BACKGROUND: It is considered that farm areas protect young patients from allergy and asthma due to high exposure to endotoxins. Allergen immunotherapy (AIT) is the only treatment of allergy modifying the immune response with the potential to change the natural history of allergic diseases. It seems that studies evaluating the efficacy of immunotherapy in large cohorts of allergic patients living in farm areas are needed to understand the influence of environment on immune response during AIT...

PURPOSE OF REVIEW: Allergen immunotherapy is the only modality that can modify the immune response upon exposure to aeroallergens and venom allergens. This review will update the allergist on recent studies evaluating safety of sublingual and subcutaneous allergen immunotherapy. RECENT FINDINGS: Multiple clinical trials and retrospective studies have been published evaluating overall safety of these therapies. The risk of systemic reactions with subcutaneous immunotherapy remains quite low, but near-fatal and fatal anaphylaxis does occur, requiring physicians to be aware of potential risks for such events...

BACKGROUND: Sublingual immunotherapy (SLIT) is a safe and effective treatment for allergic rhinitis (AR). However, many issues regarding SLIT remain to be resolved, including the optimal timing of administration. This study investigated the effect of time of day on SLIT efficacy with the goal of optimizing the therapeutic outcome. METHODS: We performed prophylactic SLIT at different times of day (10 a.m. or 10 p.m.) in 2 mouse models of AR: an ovalbumin (OVA)-induced AR model and Cry j 1-induced AR model, and compared the effects...

BACKGROUND: Group 2 innate lymphoid cells (ILC2s) are regarded as a novel population of lineage-negative cells that induce innate Type 2 responses by producing the critical Th2-type cytokines interleukin (IL)-5 and IL-13. ILC2s as key players in the development of allergic rhinitis (AR) have been proved, however, the effect of subcutaneous immunotherapy (SCIT) with dermatophagoides pteronyssinus extract (Der p-SCIT) on ILC2s in AR patients is not clear. This study aimed to investigate the response of ILC2s of peripheral blood in house dust mites (HDM)-sensitized Chinese patients with AR who received SCIT with Der P extract...

Despite using lots of progression in hypersensitivity, it is not yet a cure. Current treatment for allergy focuses on two approaches, including treats only the symptoms of allergy by utilizing drugs and the other is desensitization therapy (immunotherapy), which involves administration of specific allergens. The main obstacle to hypersensitivity permanent treatment is the IgE producing subclass of B-lymphocytes which is the source of IgE- producing in hypersensitive patients. Removal of these lymphocytes causes noticeable reduction in the levels of IgE and allergic responses significantly...

Allergic diseases often occur early in life and persist throughout life. This life-course perspective should be considered in allergen immunotherapy. In particular it is essential to understand whether this al treatment may be used in old age adults. The current paper was developed by a working group of AIRWAYS integrated care pathways for airways diseases, the model of chronic respiratory diseases of the European Innovation Partnership on active and healthy ageing (DG CONNECT and DG Santé). It considered (1) the political background, (2) the rationale for allergen immunotherapy across the life cycle, (3) the unmet needs for the treatment, in particular in preschool children and old age adults, (4) the strategic framework and the practical approach to synergize current initiatives in allergen immunotherapy, its mechanisms and the concept of active and healthy ageing...

BACKGROUND: Fish is a frequent elicitor of severe IgE-mediated allergic reactions. Beside avoidance, there is currently no allergen-specific therapy available. Hypoallergenic variants of the major fish allergen, parvalbumin, for specific immunotherapy based on mutation of the two calcium-binding sites have been developed. OBJECTIVE: To establish a mouse model of fish allergy resembling human disease and to investigate whether mouse and rabbit IgG antibodies induced by immunization with a hypoallergenic mutant of the major carp allergen, mCyp c 1, protect against allergic symptoms in sensitized mice...

BACKGROUND: Allergen-specific sublingual immunotherapy is a potential disease-modifying treatment for allergic asthma. Galectin-9 (Gal-9), a β-galactoside-binding protein with various biologic effects, acts as an immunomodulator in excessive immunologic reactions by expanding regulatory T cells (Treg) and enhancing transforming growth factor (TGF)-β signaling. We investigated the efficacy of sublingually administered Gal-9 as an adjuvant to a specific allergen in a Dermatophagoides farinae (Df)-induced mouse model of chronic asthma...

BACKGROUND: Clinical efficacy of pollen allergen immunotherapy has been broadly documented in randomized controlled trials. The underlying clinical endpoints are analysed in seasonal time periods pre-defined on the basis of the background pollen concentration. However, any validated or generally accepted definition from academia or regulatory authorities for this relevant pollen-exposure intensity or period of time (season) is currently not available. Therefore, this Task Force initiative of the European Academy of Allergy and Clinical Immunology (EAACI) aimed to propose definitions based on expert-consensus...

This review forms part of a series of annual updates that summarize the evidence base for atopic eczema (AE). It provides a summary of key findings from 12 systematic reviews (SRs) that were published or indexed during 2014, and focuses on the treatment and prevention of AE. For an update of SRs on the epidemiology, mechanisms of disease and methodological issues, see Part 1 of this update. Although phototherapy and various systemic medications (including ciclosporin, azathioprine and methotrexate) are commonly used to treat AE, many of these have not been robustly assessed in head-to-head randomized controlled trials...

BACKGROUND: Circadian rhythms underlie many immune responses and allergic diseases. Subcutaneous immunotherapy (SCIT) can result in adverse reactions; however, it is unclear whether such reactions have a diurnal pattern. OBJECTIVE: To assess whether the timing of SCIT affects the rate of adverse reactions. METHODS: This study was a retrospective medical record review of adult patients (n = 289) who received SCIT at the Northwestern Medical Faculty Foundation, Chicago, Illinois, during a 10-year period (2004-2014)...

BACKGROUND: Insect bite hypersensitivity is an IgE-mediated dermatitis of horses initiated by bites of midges of the genus Culicoides. Culicoides spp. are not indigenous to Iceland and the prevalence of insect bite hypersensitivity is much higher in horses born in Iceland and exported as compared to Icelandic horses born in a Culicoides rich environment. Immunotherapy is therefore needed. OBJECTIVES: The aim of the study was to express an allergen from Culicoides in barley grain and investigate whether an immune response could be obtained in healthy Icelandic horses by oral treatment with transgenic barley expressing the allergen...

Polybia paulista (Hymenoptera: Vespidae) is a clinically relevant social wasp that frequently causes stinging accidents in southeast Brazil. To date, diagnosis and specific immunotherapy (SIT) of allergy are based on the use of crude venom extracts. Production of recombinant forms of major allergens from P. paulista venom will improve diagnosis and SIT of allergic patients by reducing the incidence of cross-reactivity and non-specific sensitization. Here, we describe the molecular cloning, heterologous expression, purification and IgE-mediated immunodetection of phospholipase A1 (Poly p 1), a major allergen from P...

The last year has seen great progress in the understanding of upper airway disease and in its management. For allergic rhinitis, authors focused on the prediction of and effect on the natural course of disease. New evidence was published for the disease-modifying effect of allergen immunotherapy in terms of avoidance of new sensitizations and prevention of asthma in either randomized or real-life studies. Specifically, for patients with house dust mite allergies, which are often underestimated and difficult to diagnose, the efficacy of SQ house dust mite sublingual immunotherapy tablets has been demonstrated in patients with allergic rhinitis and asthma...

Liquid sublingual allergen immunotherapy (SLIT) has been used off-label for decades, and Food and Drug Administration (FDA)-approved grass and ragweed SLIT tablets have been available in the United States since 2014. Potentially life-threatening events from SLIT do occur, although they appear to be very rare, especially for FDA-approved products. Practice guidelines that incorporate safety precautions regarding the use of SLIT in the United States are needed. This clinical commentary attempts to address unresolved issues including controversy regarding the FDA mandate for the prescription of epinephrine autoinjectors for patients on SLIT; how to approach polysensitized patients; optimal timing and duration of SLIT administration; how to address gaps in therapy; whether antihistamines can prevent local reactions, if certain patient populations (such as persistent asthmatics) should not receive SLIT; and when to instruct patients to self-administer epinephrine...
