Composition comprising HMSs/HMOs and use thereof
The application relates to a method for the prophylaxis or treatment of non-infectious diarrhea in a human, the method comprising administering to the human an effective amount of one or more human milk oligosaccharides.
1. A method comprising:
selecting a non-infant human experiencing one or more symptoms associated with diarrhea-predominant irritable bowel syndrome (“IBS-D”);
selecting an effective amount of a mixture of the human milk oligosaccharides (“HMOs”) 2′-fucosyllactose (2′FL) and lacto-N-neotetraose (LNnT) for administration to the non-infant human that when administered to the non-infant human reduces a level of intestinal dysbiosis by increasing the relative abundance of Bifidobacterium adolescentis ; and
increasing the relative abundance of Bifidobacterium adolescentis in the gastrointestinal microbiota of the non-infant human and reducing the one or more symptoms associated with the IBS-D in the non-infant human by administering to the non-infant a daily dose of the selected effective amount of the mixture of 2′FL and LNnT.
2. The method of claim 1 , further comprising improving an impaired mucosal barrier in the non-infant human by administering to the non-infant human the selected effective amount of the mixture of 2′FL and LNnT.
3. The method of claim 1 , wherein reducing the one or more symptoms associated with IBS-D comprises reducing bowel movement frequency and improving stool consistency.
4. The method of claim 1 , further comprising reducing levels of an inflammatory marker in the non-infant human by administering to the non-infant human the selected effective amount of the mixture of 2′FL and LNnT.
5. The method of claim 1 , further comprising administering with the mixture of 2′FL and LNnT, one or more additional HMOs selected from the group consisting of 3-fucosyllactose (3FL), difucosyllactose (DFL), lacto-N-tetrose (LNT), 3′-sialyllactose (3′SL), 6′-sialyllactose (6′SL), lacto-N-fucopentaose I (LNFP-I), and combinations thereof.
6. The method of claim 1 , wherein the mass ratio of the 2′FL to the LNnT is from about 4:1 to 2:1.
7. The method of claim 1 , wherein the selected effective amount of the administered mixture of 2′FL and LNnT is from about 3 g to about 7.5 g per day.
8. The method of claim 1 , further comprising reducing levels of Escherichia and Clostridium in the non-infant human.
9. A method comprising:
selecting a non-infant human experiencing lactose intolerance and one or more symptoms associated with the lactose intolerance, the symptoms selected from diarrhea, abdominal pain, cramping, bloating, and flatulence;
selecting an amount of a mixture of the human milk oligosaccharides (“HMOs”) 2′-fucosyllactose (2′FL) and lacto-N-neotetraose (LNnT) effective for increasing the relative abundance of Bifidobacterium adolescentis in the gastrointestinal microbiota of the non-infant human; and
increasing the relative abundance of Bifidobacterium adolescentis in the gastrointestinal microbiota of the non-infant human and reducing at least one of the one or more gastrointestinal symptoms of the lactose intolerance by administering to the non-infant human a daily dose of the selected effective amount of the mixture of 2′FL and LNnT.
10. The method of claim 9 , wherein:
after an initial treatment period, the non-infant human reintroduces consumption of dairy foods; and administering the mixture reduces the likelihood of the symptoms of lactose intolerance occurring in the non-infant human after the initial treatment period.
11. A method comprising:
selecting a non-infant human commencing an antibiotic therapy;
selecting an amount of a mixture of the human milk oligosaccharides (“HMOs”) 2′-fucosyllactose (2′FL) and lacto-N-neotetraose (LNnT) effective for increasing the relative abundance of Bifidobacterium adolescentis in the gastrointestinal microbiota of the non-infant human; and
increasing the relative abundance of Bifidobacterium adolescentis in the gastrointestinal microbiota of the non-infant human and reducing the likelihood of the non-infant human experiencing gastrointestinal dysbiosis, diarrhea, or both, associated with the antibiotic therapy by administering to the non-infant human a daily dose of the selected effective amount of the mixture of 2′FL and LNnT.
12. The method of claim 11 , further comprising reducing levels of Clostridium in the non-infant human.
13. The method of claim 12 , further comprising reducing the likelihood of the non-infant human experiencing diarrhea associated with the Clostridium during the antibiotic therapy.
14. The method of claim 12 , further comprising reducing the likelihood of the non-infant human experiencing diarrhea associated with the Clostridium during a post antibiotic therapy period of up to four weeks.
15. The method of claim 9 , further comprising reducing hydrogen gas production in the gastrointestinal tract of the non-infant human.
16. The method of claim 9 , further comprising increasing the beta-galactosidase activity in the gastrointestinal tract of the non-infant human.
