Apresenta-se o resultado de um estudo de campo sobre a leishmaniose visceral autóctone da Ilha de São Luís. Com início em 2004 e término em 2006, a pesquisa visou conhecer aspectos epidemiológicos e clínicos determinantes da endemia. Foram analisados 299 casos autóctones, sendo 83,6% em menores de 9 anos e 54,1% do sexo masculino. O agravo ocorreu em todos os meses do ano com pico em junho. O coeficiente de incidência foi reduzido de 46,1 para 35,2 casos por 100.000 habitantes nos anos estudados. O diagnóstico teve confirmação laboratorial em 93,3% dos casos. O tratamento de escolha foi à base de N-metilglucamina com percentual de cura de 96,1%. A letalidade média foi de 3,7%. Em função da inexistência de ações mais sistemáticas de controle, propõe-se a criação de um programa a ser desenvolvido pelos municípios sob a coordenação da Secretaria de Estado da Saúde.
A prospective study was performed to identify knowledge concerning visceral leishmaniasis (VL) in endemic areas of Maranhao, amongst the rural population of the Codo township and in a peripheral urban area (an old settlement, Maracana, on the outskirts of the city of Sao Luis, and Vila Nova/Bom Viver, Paco do Lumiar township). A total of 283 persons were interviewed, including 53 from Maracana, 103 from Vila Nova/Bom Viver, and 127 from Codo. The sites presented favorable conditions for the development and maintenance of VL. Some 93.8% of those interviewed had heard of kala-azar. In Maracana, 50.9% referred to sandflies as responsible for the transmission of VL, while 87.2% knew that dogs are the main link in the epidemiological cycle of the disease. Some 77.8% of those interviewed did not know how to control the disease. As regards manifestations of the disease, they largely associated it with fever, anemia, weight loss, and an enlarged abdomen. Only five individuals knew that Glucantimeis used to treat VL. We conclude that knowledge is poor with regard to all aspects of VL in both the rural and peripheral urban area.
Visceral leishmaniasis (kala-azar) was definitively an important disease of the state of Maranhão, Brasil since 1982. Since of then, many authors have been working with this topic in spite of reports. Nevertheless, the aspects of diagnosis, treatment an control of cure went through still hard worried the authors have been studying the disease, that came at São Luís Island since of the destabilization of the ecotopes of Lutzomya longipalpis, most important sandflies bites. After 1993 the constatation of cases with bad response to pentavalent antimonial (Glucantime) comes to add the other worries. This actual trial accost the disease and conclude about an existence of failures to Glucantime being important to have much vigilance in the diagnosis, treatment and control of cure of the patients.
