The Severity of Allergic Reactions in a Real-World Environment Is Independent of the Eliciting Amounts of Foods.

Introduction: Patients with food allergies need personalized information on their risk of reaction in "real-life" situations. This multicentric study aimed to investigate the link during accidental reactions between the nature and amount of food allergens consumed in "real-life situation" and the severity of the symptoms.

Methods: Patients were prospectively recruited from December 1, 2020, to December 31, 2021, at the emergency departments in the Geneva University Hospitals and local pediatric emergency facilities, through an allergy outpatient clinic, at school and daycare facilities and trough their primary care physicians.

Working with companies that manufacture breastmilk substitutes: An EAACI position paper.

Breastmilk is the optimal source of nutrition for infants and should ideally be provided exclusively for the first 6 months of life, and alongside complementary food until 2 years of life. However, there are circumstances where a breastmilk substitute (BMS) may be required. This includes maternal and/or child conditions or personal preference.

The importance of clinical history in the diagnosis of drug hypersensitivity in children.

Background: In case of suspected hypersensitivity reactions (HRs) to drugs, a challenging area for pediatricians is detecting relevant elements in the parent-reported history, in order to reach a definite diagnosis. We analyzed the concordance between the description of the HR and the medical reports documented at the time of the event. Furthermore, we studied any correlation between clinical history variables and the prediction of true allergy.

EAACI/ENDA position paper on drug provocation testing.

In drug hypersensitivity, drug provocation testing (DPT), also called drug challenge, is the gold standard for investigation. In recent years, risk stratification has become an important tool for adjusting the diagnostic strategy to the perceived risk, whilst still maintaining a high level of safety for the patient. Skin tests are recommended before DPT but may be omitted in low-risk patients.
