Heat Treatment of Hazelnut Allergens Monitored by Polyclonal Sera and Epitope Fingerprinting.

Hazelnuts are frequently involved in IgE-mediated reactions and are the main cause of nut allergies in Europe. Most food products are processed before human consumption. Food processing can modify the structure, properties, and function of proteins, and as a result, the IgE-binding capacity of allergens can be affected.

Occupational anaphylaxis: A Position Paper of the German Society of Allergology and Clinical Immunology (DGAKI).

Background: Anaphylaxis is a systemic allergic reaction that is potentially life-threatening. Occupational anaphylaxis is an anaphylaxis that occurs in an occupational context. In this position paper, we propose diagnostic criteria for occupational anaphylaxis and provide an overview of the current state of knowledge in terms of prevalence, triggers, prevention, and management.

Disease modification in chronic spontaneous urticaria.

Chronic spontaneous urticaria (CSU) is a debilitating, inflammatory skin condition characterized by infiltrating immune cells. Available treatments are limited to improving the signs and symptoms. There is an unmet need to develop therapies that target disease-driving pathways upstream of mast cell activation to inhibit or delay the progression of CSU and associated comorbidities.

Rapid response to dupilumab in an adult patient with eosinophilic esophagitis and allergic asthma.

Background: Eosinophilic esophagitis (EoE) is an inflammatory disease of the esophagus that belongs to the spectrum of Th2-mediated diseases. It is often associated with atopic comorbidities such as allergic asthma (AA) and poses a therapeutic challenge.

Case Report: We report on a 43-year-old patient with EoE and AA who did not show sufficient therapeutic control despite standard therapy.

Emerging and Novel Elicitors of Anaphylaxis: Collegium Internationale Allergologicum Update 2024.

Background: Anaphylaxis represents the most severe end of the spectrum of allergic reactions. Frequent elicitors of anaphylaxis are insects, foods, and drugs. This paper summarizes recent development with regard to emerging and novel elicitors of anaphylaxis.

[Which augmentation and trigger factors are relevant in urticaria?].

The aim of this review is to present relevant trigger as well as augmentation factors that can induce or exacerbate urticaria on the basis of a current, PubMed-based literature search. In addition to a brief description of relevant influencing factors in acute and chronic inducible urticaria, the focus will be on chronic spontaneous urticaria. In particular, the aggravating role of medication, stress, food, psychological and metabolic comorbidities, infections and inflammation as well as hormonal processes will be discussed.

Occupational anaphylaxis-Data from the anaphylaxis registry.

Background: Epidemiologic data on occupational anaphylaxis is scarce, and there is a need of more knowledge about work-related anaphylactic episodes.

Methods: Based on the data of the Anaphylaxis Registry, we identified cases related to occupational exposure and analyzed the elicitors, demographics, severity of clinical reaction and management.

Results: Since 2017, 5851 cases with an information about the occupational relation of the anaphylactic episode were registered whereby 225 (3.

Fatal and Near-Fatal Anaphylaxis: Data From the European Anaphylaxis Registry and National Health Statistics.

Background: Anaphylaxis is a serious systemic reaction-data on fatal and near-fatal reactions are limited.

Objective: To better understand clinical patterns and risks factors of severe anaphylaxis by a deep analysis of data from fatal and near-fatal anaphylaxis.

Methods: Data from the European Anaphylaxis Registry on fatal/near-fatal anaphylactic reactions and national data on anaphylaxis fatalities were investigated.

Food allergy - New risks through vegan diet? Overview of new allergen sources and current data on the potential risk of anaphylaxis.

A vegan diet is increasingly en vogue, i.e., a diet based on plants, in which animal products are completely avoided, often for health and environmental reasons.

Current situation of allergological health care at German hospitals.

Background: Allergic medical care in Germany is organized on an interdisciplinary basis. An overview of the current care situation is necessary to manage and improve interdisciplinary cooperation.

Methods: Between January and February 2022, questionnaires were sent online and by mail to chief physicians of inpatient clinical departments to which most allergological diseases are assigned (dermatology, otorhinolaryngology [ENT], pulmonology, pediatrics, environmental/occupational medicine, gastroenterology; n = 899).

Contact allergy to ingredients of hair cosmetics in female hairdressers and female consumers-An update based on IVDK data 2013-2020.

Background: Hair cosmetic products contain several, partly potent contact allergens, including excipients like preservatives. Hand dermatitis in hairdressers is common, scalp and face dermatitis in clients or self-users (summarised here as 'consumers') may be severe.

Objective: To compare frequencies of sensitization to hair cosmetic ingredients and other selected allergens between female patch tested patients working as hairdressers and consumers without professional background, respectively, who were tested for suspected allergic contact dermatitis to such products.

Developments and perspectives in allergology.

Allergology is a key part of dermatological care. This paper reviews current pathophysiological, diagnostic and therapeutic developments in immediate-type allergies. Type-2 inflammation is involved in several allergological diseases such as allergic rhinitis and asthma.

Vegan diets from an allergy point of view - Position paper of the DGAKI working group on food allergy.

Vegan diets are currently attracting a great deal of attention. However, avoiding animal-based foods restricts the diet and is associated with risks, the extent and medical implications of which are at present not sufficiently understood. Elimination diets represent the usual therapeutic long-term management in the presence of food allergy.
