RESUMO

Introdução: O S. de Churg-Strauss (SCS) é uma entidade clínica em que um quadro de asma e eosinofilia coexiste com um atingimento multissistémico.

Caso-clínico: Um homem de 63 anos, com diagnóstico de asma e rinite alérgica desde os 55 anos, inicia um quadro de febre, artrite, polineuropatia e hematúria. Verificou-se a existência de eosinofilia marcada e sinusopatia maxilar e etmoidal bilateral. Iniciou corticoterapia, com regressão completa do quadro clínico e laboratorial. Está actualmente assintomático, com Prednisolona 5mg/dia.

Discussão: Revendo os diagnósticos diferenciais de doença pulmonar com eosinofilia,

verificámos que a presença de atingimento extrapulmonar permite considerarmos o SCS e o S. hipereosinofílico idiopático como únicas hipóteses. A existência de asma selecciona o SCS como o diagnóstico correcto.

Conclusões: a) perante um doente com asma e eosinofilia (superior a 10%), o S. de Churg-Strauss é um diagnóstico a ter sempre presente; b) o diagnóstico é principalmente clínico, de acordo com os critérios de classificação; c) a corticoterapia é muito eficaz e o seu desmame lento permite doses de manutenção baixas.

ABSTRACT

Background: The Churg-Strauss syndrome (CSS) is a disease in which asthma and eosinophilia occur with multisystemic manifestations.

Case-report: A 63 year old male, with a diagnosis of asthma and allergic rhinitis for 8 years, has fever, arthritis, peripheral neuropathy and hematuria. Marked eosinophilia and sinusitis were found. Corticosteroids were given, with complete clinical and laboratorial remission. The patient is asymptomatic with a daily dose of 5mg of Prednisolone.

Discussion: Reviewing the differential diagnosis of pulmonary disease and eosinophilia, the extrapulmonary involvement only exists in the CSS and the hypereosinophilic syndrome. Asthma is present only in the former, and so the Churg-Strauss syndrome was the correct diagnosis.

Conclusions: a) facing a patient with asthma and eosinophilia, the CSS is a diagnosis to have in mind; b) it is a clinical diagnosis, according to classification criteria; c) corticosteroids are very effective and a slow tapering allows low maintenance doses.
