In order to see how the treatments affect cytokine production, draining lymph nodes of mice were excised and the isolated cells were cultured and stimulated with PMA/I. IL-10, IL-12 and IFN-γ secretion was measured in the supernatants harvested 24 hr after stimulation. Interestingly, infected mice without any treatment (Group P) produced significantly higher IFN-γ compared to non-infected control mice. This finding is in consonance with the previous reports demonstrating that IFN-γ production in BALB/c is not impaired even when the disease completely developed (Lang et al., 2003; Sommer et al., 1998). In addition, the disease severity would be affected by a mechanism independent of conventional helper T-cell responses since B6.C (lmr1/2) mice had similar cytokine levels to the parental C57BL/6 mice despite increased susceptibility and C.B6 (lmr1, lmr2) were similar to BALB/c despite increased resistance (Elso et al., 2004). In human visceral leishmaniasis it has also been found that plasma ...
Responsible for up to 30,000 deaths annually, leishmaniasis is a complex spectrum of diseases endemic in 97 countries around the globe. Disease control relies heavily on the early diagnosis and treatment of the active cases (relevant for anthroponotic disease), although it is widely accepted that a prophylactic vaccine for human leishmaniasis is the way to achieve the successful elimination of human disease (taking in consideration the vast list of non-human reservoirs that enable the perpetuation of parasites all around the globe). The notion that infection leads to strong and long-lasting immunity against leishmaniasis supports vaccination as an achievable goal. However, and in spite of the different candidates tested along the years, till date, we still do not have an approved vaccine for humans. In this chapter, we will explore the last advances made in the field of vaccines against Leishmania without forgetting the historical perspective, essential to the understanding of the road already undergone

OBJECTIVES. Canine leishmaniasis is an endemic zoonotic disease highly widespread in the Mediterranean basin. There is a broad spectrum on clinical features ranging from local cutaneous forms to visceral forms, depending mainly on hosts immune response. Mucosal leishmaniasis is an atypical presentation form produced by metastatic leishmanial dissemination all through the mucous membranes that was firstly described by Font et al. in 1995. To try to describe five new cases of mucosal leishmaniasis is the first objective of this work, one of the cases was localized on a bitch nipple, and that, to the authors knowledge hasnt been previously described. Second objective is focused in the study of the incidence of this rare leishmaniasis type, in order to make a right valuation within the differential diagnosis of tumor-like lesions of mucous membranes.. MATERIALS. The present study was accomplished over 983 dogs that were brought to Facultad de Veterinaria de Zaragoza during the 2000-2001 years ...

PENAFORTE, Klauber Menezes et al. Leishmania infection in a population of dogs: an epidemiological investigation relating to visceral leishmaniasis control. Rev. Bras. Parasitol. Vet. [online]. 2013, vol.22, n.4, pp.592-596. ISSN 1984-2961. https://doi.org/10.1590/S1984-29612013000400022.. Identification of factors associated with Leishmania infection in dogs is essential for targeting visceral leishmaniasis control actions. Thus, the present study analyzed some of these factors in a population of dogs in a Brazilian municipality, along with the limitations of control strategies implemented there. The association between the exposure variables and occurrences of infection was analyzed through logistic regression models. The disease control interventions were treated qualitatively. Out of the 755 animals examined, 13.6% (103/755) were seropositive. Of these, 23.3% (24/103) were asymptomatic and 76.7% (79/103) presented at least one clinical sign possibly associated with visceral leishmaniasis. ...
KEYWORDS: Leishmania; Swiss mice; Microbiota ; Germfree; Th1; Leishmaniasis. INTRODUCTION Leishmaniasis is a disease caused by parasites of the genus Leishmania that produce diversified clinical manifestation depending upon the characteristics of the parasite and on the immune response of the host2,5. The present understanding of the factors that lead to this diversity of clinical symptoms was obtained, in large part, through studies using isogenic mice experimentally infected with L. major. In these studies, the resistance to L. major is correlated with the development of Th1 CD4+ lymphocytes that produce high levels of IFN-g, a cytokine capable of activating macrophages to kill the intracellular forms of the parasite. On the other hand, susceptibility has been associated with the lack of IFN-g production and the presence of Th2 CD4+ lymphocytes that produce IL-4 which acts inhibiting the activation of macrophages12,18,23. There is, however, no report on infection of Swiss/NIH mice with L. ...
Abstract. Climatic, environmental, and demographic changes favor the emergence of neglected vector-borne diseases like leishmaniasis, which is spreading through dogs, the principle host of the protozoan Leishmania infantum. Surveillance of the disease in dogs is important, because the number of infected animals in an area determines the local risk of human infection. However, dog epidemiological studies are costly. Our aim was to evaluate the Emerging Diseases in a Changing European Environment (EDEN) veterinary questionnaire as a cost-effective tool in providing reliable, spatially explicit indicators of canine leishmaniasis prevalence. For this purpose, the data from the questionnaire were compared with data from two epidemiological studies on leishmaniasis carried out in Greece and Cyprus at the same time using statistical methods and spatial statistics. Although the questionnaire data cannot provide a quantitative measure of leishmaniasis in an area, it indicates the dynamic of the disease;

Cutaneous Leishmaniasis Drugs Market Size And ForecastAccording to Verified Market Research, the Global Cutaneous Leishmaniasis Drugs market was valued at USD 40.5 Million in 2018 and is projected to reach USD 56.1 Million by 2026, growing at a CAGR of 4.23% from 2019 to 2026.
The early events of leishmania infection are important in determining control or evolution of the disease. It is well known that the cure of leishmaniasis depends on the appropriate activation of the parasitized macrophages by IFN-γ secreted by Th1 lymphocytes, under the influence of IL-12 and IL-18 (27). When the protozoan encounters a favorable environment for producing Th2 cytokines, such as IL-4, IL-10 and IL-13, which are natural antagonists of the Th1 immune response, the multiplication of leishmania is enhanced and infection evolves into the disease (15, 16, 18, 27). IgE antibodies are produced in the Th2 immune response and have been used in serodiagnosis and also as indicators of the disease activity in toxoplasmosis, cerebral malaria, and VL (2, 22, 28).. CL is a clinical form of the leishmanial infection characterized by an evident Th1 type of immune response, documented by lymphocyte proliferation and IFN-γ secretion. However, high levels of parasitic-specific serum IgE without ...
A research team at The University of Texas at El Paso is one step closer to developing an effective human vaccine for cutaneous leishmaniasis, a tropical disease found in Texas and Oklahoma, and affecting some U.S. troops stationed in Afghanistan and Iraq.. UTEP biological sciences doctoral student Eva Iniguez; her mentors Rosa Maldonado, Ph.D., and Igor Almeida, Ph.D.; and their teams and collaborators in Liverpool (Alvaro Acosta-Serrano, Ph.D.) and Saudi Arabia (Waleed Al-Salem, Ph.D.), recently published their research findings in PLOS Neglected Tropical Diseases, the first journal solely devoted to the worlds most neglected tropical diseases.. Leishmaniasis is caused by the protozoan leishmania parasites, which are transmitted by the bite of infected female phlebotomine sandflies - flies that are three times smaller than a mosquito. According to the World Health Organization, there are an estimated 700,000 to 1 million new cases annually, and they cause 20,000-30,000 deaths each year. The ...

Background. Leishmaniasis is caused by the Leishmania parasite, and transmitted by infected phlebotomine sandflies. Of the two distinct clinical syndromes, cutaneous leishmaniasis (CL) affects the skin and mucous membranes, and visceral leishmaniasis (VL) affects internal organs. Approaches to prevent transmission include vector control by reducing human contact with infected sandflies, and reservoir control, by reducing the number of infected animals.. Objectives. To assess the effects of vector and reservoir control interventions for cutaneous and for visceral leishmaniasis.. Search methods. We searched the following databases to 13 January 2015: Cochrane Infectious Diseases Group Specialized Register, CENTRAL, MEDLINE, EMBASE, LILACS and WHOLIS, Web of Science, and RePORTER. We also searched trials registers for ongoing trials.. Selection criteria. Randomized controlled trials (RCTs) evaluating the effects of vector and reservoir control interventions in leishmaniasis-endemic regions.. Data ...
Canine leishmaniasis (CanL) is a vector-borne disease caused by|i| Leishmania infantum|/i| and is transmitted by female phlebotomine sand flies primarily between animals and secondarily to humans. The course of infection may be different from one individual dog to another, ranging from spontaneous cure to acute evolution that leads to death, if proper management and therapy are not adopted. A parasitological cure is rarely achieved and clinical recurrences in CanL are frequent. Vaccination associated with the use of topical insecticides is undoubtedly the most effective form of prevention and control of the disease. In order to integrate the most important scientific knowledge of the literature in one objective publication, this review proposes a short overview of the main points of CanL.
The sensitivity and specificity of lymph node and bone marrow smear microscopy for the diagnosis of Leishmania infantum-infected dogs was evaluated in 79 dogs with leishmaniasis (Group A), 52 asymptomatically infected dogs (Group B), and 44 healthy noninfected dogs (Group C). Light microscopy examination included 10 to 1,000 oil immersion fields, and the density of Leishmania amastigotes was scored by a 0 to +6 scale. Using polymerase chain reaction as the gold standard, the specificity of lymph node and bone marrow cytology was 100%, whereas sensitivity ranged from 7.8% to 92.6%, being significantly higher in Group A compared with Group B. The amastigote scores were also significantly higher in Group A compared with Group B. These results indicate that lymph node and bone marrow cytology is a highly sensitive and specific method for the diagnosis of canine patent leishmaniasis, whereas its sensitivity is relatively low in asymptomatic infections.
OBJECTIVES. Pentavalent antimonials, alone or in combination with allopurinol, are the most frequently drugs used in the management of canine leishmaniasis (CL). Despite clinical remission occurs in a majority of cases, most dogs remain parasitologically infected and relapses are frequent. It should be considered that if a clinical but not parasitological cure is achieved, dogs may act as a reservoir of the disease. Moreover, side effects and development of resistances must be considered. Amphotericin B desoxycholate (AmB) is a powerful leishmanicidal agent. Its use in dogs with CL it not very extended, due in part to its nephrotoxicity. Recently the initial effectiveness and toxicity of a new protocol using a lipid emulsion of AmB was assessed.2 The aim of this prospective study is to evaluate both, the initial and the long-term efficacy of this protocol in the treatment of dogs naturally infected with CL. MATERIALS. 14 dogs showing clinical signs of CL and diagnosed after visualization of ...
Genetic factors play a crucial role in host susceptibility or resistance to infectious diseases. Variations within the SLC11A1 gene were assessed in this study with respect to cutaneous leishmaniasis in Pakistan which has not been reported before from this region. A total of eight polymorphisms present in SLC11A1 gene were analyzed and their possible role in disease association and linkage was tested.. Six of these genetic variations (rs2276631, rs2290708, rs3731864, rs201565523, rs17235409 and rs17235416) have been analyzed before in various populations with regard to leishmaniasis. In addition to these six SNPs, two polymorphisms, rs2695342 (825A/G) in exon 9 and rs17215556 (V443A) in exon 13, not investigated previously for their role in cutaneous leishmaniasis, were also included. The SNP rs2695342 (825A/G) in exon 9 alters the codon GCA to GCG. The resultant mutation is synonymous with no change in the amino acid alanine. Only the GG genotype was observed in all samples (cases and controls) ...
The Biological and Clinical Basis of Visceral Leishmaniasis, 978-3-639-37451-3, Leishmaniasis is prevalent through out the tropical and sub-tropical regions of Africa, Asia, the Mediterranean, Southern Europe (old world) and South and Central America (new world). It is estimated that approximately 12 million people are currently infected and a further 367 million are at risk of acquiring Leishmaniasis in 88 countries, 72 of which are developing countries and 16 of them are among the least developed in the world. The estimated incidence is 2 million new cases each year of which 0.5 million are of VL and 1.5 million are of CL. Immune system plays an important role in protection against all forms of Leishmaniasis. Protection is mediated mainly through the ability of the CD4 cells to converge into Th1 effectors which mainly produce many cytokines such as IL-2, IFN-γ and TNF-β. The need for an immunological strategy to be employed in VL control programme is also felt due to the fact that a large number of
Cutaneous leishmaniasis is an infection caused by various species of Leishmania protozoa and is endemic in more than 70 countries throughout Latin America, Asia, Middle-East and southern Europe. The global number of reported cases has increased in the past decades because of improved diagnosis and case notification, but also because of drug resistance and inadequate vector control as a result of urbanisation and deforestation.1Leishmania parasites are transmitted by sandflies belonging to either Phlebotomus spp (Asia, Europe, Middle-East and North-Africa) or Lutzomya spp (Central and South America). The ecological context of the transmission cycles between the Old World (i.e., Africa, Asia and Europe) and the New World (i.e., the Americas) is different. New World cutaneous leishmaniasis is mostly associated with forests, whereas an open semi-arid climate is the transmission environment for Old World cutaneous leishmaniasis. There are 17 different Leishmania species that can cause different ...

Main description: This book discusses recent developments in several laboratories studying leishmaniasis. Sequencing of the human genome, as well as of the leishmania genome, has led to significant advances in our understanding of host-immune responses against leishmania, and mechanisms of infection-induced pathology, which is responsible for morbidity and mortality. Pathogenesis of Leishmaniasis focuses on the latest basic research into leishmaniasis, but also addresses how advances in understanding can be applied to prevention, control and treatment of what the WHO has classified a neglected tropical disease.. ...
In areas where the known vector is a sandfly, deltamethrin collars worn by the dogs has been proven to be 86% effective.[16] The sandfly is most active at dusk and dawn; keeping dogs indoors during those peak times will help minimize exposure. Unfortunately, there is no one answer for leishmaniasis prevention, nor will one vaccine cover multiple species. Different virulence factors have been identified for distinct Leishmania species, and there are profound differences in the immune mechanisms that mediate susceptibility/resistance to infection and in the pathology associated with disease.[17] In 2003, Fort Dodge Wyeth released the Leshmune vaccine in Brazil for L. donovani (also referred to as kala-azar in Brazil).[18] Studies indicated up to 87% protection.[19] Most common side effects from the vaccine have been noted as anorexia and local swelling.[19] The president of the Brazil Regional Council of Veterinary Medicine, Marcia Villa, warned since vaccinated dogs develop antibodies, they can ...

Methods: This study was an ecological study using existing data related to the rural districts of Sabzevar county. Data during the period of 2011 to 2017 were obtained from the health deputy of this county. In this study, the segmented regression model was applied to evaluate the time trend of cutaneous leishmaniases CL. Joint point software was used for time series analysis. Results: A total of 1912 (CL) cases occurred in Sabzevar county from 2011 to 2017, with an incidence rate of 93.61 per 100,000. The highest and lowest observed incidence rates were in 2011(25 per 10,000 persons) and 2015 (3.24 per 10,000 persons) respectively. The annuall incidence of CL in the region under study was decreased, and APC was equal to -22.40. Time series analysis using segmented regression by rural districts showed that there was a Change point in the trend of incidence of
Visceral leishmaniasis is spread by sandfly bites. This type of leishmaniasis affects the internal organs, usually the spleen, liver and bone marrow.
Leishmaniasis is recognized by the World Health Organization as a neglected disease - one that has particular impact on the worlds most vulnerable populations, but receives little funding or public attention. With a mandate to develop drugs for such neglected diseases, the Institute for OneWorld Health has made leishmaniasis a priority for its drug development efforts.. Leishmaniasis is a parasitic disease transmitted by the bite of a sand fly, a tiny and often unrecognized threat. Leishmaniasis is found in 88 countries, and the disease afflicts over 12 million worldwide. Four major forms of the infection are known, but the most lethal form of the disease is visceral leishmaniasis. Also known as black fever or kala azar, visceral leishmaniasis infects 500,000 annually, and is responsible for 60,000 deaths each year. Ninety percent of all cases occur in five countries: India, which has the greatest burden of the disease, Bangladesh, Brazil, Nepal and Sudan. Left untreated, the visceral ...

Leishmaniasis is a tropical disease affecting around 12 million people worldwide with a further 350 million people at risk. Two million new cases are identified every year with an estimated 60,000 fatalities. Treatments have changed little in the past century and often patients are treated with increasingly ineffective and highly toxic drugs, thus highlighting the requirement for safer and more effective medication. Protein kinases have attracted a lot of attention as potential targets for treating a variety of human diseases, including leishmaniasis. LmxMPK2 is a mitogen-activated protein (MAP) kinase homologue in Leishmania mexicana that is expressed in both the amastigote and promastigote life stages. Generation of homozygous gene knock out mutants revealed a reduction in cell proliferation and a range of morphological alterations with cells showing multiple flagella, kinetoplasts and nuclei, lobed cell bodies, spiked posterior ends and division furrow ingression from the poster ior end. ...

For example, Kaye and Smith are working together on developing a therapeutic vaccine for leishmaniasis, targeting a different arm of the immune system to that focused on by most previous research (CD8 rather than CD4 T cells) and using new vectors to deliver the vaccine. It is one of just two second-generation vaccines in development for leishmaniasis and they hope to start phase I trials this year.. We need to protect the drugs we have, says Kaye. We only have three leishmaniasis drugs and there is already resistance to the commonest drug in parts of India where visceral leishmaniasis is endemic. Second-line drugs are being used but while these are very effective, they do have some side-effects and are costly. A therapeutic vaccine given in combination could help protect the drugs lifetimes. Also, we could use lower doses or a lower number of doses or expect greater compliance, which would all help to minimise resistance.. Underpinning this work are years of basic research. Kaye himself ...
