ABSTRACT

A azatioprina é um dos mais comuns imunomoduladores utilizados no tratamento de Doença de Crohn e Retocolite Ulcerativa Idiopática, sendo que alguns pacientes desenvolvem imunossupressão. Por outro lado, o Strongyloides stercoralis está relacionado à infecção em pacientes imunocomprometidos. No presente estudo, pesquisa-se a prevalência do parasita nos pacientes portadores de Doença Inflamatória Intestinal em uso de azatioprina, através de exames parasitológicos de fezes. Analisa-se também a relação entre eosinofilia e a referida parasitose. No grupo tratado com azatioprina, 5,8% (4/69) dos pacientes estavam infectadospor Strongyloides stercoralis e apresentavam eosinofilia. Naquele tratado com outras drogas, somente 1,8% (1/55) apresentou a infecção e o número de eosinófilos dentro do referencial. Concluiu-se que a infecção pelo parasita é mais freqüente em pacientes da zona rural e que a eosnofilia pode ser um marcador indireto desta infecção.


Although azathioprine is one of the most common immunomodulatory drugs used in the treatment of Crohn's disease and ulcerative colitis, some patients can develop imunnosuppression. Strongyloides stercoralis infection may be associated with immunocompromised patients. In this study, our aim was to evaluate the prevalence of this infection in patients with Inflammatory bowel disease being treated with azathioprine, through parasitologic stool examination. The association between peripheral blood eosinophil counts and the infection was also studied. In the group treated with azathioprine, 5.8% (4/69) patients were infected by Strongyloides stercoralis and showed high level of eosinophil. In the other group, treated with different drug, only one patient (1.8%) revealed the infection and the number of eosinophil was normal. These observations demonstrated that the infection caused by this parasite was more frequent in patients from rural area. Besides, the high level of eosinophil could be an indirect marker for this infection.
