How HIV-related vaginal viruses may affect early births in pregnant South African women

Influence of HIV infection on vaginal virome and risk of preterm birth in pregnant South African women

NIH-funded research Seattle Children's Hospital · NIH-11176710

This work looks at whether differences in vaginal viruses in pregnant women with HIV help explain their higher chances of having a preterm birth.

What this research studies

You would be asked to provide vaginal swabs and health information during pregnancy so the team can compare the types and amounts of viruses in the vagina of women with and without HIV. The researchers will sequence viral and bacterial genetic material, measure signs of inflammation, and track pregnancy outcomes such as preterm birth. They will also compare women on different antiretroviral treatments to see if medications or HIV itself relate to viral changes and birth risk. The goal is to connect viral patterns to early labor and point to ways to lower preterm birth risk.

Who could benefit from this research

Good fit: Pregnant women in the study region (South Africa) both living with HIV and without HIV who are willing to provide vaginal samples and pregnancy outcome information.

Not a fit: People who are not pregnant or who live outside the study sites in South Africa would not be eligible and are unlikely to receive direct benefit from this study.

Why it matters

Potential benefit: If successful, this work could identify viral or inflammatory targets that lead to new strategies to reduce preterm births among pregnant women with HIV.

How similar studies have performed: Previous research has linked changes in vaginal bacteria and the gut virome to preterm birth and HIV-related inflammation, but examining the vaginal virome specifically in pregnant women with HIV is largely new.
