Bacterial vaginosis is considered the most common cause of vaginal infection among pregnant and non-pregnant women, with a prevalence between 4.9% and 36.0% (data reported by European and American studies).
In addition, about 75% of women of reproductive age have at least one episode of vulvovaginal candidiasis (VVC) and in about half of them, two or more relapses occur. The most common pathogen is Candida albicans, which is isolated in 85-90% of cases.
Asymptomatic colonization with Candida spp. is also common. It can be found in about one-third of women without symptoms and was identified in 70% during a one-year observation period.
The onset of these pathologies is linked to a common phenomenon: the alteration of the vaginal bacterial flora, also known as dysbiosis. It is a problem that can quickly occur in a woman’s life and that, often, common antibiotic treatments struggle to eliminate definitively.
Respecta®: a product able to counteract vaginal dysbiosis
The Research and Development laboratories of Biofarma Group, which have always been active in the creation of products able to support women’s health, have developed a formulation that can represent a valid aid in case of vaginal dysbiosis and associated disorders.
The active ingredients selected for the formulation are the probiotic strains L. acidophilus GLA-14 and L. rhamnosus HN001, and lactoferrin.
The choice of lactobacilli strains stems from the need to solve the problem of the inability of antibiotics to restore normal vaginal bacterial flora spontaneously. This can only be achieved through recolonization of the ecosystem by lactobacilli, which play the critical role of creating a barrier against pathogens.
This is why numerous studies have focused on the search for a solution or on the observation of the effects deriving from the integration of these microorganisms. Specifically, a study observed the effects of the strains selected for this formulation, L. acidophilus GLA-14 and L. rhamnosus HN001, on four bacteria responsible for infections and recurrences. The results showed the ability of the lactobacilli combination to inhibit the growth of all pathogens tested.
Lactoferrin also has a substantial impact on microbiota growth and diversity as it can inhibit the development of a wide range of pathogenic bacteria and, at the same time, promote the growth of beneficial microorganisms, such as lactobacilli and bifidobacteria.
The synergistic action of L. acidophilus GLA-14, L. rhamnosus HN001 and lactoferrin is therefore combined in an innovative nutraceutical formulation with a proven and clinically studied mechanism of action to restore and maintain a healthy vaginal flora and promote the health of the genitourinary tract: Respecta®.
The product’s efficacy was tested in vitro in the first phase and in vivo in the second phase, which involved several trials performed on samples of healthy women and subjects suffering from vaginal infections.
Specifically, Respecta® was tested on a sample of 40 healthy women and 40 women with an intermediate imbalance of the vaginal flora. In both cases, the ability of the components of the formulation to colonize the vaginal tract was observed, thus ensuring the maintenance of well-being.
The product was also tested on samples of women suffering from bacterial vaginosis and vulvovaginal candidiasis in two different trials. In both cases, the results showed the formulation’s ability to improve symptoms, increase the cure rate and lower the number of cases of recurrence of diseases.
The presence of tests carried out both on healthy women and on women with cases of vaginal dysbiosis, or even already related diseases, highlights a dual function of the product: both preventives aimed at maintaining the balance of bacterial flora and adjuvant action of the treatment of infections of the vaginal tract.
