E (sIgE) assessment allows characterization of the relevant sensitizing allergens. Presently, Allergic Rhinitis and its Impact on Asthma (ARIA) classification subdivides AR based on symptoms severity and duration. However, the relationship between sIgE levels and symptom severity is still a matter of debate...

In the United States, the Center for Biologics Evaluation and Research of the US Food and Drug Administration regulates biologics used for diagnosis and treatment of allergic diseases. The Code of Federal Regulations 21CFR680.3(e) states that when measured, the potency of an allergenic extract is assessed according to its allergenic activity. As of 2016, 19 allergenic extracts are standardized for potency in the United States. While these standardized extracts constitute a minority of those available, they treat the most prevalent allergies (e...

PURPOSE OF REVIEW: Animal models published within the past 18 months on asthma, food allergy and anaphylaxis, all conditions of rising public health concern, were reviewed. RECENT FINDINGS: While domestic animals spontaneously develop asthma, food allergy and anaphylaxis, in animal models, divergent sensitization and challenge routes, dosages, intervals and antigens are used to induce asthmatic, food allergic or anaphylactic phenotypes. This must be considered in the interpretation of results...

Allergic rhinitis (AR) with or without conjunctivitis (AR/C) is associated with a significant health and economic burden, and is often accompanied by asthma. Pharmacotherapies are the mainstay treatment options for AR and asthma, but guidelines also recommend allergy immunotherapy (AIT). Unlike pharmacotherapies, AIT has the ability to modify the underlying immunologic mechanisms of AR and asthma with the potential for long-term benefits after treatment is discontinued. Immunotherapy may also prevent progression of AR/C to asthma...

OBJECTIVES: Treatment with allergy immunotherapy improves allergic rhinoconjunctivitis, but can also improve comorbidities associated with allergic rhinitis such as asthma. Sublingual immunotherapy (SLIT)-tablets are a convenient and efficacious method of allergy immunotherapy. They are self-administered after the first tablet has been provided under medical supervision. Therapy may elicit local reactions or, rarely, systemic allergic reactions. The objective of this report is to inform healthcare practitioners about the safety and tolerability profile of SLIT-tablets and use this information to provide practical guidance that may inform patients regarding potential adverse reactions and how to manage them...
