Gut Microbiota, SCFAs and Glucolipid Metabolism in Pregnant Women With Abnormal Fetal Size and Their Newborns

Gut Microbiota Clinical Trial

Official title:
Study on the Relationship of Gut Microbiota and Changes of SCFAs With Glucolipid Metabolism in Pregnant Women With Abnormal Fetal Size and Their Newborns

Clinical Trial Summary

Abnormal fetal size includes fetal growth restriction and fetal macrosomia. Onset is closely related to maternal nutrition metabolism. The specific correlation and mechanism is unclear, and there are no effective measures for early diagnosis and treatment. Previous study found that maternal gut microbiota participates in the material metabolism throughout the pregnancy. Insulin sensitivity in pregnant women, and intrauterine environment under abnormal blood glucose and lipid metabolism are important for the gut microbiota of newborns and even they grow up. However, changes in gut microbiota are the cause of the disease or the outcome is not yet clear. Short chain fatty acids (SCFAs) are produced from soluble dietary fibers in the diet by colon bacteriolysis. Studies have found that gut microbiota can regulate insulin sensitivity and glucose and lipid metabolism disorders through SCFAs. Therefore, this research group uses the gut microbiota as a new idea to studythe relationship of gut microbiota characteristics and level's change of SCFAs with glucolipid metabolism and insulin sensitivity in pregnant women with abnormal fetal size and their newborns through 16S-rRNA high-throughput sequencing, pyrosequencing, and gas chromatography-mass spectrometry, so we can reveal the role of gut microbiota in the pathogenesis of abnormal fetal size and explore targeted rational dietary adjustment and SCFAs reconstruction of gut microbiota to improve maternal and neonatal pregnancy outcomes.
