BACKGROUND: vaginal microbiotas can be clustered into five different possible categories (CST I to V), according to their bacterial dominance. In CST I. the dominance of lactobacillus crispatus seems to correlate with better vaginal health and with a lower incidence of sine causa infertility. pretenn delivery, bacterial vaginosis, and viral (including human papillomavirus; HPV) infection. according to the same method of classifying the vaginal microbiome, CST IV (non-lactobacillus-dominated) demonstrates a higher incidence of disorders.METHODS: In an open, non-controlled study, we enrolled 35 HPV-positive women who mostly (N.=24) demonstrated CST IV status, with the other individuals categorized as having either CST III (N.=10) or CST II (N.=1) microbiotas.RESULTS: After 90 days of oral treatment with a probiotic (L. crispatus M247) we observed a reduction of approximately 70% in HPV positivity and a significant change in CST status with 94% of women now classified as CST I.CONCLUSIONS: despite the limitations of our study, it is the first demonstration that it is possible to intervene orally with an L. crispatus probiotic to bring about a change in CST status and, in parallel, increased HPV clearance.

Abstract

BACKGROUND: vaginal microbiotas can be clustered into five different possible categories (CST I to V), according to their bacterial dominance. In CST I. the dominance of lactobacillus crispatus seems to correlate with better vaginal health and with a lower incidence of sine causa infertility. pretenn delivery, bacterial vaginosis, and viral (including human papillomavirus; HPV) infection. according to the same method of classifying the vaginal microbiome, CST IV (non-lactobacillus-dominated) demonstrates a higher incidence of disorders.METHODS: In an open, non-controlled study, we enrolled 35 HPV-positive women who mostly (N.=24) demonstrated CST IV status, with the other individuals categorized as having either CST III (N.=10) or CST II (N.=1) microbiotas.RESULTS: After 90 days of oral treatment with a probiotic (L. crispatus M247) we observed a reduction of approximately 70% in HPV positivity and a significant change in CST status with 94% of women now classified as CST I.CONCLUSIONS: despite the limitations of our study, it is the first demonstration that it is possible to intervene orally with an L. crispatus probiotic to bring about a change in CST status and, in parallel, increased HPV clearance.
