Active clinical trials for "Leishmaniasis"

Primary Objectives: Assess whether CL (caused by Leishmaniasis major) lesions treated with WR279396 improved the cosmetic outcome compared with no treatment (natural healing)

Cutaneous 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.

To collect pilot data on the prevalence and incidence of asymptomatic Leishmania donovani infection in HIV infected individuals in a visceral leishmaniasis (VL)-HIV endemic region to inform the feasibility of a larger study exploring a screen and treat strategy for VL in HIV co-infected individuals in East-Africa (Ethiopia).

This study is a prospective observational study in which patients undergoing treatment for leishmaniasis with miltefosine (Impavido) in the US and who weigh > 75 kg can volunteer to provide information about their clinical response to treatment up to 6 months after the start of treatment.

According to recent estimates by the World Health Organization (WHO) on eastern Africa, not all visceral leishmaniasis (VL) cases reported are confirmed by a laboratory test, probably due to limited access to accurate diagnostic tests and poor reporting. The main approach for VL diagnosis involves antibody detection using the rK39 rapid diagnostic test (RDT) and alternatively the direct agglutination test (DAT) to confirm clinically suspected cases. Suspected cases with negative rK39 RDT and/or DAT results are referred to facilities where examination of tissue aspirate (spleen, bone marrow, lymph node) by microscopy is available. Unfortunately, the diagnostic performance of rK39 in eastern Africa is suboptimal, particularly in settings with a high VL/HIV co-infection rate. A recently developed RDT, based on the recombinant antigen rK28, may overcome this problem, with studies reporting better performance than the rK39. However, data are not definitive, as studies comparing rK28 RDTs with rK39 RDT are limited. Another recently developed RDT detects immunoglobulin G1 (IgG1) specific to Leishmania and has shown promising results in the Indian subcontinent. This study aims to undertake a multi-country assessment of the performance of rK28 and IgG1 RDTs, as compared to the currently used rK39 RDT.

HIV patients are likely to suffer from opportunistic infections, in absence of highly active retroviral therapy. This happens due to lack of awareness of HIV status among patients or unresponsive to anti retroviral drugs. This study is for the prevalence of AIDS defining OIs among treatment naive HIV patients.

This study is a single-site trial assessing the specificity of CL Detect™ Rapid Test versus the gold standard for Leishmania diagnosis in the US which is microscopic identification of Leishmania amastigotes in a stained lesion sample. Subjects will be patients who present for dermatology consultation with a primarily ulcerated lesion. After informed consent is obtained and the subject is screened for eligibility, 2 diagnostic samples will be collected from the subject's lesion in the following order: 1) one sample will be obtained with a dental broach for use with the CL Detect™ Rapid Test and 2) a second sample will be obtained by scraping for use in the microscopic identification of amastigotes. Samples will be analyzed by microscopy and CL Detect™ Rapid Test. The CL Detect™ Rapid Test will be performed by different operators who are clinical staff members. These staff members, blinded to each other's results, will evaluate the samples from each method independently. Each of the 150 study subjects will be followed administratively to the point where a diagnosis is established (if possible) for their tested lesion, even if that diagnosis is not cutaneous leishmaniasis (CL). If a specific diagnosis cannot be determined for a non-CL lesion, the investigator will assign a "likely etiology" (eg, infectious, oncological, immunological, vascular, or "undetermined/other" origin). Based on the diagnosis determined for each lesion, subjects will be referred for appropriate treatment.

This study will examine why some people who become infected with the leishmaniasis parasite develop skin lesions and others do not. The parasite that causes leishmaniasis is transmitted by the bite of a sandfly. It can cause skin lesions that may persist for several months, spread to other parts of the body, and become infected with bacteria. Treated with medicine, leishmaniasis can be cured completely. People 1 year of age and older who live in the Mali villages of Kemena or Sougoula may be eligible for this study. Participants are injected with a small amount of inactive parasites into the skin of their arm. People who have a reaction to the test, and thus have been exposed to the parasite, are examined for skin lesions. Their lesions, if any, are evaluated and treated, and their participation in the study ends. Participants who do not react to the skin test are examined for skin lesions every month for 5 months. Those who are 18 years of age or older and have mild leishmaniasis skin lesions may have a small amount of fluid injected into a lesion in order to remove parasites for laboratory analysis. Patients' lesions may be photographed to compare what they look like before and after treatment. Lesions are treated with an ointment containing an antibiotic and a disinfectant twice a day for 20 days. The lesions are examined 1 and 3 weeks after treatment is completed to see if the disease has been cured. A few months later, the skin test is repeated to determine whether the person has been exposed to parasites over the past year. A blood sample may be drawn from some participants, depending on whether they have a reaction to the second skin test and whether they have developed skin lesions. The sample is drawn only from patients 18-65 years of age. Some blood drawn for the study may be used for genetic tests.

Clinical, epidemiological, therapeutic and microbiological investigation of an outbreak of cutaneous Leishmaniasis that occurred among military personnel in French Guiana in 2020.

This is an expanded access treatment protocol designed to provide a topical cream treatment option to military health care beneficiaries with parasitologically confirmed uncomplicated Cutaneous Leishmaniasis.
