Allergy training and immunotherapy in Latin America: results of a regional overview.

BACKGROUND: One main practice gap in allergology that has been detected in several regions of the world is the application of specific immunotherapy (SIT). The prescription and practice of SIT should characterize allergologic specialists, but there are regional discrepancies in such practice. A detailed knowledge of the regulatory and legislation aspects and drawbacks would help improve and harmonize SIT practice. OBJECTIVE: To describe in Latin America the level of allergy training and the characteristics of the use of SIT, including the medical and legal aspects. METHODS: Three sources were used: a 24-item questionnaire sent to 22 allergologic leaders in 11 Latin American countries, 2 face-to-face meetings, and information from health authorities involved in the approval of medical substances. RESULTS: In 56% of countries, the specialty of allergology is a third-level care specialty and/or a subspecialty. Two countries have a special training program for pediatric allergists. Passing a board examination is mandatory in 3 countries, and recertification every 2 to 5 years occurs without examination. Sublingual and subcutaneous SITs are available in all Latin American countries. No legislation restricts SIT prescription and it can be performed by nonspecialists in 7 of 11 countries. In 90% of countries, allergists use allergen extracts from the United States (subcutaneous immunotherapy) and Europe (sublingual and subcutaneous immunotherapies), and 50% also manufacture extracts locally. Only 1 country has legal requirements for the quality of raw materials. CONCLUSION: The present analysis helps to identify gaps in the field of allergologic training and SIT in Latin America, many of them amendable.

Digital tools in allergy and respiratory care.

Patient care in the allergy and respiratory fields is advancing rapidly, offering the possibility of the inclusion of a variety of digital tools that aim to improve outcomes of care. Impaired access to several health care facilities during the COVID-19 pandemic has considerably increased the appetite and need for the inclusion of e-health tools amongst end-users. Consequently, a multitude of different e-health tools have been launched worldwide with various registration and access options, and with a wide range of offered benefits. From the perspective of both patients and healthcare providers (HCPs), as well as from a legal and device-related perspective, several features are important for the acceptance, effectiveness,and long-term use of e-health tools. Patients and physicians have different needs and expectations of how digital tools might be of help in the care pathway. There is a need for standardization by defining quality assurance criteria. Therefore, the Upper Airway Diseases Committee of the World Allergy Organization (WAO) has taken the initiative to define and propose criteria for quality, appeal, and applicability of e-health tools in the allergy and respiratory care fields from a patient, clinician, and academic perspective with the ultimate aim to improve patient health and outcomes of care.

Anaphylaxis and alternative medicine: an unexpected association.

PURPOSE OF REVIEW: The present review aims to evaluate the use of complementary medicine among patients with allergic disorders, highlighting the risk of adverse reactions, which are often not considered and referred by patients to specialists. RECENT FINDINGS: Complementary medicine is often used in clinical practice and preferred by patients as it is considered a natural therapy compared to traditional medicine. This choice is because of various cultural and socioeconomics aspects. SUMMARY: The use of complementary medicine and its adverse reactions, often as severe as anaphylaxis, is frequently reported in atopic patients, in which a cross reactivity between the natural herbs used and the pollen to which they are sensitized is possible.Therefore, a personalized approach in atopic patients before the use of natural products is crucial to prevent any adverse reactions.

Current and Potential Biologic Drugs for the Treatment of Chronic Urticaria.

This article reviews biologic treatments that are currently applied for the treatment of severe chronic urticaria. Monoclonal anti-immunoglobulin E (omalizumab) is effective and safe in many patients, but accessibility and cost constitute barriers to its wider use. Questions on the optimal duration of the treatment and possible symptom recurrences after discontinuing the drug are still raised. A discussion is presented about several other biologics currently under investigation with potential to be incorporated in the near future in patients with severe chronic urticaria.

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.
