Fifty-nine women with trichomonal vaginitis were randomly allocated to receive treatment with a single oral dose of either 0.5, 1.0, or 1.5 g of ornidazole. One week after treatment, a parasitologic cure was observed in 100% of patients treated with 1.5 g, in 95% of patients treated with 1.0 g, and in 65% of patients given 0.5 g. At the one-month follow-up visit, the cure rate remained at 100% for the 1.5-g dose group but dropped to 85 and 45% in the 1.0- and 0.5-g dose groups, respectively. The disappearance of symptomatic complaints was also dose related: the clinical cure was 100, 85, and 40% at the first follow-up visit and 89, 80, and 30% at the second follow-up visit. Adverse effects of mild or moderate severity were reported by 13 patients. These were encountered mostly in the 1.5- and the 1.0-g dose groups. The most frequent adverse effects were dizziness and gastrointestinal distress. Laboratory safety test did not reveal any significant toxicity. This study confirms that single-dose treatment of trichomoniasis with an oral dose of 1.5 or 1.0 g of ornidazole is effective and well tolerated.

Go.10213, a new nitroimidazole, was studied in 12 male volunteers for tolerability and in 20 patients with intestinal amoebiasis for antiamoebic activity. Go.10213 was well-tolerated by volunteers up to a dose of 400 mg X 3. Patients also tolerated well the dose of 100-150 mg X 3 for 7 days. In two patients, there were mild and transient side-effects like headache, dizziness, fatigue, etc. No neurological side-effects were observed. There were no significant changes in blood pressure, pulse rate and ECG. The organ function tests did not show any adverse effects of Go.10213 on bone-marrow, kidney, liver, etc. Go.10213, at a dose of 150 mg X 3, showed potent antiamoebic activity in 10 patients with intestinal amoebiasis, as judged by the clinical relief, the eradication of the trophozoites and cysts of Entamoeba histolytica from stools and the healing of colonic ulcers. Go.10213, a novel nitroimidazole, may prove to be the most potent and safe agent against the protozoal infections, e.g. amoebiasis, giardiasis and trichomoniasis.

Trichomonas vaginalis is an important human parasite of the urogenital tract. Jasmonates are a group of small lipids that are produced in plants and function as stress hormones. Naturally occurring methyl jasmonate (MJ) has been used to treat several types of cancer cells and it is cytotoxic to protistan parasites. It has been suggested that mitochondria are the target organelles of jasmonates. Here, we tested this drug against T. vaginalis. Although metronidazole has been the drug of choice for trichomoniasis, side effects from this treatment are common, and nausea and dizziness have been reported in up to 12% of patients. In addition, there has been increased recognition of resistance to metronidazole. We demonstrate here using flow cytometry, JC-1 and scanning and transmission electron microscopy that MJ induced the cell death of T. vaginalis parasites. Our results are discussed with previous findings published by others.
