| Summary: | Most of the cases of abdominal angiostrongyliasis in Brazil were reported from the southern States of São Paulo, Paraná, Santa Catarina and Rio Grande do Sul (RS). A study in 27 cases from RS revealed a distinct local epidemiology. Peasants were usually affected, either adults or children, from the mountainous areas in the north of the Suite. There was a seasonal increase in the number of cases, from late spring to autumn, that does not coincide with the rainy season. Besides the most common clinical features of abdominal pain, fever and cosinophilia in the leucogram, painful relapsing episodes were detected in some patients. The abdominal pain could be either localized or diffuse during the rapid evolution to a surgical abdominal condition, with a letality of 7.4%. The use of a serological test and the greater awareness of physicians working in endemic areas is expected to improve the recognition of uncomplicated and benign courses of the disease. This study confirms the known clinical manifestations of abdominal angiostrongyliasis and demonstrates the diversity of its epidemiology. A maioria dos 16 casos de angiostrongilíase abdominal publicados no Brasil até 1989, eram originários dos Estados de São Paulo, Paraná, Santa Catarina e Rio Grande do Sul (RS). Um estudo clínico e epidemiológico em 27 casos no RS revelou aspectos distintos do que é conhecido sobre a ocorrência da doença na Costa Rica: tanto adultos quanto crianças são acometidos, provenientes de áreas serranas do norte do Estado e há uma aparente sazonalidade, não relacionada às chuvas e sim aos meses mais quentes do ano. Alem de confirmar o quadro clínico-laboratorial descrito na literatura (dor abdominal, febre e eosinofilia), o estudo salienta a ocorrência de episódios recorrentes de dor abdominal com remissão espontânea e de outras formas pouco sintomáticas, possivelmente as formas mais comuns de manifestações da doença. Foi observada uma letalidade de 7,4%. Com o alerta aos médicos, especialmente da área endêmica, e o uso de teste sorológico, ... |
