RESUMEN
BACKGROUND: Patients with a history of anaphylaxis are at risk of future anaphylactic reactions. Thus, secondary prevention measures are recommended for these patients to prevent or attenuate the next reaction. METHODS: Data from the Anaphylaxis Registry were analyzed to identify secondary prevention measures offered to patients who experienced anaphylaxis. Our analysis included 7788 cases from 10 European countries and Brazil. RESULTS: The secondary prevention measures offered varied across the elicitors. A remarkable discrepancy was observed between prevention measures offered in specialized allergy centers (84% of patients were prescribed adrenaline autoinjectors following EAACI guidelines) and outside the centers: Here, EAACI guideline adherence was only 37%. In the multivariate analysis, the elicitor of the reaction, age of the patient, mastocytosis as comorbidity, severity of the reaction, and reimbursement/availability of the autoinjector influence physician's decision to prescribe one. CONCLUSIONS: Based on the low implementation of guidelines concerning secondary prevention measures outside of specialized allergy centers, our findings highlight the importance of these specialized centers and the requirement of better education for primary healthcare and emergency physicians.

Anaphylaxis is a severe allergic reaction with a rapid onset and it is potentially life-threatening. Its clinical manifestations are varied; they may affect the skin, the cardiovascular system, the respiratory system, and the digestive system, among others. The treatment of choice, which is an intra-muscular injection of epinephrine (adrenaline), must be applied promptly. Therefore, being prepared to recognize it properly is of crucial importance. The objective of this clinical practice guide is to improve the knowledge of health professionals about anaphylaxis and, consequently, to optimize the treatment and long-term management of this reaction. This guide is adapted to the peculiarities of Latin America; especially in matters regarding the treatment. The need to introduce epinephrine auto-injectors in countries that don't have them yet is highlighted.
La anafilaxia es una reacción alérgica grave de instauración rápida y potencialmente mortal. Sus manifestaciones clínicas son muy variadas, pudiendo afectar la piel, el sistema cardiovascular, el aparato respiratorio y el digestivo, entre otros. El tratamiento de elección, mediante la inyección intramuscular de adrenalina, debe ser precoz. Por lo anterior, es vital estar preparados para reconocerla adecuadamente. El objetivo de la presente guía de actuación clínica es mejorar el conocimiento de los profesionales sanitarios sobre anafilaxia y, consecuentemente, optimizar el tratamiento y manejo a largo plazo de esta entidad. La guía está adaptada a las peculiaridades de América Latina, especialmente en los aspectos relativos al tratamiento. Se destaca la necesidad de introducir los autoinyectores de adrenalina en los países que no dispongan de ellos.
