[Microbiota in women; clinical applications of probiotics].
The main function of vaginal microbiota is to protect the mucosa against the colonization and growth of pathogenic microorganisms. This microbiota is modified by hormonal activity. Its maximum concentration and effectiveness occurs during the fertile period, where there is a predominance of lactobacilli. When it is reduced (microbiota dysbiosis) leads to bacterial vaginosis and candida vaginitis which are common diseases in women. Consequently, instillation of lactobacilli in the vagina has beneficial effects on the symptomatology and prognosis of these illnesses. Breast milk is one of the key factors in the development of gut microbiota of the infant. There is an enteric-breast circulation, which is higher at the end of pregnancy and during breastfeeding. This circulation could explain the modulation of the breast microbiota by using probiotics. It could have a positive impact not only for the health of the mother, who would reduce the incidence of mastitis, but also for their infant. The use of probiotics is a hopeful alternative in various gynecological pathologies. However, it's is necessary first some well-designed, randomized trials with standardized methods and with a significant number of patients in order to confirm its benefits and allow us its use in protocols.
