Abstract

The vaginal microbiota plays a significant role in health and disease of the female reproductive tract. Next-generation sequencing techniques based upon the analysis of bacterial 16S rRNA genes permit in-depth study of vaginal microbial community structure to a level of detail not possible with standard culture-based microbiological techniques. The human papillomavirus (HPV) causes both cervical intraepithelial neoplasia (CIN) and cervical cancer. Although the virus is highly prevalent, only a small number of women have a persistent HPV infection and subsequently develop clinically significant disease. There is emerging evidence which leads us to conclude that increased diversity of vaginal microbiota combined with reduced relative abundance of Lactobacillus spp. is involved in HPV acquisition and persistence and the development of cervical precancer and cancer. In this review, we summarise the current literature and discuss potential mechanisms for the involvement of vaginal microbiota in the evolution of CIN and cervical cancer. The concept of manipulation of vaginal bacterial communities using pre- and probiotics is also discussed as an exciting prospect for the field of cervical pathology.

  • Untreated women attending for colposcopy have a higher risk of preterm birth than women without CIN, probably explained by inherent characteristics and genetic, epigenetic, or microbiome factors.

    “Untreated women attending for colposcopy have a higher risk of preterm birth than do women without CIN, probably explained by inherent characteristics and genetic, epigenetic, or microbiome factors.40, 41, 42”

    From Comparative effectiveness and risk of preterm birth of local treatments for cervical intraepithelial neoplasia and stage IA1 cervical cancer: a systematic review and network meta-analysis (2022) · cites this paper as [42]

    The ‘Limitations of current literature and areas for future study’ section says dysbiosis increases preterm-birth risk, and the ‘Vaginal microbiota and HPV/CIN/cervical cancer’ section reports an association between CIN severity and vaginal microbiota. The paper does not establish that untreated women attending colposcopy have a higher preterm-birth risk than women without CIN, or attribute such a difference to genetic or epigenetic factors. Page numbers are unavailable in our copy. (LLM, conf=0.78)

  • Cervicovaginal microbiota plays a substantial role in persistence and regression of HPV and has implications for subsequent disease.

    “Further evidence indicates that the cervicovaginal microbiota plays a substantial role in the persistence and regression of the virus and thus has important implications for subsequent disease (Chang and Parsonnet, 2010; Mitra et al., 2016).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
