Hypothesis
Depot medroxyprogesterone acetate (DMPA) use alters immune responses and structural integrity in the ectocervical mucosa.
Conclusion
DMPA use is associated with distinct transcriptional profiles in the ectocervical mucosa, including upregulation of immunoglobulin genes and downregulation of genes related to epithelial barrier integrity.
Supporting Evidence
- DMPA users showed upregulation of immunoglobulin genes across the ectocervical mucosa.
- Downregulated genes were associated with disrupted epithelial barrier integrity.
- Spatial transcriptomics revealed distinct transcriptional profiles in different mucosal layers.
Takeaway
Women using a certain birth control shot (DMPA) show changes in their cervix that might make them more likely to get infections.
Methodology
Ectocervical tissue samples were analyzed using spatial transcriptomics and gene set enrichment analyses.
Potential Biases
Sample selection based on RNA quality and morphology may introduce bias.
Limitations
The study is observational and cannot imply causation; the sample size is modest.
Participant Demographics
Participants were Kenyan sex workers aged 18-50, with a history of DMPA use for at least 6 months.
