Trial Outcomes & Findings for Effect of Milk Oligosaccharides and Bifidobacteria on the Intestinal Microflora of Children With Autism (NCT NCT02086110)

NCT ID: NCT02086110

Last Updated: 2019-08-01

Results Overview

The stool microbiome composition will be analyzed through next generation sequencing and quantitative polymerase chain reaction. Overall bacterial composition change is reported here, as change in enterotype from before prebiotic only treatment to after prebiotic treatment, for all subjects. Enterotypes were organized into four categories for analysis: a community high in Prevotella ("Prevotella"), a community high in Bifidobacterium ("Bifidobacterium"), a community high in Bacteroides ("Bacteroides"), and a mixed community ("Mixed") that did not fall into one of the other three enterotypes but instead consisted of a varied combination of bacteria, including among others Akkermansia, Collinsela, Prevotella, and/or Bacteroides.

Prebiotic Only First, Then Synbiotic
This group will receive prebiotic only (bovine milk oligosaccharides, administered orally twice per day for a daily total of 0.3 g per pound of body weight) for the first five weeks, followed by a two week break with no treatment, and then will receive the synbiotic (Bifidobacterium infantis (10 billion CFU) twice a day plus 0.3 g per pound body weight of bovine milk oligosaccharides in two divided doses per day orally) for the next five weeks.
Synbiotic First, Then Prebiotic Only
This group will receive the synbiotic (Bifidobacterium infantis (10 billion CFU) twice a day plus 0.3 g per pound body weight of bovine milk oligosaccharides in two divided doses per day orally) for the first five weeks, followed by a two week break with no treatment, and then will receive the prebiotic only (bovine milk oligosacharrides, administered orally twice per day for a daily total of 0.3 g per pound of body weight) for the next five weeks.

PRIMARY outcome

Timeframe: Five weeks

Population: In the Prebiotic First group, 1 subject withdrew consent prior to providing stool sample. In the Synbiotic First group, 1 subject withdrew consent prior to starting prebiotic treatment, and 1 subject was unable to provide a stool sample for analysis.

The stool microbiome composition will be analyzed through next generation sequencing and quantitative polymerase chain reaction. Overall bacterial composition change is reported here, as change in enterotype from before prebiotic only treatment to after prebiotic treatment, for all subjects. Enterotypes were organized into four categories for analysis: a community high in Prevotella ("Prevotella"), a community high in Bifidobacterium ("Bifidobacterium"), a community high in Bacteroides ("Bacteroides"), and a mixed community ("Mixed") that did not fall into one of the other three enterotypes but instead consisted of a varied combination of bacteria, including among others Akkermansia, Collinsela, Prevotella, and/or Bacteroides.

SECONDARY outcome

Timeframe: Five weeks

Population: 1 subject was unable to provide blood specimens throughout the study due to significant anxiety with regard to venipuncture, so only 7 subjects' serum was available for analysis.

Luminex technology will be used to determine a serum immune profile of each participants in response to the study supplement. This profile included assessment of change in percentage of stimulated CD4+ T cells producing intracellular IL-13 before and after Synbiotic treatment ("Post-Synbiotic % IL-13"), and assessment of change in percentage of stimulated CD8+ T cells producing TNF-alpha before and after Prebiotic Only treatment ("Post-Prebiotic % TNF-alpha"). Results are reported here for all subjects regardless of treatment order assignment. Decrease in inflammatory cytokines IL-13 and TNF-alpha is interpreted as a positive outcome.
