Standard therapy of human visceral leishmaniasis with parenteral pentavalent antimonial agents is generally curative but has the disadvantages of a 28-day treatment course, occasional treatment failures, and toxicity. The antifungal and antileishmanial agent amphotericin B has been complexed with lipids to develop a less toxic formulation of amphotericin B. Because lipid particles are phagocyti...

The Indian subcontinent is the only region where arsenic contamination of drinking water coexists with widespread resistance to antimonial drugs that are used to treat the parasitic disease visceral leishmaniasis. We have previously proposed that selection for parasite resistance within visceral leishmaniasis patients who have been exposed to trivalent arsenic results in cross-resistance to the...

We report the case of a 33-year-old man referred to our department with a skin ulcer that had appeared 1 year earlier on the left posterior axillary fold. His medical history was remarkable for chronic hepatitis B infection being treated with adefovir and for psoriatic arthritis, under treatment with leflunomide 20 mg/d, prednisone 5 mg/d, and infliximab 5 mg/kg every 8 weeks for the past 2 yea...

Metabolic syndrome, diabetes and diabetes complications pose a growing medical challenge worldwide, accentuating the need of safe and effective strategies for their clinical management. Here we present preclinical evidence that the sorbitol derivative meglumine (N-methyl-D-glucamine) can safely protect against several features of metabolic syndrome and diabetes, as well as elicit enhancement in...

Background: Several treatment modalities have been used for cutaneous leishmaniasis (CL) with various results. In vitro and in vivo studies have shown inhibitory effects of zinc sulfate (ZnSO4) on Leishmania parasites. Objective: To compare the efficacy of intralesional injections of 2% ZnSO4 solution with meglumine antimonate (Glucantime) in the treatment of acute Old World CL. Patients ...

Cholografin Meglumine (lodipamide Meglumine Injection 52%) is a radiopaque contrast agent for rapid intravenous cholangiography and cholecystography supplied as a sterile, aqueous solution. Each mL provides 520 mg iodipamide meglumine; at manufacture, 3.2 mg sodium citrate buffer and 0.4 mg edetate disodium sequestering agent are added per mL. The pH has been adjusted between 6.5 and 7.7 with m...

The purpose of this study was to investigate comparison between oral zinc sulfate and meglumine antimoniate in the treatment of cutaneous leishmaniasis (CL). So 100 patients with CL were included and randomly divided into two groups. The first group was treated with oral zinc sulfate (10 mg/kg/day during 45 days period), and the second group was treated with systemic meglumine antimoniate (20 m...

For localization of pyroantimonate-precipitable cations, mouse testes were fixed with a saturated aqueous solution of potassium pyroantimonate (pH about 9.2, without addition of any conventional fixative), hardened with formaldehyde, and postosmicated. A good preservation of the cell membranes and over-all cell morphology is obtained as well as a consistent and reproducible localization of the ...

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...

Two titanium antimonate materials were tested for the removal of radiocobalt from a solution containing complexing agent EDTA to simulate a nuclear power plant decontamination solution. The first material had a mixture of pyrochlore and rutile structures and it showed high removal (91 %) of radiocobalt was removed in the presence of EDTA. The second material, which had a mopungite structure, sh...
