Filter by:Intralesional injection of antimony has been used for L major from Iran with a modest cure rate [56%: Asilian 2004]. However, this therapeutic approach has been used for L braziliensis from Brazil, with an attractive cure rate after 3 months of 80% [Oliveira-Neto 1997]. Because intralesional Sb injections is the local therapy with the best reported cure rate for South American L braziliensis disease, the species that causes disease in Bolivia, this pilot study of local therapy for bolivian L braziliensis disease will evaluate intralesional Sb therapy.
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.
Kala azar (KA) or visceral leishmaniasis (VL) is endemic in several districts of Bangladesh with the highest incidence in Mymensingh, Pabna and Tangail districts. ICDDR,B is involved in a project for improving the surveillance of KA in Trishal, Mymensingh since 2005. Improvement of case detection is necessary for both surveillance purposes and better control. The aims of this pilot study are to assess some newer techniques for diagnosis of KA using blood and urine samples of suspected cases; and evaluate response to treatment with sodium stibogluconate to which resistance has been reported in India, considered to be a part of the same zone harboring the disease agent Leishmania donovani and transmitted by the same vector Phlebotomas argentipes (sand-fly). No data is currently available on response to sodium stibogluconate in KA patients in Bangladesh. Although a number of new drugs have been evaluated in the treatment of KA in India and Kenya, no trial has so far been conducted in Bangladesh. A team of researchers from GlaxoSmithKline (UK) had recently visited Bangladesh to evaluate if it would be possible to conduct a Phase-III clinical trial with sitamaquine. They interacted with scientists of ICDDR,B and expressed their interest to help develop ICDDR,B's capacity in order to include Bangladesh as one of the sites for the planned, multi-centre, Phase-III trial of sitamaquine; India and Nepal are two other possible sites for the trial. The aims of the proposed study are to train physicians and laboratory personnel in preparation for the future drug trial(s) on KA as well as to compare different tests for its diagnosis that might improve case detection at the field level and used for research purposes. The investigators will also examine in greater detail the different Leishmania species circulating in the area of Mymensingh and whether treatment failure and occurrence of Post Kala azar Dermal Leishmaniasis (PKDL) is associated with certain species.
The objectives of the study are to evaluate the safety, pharmacokinetics (PK), and efficacy of open label treatment with WR 279,396 (Topical Paromomycin/Gentamicin Cream)in subjects with cutaneous leishmaniasis (CL).
This study is designed to evaluate the immune and therapeutic responses of visceral leishmaniasis patients using N-acetylcysteine (NAC) as an adjuvant therapy to pentavalent antimony.
This protocol will evaluate the efficacy and safety of various combinations of the three drugs; AmBisome, Paromomycin and Miltefosine at reduced total dosage against the standard treatment with a total dose of 15mg/kg of AmBisome.
The objectives of the study are to evaluate the pharmacokinetics (PK), safety, and efficacy of WR 279,396 (Paromomycin + Gentamicin Topical Cream) and Paromomycin Topical Cream in subjects with cutaneous leishmaniasis (CL).
Visceral leishmaniasis (VL) / Kala-azar (KA) is a public health problem in the many countries in the world including Bangladesh. Where more than 90,000 VL cases have been reported since 1994. The disease is fatal if not treated. Even with treatment the mortality rate is high (10%). VL is a vector-borne disease, caused by the parasite Leishmania donovani (LD) and is transmitted by female sandfly sp. Phlebotomus argentipes. Not all people exposed to the LD parasite develop disease. According to our observation only about 30% of the infected with LD parasite develop disease within one year of diagnosis. Malnutrition and intestinal helminth infection have been found to be associated with the risk of active VL. Down regulation of Th1 cellular immune response confers susceptibility to active VL. Both malnutrition and intestinal helminth infection down regulate the Th1 cellular immune response. Till now there is no established prophylaxis against active VL among the people exposed to the LD infection. Many studies including ours have been shown that periodic regular deworming reduced malnutrition significantly. Micronutrient such as zinc and iron as well vitamin A supplementation also improve malnutrition and may enhance Th1 cellular immune response. Thus we hypothesize that periodic deworming and. micronutrient and vitamin A supplementation together may reduce the risk of active VL among the people exposed to the LD infection. The study will be carried out in the Harirampur union, Trishal, Mymensingh. This area is highly endemic for VL. Two hundred asymptomatic VL patients aged 2-60 will be enrolled to the study. Children aged less than 2 years, pregnant women, active VL case, person with chronic disease, disable individuals and those who will refuse written consent will not be enrolled to the study. After enrollment subjects will be divided into two groups through randomization. One group will receive deworming and nutritional supplement (intervention group) and other group will receive placebo (placebo group). Two groups will be followed for 12 months through active surveillance for developing of active VL. In addition morbidity data, monthly stool sampling, monthly anthropometry, urine and blood sampling at baseline, before and after treatment of active VL will be carried out Successful completion of the study and derived results from it will provide useful information that whether periodic deworming with micronutrient and vitamin A supplementation can reduce the risk of active VL among the people exposed to the LD infection.
This study is to assess if shorter combinations of SSG plus single dose AmBisome®, Miltefosine plus single dose AmBisome® and Miltefosine alone are effective in treating visceral leishmaniasis in Eastern Africa.
The purpose of this Treatment Investigational New Drug application was to make miltefosine available for mucocutaneous leishmaniasis patients presenting in the United States. If entrance criteria were met, subjects with mucosal or cutaneous leishmaniasis received miltefosine at a targeted dose of 2.5 mg/kg/day for 28 days. During treatment at weeks 1, 2, and 4, the patient returned to the treatment facility to be assessed for adverse events. Blood for transaminase and creatinine values were drawn at the midpoint and at the end of therapy. Patients returned to the treatment facility to be examined clinically at 6 weeks (ie, 2 weeks after the end of therapy), 3 months (2 months after therapy), and 7 months (6 months after treatment) for mucosal leishmaniasis and cutaneous leishmaniasis patients, and also at 13 months (12 months after treatment) for mucosal leishmaniasis patients.
