Brief summary

The aim of this study is, to investigate, whether the consumption of a probiotic yoghurt containing 4 probiotic strains naturally colonizing the vagina (L. crispatus, L. gasseri, L. rhamnosus, L. jensenii) has an influence on the comfort of adult women with BV after and 3 weeks following a standard antibiotic treatment with metronidazole.

Detailed description

Female volunteers aged ≥18 years with stable menstrual cycle or postmenopausal women presenting with a newly diagnosed bacterial vaginosis based on Amsel criteria, complying with a standard oral antibiotic treatment (Metronidazol (Arilin®) 7 days 2x500mg), willing to consume for 4 weeks the study product two times daily, complying with the dietary restrictions (s. a.) and complying with the other inclusion and exclusion criteria will be enrolled in the study. After enrollment subjects will be randomly and evenly assigned to one of the two test groups verum and placebo.The study population will be recruited in a screening examination (G1) by gynaecologists from Kiel area. This screening examination (routine examination) by gynaecologist is used to provide the diagnosis BV. After enrolment subjects will be randomly assigned to one of the two test groups verum (n=108) and placebo (n=108).

Interventions

verum is a liquid probiotic yoghurt containing all four probiotics as described in the arm description. Study participants consume daily two bottles (125g) during an intervention period of four weeks.

OTHERchemically acidified milk

Placebo is chemically acidified milk without bacterial strains. Study participants consume daily two bottles (125g) during an intervention period of four weeks (randomly assigned).

DRUGArilin

2 tablets Arilin 500mg for 7 days
