Single dose of tinidazole in the treatment of vaginal discharge.
Seventy-nine unselected women whose main symptom was abnormal vaginal discharge were seen at the Department of Obstetrics and Gynecology at Helsinki University Central Hospital between October 1980 and September 1981. All patients and their current sex partners were randomly treated either with a 2-gram single dose of tinidazole or with identical placebos. Those excluded were 9 patients who did not attend the follow-up examination, 15 who had specific cervicovaginal infections (6 with chlamydial infection, 4 with trichomoniasis and 5 with yeast infection), and 22 with normal Döderlein flora seen on vaginal Pap smear. Response to the treatment was analysed among the remaining 33 women, of whom 17 received tinidazole and 16 placebo. The symptoms and signs that best discriminated between those who had normal Döderlein flora and those who had non-Döderlein flora were malodour, other than white colour of the discharge, and the presence of clue cells on Pap smear. When these findings were used to evaluate the response to treatment, tinidazole proved to be more effective than placebo. Disappearance of clue cells best (p less than 0.01) discriminated between tinidazole and placebo.
