- Spontaneous preterm birth has enormous consequences for newborns, children, and families. Intra-amniotic inflammation (IAI) is the leading cause of spontaneous preterm delivery, mainly at earlier gestational ages. Amniocentesis is the only method used to identify IAI in clinical practice. Although it is an invasive procedure with a very low risk of complications, many women and physicians are hesitant about amniocentesis on this indication. This has been an incentive to explore IAI and the intra-amniotic environment through noninvasive techniques, such as sampling cervical mucus, vaginal fluid, or maternal blood. With this overview, we aim to provide a concise update on the state of the art of the noninvasive sampling of the intrauterine environment in women with preterm labor and intact membranes. So far, it is unknown whether this screening helps improve our knowledge about the impact of IAI on the neonatal and long-term outcome, but we believe it merits this review.

- The aim of this study was to investigate whether a previously reported vaginal fluid point-of-care interleukin (IL)-6 cut-off value of 2,500 pg/mL can be used for the identification intra-amniotic inflammation in women with preterm prelabor rupture of membranes (PPROM) between 34 and 37 weeks.A prospective cohort study was conducted in women with singleton gestation complicated by PPROM between 34 + 0 and 36 + 6 weeks. Vaginal fluid was successfully obtained in 118 women from the posterior vaginal fornix via aspiration using a sterile urine sample tube with a suction tip. Amniotic fluid was obtained via transabdominal amniocentesis. IL-6 concentrations were assessed in both fluids immediately after sampling. Intra-amniotic inflammation was defined as an amniotic fluid point-of-care IL-6 concentration of ≥745 pg/mL.The tested vaginal fluid IL-6 cut-off value had a sensitivity of 91%, specificity of 91%, positive predictive value of 50%, negative predictive value of 99%, positive likelihood ratio of 9.7, and negative likelihood ratio of 0.1 for the identification of intra-amniotic inflammation.The point-of-care vaginal fluid IL-6 test with a cut-off value of 2,500 pg/mL shows good sensitivity, specificity, and negative predictive value for the identification of intra-amniotic inflammation in PPROM between 34 and 37 weeks.
