During L. donovani infection in golden hamsters, tremendous hepatic damage was observed as apparent from increased activities of glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, succinate dehydrogenase, glucose-6-phosphatase and acid ribonuclease. The levels of cytochrome P-450 and related monooxygenases, viz. aniline hydroxylase and aminopyrine-N-demethylase registered significant decrease in infected animals. Sodium stibogluconate, a standard antileishmanial drug, though caused the removal of parasites from infected tissues, but did not help in the recovery of deranged hepatic markers. The results explain the higher mortality of stibanate treated infected animals as compared to untreated animals infected with L. donovani.

The pentavalent antimonial compounds Glucantime and Pentostam are the first line drugs used in anti-Leishmania treatment. However, no in vivo studies have compared the efficacy and toxicity of these drugs where host variability has been controlled. Biochemical studies of Leishmania have detected differences between the two drugs with regard to DNA topoisomerase I inhibition, a phenomenon that possibly impacts treatment efficacy. To evaluate the clinical efficacy, hamsters were infected intradermally in the right hind foot with 10(6) promastigotes of a wild type or luciferase-transfected Leishmania panamensis. At three weeks post-inoculation, the animals were treated intramuscularly with either Glucantime or Pentostam (30, 60 or 120 mg SbV/kg per day for 20 days). To evaluate parasitological efficacy a luminometry assay was standardized for quantitation of amastigotes in hamster tissues. To evaluate toxicity, hamsters were treated intramuscularly with Glucantime or Pentostam (120, 160 or 240 mg SbV/kg per day for 20 days). Animals inoculated with either of the parasite strains and treated with either drug, showed a similar rate of lesion reduction, as compared to untreated controls (p<0.01). Parasite burden was also comparable, and no significant differences were found in the cure rate. No renal or hepatic alterations occurred as evidenced by normal serum levels of creatinine, aspartate aminotransferase, alanine aminotransferase and amylase. Hamsters treated with 120 mg SbV/kg per day for 20 days or higher doses of Pentostam showed macro- and microscopic signs of inflammation at the site of injection. These effects were absent in the animals treated with Glucantime. The results confirmed clinical observations regarding the similar efficacy of the two drugs, as well as the higher local toxicity of Pentostam.
