NCT06241222

Brief Summary

This study aim to evaluate the composition and origin of the neonatal gut microbiota after birth and Probiotic intervention. Samples were obtained from a total of 30 pregnant individuals and their offspring, divided into control group and porbiotics group. Postpartum human milk and infant fecal specimens were collected for a period of 6 months. The samples were analyzed using 16S rRNA amplicon sequencing of the V3-V4 region to evaluate the microbial composition. The Shannon index, Simpson index and nonmetric multidimensional scaling were used to evaluate the diversity of the microbiota, while the co-occurrence network and LEfSe were used to evaluate the characteristics of the microbiota of pregnancies and their infants in each groups.

Outcome Measures

Primary Outcomes (1)

  • 16S rRNA amplicon sequencing of the V4 region

    Difference analysis of each group was performed. All the measurement data are presented as the mean ± standard error. Assessments of Operational Taxonomic Units differences in the probiotic group and control group were performed using independent sample t tests, and P \< 0.05 was considered to indicate statistical significance. Other outcomes were analyzed using multiple linear regression. All data were analyzed using SPSS 23.0 statistical software (SPSS, Inc., Chicago, IL, USA).

Study Arms (2)

control group

NO INTERVENTION

pregnancies in control group need no intervention.

probiotics group

EXPERIMENTAL

pregnancies in probiotics group need probiotics management

Drug: Probiotic Blend Oral Tablet

Interventions

In our study, fourteen pregnant women were randomly assigned to the probiotic group, and the rest were assigned to the control group. After enrollment, pregnant women in the probiotic group received a combination of living Bifidobacterium longum (5 ∗ 106 CFU), Lactobacillus delbrueckii bulgaricus (5 ∗ 105 CFU) and Streptococcus thermophilus (5 ∗ 105 CFU) tablets produced by Neimengu Shuangqi Pharmaceutical Co., Ltd. Pregnant individuals in the probiotic group were administered two tablets twice a day (2 g/d) until natural delivery
