What researchers measure

Primary outcomes

  1. Microbiota

    Change from baseline in the composition of the vaginal microbiota with the increase of the cell density of lactobacilli (at least 3 log units) and decrease of pathogens (at least 2 log units) at the end of the treatment (10 days) and during the wash-out period (4 weeks after the end of the treatment)

    Time frame: Baseline; end of the treatment (10 days) ; wash-out (4 weeks)

  2. Signs

    Change from baseline of Amsel's criteria at the end of the treatment (10 days) and during the wash-out period (4 weeks after the end of the treatment)

    Time frame: Baseline; end of the treatment (10 days) ; wash-out (4 weeks)

  3. Signs

    Change from baseline of the Nugent score with values between 0 and 3 at the end of the treatment (10 days) and during the wash-out period (4 weeks after the end of the treatment)

    Time frame: Baseline; end of the treatment (10 days) ; wash-out (4 weeks)

  4. Symptomatology

    Change from baseline of vulvovaginal erythema/edema, vulvar discomfort, burning, and itching

    Time frame: Baseline; end of the treatment (10 days) ; wash-out (4 weeks)

Secondary outcomes

  1. Wellbeing

    Change from baseline of the quality of life based on the Short Form-36 (SF-36) questionnaire. Values ranging from 0 to 100 indicate worst and better outcomes, respectively.

    Time frame: Baseline; end of the treatment (10 days) ; wash-out (4 weeks)
