Treatment of Bacterial Vaginosis Prior to Active Labor and Infectious Morbidity

Phase 1
Terminated
Conditions
Bacterial Vaginoses
Interventions
Drug: Placebo Oral Tablet
Registration Number
NCT03954990
Lead Sponsor
The University of Texas Medical Branch, Galveston
Brief Summary

Bacterial vaginosis (BV) is the most common cause of vaginal discharge among repro-ductive aged women. It is been linked to adverse maternal and neonatal outcomes. Our objective is to evaluate if the use of a single dose of metronidazole in women with BV at time of delivery reduces infectious morbidities

Detailed Description

The investigators are proposing a double-blinded, placebo controlled, randomized trial of 525 pregnant women undergoing induction or admitted in early labor and who are diagnosed with bacterial vaginosis. On admission to labor and delivery, patient will be counseled about the study. Patients who agree to be enrolled, will sign informed consent. Following enrollment patients will be screened for Bacterial vaginosis by doing a speculum exam and testing for Amsel's criteria. BV +ve patients will be randomized to receive either metronidazole 2 grams PO once or identically appearing placebo. The PI, study coordinator, or a collaborator will be responsible for the informed consent.

This will be a double-blinded randomized clinical trial. Neither the patient nor provider will be aware of treatment assignment. As with any other in-stance in which antibiotics are administered, there is a chance of an allergic or other adverse reaction. The patient will receive standard inpatient monitoring during the labor course and in the postpartum period, and so any immediate adverse reaction would be promptly detected.

Patient will be assessed intrapartum for development of chorioamninoitis. Postpartum patient will be assessed for infective complications up to 4 weeks. Neonates will be assessed for morbidities by chart review for 90 days.
