Prevention of preterm birth using a mid-pregnancy microbial diagnostic test and antibiotic/probiotic treatment regimen

Bacterial infections are a leading cause of preterm birth. This project team developed a vaginal bacterial DNA assay, the GLU test, capable of predicting 45% of spontaneous preterm birth (sPTB) cases. This study will use this test to identify women at high risk and offer antimicrobial/probiotic treatments to prevent sPTB.

Research overview

Preterm birth is the leading cause of death and disability in children under five years age. Bacterial infection accounts for at least 25% of all cases of preterm birth, especially spontaneous preterm births, with the vast majority of these originating in the vagina.

This randomised clinical trial is employing a new diagnostic test to predict women at high risk of preterm birth based on their vaginal microbial DNA profile. Those randomised to the intervention arm of the trial will receive a new antibiotic/probiotic treatment regimen to try and prevent this birth outcome.

This research has the potential to reduce the number of preterm infants born in WA each year by 715 (from a total of 2,383 preterm infants), providing a lifesaving solution for West Australian children that will substantially lower associated infant mortality and morbidity.
