BACKGROUND Leishmaniasis is a common parasitic disease in Southern Europe, caused by Leishmania infantum. The failures of current treatment with pentavalent antimonials are partially attributable to the emergence of antimony-resistant Leishmania strains. This study analyses the in vitro susceptibility to pentavalent antimony of intracellular amastigotes from a range of L. infantum strains, deri...
American tegumentary leishmaniasis is an infectious disease caused by a protozoan of the genus Leishmania. Pentavalent antimonials are the first choice drugs for cutaneous leishmaniasis (CL), although doses are controversial. In a clinical trial for CL we investigated the occurrence of pancreatic toxicity with different schedules of treatment with meglumine antimoniate (MA). Seventy-two patient...
The mechanisms linking the immune response to cutaneous and mucosal leishmaniasis (CL and ML, respectively) lesions and the response to treatment are incompletely understood. Our aims were to prospectively assess, by quantitative reverse transcription-PCR, the levels of mRNA for gamma interferon, tumor necrosis factor alpha, interleukin-10 (IL-10), IL-4, and IL-13, as well as the presence of T ...
introduction: the treatment of cutaneous leishmaniasis (cl) is based primarily on the use of pentavalent antimonials, which may lead to many side effects limiting their use. photodynamic therapy (pdt) is an alternative for the treatment of cl, and some xanthene dyes have the potential for use in pdt. methods: the xanthenes rose bengal b (rb) and its derivatives rose bengal methyl ester (rbmet),...
Leishmaniasis is a neglected public health problem caused by the protozoan species belonging to the genus Leishmania affecting mostly the poor populations of developing countries. The causative organism is transmitted by female sandflies. Cutaneous, mucocutaneous, and visceral clinical manifestations are the most frequent forms of leishmaniasis. Chemotherapy still relies on the use of pentavale...
The pentavalent antimonial (Sb5+) meglumine is the drug of choice for the treatment of cutaneous leishmaniasis (CL) in Brazil. Although the cardiotoxicity of high-dose, long-term Sb5+ therapy is well known, the use of low-dose, short-term meglumine has been considered to be safe and relatively free from significant cardiac effects. In order to investigate the cardiotoxicity of low-dose, short-t...
Treatment of cutaneous leishmaniasis is often difficult. Even though most cutaneous lesions will heal spontaneously, their duration cannot be predicted in an individual case. In general, only large, multiple or diffuse lesions of the face, head and neck need to be considered for therapeutic intervention. Pentavalent antimonials (sodium stibogluconate and meglumine antimoniate) administered intr...
In many tropical areas, infections by Leishmania species are endemic and include visceral leishmaniasis (VL), which is often fatal if untreated. Outside India, VL treatment and control are based on long-term administration of highly toxic pentavalent antimonials. Previously, we described the synthesis and in vitro leishmanicidal activity of a series of nine benzophenone derivatives with low tox...
