The treatment of leishmaniasis still relies on drugs with potentially serious adverse effects. Herein, we tested a topical formulation of bacterial cellulose (BC) membranes containing Diethyldithiocarbamate (DETC), a superoxide dismutase 1 inhibitor. Leishmania-infected macrophages exposed to BC-DETC resulted in parasite killing, without pronounced toxic effects to host cells. This outcome was associated with lower SOD1 activity and higher production of superoxide and cytokine mediators. Topical application of BC-DETC significantly decreased lesion size, parasite load and the inflammatory response at the infection site, as well as the production of both IFN-γ and TNF...

Leishmaniasis is caused by protozoan parasite of genus leishmania. Visceral leishmaniasis, diffuse cutaneous leishmaniasis, and atypical forms of cutaneous leishmaniasis are common in HIV-infected patients. Our patient presented with an obstructive mass in nasal cavity and was diagnosed as a case of mucocutaneous leishmaniasis. Spontaneous healing of lesions in HIV-infected patients is rare rather they are unresponsive to treatment and have frequent relapses, especially in patients with low CD4 count. However, in our patient, the lesion improved significantly after 2 months of highly active antiretroviral therapy and co-trimoxazole prophylaxis...

Cutaneous leishmaniasis is one of the important skin diseases with diverse clinical manifestations. With an incidence of 0.7-1.3 million cases annually, this disease is often reported from six countries, including Iran. Accordingly, the purpose of this study was to evaluate the anti-leishmanial effect of the three plant hydroalcoholic extracts including fleawort (Plantago psyllium L.), savory (Satureja hortensis L.) and tarragon (Artemisia dracunculus L.) on Leishmania major promastigotes. The hydroalcoholic extract from each plant was extracted and its anti-leishmanial effect was evaluated in different concentrations (100-1000 µg/ml) and at various hours (24, 48 and 72 h)...

Leishmaniasis is a spectrum of disease condition with considerable health impacts, caused by different species of Leishmania. This disease is currently endemic in 98 countries and territories in the world. There are many treatment modalities for cutaneous leishmaniasis. The use of topical terbinafine in the treatment of cutaneous leishmaniasis has recently been considered. Eighty-eight participants more than two years old with proven acute CL by a positive direct smear were randomly allocated to one of the two study arms: first group received meglumine antimoniate (Glucantime) 20 mg/kg/day intramuscular injection (IM) plus a placebo ointment (Mahan Vaseline) for 20 days...

Cutaneous leishmaniasis affects nearly 0.7 to 1.3 million people annually. Treatment of this disease is difficult due to lack of appropriate medication and the growing problem of drug resistance. Natural compounds such as coumarins serve as complementary therapeutic agents in addition to the current treatment modalities. In this study, we have performed an in-silico screening of the coumarin derivatives and their anti-leishmanial properties has been explored both in-vitro and in-vivo. One of the compounds (compound 2) exhibited leishmanicidal activity and to further study its properties, nanoliposomal formulation of the compound was developed...

Leishmaniasis is caused by parasitic protozoa of the genus Leishmania. Cutaneous leishmaniasis (CL) is endemic in Sri Lanka with over 3000 cases during the last decade and numbers are increasing. Treatment options available in Sri Lanka for CL include intralesional/intramuscular sodium stibogluconate and cryotherapy. Eight cases of treatment failure with standard therapy are reported from the Dermatology Clinic, Teaching Hospital Anuradhapura. Therapeutic regimes aim for clinical healing, these patients responded poorly to anti-leishmanial therapy, indicating the need for close monitoring, explore alternative treatment options and to investigate for drug resistance in parasites...

This study's main objective was to evaluate the action of larval therapy derived from Lucilia sericata and Sarconesiopsis magellanica (blowflies) regarding Leishmania panamensis using an in vivo model. Eighteen golden hamsters (Mesocricetus auratus) were used; they were divided into 6 groups. The first three groups consisted of 4 animals each; these, in turn, were internally distributed into subgroups consisting of 2 hamsters to be used separately in treatments derived from each blowfly species. Group 1 was used in treating leishmanial lesions with larval therapy (LT), whilst the other two groups were used for evaluating the used of larval excretions and secretions (ES) after the ulcers had formed (group 2) and before they appeared (group 3)...

We recently demonstrated that statins mediate protection against intracellular pathogens, Mycobacterium tuberculosis and Listeria monocytogenes in mice. Here, we investigated the immunomodulatory potential of simvastatin as a topical or systemic host-directed drug therapy in controlling inflammatory responses in an experimental mouse model of cutaneous leishmaniasis caused by Leishmania major (LV39). In an ear infection model, topical application of simvastatin directly on established lesions significantly reduced severity of the disease reflected by ear lesion size and ulceration...
