The vaginal microbiome of pregnant people living with HIV on antiretroviral therapy in the Democratic Republic of Congo: a pilot study and global meta-analysis

Resumo original em inglês

O que aconteceu

Human immunodeficiency virus (HIV) remains prevalent in sub-Saharan Africa, where it has been linked to adverse birth outcomes. Suboptimal vaginal microbiomes (VMBs) have shown similar links. This pilot study fills critical gaps in understanding how HIV interacts with the pregnant VMB in populations underrepresented in microbiome research, like the Democratic Republic of the Congo (DRC). We identified maternal systemic immune factors associated with suboptimal VMBs that have been linked to poor birth outcomes. In a global meta-analysis, we found significant taxonomic and functional differences in the VMBs between pregnant people living with and without HIV, revealing potential biomarkers that increase the risk of adverse birth outcomes. These findings provide crucial insights into VMB features that may influence pregnancy health in PLWH-ART, guiding future research and tailored interventions to support safer pregnancies in the DRC and similar populations.This study is registered with NCT03048669.
