Feeding the Preterm Gut Microbiota - Impact of Infant-feeding on Preterm Gut Microbiota Development (FEEDMI)
Study Overview
Detailed Description
Meconium and the additional 3 fecal samples will be collected from preterm infants by the nursing team of MAC Neonatology Unit. Fecal samples will be collected every 7 days, during 21 days, from diapers into sterile tubes. Mothers will be asked to collect their own fecal samples with an appropriate stool collection kit (EasySampler®) and will be invited to complete a semi-quantitative food frequency questionnaire, previously validated for the Portuguese population.
Infant-feeding profile (breast milk, donor human milk or formula) of preterm infants will be recorded every day to select the most representative (>50 %) type of infant-feeding received during the 7 days prior to each fecal sample collection.
Additionally, detailed clinical data will be collected during the preterm infant enrollment in the study. Personal clinical data includes sociodemographic information and clinical intrapartum and postpartum outcomes, such as newborn's weight, days of antibiotic exposure, number of total days of hospitalization and others outcomes related to the preterm clinical evolution.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Very Preterm Infants
Newborn infants with less than 32 weeks admitted in the NICU.
|
Preterm infants hospitalized in the NICU can be feed by three different types of infant feeding, such as breast milk, donor human milk and/or formulas.
|
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes from baseline intestinal microbiota composition of preterm infants at 7, 14 and 21 days.
Time Frame: The first fecal sample (meconium) of preterm infants will be collected. Afterwards, fecal samples will be collected every 7 days, during 21 days.
|
The intestinal microbiota profile of preterm infants will be evaluated over time.
|
The first fecal sample (meconium) of preterm infants will be collected. Afterwards, fecal samples will be collected every 7 days, during 21 days.
|
Changes from baseline intestinal microbiota composition of preterm infants in relation to infant-feeding profile (breast milk, donor human milk or formula) at 7,14 and 21 days.
Time Frame: Infant-feeding type of preterm infants before the first, second, third and fourth collection will be recorded during these 21 days.
|
Infant-feeding profile (breast milk, donor human milk or formula) will be recorded every day to select the most representative type of infant-feeding (> 50 %) received during the 7 days prior to each fecal sample collection.
|
Infant-feeding type of preterm infants before the first, second, third and fourth collection will be recorded during these 21 days.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Maternal intestinal microbiota composition, analyzed by RT-PCR.
Time Frame: Maternal fecal samples will be collected after delivery up to 1 week.
|
Mother's will be asked to collect their own fecal samples for gut microbiota analysis by RT-PCR.
An appropriate stool collection kit will be provided (EasySampler Stool Collection kit).
|
Maternal fecal samples will be collected after delivery up to 1 week.
|
Changes in maternal gut microbiota in relation to clinical variables described below
Time Frame: Clinical variables will be collected daily, until study completion an average of 2 years.
|
Changes in intestinal microbiota profile of preterm infants' mothers will be evaluated in relation to mode of delivery, mother's gestational age, dietary pattern during pregnancy, weight gain in gestation and antibiotic exposure.
|
Clinical variables will be collected daily, until study completion an average of 2 years.
