PURPOSE OF REVIEW: Currently, dramatic changes in allergy treatment can be observed in many countries: The availability of monocomponent products with pharmaceutical quality for SLIT is likely to have a strong impact on all immunotherapy practices and the specialty in general. The market for patient-named products with allergenic mixtures can be expected to shrink. Allergists are concerned about the possibility that single-source products for immunotherapy might be insufficient to serve the needs of all 'polyallergic' patients...

Hymenoptera venom allergy accounts for approximately 17% of all cases of anaphylaxis. Insect stings are a common occurrence across the world, with significant impact on active duty personnel. Venom immunotherapy (VIT) provides an effective treatment for those with systemic reactions to insect stings and other similar indications. We present a case of severe reaction to hymenoptera venom requiring an epinephrine drip and provide an overview for primary care providers on who should be referred to allergy or an allergist, carry an epinephrine auto-injector, and be a candidate for VIT...

PURPOSE OF REVIEW: The rise in the prevalence of food allergy over the past decades has focused attention of factors that may impact disease development, most notably the gut microbiota. The gut microbial communities play a crucial role in promoting oral tolerance. Their alteration by such factors as Cesarean section delivery, diet and antibiotics may influence disease development. This review highlights recent progress in our understanding of the role of the gut microbiota in the development of food allergy...

Mimotope mapping enables the characterization of allergen epitopes for the development of diagnostic and therapeutic approaches. In the present study, a phage display peptide library was used for mimotope mapping based on the binding of antibodies against the recombinant group 5 allergen from the house dust mite Dermatophagoides farinae (Der f 5), an arthropod that causes indoor allergies worldwide. When three monoclonal anti‑Der f 5 antibodies were used for biopanning, seven mimotopes were identified. Their common subsequence was '‑‑‑[‑A][‑T]W[‑S]H[HSFW][LM][PSKR] [TLV][AST]‑[DP][‑L]‑'...

The incidence of food allergy, a disease characterized by adverse immune responses that can render common foods life-threatening, is rising. Yet our current standard of care is simply avoidance of allergenic foods and administration of emergency medications upon accidental exposure. Significant advances have been made in food allergy oral immunotherapy, which is emerging as a potential preventive and curative treatment for this disease. The fundamental strategy of oral immunotherapy is to mitigate adverse immune responses to allergenic food proteins through repeated exposure; reduced reactivity to food allergens (desensitization) often results, but the establishment of sustained immune unresponsiveness or of permanent resolution (tolerance) is not certain...

The recent paper by Nucera et al., showed that the basophil activation test (BAT) in flow cytometry is able to monitor an acquired tolerance induced by a desensitization treatment in food allergy. The paper by Nucera et al. reported two standpoints in the CD63 response to food allergy and OAT and their large difference in CD63 response before and after suggests for the optimal performance of a CD123/HLADR/CD63 BAT in oral food allergy immunotherapy.

Allergic diseases constitute one of the most common causes of chronic illness in developed countries. The main mechanism determining allergy is an imbalance between Th1 and Th2 response towards Th2. Areas covered: This review describes the mechanisms underlying the natural tolerance to food components and the development of an allergic response in sensitized individuals. Furthermore, therapeutic approaches proposed to manage these abnormal immunologic responses food are also presented and discussed. Expert opinion: In the past, management of food allergies has consisted of the education of patients to avoid the ingestion of the culprit food and to initiate the therapy (e...

BACKGROUND: Outside clinical trials, data on systemic reactions (SRs) due to allergen immunotherapy (AIT) are scarce. METHODS: A prospective, longitudinal, web-based survey of "real-life" respiratory allergen immunotherapy (AIT) clinical practice was conducted in France, Germany and Spain. SRs were recorded and coded according to the Medical Dictionary for Regulatory Activities (MedDRA) and risk factors associated with SRs were identified. RESULTS: A total of 4,316 patients (corresponding to 4,363 ongoing courses of AIT) were included...

Immunotherapy has been employed with great success in the form of vaccination to combat viral, bacterial, and parasitic infection. In this issue of Allergy, Cabauatan et al. describe a novel method of allergen specific immunotherapy using epicutaneous patch vaccination with the recombinant birch pollen antigen Bet v 1 in combination with a heat-labile Escherichia coli toxin (LT) as adjuvant. Patch vaccination with rBet v 1 + LT augmented production of IgG instead of IgE antibodies, inhibiting rBet v 1 sensitization in outbred guinea pigs...

Rhinitis is a common global disorder that impacts on the quality of life of the sufferer and caregivers. Treatment for pediatric rhinitis is empirical and does not include a detailed history of the allergy triggers or allergy testing. Thus, allergen avoidance advice is not tailored to the child's sensitivities, which may result in adenoid hypertrophy. However, infant onset rhinitis, especially its relationship with respiratory viruses, remains to be further clarified. Rhinitis basically involves inflammation of the upper nasal lining, presenting typically with symptoms of runny nose (rhinorrhea), nasal blockage, and/or sneezing...

The majority of allergic subjects are polysensitized. In Europe, allergy immunotherapy (AIT) in these patients is usually limited to their single clinically most troublesome allergy while in the U.S. the immunotherapy prescription usually includes all allergen extracts to which the patient has evidence of clinical sensitivity. Areas covered: This article will review the evidence supporting the U.S. practice. It will also review the major new development in the management of polysensitized patients, the introduction of component-resolved diagnosis (CRD)...

PURPOSE OF REVIEW: To describe recent insights into how molecular diagnosis can improve indication and selection of suitable allergens for specific immunotherapy and increase the safety of this therapy. RECENT FINDINGS: As specific allergen immunotherapy targets specific allergens, identification of the disease-eliciting allergen is a prerequisite for accurate prescription of treatment. In areas of complex sensitization to aeroallergens or in cases of hymenoptera venom allergy, the use of molecular diagnosis has demonstrated that it may lead to a change in indication and selection of allergens for immunotherapy in a large proportion of patients when compared with diagnosis based on skin prick testing and/or specific IgE determination with commercial extracts...

BACKGROUND: We have developed a recombinant B cell epitope-based vaccine (BM32) for allergen-specific immunotherapy (AIT) of grass pollen allergy. The vaccine contains recombinant fusion proteins consisting of allergen-derived peptides and the hepatitis B surface protein domain preS as immunological carrier. METHODS: We conducted a randomized, double-blind, placebo-controlled AIT study to determine safety, clinical efficacy and immunological mechanism of three subcutaneous injections of three BM32 doses adsorbed to aluminum hydroxide versus aluminum hydroxide (placebo) applied monthly to grass pollen allergic patients (n=70)...

Food allergy has grown in rapidly in prevalence, currently affecting 5% of adults and 8% of children. Management strategy is currently limited to 1) food avoidance and 2) carrying and using rescue intramuscular epinephrine/adrenaline and oral antihistamines in the case of accidental ingestion; there is no FDA approved treatment. Recently, oral, sublingual and epicutaneous immunotherapy have been developed as active treatment of food allergy, though none have completed phase 3 study. Efficacy and safety studies of immunotherapy have been variable, though there is clearly signal that immunotherapy will be a viable option to desensitize patients...

Chronic asthma is a major health concern for children and adults worldwide. The goal of treatment is to prevent symptoms by reducing airway inflammation and hyperreactivity. Step-up therapy for symptom control involves initiation with low-dose treatment and increasing intensity at subsequent visits if control is not achieved. Step-down therapy starts with a high-dose regimen, reducing intensity as control is achieved. Multiple randomized controlled trials have shown that inhaled corticosteroids are the most effective monotherapy...

Food allergy is an important health issue that affects up to 8 % of the population. The management of allergic patients involves allergen avoidance and prompts the treatment of accidental reactions, as no curative treatment is available so far in routine practice. Oral immunotherapy (OIT) is a promising therapeutic alternative, but it is associated with frequent allergic reactions and cost-effectiveness issues. In hopes of reducing such reactions, a number of trials have used omalizumab, an anti-IgE monoclonal humanized antibody, as adjunctive therapy in OIT...

BACKGROUND: Allergy is a form of immune-mediated exaggerated sensitivity (hypersensitivity) to a substance that is either inhaled, swallowed, injected or comes into contact with the skin. Foreign substances that provoke allergies are called allergens. It has been claimed that multiplex allergen testing may help in diagnosing the cause of symptoms in patients with an unclear cause of allergy or who are allergic to more than one substance. OBJECTIVES: To evaluate multiplex allergen testing [devices that can measure the presence of multiple immunoglobulin E (IgE) antibodies in a patient's blood at the same time], by assessing (1) clinical effectiveness (allergy symptoms, incidence of acute exacerbations, mortality, adverse events of testing and treatment, health-care presentations or admissions, health-related quality of life); (2) effects on treatment (diet, immunotherapy medications, other potential testing); (3) any additional diagnostic information provided by multiplex allergen testing; and (4) cost-effectiveness (cost of different assessment strategies)...
