Markers of intestinal immune activation and inflammation are not associated with preterm birth among women with low level HIV viremia.

Background: Maternal markers of intestinal immune activation may be used to predict preterm birth (PTB) in pregnant women living with HIV.

Methods: This study used de-identified samples from the International Maternal Pediatric Adolescent AIDS Clinical Trials Group (IMPAACT) Protocol P1025 study. Singleton pregnancies with ≥3 ml plasma available and HIV viral load ≤400 copies/ml within 4 weeks of specimen collection were included.
