TL;DR: In this article, the authors conducted a web-based retrospective survey (SurveyMonkey®) including 27 standardized questions on practical and safety aspects on AIT in worldwide clinical routine.
Abstract: Background As in many fields of medical care, the coronavirus disease 2019 (COVID-19) resulted in an increased uncertainty regarding the safety of allergen immunotherapy (AIT). Therefore, the European Academy of Allergy and Clinical Immunology (EAACI) aimed to analyze the situation in different countries and systematically collect all information available regarding tolerability and possible amendments in daily practice of sublingual AIT (SLIT), subcutaneous AIT (SCIT) for inhalant allergies and venom AIT. Method Under the framework of the EAACI, a panel of experts in the field of AIT coordinated by the Immunotherapy Interest Group (IT IG) set-up a web-based retrospective survey (SurveyMonkey®) including 27 standardized questions on practical and safety aspects on AIT in worldwide clinical routine. Results 417 respondents providing AIT to their patients in daily routine answered the survey. For patients (without any current symptoms to suspect COVID-19), 60% of the respondents informed of not having initiated SCIT (40% venom AIT, 35% SLIT) whereas for the maintenance phase of AIT, SCIT was performed by 75% of the respondents (74% venom AIT, 89% SLIT). No tolerability concern arises from this preliminary analysis. 16 physicians reported having performed AIT despite (early) symptoms of COVID-19 and/or a positive test result for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Conclusions This first international retrospective survey in atopic diseases investigated practical aspects and tolerability of AIT during the COVID-19 pandemic and gave no concerns regarding reduced tolerability under real-life circumstances. However, the data indicate an undertreatment of AIT, which may be temporary, but could have a long-lasting negative impact on the clinical care of allergic patients.

TL;DR: The evidence for its clinical efficacy and safety is broad and undisputed, and more insights into the underlying mechanisms, in particular the modulation of innate and adaptive immune responses, have been described as discussed by the authors.
Abstract: One hundred and ten years after Noon's first clinical report of the subcutaneous application of allergen extracts, allergen immunotherapy (AIT) has evolved as the most important pillar of the treatment of allergic patients. It is the only disease-modifying treatment option available and the evidence for its clinical efficacy and safety is broad and undisputed. Throughout recent decades, more insights into the underlying mechanisms, in particular the modulation of innate and adaptive immune responses, have been described. AIT is acknowledged by worldwide regulatory authorities, and following the regulatory guidelines for product development, AIT products are subject to a rigorous evaluation before obtaining market authorization. Knowledge and practice are anchored in international guidelines, such as the recently published series of the European Academy of Allergy and Clinical Immunology (EAACI). Innovative approaches continue to be further developed with the focus on clinical improvement by, for example, the usage of adjuvants, peptides, recombinants, modification of allergens, new routes of administration, and the concomitant use of biologicals. In addition, real-life data provide complementary and valuable information on the effectiveness and tolerability of this treatment option in the clinical routine. New mobile health technologies and big-data approaches will improve daily treatment convenience, adherence, and efficacy of AIT. However, the current coronavirus disease 2019 (COVID-19) pandemic has also had some implications for the feasibility and practicability of AIT. Taken together, AIT as the only disease-modifying therapy in allergic diseases has been broadly investigated over the past 110 years laying the path for innovations and further improvement.

TL;DR: In this paper, a survey was conducted by the European Academy of Allergy and Clinical Immunology (EAACI) via e-mail, website, and social media to EAACI members and members of peer societies.
Abstract: BACKGROUND: The restrictions imposed by the COVID-19 pandemic impact heavily the management of chronic diseases like asthma. This study aimed to evaluate the management of adults and children with asthma during COVID-19-related lockdown. METHODS: A survey was launched by the European Academy of Allergy and Clinical Immunology (EAACI) via e-mail, website, and social media to EAACI members and members of peer societies. RESULTS: The survey was completed by 339 healthcare professionals from 52 countries. 79% of follow-up consultations were replaced by phone calls, whereas 49% of newly referred patients attended the clinic. 62%, 76%, 66%, 76%, and 87% of responders did not conduct spirometry, impulse oscillometry, bronchodilator test, FeNO, or methacholine provocation, respectively, for asthma diagnosis in adults. The numbers were similar for children. 73% of responders based the initial asthma diagnosis and the prescription of inhaled therapy on clinical parameters only. Lung function tests were used in 29% of cases to monitor asthma worsening, and only 56% of participants were recommended to their patients ambulatory peak expiratory flow (PEF) measurements. Using a 1 (not at all) to 5 (very much) scale, the responders considered that the quality of healthcare provided and the patients' asthma status had deteriorated during the lockdown with 3.2 points and 2.8 points, respectively. CONCLUSION: Collectively, these results suggest that all necessary resources should be allocated to ensure the performance of lung function tests for initial diagnosis, whereas digital remote monitoring should be reinforced for the follow-up of children and adults with asthma.

TL;DR: In this paper, the authors investigated adherence to SCIT with aeroallergens during the COVID-19 pandemic and demonstrate clinical consequences of treatment disruptions in real life.
Abstract: BACKGROUND: The success of subcutaneous immunotherapy (SCIT) mostly depends on regular injections. Our aim was to investigate adherence to SCIT with aeroallergens during the COVID-19 pandemic and demonstrate clinical consequences of treatment disruptions in real life. METHODS: Visual analogue scale for quality of life (VAS-QoL), VAS for symptom scores (VAS-symptom), medication scores (MSs), and total symptom scores (TSS-6) were recorded during the pandemic in 327 adult allergic rhinitis and/or asthmatic patients receiving maintenance SCIT, and these scores were compared with the pre-pandemic data. Patients were grouped according to SCIT administration intervals; no delay (Group 1), <2 months (Group 2), and ≥2-month intervals (Group 3). RESULTS: A total of 104 (31.8%) patients (Group 3) were considered as nonadherent which was mostly related to receiving SCIT with HDMs and using public transportation for reaching the hospital. Median MS, VAS-symptom, and TSS-6 scores of Group 3 patients during the pandemic were higher than the pre-pandemic scores (p = 0.005, p < 0.001, p < 0.001, respectively), whereas median VAS-QoL scores of Group 3 during the pandemic were lower than the pre-pandemic scores (p < 0.001). Median TSS-6 and VAS-symptom scores were the highest in Group 3 compared with other groups (p < 0.001 for each comparison). Median VAS-QoL scores were the lowest in Group 3 compared with Group 1 and Group 2 (p < 0.001, p = 0.043, respectively). CONCLUSION: When precautions in allergy clinics are carefully applied, adherence to SCIT can be high during a pandemic. Patients must be encouraged to regularly adhere to SCIT injections since delays in SCIT administration can deteriorate clinical symptoms.

TL;DR: HCPs providing care to allergic patients were affected during the COVID‐19 pandemic in diagnostic, management, and therapeutic approaches, including AIT for respiratory, insect‐venom, and food allergies.
Abstract: Abstract Background The COVID‐19 pandemic has affected health care systems unexpectedly. However, data focusing on practical considerations experienced by health care professionals (HCPs) providing care to allergic patients is scarce. Methods Under the framework of the European Academy of Allergy and Clinical Immunology (EAACI), a panel of experts in the field of immunotherapy developed a 42‐question online survey, to evaluate real‐life consequences of the COVID‐19 pandemic in allergy practice. Results The respondents in the survey were 618. About 80% of HCPs indicated being significantly affected in their allergy practice. A face‐to‐face visit reduction was reported by 93% of HCPs and about a quarter completely interrupted diagnostic challenges. Patients with severe uncontrolled asthma (59%) and anaphylaxis (47%) were prioritized for in‐person care. About 81% maintained an unaltered prescription of inhaled corticosteroids (ICS) in asthmatics. About 90% did not modify intranasal corticosteroids (INCS) in patients with allergic rhinitis. Nearly half of respondents kept biological prescriptions unmodified for asthma. About 50% of respondents kept their allergen immunotherapy (AIT) prescription patterns unchanged for respiratory allergies; 60% for insect venom allergies. Oral immunotherapy (OIT) for food allergies was initiated by 27%. About 20% kept carrying out up‐dosing without modifications and 14% changed to more prolonged intervals. Telemedicine practice was increased. Conclusions HCPs providing care to allergic patients were affected during the pandemic in diagnostic, management, and therapeutic approaches, including AIT for respiratory, insect‐venom, and food allergies. Most HCPs maintained controller treatments for both asthma, and allergic rhinitis consistent with international recommendations, as well as biological agents in asthma. Remote tools are valuable in delivering allergy care.

TL;DR: In this paper, the authors provide specific recommendations for the use of AIT in temporal relation to a SARS-CoV-2 vaccination, in which they recommend an interval of 1 week before and after vaccination for subcutaneous immunotherapy (SCIT).
Abstract: Background Vaccinations against severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) are intended to induce an immune response to protect against infection/disease. Allergen immunotherapy (AIT) is thought to induce a (different) immune response, e.g., to induce tolerance to allergens. In this position paper we clarify how to use AIT in temporal relation to COVID-19 vaccination. Four SARS-CoV-2 vaccines are currently approved in the EU, and their possible immunological interactions with AIT are described together with practical recommendations for use. Materials and methods Based on the internationally published literature, this position paper provides specific recommendations for the use of AIT in temporal relation to a SARS-CoV-2 vaccination. Results AIT is used in 1) allergic rhinitis, 2) allergic bronchial asthma, 3) insect venom allergy, 4) food allergy (peanut). Conclusion For the continuation of an ongoing AIT, we recommend an interval of 1 week before and after vaccination for subcutaneous immunotherapy (SCIT). For sublingual immunotherapy (SLIT) and oral immunotherapy (OIT), we recommend taking them up to the day before vaccination and a break of 2 - 7 days after vaccination. Initiation of a new SCIT, SLIT, or OIT should be delayed until 1 week after the day of the second vaccination. For SCIT, we generally recommend an interval of ~ 1 week to COVID-19 vaccination.
