Study Description
Brief Summary:
Abnormal vaginal flora is a risk factor for preterm labor. Therefore, in high risk pregnancies for preterm labor the diagnosis and treatment of abnormal flora is indicated. Clindamycin and metronidazole given orally are both acceptable treatments in these cases. The purpose of this study is to compare the effectiveness of Clindamycin Vs metronidazole for the treatment of abnormal vaginal flora in high risk pregnancies. For this purpose, pregnant women who are considered high risk for preterm labor and were diagnosed with abnormal vaginal flora will be randomly treated either with clindamycin or metronidazole. Eradication of the abnormal flora and adverse effects will be monitored and compared

Official Title: Comparison Between Oral Clindamycin Vs Metronidazole for the Treatment of Abnormal Vaginal Flora in High Risk Pregnancies
Study Start Date : April 2012
Estimated Primary Completion Date : March 2018
Estimated Study Completion Date : March 2018


Arms and Interventions

Arm Intervention/treatment
Experimental: clindamycin Drug: Clindamycin
Oral clindamycin 300 Milligrams*2/Day for a week
Experimental: metronidazole Drug: Metronidazole
Oral metronidazole 500 Milligrams*2/Day for a week


Outcome Measures

Primary Outcome Measures :
  1. To compare the efficacy between oral Clindamycin Vs Metronidazole in the eradication of abnormal vaginal flora [ Time Frame: Primary outcome will be assessed by taking a vaginal culture sample a week after one-week antibacterial treatment ]

Secondary Outcome Measures :
  1. The prevalence of adverse effects [ Time Frame: During the antibacterial treatment which is 1 week of therapy ]
  2. The prevalence of late abortions and preterm deliveries [ Time Frame: From date of randomization until the date of delivery or abortion, assessed up to 28 weeks ]
  3. Assessing the correlation between Nugent score , physical examination and Ph indicators [ Time Frame: The outcome is assessed after the diagnosis of abnormal vaginal flora is made at 14-26 weeks of gestation ]
