Probiotic Supplementation to Improve the GUT Microbiota of Very Low Birth Weight, a Pilot Study

This pilot trial is designed to investigate the benefits of the use of probiotics in GUT microbiota development and/or immunological biomarkers and how this can be related with the clinical status of very low birth weight preterms during their first weeks of life at the neonatal intensive care unit(NICU).

Detaljeret beskrivelse

This pilot trial is designed to investigate the benefits of the use of mixtures of probiotics isolated from human milk in GUT microbiota development and/or immunological biomarkers. Furthermore, the relationship between evaluated parameters and the clinical status of very low birth weight preterms during their first weeks of life at the NICU will be analysed.

Intervention / Behandling
Andet: Probiotics supplementation
Five very low birth weight (VLBW) infants enrolled within 2 days of birth, with a weight < 1300 g and gestational age < 29 weeks and without any malformation or metabolic disease at birth were supplemented with two daily doses of a mixture of "Bifidobacterium breve" and "Lactobacillus salivarius" , probiotic strains isolated from human milk during their first weeks of life. The lyophilized powder has contained at least 1x10^9 colony forming units (CFU) per doses of each one of the probiotic bacteria.
blood and fecal samples were collected from five VLBW preterms which were supplemented with a probiotic mixture of Bifidobacterium breve / Lactobacillus salivarius isolated from human milk
Andre navne:
  • "Bifidobacterium breve / Lactobacillus salivarius mixture"
