Who could benefit from this research
✓Could help
Pregnant women with confirmed syphilis and their newborns, plus pregnant controls without syphilis.
✕Less likely to help
Pregnant individuals without syphilis or without contributing samples may not directly benefit.
What this research studies
This project enrolls up to 750 pregnant women with confirmed syphilis and their exposed infants, plus pregnant controls, and collects samples through 6 months after delivery. Researchers from perinatal infectious diseases, molecular biology, and immunology will study how syphilis behaves in pregnancy and how it may be passed to the fetus. The study uses observational cohorts to describe immune responses and molecular markers that could improve diagnosis and care for mothers and babies affected by syphilis.
Why it matters
Potential benefit: If successful, findings could improve prenatal testing and treatments to reduce stillbirths, congenital syphilis, and neonatal complications.
How similar studies have gone: Prior studies have documented high risks of adverse outcomes in syphilis during pregnancy, but this project aims to expand molecular and immunologic understanding in diverse settings.
