J Clin Med 2024; 13:4222. [PMID: 39064262 PMCID: PMC11278189 DOI: 10.3390/jcm13144222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2024] [Revised: 07/14/2024] [Accepted: 07/17/2024] [Indexed: 07/28/2024] Open
Abstract
Thirty years have passed since the concept of latex-fruit syndrome (LFS) was first introduced. Since then, this phenomenon, characterized by cross-reactivity between natural latex rubber allergens and certain fruit allergens, has been extensively studied. This literature review sought to determine the prevalence of LFS in latex-allergic patients, identify the most common cross-reactions with fruit allergens in individuals with LFS, and understand the clinical manifestations of this syndrome. An extensive literature search was carried out using PubMed and Scopus databases, while applying the Preferred Reporting Items for Systematic Reviews and Meta-Analysis methodology. The analysis of original studies revealed a wide variation in LFS prevalence (4-88%) influenced by diverse diagnostic tools, different geographical regions, and the size of study populations. Our findings indicate that the most prevalent allergenic fruits in patients with LFS are banana, avocado, kiwifruit, and papaya. After evaluating the symptoms of the fruit hypersensitivity of patients with LFS, the clinical manifestation of hypersensitivity constituted 73% of systemic allergy symptoms and only 27% of reported symptoms described the localized allergy. Furthermore, the clinical picture of latex-fruit syndrome is illustrated through two cases, one typical and one with an unusual presentation. Their clinical features were assessed and contrasted utilizing different anaphylaxis severity grading criteria. To properly manage LFS, it is essential to establish standardized diagnostic criteria and severity grading systems, as these are crucial for accurate diagnosis and effective treatment.

[PMID: 38611357 PMCID: PMC11012157 DOI: 10.3390/foods13071052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 03/21/2024] [Accepted: 03/23/2024] [Indexed: 04/14/2024] Open
Abstract
Presently, there has been an increase in the consumption of the blue-green microalga-spirulina (Arthrospira species), which dominates 99.5% of the total world production of microalgae. Primarily sold as a dietary supplement, it is also incorporated into snacks, pasta, cookies, and bread. Owing to its nutrient abundance, spirulina has a variety of potential applications. Extensive studies have been conducted on the health benefits of spirulina, but its safety in terms of allergy has received limited attention. Therefore, to bridge this knowledge deficit, this review aimed to evaluate the allergenic and antiallergic potential of spirulina. In the PubMed and Scopus databases using words related to allergy, we attempted to detect papers on hypersensitivity to spirulina. A total of 128 records were identified, of which 49 were screened. Ultimately, in this review, we analyzed four case studies, encompassing a total of five patients with allergies to spirulina. We assessed the severity of allergic reactions following World Allergy Organization (WAO) Anaphylaxis Guidance 2020, which varied from mild (grade 2) to severe (grade 4) based on the patient's symptoms. Additionally, our findings indicate that allergy to spirulina is not commonly reported or diagnosed. However, most of the described cases (four of five) regarding allergy to spirulina according to WAO Anaphylaxis Guidance 2020 were classified as anaphylaxis. Furthermore, it is noteworthy that spirulina also possesses antiallergic properties, as evidenced by research studies. Our article delves into both the allergic and antiallergic potential of spirulina.

Kačar M, Košnik M. Evaluating Hymenoptera Venom Allergy Severity: A Data-Centric Comparison of Grading Instruments. Int Arch Allergy Immunol 2024; 185:694-703.

Abstract
INTRODUCTION While a consensus seems to have been reached with regard to the definition of anaphylaxis, there is no universal instrument for scoring allergic reaction severity despite more than 30 having been proposed by the time of writing. This severely hampers comparison of data between studies. While scales have been compared with regard to their utility in grading food-related reactions, no such comparisons have been made for Hymenoptera venom-associated reactions. METHODS The study conducted a retrospective analysis to compare the severity of Hymenoptera venom allergy reactions in 104 participants with suspected Hymenoptera venom allergy. The study applied six grading instruments to each reaction, also evaluating them against the NIAID/FAAN anaphylaxis criteria. Sensitivity, specificity, and receiver operating characteristic area under the curve (AUC) for identifying anaphylaxis were calculated. Severity scales were simplified into "mild," "moderate," and "severe" categories. The most common severity grade across the five scales was determined using a custom function to establish a consensus severity grade. RESULTS The most common culprit insects were honeybees (49.0%). Among the 88 participants with generalized reactions, the highest proportion had involvement of four organ systems. The scales showed high specificity for detecting anaphylaxis, especially when using higher grades of the Mueller, WAO, and Dribin scales. The diagnostic yields (AUC) varied, with the WAO scale having the highest AUC (0.94) for grades 3, 4, and 5. Spearman correlation analysis showed the strongest correlations seen between the Brown and Dribin, Ring and Messmer and Dribin, and Ring and Messmer and Reisman scales. The lowest correlations were observed with the Mueller scale when paired with the WAO, Reisman, and Dribin scales. An inter-rater reliability analysis showed substantial agreement between scales with the same number of grading levels. The agreement was highest for the Brown and Dribin scales, indicating a strong consistency in reaction severity classification across different instruments. CONCLUSION While all instruments were effective in stratifying reactions, they showed limitations in differentiating milder phenotypes. The Brown and Dribin scales stood out for their high agreement with the consensus score and sensitivity in identifying anaphylaxis. Our findings suggest that adopting either of these scales could significantly unify the reporting of allergic reactions. We believe the format of an instrument should be tailored to its intended purpose, with clinical decision aids being simpler and research tools being more detailed.

Abstract
There is a lack of consensus over the description and severity assignment of allergic adverse reactions to immunotherapy, although there seems to be a consensus at least in terms of using the World Allergy Organization (WAO) grading systems to describe local adverse events for Sublingual Immunotherapy (SLIT) and Systemic Allergic Reactions (SARs) to Subcutaneous Immunotherapy (SCIT) amongst the major national/regional allergy societies. In this manuscript, we propose a modification of the previous WAO Grading system for SARs, which aligns with the newly-proposed Consortium for Food Allergy Research (CoFAR) Grading Scale for Systemic Allergic Reactions in Food Allergy (version 3.0). We hope this can facilitate a unified grading system appropriate to SARs due to allergen immunotherapy, independent of allergen and route of administration, and across clinical and research practice.

Clinical Practice Guideline: Immunotherapy for Inhalant Allergy. Otolaryngol Head Neck Surg 2024; 170 Suppl 1:S1-S42. [PMID: 38408152 DOI: 10.1002/ohn.648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Accepted: 01/02/2024] [Indexed: 02/28/2024]
Abstract
OBJECTIVE Allergen immunotherapy (AIT) is the therapeutic exposure to an allergen or allergens selected by clinical assessment and allergy testing to decrease allergic symptoms and induce immunologic tolerance. Inhalant AIT is administered to millions of patients for allergic rhinitis (AR) and allergic asthma (AA) and is most commonly delivered as subcutaneous immunotherapy (SCIT) or sublingual immunotherapy (SLIT). Despite its widespread use, there is variability in the initiation and delivery of safe and effective immunotherapy, and there are opportunities for evidence-based recommendations for improved patient care. PURPOSE The purpose of this clinical practice guideline (CPG) is to identify quality improvement opportunities and provide clinicians trustworthy, evidence-based recommendations regarding the management of inhaled allergies with immunotherapy. Specific goals of the guideline are to optimize patient care, promote safe and effective therapy, reduce unjustified variations in care, and reduce the risk of harm. The target patients for the guideline are any individuals aged 5 years and older with AR, with or without AA, who are either candidates for immunotherapy or treated with immunotherapy for their inhalant allergies. The target audience is all clinicians involved in the administration of immunotherapy. This guideline is intended to focus on evidence-based quality improvement opportunities judged most important by the guideline development group (GDG). It is not intended to be a comprehensive, general guide regarding the management of inhaled allergies with immunotherapy. The statements in this guideline are not intended to limit or restrict care provided by clinicians based on their experience and assessment of individual patients. ACTION STATEMENTS The GDG made a strong recommendation that (Key Action Statement [KAS] 10) the clinician performing allergy skin testing or administering AIT must be able to diagnose and manage anaphylaxis. The GDG made recommendations for the following KASs: (KAS 1) Clinicians should offer or refer to a clinician who can offer immunotherapy for patients with AR with or without AA if their patients' symptoms are inadequately controlled with medical therapy, allergen avoidance, or both, or have a preference for immunomodulation. (KAS 2A) Clinicians should not initiate AIT for patients who are pregnant, have uncontrolled asthma, or are unable to tolerate injectable epinephrine. (KAS 3) Clinicians should evaluate the patient or refer the patient to a clinician who can evaluate for signs and symptoms of asthma before initiating AIT and for signs and symptoms of uncontrolled asthma before administering subsequent AIT. (KAS 4) Clinicians should educate patients who are immunotherapy candidates regarding the differences between SCIT and SLIT (aqueous and tablet) including risks, benefits, convenience, and costs. (KAS 5) Clinicians should educate patients about the potential benefits of AIT in (1) preventing new allergen sensitizations, (2) reducing the risk of developing AA, and (3) altering the natural history of the disease with continued benefit after discontinuation of therapy. (KAS 6) Clinicians who administer SLIT to patients with seasonal AR should offer pre- and co-seasonal immunotherapy. (KAS 7) Clinicians prescribing AIT should limit treatment to only those clinically relevant allergens that correlate with the patient's history and are confirmed by testing. (KAS 9) Clinicians administering AIT should continue escalation or maintenance dosing when patients have local reactions (LRs) to AIT. (KAS 11) Clinicians should avoid repeat allergy testing as an assessment of the efficacy of ongoing AIT unless there is a change in environmental exposures or a loss of control of symptoms. (KAS 12) For patients who are experiencing symptomatic control from AIT, clinicians should treat for a minimum duration of 3 years, with ongoing treatment duration based on patient response to treatment. The GDG offered the following KASs as options: (KAS 2B) Clinicians may choose not to initiate AIT for patients who use concomitant beta-blockers, have a history of anaphylaxis, have systemic immunosuppression, or have eosinophilic esophagitis (SLIT only). (KAS 8) Clinicians may treat polysensitized patients with a limited number of allergens.

Anaphylaxis: A 2023 practice parameter update. Ann Allergy Asthma Immunol 2024; 132:124-176. [PMID: 38108678 DOI: 10.1016/j.anai.2023.09.015] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 09/29/2023] [Accepted: 09/29/2023] [Indexed: 12/19/2023]
Abstract
This practice parameter update focuses on 7 areas in which there are new evidence and new recommendations. Diagnostic criteria for anaphylaxis have been revised, and patterns of anaphylaxis are defined. Measurement of serum tryptase is important for diagnosis of anaphylaxis and to identify underlying mast cell disorders. In infants and toddlers, age-specific symptoms may differ from older children and adults, patient age is not correlated with reaction severity, and anaphylaxis is unlikely to be the initial reaction to an allergen on first exposure. Different community settings for anaphylaxis require specific measures for prevention and treatment of anaphylaxis. Optimal prescribing and use of epinephrine autoinjector devices require specific counseling and training of patients and caregivers, including when and how to administer the epinephrine autoinjector and whether and when to call 911. If epinephrine is used promptly, immediate activation of emergency medical services may not be required if the patient experiences a prompt, complete, and durable response. For most medical indications, the risk of stopping or changing beta-blocker or angiotensin-converting enzyme inhibitor medication may exceed the risk of more severe anaphylaxis if the medication is continued, especially in patients with insect sting anaphylaxis. Evaluation for mastocytosis, including a bone marrow biopsy, should be considered for adult patients with severe insect sting anaphylaxis or recurrent idiopathic anaphylaxis. After perioperative anaphylaxis, repeat anesthesia may proceed in the context of shared decision-making and based on the history and results of diagnostic evaluation with skin tests or in vitro tests when available, and supervised challenge when necessary.

[PMID: 37972922 DOI: 10.1016/j.jaip.2023.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 11/03/2023] [Accepted: 11/07/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND There is no consensus method to identify anaphylaxis in sublingual immunotherapy (SLIT) trials. Standardized Medical Dictionary for Regulatory Activities (MedDRA) queries (SMQs) are standardized groupings of MedDRA terms used in drug safety monitoring. OBJECTIVE To develop a method to identify potential anaphylaxis in SLIT-tablet trials using SMQ searches and case definitions of anaphylaxis adopted from the National Institute of Allergy and Infectious Disease. METHODS The SMQ search tool contained 2 criteria including treatment-emergent adverse events (AEs): (1) narrow MedDRA terms related to anaphylaxis and (2) all AEs with broad MedDRA terms from at least 2 of 3 categories (respiratory/skin/cardiovascular) occurring on the same day. Criteria were applied to a pooled data set of all subjects from 48 timothy grass, ragweed, house dust mite, and tree SLIT-tablet trials (SLIT-tablet, N = 8200; placebo, N = 7033). Additional search strategies were any treatment-emergent AE with MedDRA preferred term "hypersensitivity" and epinephrine administrations. Identified potential cases underwent blinded independent medical expert review. Nonanaphylaxis cases were designated local AEs or mild to moderate systemic reactions. RESULTS Using the SMQ search tool and after subsequent medical review, 8 anaphylaxis cases were identified; 3 were considered treatment-related, resulting in a proportion of anaphylaxis cases/subject of 0.02% (2 of 8200) with SLIT-tablet and 0.01% (1 of 7033) with placebo. One additional anaphylaxis case related to SLIT-tablet was identified by the preferred term "hypersensitivity." The 3 anaphylaxis cases associated with SLIT-tablet treatment were not life-threatening. The epinephrine administration rate was 17 of 8200 (0.2%) with SLIT-tablet treatment and 2 of 7033 (0.03%) with placebo. CONCLUSIONS SMQ search criteria for identifying potential anaphylaxis related to SLIT were developed. Anaphylaxis was rare for SLIT-tablets.

Patient Adherence to Written Instructions following Complete Allergological Evaluation for Suspected Beta-Lactam Allergy: A Tertiary Hospital Study in Greece. J Pers Med 2023; 13:1719. [PMID: 38138946 PMCID: PMC10745116 DOI: 10.3390/jpm13121719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 12/05/2023] [Accepted: 12/15/2023] [Indexed: 12/24/2023] Open
Abstract
BACKGROUND Beta-lactam (BL) antibiotics are among the most prescribed groups of drugs worldwide and have been implicated in a variety of allergic reactions. There is a paucity of literature regarding patient adherence to prescribed instructions following comprehensive allergy assessments. OBJECTIVE The objective was to follow up the clinical course of BL allergy in patients who underwent thorough allergological investigation for suspected BL allergy at a tertiary hospital and ascertain patients' compliance with the provided written instructions. MATERIALS An observational study in patients referred for suspected BL allergy who underwent a comprehensive allergy workup (in vivo ± in vitro tests, DPT in culprit and/or alternative BL) and who subsequently received written instructions was conducted. Data on the nature of the reported drug hypersensitivity reaction, the culprit BL drug, the allergological workup, and the detailed instructions provided in a written drug allergy report were collected retrospectively. Patients' compliance with the instructions was recorded by a telephone survey using a pre-defined questionnaire. RESULTS Among the 212 patients meeting the inclusion criteria, 87 patients (72.4% women; mean age 50.1 years; age range 6-84 years) responded to the telephone survey and were included in this study. Surprisingly, 45 out of 87 (51.7%) patients did not adhere to the written instructions. The primary factor contributing to non-compliance was the fear of re-occurrence of a drug-induced allergic reaction (personal and/or triggered by their treating physician reluctance), accounting for 77.7% of cases. The analysis demonstrated that the initial reaction's severity and type, as well as the outcomes of skin testing, did not correlate with compliance to instructions (p > 0.05). Surprisingly enough, a drug provocation test (DPT), irrespectively of the result, emerged as a negative predictor for adherence, with only 40.6% of DPT patients complying compared to 77.8% of those who did not undergo DPT (p = 0.005; odds ratio = 0.195; 95% confidence interval: 0.058-0.655). Variables such as performing DPT with alternative or incriminated drugs or the result of the DPT (positive-negative) were not associated with patient compliance. Conversely, the type of instructions provided exhibited a noteworthy correlation with compliance. Patients who were explicitly instructed to entirely avoid all BL antibiotics demonstrated markedly higher adherence rates (83.3%) compared to those who were advised to have a partial or complete release of BLs (31.8% and 58.1%, respectively; p < 0.05). Notably, among compliant patients who received either the original culprit drug or the alternative (32 out of 87, 36.7%), no allergic reactions were reported. In contrast, among the 12 patients with written avoidance of all BLs, subsequent BL intake led to immediate reactions (Grade I and IV) in 2 patients (16.6%). CONCLUSIONS A notable disparity in patient adherence to written instructions prohibiting or releasing beta-lactams was demonstrated. Less than half of the patients ultimately complied with the provided instructions, underscoring the need for tailored patients' education and strategies to improve adherence in the management of suspected BL allergy.

United States Drug Allergy Registry (USDAR) grading scale for immediate drug reactions. J Allergy Clin Immunol 2023; 152:1581-1586.

Abstract
BACKGROUND There is no accepted grading system classifying the severity of immediate reactions to drugs. OBJECTIVE The purpose of this article is to present a proposed grading system developed through the consensus of drug allergy experts from the United States Drug Allergy Registry (USDAR) Consortium. METHODS The USDAR investigators sought to develop a consensus severity grading system for immediate drug reactions that is applicable to clinical care and research. RESULTS The USDAR grading scale scores severity levels on a scale of 0 to 4. A grade of no reaction (NR) is used for patients who undergo challenge without any symptoms or signs, and it would confirm a negative challenge result. A grade 0 reaction is indicative of primarily subjective complaints that are commonly seen with both historical drug reactions and during drug challenges, and it would suggest a low likelihood of a true drug allergic reaction. Grades 1 to 4 meet the criteria for a positive challenge result and may be considered indicative of a drug allergy. Grade 1 reactions are suggestive of a potential immediate drug reaction with mild symptoms. Grade 2 reactions are more likely to be immediate drug reactions of moderate severity. Grade 3 reactions have features suggestive of a severe allergic reaction, whereas grade 4 reactions are life-threatening reactions such as anaphylactic shock and fatal anaphylaxis. CONCLUSION This proposed grading schema for immediate drug reactions improves on prior schemata by being developed specifically for immediate drug reactions and being easy to implement in clinical and research practice.

Abstract
AIM The incidence of anaphylaxis is increasing globally in tandem with changing environmental and lifestyle factors. There is very limited data on very early childhood presentations. We aim to assess changes in rates, characteristics and management of infant anaphylaxis in a paediatric ED over a 15-year period. METHODS We conducted a retrospective study of children <2 years of age who presented with verified anaphylaxis comparing cases in years 2003-2007 with those in 2013-2017. Standardised information was collected on demographics, clinical presentation, management and triggers. RESULTS Manually confirmed anaphylaxis rates in <2 year olds increased from 3.6 to 6.2 per 104 population (OR 1.7, 95% CI: 1.3-2.7; p < 0.001) with the greatest increase in <1 year olds. Anaphylaxis severity increased between 2003-2007 and 2013-2017 (OR 2.3, 95% CI: 1.2-4.3; p = 0.018). Failure to administer adrenaline was reduced in 2013-2017 (p = 0.007). Food was the leading anaphylaxis trigger (97.85%). CONCLUSION This is the first study to suggest an increase in the incidence and severity of ED anaphylaxis presentations in children aged <2 years. Increased awareness of specific characteristics in this age group is required to facilitate timely recognition and optimal management. Further large-scale studies are warranted to understand underlying environmental drivers and find prevention strategies to reduce the burden of disease.

Abstract
OBJECTIVE To characterize anaphylactic reactions in dogs, including clinical signs, severity, treatments, prognosis, and estimated incidence. To determine whether glucocorticoids influence clinical recovery and survival. DESIGN Retrospective study between January 1, 2003 and April 28, 2014. SETTING University teaching hospital. ANIMALS Eighty-six dogs treated for a type I hypersensitivity reaction. Nineteen dogs fulfilled the criteria for anaphylaxis, and 67 dogs had mild cutaneous reactions. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The estimated incidence was 0.04% for anaphylaxis and 0.15% for mild hypersensitivity reactions. The female:male ratio (2.3:1) was significantly higher (P = 0.032) compared to our source population (ratio of 1:1.158). Vaccines were the most frequent trigger for anaphylaxis (57.9%) and mild hypersensitivity reactions (28.4%). Seventy-four (86%) dogs had cutaneous signs, and 11 (57.9%) dogs with anaphylaxis had no cutaneous signs reported. Forty-two (48.8%) dogs received both an H1 antagonist and a glucocorticoid, 34 (39.5%) dogs received an H1 antagonist only, and 6 (6.9%) dogs received a glucocorticoid only. The majority of the dogs survived, and 1 was euthanized due to complications. Clinical signs associated with nonsurvival included respiratory signs (P = 0.006), particularly respiratory distress (P < 0.00001) and cyanosis (P < 0.00001), and circulatory shock (P = 0.005). The analysis of the interaction between etiology, clinical signs, treatment, and outcome did not show any association between pairs of variables. CONCLUSIONS In the current study, anaphylaxis had a relatively good prognosis, and cutaneous signs were not always present. Based on the present data, the use of glucocorticoids to treat mild type I hypersensitivity reactions and anaphylaxis in dogs was not associated with clinical improvement or survival.

Abstract
Numerous scoring systems have been developed to improve and standardize the diagnosis and management of acute allergic reactions and anaphylaxis; however, considerable variability exists among these systems. This review article discusses existing severity scoring systems and identifies specific knowledge gaps that remain. Future research is needed to resolve the limitations of existing grading systems, including attempting to link reaction severity with treatment advice and conducting validation studies in different clinical settings, patient populations, and geographies to promote grading system application and dissemination in both clinical care and research.

Abstract
Subcutaneous immunotherapy (SCIT), commonly known as "allergy shots," aims to achieve a clinical tolerance for allergens that cause symptoms of allergic rhinoconjunctivitis, allergic asthma, or insect sting allergies. Systemic reactions to SCIT are classified in severity from one organ system (grade 1) to anaphylaxis that potentially may have a fatal outcome (grade 5). Uterine cramps fall under grade 2, and they are rarely reported during SCIT. In this study, we report four cases of uterine anaphylaxis following SCIT for environmental allergens with symptoms such as severe lower abdominal cramping resembling menstrual cramps. Patients also experienced urticaria, angioedema, diffuse erythema, and flushing. None of the patients experienced uterine bleeding. To the best of our knowledge, this is the largest case series reporting this reaction to SCIT. We accompany this finding with a review of the literature on this rare but interesting topic.

Abstract
Allergic rhinitis (AR) is an IgE-mediated inflammatory disease of the upper airway. AR affects the patients' quality of life, is a known risk factor for asthma and a socio-economic burden. Allergen-specific immunotherapy (AIT), comprising sublingual immunotherapy (SLIT) and subcutaneous immunotherapy (SCIT), involves administering increasing doses of the causative allergen to induce clinical and immunologic tolerance to the allergens. It is the only currently available treatment for AR that has been proven to induce disease-modifying effects (i.e., long-term remission of allergic symptoms or potential prevention of asthma and new sensitizations). Although AIT is conventionally recommended for patients who are non-responsive to symptom-relieving pharmacotherapy, it is presently recommended as a first-line treatment for patients with moderate to severe AR who prefer a treatment with the potential for long-term remission. In light of the relatively recent implementation of AIT in Malaysia, guidelines on its appropriate indication and application are important to attain optimal outcomes. This consensus statement was developed by an expert group formed by the Malaysian Society of Allergy and Immunology to provide evidence-based recommendations for the practice of AIT in Malaysia. Patient and product selection, choice of AIT, and strategy towards an effective treatment outcome in AIT are presented.

Abstract
Purpose of Review Allergen immunotherapy (AIT) is a novel treatment approach with disease-modifying and preventative benefits that are not shared with other strategies for treating allergic illnesses. It has been demonstrated to be safe and effective in children. This review provides the most recent information on AIT in children as well as any pertinent updates. Recent Findings Although there is not a standard way to begin AIT, there are clear indications for AIT. Each case needs to be evaluated on its own by weighing the pros and downsides. AIT has been proven to significantly improve symptoms and quality of life in children with allergic illness, reduce medication use, stop the development of new allergen sensitizations, and stop the progression of allergic rhinitis to asthma. Novel approaches are under investigation to overcome some known AIT disadvantages. Summary This review provides a thorough summary of the most recent research and updates on AIT in children.

The percentage of reported antibiotic allergies is likely to differ from the one validated after a drug provocation test (DPT) with the culprit antibiotic. This study aimed to compare the percentage of children who were thought to be allergic to a certain antibiotic with those who have a true allergy, as confirmed by DPTs. We also validated Skin Prick Tests (SPTs) and Intradermal Tests (IDTs) by assessing their sensitivity and specificity, in diagnosing antibiotic allergies using DPT as the gold standard. Furthermore, we investigated epidemiological risk factors such as personal and family history of atopic disease and eosinophilia. Methods Children with a history of possible allergic reaction to an antibiotic underwent a diagnostic procedure that included: (1) Eosinophil blood count, (2) SPTs, (3) IDTs and (4) DPTs. The parameters were compared with Pearson's Chi-Square and Fisher's Exact Test. Several risk factors that were found significant in univariate analysis, such as personal and family history of atopic disease, and positive SPTs and IDTs were examined with multiple logistic regression analysis to see if they were related to a higher risk for a positive DPT. Results Semi-synthetic penicillin was the most common group of antibiotics thought to cause allergic reactions in this study. Overall, 123 children with a personal history of an adverse reaction to a certain antibiotic, were evaluated. In 87.8% of the cases, the symptoms had occurred several hours after administration of the culprit antibiotic. Both SPTs and IDTs had low sensitivity but high specificity. Moreover, they had a high positive predictive value (PPV). In contrast, eosinophilia was not recognized as a risk factor. Seventeen patients (13.8%) had a true antibiotic allergy, as confirmed by a positive DPT. A positive IDT was a strong predictor of a positive DPT, along with a positive personal and family history of atopy. Conclusion SPTs and IDTs are very reliable in confirming antibiotic allergy when found positive. A negative result of a SPT highly predicts a negative DPT. A positive IDT and a positive personal and family history of atopy were recognized as significant risk factors for antibiotic allergy.

Chinese Guideline on Allergen Immunotherapy for Allergic Rhinitis: The 2022 Update. ALLERGY, ASTHMA & IMMUNOLOGY RESEARCH 2022; 14:604-652.

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.

Abstract
Anaphylaxis is a severe allergic reaction that requires immediate recognition and intervention. This study investigated the factors related to the timely administration of epinephrine in cases of pediatric anaphylaxis. We performed a retrospective chart review of 107 patients who visited a pediatric emergency center with anaphylaxis between 2015 and 2017. In total, 76 patients received epinephrine injections. We analyzed factors including allergy history, anaphylaxis signs and symptoms, allergen sensitization, anaphylaxis triggers, and time of epinephrine injection. Anaphylactic patients who received epinephrine took a median of 50 min to arrive at the hospital, and patients who did not receive epinephrine took a median of 94 min. Epinephrine administration was significantly delayed by more than 60 min from symptom onset in patients <2 years old. Patients presenting with wheezing symptoms or history of bronchial asthma were significantly more likely to receive epinephrine within 60 min of symptoms onset, while patients with food allergen sensitization were significantly more likely to receive epinephrine within 30 min of hospital arrival. Wheezing, history of asthma, age (≥2 years old), food triggers, and food allergen sensitivity were significant factors for the rapid administration of epinephrine. An immediate diagnosis of anaphylaxis and a rapid administration of epinephrine are essential.

Abstract
Aims: Allergen immunotherapy aims to induce tolerance, which persists after its discontinuation, to targeted allergens. However, concern exists regarding the use of subcutaneous immunotherapy with whole extracts due to frequently reported events of anaphylactic reactions. Materials & methods: In this pharmacovigilance study, the authors assessed the safety of subcutaneous immunotherapy with the monomeric allergoid Lais-in using a database of adverse reactions documented in real-world postmarketing reports from 2010 to 2020. Results & conclusion: The results showed that more than 171,916 doses of Lais-in were administered from 2010 to 2020, resulting in five adverse drug reactions. Nonserious adverse events, including hives, eye irritation and skin reactions, were reported. These data indicate that monomeric allergoids prevent serious reactions to subcutaneous immunotherapy.

ALLERGY, ASTHMA, AND CLINICAL IMMUNOLOGY : OFFICIAL JOURNAL OF THE CANADIAN SOCIETY OF ALLERGY AND CLINICAL IMMUNOLOGY 2022; 18:61. [PMID: 35791000 PMCID: PMC9254488 DOI: 10.1186/s13223-022-00702-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Accepted: 06/27/2022] [Indexed: 11/29/2022]
Abstract
Background Wheat-dependent exercise-induced anaphylaxis (WDEIA) is a serious and potentially life-threatening form of wheat allergy. Further episodes can only be prevented by avoiding wheat ingestion or avoiding exercise after wheat intake. Anaphylaxis may recur in some patients post-diagnosis. This study aimed to analyze the clinical features and management/outcomes of WDEIA in China. Methods We retrospectively analyzed the clinical characteristics, and laboratory testing of 197 patients with WDEIA. After diagnosis, the patients were followed up as outpatients to evaluate dietary/exercise choice and clinical outcomes. Results Among the 197 WDEIA patients (median age, 37 years), 53.8% were male and 28.4% had other allergic disorders. The median duration of anaphylaxis before diagnosis was 16 months. Significant delays in diagnosis (> 1 years) were recorded in 52.7% of the patients, which has not decreased by years (P = 0.064). Exercise (83.8%), alcohol (12.2%), and nonsteroidal anti-inflammatory drugs (7.1%) were the most common cofactors. The most common clinical features were urticaria (100%), loss of consciousness (82.7%), dyspnea (50.8%), and hypotension (47.2%). Of the 197 eligible patients, 155 responded (78.7%), and 124 (80.0%) of which had no anaphylaxis post-diagnosis. A wheat-free diet prevented future anaphylaxis in 91.7% of the patients, followed by the avoidance of wheat combined with exercise (87%) and reduced wheat intake combined with exercise avoidance (80.5%). Conclusion The diagnosis of WDEIA is frequently delayed. Therefore, when patients present with unexplained anaphylaxis, the possibility of WDEIA should be considered. A wheat-free diet or avoiding wheat combined with exercise or reduced wheat combined with exercise avoidance helps to significantly reduce the onset of future anaphylaxis. However, approximately one-fifth of patients continue to experience anaphylaxis post-diagnosis. Thus, these patients must always carry epinephrine autoinjectors.

Abstract
BACKGROUND Immunotherapy is promising as an efficacious treatment for food allergy. Other food allergy treatments are also under development. However, adverse allergic events during treatment, as well as during oral food challenges, are common and reporting is not standardized. OBJECTIVE A more nuanced grading scale is needed to create a comprehensive and universal system to categorize adverse events and their severity for food allergy clinical trials. METHODS Starting with the 2012 Consortium for Food Allergy Research (CoFAR) Grading Scale and the World Allergy Organization Grading System, we developed the CoFAR Grading Scale for Systemic Allergic Reactions, Version 3.0, in collaboration with industry partners with expert opinion. RESULTS The revised CoFAR Grading Scale for Systemic Allergic Reactions has 5 levels of increasing severity, ranging from generalized urticaria, localized angioedema, rhinitis, and abdominal pain (grade 1) to death (grade 5). Systemic reactions are further categorized within each grade by relevant organ system. Mild, single-system reactions are differentiated from mild, multisystem reactions. Lower respiratory tract symptoms are graded on the basis of response to therapy; those that are refractory to standard treatment (eg, requiring >3 doses of intramuscular epinephrine, continuous intravenous epinephrine infusion, and continuous albuterol nebulization) and respiratory compromise requiring mechanical ventilation are classified as grade 4, life-threatening reactions. CONCLUSIONS Universal and consistent use of the revised CoFAR Grading Scale beyond the CoFAR centers would allow for better data aggregation and safety comparisons in clinical trials for food allergy.

Abstract
BACKGROUND The heterogeneity and lack of validation of existing severity scores for food allergic reactions limit standardization of case management and research advances. We aimed to develop and validate a severity score for food allergic reactions. METHODS Following a multidisciplinary experts consensus, it was decided to develop a food allergy severity score (FASS) with ordinal (oFASS) and numerical (nFASS) formats. oFASS with 3 and 5 grades were generated through expert consensus, and nFASS by mathematical modeling. Evaluation was performed in the EuroPrevall outpatient clinic cohort (8232 food reactions) by logistic regression with request of emergency care and medications used as outcomes. Discrimination, classification, and calibration were calculated. Bootstrapping internal validation was followed by external validation (logistic regression) in 5 cohorts (3622 food reactions). Correlation of nFASS with the severity classification done by expert allergy clinicians by Best-Worst Scaling of 32 food reactions was calculated. RESULTS oFASS and nFASS map consistently, with nFASS having greater granularity. With the outcomes emergency care, adrenaline and critical medical treatment, oFASS and nFASS had a good discrimination (receiver operating characteristic area under the curve [ROC-AUC]>0.80), classification (sensitivity 0.87-0.92, specificity 0.73-0.78), and calibration. Bootstrapping over ROC-AUC showed negligible biases (1.0 × 10-6 -1.23 × 10-3 ). In external validation, nFASS performed best with higher ROC-AUC. nFASS was strongly correlated (R 0.89) to best-worst scoring of 334 expert clinicians. CONCLUSION FASS is a validated and reliable method to measure severity of food allergic reactions. The ordinal and numerical versions that map onto each other are suitable for use by different stakeholders in different settings.

Abstract
Viral infections increase the risk of developing allergies in childhood, and disruption of mucosal homeostasis is presumed to be involved. However, no study has reported a role for viral infections in such disruption. In this study, we clarified the mechanism of immunoglobulin A (IgA) overproduction in viral infections. Autopsies were performed on 33 pediatric cases, IgA and interferon (IFN)β levels were measured, and histopathological and immunohistochemical examinations were conducted. Furthermore, we cultured human cells and measured IFNβ and IgA levels to examine the effect of viral infections on IgA production. Blood IgA levels in viral infections were higher than in bacterial infections. Moreover, IFNβ levels in most viral cases were below the detection limit. Cell culture revealed increased IgA in gastrointestinal lymph nodes, especially in Peyer’s patches, due to enhanced IFNβ after viral stimulation. Conversely, respiratory regional lymph nodes showed enhanced IgA with no marked change in IFNβ. Overproduction of IgA, identified as an aberration of the immune system and resulting from excessive viral infection-induced IFNβ was observed in the intestinal regional lymph nodes, particularly in Peyer’s patches. Further, increased IgA without elevated IFNβ in the respiratory system suggested the possibility of a different mechanism from the gastrointestinal system.

Abstract
Anaphylaxis is a systemic allergic reaction that can be caused by food, drugs, insect bites, or unknown triggers in infants and toddlers. Anaphylaxis rates are increasing. Infants and toddlers may have increased exposure to known and unknown allergens, decreased ability to describe their symptoms, and an expanded differential diagnosis for consideration on presentation. The most common symptoms in these age groups are cutaneous and gastrointestinal. Age-specific language may be helpful for caregivers to identify and describe the symptoms of anaphylaxis in infants and toddlers. Long-term management of anaphylaxis includes allergy evaluation to guide avoidance and assess prognosis and education on allergic reaction management; this incorporates the prescription of epinephrine autoinjector and provision of an allergy emergency plan.

Abstract
Epinephrine is a lifesaving medication to treat systemic allergic reactions including anaphylaxis. Epinephrine autoinjectors (EAIs) are expensive, not available everywhere in the world, and shortages can limit their access. Epinephrine prefilled syringes and epinephrine kits are lower-cost alternatives to EAIs. Advantages, disadvantages, and costs of available products are discussed and the socioeconomic factors impacting access to EAIs described. EAIs designed for infants also are discussed.

Abstract
There are many definitions of anaphylaxis in the medical literature. The authors propose a modified definition of anaphylaxis to be used for clinical decision making that promotes the early utilization of intramuscular epinephrine. Anaphylaxis can be a result of an allergic or nonallergic mechanism. In general, allergic reactions are more severe; however, any type of anaphylaxis can result in death and improve with IM epinephrine. The World Allergy Organization's Grading Criteria for allergic systemic reactions are adapted as a guide to identify manifestations that may progress to anaphylaxis. The intent is to promote and encourage the use of IM epinephrine in the health care setting before the progression of manifestations and the onset of life-threatening respiratory or cardiovascular dysfunction generally recognized as meeting the definition of anaphylaxis.

Abstract
Delayed administration of epinephrine (adrenaline), the first-line and only effective treatment of a systemic allergic reaction (SAR) and anaphylaxis, is associated with increased mortality. However, epinephrine is underused because of a lack of consensus as to when it should be administered and an inappropriate fear of using epinephrine and potential adverse effects from the medication. The authors emphasize that SARs and anaphylaxis should be considered as a spectrum, and that affected individuals be educated on its safety and repeatedly given instructions as to when and how epinephrine should be used at the first symptoms or signs of SAR and anaphylaxis.

Abstract
There are significant anaphylaxis data and knowledge gaps that result in suboptimal patient care and outcomes. To address these gaps there is need for collaborative, multidisciplinary research networks to strategically design practice changing research specific to the following anaphylaxis themes: Population Science, Basic and Translational Sciences, Acute Management, and Long-Term Management. Top priorities are to refine anaphylaxis diagnostic criteria, identify accurate diagnostic and predictive anaphylaxis biomarkers, standardize postanaphylaxis care (observation periods, hospitalization criteria), and determine immunotherapy best practices. Addressing these gaps will result in improved, optimal care and clinical outcomes for patients with or at risk of anaphylaxis.

Abstract
BACKGROUND The prevalence of sesame food allergy (SFA) is increasing worldwide with the potential of anaphylactic reactions upon exposure. Utility of specific component IgE testing as an alternative to the oral food challenge (OFC), the diagnostic standard, is being investigated. METHODS Patients (n = 42) with suspected SFA completed an open OFC to sesame. Diagnostic testing included serum levels of Ses i 1-specific IgE, skin prick test with high-protein extract, and basophil reactivity (% induced CD63 expression) for each patient. The diagnostic utility of these tests was evaluated at a 95% sensitivity, with the outcome measure being the number of OFCs required. RESULTS Twenty-seven patients (64%) were diagnosed with SFA. Ses i 1 IgE differed significantly between allergic and tolerant patients (p = .0001). ROC curve analysis for Ses i 1 IgE yielded an AUC of 0.88 ± 0.05. Levels of Ses i 1 IgE correlated to induced CD63+ expression on basophils (p = .0001). Ses i 1 IgE was not sufficiently robust as a single step for diagnosis. Used concurrently, BAT and Ses i 1 IgE yielded correct positive classifications for 25 of 27 sesame-allergic patients with two false positives (93% PPV). Both tests were negative in 5 non-allergic patients. Patients with divergent Ses i 1 IgE and BAT results required OFC (n = 10, 24% of patients). Alternatively, sequential use of BAT, ruling in SFA followed by Ses i 1 IgE diagnosing non-allergic patients, yielded a 89% PPV, with 19% requiring OFC. CONCLUSION Ses i 1 IgE and BAT used together can decrease the need for OFC in most SFA patients. A prospective cohort trial is necessary to validate these results.

Abstract
INTRODUCTION The number of anaphylaxis diagnoses in children is rising, being still based on the clinical picture. AIM To determine whether triggers of anaphylaxis influence its clinical characteristics in children and adolescents. MATERIAL AND METHODS The study group included 114 children (5 months-17 years, mean age: 8.0 ±4.8 years), (66%: boys) with the episode of anaphylaxis up to 1 year back. Medical data were entered to the NORA Registry by means of a validated structured on-line questionnaire. RESULTS Three most frequent triggers of anaphylaxis were: insect venom (47.4%), food (35.1%), drugs (5.3%), with a predominance of food (egg white, cow's milk, nuts and peanuts) in the 0-6 years age group, while insect venom (bee predominance) in the 7-17 years age group (p = 0.016). Clinical manifestations differed between food vs. venom allergic reactions and presented as gastro-intestinal (GI) (61.4%) (p = 0.004), respiratory (RS) (93.9%) (p = 0.036), and cardiovascular (CVS) (74.6%) (p = 0.022) symptoms. Among objective symptoms, vomiting was the most common symptom in the 0-2 years age group (47.1%) (p = 0.006), while hypotension in those aged 7-12 years (40%) (p = 0.010). Severity of symptoms evaluated as Mueller's grade (IV - 74.5%) and as Ring and Messmer's grade (III - 65.8%), depended on the trigger (p = 0.028, p = 0.029, respectively). Life-threatening symptoms occurred in 26 children (fall of the blood pressure - 22%, loss of consciousness - 4.4%). CONCLUSIONS The clinical manifestation of anaphylaxis in children is both trigger and age dependent, irrespective of the gender. A typical patient with food anaphylaxis was younger, presenting predominantly GI symptoms, while a typical patient with venom anaphylaxis was older, with mostly cardiovascular symptoms.

Abstract
PURPOSE OF REVIEW The purpose of the review is to identify unmet needs in the management of anaphylaxis, covering aspects such as epidemiology, diagnosis, treatment and prevention. RECENT FINDINGS Redefinition of clinical diagnostic criteria may allow a better identification of anaphylaxis. International diagnostic coding system improvement will be major step for future policies and epidemiological studies. Digital health can aid in managing anaphylaxis. SUMMARY Anaphylaxis is a medical emergency; current data show that frequently identification of the reaction, acute and long-term management, are not optimal. Therefore, there is a need to implement strategies to improve the situation. This review has identified unmet needs in anaphylaxis regarding aspects such as epidemiology, severity scoring, definition and diagnostic criteria, anaphylaxis in infants and toddlers, cofactors, biomarkers, long-term management, undertreatment and availability of epinephrine autoinjectors. Strategies focused on education, legislation, digital health and research are proposed.

Abstract
Objectives: The study's primary objective will be to evaluate the safety and describe the initial experience of implementing early discharge (on the same day) of coronary patients from the Unified Health System undergoing elective, uncomplicated, transradial percutaneous coronary intervention. The secondary objective will be to assess the impact on the direct cost per patient compared to previously known data from the classic hospital stay used (hospital overnight). Methods: Observational and prospective study of patients undergoing elective uncomplicated transradial percutaneous coronary intervention with early discharge, respecting the inclusion and exclusion criteria. Follow-up of patients will be carried out to prove the safety of the new strategy in the population of the Unified Health System and to compare the direct costs between overnight stays and discharge on the same day. This will be the first study dedicated to primarily evaluating the safety of early discharge after elective uncomplicated transradial coronary angioplasty, validating this protocol in the population of the Brazilian public health system.

Abstract
BACKGROUND Limited information is known on adverse events and efficacy associated with venomous insect immunotherapy (VIT) in canine patients. OBJECTIVES To assess adverse events associated with VIT and perceived efficacy of VIT. ANIMALS Records from 82 client-owned animals which received VIT were assessed. METHODS AND MATERIALS A retrospective review of records from 2002 to 2020. Clinical history, adverse events during therapy and observations following field stings were collected from all records. Patients were grouped into reactors and nonreactors based on whether or not an adverse event had occurred during therapy. Records were evaluated to determine if a field sting had occurred and the severity of the reaction was compared to pretreatment reaction. RESULTS Of 82 patients that were identified, 26 experienced a minimum of one adverse event. No deaths or severe anaphylactic reactions were reported. The most common adverse event was gastrointestinal upset. The overall reaction rate per injection was 2.8%. Only variation in sensitisation level (the minimum concentration of venom which elicited a positive intradermal reaction) was significantly different between groups (P = 0.014). Forty-one field challenges in 26 patients were documented. Therapy reduced the severity of reactions in 87.8% of challenges. No deaths were reported. CONCLUSION Venom immunotherapy appears to be a safe and efficacious treatment for prevention of anaphylaxis due to insect stings in canine patients.

Kennedy K, Alfaro MKC, Spergel ZC, Dorris SL, Spergel JM, Capucilli P. Differences in oral food challenge reaction severity based on increasing age in a pediatric population. Ann Allergy Asthma Immunol 2021; 127:562-567.e1. [PMID: 34010700 DOI: 10.1016/j.anai.2021.05.013] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2021] [Revised: 04/16/2021] [Accepted: 05/07/2021] [Indexed: 01/27/2023]
Abstract
BACKGROUND Food allergy reactions range from mild to severe with differences in age appearing to be an important factor associated with reaction severity. OBJECTIVE To define differences in oral food challenge (OFC) reaction severity in pediatric patients from infancy to adolescence using objective clinical outcomes and standardized reaction grading tools. METHODS Retrospective review of all positive OFC results at 2 large institutions between September 2016 and February 2019. Reaction severity was defined by presence of cardiovascular, neurologic, lower respiratory, or laryngeal symptoms, epinephrine requirement, and grading using 2 established food allergy reaction scales. RESULTS Infants and toddlers had fewer reactions involving cardiovascular, neurologic, lower respiratory, or laryngeal symptoms compared with older age groups. Epinephrine was also required less frequently during reactions in infants and toddlers, compared with older age groups. There was no difference in reaction severity in infants and toddlers based on clinical history of eczema. Increasing age was significantly correlated with increased epinephrine requirement (R2 = 0.12, P = .002), elevated Consortium of Food Allergy Research score (R2 = .012, P = .003), and approached significance for increased Practical Allergy score (R2 = .005, P = .05). History of asthma and sesame allergy were identified to be positively correlated with more severe reactions. CONCLUSION Infants and young toddlers have less severe reactions during OFCs compared with older age groups supporting early food introduction practices. In children under 12 months of age, severe reactions are most rare calling into question screening practices using specific allergy testing before food introduction. Standardized reaction grading tools may be valuable instruments to categorize reaction severity during OFCs.

A severity grading system of food-induced acute allergic reactions to avoid the delay of epinephrine administration. Ann Allergy Asthma Immunol 2021; 127:462-470.e2. [PMID: 33895419 DOI: 10.1016/j.anai.2021.04.015] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 03/11/2021] [Accepted: 04/16/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Substantial discrepancies among anaphylaxis severity scores may delay epinephrine administration. OBJECTIVE The study aims to develop a transparent severity grading system of food-induced acute allergic reactions with a decision model for epinephrine use. METHODS The natural course of 315 acute food-induced allergic reactions in children hospitalized at the Allergology department between May 2016 and July 2019 owing to follow-up treatment and allergy diagnostics was evaluated. The severity of episodes was classified according to the 5 most accepted grading systems. The interrater reliability of classification between anaphylaxis severity scores was assessed. All symptoms were grouped into a heat map according to their real-life incidence and clinical relevance. Based on the heat map analysis, a severity grading system of food-induced acute allergic reactions in children with the epinephrine administration decision model was created. RESULTS Data from 259 food-induced anaphylaxis episodes in 157 children were included in the analysis. Comparing the grading systems, we observed a 24.7% to 70.2% disagreement between severity scores. The heat map illustrated a strong association between 29 symptoms and their categorization. A new severity grading system was developed and a 2-stage decision model was proposed: "epinephrine yes" (any rapidly progressing symptoms, even mild ones or from 1 organ system; any symptoms from more than 1 organ system; or every grade of anaphylaxis), and "epinephrine available and prepared to use" (nonprogressing mild systemic allergic reaction from 1 system area only; no anaphylaxis). CONCLUSION A new severity grading system of food-induced acute allergic reactions in children could serve as a clinical tool for health care professionals to avoid epinephrine administration delay.

Abstract
Background Allergen immunotherapy (AIT) is the only causal therapy for IgE-mediated allergy. There is less evidence about the safety and efficacy of AIT especially subcutaneous immunotherapy (SCIT) in children under 5 years old. We aimed to investigate the side effects and associated risk factors of house dust mite (HDM) SCIT in preschool children with respiratory allergic diseases. Methods The preschool children who had HDM-related allergic rhinitis with/without asthma were enrolled and undergone standardized HDM SCIT in our department from June 2013 to December 2019. Local reactions (LRs) and systemic reactions (SRs) were recorded and categorized according to World Allergy Organization recommendations. Demographic data and other therapeutic-related parameters were also recorded to investigate potential risk factors for these side effects. Results A total of 91 children (60 boys, 65.93%; 31 girls, 34.07%; mean age 4.13 years old) were included in the study. Among the 91 patients, 3109 SCIT injections were recorded, 62/91 (68.13%) experienced 186 immediate LRs, 4 /91(4.40%) experienced 6 delayed LRs, 11/91 (12.09%) children experienced 44 immediate SRs, 21/44 (47.73%) were grade 1 SRs, 21/44 (47.73%) were grade 2, 2/44 (4.55%) were grade 3, no grade 4 or 5 SRs occurred. Furthermore, 1/91 (1.10%) experienced 1 delayed SRs, manifested by urticaria 2 days later after allergen injection. 9/91 (9.89%) experienced 2 or more times SRs. Multivariable logistic regression analysis showed BMI (OR 1.506; 95%CI 1.091 to 2.079; p < 0.05) and sIgE against HDM (OR 1.497; 95%CI 1.082 to 2.071; p < 0.05) were risk factors for LRs. No variable was found to correlate with SRs (all p > 0.05). Conclusions HDM subcutaneous immunotherapy is considered to be safe in preschool children with respiratory allergic diseases. Higher BMI and HDM sIgE level in children are risk factors for developing LRs. The incidence of SRs and the rate of severe SRs are low in preschool children.

Abstract
Objectives: The primary objective of this study will be to evaluate the efficacy of subcutaneous and peri-arterial isosorbide mononitrate in preventing occlusion of the radial artery (ORA) after percutaneous coronary procedures (PCP) performed by the transradial approach (TRA). As secondary objectives, define the incidence of ORA in the institution and assess variables related to the risk of occlusion. Methods: Single-center, double-blind, randomized study, including in- and outpatients from a high complexity hospital, admitted to performing PCP, diagnostic or therapeutic, by TRA, in stable coronary conditions (elective) or acute coronary syndrome. The sample will be randomly divided into a group that will receive the medication and a control group. All participants will be submitted to palpatory assessment of radial artery patency and the Barbeau inverse test within 24 h and seven days after the procedure. This will be the first study to evaluate isosorbide mononitrate as an accessible and inexpensive pharmacological method for preventing OAR after PCP by VTR.

Abstract
BACKGROUND AND AIMS The term "Food Allergy" refers to a complex global health problem with a wide spectrum of severity. However, a uniform definition of severe food allergy is currently missing. This systematic review is the preliminary step towards a state-of-the-art synopsis of the current evidence relating to the severity of IgE-mediated food allergy; it will inform attempts to develop a consensus to define food allergy severity by clinicians and other stakeholders. METHODS We undertook a mixed-methods systematic review, which involved searching 11 international biomedical databases for published studies from inception to 31 December 2019. Studies were independently screened against pre-defined eligibility criteria and critically appraised by established instruments. The substantial heterogeneity of included studies precluded meta-analyses and, therefore, narrative synthesis of quantitative and qualitative data was performed. RESULTS We found 23 studies providing eligible primary data on symptom-specific severity of food allergic reactions, and 31 previously published symptom-severity scoring systems referred to food allergic reactions. There were seven studies which assessed quality-of-life measures in patients (and family members) with different food allergy severity and two studies that investigated the economic burden of food allergy severity. Overall, the quality and the global rating of all included studies were judged as being moderate. CONCLUSIONS There is heterogeneity among severity scoring systems used and even outcomes considered in the context of severity of food allergy. No score has been validated. Our results will be used to inform the development of an international consensus to define the severity of food allergy. SYSTEMATIC REVIEW REGISTRATION A protocol was prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO) database with the registration number CRD42020183103 (https://www.crd.york.ac.uk/prospero/#recordDetails).

Abstract
INTRODUCTION Subcutaneous allergen-specific immunotherapy (SCIT) is one of the main cornerstones in the treatment of allergic rhinitis in pediatric patients. It has demonstrated symptoms and quality of life improvement, but it is not exempt from adverse reactions (ADVrs). Nevertheless, there are a few reports that have evaluated their safety. Our objective was to evaluate the ADVr to SCIT in pediatric patients. METHODS We reviewed 786 clinical records with SCIT from 2005 to 2018, comparing the clinical characteristics of patients with ADVrs with SCIT versus a group of a similar number of patients who completed SCIT (control group, CG). The analysis of ADVrs was according to the World Allergy Organization (WAO) 2010 grading system by frequency analysis, survival curve, and log rank. RESULTS Of 786 patients, 106 (13.4%) presented ADVrs, and the patients with ADVr had sensitivity and immunotherapy with at least 2 allergens versus CG p < 0.001, containing a combination of standardized and nonstandardized allergens (p = 0.003). The ADVrs were in the buildup phase (p < 0.001). The survival curve showed that 50% had some reaction at 12 weeks of SCIT. The most frequent ADVr was grade 1 in 73/106 patients (68.8%) and grade 2 in 33/106 (31.1%). The log-rank analysis between the grades of the WAO grading system showed a statistically significant difference (p = 0.02). CONCLUSIONS The SCIT is safe in pediatric patients. The ADVrs are infrequent, grade 1 being the most reported; however, at >12 weeks, the risk of ADVrs that involve 2 organs systems increases.

Abstract
BACKGROUND There is no widely adopted severity grading system for acute allergic reactions, including anaphylactic and nonanaphylactic reactions, thus limiting the ability to optimize and standardize management practices and advance research. OBJECTIVE The aim of this study was to develop a severity grading system for acute allergic reactions for use in clinical care and research. METHODS From May to September 2020, we convened a 21-member multidisciplinary panel of allergy and emergency care experts; 9 members formed a writing group to critically appraise and assess the strengths and limitations of prior severity grading systems and develop the structure and content for an optimal severity grading system. The entire study panel then revised the grading system and sought consensus by utilizing Delphi methodology. RESULTS The writing group recommended that an optimal grading system encompass the severity of acute allergic reactions on a continuum from mild allergic reactions to anaphylactic shock. Additionally, the severity grading system must be able to discriminate between clinically important differences in reaction severity to be relevant in research while also being intuitive and straightforward to apply in clinical care. Consensus was reached for all elements of the proposed severity grading system. CONCLUSION We developed a consensus severity grading system for acute allergic reactions, including anaphylactic and nonanaphylactic reactions. Successful international validation, refinement, dissemination, and application of the grading system will improve communication among providers and patients about the severity of allergic reactions and will help advance future research.

Abstract
BACKGROUND There have been no reports of treatment effect persistence after long-term sublingual immunotherapy (SLIT) in patients with Japanese cedar (JC) pollinosis. Therefore, we conducted a post-marketing clinical trial to investigate the efficacy, safety, and effect persistence of JC pollen SLIT drops after approximately 3 years of treatment. METHODS This was an open-label trial of 233 patients with JC pollinosis who were treated with JC pollen SLIT drops for approximately 3 years (2015-2017) and followed-up for an additional 2 years (2018-2019). Efficacy and effect persistence were evaluated using nasal and ocular symptom scores, daily use of rescue medication, and Japanese Rhinoconjunctivitis Quality of Life Questionnaire scores recorded during the JC pollen dispersal season of each year. Safety was evaluated by monitoring adverse events and adverse drug reactions. RESULTS The mean combined total nasal symptom and medication score (range 0-18) during the peak symptom periods of 2015 through 2019 were 5.47 ± 3.38, 4.52 ± 3.13, 3.58 ± 2.63, 5.28 ± 4.01, and 6.83 ± 4.65, respectively. The percentage of patients who used no rescue medications during the same periods was 64.8%, 75.2%, 80.3%, 63.7%, and 50.3%, respectively. A total of 138 adverse drug reaction incidents were recorded in 73 of the 233 patients (31.3%), of which 134 incidents (97.1%) were mild in severity. CONCLUSIONS JC pollen SLIT drops demonstrated treatment duration-dependent efficacy with effects that persisted for 2 years after cessation of treatment. The drug had a favorable safety profile over the 5-year study period.

Abstract
Anaphylaxis is the most severe clinical presentation of acute systemic allergic reactions. The occurrence of anaphylaxis has increased in recent years, and subsequently, there is a need to continue disseminating knowledge on the diagnosis and management, so every healthcare professional is prepared to deal with such emergencies. The rationale of this updated position document is the need to keep guidance aligned with the current state of the art of knowledge in anaphylaxis management. The World Allergy Organization (WAO) anaphylaxis guidelines were published in 2011, and the current guidance adopts their major indications, incorporating some novel changes. Intramuscular epinephrine (adrenaline) continues to be the first-line treatment for anaphylaxis. Nevertheless, its use remains suboptimal. After an anaphylaxis occurrence, patients should be referred to a specialist to assess the potential cause and to be educated on prevention of recurrences and self-management. The limited availability of epinephrine auto-injectors remains a major problem in many countries, as well as their affordability for some patients.
