Assessment of the Impact of Type of Probiotic, Delivery Type and Feeding Type on Baby's Microbiota After Dysbiotic Delivery

Dysbiosis Clinical Trial

Official title:
Assessment of the Impact of Type of Probiotic, Delivery Type and Feeding Type on Baby's Microbiota After Dysbiotic Delivery

Clinical Trial Summary

This study aims to determine the effect of three factors (delivery type, feeding type and the use of two different dietary supplements) on rebiosis after disbiotic delivery. This is a randomized, single-blinded study with two parallel arms. Group 1 will receive L. reuteri (10^8 CFU) once a day, group 2 will receive B. longum and P. Pentosaceus (10^9 CFU) once a day.

Clinical Trial Description

Gut colonization during the first days of life represents the start of the infant's own microbiota. This process is influenced by different factors: delivery type, feeding type, antibiotic treatment, etc. On the one hand, vaginally delivered babies are in contact with mother's vaginal and faecal microbiota. This fact will drive a neonatal gut colonization composed of vagina-associated bacteria. In contrast, babies born by C-section are more susceptible to be colonized by microorganisms present in the mother's skin. On the other hand, antibiotic administration during vaginal delivery also produces alterations in the vaginal microbiota of the mother. Described scenarios have been correlated to immunological and metabolic diseases such as asthma, allergies, diabetes or obesity. Moreover, disbiosis has also been associated to functional gastrointestinal disorders (FGID) in babies such as infant colic and functional constipation. After a disbiotic delivery, medical doctors usually recommend the use of probiotics to prevent rebiosis. Since the probiotics. L. reuteri, and B. longum and P. Pentosaceus have shown efficacy on FGID amelioration in previously published articles, these two probiotics were selected for the present study. All together, this study aims to characterize the role of three different parameters: type of probiotic, delivery type and feeding type. ;
