Red blood cell distribution width and haemoglobin are associated with hospital admission in patients with acute allergic reactions.

Introduction: Red blood cell distribution width (RDW) is significantly associated with a variety of human disorders. This study aimed to investigate whether RDW value at admission may predict the need of hospitalisation in patients presenting to the emergency department (ED) with acute allergic reactions.

Materials And Methods: The study population consisted of adult patients (aged > 17) admitted to the ED for acute allergic reactions.

Spring season birth is associated with higher emergency department admission for acute allergic reactions.

Background: Acute allergic reactions are important causes of emergency department (ED) admission, imposing a significant clinical and organizational burden. Since the season of birth is linked with early exposure to allergens, this study was aimed to establish whether an association exists between season of birth and incidence and severity of acute allergic reactions in the ED.

Methods: The electronic hospital database was searched to identify all consecutive adult patients who were admitted to the ED for acute allergic reactions (acute urticaria, acute angioedema, urticaria-angioedema and anaphylaxis) during a 1-year period.
