Vaginal Microbiome and the Risk of Preterm Birth in Women Living With HIV: A Scoping Review.

ABSTRACT: There are sparse data on the role of the vaginal microbiome (VMB) in pregnancy among pregnant women living with HIV (PWLWH) and its association with spontaneous preterm birth (sPTB). We conducted a scoping review to assess associations between vaginal microbiota and sPTB among PWLWH. Three studies were included, representing a total of 180 PWLWH out of 652 total pregnancies. All studies used modern DNA sequencing methods (16S rRNA amplification, metagenomics, or metatranscriptomics). PWLWH had higher VMB richness and diversity compared to HIV-uninfected pregnant women and higher sPTB rates in two of three studies. A higher proportion of sPTB among PWLWH was observed in those with Lactobacillus-deficient, anaerobe-dominant vaginal microbiota. In two of three studies, higher concentrations o
