What this trial studies

This clinical trial investigates the effects of maternal perinatal probiotic supplementation on neonatal jaundice and related microbiomes. A total of 94 pregnant women will be randomly assigned to receive either the probiotic product Vivomixx® or a placebo starting from 36 weeks of gestation until one week postpartum. The study will collect biological samples from mothers and infants to analyze the impact of probiotics on bilirubin levels and microbiome composition. The trial aims to provide insights into how probiotics can influence neonatal health outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women aged 18-45 years with a singleton pregnancy between 28-34 weeks of gestation.

Not a fit: Patients with fetal abnormalities or those on antibiotic medication during the study period may not benefit from this intervention.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of neonatal jaundice and its complications.

How similar studies have performed: While the use of probiotics in pregnancy is being explored, this specific approach to prevent neonatal jaundice is relatively novel and has not been extensively tested in prior studies.
