ABSTRACT

Abstract This second joint document, written by experts from the Brazilian Association of Allergy and Immunology (ASBAI) and Brazilian Society of Anesthesiology (SBA) concerned with perioperative anaphylaxis, aims to review the pathophysiological reaction mechanisms, triggering agents (in adults and children), and the approach for diagnosis during and after an episode of anaphylaxis. As anaphylaxis assessment is extensive, the identification of medications, antiseptics and other substances used at each setting, the comprehensive data documentation, and the use of standardized nomenclature are key points for obtaining more consistent epidemiological information on perioperative anaphylaxis.


Resumo Este segundo documento, escrito por especialistas da Associação Brasileira de Alergia e Imunologia (ASBAI) e da Sociedade Brasileira de Anestesiologia (SBA) interessados no tema anafilaxia perioperatória, tem por objetivo revisar os mecanismos fisiopatológicos, agentes desencadeantes (em adultos e crianças), assim como a abordagem diagnóstica durante e após o episódio. Por se tratar de uma avaliação abrangente, a identificação das medicações, antissépticos e outras substâncias usadas em cada região, registros detalhados, e nomenclatura padronizada são pontos fundamentais para a obtenção de dados epidemiológicos mais fidedignos sobre a anafilaxia perioperatória.

ABSTRACT

Abstract Experts from the Brazilian Association of Allergy and Immunology (ASBAI) and the Brazilian Society of Anesthesiology (SBA) interested in the issue of perioperative anaphylaxis, and aiming to strengthen the collaboration between the two societies, combined efforts to study the topic and to prepare a joint document to guide specialists in both areas. The purpose of the present series of two articles was to report the most recent evidence based on the collaborative assessment between both societies. This first article will consider the updated definitions, treatment and guidelines after a perioperative crisis. The following article will discuss the major etiologic agents, how to proceed with the investigation, and the appropriate tests.


Resumo Especialistas da Associação Brasileira de Alergia e Imunologia (ASBAI) e da Sociedade Brasileira de Anestesiologia (SBA) interessados no tema anafilaxia perioperatória reuniram-se com o objetivo de intensificar a colaboração entre as duas sociedades no estudo desse tema e elaborar um documento conjunto que possa guiar os especialistas de ambas as áreas. O objetivo desta série de dois artigos foi mostrar as evidências mais recentes alicerçadas na visão colaborativa entre as sociedades. Este primeiro artigo versará sobre as definições mais atuais, formas de tratamento e as orientações após a crise no perioperatório. No próximo artigo serão discutidos os principais agentes causais e a condução da investigação com testes apropriados.

ABSTRACT

OBJETIVO: De acordo com alguns estudos, a associação de leflunomida (LEF) a pacientes portadores de artrite reumatoide não responsivos a metotrexato (MTX) aumentou a eficácia do tratamento, elevando, porém, o risco de toxicidade hepática. Este estudo objetiva avaliar a incidência de toxicidade hepática no tratamento da artrite reumatoide ativa usando terapia combinada de LEF e MTX em comparação com monoterapia com MTX. MÉTODOS: Entre fevereiro e setembro de 2009, foram arrolados 97 pacientes consecutivos acompanhados pelo Hospital Universitário da Universidade Federal de Santa Catarina, Brasil. Pacientes com artrite reumatoide em uso de MTX somente ou em combinação com LEF tiveram seus prontuários sistematicamente revisados. As enzimas alanino/aspartato aminotransferases foram analisadas retrospectivamente desde o tratamento com MTX ou MTX mais LEF. Hepatotoxicidade foi definida como um aumento das enzimas hepáticas acima de duas vezes o limite superior da normalidade. RESULTADOS: 71 pacientes foram incluídos no estudo: 36,6 por cento usavam 20-25 mg/semana de MTX e 63,4 por cento usavam 20-25 mg/semana de MTX associado a 20 mg/ dia de LEF. Dos pacientes em terapia combinada, 11,1 por cento tinham níveis anormais das enzimas hepáticas versus 11,5 por cento daqueles em monoterapia (P = 1,0). Níveis anormais de aminotransferases têm sido observados em pacientes com artrite reumatoide tanto em monoterapia com MTX quanto com LEF. Em nosso estudo, não encontramos diferença entre as percentagens de elevação das aminotransferases em pacientes tratados somente com MTX ou com terapia combinada. CONCLUSÃO: A combinação de MTX e LEF em pacientes com artrite reumatoide é geralmente segura e bem tolerada.


OBJECTIVE: Some studies have reported that adding leflunomide (LEF) to the treatment of rheumatoid arthritis (RA) in patients who do not respond to methotrexate (MTX) improved efficacy but increased the risk of liver toxicity. This study aimed at assessing the incidence of liver toxicity in patients with active RA using the LEF and MTX combination therapy in comparison with that of patients on MTX monotherapy. METHODS: Between February and September 2009, 97 consecutive patients followed up at the University Hospital of the Universidade Federal de Santa Catarina, Brazil, were enrolled. RA patients on MTX alone or using the LEF and MTX combination had their medical records systematically reviewed. The alanine/aspartate aminotransferase enzymes were retrospectively analyzed since the beginning of treatment with MTX or MTX plus LEF. Hepatotoxicity was defined as an increase of at least two-fold the upper limits of normal of the liver enzymes. RESULTS: 71 RA patients were included in the study: 36.6 percent were using 20-25 mg/week of MTX alone and 63.4 percent were using 20-25 mg/week of MTX plus 20 mg/day of LEF. Of the patients on the combination therapy, 11.1 percent had abnormal levels of liver enzymes versus 11.5 percent of the patients on monotherapy (P = 1.0). Abnormal aminotransferase levels have been seen with both MTX and LEF monotherapies in patients with RA. In our study, no difference was found between the percentages of aminotransferase elevations of patients being treated with MTX alone or in combination with LEF. CONCLUSION: The combination of MTX and LEF in RA patients is generally safe and well tolerated.
