Latin American anaphylaxis registry.

Background: Recent data about clinical features, triggers and management of anaphylaxis in Latin America is lacking. Objective: To provide updated and extended data on anaphylaxis in this region. Method: An online questionnaire was used, with 67 allergy units involved from 12 Latin-American countries and Spain. Among data recorded, demographic information, clinical features, severity, triggering agents, and treatment were received. Results: Eight hundred and seventeen anaphylactic reactions were recorded. No difference in severity, regardless of pre-existing allergy or asthma history was found. Drug induced anaphylaxis (DIA) was most frequent (40.6%), followed by food induced anaphylaxis (FIA) (32.9%) and venom induced anaphylaxis (VIA) (12%). FIA and VIA were more common in children-adolescents. Non-steroidal anti-inflammatory drugs (NSAIDs) and beta-lactam antibiotics (BLA) were the most frequent drugs involved. Milk (61.1% of FIA) and egg (15.4% of FIA) in children, and shellfish (25.5% of FIA), fresh fruits (14.2% of FIA), and fish (11.3% of FIA) in adults were the most common FIA triggers. Fire ants were the most frequent insect triggers, and they induced more severe reactions than triggers of FIA and DIA (p < 0.0001). Epinephrine was used in 43.8% of anaphylaxis episodes. After Emergency Department treatment, epinephrine was prescribed to 13% of patients. Conclusions: Drugs (NSAIDs and BLA), foods (milk and egg in children and shellfish, fruits and fish in adults) and fire ants were the most common inducers of anaphylaxis. Epinephrine was used in less than half of the episodes emphasizing the urgent need to improve dissemination and implementation of anaphylaxis guidelines.

Diretriz Latino-americana sobre o Diagnóstico e Tratamento da Alergia Ocular ­ Em nome da Sociedade Latinoamericana de Alergia, Asma e Imunologia (SLAAI) / Latin American Guideline on the Diagnosis and Treatment of Ocular Allergy ­ On behalf of the Latin American Society of Allergy, Asthma and Immunology (SLAAI)

A alergia ocular, também conhecida como conjuntivite alérgica (CA), é uma reação de hipersensibilidade mediada por imunoglobulina E (IgE) do olho desencadeada por aeroalérgenos, principalmente ácaros da poeira doméstica e pólen de gramíneas. Os sintomas geralmente consistem em prurido ocular ou periocular, lacrimejamento e olhos vermelhos que podem estar presentes durante todo o ano ou sazonalmente. A alergia ocular tem frequência elevada, é subdiagnosticada e pode ser debilitante para o paciente. É potencialmente danosa para a visão, nos casos em que ocasiona cicatrização corneana grave, e na maioria dos pacientes associa-se a outros quadros alérgicos, principalmente rinite, asma e dermatite atópica. É classificada em conjuntivite alérgica perene, conjuntivite alérgica sazonal, ceratoconjuntivite atópica e ceratoconjuntivite vernal. O diagnóstico procura evidenciar o agente etiológico e a confirmação se dá pela realização do teste de provocação conjuntival. O tratamento baseia-se em evitar o contato com os desencadeantes, lubrificação, anti-histamínicos tópicos, estabilizadores de mastócitos, imunossupressores e imunoterapia específica com o objetivo de obter o controle e prevenir as complicações da doença.

Ocular allergy, also known as allergic conjunctivitis, is an immunoglobulin E-mediated hypersensitivity reaction of the eye triggered by airborne allergens, primarily house dust mites and grass pollen. Symptoms usually consist of ocular or periocular itching, watery eyes, and red eyes that may be present year-round or seasonally. Ocular allergy has a high frequency, is underdiagnosed, and can be debilitating for the patient. It is potentially harmful to vision in cases of severe corneal scarring, and in most patients, it is associated with other allergic conditions, especially rhinitis, asthma, and atopic dermatitis. It is classified as perennial allergic conjunctivitis, seasonal allergic conjunctivitis, atopic keratoconjunctivitis, and vernal keratoconjunctivitis. Diagnosis seeks to identify the etiologic agent, and confirmation is given by conjunctival provocation testing. Treatment is based on avoiding contact with triggers, lubrication, topical antihistamines, mast cell stabilizers, immunosuppressants, and specific immunotherapy with the aim of achieving control and preventing disease complications.

Contaminación atmosférica en América Latina: impacto en la salud Y regulación actual - reporte del grupo del Comité de Aerobiología de la Sociedad Latinoamericana de Asma, Alergia e Inmunología / Atmospheric pollution in Latin America: impact on health and current regulation - report of the Aerobiology Committee of the Latin American Society of Asthma, Allergy and Immunology

La contaminación ambiental, en todas sus vertientes, tiene un efecto de enormes dimensiones no sólo sobre la existencia del planeta, sino también sobre la salud de la humanidad. América Latina es una región privilegiada ambientalmente, debido a su gran acervo de patrimonio natural, biodiversidad y posibilidades de provisión de servicios ambientales. Pero, a su vez, es una de las regiones más urbanizadas del orbe, con las afectaciones y presión al medio ambiente que esto implica, principalmente en la calidad del aire que se respira, derivadas de antiguos patrones productivos y de ocupación territorial, que se han agudizado como consecuencia del modelo de desarrollo predominante. Los efectos sobre la salud humana de diversas sustancias contaminantes están relacionados a procesos inflamatorios sobre mucosas y al aumento de la morbimortalidad en personas con enfermedades preexistentes, principalmente de los sistemas neurológico, cardiaco y respiratorio, en particular las enfermedades alérgicas respiratorias. La región latinoamericana enfrenta importantes problemas ambientales, determinados por los patrones de uso de sus recursos naturales, los sistemas de producción, los hábitos de consumo de las poblaciones humanas y la regulación gubernamental ambiental, que en muchos casos es laxa o pobremente implementada por los gobiernos en turno.

Air quality, in all its dimensions, has a major effect not only on the existence of the planet, but also on human health. Latin America is an environmentally privileged region, due to its great wealth of natural heritage, biodiversity and possibilities of provision of environmental services. But, at the same time, it is one of the most urbanized regions in the world, with the effects and pressure on the environment that this implies, mainly in the air quality, due to patterns of production and of territorial occupation, which they have exacerbated as a result of the predominant development model. The effects of diverse pollutant substances on the human health are related to inflammatory processes on mucous membranes and to increased morbidity and mortality in people with pre-existing diseases, especially of the neurological, cardiac and respiratory systems, in particular respiratory allergic illnesses. The Latin American region faces important environmental problems determined by the patterns of use of its natural resources, systems of production, habits of consumption of the human populations, and environmental governmental regulation, which is often lax or poorly implemented by the local authorities.
