Abstract
Allergen immunotherapy (AIT) is an etiological treatment strategy that involves administering escalating doses of clinically relevant allergens to desensitize the immune system. It has shown encouraging results in reducing allergy symptoms and enhancing patients' quality of life. In this review, we offer a thorough overview of AIT in China, examining its efficacy, safety, current practices, and prospects. We further underscore the progress made in AIT research and clinical applications, as well as the distinct challenges and opportunities that China faces in this area.

Abstract
Allergen immunotherapy (AIT) is a causative treatment for various allergic diseases such as allergic rhinitis, allergic asthma, and bee venom allergy that induces tolerance to offending allergens. The need for uniform practice guidelines in AIT is continuously growing because of the increasing discovery of potential candidates for AIT and evolving interest in new therapeutic approaches. This guideline is an updated version of the Korean Academy of Asthma Allergy and Clinical Immunology recommendations for AIT published in 2010. This updated guideline proposes an expert opinion by allergy, pediatrics, and otorhinolaryngology specialists with an extensive literature review. The guideline deals with basic knowledge and methodological aspects of AIT, including mechanisms, clinical efficacy, patient selection, allergens extract selection, schedule and doses, management of adverse reactions, efficacy measurements, and special consideration in pediatrics. The guidelines for sublingual immunotherapy will be covered in detail in a separate article.

Chinese Guideline on Allergen Immunotherapy for Allergic Rhinitis: The 2022 Update. ALLERGY, ASTHMA & IMMUNOLOGY RESEARCH 2022; 14:604-652. [PMID: 36426395 PMCID: PMC9709690 DOI: 10.4168/aair.2022.14.6.604] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 10/23/2022] [Accepted: 11/06/2022] [Indexed: 09/16/2023]
Abstract
In the last few decades, there has been a progressive increase in the prevalence of allergic rhinitis (AR) in China, where it now affects approximately 250 million people. AR prevention and treatment include allergen avoidance, pharmacotherapy, allergen immunotherapy (AIT), and patient education, among which AIT is the only curative intervention. AIT targets the disease etiology and may potentially modify the immune system as well as induce allergen-specific immune tolerance in patients with AR. In 2017, a team of experts from the Chinese Society of Allergy (CSA) and the Chinese Allergic Rhinitis Collaborative Research Group (C2AR2G) produced the first English version of Chinese AIT guidelines for AR. Since then, there has been considerable progress in basic research of and clinical practice for AIT, especially regarding the role of follicular regulatory T (TFR) cells in the pathogenesis of AR and the use of allergen-specific immunoglobulin E (sIgE) in nasal secretions for the diagnosis of AR. Additionally, potential biomarkers, including TFR cells, sIgG4, and sIgE, have been used to monitor the incidence and progression of AR. Moreover, there has been a novel understanding of AIT during the coronavirus disease 2019 pandemic. Hence, there was an urgent need to update the AIT guideline for AR by a team of experts from CSA and C2AR2G. This document aims to serve as professional reference material on AIT for AR treatment in China, thus improving the development of AIT across the world.

A real-world retrospective study of safety, efficacy, compliance and cost of combination treatment with rush immunotherapy plus one dose of pretreatment anti-IgE in Chinese children with respiratory allergies. Front Immunol 2022; 13:1024319. [PMID: 36268011 PMCID: PMC9577550 DOI: 10.3389/fimmu.2022.1024319] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Accepted: 09/20/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundThe efficacy of allergen immunotherapy (AIT) in treating pediatric allergy has been clearly demonstrated, however, many patients hesitate to initiate AIT due to weekly hospital visits during the 3-4 months up-dosing phase. Meanwhile, rush immunotherapy (RIT) shortens the duration of the up-dosing phase to 7 days. However, considering that patients receiving RIT are exposed to the allergens during a much shorter period of time and thus may be at a greater risk of systemic reactions, RIT is currently underused, especially in children. This study investigated the utility of combination treatment with RIT plus 1 dose of pretreatment anti-IgE in children with respiratory allergies.MethodsIn this retrospective study, we reviewed records of children with allergic rhinitis (AR) and/or allergic asthma (AA) sensitized to dust mite allergens receiving RIT+1 dose of pretreatment anti-IgE (the RIT group) or conventional immunotherapy (the CIT group) at our hospital from January 2020 to March 2021. Data such as visual analogue scale (VAS) scores, comprehensive symptom and medication score (CSMS), allergy blood test results, adverse reactions, compliance and cost were collected and analyzed.Results40 patients in the RIT group and 81 patients in the CIT group were included in this study. Both treatments were well tolerated and patients in the 2 treatment groups had comparable local and systemic reactions. Compared to CIT, RIT + anti-IgE combination led to significantly faster symptomatic improvement as demonstrated by significantly decreased VAS and CSMS starting as early as 1 month after AIT initiation (P<0.05). Nobody dropped out in the RIT group during the 1 year follow-up, while 11 out of 81 patients in the CIT group dropped out (loss rate 13.5%). Thus, the RIT group had a significantly higher compliance rate than the CIT group (P<0.05). Finally, the 2 treatment regimens had comparable cost per patient per injection (P> 0.05).ConclusionsRIT + 1 dose of pretreatment anti-IgE combination has practical advantages over CIT, including comparable safety, better compliance, and probably a faster onset of clinical efficacy at no additional cost, so it can be an useful regimen for the treatment of Chinese children with respiratory allergies.

Abstract
The pathogenesis of ulcerative colitis (UC) is unclear. House dust mite (HDM) is associated with immune inflammation in the body. This study is designed to identify the association between HDM and UC clinical symptoms. UC patients (n = 86) and non-UC control (NC) subjects (n = 64) were recruited. Colon lavage fluids (CLF) were collected from HDM skin prick test positive patients during colonoscopy, and analyzed by immunological approaches. HDM was detected in fecal samples, which was positively correlated with UC clinical symptoms. HDM-specific eosinophils and Th2 cells were detected in CLF, which could be specifically activated by exposing to HDM in the culture. Direct exposure to HDM induced eosinophil activation in the colon of UC patients. UC patients displayed elevated levels of Th2 cytokines in the serum. UC clinical symptom scores were positively correlated with serum levels of Th2 cytokines. HDM was detected in UC patients' stools, which was positively correlated with UC clinical symptoms. Direct exposure to HDM could trigger eosinophilic activation of the colon.

Abstract
Seit dem ersten Bericht über die Allergenimmuntherapie (AIT) durch Noon et al. vor 110 Jahren wurden zahlreiche klinische und grundlagenwissenschaftliche Studien durchgeführt, um die Effekte der einzigen kurativen Behandlung von Allergien zu untersuchen. Bei der atopischen Dermatitis (AD) findet sie jedoch nur selten Anwendung, obwohl es Evidenz dafür gibt, dass Aeroallergene zu Exazerbationen der Erkrankung beitragen können. Dieser Übersichtsbeitrag umfasst die aktuelle Studienlage, Metaanalysen und Leitlinienempfehlungen zur AIT bei AD-Patienten. Es zeigt sich eine große Heterogenität hinsichtlich Studiendesigns, Patientenkohorten, Allergenen, Applikationsformen und Endpunkten, wodurch die Vergleichbarkeit der Studien erschwert wird. Mehrere Untersuchungen zeigen eine positive Wirkung der AIT auf den Schweregrad der AD, was darauf hindeutet, dass zumindest eine Untergruppe von Patienten von der Behandlung profitieren kann. Weitere Entwicklungen auf dem Gebiet der AIT könnten dazu beitragen, dass die Therapie einen breiteren Einsatz bei AD-Patienten findet.

Abstract
Purpose Dupilumab is recommended to be administered biweekly to treat adult patients with moderate-to-severe atopic dermatitis (AD). Real clinical practice data on the clinical efficacy of monthly dupilumab therapy are limited. We analyzed real clinical practice data on the clinical efficacy of monthly dupilumab therapy and predictive markers for favorable clinical responses to the therapy. Methods Medical records of 57 adult patients with moderate-to-severe AD who received dupilumab therapy every 4 weeks for 16 weeks were analyzed retrospectively. Eczema Area and Severity Index (EASI) were recorded at baseline and week 16. Clinical responses to monthly dupilumab therapy were defined as the proportion of patients with decreased EASI scores of at least 50% or 75% from baseline at week 16 (EASI-50 or EASI-75). Blood eosinophil counts and serum lactate dehydrogenase (LDH) levels were measured at baseline and week 16. Results Monthly dupilumab therapy showed EASI-50 and EASI-75 clinical responses in 48 (84.2%) and 27 (47.4%) of 57 patients at week 16, respectively. The percentage decrease in EASI scores from baseline at week 16 was significantly inversely correlated with baseline blood eosinophil count (correlation coefficient [r] = −0.405, P = 0.002) and baseline serum LDH level (r = −0.466, P < 0.001). The EASI-75 response rate was higher in patients with low (< 500/µL, 73.3%) than in those with high (≥ 500/µL, 37.5%) baseline blood eosinophil counts (P = 0.032), and was higher in patients with low (< 400 U/L, 55.6%) than those with high (≥ 400 U/L, 10.0%) baseline serum LDH levels (P = 0.013). Conclusions Monthly dupilumab therapy was clinically effective in adult patients with moderate-to-severe AD in real clinical practice. Baseline blood eosinophil count and serum LDH level could be predictive markers for clinical response to dupilumab therapy.

Abstract
Background Most previous studies used aluminum hydroxide-absorbed allergen extracts in evaluating the potential therapeutic roles of intralymphatic allergen-specific immunotherapy (ILAIT). In this study, we evaluated the therapeutic efficacy and safety of ILAIT with L-tyrosine-adsorbed allergen extracts of Dermatophagoides farinae, D. pteronyssinus, cat, dog, or mixtures thereof, in patients with allergic rhinitis induced by these allergens. Methods In this randomized, double-blind, placebo-controlled trial, study subjects received three intralymphatic injections of L-tyrosine-adsorbed allergen extracts (active group) or saline (placebo group) at 4-week intervals. Results Although ILAIT reduced daily medication use and skin reactivity to HDM and cat allergens at 4 months after treatment, overall symptom score on a visual analog scale (VAS), sinonasal outcome test-20 (SNOT-20), rhinoconjunctivitis quality of life questionnaire (RQLQ), daily symptom score (dSS), daily medication score (dMS), daily symptom medication score (dSMS), nasal reactivity to HDM allergen, and basophil activity to HDM, cat, and dog allergens at 4 months and 1 year after treatment were similar between the treatment and control groups. Intralymphatic injection was more painful than a venous puncture, and pain at the injection site was the most frequent local adverse event (12.8%); dyspnea and wheezing were the most common systemic adverse events (5.3%). Conclusions ILAIT with L-tyrosine-adsorbed allergen extracts does not exhibit profound therapeutic efficacy in allergic rhinitis and can provoke moderate-to-severe systemic reactions and cause pain at the injection site.
