American Cutaneous Leishmaniasis (ACL) is a zoonosis caused by Leishmania protozoa. The ACL chemotherapy available is unsatisfactory motivating researches to seek alternative treatments. In this study, we investigated the action of biogenic silver nanoparticle (AgNp-bio) obtained from Fusarium oxysporium, against Leishmania amazonensis promastigote and amastigote forms. The AgNp-bio promastigote treatment results in promastigote death leading to apoptosis-like events due an increased production of reactive oxygen species (ROS), loss of mitochondrial integrity, phosphatidylserine exposure and damage on promastigotes membrane...

BACKGROUND: Protozoan parasites from the genus Leishmania cause broad clinical manifestations known as leishmaniases, which affect millions of people worldwide. Cutaneous leishmaniasis (CL), caused by L. major, is one the most common forms of the disease in the Old World. There is no preventive or therapeutic human vaccine available for L. major CL, and existing drug treatments are expensive, have toxic side effects, and resistant parasite strains have been reported. Hence, further therapeutic interventions against the disease are necessary...

Leishmania lipophosphoglycan (LPG) is a key virulence factor, initiating inflammation resulting in cutaneous lesions. LPG is capped by various oligosaccharides. How these glycans are recognized and how they alter the course of Leishmania infection is poorly understood. Previous studies synthesized α-1,2-trimannose cap sugars on latex beads demonstrated that C57BL/6 mice co-inoculated with L. major and trimannose-coated beads produced significantly higher levels of IL-12 p40 and other pro-inflammatory, type 1 cytokines compared L...

Antimony is the first line drug for treating American tegumentary leishmaniasis (ATL) in Brazil. In this country, Leishmania braziliensis causes at least three distinct forms of disease: localized cutaneous (CL), mucosal (ML) and disseminated leishmaniasis (DL). All forms can be found in Corte de Pedra, Northeast Brazil. ML and DL respond poorly to antimony, in contrast to CL. The L. braziliensis population causing ATL in Corte de Pedra is genetically very diverse, with strains of the parasite associating with the clinical form of leishmaniasis...

Studies have demonstrated pyrazinamide's efficacy against stages of the parasite which causes cutaneous leishmaniasis. Although pyrazinamide is widely distributed to most fluids and tissues, the drug distribution that reaches the skin is unknown. The aim of this study was to investigate pyrazinamide pharmacokinetics in rat dermal tissue by dermal microdialysis. Skin pharmacokinetics were assessed by implanting a linear microdialysis probe in the dermis of ten rats. Additionally, blood samples were collected for assessing plasma pharmacokinetics...

BACKGROUND: This study was designed to detect whether there is a correlation between in vitro susceptibility of field isolates of Leishmania major and the clinical outcomes of meglumine antimoniate (Glucantime®) therapy, the mainstay of cutaneous leishmaniasis treatment in Iran. METHODS: Forty-three patients infected with L. major were enrolled in this study from October 2009 to March 2010 and categorized as responsive or unresponsive to Glucantime® treatment after receiving the appropriate therapy...

BACKGROUND: Cutaneous Leishmaniasis (CL) is endemic in many tropical and subtropical regions of the world. Due to the prolonged duration of therapy, adverse effect and resistance to current drugs in the treatment of CL, the discovery of novel, efficient, and safe leishmanicidal drugs is required. The aims of the present study was to synthesis of new compounds based on the active compounds of 5-(5-nitrofuran-2-yl)- and 5-(5-nitrothiophen-2-yl)-1,3,4-thiadiazole bearing the linear amino alcohol of 3-aminopropan-1-ol in the C-2 position of thiadiazole ring and evaluation of their activity against the promastigote and amastigote forms of Leishmania major...

BACKGROUND: Several controlled and uncontrolled studies addressing azole antifungal drugs for cutaneous and mucosal leishmaniasis have been published with inconclusive results. We conducted a systematic literature review of studies evaluating the efficacy and toxicity associated with azole therapy for tegumentary leishmaniasis. METHODOLOGY: PRISMA guidelines for systematic reviews and the Cochrane manual were followed, and the review methodology was registered (PROSPERO; CRD42016048668)...

Meglumine Antimoniate (MA), administered intramuscularly for 21 continuous days is the recommended treatment of leishmaniases in Ecuador. However, because of its toxicity and requirement for intramuscular injections, treatment is frequently abandoned before completion. In addition, therapeutic failure and reactivation are not uncommon. Here we evaluate the efficacy and safety of MA administered intralesionally (IL) in leishmaniasis recidiva cutis (LRC). LRC is a special clinical variant of cutaneous leishmaniasis, characterized by reactivation at the edges of a primary cured lesion, presenting with active papules around the scar...

Leishmaniasis is a vector-borne disease caused by infection by parasites from the genus Leishmania. Clinical manifestations can be visceral or cutaneous, the latter mainly being chronic ulcers. This work was aimed at evaluating Calliphoridae Lucilia sericata- and Sarconesiopsis magellanica-derived larval excretions and secretions' (ES) in vitro anti-leishmanial activity against Leishmania panamensis. Different larval-ES concentrations from both blowfly species were tested against either L. panamensis promastigotes or intracellular amastigotes using U937-macrophages as host cells...

BACKGROUND: Cutaneous leishmaniasis is one of the highly prevalent endemic diseases in the Middle East and North Africa. Many treatment modalities have been recommended for this condition but success rates remain limited. Herbal remedies have also been used for treatment but evidence-based clinical trials with these products are sparse. In-vitro and in-vivo studies have shown the anti-leishmanial and curative effects of extract of fruits and leaves of Juniperus excelsa (J. excelsa). The aim of this study was to determine the efficacy of topical J...

Cutaneous leishmaniasis (CL) is spread worldwide and is the most common manifestation of leishmaniasis. Diagnosis is performed by combining clinical and epidemiological features, and through the detection of Leishmania parasites (or DNA) in tissue specimens or trough parasite isolation in culture medium. Diagnosis of CL is challenging, reflecting the pleomorphic clinical manifestations of this disease. Skin lesions vary in severity, clinical appearance, and duration, and in some cases, they can be indistinguishable from lesions related to other diseases...

Cutaneous leishmaniasis (CL) is the most common clinical form of American tegumentary leishmaniasis caused by Leishmania (Viannia) braziliensis. CL is associated with a strong Th1 immune response. This exacerbated inflammatory response is correlated with severity of disease and delays the healing time of the ulcer. The fourth-generation immucillin derivative (DI4G), a potent inhibitor of purine nucleoside phosphorylase, has been proposed as a promising agent in the treatment of diseases associated with T cell activation...

Cutaneous leishmaniasis is the most common form of lesihmaniasis, caused by Leishmania major and is spread by the bite of a sandfly .This species infects the macrophages and dendritic cells Due to multi-drug resistance, there is a need for a new therapeutic technique. Recently, a novel molecular motor of Leishmania, Myosin XXI, was classified and characterized. In addition, the drug resistance in this organism has been linked with the overexpression of ABC transporters. Systems biology aims to study the simulation and modeling of natural biological systems whereas synthetic biology deals with building novel and artificial biological parts and devices  Together they have contributed enormously to drug discovery, vaccine design and development, infectious disease detection and diagnostics...

BACKGROUND: The mainstays of cutaneous leishmaniasis (CL) treatment, in several world regions, are pentavalent antimony (Sbv) compounds administered parenterally, despite their recognized toxicity, which requires frequent laboratory monitoring and complicates their use in areas with scarce infrastructure. As result of these drawbacks, the WHO Expert Committee on leishmaniasis has expanded the recommendations for the use of local therapies, including Sbv intralesional infiltration (IL-Sbv), as CL therapy alternatives even in the New World...
