Syphilis in pregnancy: improved tests and mother–baby immune responses

Syphilis in Pregnancy Study (SIPS): Molecular Diagnostics and Maternal and Infant Immune Response to Infection

NIH-funded research University of Alabama at Birmingham · NIH-11376430

What this research studies

If you join, you'll be enrolled with other pregnant people who have confirmed syphilis or who do not have syphilis and followed through the first year after delivery. The team will collect blood and other samples from mothers and infants at multiple times to run molecular tests and measure immune responses. Researchers will compare 750 women with syphilis and their exposed infants to 750 pregnant controls to learn how infection moves from mother to baby and when current tests miss cases. The work is observational, so care follows local clinical guidelines while samples and data are used to improve diagnostics and understanding of outcomes.

Who could benefit from this research

Good fit: Ideal candidates are pregnant people in the study regions (Cameroon or Zambia) with confirmed syphilis or pregnant controls willing to provide samples and attend follow-up through 12 months postpartum.

Not a fit: People who are not pregnant, who live outside the study locations, or who are unwilling to provide repeated samples and attend follow-up visits are unlikely to benefit directly from participation.

Why it matters

Potential benefit: If successful, this work could lead to earlier and more accurate testing for syphilis in pregnancy and newborns, which could reduce stillbirths and newborn illness.

How similar studies have performed: Smaller observational and laboratory studies have identified problems with current tests and shown promise for molecular approaches, but this large, paired mother–infant cohort is a newer and more comprehensive effort.
