Efficacy of Topical Liposomal Form of Drugs in Cutaneous Leishmaniasis
Cutaneous LeishmaniasisLeishmaniasis with diverse clinical manifestations is caused by different species of Leishmania and is endemic in many countries. Although Cutaneous Leishmaniasis (CL) is a self-healing disease, but it takes a long time to heal. Pentavalent antimonials are still the first-line treatment of CL which needs multiple injections, are painful and as such not tolerated by most of the patients, in addition available treatments are not always effective and resistance is reported. Paromomycin sulfate (PM) reported to show anti-Leishmania activity against both CL and visceral leishmaniasis (VL) since 1960s. Therapeutic strategy with high efficacy is urgently needed especially for Anthroponotic Cutaneous Leishmaniasis (ACL). Liposomes are lipid bilayer molecules which entrap water-soluble molecules in their internal water compartment and water-insoluble ones into their lipid bilayers. Liposomes, in proper formulations and sizes, deliver drugs to the skin based on the similarity of the bilayers structure of lipid vesicles to that of natural membrane and target the macrophages within dermis. Several lipid-based formulations have been developed to treat experimental leishmaniasis. Recently different doses of liposomal formulation of PM and liposomal formulation of Glucantime were prepared and showed high efficacy in vivo against L. major infection in BALB/c mice. In this study the efficacy of liposomal formulation of PM or liposomal formulation of Glucantime in combination with systemic Glucantime in the treatment of ACL parasitologically proven patients will be evaluated. The clinical trial will be carried out according to the International approved GCP (Good Clinical Practice) guide lines.

Study of the Efficacy of Daylight Activated Photodynamic Therapy in the Treatment of Cutaneous Leishmaniasis...
Cutaneous LeishmaniasisThe aim of the project is to determine whether daylight activated photodynamic therapy is effective in treating cutaneous leishmaniasis caused by L. major and L. tropical. PDT is classically performed as a two-step procedure in which MAL application to the lesion constitutes the first step, and PpIX activation by light of appropriate wavelength from an artificial light source constitutes the second step. Based on the knowledge that red and blue light required to activate PpIX are part of the daylight spectrum, the investigators postulated that effective PpIX activation can be obtained by exposure of the MAL treated lesions to daylight thus substantially simplifying the PDT procedure by omitting the 3 hour incubation period and the subsequent exposure to artificial light. In accord, in a recent study the investigators showed that daylight-activated PDT (DA-PDT) was as effective as conventional MAL-PDT in treating precancerous actinic keratoses lesion. Furthermore the investigators found that DA-PDT is significantly less painful than conventional MAL-PDT. The investigators now propose to study the efficacy of DA-PDT in the treatment of cutaneous leishmaniasis. DA-PDT has obvious advantages to conventional leishmania treatment forms: As opposed to most of the available treatment options, DA-PDT is a self-administered procedure that does not require the assistance of medical personnel. Secondly, judged by our experience with MAL-PDT, only few treatment sessions are required for effective parasite killing as opposed to the prolonged procedures usually required for treatment of leishmaniasis. Third, PDT has the far the best safety profile of all available treatment options.
Short Course of Miltefosine and Antimony to Treat Cutaneous Leishmaniasis in Bolivia
Cutaneous LeihmaniasisThe combination of a half-course of miltefosine and a half-course of antimony will be evaluated for efficacy and tolerance. The combination of miltefosine and antimony is chosen because these are now the two standard agents in Bolivia, and in vitro the combination was additive to mildly synergistic against a standard leishmania strain.

A Clinical Study to Develop an Uninfected Sand Fly Biting Protocol
LeishmaniasisCutaneous1 moreThe disease leishmaniasis mainly occurs in hot and tropical countries, affects millions of people and causes around 20,000 deaths across the world every year. Leishmaniasis is caused by the Leishmania parasite and is transmitted by sand flies. The parasite is tiny and not visible to the naked eye, whereas the particular sand fly is visible but small and inconspicuous. There are different types of leishmaniasis around the world and some can be very serious. They affect the skin (cutaneous leishmaniasis) or the internal organs of the body (visceral leishmaniasis). Some of the milder forms will produce skin problems which will be localised, whilst other forms of leishmaniasis will cause widespread skin changes. The skin lesions of cutaneous leishmaniasis can be disfiguring if left untreated. There are some treatments for leishmaniasis available but many of them are not easy to use or don't work well. Therefore new treatments and vaccines are needed that prevent or work against leishmaniasis. A solution being adopted for other diseases, which the investigators now wish to adopt for leishmaniasis is to develop a 'Controlled human infection model' (CHIM). These models involve deliberate exposure of individuals to an infection, in order to better understand how the disease works and to test potential vaccines and treatments. They have contributed vital scientific knowledge that has led to advances in the development of drugs and vaccines. This is an initial study using uninfected (disease-free) sand flies, taking place at the University of York. The information from this study will help us to develop a model in the future using infected sand flies so that the investigators can assess any future vaccines against Leishmaniasis. The investigators will also hold a focus group after the sand fly biting study to explore the experiences of individuals taking part in this study.
Documentation of Patient Outcomes for SSG/Allopurinol Combination Treatment in Ethiopia
Cutaneous LeishmaniasisOutcomes of patients receiving SSG and Allopurinol combination have never been documented systematically in Ethiopia. Therefore, it is not known how effective this combination is. This study will provide evidence to help clinicians make the best choice regarding treatment for complicated cutaneous leishmaniasis (CL) cases. Due to diversity in host-pathogen interactions across the different CL forms, early immunological correlates associated with treatment responsiveness and unresponsiveness could help treatment recommendation and provide us with the basis to develop new diagnostic and treatment strategies. This study aims to document treatment outcomes of patients with cLCL, MCL, and DCL receiving systemic treatment using SSG and Allopurinol combination within a routine care setting located in a highly endemic area in Ethiopia.

Diagnosis of Cutaneous Leishmaniasis Using the CL-detect Rapid Test in Travelers and Migrants in...
Cutaneous LeishmaniasesCutaneous Leishmaniasis (CL) is a neglected tropical disease which is increasingly seen in travelers and migrants evaluated in travel clinics of non-endemic countries. Various CL species are present in different parts of the world, and these different species vary in severity, prognosis and therapeutic approaches. At ITM, diagnosis of CL in suspected patients is done using a skin biopsy, analyzed by diagnostic PCR, and species typing PCR. This method is invasive, and diagnosis is often delayed for days to weeks. The new antigen-based CL Detect Rapid Test uses dental broach sampling and has results within 30 minutes. Dental broach samples left over from the Cl Detect Rapid test may still be used for PCR including species typing. How well the CL Detect Rapid Test performs in the varied population of a travel clinic and whether it is possible to use dental broach sampling for further PCR tests in this population needs to be evaluated The aim of this study is to study the performance of the CL Detect Rapid Test and whether dental broach sampling can replace skin biopsy for CL at ITM.
