Résumé
Bacterial vaginosis [BV] is the most prevalent causes of abnormal secretion in women at fertility age. Also, Bacterial vaginosis is one of the most common diseases in women who refer to gynecology clinic. The main cause of the pathogenesis is increasing pH of vagina due to reduced number of lactobacillus and growth of anaerobic bacteria. Prevalence of BV varies between 10 to 30 percent in different societies. Amsel criteria is used as diagnostic test in BV. This interventional study was designed to assess the impact of vaginal lactobacillus suppository and metronidazole compared to metronidazole alone on the recovery and recurrence of bacterial vaginosis. This study was a prospective, randomized, double-blind clinical trial which was conducted on 130 women with bacterial vaginosis to compare the effects of vaginal lactobacillus suppository and metronidazole. Bacterial vaginosis was diagnosed using Amsel criteria that based on some clinical symptoms. Patients were divided into two groups, first group were treated with oral metronidazole plus lactobacillus and second group were treated with metronidazole alone. Patients were followed-up one week and four weeks after initiation of the treatment. One hundred and thirty women completed the study. Patients were followed at one and four weeks after initiation of intervention. Amsel criteria and recovery rate in both groups compared before treatment one and four weeks after treatment. The criteria and treatment were significantly improved, but this improvement was higher and statistically significant in the metronidazole plus Lactobacillus group compared to second group [P< 0.0001]. The protective effects of lactobacillus in dealing with anaerobic pathogens as well as the negative impact of metronidazole on lactobacillus of vaginal flora, use of lactobacillus along with metronidazole especially in patients with recurrent infections is recommended. In other words, using lactobacillus with metronidazole for treatment of bacterial vaginosis is more effective than metronidazole alone
