About this study
Official title: Prospective Evaluation of the Impact of Bacterial Vaginosis and Its Treatment on Mucosal Susceptibility to HIV-1 Infection and Endpoints of Cervico-Vaginal Safety
This is a research study to determine whether bacterial vaginosis (BV) changes the cervico-vaginal tissue (skin covering the cervix and vagina) and makes women at higher risk for getting HIV (Human Immunodeficiency Virus). Vaginal and cervical tissue biopsies from women with BV will be obtained and infected OUTSIDE the body (ex vivo) with HIV.
BV is a vaginal infection that develops when there is an imbalance in the normal bacteria found in a woman's vagina. It is the most common cause of vaginal discharge among women of child-bearing age. BV infections potentially harm the safety of the tissue surrounding the cervico-vaginal region. When the cervico-vaginal tissue is not well protected, the risk of acquiring HIV from an infected partner might increase significantly. Studies have shown that HIV is more common in women with BV than in women with normal vaginal bacteria.
Read more
Treatment of BV typically involves the use of antibiotics. Antibiotics kill harmful bacteria and provide a temporary relief from the symptoms caused by the infection. Women participating in this study will use the generic antibiotic metronidazole, also known as Flagyl. The Center for Disease Control and Prevention (CDC) recommends Flagyl for the treatment of BV.
The study will evaluate HIV infection and safety of cervico-vaginal tissue in women at 3 different time periods:
- During a BV infection
- Approximately 1 week after completing a 7-day course of metronidazole therapy
- Approximately 1 month after completing the 7-day course of metronidazole therapy
You will not come in contact with HIV during this study - only your samples (after we have removed them from your vagina/cervix) come in contact with HIV.
Read the detailed description
WHY ARE YOU BEING ASKED TO TAKE PART?

What is being measured
The primary outcome is the main question the study is designed to answer.
p24 Antigen Production in Tissue
The study will evaluate HIV infection and safety of cervico-vaginal tissue in women at 3 different time periods:
- During a BV infection
- Approximately 1 week after completing a 7-day course of metronidazole therapy
- Approximately 1 month after completing the 7-day course of metronidazole therapy
Each of the 33 participants were sampled at baseline (during BV infection), approximately 1 week after treatment and approximately 1 month after treatment. p 24 antigen data was not evaluable in this study due to the fact that the samples were frozen prior to laboratory analyses, which damaged the samples. No data were collected.
Measured: 6 weeks
p24 Antigen Production at Baseline Versus After Treatment With Metronidazole
p 24 antigen data was not evaluable in this study due to the fact that the samples were frozen prior to laboratory analyses.
Measured: 30 days

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a research study to determine whether bacterial vaginosis (BV) changes the cervico-vaginal tissue (skin covering the cervix and vagina) and makes women at higher risk for getting HIV (Human Immunodeficiency Virus). Vaginal and cervical tissue biopsies from women with BV will be obtained and infected OUTSIDE the body (ex vivo) with HIV.
BV is a vaginal infection that develops when there is an imbalance in the normal bacteria found in a woman's vagina. It is the most common cause of vaginal discharge among women of child-bearing age. BV infections potentially harm the safety of the tissue surrounding the cervico-vaginal region. When the cervico-vaginal tissue is not well protected, the risk of acquiring HIV from an infected partner might increase significantly. Studies have shown that HIV is more common in women with BV than in women with normal vaginal bacteria.
Treatment of BV typically involves the use of antibiotics. Antibiotics kill harmful bacteria and provide a temporary relief from the symptoms caused by the infection. Women participating in this study will use the generic antibiotic metronidazole, also known as Flagyl. The Center for Disease Control and Prevention (CDC) recommends Flagyl for the treatment of BV.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 26 Aug 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
