Filter by:A cluster-randomized vector control trial in Bihar, India, and neighboring Nepal, will test the efficacy of long-lasting impregnated bednets (LLINs, Permanets) for reducing visceral leishmaniasis incidence. The intervention unit is the village (400-1000 people). The study is designed to detect a 50% reduction in Leishmania donovani incidence in intervention compared to control clusters over 2 years. 24 clusters (selected as high incidence during previous years) will be randomly allocated to intervention or control. Following health education, and with informed consent, all households in intervention villages will receive free Permanets (from September 2006). Net usage will be monitored and new nets provided if required. Control villages will not be given untreated nets, as - although commonly used in this region - their effectiveness against sandflies has not been proven. Pre-intervention infection status of villagers (>2 yrs) will be evaluated serologically from finger-prick blood (and past/current disease status noted). Incident infections will be recorded by 3-monthly active search for clinical cases, and by annual serological diagnoses to detect subclinical infections. All villagers (>2yrs) will be leishmanin skin tested at the end of the trial for further subclinical infection detection, and sera from a sub-sample will be tested for antibodies to sandfly saliva antigens (a measure of sandfly exposure). All clinical cases will be given free treatment. Free Permanets will be provided to control villages after the trial. Complementary studies involve entomological surveillance by light traps in a sample of houses and social/economic questionnaire surveys. The entomological surveys will test whether community-wide use of LLINs provides any mass effect, which could protect those in the community who fail to use LLIN for any reason.
The purpose of this study is to determine whether low-dose pentavalent antimony is equally effective when compared to the standard-dose regimen in patients with cutaneous leishmaniasis. The study will be done in a field clinic in the state of Bahia, Brazil.
This study is being conducted to assess the safety and efficacy of amphotericin B deoxycholate in doses of 0.75 mg/kg or 1.0 mg/kg for 15 doses. In each arm the drug is given in the conventional way every alternate day against the daily administration regimen being tested.
This study will test whether addition of imiquimod to standard antimony therapy provides a significant benefit in subjects with newly diagnosed cutaneous leishmaniasis. Based on our previous results, we hypothesize that lesions in patients who receive the combined treatment of pentavalent antimony and imiquimod as a first line therapy will resolve more rapidly and produce less scarring than treatment with pentavalent antimony alone.
The purpose of this study is to assess the efficacy and safety of SSG 30 days alone, PM 21 days alone and SSG and PM as a combination course of 17 days in the treatment of patients with VL.
Cutaneous leishmaniasis is typically treated with the parenteral product pentavalent antimony. Miltefosine is an oral agent shown to be active for mucosal leishmaniasis due to L braziliensis in Bolivia and cutaneous leishmaniasis due to L panamensis in Colombia. This trial is intended to evaluate miltefosine for cutaneous leishmaniasis due to L braziliensis in Bolivia. Patients will be randomly assigned to miltefosine or pentavalent antimony. Standard dose regimens will be used for both drugs.
Symptomatic Visceral Leishmaniasis(VL)is fatal; Due to the increasing resistance to standard therapy with antimonials, there is a need for new safe, efficacious, low-cost therapies for the treatment of VL. Paromomycin is an off-patent aminoglycoside antibiotic with anti-leishmaniasis activity. This study will test the safety and efficacy of paromomycin in the treatment of patients with VL in India.
This study will evaluate the safety and immunogenicity of the Leish-111f + MPL-SE vaccine in adult subjects who have no evidence of previous exposure to the Leishmania parasite.
This study will evaluate the safety of the Leish-111f + MPL-SE vaccine in adult subjects with a previous exposure to the Leishmania parasite (but without current or past history of leishmaniasis).
This study will evaluate the safety of the Leish-111f + MPL-SE vaccine in adult patients with cutaneous leishmaniasis.
