Active clinical trials for "Leishmaniasis, Cutaneous"

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.

The purpose of the study is to evaluate the sensitivity and specificity of CL Detect, in subjects with suspected CL in Tunisia.

New point-of-care (POC) tests are needed and assessing the performance of these tests for cutaneous leishmaniasis (CL) in Afghanistan may help increasing the number of CL patients with access to accurate diagnosis, and enable prompt treatment. Simpler tests could improve treatment access and benefit patients and communities, by reducing the risk of sequelae and the risk of disease transmission. CLeishPOCAFG aims to advance the diagnosis of CL by using more accurate and field-amenable methods.

CL is public health in the Americas, diagnostic confirmation is required to start treatment, however current diagnostic methods have several limitations and its access is limited. Technical requirements of conventional molecular diagnostics and costs preclude their routine use in primary care facilities in rural areas. A recently developed method of Isothermal Recombinase Polymerase Amplification (RPA) targeting Leishmania kinetoplast DNA, has shown high accuracy in detecting Leishmania Viannia spp. We evaluated the diagnostic performance of the RPA-LF test in a laboratory reference center and field scenario with community participation.

Current standard therapies with chemotherapy (CT) for Cutaneous Leishmaniasis (CL) are expensive, toxic/allergenic, frequently ineffective, burdensome, and often unavailable. Thermotherapy is a clinically validated first line alternative for the treatment of Cutaneous Leishmaniasis in South America. However, current heat-delivery modalities are either too costly or lack governmental approval required to be made widely available to endemic areas. The investigators have adapted a reliable, safe, and low-cost heat pack for Cutaneous Leishmaniasis that the investigators have named the HECT-CL device. In this pilot study the investigators will enroll 25 patients who have either failed or are not candidates for pentivalent antimonies. The hypothesis states that the HECT-CL device demonstrates efficacy non-statistically inferior to estimates for current South American Pentavalent Antimonial cure rates (76%) while demonstrating basic safety and tolerability.

Cutaneous Leishmaniasis in Ethiopia causes severe dermatological mutilations. Forms that require systemic treatment are cLCL, MCL, and DCL. National guidelines recommend equally all drugs that are also used for VL treatment. Miltefosine is one of these recommended medications but remains underused due to scarcity of drugs. Outcomes of patients receiving miltefosine have never been documented systematically in Ethiopia until today. This is needed to provide evidence to advocate for increased access to miltefosine in Ethiopia, and to establish baseline data for future research on CL treatment options. The aim of this study is to document treatment outcomes of patients with cLCL, MCL, and DCL receiving systemic treatment using miltefosine within a routine care setting located in an endemic area in Ethiopia.

The performance of the CL Detect Rapid test will be tested in individuals with suspected cutaneous leishmaniasis in Ethiopia using both skin slit and dental broach samples against a combined reference of microscopy and PCR. Alternative sampling methods will also be evaluated.
