Filter by:The 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.
This is a phase II/III open, comparative dose trial to find the lowest single dose of AmBisome for the treatment of primary, symptomatic visceral leishmaniasis(VL), in HIV negative patients. In this trial, the minimum effective dose will be determined in a sequential step, dose escalation design, which minimises the number of patients exposed to low, potentially inadequate doses and provides contemporaneous comparative data against the manufacturer's recommended dose schedule in this indication.
This study was designed to evaluate the effect of low doses of pentavalent antimony (meglumine antimoniate) to treat cutaneous leishmaniasis ulcers in patients older than 65 years. The hypothesis is that older patients may have a positive response with a lower dose of pentavalent antimony, avoiding the frequent adverse events observed with the standard dose. The design is that of an open uncontrolled trial enrolling 20 patients infected with the parasite Leishmania braziliensis in an endemic area of the State of Bahia, Brazil. The endpoint of cure or therapeutic failure will be evaluated at the third month of follow-up after treatment to avoid the impact of spontaneous cure as a confounding factor.
The objective of the project is to study the pathogenesis of Leishmania tropica infection in a focus of infection, to learn about relationship of infection in humans with ecological factors such as infection in hyraxes reservoir hosts and vector sandflies
The objective of this study is to determine the effectiveness and toxicity of WR 279,396, a topical cream for the treatment of cutaneous leishmaniasis. This study is to be conducted with a placebo control under double-blind conditions in a local population group in Tunisia where leishmaniasis is endemic.
The overall objective of this trial is to identify a safe and effective combination, (coadministration) short course treatment for the treatment of visceral leishmaniasis which could be easily deployed in a control programme and will reduce the risk of parasite resistance occurring. Safety and tolerability should be such that the combination can be easily deployed.
The adequate treatment of the American tegumentary leishmaniasis is crucial since the disease, differently from the caused by the Old World species, is painful and not self-healing and may lead to the disfiguring mucosal involvement. So far, pentavalent antimony compounds have been considered the treatment of choice for cutaneous leishmaniasis (CL), however, these drugs present high frequency of side effects and important disadvantages as parenteral administration and need for careful renal and cardiac monitoring. Azithromycin is a macrolide antibiotic, non-expensive, largely commercially available that has shown in-vitro and in vivo activity against different species of Leishmania. The main objective of this study is to evaluate the efficacy and safety of oral azithromycin for the treatment of CL. The efficacy of oral treatment of azithromycin 500 mg/day for 20 days is going to be compared with the standard treatment of intramuscular injections of 20 mg/Kg/day of pentavalent antimonials (Glucantime®) for 20 days in patients with CL from two endemic regions of Brazil: the metropolitan region of Belo Horizonte and Montes Claros (MG)in the southeast Brazil and in Corte de Pedras (Bahia), Northeastern Brazil. The patients follow up lasts for 12 months.
Leishmanias is a disease caused by the bite of sandflies and is found in many parts of the world including the Europe, Southwest Asia, Africa and the Middle East. This disease is a threat for military soldiers in areas where this disease is found. Sodium stibogluconate (SSG) or Pentostam (Glaxo Smith Kline, United Kingdom) is an Investigational New Drug (IND) product used by the Department of Defense for over 20 years to treat cutaneous, mucosal and viseral leishmanias. This drug is not licensed for commercial use in the United States because of very limited need for the product in the U.S.A. The objective of this protocol is to provide sodium stibogluconate for the treatment of cutaneous leishmaniasis and mucosal leishmaniasis (pentavalent antimonials curently considered the drug of choice for these infections) Provide sodium stibogluconate as a second line treatment for viscerotropic and visceral leishmaniasis (liposomal amphotericin is the drug of choice for these types as it is FDA approved for vusceral leishmaniasis).
The primary objective of this protocol is to treat laboratory confirmed cutaneous leishmaniasis with WR 279,396 in military health care beneficiaries. In this study "cutaneous leishmaniasis" is defined as Old World Leishmaniasis if acquired in the Southwest Central Asia/Middle East.

This drug is not licensed for commercial use in the United States because of very limited need for the product in the U.S.A. The primary objective of this protocol is to collect safety data on the use of Pentostam for treatment of laboratory-confirmed leishmaniasis with SSG 20mg/kg/d IV for 10 days or 20 days and visceral and mucocutaneous leishmaniasis with SSG 20mg/kg/d IV for 28 days. Due to low enrollment, the protocol was later amended in version 11 submitted 19May2010 in serial no. 0096) to remove the efficacy objective and only collect safety data for enrolled subjects. Prior to this amendment, data were entered on case report forms (CRFs). Per the Sponsor's discretion, CRFs were no longer required and protocol-specified treatment details and safety assessments were recorded in the patients' medical records (study file) only. No data entry or statistical analyses of patient data was conducted.
