Filter by:This trial is designed to assess the therapeutic efficacy and safety of CHAd63-KH, a new candidate Leishmania vaccine, in patients with persistent PKDL. 100 participants will be randomly assigned (50 participants in each arm) to receive placebo or ChAd63-KH 7.5 x10(10)vp. Doses will be administered at a single time point.
This study will evaluate how the test medicine DNDI-0690 is taken up and broken down by the body and will also look at the safety and tolerability of the test medicine after a single dose. This is the first time the test medicine DNDI-0690 will be administered to humans.
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.
Cure rate for L braziliensis bolivian CL has been 70%-80% for standard systemic and local monotherapies. It would benefit patients if cure rates could be consistently >90%, so testing a combination of two treatments is proposed. The most attractive systemic therapy is the only oral agent, miltefosine during 28 days, and the most attractive local therapy is application of Paromomycin cream for 28 days.
Determine the sensitivity and specificity of the FDA-cleared CL Detect™ Rapid Test in Peru, using a test procedure that was modified from that described in the device instructions to optimize these parameters for the detection of Leishmania species identified in Peru.
Bolivian cutaneous leishmaniasis due to Leishmania braziliensis was treated with the combination of miltefosine (150 mg/day for 28 days) plus intralesional pentamidine (120 ug/mm2 lesion area on days 1, 3, and 5).
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.
Leishmaniasis is considered by the WHO as emerging and uncontrolled diseases. They are the second leading cause of death and the fourth leading cause of morbidity in tropical diseases. Leishmaniasis is parasitic reticulo-endotheliosis, the pathogenic agent of which is a flagellated protozoan belonging to the genus Leishmania. It is estimated that there are about 2 million new cases per year. Effective treatments against visceral leishmaniasis are few and resistance problems appear. To date, only a canine vaccine is available protecting dogs from the development of canine leishmaniasis to L. infantum. In man, in parallel clinical cases, leishmaniasis is characterized by a large number of asymptomatic carriers. This is the case in the Alpes-Maritimes where 50% of the inhabitants of the hinterland of Nice are carriers of the parasite. the investigators wish to study the protective immune response to the parasite and more particularly to the asymptomatic carriers. Indeed, these patients were infected with the parasite and did not develop the disease. Understanding the protective immune response in these patients against the parasite is therefore paramount in the development of a human leishmaniasis vaccine. For this purpose, the investigator wants to make an ex vivo study of the immune response of lymphocytes coming from asymptomatic carriers after stimulation by Leishmania vaccine peptides. It also wants to describe the immune response, after stimulation by these peptides, in the lymphocytes of subjects asymptomatic carriers and lymphocytes from subjects not infected with the parasite and comparing them. This study is unicentric and non-randomized. It wishes to recruit 20 asymptomatic carriers of L. Infantum and 10 uninfected subjects. They will be selected from our database. A simple blood sample will be taken. After verification by quantitative PCR and western blotting of their status towards leishmaniasis, the team will divide them into two groups (asymptomatic or healthy). Then the blood samples will be sent to the team of Jean Loup Lemesre of the Laboratory INTERTRYP - UMR177 of the IRD in Montpellier. ELISPOT analysis and assay of cytokines and proteases to describe the immune response of the two groups and to compare them. In addition, cell typing will be performed by flow cytometry to determine the type of lymphocytes involved in the immune response against Leishmania peptides. HLA typing will also be performed to validate the HLA coverage of the peptides tested. Finally, an analysis of the transcryptome will be carried out, which will allow to identify the differential expression of genes and metabolic pathways involved in the immune response and thus to understand how asymptomatic people can control the infection.
A clinical trial to asses efficacy and safety of Transition-state Analog Inhibitor of Human Purine Nucleoside Phosphorylase for topical use associated standard antimonial in the treatment of Cutaneous Leishmaniasis in Bahia, Brazil.
This study evaluates the effect of clean wound management and dressing on complex zoonotic cutaneous leishmaniasis caused by L. major in the MENA region (Algeria). The patients will participate in the wound dressing themselves. The objective is to determine the amount of patients that can avoid systemic chemotherapy with pentavalent antimony which is compulsory for patients with complex CL lesions. In Algeria, this requires expensive hospital care because of the eventual toxic side effects of Sb(V).
