Abstract: OBJECTIVES:The aims of the Online Latin American Survey of Anaphylaxis (OLASA) were to identify the main clinical manifestations, triggers, and treatments of severe allergic reactions in patients who were seen by allergists from July 2008 to June 2010 in 15 Latin American countries and Portugal (n = 634).RESULTS:Of all patients, 68.5% were older than 18 years, 41.6% were male, and 65.4% experienced the allergic reaction at home. The etiologic agent was identified in 87.4% of cases and predominantly consisted o… Show more

“…This result was also seen in a previous published study from Switzerland . The range of elicitors may depend on the geographical areas of data assessment as in the United States and Latin America, food and drugs are reported to occur more frequently . However, it has to be considered that in Germany, Austria and Switzerland, patients with insect venom–induced anaphylaxis are preferentially referred to specialized clinics for further diagnostics and treatment.…”

“…Our outcomes could be related to the close geographic proximity of patients to emergency care and the high rates of adrenaline treatment (83%). Our study demonstrated that food anaphylaxis in adults was the most common type, as opposed to drug anaphylaxis seen in reports from Western [18][19][20] and some Asian [21,22] countries. Food was the most common cause of anaphylaxis in prior studies of adults in Singapore [9], China [23], and Saudi Arabia [24], and in the general population in Thailand [25] and Hong Kong [17].…”

“…Estos resultados están en concordancia con los obtenidos en el Registro de Anafilaxia en América Latina publicados en 2011 y 2012. 13,14 Asimismo, se pone de manifiesto que en Amé-rica Latina la determinación de la triptasa sérica, el mejor método in vitro para confirmar una reacción anafiláctica, aún es anecdótica para evaluar una potencial mastocitosis sistémica o el posible riesgo de los pacientes alérgicos al veneno de himenópteros. 15,16 Se reportó que las principales causas de anafilaxia son los alimentos en la edad pediátrica y los medicamentos en la edad adulta.…”
