Despite the demonstrated dysbiosis of vaginal microenvironment in high-grade CIN, its post-therapy restorations remain to be poorly understood, especially in functional aspects. This study aimed to characterize temporal changes in both vaginal microbiota (VM) and metabolome (VMeta) following therapeutic elimination of high-grade CIN. We conducted a longitudinal study of 32 HPV-positive women with high-grade CIN who underwent therapeutic procedures. Vaginal swabs were collected at baseline (pre-therapy) and at 6- and 12-month follow-up visits for integrated VM and VMeta analysis. We observed a gradual restoration of\n                      <jats:italic toggle=\"yes\">Lactobacillus crispatus<\/jats:italic>\n                      levels from baseline to 12 months (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.05).

VMeta analysis revealed distinct metabolic shifts across the follow-up periods.

Integration of correlation and dynamic Bayesian network analysis indicated potential regulatory relationships and time-lag effects involving HPV infection,\n                      <jats:italic toggle=\"yes\">L. crispatus<\/jats:italic>\n                      ,\n                      <jats:italic toggle=\"yes\">Bifidobacterium<\/jats:italic>\n                      sp.,\n                      <jats:italic toggle=\"yes\">Streptococcus anginosus<\/jats:italic>\n                      ,\n                      <jats:italic toggle=\"yes\">Megasphaera<\/jats:italic>\n                      sp.,\n                      <jats:italic toggle=\"yes\">U. parvum,<\/jats:italic>\n                      and those metabolites.

Metabolically, an early rise in glycerophospholipids and fall in nucleotide metabolites is followed by later enrichment of flavonoids, lysophospholipids, bioactive amides, and amino acid derivatives. Correlation and dynamic Bayesian network analyses reveal putative regulatory links, time-lag effects, and downstream impacts of HPV clearance. These findings deliver a functional roadmap of post-therapy recovery, nominate measurable microbial\u2013metabolite milestones and candidate biomarkers for monitoring, and suggest targets for adjunct interventions to accelerate re-establishment of protective states.
