Filter by:A randomized controlled pilot trial with the aim of identifying the dose of liposomal amphotericin B associated with the highest cure rate in Cutaneous Leishmaniasis (CL). We selected 28 patients of both sexes, aged 60 years or older, diagnosed with CL and confirmed by detection of L. braziliensis DNA. The groups were treated with different total doses of medication: G1: 12 mg/kg; G2: 18mg/kg; G3: 24 mg/kg. Clinical and laboratory evaluations were carried out during the period of 180 days (D0, D15, D30, D60, D120, D150 and D180).
This project is composed of a phase I study with the purpose of evaluating adverse reactions and the best dose to be used of Sm29 and a phase II randomized controlled study with 3 arms with the purpose of comparing the efficacy of meglumine antimoniate associated with Sm29, with meglumine antimoniate plus placebo and meglumine antimoniate alone in the treatment of cutaneous leishmaniasis.
An effectiveness-implementation sequential explanatory hybrid design type 2 was performed in two rural communities of Colombia. A quasi-experimental study with historical control (standard of care) was designed to estimate the effectiveness of community-based intervention using the Guaral+ST mobile application (app). Three implementation outcomes were evaluated: acceptability and usability by qualitative methods, and fidelity by quantitative methods
Clinical, epidemiological, therapeutic and microbiological investigation of an outbreak of cutaneous Leishmaniasis that occurred among military personnel in French Guiana in 2020.
Infections due to protozoa of the genus Leishmania are a major worldwide skin problem, with high endemicity in developing countries including Pakistan. As far as concern for the treatment of cutaneous leishmaniasis (CL), there is no single therapeutic agent that has proved a satisfactory efficacy and safety. Therefore, the objective of this research study was to develop an alternative therapeutic approach for the treatment of CL. In the current research protocol, two herbal topical formulations (Gyburene and Thuscare) were prepared containing to contain 5% Casuarina equisetifolia L. and Thespesia populnea L. plant extract and evaluate their leishmanicidal potential in pre-clinical and randomized clinical trials studies. Preclinical studies were performed on BALB/c mice after the development of a lesion on the dermis caused by the Leishmania (L.) major parasite. Six weeks randomized, single single-blind placebo controlled study was also conducted on seventy eight L. major infected patients divided into three groups i.e. treated, reference and placebo with the 1:1 ratios.
Outcomes 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.
The 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 sand fly is visible but small and inconspicuous. There are different types of leishmaniasis which can 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 but many of them are not easy to use or don't work well. Therefore, new treatments are needed including vaccines 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 knowledge that has led to advances in the development of treatments. This is study builds on an our initial successful study, FLYBITE, where uninfected (disease-free) sand flies were used to test the safety aspects and ensure that sand flies were able to bite human participants in a controlled environment. The investigators observed no major adverse effects and it was well tolerated by participants. The investigators therefore wish to proceed to a study using sand flies infected with a form of leishmaniasis that causes localised skin disease and is treatable, on the pathway to assessing future vaccines.
This is a Phase 1, double-blind, randomized, placebo-controlled, first time in human (FTIH) study to assess the safety, tolerability and PK of a single dose of GSK3494245. The study will consist of 3 cohorts, conducted in a sequential manner. Cohorts 1 and 2 will consist of a single ascending dose (SAD), crossover design where each participant will receive a maximum of 3 ascending oral doses of GSK3494245 and 1 placebo dose under fasted conditions. At each dose level, GSK3494245 and placebo will be administered in a 3:1 ratio, within each period, according to the randomization schedule in a blinded manner. Cohort 3 will comprise of a 2-way crossover which includes 1 dosing regimen under fasted then fed conditions and 1 regimen under fed then fasted conditions in a 1:1 ratio. The fed conditions will investigate the effect of safety, tolerability and PK of a single dose of GSK3494245 following food administration.
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.
Anthroponotic Cutaneous Leishmaniasis (ACL) is a parasitic disease caused by Leishmania tropica, pentavalent antimonials (sodium stibogluconate and meglumine antimoniate) have been used as a standard treatment for leishmaniasis for last 80 years. Systemic antimonial injection is painful, toxic, not affordable and moreover is not always effective. Many different modalities are used to treat the disease with a limited success. Intra-lesional injections of antimonials are used for the treatment of patients with a few lesions but no data is available on the rate of efficacy. In this study the efficacy of intra-lesional injections of Glucantime weekly is compared with intra-lesional injections of Glucantime twice weekly.
