While many studies use 16S rRNA gene sequencing for microbiota analysis, shotgun metagenomic sequencing offers higher taxonomic resolution and insights into microbial gene functions and pathways. This systematic review evaluates the relationship between compositional and functional changes in the vaginal microbiome during HPV infection and cervical lesion progression. A literature search was performed according to PRISMA guidelines in PubMed, Web of Science, Scopus, and ScienceDirect databases. Seven studies utilizing metagenomic sequencing in patients with HPV infection or HPV-associated cervical lesions were included. Progression from HPV infection to cervical lesions and cancer was associated with a reduction in Lactobacillus species (particularly Lactobacillus crispatus) and an enrichment of anaerobic and pathogenic species, especially Gardnerella vaginalis. Heterogeneous enriched metabolic pathways were also identified, indicating functional shifts during lesion progression. As most studies were conducted in Asia, further research in diverse regions is needed to improve the generalizability of findings. Future studies employing metagenomic sequencing may help identify biomarkers for early pre-cancerous lesions and clarify the role of vaginal microbiota in persistent HPV infection and cervical dysplasia.<\/jats:p>","DOI":"10.3390\/ijms26094258","type":"journal-article","created":{"date-parts":[[2025,4,30]],"date-time":"2025-04-30T05:50:17Z","timestamp":1745992217000},"page":"4258","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Association Between Vaginal Microbiota and Cervical Dysplasia Due to Persistent Human Papillomavirus Infection: A Systematic Review of Evidence from Shotgun Metagenomic Sequencing Studies"],"prefix":"10.3390","volume":"26","author":[{"given":"Guoda","family":"\u017dukien\u0117","sequence":"first","affiliation":[{"name":"Clinic of Obstetrics and Gynaecology, Faculty of Medicine, Institute of Clinical Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ramun\u0117","family":"Narutyt\u0117","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2591-6982","authenticated-orcid":false,"given":"Vilius","family":"Rudaitis","sequence":"additional","affiliation":[{"name":"Clinic of Obstetrics and Gynaecology, Faculty of Medicine, Institute of Clinical Medicine, Vilnius University, LT-03101 Vilnius, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"480","DOI":"10.1007\/s44197-024-00201-z","article-title":"The Vaginal Microbiota, Human Papillomavirus Infection, and Cervical Carcinogenesis: A Systematic Review in the Latina Population","volume":"14","author":"Mancilla","year":"2024","journal-title":"J.
