What this Trial Is About
Researchers are studying pregnant women to understand how microbiome, proteomics, and serum markers might help predict preeclampsia, a condition that can affect pregnancy. This multicenter, prospective cohort study also aims to explore how these biological markers relate to pregnancy outcomes such as complications during pregnancy, delivery, and the newborns health. The study is conducted by Zhujiang Hospital and focuses on maternal and infant microecology in China. Pregnant women who come to the hospital before 14 weeks of gestation are invited to participate. After consenting, they will complete a questionnaire and provide samples including urine, serum, saliva, vaginal swabs, and feces at several points during pregnancy 11-14 weeks, 22-28 weeks, 32-34 weeks, and at delivery. If possible, placenta, cord blood, and amniotic fluid will also be collected at delivery. Women with preeclampsia during pregnancy will be followed up with similar sampling up to two years after their child is born. Participants will be monitored through various laboratory assessments including 16S rRNA gene sequencing for microbiome analysis and advanced techniques like MALDI-TOF peptidomics and mass spectrometry metabonomics. The study will also evaluate patient-specific risk of preeclampsia using clinical measurements such as mean arterial pressure and serum placental growth factor. Follow-up visits after delivery will occur at 6 weeks, 6 months, 1 year, and 2 years to continue monitoring maternal and infant health. The primary outcomes include microbiome, proteomics, and metabonomics data collected over 34 months, with secondary outcomes assessed over 10 months.
