Abstract:
AbstractAlthough a national programme for control of visceral leishmaniosis (VL) is being run in Brazil, the disease continues to spread. This programme is essentially based on culling infected dogs from endemic regions. Thus, there is an urgent need to develop other control measures against VL to deter its advance. Here, a subunit vaccine, a recombinant vaccine, an insecticide-impregnated collar and the associations between these measures were evaluated for reducing the incidence of Leishmania infection in dogs. This was through a cohort study conducted in an endemic region of Brazil, considering the incidence and time of total exposure over a period of 1 year. The incidence of VL was estimated by means of serological and molecular diagnostic tests, 180 and 360 days after the application of the control measures. The estimates of the effectiveness (EF) were not significant in any cohort. The EF of the subunit vaccine, the recombinant vaccine and the collar were 26.4%, 32.8% and 57.7% and the upper limit of the 95% confidence interval for EF were 63.7%, 67.9% and 82.5%, respectively. In conclusion, under the conditions of this study, none of the immunogens for VL control was sufficiently effective to protect dogs against infection. On the other hand, use of collars impregnated with insecticide seems to constitute a method with better prognosis, corroborating other studies in this field.

Abstract:
Zoonotic Visceral Leishmaniasis (ZVL) is one of the world’s deadliest and neglected infectious diseases, according to World Health Organization. This disease is one of major human and veterinary medical significance. The sandfly and the reservoir in urban areas remain among the major challenges for the control activities. In this paper, we evaluated five control strategies (positive dog elimination, insecticide impregnated dog collar, dog vaccination, dog treatment, and sandfly population control), considering disease control results and cost-effectiveness. We elaborated a mathematical model based on a set of differential equations in which three populations were represented (human, dog, and sandfly). Humans and dogs were divided into susceptible, latent, clinically ill, and recovery categories. Sandflies were divided into noninfected, infected, and infective. As the main conclusions, the insecticide impregnated dog collar was the strategy that presented the best combination between disease control and cost-effectiveness. But, depending on the population target, the control results and cost-effectiveness of each strategy may differ. More and detailed studies are needed, specially one which optimizes the control considering more than one strategy in activity.

Abstract:
SUMMARYZoonotic visceral leishmaniasis (ZVL) caused by Leishmania infantum is an important disease of humans and dogs. Here we review aspects of the transmission and control of ZVL. Whilst there is clear evidence that ZVL is maintained by sandfly transmission, transmission may also occur by non-sandfly routes, such as congenital and sexual transmission. Dogs are the only confirmed primary reservoir of infection. Meta-analysis of dog studies confirms that infectiousness is higher in symptomatic infection; infectiousness is also higher in European than South American studies. A high prevalence of infection has been reported from an increasing number of domestic and wild mammals; updated host ranges are provided. The crab-eating fox Cerdocyon thous, opossums Didelphis spp., domestic cat Felis cattus, black rat Rattus rattus and humans can infect sandflies, but confirmation of these hosts as primary or secondary reservoirs requires further xenodiagnosis studies at the population level. Thus the putative sylvatic reservoir(s) of ZVL remains unknown. Review of intervention studies examining the effectiveness of current control methods highlights the lack of randomized controlled trials of both dog culling and residual insecticide spraying. Topical insecticides (deltamethrin-impregnated collars and pour-ons) have been shown to provide a high level of individual protection to treated dogs, but further community-level studies are needed.

Abstract:
We argue that the strategy of culling infected dogs is not the most efficient way to control zoonotic visceral leishmaniasis (ZVL) and that, in the presence of alternative control strategies with better potential results, official programs of compulsory culling adopted by some countries are inefficient and unethical. We base our arguments on a mathematical model for the study of control strategies against ZVL, which allows the comparison of the efficacies of 5, alternative strategies. We demonstrate that the culling program, previously questioned on both theoretical and practical grounds is the less effective control strategy. In addition, we show that vector control and the use of insecticide-impregnated dog collars are, by far, more efficient at reducing the prevalence of ZVL in humans.

Abstract:
The objectives of this article were to discuss the rapid spread of visceral leishmaniasis in urban areas of Brazil and to raise practical questions and perspectives related to control of the disease. Among the proposed methods, the elimination of seropositive dogs is the most controversial and least accepted by society. Its impact on incidence rates varies among studies (positive in some and relatively unimportant in others). Treatment of infected dogs, although widespread in veterinary practice, is based on studies with weak scientific evidence. Insecticide spraying of areas is more acceptable to the population, but is costly and operationally difficult. Intra and inter-urban factors have scarcely been studied and may affect control of the disease. Finally, the article discusses the use of deltamethrin-impregnated dog collars and vaccines, with high expectations for impact on disease transmission, although no product currently available on the market has been fully evaluated, so that further studies are required.

Abstract:
As leishmanioses e particularmente a leishmaniose visceral (LV) são doenças transmitidas por vetores artrópodes candidatas a experimentar uma grande expansão territorial em virtude de problemas relacionados ao aquecimento global. Este evento climático deverá causar grande impacto sobre a distribuição geográfica do artrópode transmissor no Brasil e no mundo. Com efeito, nos últimos 20 anos a situação epidemiológica da LV no Brasil vem se modificando de um padrão esporádico prevalente eminentemente em áreas rurais para uma condição de epidemias peri-urbanas que pode afetar todos os estratos sociais da população, tornando-se uma séria ameaça à saúde pública. As leishmanioses são consideradas até o momento doenças não preveníveis e seu padrão epidemiológico vêm se alterando de forma flagrante, o que demanda urgência para o desenvolvimento de novas ferramentas de controle e tratamento. Dentre as diversas questões levantadas sobre as demandas em pesquisa relacionadas ao controle desta enfermidade, destaca-se a importância de avanços em estudos de epidemiologia quantitativa e modelagem matemática que permitam prever efeitos de vacinações de populações empregando-se imunógenos com eficácia e/ou cobertura vacinal menor que 100%, o que parece ser uma realidade com as vacinas contra leishmanioses desenvolvidas até então pelos laboratórios no mundo todo. O sucesso de estratégias eficazes para o controle da LV depende do conhecimento de diversos parâmetros da dinâmica de infecção nas diferentes populações e espécies que atuam na cadeia epidemiológica da doença. Esse estudo teve objetivo de avaliar a efetividade de vacinas contra leishmaniose em cães bem como da utilização de coleira impregnada com inseticida através de um estudo de coorte realizado em uma região de transmissão moderada de leishmaniose visceral canina. Foram construídas seis coortes compostas por animais não reagentes ao teste rápido TR-DPP&reg; e ao teste EIE-ELISA&reg;. Todos os animais apresentaram estado clínico normal, conforme avaliação semiológica. As coortes compreendem grupos de animais sem qualquer medida de controle (grupo N), grupos de animais com aplicação de coleira (grupo C), grupos de animais vacinados com vacina de subunidade (grupo V1) e grupos de animais vacinados com vacina recombinante (grupo V2) e grupos de animais vacinados e com coleira (grupos V1C e V2C). Foram colhidas amostras de todas as coortes em três tempos com intervalo de seis meses cada, para sorodiagnóstico. A efetividade encontrada ao final de 12 meses de observação para os grupos C, V1, V2, V1C e V2C foram 38,2%, 58,1%, 35%, 68,6% e -36,5% respectivamente com base nos cálculos estatísticos feitos por regressão de Cox para riscos proporcionais. Todas as coortes, mesmo tendo desempenhando alguma efetividade exceto V2C, os resultados dos intervalos de confiança do risco relativo não foram significativos quando comparados ao grupo controle (N).<br>Leishmaniasis and particularly the LV are diseases transmitted by arthropod vectors candidates to experience a wide territorial expansion because of problems related to global warming. This weather event should cause great impact on the geographical distribution of the arthropod transmitter in Brazil and worldwide. Indeed, the past 20 years the epidemiological situation of LV in Brazil has been changing a prevalent sporadic pattern predominantly in rural areas to a condition of peri-urban epidemics that can affect all social strata of the population, making it a serious threat public health. Leishmaniasis are considered so far not preventable disease and its epidemiological pattern have been changing blatantly, which requires urgency to the development of new tools for control and treatment. Among the many questions raised about the demands on research related to the control of this disease, it highlights the importance of advances in quantitative epidemiological studies and mathematical modeling to anticipate vaccinations effects of employing immunogens effectively and / or lower vaccination coverage to 100%, which appears to be a reality with vaccines against leishmaniasis developed so far by laboratories worldwide. The success of effective strategies to control the LV depends on the knowledge of many aspects of the dynamics of infection in different populations and species that act in the epidemiological chain of the disease. This study aims to evaluate the effectiveness of vaccines against leishmaniasis in dogs as well as the use of insecticide impregnated collar with through a cohort study in a high transmission of canine visceral leishmaniasis region. It was built six cohorts composed of non-reactive animals to the rapid test DPP&reg; and EIE-ELISA&reg; test. All the animals had normal clinical status, as symptomatic evaluation. The cohorts include groups of animals without any measure of control (group N), group of animals with collar application (group C), groups of vaccinated animals with subunit vaccine (group V1), group of animals vaccinated with recombinant vaccine (group V2) and groups of animals vaccinated and collar application (V1C and V2C). Samples were collected from all cohorts in three times at intervals of six months each for serodiagnosis. The effectiveness found after 12 months of observation for groups C, V1, V2, V1C and V2C were 38.2%, 58.1%, 35%, 68.6% and -36.5% respectively based on the statistical calculations done by Cox proportional hazards regression to. All cohorts, even though playing some effectiveness except V2C, the results of risk relative confidence intervals were not significant when compared to the control group (N).
