  Purpose

Bacterial vaginosis (BV), the world's most common vaginal infection, continues to cost patients time, energy, comfort and money. BV is associated with increased incidence of sexually transmitted infections (including HIV), spontaneous abortion, pre-term labour, post-surgical infections, and endometritis. Current treatment for those women symptomatic for BV includes both oral and intravaginal antibiotics, such as metronidazole, which have success rates of 70-80 % at 1 month after treatment. These treatments also have high recurrence rates (49-66 % at one year after treatment) and side effects (10-20 % of women) that include secondary vaginal infection with candida. Intravaginal boric acid has been used for >100 years for the treatment of vaginal infections and is quite commonly prescribed today as a treatment for BV. It is cheap, easily accessible, easy to use, and is an effective treatment of other vaginal infections, such as candida. To date, there are no clinical trials studying the effectiveness of boric acid in the treatment of BV.

Objectives: To determine whether boric acid is at least as effective and as safe as metronidazole for treating women with symptomatic BV, our study will compare intravaginal boric acid to the current standard intravaginal treatment, metronidazole, and to a placebo. Our goal is to expand women's options for the treatment of BV. Hypothesis: Boric acid is an effective treatment of bacterial vaginosis as compared to placebo. Boric acid is at least as effective and as safe in the treatment of bacterial vaginosis as compared to metronidazole.

Further study details as provided by University of British Columbia:

Primary Outcome Measures:
  • Effectiveness of treatment of intravaginal boric acid and metronidazole at 1 week and 30 days post-treatment will be measured as absence of symptoms or negative vaginal swab (Nugent score less than 7) if symptoms are present for BV. [ Time Frame: 1 month ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • If during the 10 days of treatment of intravaginal boric acid and metronidazole the patient discontinues the treatment because of side effects or complained of intolerable side effects this will be considered a treatment failure for safety. [ Time Frame: 1 month ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria:

Women will be included whether their complaint is symptoms of BV and have a positive whiff test/vaginal swab or if they have a positive whiff test/vaginal swab and are then asked if they have any symptoms of BV present. The following criteria must be met for enrolment in the study:

  2. capable of giving written informed consent;
  3. English speaking;
  4. negative pregnancy test on enrolment day;
  5. agree to follow study protocol;
  6. documented BV infection by positive vaginal swab +/- positive whiff test/pH > 4.5;
  7. agree to no intercourse for the 10 days of treatment (or to use non-lubricated condoms if unavoidable);
  8. agree not to douche or use any intravaginal products during treatment (including tampons, medications, devices);
  9. abstain from alcohol during the 10 days of treatment (from 24 hours before through 72 hours after taking study medication);
  10. agree to no new medications or antibiotics during treatment;
  11. no current sexually transmitted infection as determined by history, physical exam and negative swabs for chlamydia, gonorrhea, candidiasis, trichomonas;
  12. patient is reliable for follow up.

Exclusion Criteria:

The following women would be excluded from study participation:

  1. less than 16 or post-menopausal;
  2. negative vaginal swab regardless of whiff test/pH > 4.5;
  3. menstruating at diagnosis;
  4. symptoms so severe as to make allocation to placebo unacceptable to the patient;
  5. currently pregnant or at high risk for pregnancy;
  6. current sexually transmitted infection (HIV, hepatitis, chlamydia, gonorrhea, trichomonas, HPV or HSV);
  7. current yeast infection as determined by history, physical and swabs;
  8. history of PID;
  9. allergy to latex or metronidazole;
  10. presently lactating;
  11. any open wound, excoriation, vaginal irritation and including bartholin's cyst/abscess as determined by physical exam;
  12. presence of another vulvar, vaginal or medical condition, including cervical neoplasia treatment, that might confound treatment response;
  13. using lithium, anti-coagulants or disulfiram drugs;
  14. any antifungal or antibiotic use 14 days prior to enrolment
  15. PAP smear done within one week of enrollment.
