Management of anaphylaxis in Latin America: current situation

Abstract

Anaphylaxis is a systemic and severe allergic reaction, which can be fatal. The first-line treatment of choice, according to international guidelines, is intramuscular adrenaline. However, different studies show that the performance of health professionals managing anaphylaxis is often inadequate. To assess the current resources available in Latin American countries for the diagnosis and treatment of anaphylaxis. Online survey promoted by the Latin American Society of Allergy and Immunology to representatives of the national allergy societies of Latin American countries. Responses were received from 10 countries out of the 14 countries invited to participate. Only five of the countries have clinical practice guidelines in anaphylaxis. Adrenaline autoinjectors are available only in two countries, Argentina and Brazil, but are not subsidized by public health systems. In all countries, adrenaline is available in ampoules, which is the presentation usually prescribed to patients for self-administration. The use of adrenaline was estimated to be less than 50 % of cases in five countries, while antihistamines and corticosteroids are almost always used. The determination of serum tryptase is possible in some health centers, often private, in five of the countries surveyed. It is necessary to improve resources related to the diagnosis and management of anaphylaxis in Latin American countries.
