Compositions for use in the prevention or treatment of necrotizing enterocolitis in infants and young children
The invention discloses a composition comprising an oligosaccharide mixture, said oligosaccharide mixture comprising from 40 to 80 wt % of fucosylated oligosaccharide(s), from 10 to 50 wt % of N-acetylated oligosaccharide(s), from 5 to 40 wt % of sialylated oligosaccharide(s) and from 0 to 20 wt % of precursor(s) of human milk oligosaccharide, for use in preventing and/or in treating necrotizing enterocolitis in infants and young children.
1. A method for treating necrotizing enterocolitis in an infant or young child in need thereof, the method comprising: administering to the infant or young child a composition comprising an oligosaccharide mixture, the oligosaccharide mixture comprising from 60 to 65 wt % of 2′-fucosyllactose (2-FL), from 20 to 25 wt % of lacto-N-tetraose (LNT) and lacto-N-neotetraose (LNnT), and from 10 to 15 wt % of 6′ sialyllactose (6-SL), and the composition comprising the LNT and the LNnT in a LNT:LNnT ratio between 2:1 and 1:1.
2. The method according to claim 1 , wherein the oligosaccharide mixture further comprises 1 to 15 wt % of sialic acid.
3. The method according to claim 1 , wherein the oligosaccharide mixture further comprises 1 to 10 wt % of sialic acid.
4. The method according to claim 1 , wherein the oligosaccharide mixture further comprises an additional fucosylated oligosaccharide selected from the group consisting of 3-fucosyllactose (3-FL), difucosyllactose, lacto-N-fucopentaose I, lacto-N-fucopentaose II, lacto-N-fucopentaose III, lacto-N-fucopentaose V, lacto-N-difucohexaose I, lacto-N-fucohexaose, fucosyllacto-N-hexaose, fucosyllacto-N-neohexaose, difucosyllacto-N-hexaose I, difuco-lacto-N-neohexaose, difucosyllacto-N-neohexaose I, difucosyllacto-N-neohexaose II, fucosyl-para-Lacto-N-hexaose, tri-fuco-para-Lacto-N-hexaose I and combinations thereof.
5. The method according to claim 1 , wherein the oligosaccharide mixture further comprises 3′ sialyllactose (3-SL).
6. The method according to claim 1 , wherein the oligosaccharide mixture further comprises fucose.
7. The method according to claim 1 , wherein the composition further comprises at least one probiotic in an amount of from 10 3 to 10 12 cfu/g of the composition (dry weight).
8. The method according to claim 1 , wherein the composition is a nutritional composition, a preparation or a food product.
9. The method according to claim 1 , wherein the composition is selected from the group consisting of an infant formula, a starter infant formula, a follow-on infant formula, a baby food, an infant cereal composition, a growing-up milk, a fortifier and a supplement.
10. The method according to claim 1 , wherein the composition is administered before and/or during a weaning period.
11. The method according to claim 1 , wherein the individual is selected from the group consisting of a preterm infant, a small for gestational age infant, and an infant born by C-section.
12. The method according to claim 1 , wherein the LNT:LNnT ratio is between 2:1.2 and 2:1.6.
13. The method according to claim 1 , wherein the oligosaccharide mixture further comprises up to 20 wt % of sialic acid.
14. A method for treating necrotizing enterocolitis in an infant or young child in need thereof, the method comprising: administering to the infant or young child a composition comprising an oligosaccharide mixture, the oligosaccharide mixture comprising
from 0.5 to 10 g/L of 2-FL,
from 0.1 to 4 g/L of LNnT,
from 0.1 to 4 g/L of LNT,
from 0.1 to 4 g/L of 6-SL, and
from 0 to 3 g/L of sialic acid, and the composition comprising the LNT and the LNnT in a LNT:LNnT ratio between 2:1 and 1:1.
