Visceral leishmaniasis in Brazil: revisiting paradigms of epidemiology and control
Dantas-Torres, Filipe;Brando-Filho, Sinval Pinto;
Revista do Instituto de Medicina Tropical de S?o Paulo , 2006, DOI: 10.1590/S0036-46652006000300007
Abstract: in the last 20 years, despite the known underestimation of cases, brazil registered a marked increase in the incidence of visceral leishmaniasis. the main goal of this review is to reflect on some aspects of this zoonosis in brazil and also to encourage the discussion in order to find more viable, effective and affordable strategies to be implemented by the brazilian leishmaniasis control program. the current situation of visceral leishmaniasis in brazil might be seen as a paradox: the most important aspects of the disease are known, but so far the control of this disease has not yet been achieved. the current control strategies have not been able to prevent the geographical expansion, and even a rise in the incidence and lethality of visceral leishmaniasis. there is a need not only for a better definition of priority areas, but also for the implementation of a fieldwork monitoring system to the disease surveillance that could permit a further evaluation of the control program in areas where visceral leishmaniasis is endemic.

Abstract: the objective of this paper is to describe four cases of human parasitism by rhipicephalus sanguineus (latrielle) in brazil. during an investigation regarding the species of ectoparasites of domestic dogs from the metropolitan region of recife, pernambuco state, four dog owners were found to be parasitized by ticks. the ticks were collected from these individuals and their dogs. all the ticks were identified as rhipicephalus sanguineus . these are, to our knowledge, the first four cases of human parasitism by this tick species in brazil. the possible implications of this finding are discussed here.

Abstract: Canine cutaneous leishmaniasis by Leishmania braziliensis is a neglected, but widespread disease of dogs in South America. This paper describes clinical and hematological alterations in 17 L. braziliensis-infected dogs from Brazil. The most common hematological findings were thrombocytopenia (82.4%), anemia (70.6%), low packed cell volume (52.9%) and eosinophilia (41.2%). Twelve (70.6%) dogs displayed at least one evident physical alteration; 11 dogs (64.7%) presented skin lesions, four (23.5%) had weight loss and two (11.8%) onychogryphosis. L. braziliensis-infected dogs present clinical and hematological signs often observed in dogs infected by other pathogens. This indicates that veterinarians and public health workers should not consider the presence of non-specific clinical signs as diagnostic criteria for visceral leishmaniasis in dogs living endemic areas to avoid misdiagnosis and subsequent elimination of dogs infected by L. braziliensis. A leishmaniose cutanea canina causada por Leishmania braziliensis é uma doen a negligenciada, mas disseminada entre c es na America do Sul. Este artigo descreve altera es clínicas e hematológicas em 17 c es infectados por L. braziliensis do Brasil. As altera es hematológicas mais comuns foram trombocitopenia (82,4%), anemia (70,6%), baixo valor de hematócrito (52,9%) e eosinofilia (41,2%). Doze (70,6%) c es apresentaram pelo menos uma altera o física; 11 (64,7%) apresentaram les es cutaneas, quatro (23,5%) perda de peso e dois (11,8%) onicogrifose. C es infectados por L. braziliensis apresentaram altera es clínicas e hematológicas inespecíficas que s o comumente observadas em c es infectados por outros patógenos. Isso indica que veterinários e profissionais de saúde pública n o deveriam considerar a presen a de tais sinais clínicos como critério de diagnóstico para leishmaniose visceral em c es, em áreas endêmicas, no intuito de evitar um diagnóstico equivocado e a subsequente elimina o de c es infectados por L. braziliensis.

Abstract: introduction: phlebotomine sand flies are small insects of great medical relevance. this article presents an updated list of the phlebotomine sand flies occurring in the state of pernambuco, brazil. methods: a review of literature published since the 1940s up to may 2010 was conducted and voucher material deposited in reference collections were studied. results: a total of 37 phlebotomine species have previously been reported as occurring in pernambuco, but the record of six species needs confirmation. conclusions: this work provides an updated list of phlebotomine sand flies of pernambuco, with some notes on their taxonomy, ecology, distribution and epidemiological relevance.

Abstract: a new outbreak of american tegumentary leishmaniasis among military personnel is reported, with 71 cases confirmed by means of clinical, epidemiological and laboratory criteria. seven samples were isolated and were identified as leishmania (viannia) braziliensis. the occurrence of outbreaks in this region confirms the endemic nature of this disease, and the magnitude of the occurrence seems to be related to non-adoption of individual protection measures.

Abstract: american tegumentary leishmaniasis (atl) is present in all regions of pernambuco state, brazil, where it is spreading, with the emergence of foci in new areas like the municipality (county) of moreno in greater metropolitan recife. the objective of the current study was to assess the prevalence of infection and identify autochthonous cases of atl. in april 2006 a population survey was performed using a questionnaire and the montenegro skin test (mst) in 481 individuals from the pinto sugar mill, of whom 47% were males and 74% were younger than 30 years. one hundred forty-four individuals (30%) showed a positive mst. of these, five presented active lesions, 41 were cured after meglumine antimoniate treatment, and one showed a spontaneous cure. indirect immunofluorescence (iif) was performed on sera from 89 individuals and showed a 36% positive rate. the high atl prevalence demonstrates the epidemiological spread of the disease in greater metropolitan recife, a worrisome development since there are no effective measures for atl control except ecological awareness raising to minimize the risk of infection.

Abstract: the aim of this study was to identify the fauna of phlebotomine sandflies in an area with incidence of american visceral leishmaniasis (avl) in s?o vicente férrer, a municipality (county) located in the northern zona da mata in pernambuco state, brazil. sandfly captures were conducted monthly for four nights/month from december 2002 to november 2003, by means of manual captures (with a shannon trap) and by cdc light traps. a total of 23,156 specimens of phlebotomines sandflies were collected in a remnant of the atlantic rainforest, houses, and animal shelters. lutzomyia complexa was the most prevalent species, with a frequency of 62.5% (14,445/23,156), followed by lutzomyia migonei, with 33.2% (7,677/23,156). no lutzomyia longipalpis (the main vector of leishmania chagasi in brazil and the americas) was found in the target area. some specimens were dissected, but no leishmania parasites were found.

Revista da Sociedade Brasileira de Medicina Tropical , 2006, DOI: 10.1590/S0037-86822006000400007
Abstract: this study aimed to demonstrate the geographical expansion of visceral leishmaniasis in pernambuco state, brazil. with data on the number of visceral leishmaniasis cases notified from 1990 to 2001, maps showing the biannual evolution of the geographical distribution of the disease per municipality were elaborated. a map of the cumulative geographical distribution of the cases registered during the whole period was also constructed. from 1990 to 2001, 1,737 cases of visceral leishmaniasis were notified in pernambuco. in 1990, 15.2% (n = 28) of the municipalities notified cases of the disease. in contrast, this percentage increased to 78.3% (n = 144), over an eleven-year period. the map of cumulative geographical distribution during the whole period shows a notable concentration of cases in agreste and sert?o. a notable geographical expansion of visceral leishmaniasis in pernambuco also occurred, probably reflecting the low impact of the current control measures and, possibly, an improvement in the notification system.
