ABSTRACT

Hereditary angioedema is an autosomal dominant disease characterized by recurrent angioedema attacks with the involvement of multiple organs. The disease is unknown to many health professionals and is therefore underdiagnosed. Patients who are not adequately diagnosed and treated have an estimated mortality rate ranging from 25% to 40% due to asphyxiation by laryngeal angioedema. Intestinal angioedema is another important and incapacitating presentation that may be the main or only manifestation during an attack. In this article, a group of experts from the "Associação Brasileira de Alergia e Imunologia (ASBAI)" and the "Grupo de Estudos Brasileiro em Angioedema Hereditário (GEBRAEH)" has updated the Brazilian guidelines for the diagnosis and treatment of hereditary angioedema.

ABSTRACT

O angioedema hereditário é uma doença autossômica dominante caracterizada por crises de edema com o envolvimento de múltiplos órgãos. A doença é desconhecida por muitos profissionais da área da saúde e, portanto, subdiagnosticada. Os pacientes que não são diagnosticados e tratados adequadamente têm uma mortalidade estimada de 25% a 40%, devido ao angioedema da laringe, resultando em asfixia. O angioedema de alças intestinais é outra manifestação importante e incapacitante, que pode ser a principal ou a única durante uma crise da doença. Neste cenário, um grupo de especialistas da Associação Brasileira de Alergia e Imunologia (ASBAI) e do Grupo de Estudos Brasileiro em Angioedema Hereditário (GEBRAEH) atualizou as diretrizes para o diagnóstico e terapia do angioedema hereditário.

Patients who are not adequately diagnosed and treated have an estimated mortality rate ranging from 25% to 40%, due to laryngeal angioedema, which results in asphyxia. Angioedema affecting bowel loops is another important, incapacitating presentation that may be the main or only manifestation during a crisis. In this scenario, a group of experts affiliated with Associação Brasileira de Alergia e Imunologia (ASBAI) and Grupo de Estudos Brasileiro em Angioedema Hereditário (GEBRAEH) has updated the guidelines for the diagnosis and treatment of hereditary angioedema.

ABSTRACT

Resumo A piomiosite é uma infecção piogênica da musculatura esquelética, decorrente da disseminação hematogênica e geralmente acompanhada de formação de abscesso localizado. Esta infecção da musculatura é raramente descrita em adultos com lúpus eritematoso sistêmico (LES) e, até onde se sabe, ainda não o foi em pacientes com LES juvenil (LESJ). De nossos 289 pacientes com LESJ, uma apresentou piomiosite. Diagnosticada com LESJ aos 10 anos de idade e após seis anos de tratamento com prednisona, azatioprina e hidroxicloroquina, a paciente foi hospitalizada em razão de um histórico de 30 dias de dor insidiosa na coxa esquerda, sem relato algum de trauma aparente ou febre. O exame físico mostrou músculos sensíveis e com endurecimento lenhoso. Os exames laboratoriais revelaram anemia, aumento de reagentes de fase aguda e enzimas musculares normais. A tomografia computadorizada da coxa esquerda mostrou coleção no terço médio do vasto intermédio, sugerindo estágio purulento de piomiosite. Iniciou-se tratamento com antibiótico de largo espectro, que levou à resolução clínica completa. Em suma, descreveu-se o primeiro caso de piomiosite em pacientes com LESJ encontrado neste serviço. Este relato reforça que a presença de dor muscular localizada em pacientes imunocomprometidos, ainda que sem aumento de enzimas musculares, deve sugerir o diagnóstico de piomiosite. Recomenda-se tratamento imediato com antibióticos.


Abstract Pyomyositis is a pyogenic infection of skeletal muscle that arises from hematogenous spread and usually presents with localized abscess. This muscle infection has been rarely reported in adult-onset systemic lupus erythematous and, to the best of our knowledge, has not been diagnosed in pediatric lupus population. Among our childhood-onset systemic lupus erythematous population, including 289 patients, one presented pyomyositis. This patient was diagnosed with childhood-onset systemic lupus erythematous at the age of 10 years-old. After six years, while being treated with prednisone, azathioprine and hydroxychloroquine, she was hospitalized due to a 30-day history of insidious pain in the left thigh and no apparent trauma or fever were reported. Her physical examination showed muscle tenderness and woody induration. Laboratory tests revealed anemia, increased acute phase reactants and normal muscle enzymes. Computer tomography of the left thigh showed collection on the middle third of the vastus intermedius, suggesting purulent stage of pyomyositis. Treatment with broad-spectrum antibiotic was initiated, leading to a complete clinical resolution. In conclusion, we described the first case of pyomyositis during childhood in pediatric lupus population. This report reinforces that the presence of localized muscle pain in immunocompromised patients, even without elevation of muscle enzymes, should raise the suspicion of pyomyositis. A prompt antibiotic therapy is strongly recommended.
