Description

[0001] NUTRITIONAL COMPOSITION FOR STRENGHTENING THE GUT BARRIER

[0002] FIELD OF THE INVENTION

[0003] The invention relates to a nutritional composition for infants and children as well as to a medical nutritional composition. The invention further relates to the use of this nutritional composition for strengthening the gut epithelial defense and / or the gut barrier function.

[0004] BACKGROUND OF THE INVENTION

[0005] Human milk is the uncontested gold standard concerning infant nutrition. However, in some cases breastfeeding is inadequate or unsuccessful for medical reasons or not available because of a choice not to breastfeed. For such situations infant or follow-on formulas have been developed. Commercial infant formulas are commonly used today to provide supplemental or sole source of nutrition early in life. These formulas comprise a range of nutrients to meet the nutritional needs of the growing infant, and typically include fat, carbohydrate, protein, vitamins, minerals, and other nutrients helpful for optimal infant growth and development. Commercial infant formulas are designed to mimic, as closely as possible, the composition and function of human milk.

[0006] Human milk contains substantial amounts of non-digestible carbohydrates, known as human milk oligosaccharides (HMOs). Mature human milk contains 5 to 15 g / l of HMOs. It is presumed that more than 200 structurally distinct oligosaccharides are present. The building blocks of human milk oligosaccharides are the monosaccharides D-glucose (Glc), D-galactose (Gal), N-acetylglucosamine (GIcNAc), L-fucose (Fuc), and sialic acid (N-acetyl neuraminic acid (Neu5Ac). Lactose (Galp1-4Glc) forms the reducing end and can be elongated with N-acetyllactosamine repeat units (Galp1-3 / 4GlcNAc). Lactose or the polylactosamine backbone can be sialylated in a2-3 and / or a2-6 linkages and / or fucosylated in a1-2, a1-3, and / or a1 -4 linkages. The structural complexity and abundance of these non-digestible oligosaccharides is unique for human milk as in milk of other mammalian species the level of non-digestible oligosaccharides is much lower. The role of HMOs in human milk is to improve the intestinal microbiota by stimulating bifidobacteria and other beneficial lactic acid producing bacteria and thereby inhibiting the growth of potentially pathogenic bacteria. HMOs furthermore inhibit binding of pathogenic micro-organisms to the infant's epithelial cell surface.

[0007] In the past, infant formulas did not contain non-digestible oligosaccharides. Subsequently infant formulas were developed, containing prebiotic, non-digestible oligosaccharides to functionally mimic the role of the HMOs. One of the best studied mixtures of such prebiotics is a mixture of galacto-oligosaccharides (GOS) plus long chain fructo-oligosaccharides (IcFOS) in a weight ratio of 9:1. Upon administration of this specific prebiotic mixture to infants, bifidobacteria increase and pathogens decrease in the intestinal microbiota, rendering the microbiota more similar to the microbiota of human milk fed infants (Knol et al, Acta Paediatrica, 2005; 94 (Suppl 449); Knol et al, 31-33. Pediatr Gastroenterol Nutr, Vol. 40, No. 1 , January 2005; WO 2005 / 039319). Also, formulas containing probiotics have been developed, as well as formulas comprising both prebiotics and probiotics.

[0008] More recently milk oligosaccharides with a structure identical to HMOs have become available as produced by fermentation by genetically modified micro-organisms and infant formulas containing a HMO or a mixture of HMOs have become available.

[0009] WO 2023 / 118510 describes a nutritional composition comprising a mix of Bifidobacterium species and at least one human milk oligosaccharide, wherein the Bifidobacterium species comprise at least a Bifidobacterium bifidum strain able to express at least one extracellular enzyme selected from a fucosidase and a sialidase, and a Bifidobacterium breve strain able to metabolize a saccharide selected from L-fucose and sialic acid, and the human milk oligosaccharide is at least one selected from the group consisting of 2’-fucosyllactose, 3-fucosyllactose, 3’-sialyllactose, and 6’-sialyllactose.

[0010] This composition is suggested for reducing the risk of occurrence, preventing and / or treating an intestinal infection, intestinal inflammation and / or diarrhea.

[0011] WO 2021 / 116236 discloses age staged nutritional compositions comprising a HMOs mix. Optionally, at least one of the nutritional compositions comprises a prebiotic, preferably the prebiotic comprises polydextrose, galacto-oligosaccharides, or a combination thereof.

[0012] ON 113907144 discloses that certain HMOs can prevent infection by Staphylococcus aureus. A wide array of HMO combinations is suggested including the combination of 2’-fucosyllactose (2’-FL), 3-fucosyllactose (3-FL), lacto-N-tetraose (LNT), 3’-sialyllactose (3’-SL) and 6’-sialyllactose (6’-SL).

[0013] US 2014 / 248415 discloses HMO combinations comprising 2’-FL, LNT, 3’-SL and 6’-SL to be included in infant formula and discloses to optionally include as prebiotic 90% GOS, 10% inulin or FOS. The HMO combination is said to enhance the beneficial effects and efficiency of probiotics.

[0014] US 2023 / 013644 concerns nutritional compositions comprising HMOs for use in providing nutrition to infants at different age stages. Infant formula with the combination of 2’-FL, 3-FL, LNT, 3’-SL, 6’-SL are described. US 2024 / 139222 discloses various combinations of HMOs and for some at least one probiotic strain of the genus Bifidobacterium can be included. The composition would be useful for preventing disease, disorder or condition associated with one or more of inflammation, immune dysfunction, cancer, allergy or dysbiosis. US 2018 / 368460 concerns a synthetic mixture of HMOs essentially consisting of LNnT, LNT, 2'-FL, 3'-SL, 6'-SL and either DFL or 3-FL. Optionally, the composition may also contain a long list of ingredients including probiotics. The composition is for preventing and / or treating viral and / or bacterial infections, specifically modulating the indigenous microbiota and improving cognitive function in non-infant humans.

[0015] US 2012 / 171165 describes a composition comprising a neutral human milk oligosaccharide, preferably 2’FL, and relates to the improvement of the gut barrier function in infants. The document discloses that the activity of alkaline phosphatase is a good indicator of the differentiation of the intestinal epithelium.

[0016] Still there is a need for infant and young child formula with a mixture of non-digestible oligosaccharides that further improves the intestinal microbiota of infants. Nevertheless, there remains a need for nutritional compositions that reduce the risk of developing gastrointestinal infections or gastro-intestinal inflammatory diseases even further.

[0017] SUMMARY OF THE INVENTION

[0018] The inventors of the present invention have surprisingly found that nutritional compositions comprising Bifidobacterium breve and a mixture of five human milk oligosaccharides (HMO), synergistically increases the intestinal alkaline phosphatase levels (iALP), both intracellularly and extracellularly, when compared to the control or the B. breve or HMOS mix alone. iALP is a gut mucosal defense enzyme that is critical for protection of the epithelial barrier. iALP expression and function are lost with starvation and are maintained with enteral feeding. iALP has the capacity to detoxify bacterial endotoxin lipopolysaccharide (LPS) and can prevent translocation of active LPS and bacterial invasion across the gut epithelial barrier. Higher expression of iALP is therefore a marker for a stronger gut epithelial defence and / or gut barrier function, which results in a lower risk of developing gastrointestinal infections or gastro-intestinal inflammatory diseases.

[0019] Hence a first aspect of the invention pertains to a nutritional composition, not being human milk, comprising digestible carbohydrate, protein, lipid, a mixture of the human milk oligosaccharides (HMO) 2’-fucosyllactose, 3-fucosyllactose, 3’-sialyllactose, 6’-sialyllactose and lacto-N-tetraose, and Bifidobacterium breve for use in one or more of: i) strengthening the gut epithelial defence; ii) strengthening the gut barrier function; iii) preventing intestinal inflammatory diseases; and iv) preventing intestinal infections.

[0020] A second aspect of the invention relates to a nutritional composition, not being human milk, comprising digestible carbohydrate, protein, lipid, 0.3 to 4 wt% based on dry weight of a mixture of the human milk oligosaccharides (HMO) 2’-fucosyllactose, 3-fucosyllactose, 3’-sialyllactose, 6’-sialyllactose and lacto-N- tetraose, and 105to 1012colony forming units (cfu) Bifidobacterium breve.

[0021] DETAILED DESCRIPTION OF THE INVENTION

[0022] In particular the present invention concerns a method for: i) strengthening the gut epithelial defence; ii) strengthening the gut barrier function; iii) preventing intestinal inflammatory diseases; and iv) preventing intestinal infections comprising administration of a nutritional composition comprising digestible carbohydrate, protein, lipid, Bifidobacterium and human milk oligosaccharides (HMOs), to a subject in need thereof, wherein a) the HMOs are a mixture of 2’-fucosyllactose, 3-fucosyllactose, 3’-sialyllactose, 6’-sialyllactose and lacto-N-tetraose, and b) the Bifidobacterium comprises Bifidobacterium breve. For some jurisdictions the invention can be worded as a nutritional composition comprising digestible carbohydrate, protein, lipid, Bifidobacterium and human milk oligosaccharides (HMOs), wherein a) the HMOs are a mixture of 2’-fucosyllactose, 3-fucosyllactose, 3’-sialyllactose, 6’-sialyllactose and lacto-N-tetraose, and b) the Bifidobacterium comprises Bifidobacterium breve, for use in one or more of: i. preventing intestinal inflammatory diseases, and ii. preventing intestinal infections, wherein said nutritional composition is not human milk.

[0023] For some jurisdictions the invention can be worded as the use of digestible carbohydrate, protein, lipid Bifidobacterium and human milk oligosaccharides (HMOs), for the manufacture of a nutritional composition, wherein a) the HMOs are a mixture of 2’-fucosyllactose, 3-fucosyllactose, 3’-sialyllactose, 6’-sialyllactose and lacto-N-tetraose, and b) the Bifidobacterium comprises Bifidobacterium breve, for use in one or more of: i. preventing intestinal inflammatory diseases, and ii. preventing intestinal infections,

[0024] In particular with regard to i) strengthening the gut epithelial defence; and ii) strengthening the gut barrier function, the present method can be seen as a non-therapeutic method.

[0025] The invention thus can also be worded as a non-therapeutic use of a nutritional composition comprising digestible carbohydrate, protein, lipid, Bifidobacterium and human milk oligosaccharides (HMOs), wherein a) the HMOs are a mixture of 2’-fucosyllactose, 3-fucosyllactose, 3’-sialyllactose, 6’-sialyllactose and lacto-N-tetraose, and b) the Bifidobacterium comprises Bifidobacterium breve, for one or more of i) strengthening the gut epithelial defence; and ii) strengthening the gut barrier function, wherein said nutritional composition is not human milk.

[0026] In another aspect the invention concerns a nutritional composition, which is not human milk, comprising digestible carbohydrate, protein, lipid, Bifidobacterium breve and human milk oligosaccharides (HMO), wherein a. the HMOS are present in an amount of 0.3 to 4 wt% based on dry weight, b. the HMOS are a mixture of 2’-fucosyllactose, 3-fucosyllactose, 3’-sialyllactose, 6’-sialyllactose and lacto-N-tetraose, and c. the Bifidobacterium breve is present is an amount of 105to 1012colony forming units (cfu) per gram of dry weight of the composition.

[0027] In yet even another preferred embodiment, administering a nutritional composition to an infant may be considered non-therapeutic. In those instances, the invention may be worded as defined above by way of a method comprising administering a nutritional composition. For clarity, the method can also be defined as a non-therapeutic method. By definition, the words “non-therapeutic” exclude any therapeutic effect.

[0028] Preferably, the use of the present invention is by increasing the intracellular expressed activity of intestinal alkaline phosphatase (iALP) and / or by increasing the extracellular secreted iALP activity.

[0029] In a preferred embodiment, the prevention of intestinal inflammatory diseases and / or intestinal infections is by strengthening the gut epithelial defence and / or the gut barrier function.

[0030] Preferably, the intestinal inflammatory diseases are selected from enterocolitis, necrotizing enterocolitis (NEC) and inflammatory bowel diseases. Examples of inflammatory bowel diseases are Crohn’s disease and ulcerative colitis.

[0031] Preferably, the intestinal infections are infections caused by bacteria, viruses, fungi or parasites. More preferably, the intestinal infections are infections caused by bacteria or viruses. Most preferably, the intestinal infections are bacterial infections.

[0032] Preferably, the use of the present invention is in a human subject, more preferably in a human young child of 1 , 2 or 3 years of age, or an infant of 0 up to 12 months of age, more preferably in a human young child of 1 or 2 years of age, or an infant of 0 up to 12 months of age, even more preferably an infant 0-12 months and most preferably an infant of 0-6 months.

[0033] Levels of iALP are lower in preterm infants. Preterm infants are infants born before the 37thweek of gestational age. Therefore, the nutritional composition is advantageously for use in these infants born premature.

[0034] Allergic infants or allergic young children may benefit from the composition as a strengthened gut barrier function will result in less allergens crossing the intestinal barrier. Therefore, the nutritional composition is advantageously for use in infants or young children that are allergic to food proteins, in particular cow’s milk protein. Subjects with microbial dysbiosis, such as caused by antibiotic treatment or being born by C-section are known to have lowered levels of iALP. Hence, the nutritional composition is advantageously for use in infants or young children that were born via C-section and / or treated with antibiotics.

[0035] In an alternative embodiment, the use of the present invention is in an adult human subject.

[0072] The lipid provides preferably 30 to 60% of the total calories of the nutritional composition. More preferably the nutritional composition comprises lipid providing 35 to 55% of the total calories, even more preferably the nutritional composition comprises lipid providing 40 to 50% ofthe total calories. The lipids are preferably present in an amount of 4 to 6 g per 100 kcal.

[0076] Fatty acid composition

[0077] SFA relates to saturated fatty acids and / or acyl chains, MUFA relates to mono-unsaturated fatty acid and / or acyl chains, PUFA refers to polyunsaturated fatty acids and / or acyl chains with 2 or more unsaturated bonds; LC-PUFA refers to long chain polyunsaturated fatty acids and / or acyl chains comprising at least 20 carbon atoms in the fatty acyl chain and with 2 or more unsaturated bonds; DHA refers to docosahexaenoic acid and / or acyl chain (22:6, n3); EPA refers to eicosapentaenoic acid and / or acyl chain (20:5 n3); ARA refers to arachidonic acid and / or acyl chain (20:4 n6); DPA refers to docosapentaenoic acid and / or acyl chain (22:5 n3). n3 or omega 3 PUFA refers to polyunsaturated fatty acids and / or acyl chains with 2 or more unsaturated bonds and with an unsaturated bond at the third carbon atom from the methyl end of the fatty acyl chain, n6 or omega 6 PUFA refers to polyunsaturated fatty acids and / or acyl chains with 2 or more unsaturated bonds and with an unsaturated bond at the sixth carbon atom from the methyl end of the fatty acyl chain.

[0078] The nutritional composition preferably comprises LA, which refers to linoleic acid and / or acyl chain (18:2 n6). LA is an n6 PUFA and the precursor of n6 LC-PUFA and is an essential fatty acid as it cannot be synthesized by the human body.

[0099] EXAMPLES

[0100] Example 1

[0101] An in vitro study was conducted to investigate the effect of B. breve and HMOS in an infant formula matrix on the production of intestinal alkaline phosphatase (iALP) by intestinal cells, both intracellularly expressed and extracellular secreted iALP.

[0102] Infant formulas

[0103] Two different types of powdered IF’s were tested in these examples. Both were complete standard cow’s milk-based infant formulas having a similar composition, except for the presence of Bifidobacterium breve and / or human milk oligosaccharides.

[0104] The IF’s comprised per 100 ml reconstituted formula, 13.6 dry matter, 66 kcal, 1 .3 g protein (intact protein with a casein / whey ratio of 40 / 60), 7.3 g digestible carbohydrates (mainly lactose), 3.4 g fat and 0.8 g short chain galacto-oligosaccharides (source Vivinal® GOS) and long chain fructo-oligosaccharides (source Raftilin HP®) in a 9 / 1 w / w ratio, and minerals, vitamins, trace elements and other micronutrients as known in the art and in compliance with directives for infant formula. The fatty acid composition was identical for all IF’s. The fat source of all IF’s comprised vegetable fat, milk lipid, and LC-PUFA containing oil (fish oil and microbial oil).

[0105] IFA is a composition without HMO and without probiotic bacteria.

[0106] IFB is a composition that comprises 1 .4 wt% HMOS based on dry weight. The HMO blend comprised five types of HMO, said five types of HMO being 2’-FL, 3-FL, LNT, 3’-SL, and 6’-SL in a wt.%, by weight of total HMO weight, of 52%, 13%, 26%, 4% and 5%, respectively (mix Chr. Hansen). In addition, it comprises 1 .108cfu per g dry weight of the probiotic bacterium Bifidobacterium breve M16-V strain (Morinaga).

[0107] In vitro digestion of IPs

[0108] The different IFs and a control PBS sample were digested in vitro using an in vitro digestion model (SIM) based on the INFOGEST model (Menard et al., Food chemistry, vol. 240, 2018, 338-345). The different IF’s comprised per 100 ml reconstituted formula 13.6 grams powdered IF product.

[0109] The bioreactor comprised at the start of the digestion experiment 35 mL of IF to simulate the ingestion of a 200 mL meal by a 0-6 month-old infant. All other volumes were adjusted proportionally to this volume. The ratio between infant formula to simulated digestive fluids (and the composition thereof) resembled recommendations for digestion model from INFOGEST. The temperature of the bioreactor was set to 37 °C using a water bath.

[0110] After the IF reached a temperature of 37 °C, a single shot of simulated saliva fluid (SSF) and simulated gastric fluid (SGF) was added to the bioreactor in order to start the simulation of the gastric phase. The gastric phase lasted 120 minutes during which SGF was continuously added and the pH was gradually lowered following a set curve based on in vitro observations by the addition of 0.25 mL HCI to closely mimic the postprandial infant gastric pH.

[0111] After the gastric phase, the pH was increased to 6.5 in 10 minutes by the addition of 1 M NaHCOs to prepare for the simulation of the subsequent intestinal phase. The intestinal phase lasted 180 minutes and was started by a single shot of simulated intestinal fluid (SIF). During the intestinal phase SIF was continuously added and the pH was gradually increased to 7.2 over the course of 180 minutes by the addition of a solution comprising 0.25 M NaHCOs and 0.25 M NaOH. Digesta samples (2 ml) was taken from the bioreactor after 1 hour into the intestinal phase. The samples were visually homogenous, indicating that the samples were representative of the conditions in the bioreactor as a whole. The digesta samples were immediately quenched after collection with 2 ml of sample buffer containing enzyme inhibitor cocktail Pefabloc and Orlistat. After the digesta samples were quenched, the samples were snap frozen using liquid nitrogen.

[0112] Cell Culture

[0113] A human Caco-2 cell line was used as a model of intestinal epithelium and purchased from ATCC (HTB- 37). Cells (passages 50-70) were maintained in a complete growth medium DMEM (high glucose+ Glutamax, phenol red, 31966021 , Gibco) supplemented with 10% heat-inactivated fetal bovine serum (10270106, Gibco), 1 % penicillin-streptomycin (15140-130, Gibco), 1% non-essential amino acids in MEM (MEM NEAA 100X, 11140-035, Gibco), 1% sodium pyruvate in MEM (100 mM stock, 11360-039, Gibco). The cells were grown in 75 cm2flasks (Nunc EasyFlask, Thermo scientific) in a humid incubator (HeraCell 150, Thermo Scientific) at 37 °C and 5% CO2, and were routinely subcultured after being confluent at 80%, with a change of medium thrice a week after 100% confluence. Cell viability and concentration was measured each week using an automated cell viability analyzer (Vi-Cell XR, Beckman Coulter).

[0114] Alkaline phosphatase assay

[0115] Caco-2 cells were seeded at 2.5 x 105cells / mL in 24-well plates (3526, Corning COSTAR®, Corning Inc.) and kept in culture for 16 days, with a change of medium thrice a week.

[0116] The digesta samples (of the IF-products and the PBS control) from the in vitro digestion were further diluted in a 1 :32 ratio with culture medium (high glucose+ Glutamax, phenol red, 31966021 , Gibco) supplemented with 1 % BSA, 1% penicillin-streptomycin (15140-130, Gibco), 1 % sodium pyruvate in MEM (100 mM stock, 11360-039, Gibco) prior to addition to the cells which received fresh culture medium just before (final dilution 1 :64). Each condition was tested in triplicate.

[0117] Caco-2 cells were incubated with the diluted digesta samples for 4 days, and 20 uL supernatant of each well was collected on each day - day zero (DO) to day 4 (D4) - and tested for secreted alkaline phosphatase activity (Abeam ab83369). After 4 days, cells were lyzed and expressed intracellular iALP levels were measured. In each of the collected samples also the total protein was measured (Pierce BCA Protein Assay kit, Thermo Scientific). The iALP enzyme units were standardized per gram of protein.

[0118] Results

[0119] The results are depicted in Figure 1 . The iALP activity on the y-axis is shown as a fold-change to the iALP activity of the PBS control sample on DO. The statistically significant differences are indicated in Figure 1 by the horizontal lines above the bars (ANOVA followed by a Least Significant Difference (LSD) test for conditions comparisons (p<0.05)). The combination of B. breve and HMOs induces a higher expression of iALP when compared to the control.

[0120] Example 2

[0121] The experiment from Example 1 was repeated, but this time four different IFs were compared, to distinguish the effect between HMOS and B. breve:

[0122] The amount of B. breve and HMOS, when present, was the same as in example 1. The HMO blend comprised five types of HMO, said five types of HMO being 2’-FL, 3-FL, LNT, 3’-SL, and 6’-SL in a wt.%, by weight of total HMO weight, of 52 wt.%, 13 wt.%, 26 wt.%, 4 wt.% and 5 wt.%, respectively (mix Chr. Hansen). The probiotic Bifidobacterium breve strain was B. breve M16-V (Morinaga), and was present in an amount of 1 .108cfu per g dry weight.

[0123] All other components of the four IF were similar, like in example 1. The IF’s comprised per 100 ml reconstituted formula, 13.6 dry matter, 66 kcal, 1.3 g protein (intact protein with a casein / whey ratio of 40 / 60), 7.3 g digestible carbohydrates (mainly lactose), 3.4 g fat and 0.8 g short chain galactooligosaccharides (source Vivinal® GOS) and long chain fructo-oligosaccharides (source Raftilin HP®) in a 9 / 1 w / w ratio, and minerals, vitamins, trace elements and other micronutrients as known in the art and in compliance with directives for infant formula. The fatty acid composition was identical for all IF’s. The fat source of all IF’s was identical and comprised vegetable fat, milk lipid, and LC-PUFA containing oil (fish oil and microbial oil).

[0124] Results

[0125] The results are depicted in Figure 2 (secreted extracellular iALP on day 4) and Figure 3 (intracellular expressed iALP on day 4) - with on the x-axis the PBS control sample (control) and the different IF’s. The SEM is shown for each condition. For the intracellular expressed iALP the iALP activity on the y-axis is shown in enzyme units standardized per gram of protein. For the extracellularly secreted iALP the iALP activity on the y-axis is shown as a fold-change to the iALP activity of the PBS control sample on DO. The statistically significant differences are indicated in Figure 2 and 3 by the star. The iALP activity, both intracellularly and extracellularly, was similar for control, IF-1 , IF-2 and IF-3. Only I F-4 showed a higher iALP activity, which was significantly different from each of the other tested conditions (ANOVA followed by a Least Significant Difference (LSD) test for conditions comparisons (p<0.05)).

[0126] The combination of B. breve and HMO when present in a nutritional composition synergistically increases the intracellular expression of iALP and the secretion of iALP. The increase of expression and secretion of iALP is indicative of enforcement of gut epithelial defence and strengthening of the gut barrier and therefore contributes towards preventing intestinal inflammatory diseases and intestinal infections.
