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.

International guidelines for the treatment of chronic spontaneous urticaria support the updosing of second-generation antihistamines to four times of the approved dose when adequate symptom control cannot be achieved with the standard dosage. However, this recommendation is primarily based on expert opinions, and there is a lack of large, well-designed, double-blind clinical trials. Most the existing trials provide insufficient data, and due to the heterogeneity of the conducted trials on antihistamine effects (definition of control, design, quality, lack of an active comparator, no placebo arm, small sample size, outcomes) and their short duration, comparative analysis is challenging.

Introduction: Chronic urticaria (CU), including chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU), is a prevalent, enduring, mast-cell driven condition that presents challenges in its management. There is a clear need for additional approved treatment options beyond H1 receptor antagonists and the anti-IgE monoclonal antibody (mAb), omalizumab. One of the latest therapeutic strategies targets KIT, which is considered the primary master regulator for mast cell-related disorders.

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.

Our knowledge about the role of viral infection and vaccination in acute and chronic urticaria improved as a result of the COVID-19 pandemic but it has also highlighted knowledge gaps. Viral infections, especially respiratory tract infections like COVID-19, can trigger the onset of acute urticaria (AU) and the exacerbation of chronic urticaria (CU).

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).
Introduction: Allergic diseases represent a broad spectrum of high-prevalence, chronic conditions that remain underdiagnosed and undertreated. The aims of this interdisciplinary, questionnaire-based, non-interventional study were to identify and analyze potential barriers to clinical allergological care in Germany.
Methods: All hospitals listed in the German hospital register involved in the treatment of allergological patients (n = 899) were invited to participate.
This publication is the second part of the German-language S3 guideline on urticaria. It covers the management of urticaria and should be used together with Part 1 of the guideline on classification and diagnosis. This publication was prepared according to the criteria of the AWMF on the basis of the international English-language S3 guideline with special consideration of health system conditions in German-speaking countries.

Data on long-term effectiveness and predictive factors for treatment response are currently limited. In this monocentric, prospective, observational study, 112 patients with chronic spontaneous urticaria (CSU) and 32 patients with chronic inducible urticaria (CIndU) were included.
