Disseminated leishmaniasis (DL) is an emerging and severe form of leishmaniasis, with increasing prevalence in Bahia, Brasil. It is characterized by multiple acneiform, papular and ulcerated lesions localized on the face, chest, abdomen and extremities. The number of lesions ranges from 10 to hundreds, and mucosal disease has been documented in more than 40% of the cases. DL is a hard to cure disease and therapeutic failure with pentavalent antimony has been documented in up to 70% of the cases caused by L. braziliensis in the endemic area of Corte de Pedra, Bahia. The majority of DL patients need several courses of antimony or the use of high dose of Amphotericin B desoxicolate to cure. Therefore DL patients are exposed to relevant drug toxicity, high morbidity due to a long lasting disease, with an important socio-economic impact. Our hypothesis is that liposomal Amphotericin B has a higher cure rate than historic cure rates of pentavalent antimony in the treatment of disseminated leishmaniasis.
The overall objective of this trial is to identify a safe and effective treatment for visceral leishmaniasis (VL) in HIV co-infected Ethiopian patients. Patients will receive either Ambisome alone or Ambisome in combination with Miltefosine. Patients who do not undergo treatment failure will be given a VL prophylactic treatment with Pentamidine one month after the end of the study treatment.
The objectives of the study are to evaluate the safety and efficacy of open label treatment with WR 279,396 (topical paromomycin & gentamicin) in patients with non-complicated, non-severe cutaneous leishmaniasis (CL).
We hypothesize that PKDL develop after SSG as well as after Miltefosine mono-therapy for VL; anti-inflammatory cytokines such as IL-10, TGF-β, serum lipids play key role for its pathogenesis & PKDL patients are genetically predisposed; diagnostic tool based on immunofluorescence technique will be more sensitive than slit skin examination for diagnosis of PKDL.
The aim of this work was to investigate the healthcare professionals' knowledge about leishmaniasis in Divinópolis, an endemic county of Minas Gerais state, Brazil.
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.
The proposed study encompasses a two-step approach. The first aiming to determine the safety of Topical 3% Amphotericin B Cream when applied three or two times per day for 4 weeks in subjects with un-complicated Cutaneous leishmaniasis (CL) whilst the second focusing in having and indication of the efficacy of the two above mentioned regimens of Topical 3% Amphotericin B Cream For the first step, 30 subjects will be randomly assigned to receive direct observed treatment (DOT) with Topical 3% Amphotericin B Cream applied either three or two times per day for 4 weeks. Enrolment will be temporarily halted until all 30 subjects (15 in each group) have been enrolled and completed the 28 day treatment course. An interim analysis of all safety (Adverse Events, including local reactions and lab parameters) and pharmacokinetics collected on subjects who were randomized will be performed by data safety monitoring board. If no serious adverse events (SAEs) related to the study drug are identified on the first 30 subjects by the end of the treatment course, 50 additional subjects will be randomly allocated to receive Topical 3% Amphotericin B Cream either three or two times per day for 28 days Subjects will have a follow-up visit at the end of therapy, on Day 45± 5 days, Day 63± 5 days and on Days 90± 14 days and on Day 180, minus 14d, plus 4 weeks to assess efficacy, as measured by the number of subjects who fulfil the cure criteria: 100% re-epithelialization of the lesion(s) by Day 90 and no relapse by Day 180. All subjects will be followed up to Day 180 for final analysis of efficacy.
This study is a pivotal Phase 3, randomized, double-blind, 3-site, two-group trial assessing the efficacy and safety of WR 279,396 Topical Cream and Paromomycin Alone Topical Cream in subjects with CL in Panama. The primary objective of this study is to determine if WR 279,396 results in statistically superior final clinical cure rates of an index lesion when compared with Paromomycin Alone for the treatment of CL in Panama expected to be caused by L panamensis.
The purpose of the study is to evaluate the sensitivity and specificity of CL Detect, in subjects with suspected CL in Tunisia.
