Increase in the prevalence of follicular regulatory T cells correlates with clinical efficacy of sublingual immunotherapy with house dust mites. Int Forum Allergy Rhinol 2024; 14:57-67. [PMID: 37345377 DOI: 10.1002/alr.23221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Revised: 06/02/2023] [Accepted: 06/17/2023] [Indexed: 06/23/2023]
Abstract
BACKGROUND Allergic rhinitis (AR) impairs quality of life and affects nearly 40% of the Japanese population. Sublingual immunotherapy (SLIT) is the disease-modifying treatment for AR, but requires the selection of a biomarker associate with clinical efficacy in patients with AR who are treated with SLIT. The present study sought to examine objective biomarkers used for assessing the clinical efficacy of SLIT. METHODS The authors examined the effects of 1 year of SLIT treatment with house dust mites (HDMs) using peripheral blood mononuclear cells (PBMCs) and serum from patients with AR. The prevalences of follicular regulatory T (Tfr), type 2 follicular helper T (Tfh2), type 2 helper T (Th2), conventional regulatory T (Treg), and type 1 regulatory T (Tr1) cells were examined by flow cytometry. Serum concentrations of HDM-specific IgA, IgE, and IgG4 antibodies, and HDM-induced production of interleukin (IL) 5 and IL-10 from cultured PBMCs were evaluated by enzyme-linked immunosorbent assay. RESULTS Following 1 year of SLIT, the prevalences of Tfr, conventional Treg, and Tr1 cells were significantly increased, whereas that of Th2 cells and Tfh2 cells were significantly decreased; the serum concentration of HDM-specific IgG4 was significantly increased; and HDM-induced production of IL-5 from PBMCs was significantly decreased, while that of IL-10 was significantly increased. The increase in the prevalence of Tfr cells after SLIT correlated positively with the improvement of clinical symptom scores. CONCLUSION An increase in Tfr cells may play an important role in SLIT, and may be a useful indicator for the clinical efficacy of SLIT.

Abstract
Both subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT) are effective clinically against allergic rhinitis and allergic asthma, and modify the underlying immunologic abnormalities. Despite this, many patients who could benefit from receiving SCIT and SLIT do not because of concerns about safety and the inconvenience in receiving SCIT, and the long duration of treatment with both, 3-4 years being required for lasting benefit. Attempts to improve the efficacy and safety, and to shorten the course of allergen immunotherapy have taken many approaches. Some approaches have generated great enthusiasm, only to fail in larger trials and be discarded. Other approaches show some promise but perhaps not enough to achieve regulatory approval. Those approaches that seem to have the best chance of becoming available in the next few years include the following: intralymphatic and epicutaneous immunotherapy, vitamin D in patients with insufficient serum 25 hydroxy vitamin D, probiotics, and allergoids, but all require further studies before being ready for nonexperimental use or, where necessary, for regulatory approval.

Dropouts From Sublingual Immunotherapy and the Transition to Subcutaneous Immunotherapy in House Dust Mite-Sensitized Allergic Rhinitis Patients. FRONTIERS IN ALLERGY 2022; 2:810133. [PMID: 35386972 PMCID: PMC8974757 DOI: 10.3389/falgy.2021.810133] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2021] [Accepted: 11/30/2021] [Indexed: 12/05/2022] Open
Abstract
Purpose: Both subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT) are effective in reducing symptoms and medication scores and inducing long-term efficacy in patients with allergic rhinitis (AR). However, SLIT has been associated with poor patient adherence. This study investigates the factors impacting dropout rates from SLIT in house dust mite (HDM)-sensitized AR patients. Methods: A retrospective study was performed to analyze dropout rates and reasons in AR patients receiving Dermatophagoides farinae (Der f) SLIT with a follow-up period of 2 years. Results: A total of 719 HDM-sensitized AR patients received Der f-SLIT. Dropout rates increased with time and most occurred after 1 year of SLIT. By month 24, 654 (91%) patients had discontinued SLIT. The dropout rates by month 24 were 100, 90.1, and 91.1% in children <5 years old, children aged 5–18 years old, and adults ≥ 18 years old, respectively. Combination with allergic asthma and mono- or multi-sensitization to other aeroallergens did not affect the dropout rates. The most common self-reported reasons for dropouts were refusal of continuation, dissatisfaction with the efficacy, transition to SCIT, and adverse effects. Refusal of continuation increased with age, whereas transition to SCIT decreased with age. Ninety-seven cases transitioned from SLIT to SCIT, and the transition rates increased with time. Comorbid allergic asthma did not affect the transition rates. However, multi-sensitization was associated with a slightly higher rate of transition to SCIT. The most common reason for the transition was dissatisfaction with the efficacy (54.6%), which was only reported by patients older than 5 years. For children who began SLIT at younger than 5 years old, the most common reason (81.2%) for transition was age reaching 5 years. Conclusions: HDM-SLIT has a very high dropout rate, which is mainly due to refusal of continuation and dissatisfaction with the efficacy. Transitioning from SLIT to SCIT may help keep these patients on AIT and thus increase adherence and long-term efficacy.

Suppression function against environmental dust exposure after Dermatophagoides pteronyssinus immunotherapy is associated with production of specific and cross-reactive immunoglobulin G4. Clin Exp Allergy 2021; 52:878-887. [PMID: 34962673 DOI: 10.1111/cea.14088] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Revised: 12/06/2021] [Accepted: 12/25/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Whether Dermatophagoides pteronyssinus (Der-p) allergen immunotherapy (AIT) can induce Dermatophagoides farina (Der-f) specific immunoglobulin (sIg) G4 production and tolerance to environmental allergens has not been fully investigated. OBJECTIVE We aimed to determine serum Der-p-sIgG4 and Der-f-sIgG4 levels in asthma and/or rhinitis patients undergoing Der-p AIT and their ability to reduce immune responses triggered by indoor-dust extracts. METHODS We performed a real-world prospective trial and enrolled patients with allergic rhinitis and/or asthma in Guangzhou, China. These patients received either Der-p AIT (SCIT group) or routine medications (non-SCIT group) for 156 weeks. Clinical outcomes were assessed by the combined symptom medication score (SMS) and FEV1 % changes. House dust samples were collected to analyze allergen levels. Serum levels of Der-p-sIgG4 and Der-f-sIgG4, serum inhibitory capacity against Der-p, Der-f, and indoor dust extract by sIgE-facilitated allergen binding to B cells (IgE-FAB), and serum blocking indoor dust extract-induced basophil activation inhibition assays (BATI) in peripheral blood monocytes were carried out at weeks 0, 4, 12, 16, 52, 104, and 156 after the initiations of the treatments. RESULTS Our study enrolled a total of 60 participants, with 30 patients in each group. Patients in the SCIT group had significantly improved SMS when compared with the baseline and the patients in the non-SCIT group. Median levels of Der-p 1 and Der-f 1 in indoor dust extract were 1.86 μg/g and 4.74 μg/g, respectively. Serum Der-p-sIgG4 and Der-f-IgG4 levels in SCIT patients showed a significant increase from week 12 to week 156. Serum in these SCIT patients could significantly block Der-p, Der-f, and indoor dust extract formation of allergen-sIgE complex and reduced the threshold of IgE-FAB from 16 weeks after the initiation of the treatment. The capacity to inhibit Der-p, Der-f, and indoor dust extract BATI was observed in SCIT serum after 12 weeks. Der-p-sIgG4 and Der-f-sIgG4 had a significant correlation with IgE-FAB and BATI in SCIT patients at all time points. CONCLUSION Single Der-p immunotherapy induced both Der-p-sIgG4 and Der-f-sIgG4 production, which might cross-reactively induce tolerance against environmental allergen exposure in patients with asthma and/or rhinitis.

Abstract
Objective Compare the cost-effectiveness of subcutaneous immunotherapy (SCIT) and aqueous sublingual immunotherapy (SLIT) as treatment modalities for adult patients with allergic rhinitis and conjunctivitis who undergo testing and qualify for allergen immunotherapy (AIT). Methods A systematic review was performed to identify key statistics for analysis, including the compliance and efficacy rates for each treatment. The body of literature on this topic is highly heterogeneous, so ranges were obtained and assumptions stated clearly where they were made. Charges were derived from average commercial payor charges from a single hospital institution. A hypothetical 100 patients are examined for the study. Results A cost-effectiveness sensitivity analysis was then performed using a decision tree model to compare the modalities. A sensitivity and threshold analysis was then performed to assess the strength of recommendations after identifying results at baseline. Discussion Assuming an 80% compliance rate with allergen immunotherapy and an estimated efficacy (assumed to be clinically significant improvement in symptoms) of 70% for SLIT and 80% for SCIT, at the 12-month mark, the baseline total cost to the payor of SLIT per successful treatment outcome is $1196 while the charge of SCIT per successful treatment outcome is $2691. Our analysis favors SLIT as the more cost-effective modality per successful outcome. Implications for Practice When compared to SCIT, SLIT is economically favorable and should be considered the financially conscious option for patients with >40% adherence to therapy.

Abstract
BACKGROUND Intranasal corticosteroids (INCS), oral antihistamines (POAH), and allergen-specific immunotherapy (ASIT) are widely used in the treatment of allergic rhinitis (AR); however, appraisal of treatment effect has been heterogenous, and few studies have interpreted these outcomes in context with measures of nasal airflow. OBJECTIVE To provide a systematic review and meta-analysis of randomized placebo-controlled trials for common therapy classes for AR to assess standardized treatment effect on validated patient-reported outcomes and physiologic measures of airflow. METHODS A systematic search was performed in PubMed, Scopus, OVID, and Cochrane library databases to identify randomized controlled trials meeting inclusion criteria. Treatment effects of INCS, POAH, and ASIT on total nasal symptom score (TNSS), visual analog scale (VAS), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), and peak nasal inspiratory flow (PNIF) were analyzed by meta-analysis. RESULTS Twenty-two studies with 4673 AR patients were identified, with 5 INCS, 8 POAH, and 9 ASIT trials. INCS improved TNSS (mean difference [MD] 0.90; P = .002) and PNIF (MD 13.31 L/min [P = .0007]. POAH improved quality of life assessed by RQLQ [MD 0.36; P < .001], but no improvement was found in PNIF. ASIT improved RQLQ [MD 0.65; P < .001], with a trend toward improvement in TNSS. CONCLUSION Overall, INCS resulted in a clinically and statistically meaningful improvement in symptom scores and physiologic measures in AR. POAH and ASIT both improved symptom scores and quality of life, but their impacts upon nasal airflow are uncertain. There is a lack of studies assessing the effect of INCS on quality of life and the effect of POAH on symptom severity, particularly for mild AR. Future studies should assess the effect of treatment for each of these patient-reported measures.

Abstract
Food allergy is a serious health problem affecting more than 10% of the human population worldwide. Medical treatments for food allergy remain limited because immune therapy is risky and costly, and anti-allergic drugs have many harmful side effects and can cause drug dependence. In this paper, we review natural bioactive substances capable of alleviating food allergy. The sources of the anti-allergic substances reviewed include plants, animals, and microbes, and the types of substances include polysaccharides, oligosaccharides, polyphenols, phycocyanin, polyunsaturated fatty acids, flavonoids, terpenoids, quinones, alkaloids, phenylpropanoids, and probiotics. We describe five mechanisms involved in anti-allergic activities, including binding with epitopes located in allergens, affecting the gut microbiota, influencing intestinal epithelial cells, altering antigen presentation and T cell differentiation, and inhibiting the degranulation of effector cells. In the discussion, we present the limitations of existing researches as well as promising advances in the development of anti-allergic foods and/or immunomodulating food ingredients that can effectively prevent or alleviate food allergy. This review provides a reference for further research on anti-allergic materials and their hyposensitizing mechanisms.

Abstract
PURPOSE OF REVIEW Allergen immunotherapy has been used for over 100 years in the treatment of allergic rhinitis. With two major options for administering this disease-modifying therapy, SCIT, and SLIT, what is our current understanding of the efficacy and safety of each one? How do we determine who is the appropriate candidate for each one in the real world? RECENT FINDINGS SCIT and SLIT show significant improvement in clinical symptoms and need for medication in the treatment of allergic rhinitis. In recent meta-analyses, there is no significant difference in the efficacy between the two treatments, but SLIT has more local side effects though less systemic ones. Shared decision-making should be instituted to determine which treatment should be started in a patient with allergic rhinitis. This review provides up-to-date information on the efficacy and safety of SCIT vs SLIT in the care of children and adults with allergic rhinitis in the real world and the role of shared decision-making in the use of these modalities.

Abstract
It is unclear if allergen immunotherapy (AIT) can reduce allergy effector cell activation. We evaluated the basophil response during Dermatophagoides pteronyssinus (Der p) subcutaneous immunotherapy (SCIT) and its relationship to allergen-specific immunoglobulin G4 (sIgG4) in allergic rhinitis and/or asthma patients. The study included 55 subjects, of which 35 cases received Der p SCIT and 20 controls received standard medications. Symptom and medication scores (SMSs), sIgG4 levels, specific immunoglobulin E (sIgE) levels, allergen-induced basophil activation tests (BATs) in whole blood, and BAT inhibition assays in serum were determined at weeks 0, 4, 12, 16, 52, and 104 of SCIT. Levels of Der p sIgG4 in SCIT patients significantly increased after 12 weeks of treatment compared to week 0. Serum obtained from SCIT patients significantly inhibited basophil activation after 12 weeks of treatment. Removal of immunoglobulin G4 (IgG4) antibodies at week 104 reduced the ability of serum to block basophil activation. An increase of Der p sIgG4 rather than reduction of Der p sIgE correlated with the reduction of basophil activation during SCIT. The sIgG4 antibodies may compete with sIgE binding to allergens to form an immunoglobulin E (IgE)-allergen complex. SCIT reduced the sensitivity of allergen-triggered basophil activation in Der p allergic rhinitis and/or asthma patients through induction of sIgG4.

Abstract
BACKGROUND The burden of allergic diseases is of particular relevance for the economy and the social welfare and health insurance framework. Allergic rhinitis (AR) has a life-time prevalence of approximately 30% and is one of the most common chronic diseases with considerable socioeconomic impact thus leading to substantial direct, indirect and intangible costs. This article explores the common hypothesis that allergen-specific immunotherapy (ASIT) saves national economic expenses in the long term in comparison to other standard symptomatic treatment or no therapy. METHODS We conducted a selective search and analysis of the literature in PubMed and Medline including otherwise listed publications in German. Using a predefined model and data extrapolation over 9 years for data from different sources and short-term clinical studies we further discuss the problems and difficulties in analyzing heterogeneous datasets. RESULTS Using a health-economic model with currently available and accepted variables ASIT proves to be cost-effective in comparison to symptomatic treatment in allergic rhinitis; however, numerous parameters from other models have to be controlled, such as adherence to therapy and therapy discontinuation, heterogeneous costs for different treatment modalities, effect sizes with respect to symptoms including cross-influences with symptomatic rescue medication, duration of efficacy after treatment discontinuation and asthma protection. DISCUSSION The personal appraisal of the authors demonstrates not only the current knowledge but also the problems in health economical evaluation of ASIT in allergic diseases.

Mind the gaps: Clinical trial concepts to address unanswered questions in aeroallergen immunotherapy-An NIAID/AHRQ Workshop. J Allergy Clin Immunol 2019; 143:1711-1726. [PMID: 30731123 DOI: 10.1016/j.jaci.2019.01.032] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2018] [Revised: 01/08/2019] [Accepted: 01/22/2019] [Indexed: 11/21/2022]
Abstract
The Agency for Healthcare Research and Quality and the National Institute of Allergy and Infectious Diseases organized a workshop to develop trial concepts that could improve the use and effectiveness of aeroallergen immunotherapy (AAIT). Expert groups were formed to accomplish the following tasks: (1) propose a study design to compare the effectiveness and safety of subcutaneous versus sublingual AAIT; (2) propose a study design to compare the effectiveness and safety of AAIT by using 1 or a few allergens versus all or most allergens to which a patient is sensitized; (3) propose a study design to determine whether AAIT can alter the progression of childhood allergic airways disease; and (4) propose a study design to determine the optimal dose and duration of AAIT to achieve maximal effectiveness with acceptable safety. Study designs were presented by the workgroups, extensively discussed at the workshop, and revised for this report. The proposed trials would be of long duration and require large highly characterized patient populations. Scientific caveats and feasibility matters are discussed. These concepts are intended to help the development of clinical trials that can address some of the major questions related to the practice of AAIT for the management and prevention of allergic airways disease.

Int Forum Allergy Rhinol 2019; 9:615-623. [PMID: 31173675 DOI: 10.1002/alr.22308] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2018] [Revised: 01/11/2019] [Accepted: 01/15/2019] [Indexed: 11/08/2022]
Abstract
BACKGROUND Sublingual immunotherapy (SLIT) is safe and effective but compliance is problematic. In this study we evaluated dropout and compliance among adults (≥20 years of age) and adolescents (<20 years of age) for Japanese cedar pollen extract (JCPE), an aqueous SLIT approved in 2014 in Japan. METHODS Administrative claims data on 1236 Japanese patients, 846 adults (mean age, 43.0 years; 41.8% female) and 249 adolescents (mean age, 14.1 years; 36.6% female), with a JCPE prescription between October 2014 and June 2016 were reviewed. Adults and adolescents were divided according to the year they started SLIT (1- and 2-year cohorts) to calculate dropout and compliance and identify associated factors using multivariate Cox and linear regression models. RESULTS In 1- and 2-year adult cohorts, dropout rates were 13.5% and 22.1% and compliance rates were 92.8% and 88.8%, respectively. Adolescents had higher dropout and lower compliance. Patients 40-59 years of age had a lower dropout risk than patients 20-29 years of age. Dropout hazard ratios (95% confidence interval) in 1- and 2-year cohorts were 0.26 (0.12-0.58) and 0.40 (0.17-0.93) in patients 40-49 years of age and 0.32 (0.14-0.75) and 0.35 (0.13-0.92) in patients 50-59 years of age, respectively. Younger age contributed to lower compliance in 1- and 2-year adult cohorts (p = 0.001 and p = 0.02, respectively). Systemic steroidal medication history and male gender were positively associated with compliance in adults but not in adolescents. CONCLUSION High dropout rate was associated with younger generations. Compliance in adults, but not in adolescents, was associated with age, systemic steroidal medication history, and gender.

Subcutaneous immunotherapy suppresses Th2 inflammation and induces neutralizing antibodies, but sublingual immunotherapy suppresses airway hyperresponsiveness in grass pollen mouse models for allergic asthma. Clin Exp Allergy 2018; 48:1035-1049. [PMID: 29752757 DOI: 10.1111/cea.13169] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2017] [Revised: 03/30/2018] [Accepted: 05/01/2018] [Indexed: 01/05/2023]
Abstract
BACKGROUND Both subcutaneous and sublingual allergen immunotherapy (SCIT and SLIT) have been shown to effectively suppress allergic manifestations upon allergen exposure, providing long-term relief from symptoms in allergic disorders including allergic asthma. Clinical studies directly comparing SCIT and SLIT report a different kinetics and magnitude of immunological changes induced during treatment. Comparative studies into the mechanisms underlying immune suppression in SCIT and SLIT are lacking. OBJECTIVE We aimed to establish an experimental model for grass pollen (GP) SCIT and SLIT that would allow a head-to-head comparison of the two treatments. METHODS BALB/c mice were sensitized with GP extract, followed by SCIT and SLIT treatments with various GP dosages. Subsequently, we challenged mice with GP and measured airway responsiveness (AHR), GP-specific immunoglobulins, ear swelling tests (EST), eosinophilic inflammation in bronchoalveolar lavage fluid (BALF), and T cell cytokine release after restimulation of lung cells (IL-5, IL-10, and IL-13). RESULTS We find that SLIT treatment was able to suppress allergen-induced AHR, while allergic inflammation was not effectively suppressed even at the highest GP dose in this model. In contrast, SCIT treatment induced higher levels of GP-specific IgG1, while SLIT was superior in inducing a GP-specific IgG2a response, which was associated with increased Th1 activity in lung tissue after SLIT, but not SCIT treatment. Interestingly, SCIT was able to suppress Th2-type cytokine production in lung cell suspensions, while SLIT failed to do so. CONCLUSIONS AND CLINICAL RELEVANCE In conclusion, GP-SCIT suppresses Th2 inflammation and induced neutralizing antibodies, while GP-SLIT suppresses the clinically relevant lung function parameters in an asthma mouse model, indicating that the two application routes depend on partially divergent mechanisms of tolerance induction. Interestingly, these data mirror observations in clinical studies, underscoring the translational value of these mouse models.

Cost-effectiveness of grass pollen subcutaneous immunotherapy (SCIT) compared to sublingual immunotherapy (SLIT) and symptomatic treatment in Austria, Spain, and Switzerland.

Abstract
BACKGROUND While specific immunotherapy (SIT) has been proven to be cost-effective for the treatment of allergic rhinitis compared to symptomatic treatment, there is a lack of European studies in which sublingual (SLIT) and subcutaneous (SCIT) immunotherapy were compared. The present analysis is focused on the cost-effectiveness of SCIT compared to SLIT and symptomatic treatment of grass pollen allergy in Austria, Spain, and Switzerland. It will address specific properties of the underlying healthcare systems. METHODS The investigation is based on a previously published health economic model calculation. This was designed as a Markov model with pre-defined health stages and a duration of 9 years covering specific preparations for SCIT (Allergovit) and SLIT (Oralair). The effectiveness was assessed as symptom-score based quality-adjusted life years (QALYs). Additionally, total cost has been determined as well as the cost-effectiveness of SCIT. The robustness of model results was proved in further sensitivity analyses. RESULTS With regard to the effectiveness of both SCIT and SLIT, preparations were dominant compared to pharmacological symptomatic therapy. Both strategies were associated with additional cost, but, combined with the results on effectiveness, both have to be regarded as cost-effective. A direct comparison of the SCIT (Allergovit) and SLIT (Oralair) showed lower total costs of SCIT vs SLIT for Austria, Spain, and Switzerland (€1,368 vs €2,012, €2,229 vs €2,547, and €1,901 vs €2,220) and superior effectiveness (SCIT =8.02 QALYs; SLIT =7.98 QALYs; and symptomatic therapy =7.90 QALYs). CONCLUSION In patients with allergic rhinitis, SIT offers cost-effective treatment options compared to symptomatic treatment. When comparing SCIT (Allergovit) and SLIT (Oralair), SCIT was dominant in terms of QALYs as well as costs, in particular due to a slightly higher patient compliance and lower drug costs.

Abstract
Although traditional pharmacological approaches improve outcomes in disease management for allergic asthma, these fail to modify the underlying immune responses. Allergen immunotherapy remains the only etiological therapy for the treatment of respiratory allergies for which clinical efficacy has been demonstrated through several well-controlled studies. In this review, we examine evidence from the past 5 years regarding the impact of allergen immunotherapy on allergic asthma to inform practitioners and stimulate further discussion and research.

Abstract
BACKGROUND AND OBJECTIVES In Sweden, approximately 6% of children and 10% of adults suffer from house dust mite (HDM) allergy with symptoms of allergic rhinitis and allergic asthma. Treatment is aimed at reducing HDM exposure and to control the symptoms of allergic rhinitis and allergic asthma by symptom-relieving pharmacotherapy. This pharmacotherapy is often effective, but some patients remain inadequately controlled. For these patients, allergy immunotherapy (AIT, subcutaneous or sublingual) with repeated administration of HDM allergen should be considered. The objective of this study was to compare the costs for sublingual AIT (SLIT; SQ® SLIT-tablet) to the costs for subcutaneous AIT (SCIT; SQ® SCIT) for the treatment of HDM allergy in a cost-minimisation analysis (CMA). METHODS The CMA included resources (and costs) for treatment, healthcare visits, travelling and lost productivity. Resource use based on Swedish clinical treatment practice and costs were obtained from medical price lists. Analyses were conducted from the societal, as well as healthcare perspective, by use of a time horizon of 3 years. RESULTS The results show that SQ® SLIT-tablet is a cost-saving treatment as compared to SQ® SCIT for the treatment of HDM allergy (€6800 over 3 years). The results are mainly driven by the cost of healthcare visits and the frequency of SCIT administrations. CONCLUSION In conclusion, cost-savings of €6800 over 3 years are expected from treating HDM allergy with SQ® SLIT-tablet as compared to SQ® SCIT, including costs for treatment, healthcare visits, travelling and lost productivity. The reduced number of healthcare visits compensates for higher medication costs.

Abstract
PURPOSE The tree pollen sublingual immunotherapy (SLIT)-tablet (ALK, Denmark) is being developed for the treatment of tree pollen induced allergic rhinitis with or without conjunctivitis. The objective of this Phase I trial was to investigate the tolerability and acceptable dose range of the SQ tree SLIT-tablet in adults with allergic rhinoconjunctivitis. METHODS The trial was a randomized, double-blind, placebo-controlled, dose escalation Phase I trial that included 70 adults (aged 19-61 years) with birch pollen-induced rhinoconjunctivitis with or without mild to moderate asthma. The trial included 6 different dosage groups that were randomized 3:1 to active treatment or placebo once daily for 28 days. Adverse events (AEs) were coded in the Medical Dictionary for Regulatory Activities by medically qualified personnel. Immunologic assessments included IgE and IgE-blocking factor. FINDINGS Most (96%) reported AEs were mild, and only 5 severe events (0.2%) were reported. The most frequently reported investigational medicinal product-related AEs were oral pruritus, ear pruritus, mouth edema, sensation of foreign body, throat irritation, pharyngolaryngeal pain, dry throat, tongue blistering, eye pruritus, and headache. The trial included doses ranging from 1 to 24 development units (DU), and the mean number of investigational medicinal product-related AEs per participant was highest in the 24 DU group. The 12 and 24 DU doses induced statistically significant changes from baseline compared with placebo in birch specific IgE and IgE-blocking factor. IMPLICATIONS The trial found that doses up to 12 DU of the SQ tree SLIT tablet have a tolerability profile suitable for at-home administration. An immunomodulatory effect was found for all doses included in the trial, and doses up to 12 DU were thus chosen for further clinical development of the SQ tree SLIT tablet. EudraCT identifier: 2007-003234-42.

Abstract
Allergen-specific immunotherapy is the only causal treatment for allergic diseases. However, the efficacy of immunotherapy may vary around the world due to differences in climate, the nature of aero-allergens and their distribution. The aim of this study was to describe the effects of subcutaneous immunotherapy (SCIT) in Korean adults with allergic asthma (AA). As a retrospective cohort study, we reviewed medical records for 627 patients with AA in Korea who were sensitized to house dust mite (HDM) and/or pollens and who underwent SCIT with aluminum hydroxide adsorbed allergen extract from 2000 to 2012. Rates of remission, defined as no further requirement of maintenance medication, over time were determined by means of life tables and extension of survival analysis. Herein, 627 asthmatic patients achieved remission within a mean of 4.7 ± 0.2 years. The cumulative incidence rates of remission from AA were 86.9% upon treatment with SCIT. Baseline forced expiratory volume in the first second (FEV1) ≥ 80% (hazard ratio [HR], 3.10; 95% confidence interval [CI], 1.79-5.39; P < 0.001), and maintenance of immunotherapy for more than 3 years (HR, 1.82; 95% CI, 1.21-2.72; P = 0.004) were significant predictors of asthma remission during SCIT. In 284 patients on SCIT with HDM alone, initial specific immunoglobulin E (IgE) levels to Dermatophagoides pteronyssinus and Dermatophagoides farinae did not show significant difference between remission and non-remission group after adjusting demographic variables. In conclusion, SCIT was effective and safe treatment modality for patients with AA. Initial FEV1 ≥ 80% and immunotherapy more than 3 years were found to be associated with favorable clinical responses to SCIT.

Abstract
It has always been controversial whether a single allergen performs better than multiple allergens in polysensitized patients during the allergen-specific immunotherapy. This study aimed to examine the clinical efficacy of single-allergen sublingual immunotherapy (SLIT) versus multi-allergen subcutaneous immunotherapy (SCIT) and to discover the change of the biomarker IL-4 after 1-year immunotherapy in polysensitized children aged 6-13 years with allergic rhinitis (AR) induced by house dust mites (HDMs). The AR polysensitized children (n=78) were randomly divided into two groups: SLIT group and SCIT group. Patients in the SLIT group sublingually received a single HDM extract and those in the SCIT group were subcutaneously given multiple-allergen extracts (HDM in combination with other clinically relevant allergen extracts). Before and 1 year after the allergen-specific immunotherapy (ASIT), the total nasal symptom scores (TNSS), total medication scores (TMS) and IL-4 levels in peripheral blood mononuclear cells (PBMCs) were compared respectively between the two groups. The results showed that the TNSS were greatly improved, and the TMS and IL-4 levels were significantly decreased after 1-year ASIT in both groups (SLIT group: P<0.001; SCIT group: P<0.001). There were no significant differences in any outcome measures between the two groups (for TNSS: P>0.05; for TMS: P>0.05; for IL-4 levels: P>0.05). It was concluded that the clinical efficacy of single-allergen SLIT is comparable with that of multi-allergen SCIT in 6-13-year-old children with HDM-induced AR.

Abstract
Allergic diseases are highly prevalent worldwide and affect all age groups, contributing to a high personal and socioeconomic burden. Treatment with an “allergy vaccine” or allergen immunotherapy aims to provide long-lasting benefits by inducing unresponsiveness to the relevant antigen. The consequences of the therapy are considered disease modifying and range from dampening of the immediate immune responses to the reduction of secondary tissue remodeling. Furthermore, allergen immunotherapy interventions have a potential to slow or cease the development of additional allergic manifestations with a long-term overall effect on morbidity and quality of life. Here, we review proposed mechanisms underlying the therapeutic effects of immunotherapy for allergic diseases. Further, we discuss both standard and novel approaches and possible future directions in the development of allergen immunotherapy.

Abstract
Current allergen-specific immunotherapy (AIT) for pollinosis requires long-term treatment with potentially severe side effects. Therefore, development of an AIT that is safe and more convenient with a shorter regimen is needed. This prospective, double-blind, placebo-controlled trial randomized 55 participants with Japanese cedar pollinosis (JCP) to active or placebo groups to test the safety and efficacy of short-term oral immunotherapy (OIT) with Cry j 1-galactomannan conjugate for JCP. Mean symptom-medication score as the primary outcome in the active group improved 27.8% relative to the placebo group during the entire pollen season. As the secondary outcomes, mean medication score in active group improved significantly, by 56.2%, compared with placebo during the entire pollen season. Mean total symptom score was similar between active and placebo groups during the entire pollen season. There were no severe treatment-emergent adverse events in the active and placebo groups. Therefore short-term OIT with Cry j 1-galactomannan conjugate is safe, and effective for reducing the amount of medication use for JCP.

Abstract
Since it was introduced by Noon in 1911, allergen-specific immunotherapy or desensitization has been widely prescribed in the management of allergic diseases. Aimed at the etiology, it represents the only effective treatment for allergy. The basic mechanisms of immunotherapy are becoming better understood and allow us to improve this technique in the future. The sublingual immunotherapy as an alternative to subcutaneous route has been widely studied. Several clinical trials confirmed that sublingual immunotherapy is efficient in reducing allergic respiratory symptoms. The sublingual immunotherapy reduces the risk of developing serious side effects due to desensitization. We performed a literature review in order to remind the mechanisms of action and to demonstrate efficacy and tolerability of the sublingual immunotherapy in the treatment of allergic rhinoconjunctivitis and asthma and its impact on the quality of life.

Abstract
BACKGROUND Allergen-specific immunotherapy is the only curative treatment for type I allergy. It can be administered subcutaneously (SCIT) or sublingually (SLIT). The clinical efficacy of these two treatment modalities appears to be similar, but potential differences in the immunological mechanisms involved have not been fully explored. OBJECTIVE To compare changes in the allergen-specific T cell response induced by subcutaneous vs. sublingual administration of allergen-specific immunotherapy (AIT). METHODS Grass pollen-allergic patients were randomized into groups receiving either SCIT injections or SLIT tablets or neither. PBMCs were tested for Timothy grass (TG)-specific cytokine production by ELISPOT after in vitro expansion with TG-peptide pools. Phenotypic characterization of cytokine-producing cells was performed by FACS. RESULTS In the SCIT group, decreased IL-5 production was observed starting 10 months after treatment commenced. At 24 months, T cell responses showed IL-5 levels significantly below the before-treatment baseline. No significant reduction of IL-5 was observed in the SLIT or untreated group. However, a significant transient increase in IL-10 production after 10 months of treatment compared to baseline was detected in both treatment groups. FACS analysis revealed that IL-10 production was associated with CD4(+) T cells that also produced IFNγ and therefore may be associated with an IL-10-secreting type 1 cell phenotype. CONCLUSION AND CLINICAL RELEVANCE The most dominant immunological changes on a cellular level were a decrease in IL-5 in the SCIT group and a significant, transient increase of IL-10 observed after 10 months of treatment in both treated groups. The distinct routes of AIT administration may induce different immunomodulatory mechanisms at the cellular level.

Abstract
Background Whereas specific immunotherapy (SIT) has already been shown to be cost-effective in the treatment of allergic rhinitis compared with symptomatic treatment, only a small number of investigations have compared sublingual (SLIT) and subcutaneous (SCIT) immunotherapeutic approaches. This analysis discusses the cost-effectiveness of SCIT compared with SLIT and a symptomatic treatment modality. At the same time, particular attention is paid to preparation-specific characteristics. Methods The investigation is based on a previously published health economic model calculation. A Markov model, with predefined disease stages and a time period of 9 years, formed the basis of the analysis. The data on specific SCIT (Allergovit®) and SLIT (Oralair®) preparations required for the calculation were adjusted for the present analysis. Quality-adjusted life years (QALYs) based on symptom scores were calculated as the endpoint for effectiveness. Furthermore, the total costs and cost effectiveness of SCIT were determined. Model uncertainties were estimated by means of additional sensitivity analyses. Results With regard to effectiveness, both the SCIT and SLIT preparations proved superior compared to symptomatic treatment. Although more expensive, SIT seem to be cost-effective. A direct comparison of SCIT (Allergovit®) and SLIT (Oralair®) showed lower total costs for SCIT treatment over the study period (SCIT 1159 € versus SLIT 1322 €) and improved effectiveness (SCIT 7.112 QALYs versus SLIT 7.060 QALYs). Discussion SIT represents a cost-effective treatment option for patients with allergic rhinitis compared with symptomatic treatment. The comparison of SCIT (Allergovit®) and SLIT (Oralair®) showed SCIT to be predominant and cost-effective, due in particular to somewhat greater patient compliance and lower drug costs. It also became evident that, as far as possible, product-specific model variables are required for an economic evaluation of SIT treatment.

Abstract
Subcutaneous immunotherapy and sublingual immunotherapy are effective for allergic rhinitis and allergic asthma and with some support for use in selected patients with atopic dermatitis. The sequence of immunologic responses is the same, irrespective of the route of administration, and similar disease modification has been demonstrated. However, there are differences between the two approaches. The most important is the greatly reduced likelihood of sublingual immunotherapy producing systemic reactions. There are major drawbacks for sublingual immunotherapy in regard to dosing. Finally, there is the question of relative clinical efficacy, with the currently available data favoring subcutaneous immunotherapy.

Abstract
Allergies comprise a set of highly prevalent diseases. When allergic processes are not controlled, they can endanger patients' health and lives, and have an important economic and social impact. The aim of this paper is to present a practical consensus of the scientific evidence on the use of immunotherapy in allergic diseases. A collaborative review made by various institutes and universities in Colombia was carried out upon request of the Asociación Colombiana de Alergia, Asma e Imunología, led by general practitioners, allergists, immunologists, internists and paediatricians with experience in the field of allergies. As a result, based on current national and international scientific evidence, we describe in detail what immunotherapy is about, its indications, contraindications and its economic and health benefits. Conclusions show immunotherapy as a clinically effective and safe treatment, which can substantially reduce the cost of the overall treatment of allergic patients.

Abstract
Objectives Currently, patients with persistent moderate-to-severe house dust mite (HDM) allergic rhinitis despite use of symptom-relieving medication can be offered subcutaneously administered allergy immunotherapy (SQ SCIT; Alutard SQ) as standard care of treatment in Denmark. Recently, a HDM sublingually administered allergy immunotherapy tablet (SQ SLIT-tablet; ACARIZAX) has been developed for at-home treatment. The purpose of this analysis is to compare the costs related to treatment and administration of SQ SLIT-tablet and SQ SCIT. Methods Assuming equal efficacy between ther SQ SLIT-tablet and SQ SCIT, the cost-minimization analysis was the most appropriate for the comparison. According to guidelines and Summary of Product Characteristics, the treatment duration of SQ SLIT-tablet is 3 years and 3-5 years for SQ SCIT. The courses of treatment vary among patients and, therefore, the costs of treatment have been calculated for an average patient with HDM respiratory allergic disease (RAD) receiving either SQ SLIT-tablet or SQ SCIT. All costs associated with allergy immunotherapy were collected, i.e., cost of medication, administration and treatment setting, and discounted according to Danish guidelines. Comprehensive univariate sensitivity analyses were carried out. Results The treatment costs for an average patient with HDM RAD are €3094 for SQ SLIT-tablet and €3799 for SQ SCIT; however, when adding indirect costs to the calculations the total costs of the treatments are €3697 and €6717 for SQ SLIT-tablet and SQ SCIT, respectively. Therefore, if 2500 patients with HDM RAD were treated with SQ SLIT-tablet instead of SQ SCIT, it would elicit a saving to the healthcare system of ∼€1.8 million. The conclusion was robust to any changes in the sensitivity analysis. Conclusion With regards to the cost of treating Danish patients with HDM RAD, it is clearly cost-saving to treat patients with SQ SLIT-tablet compared to SQ SCIT.

Abstract
Conditions such as chronic rhinitis, urticaria, angioedema, and asthma are frequently seen in clinics and hospitals, and there are a core group of medications that are often used to treat these conditions. Knowing the indications, optimal dosing, and side-effect profile of these medications can improve outcomes. Chronic rhinitis due to various causes is one of the most common reasons for primary care physician visits. Knowing the indications for use, forms of administration, and side-effect profiles of these medications can help improve patient outcomes in these common conditions. This review focuses on the medications used to treat these conditions.

Abstract
BACKGROUND The contribution of antigen-specific TH cells in peripheral blood to immunologic mechanisms underlying sublingual immunotherapy (SLIT) remains unclear, partly because of the lack of a standardized method for the analysis of this rare lymphocyte subset. OBJECTIVE To clarify the role of antigen-specific TH cells during SLIT using a sensitive method analyzing activation marker CD154-positive TH cells with multicolor flow cytometry. METHODS We assessed antigen-specific TH cells using multicolor flow cytometry based on the expression of the activation marker CD154 and intracellular cytokines in patients with Japanese cedar pollinosis receiving SLIT at baseline and during the first pollen season after the initiation of SLIT. RESULTS A total of 18 patients between 12 and 44 years of age were enrolled in the present study. Of these, 8 patients received SLIT (SLIT group) and 10 patients received symptomatic treatment only (control group). Although seasonal pollen exposure significantly increased the number of Japanese cedar-specific interleukin 5- and interleukin 4-producing TH cells in the control group (P < .01 for both), SLIT ameliorated this increase in the SLIT group (P = .64 and P = .84, respectively). CONCLUSION The present study indicates that allergen-specific TH2 cells in peripheral blood are involved in mechanisms underlying SLIT. The analysis of antigen-specific TH cells using multicolor flow cytometry based on the expression of the activation marker CD154 represents a sensitive and relatively simple, standardized method for monitoring peripheral antigen-specific TH cells during allergen-specific immunotherapy.

Abstract
INTRODUCTION Allergic rhinitis is a worldwide health problem, currently affecting up to 40% of the general population, and characterized by the following symptoms in a variable degree of severity and duration: nasal congestion/obstruction, rhinorrhea, itchy nose and/or eyes, and/or sneezing. General symptoms like fatigue, reduced quality of sleep, impaired concentration and reduced productivity, if left untreated, may significantly affect quality of life. In addition, of being associated to various comorbidities, allergic rhinitis is also an independent risk factor for the development and worsening of asthma. Perennial allergic rhinitis is caused by allergens present around the year. AREAS COVERED Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines currently recommend a stepwise therapeutic approach that combines patient education with specific allergen avoidance, symptomatic pharmacotherapy and allergen immunotherapy. The available treatment strategies provide suboptimal symptom relief in patients with moderate-to-severe disease who continue to experience symptoms while treated, even on multiple therapies. EXPERT OPINION New insights into current therapy have been provided with the development of new symptomatic drugs with improved pharmacokinetics and safety. However, the ultimate research goal is beyond symptomatic treatment, and is mainly directed at modifying the immune response to allergens and prevent the progression of allergic rhinitis towards asthma. In this direction, promising advances are expected in the fields of allergen immunotherapy and biological drugs, such as omalizumab. Finally, significant research efforts are also focused on the growing number of new specific molecular targets involved in the Th2 pathway inflammation of allergic diseases.

Abstract
UNLABELLED Sublingual immunotherapy (SLIT) for Japanese cedar pollinosis is effective, however, caution must be exercised against allergen-specific adverse events (AEs) during SLIT. PURPOSE The purpose of this study was to clarify the AEs of SLIT in a large cohort of patients with Japanese cedar pollinosis. METHODS We conducted a detailed survey, by both questionnaires and direct interviews, of 207 patients receiving SLIT at our clinic. RESULTS Eighty-four of the 207 patients (40.5%) developed AEs, with AEs involving the oral cavity and throat being the most common (56 patients; 27.1%). Sixteen patients (7.9%) had local mucosal swelling, but the swelling resolved in all the cases. Other allergen-induced symptoms such as nasal symptoms (29 events, 14.0%), eye symptoms (14 events, 6.8%) and ear symptoms (20 events, 9.7%) were also recognized. All the AEs were minor, and discontinuation of SLIT was not necessitated in any of the patients because of AEs. There were 52 AEs (25.0%) in the up-dose phase and 61 AEs (29.3%) in the maintenance phase. However, only 4 of the 161 patients (2.5%) developed AEs during the pollen season. Most AEs developing during the maintenance phase occurred in the first few weeks. In 60% of the cases, the AEs disappeared within 2 weeks, and in 6.0% (5 events), they persisted for longer than 2 months. There were no age-or sex-related differences in the prevalence of cedar pollen-specific IgE, or in the adherence to the treatment. CONCLUSION AEs in SLIT were shown in many patients, however, the severity of AEs was mild and no events interfered SLIT.

Abstract
Sublingual immunotherapy (SLIT) is a safe and effective treatment for allergic rhinitis (AR) and allergic rhinoconjunctivitis (ARC). The Food and Drug Administration (FDA) in the USA has approved three SLIT tablets for the treatment of AR and ARC in relation to pollen. Specifically, Grastek® and Oralair® are two formulations approved to treat patients suffering with AR/ARC to grass pollen, and Ragwitek™ is a formulation approved to treat patients suffering with AR/ARC to ragweed pollen. Although these approvals provide support for physicians to prescribe SLIT, barriers to prescribing SLIT still remain such as FDA approval for additional formulations, a standard dose and dosing schedule, and cost/insurance coverage. In order to further support the use of SLIT, research is currently being conducted to expand the indication for SLIT to other common comorbidities to AR/ARC. For example, allergic asthma, food allergies, and atopic dermatitis are other diseases which are being explored. The future of SLIT in the USA is unknown; however, education will be necessary for both providers and patients.

Abstract
Allergen immunotherapy with whole proteins is clinically efficacious but requires a protracted treatment period because of frequent allergic adverse events. A combination of duration of treatment and adverse events leads to poor compliance. Short synthetic peptides containing the major immunodominant T cell epitopes of allergenic proteins have been shown to reduce IgE cross-linking ability, thereby leading to fewer allergic adverse events following their administration to patients with allergies. Peptide immunotherapy has been shown to result in clinically meaningful efficacy in several Phase II, randomized, double-blind, placebo-controlled clinical trials. Exactly how peptide immunotherapy achieves its efficacy remains incompletely understood, but the mechanisms are thought to include immune deviation and induction of regulatory T cells capable of suppressing allergen-specific immune responses. Limited data are available on the effects of peptide therapy on humoral immune responses. Induction of allergen-specific IgG has been observed after peptide therapy, but the levels of antibody induced were much lower than generally seen with the utilization of whole allergen approaches. Thus, the immunological mechanisms of peptide immunotherapy appear to overlap, although not completely, with those seen in whole allergen therapy. Further studies are required to fully elucidate mechanisms of action.

Abstract
The current scientific research is continuously aiming at identifying new therapeutic targets with the purpose of modifying the immune response to allergens. The evolution in immunological methods has led to the identification of immunoglobulin E (IgE) as both a diagnostic biomarker and potential therapeutic target in allergic diseases, such as allergic rhinitis. Allergen immunotherapy has been used for more than 100 years to treat allergic diseases and it is today considered the only disease-modifying treatment capable of inducing a long-lasting immunological and clinical tolerance toward the causal allergen. During the past 20 years, major advances have been made in understanding the molecular and cellular mechanisms of allergen tolerance in humans. Moreover, there has been considerable progress in allergen extract modifications and additions to standard extracts. The recognition that IgE plays a pivotal role in basic regulatory mechanisms of allergic inflammation has recently stimulated research into the therapeutic potential of directly targeting this antibody. Omalizumab, the most advanced humanized anti-IgE monoclonal antibody, is currently approved for the treatment of uncontrolled allergic asthma and chronic spontaneous urticaria. Interesting results also arise from studies in which omalizumab was administered in patients with allergic rhinitis. The aim of this review is to provide an update on current findings on immunological and clinical effects of allergen immunotherapy and anti-IgE therapy, which have been shown to have synergistic modes of action for the treatment of allergic rhinitis.

Abstract
Background Allergy immunotherapy is an effective treatment for patients with allergic rhinitis whose symptoms are unresolved with pharmacotherapy. Allergy immunotherapy for grass pollen-induced allergic rhinitis is available in three modalities: subcutaneous immunotherapy and sublingual immunotherapy as a tablet or drop. This study aimed to understand trends in allergy immunotherapy prescribing and practice patterns for grass allergies in adult and paediatric patients in Germany. Methods A retrospective cohort study was conducted using IMS Disease Analyzer in Germany. Patients with an allergy immunotherapy prescription for grass pollen (Anatomical Therapeutic Chemical [ATC] classification code V01AA02) from September 2005 to December 2012 were included in the study. General Practitioners (GPs), dermatologists, Ear, Nose and Throat (ENT)-specialists, paediatricians and pneumologists were included as the allergy immunotherapy prescribing physicians in the study. Descriptive analyses were conducted on patient characteristics at index and prescribing physician specialty; a test for trend was conducted for timing of initiation of first allergy immunotherapy prescription in each annual prescribing season. Results Eighteen thousand eight hundred fifty eligible patients were identified during the study period. The majority of patients received subcutaneous immunotherapy; however, the proportion of patients receiving sublingual immunotherapy tablets increased from 8 % in 2006/2007 to 29 % in 2011/2012 (p < 0.001). Initiation of subcutaneous immunotherapy and Oralair® generally peaked during each prescribing year in two seasons (September-October and January) while GRAZAX® prescriptions peaked in autumn (September-October). ENT-specialists and dermatologists were the largest allergy immunotherapy prescribers in adults, while paediatricians and ENT-specialists were the largest prescribers of allergy immunotherapy in paediatric patients. Conclusions Subcutaneous immunotherapy remained the dominant allergy immunotherapy modality for grass pollen-induced allergic rhinitis in Germany for adult and paediatric patients; however, there was a marked increase in proportion of patients receiving sublingual immunotherapy tablets from 2006/2007 to 2011/2012, after their introduction to the market in 2006. ENT-specialists, dermatologists and paediatricians were responsible for the majority of prescribing. The predominance of particular modalities within certain physician specialties likely reflects different treatment goals or needs.

Abstract
Allergic diseases are prevalent worldwide. Allergen immunotherapy (AIT) is a current treatment for allergy, leading to modification of the natural course of disease. Mechanisms of efficacy include Treg through release of IL-10 and TGF-β and specific IgG4 blocking antibodies. Subcutaneous and sublingual routes are popular, but uptake is limited by inconvenience and safety concerns. Inclusion criteria limit application to a small proportion of allergic patients. New forms of immunotherapy are being investigated for more efficacious, convenient and safer options with promising advances in recent years. The rationale of reducing vaccine allergenicity to increase safety while improving immunogenicity led to investigation of T-cell epitope-based peptides and recombinant allergen derivatives. Additionally, different routes of administration and adjuvants and adjunct therapies are being explored. This review discusses the current status of AIT and recent advances to improve clinical efficacy, safety and long-term immune tolerance.

Abstract
A 35-year-old woman has a history of nasal congestion on most days of the year, dating back to her late teens. She has chronic nasal drainage, which is clear and thick. Her congestion is worst in the late summer and early fall and again in the early spring; at these times, she also has sneezing, nasal itching, and cough. Five years ago, she had an episode of shortness of breath with wheezing on a day when her nasal symptoms were severe, but this episode resolved spontaneously and has not recurred. Her eyes do not bother her. Over-the-counter oral antihistamines help her symptoms a little, as do nasal decongestants, which she uses occasionally. Her 6-year-old son has similar symptoms. How should this case be managed?

Birch pollen immunotherapy in mice: inhibition of Th2 inflammation is not sufficient to decrease airway hyper-reactivity. Int Arch Allergy Immunol 2014; 165:128-39.

Abstract
BACKGROUND Suppression of Th2 cytokine production by allergen-specific Th2 cells is considered to be critical for the suppression of allergic symptoms by subcutaneous immunotherapy. The aim of this study was to develop a mouse model for birch pollen (BP) immunotherapy to elucidate the underlying mechanisms that contribute to the improvement of clinical symptoms. METHODS Mice with BP-induced allergic airway inflammation received weekly subcutaneous immunotherapy (SCIT) injections with BP extract (BPE) adsorbed to alum. The effect of an increasing dose of BPE adsorbed to a fixed concentration of alum on the suppression of airway inflammation and airway hyper-responsiveness (AHR) was determined. After 2, 4, 6 or 8 immunotherapy injections, the mice were rechallenged with the same allergen and all hallmarks of allergic asthma were evaluated. RESULTS Suppression of the immunological parameters by immunotherapy was dependent on the BPE dose. Two injections were sufficient to suppress IL-4, IL-5, IL-13, IL-10 and IFN-γ production, eosinophil recruitment and peribronchial inflammatory infiltrates. BP-specific immunoglobulins were upregulated, but this was not sufficient to reduce AHR. Eight injections were needed to suppress AHR. The gradual reduction in AHR was inversely associated with the increase of BP IgG2a. CONCLUSIONS BP SCIT induces an early suppression of Th2-mediated eosinophilic airway inflammation, but AHR is only effectively reduced after continued SCIT conceivably by allowing IgG2a antibody titres to build up.
