The Value of Bacterial Loads by Real Time PCR in Predicting Recurrence of Abnormal Vaginal Flora After Oral Metronidazole Therapy

January 12, 2017 updated by: Assistance Publique Hopitaux De Marseille
Abnormal vaginal flora is currently diagnosed among women (20-40%). It is associated with symptoms (bad smell, vaginal discharge) and adverse out-comes in pregnant and not pregnant women. The high recurrence rate raises the long-term effectiveness of therapy. The hypothesis is the persistence of bacteria associated with vaginal flora imbalance as Atopobium vaginae and Gardnerella vaginalis. At the present time there is a lack of an accurate marker for the risk of recurrence.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Women with symptomatic abnormal vaginal flora (a Nugent score of 4-10 or sup or egal 3 Amsel criteria) will be enrolled. Abnormal vaginal flora will be treated with 2g of oral metronidazole. Follow-up will be performed at 1 week,1 month and 12 months after treatment. Vaginal samples will be tested by quantitative real time PCR to determine the vaginal concentrations of A. vaginae, G. vaginalis, and Lactobacillus spp.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
To access the value of A. vaginae and G. vaginalis loads in predicting recurrence of abnormal vaginal flora over the course of 12 months after oral metronidazole therapy.
Time Frame: 2 YEARS
2 YEARS

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Inform the predictive and technical characteristics (sensibility and specificity) vaginal microbial concentrations
Time Frame: 2 YEARS
2 YEARS
