Abstract
Visceral leishmaniasis (kala-azar) is an important cause of morbidity and mortality in widely scattered areas of the world. To better characterize the South American form of the disease, the clinical and laboratory manifestations of 29 patients admitted to hospital (18 male and 11 female patients, mean age 4.9 years), were assessed in an endemic area in northeastern Brazil. Fever, weight loss, pronounced splenomegaly, hepatomegaly, anemia, thrombocytopenia, relative neutropenia, hypoalbuminemia and hypergammaglobulinemia were found in the majority of patients. Symptoms were often present for two or more months before diagnosis. Secondary infections complicated many cases; there were ten cases of pneumonia and half of the patients had one or more intestinal parasites. The average length of hospital stay was 27 days; all patients were treated with meglumine antimoniate (Glucantime). The mortality rate was 3%. American visceral leishmaniasis remains an important disease among children living in endemic areas.
