“…The literature reports the spread and urbanization of the VL vector, a process that has transformed several highly populated Brazilian centers into endemic areas for the disease. These centers include Santarém, Pará (PA), Corumbá, MS, Teresina, Piauí (PI), Natal, Rio Grande do Norte (RN), São Luis, Maranhão (MA), Fortaleza, Ceará (CE), Camaçari, Bahia (BA), and Belo Horizonte, Minas Gerais (MG) [11][12][13][14][15][16] .…”

INTRODUCTION: This study sought to describe the profile and geographic distribution of reported cases of visceral leishmaniasis (VL) in the City of Campo Grande, State of Mato Grosso do Sul (MS), Brazil, from 2002 to 2009. METHODS: Human data were collected from the Brazilian National Information System for Notifiable Diseases. Canine cases and entomological data were obtained from the Information Service for Canine Visceral Leishmaniasis Control/Campo Grande, MS. RESULTS: A total of 951 records from 2002 to 2009 were investigated. The number of reported cases of VL in males was significantly higher (p < 0.0001) than that in females. The higher frequency observed among males was associated with age (p < 0.0001), which increased in individuals aged 40 years and older. The overall fatality rate was 7.4%. Entomological surveys conducted in 2006, 2007, and 2009 showed the insect vector Lutzomyia longipalpis to be present in all urban regions of the county. CONCLUSIONS: VL cases in humans and dogs, as well as in vectors, occurs in all urban regions of Campo Grande. Despite not observing tendencies of increase or reduction in the incidence of the disease due to aging, the major incidence in men is higher in those aged 40 years or above.

Visceral leishmaniasis in Brazil: trends and challenges

et al. 2008

The urbanization of visceral leishmaniasis in Brazil has been related to environmental changes, migration, interaction and spread of sylvatic reservoirs and infected dogs to areas with no transmission, and adaptation of the vector Lutzomyia longipalpis to the peridomiciliary environment. From 1980 to 2005, Brazil recorded 59,129 cases of visceral leishmaniasis, 82.5% of which in the Northeast region. Visceral leishmaniasis gradually spread to other regions of the country: in 1998 these other regions reported 15% of all cases, but by 2005 this proportion had increased to 44%. From 1998 to 2005, indigenous cases were reported in 1,904 different municipalities of the country (34.2%). Reservoir and vector control pose major challenges for disease control, since there is a need for better knowledge of vector behavior in urban areas, and control activities involve high operational costs. In recent years the Brazilian Ministry of Health has supported research on the laboratory diagnosis of infection and disease in humans and dogs, treatment of patients, evaluation of the effectiveness of control strategies, and development of new technologies that could contribute to the surveillance and control of visceral leishmaniasis in the country.

“…A duração da doença, desde o início dos sintomas até a hospitalização, variou de 1 a 60 meses, com uma média de 5 meses. Essa duração foi de 1 a 5 meses na experiência de Marzochi 9 . A grande variação constatada nesse indicador revela provavelmente a existência de diferentes níveis de percepção da doença pelos familiares, assim como a ocorrência de formas crônicas, cuja evolução lenta e pouco sintomática apontaria para um estado de equilíbrio estabelecido entre o organismo e o parasita.…”

261 ResumoO autor realizou estudo retrospectivo de 75 crianças portadoras de leishmaniose visceral, internadas para diagnóstico e tratamento nos hospitais públicos de Brasília, no período de primeiro de janeiro de 1982 a primeiro de junho de 1991. Todas as crianças procediam de outros estados do país, sendo que a maioria tinha idade inferior a 6 anos e provinha da zona rural, notadamente da Bahia. Em 78,6% dos casos os sintomas da doença arrastaram-se por período de 1 a 6 meses antes do diagnóstico. Os sinais e sintomas clínicos foram os mesmos já amplamente descritos em trabalhos anteriores, e desnutrição moderada a grave foi encontrada na metade dos pacientes. O quadro laboratorial clássico da patologia foi observado na quase totalidade dos doentes. Todas as crianças foram tratadas com N-metil-glucamina, com resposta terapêutica favorável em 91,4% delas. As complicações mais freqüentemente verificadas foram de natureza infecciosa e hemorrágica. Houve 7 óbitos provocados por pneumonia com insuficiência respiratória e hemorragias digestivas.

AbstractThe author reviewed the records of 75 patients under thirteen years old, with Visceral Leishmaniasis, admitted in the public hospitals of Brasilia, during the period from January 1982 to June 1991. All children were refered to Brasília hospitals from other states of the country, and most of them from the rural areas of Bahia state. In 78.6% of the patients the diagnosis of Visceral Leichmaniasis was confirmed one to six months after the appearance of the first clinical sign of the disease. The clinical manifestations observed in this study were similar to those previously described in the literature. Moderate to severe malnutrition was present in half of the patients. The laboratory tests showed expected results for the disease. All patients were treated with Nmetil-glucamine, and this therapeutic was successful in 91.4% of the children. The complications more frequently seen were infections and hemorrhage. There were 7 deaths due to pneumonia with respiratory failure and digestive bleeding. J. pediatr.

IntroduçãoA Leishmaniose visceral é uma doença potencialmente grave, cuja evolução é muitas vezes fatal, especialmente quando o diagnóstico não é precoce e o tratamento não é adequado.No Brasil, o Calazar apresenta algumas particularidades, entre as quais os fatos de atingir preferencialmente a criança e de contar, para sua expansão, com um segundo reservató-rio natural, representado pela raposa selvagem, pertencente à espécie Lycalopex vetulus 1 .A incidência dessa patologia encontra-se em franca expansão em nosso país 2 , e seu estudo situa-se no quadro mais amplo do controle das grandes endemias, ao lado da malária, da doença de Chagas e da esquistossomose. Por outro lado, a doença, que de início parecia ser apanágio das populações pobres das zonas rurais, começou a ...
