Abstract
The present invention relates to a nutraceutical composition comprising inulin and a Chilean wineberry extract, and also other ingredients such as amino acids, vitamins and/or trace elements, in particular for the use thereof in preventing and/or treating ocular pathological conditions and/or in preventing and/or treating intestinal microbiota imbalances.
Description
FIELD OF THE INVENTION

The present invention relates to a nutraceutical composition comprising inulin and a Chilean wineberry extract, and also other ingredients such as amino acids, vitamins and/or trace elements, in particular for the use thereof in preventing and/or treating ocular pathological conditions and/or in preventing and/or treating intestinal microbiota imbalances.


STATE OF THE ART

Ocular pathological conditions include many eye conditions that are often accompanied by discomfort. These different disorders can occur in various forms such as stinging, itching, a burning sensation, sand or foreign body sensations in the eyes, or sensitivity to light, visual disturbance, fatigue or ocular pain, or headaches, but they can also result from tear film instability, inflammation of corneal cells, or inflammation of goblet cells in the eyes.


These symptoms may also be associated with other diseases such as ocular dryness syndrome, meibomian gland dysfunction, allergic conjunctivitis, keratoconjunctivitis, or blepharoconjunctivitis. Finally, this discomfort can be the result of surgery.


Studies have shown that there is a relationship between the microbiota and eye diseases (Baim and al. Experimental Biology and Medicine, 2019, 244, 419-429), and that the administration of prebiotics can reduce eye disorders (Flanagan and al., Antibiotics, 2019, 8, 1-23).


Prebiotics, dietary compounds in the form of sugars such as oligosaccharides and polysaccharides with short carbon chains are essential for the development and growth of bacteria in the intestinal flora. The breakdown products of prebiotics are released into the circulation and act on various organs which may be distant from each other.


One of the well-known prebiotics is inulin. This soluble fiber composed of fructose molecules is widely used as an ingredient and/or as an active compound in the food industry, for example as a supplement in infant milk powders to promote the growth of newborns with other supplements such as polyunsaturated fatty acids (Gold Mamil Growing Up Formula Step 3 from Mintel) but also in the pharmaceutical field (Hinrichs and al., Carbohydrate Polymers, 2015, 134, 418-428) and in particular for the prevention and treatment of allergies in children (WO 2013/062402), for the treatment of inflammation in combination with xylans (WO 2011/020853) or for the prevention or treatment of pathological conditions associated with the lifestyle of people (JP 201317441). Mixtures of plants, including roots known to contain inulin are also described for treatments derived from traditional Chinese medicine (CN 1245187).


Numerous pharmaceutical and nutraceutical compositions exist for the treatment of ocular diseases. However, although these compositions can act on ocular disorders, they do not allow to treat all the associated symptoms, and in particular have no action on the inflammation responsible for the discomfort.


The inventors have therefore developed a nutraceutical composition based on inulin having beneficial effects on the entire system in the case of ocular pathological conditions.


In particular, the inventors have developed a nutraceutical composition based on inulin and Chilean wineberry extract, having beneficial effects on the intestinal microbiota of people, in particular on its metabolic activity and/or on the membrane permeability of the intestines for the molecules involved in the phenomena of inflammation and/or on the composition of the microbiota, its diversity and its balance in certain microbial groups, good health.


The composition can be used preventively and/or in the context of a treatment.


DISCLOSURE OF THE INVENTION

According to another embodiment, the invention relates to a formulation adapted for oral administration comprising inulin, a Chilean wineberry extract, one or more amino acids, preferably including carnitine, vitamins and minerals.


According to another embodiment, the present invention relates to a nutraceutical composition comprising inulin and a Chilean wineberry extract comprising anthocyanidins preventing and/or treating ocular pathological conditions.


According to another embodiment, the present relates to a nutraceutical composition comprising inulin and a Chilean wineberry extract comprising anthocyanidins preventing and/or treating an imbalance of the intestinal microbiota and of the pathological conditions associated with this imbalance.







DETAILED DESCRIPTION OF THE INVENTION
Definitions

The term “nutraceutical” refers to an edible product having a physiological beneficial effect. Thus, nutraceutical composition means a composition whose purpose is to supplement the normal diet and constituting a concentrated source of nutrients or other substances having a nutritional or physiological effect, alone or in combination.


The term “ocular pathological conditions” includes various diseases affecting the eyes. In some cases, they result in simple ocular discomfort, but can sometimes become disabling. “Ocular pathological conditions” thus means stinging, itching, burning sensations, sand or foreign body sensations in the eyes, sensitivity to light, visual disturbance, ocular fatigue, ocular pain, tear film instability, inflammation of corneal cells, inflammation of goblet cells in the eyes and/or headache. The ocular pathological conditions can also be chosen from ocular dryness syndrome, meibomian dysfunction, allergic conjunctivitis, keratoconjunctivitis, blepharoconjunctivitis, and/or be associated with eye surgery.


“Intestinal microbiota imbalance” means an imbalance in the activity of the microbial community and/or an imbalance in the microbial composition and/or an increase in the intestinal membrane permeability.


The “microbial community” is made up of all the microorganisms that make up the intestinal microbiota of an individual. Its composition, the diversity of the microbial groups present or the relative abundance of certain microbial groups are markers of an imbalance that impacts the state of health of an individual and in particular his sensitivity or his propensity to develop ocular pathological conditions. High diversity is a sign of good intestinal health.


An improvement of an imbalance of the activity of the microbial community will be observed in particular on the capacity of this community to release short-chain fatty acid, on the modulation of the concentration of lactate, on the pH, on the reduction of the amount of ammonium released and/or on gas production.


Short-chain fatty acids (acetate, propionate, butyrate, isobutyrate, isovalerate and isocaproate) are derived from the intestinal bacterial fermentation of indigestible foods, and are the main source of energy for colon cells, making them essential for gastrointestinal health.


The intestine is home to both lactate-producing bacteria and bacteria that use it. Lactate is produced by lactic acid bacteria and lowers the pH of the environment, also acting as an antimicrobial agent. Lactate can also be rapidly converted into acetate, butyrate and propionate by other microorganisms.


The measurement of pH and the degree of acidification is a measurement of the intensity of bacterial metabolism.


Ammonium is a proteolytic degradation product that results in the production of potentially toxic or carcinogenic compounds such as p-cresol and p-phenol.


Excess gas production is considered a potentially negative effect of increased saccharolytic activity of the intestinal community.


The increase in membrane permeability will result from an imbalance in the composition of the intestinal microbiota (dysbiosis) and leads to an increase in inflammation of the digestive system and to a general inflammatory state which will promote the development of pathological conditions associated with the inflammation and in particular ocular pathological conditions.


The improvement in membrane permeability is the consequence of an improvement in the composition of the intestinal microbiota which, in particular, promotes the prevention and/or treatment of ocular pathological conditions.


Other markers of intestinal microbiota imbalance are the inflammation markers pro-inflammatory cytokines (human IL-1β, IL-6, IL-8, TNF-α, CXCL10 and MCP-1) as well as the (pro-inflammatory) NF-κB activity.


A decrease in the production of these markers by the membrane epithelial cells of the intestine is the consequence of an improvement in the composition of the intestinal microbiota which, in particular, promotes the prevention and/or treatment of ocular pathological conditions.


The improvement in the imbalance of the intestinal microbiota can be quantified by the production of IL-10 (anti-inflammatory). An increase in the production of IL-10 is the consequence of an improvement in the composition of the intestinal microbiota which, in particular, promotes the prevention and/or treatment of ocular pathological conditions.


Nutraceutical Composition


The composition comprises prebiotics, natural fibers present in many plants such as fruits, vegetables, cereals and legumes, and more particularly inulins.


Inulins or inulin (CAS [9005-80-5]), are soluble dietary fibers consisting of fructose units with a terminal glucose. These natural or synthetic polysaccharides have an average degree of polymerization comprised between 2 and 60. Inulin is naturally present in many plants, such as artichokes, asparagus, bananas, leeks, Jerusalem artichokes, onions, tomatoes, barley and rye or else chicory roots, dandelion roots, and elecampane roots.


In the context of the present invention, the inulin is of natural origin, and preferentially extracted from chicory roots, dandelions and Jerusalem artichokes. In a preferred embodiment, inulin is extracted from the chicory root.


The inulin is present in an amount comprised between 1 000 and 10 000 mg, preferably between 2 000 and 8 000 mg. In one embodiment, the amount of inulin is 3 000 to 7 000 mg, preferably 4 000 to 6 000 mg, even more preferably 4 500 to 5 500 mg. In a preferred embodiment, the amount of inulin is about 5 000 mg.


In another embodiment, the inulin represents at least 50% by weight of the total composition, preferably at least 60%, and more preferably at least 70%.

In a preferred embodiment, the composition comprises about 87% inulin by weight.


The composition additionally comprises a Chilean wineberry extract. This exotic fruit, also known as Aristotelia chilensis, has been used for several years in the pharmaceutical field. Several studies have shown that this natural antioxidant rich in anthocyanins and anthocyanidins has beneficial effects on the body. It can thus be used for example for the treatment of diabetes and metabolic syndrome (WO 2009/059218).


The molecules of interest present in Chilean wineberry are in particular anthocyanidins, also called anthocyanidins. In hydroxylated form, these compounds belonging to the subclass of flavonoids, exist mainly in 6 forms: cyanidol, delphinidol, pelargonidol, malvidol, peonidol and petunidol. Among these different forms, delphinidol or delphinidin is an organic compound present in many plants with strong natural antioxidant activity.


In the context of the present invention, the nutraceutical composition comprises, in addition to inulin, anthocyanidins from the Chilean wineberry. Chilean wineberry extracts are known and used pure or in high concentrations in in vitro studies (“Maqui berry extract”, from the company Oryza Oil & Fat Chemical Co.) or as active ingredients in pharmaceutical compositions or food supplements (ES 2685324; “Double Chocolate All-in-One Nutrition Bar” from the company Mintel).

EXAMPLES
Example 1

A nutraceutical composition is formulated as a powder to be diluted in a large glass of water and comprises 5 000 mg of inulin, 60 mg of Chilean wineberry extract, 298 mg of L-carnitine tartrate, 1.76 mg of riboflavin (vitamin B2), 56 mg of zinc bisglycinate, and 5 mg of cholecalciferol (vitamin D3).


Patients with ocular pathological conditions (stinging, itching, burning sensations, foreign body sensations, sensitivity to light, visual disturbance, eye fatigue, ocular pain, tear film instability, inflammation of corneal cells, inflammation of goblet cells in the eyes and/or headaches) are selected to follow a treatment with the nutraceutical composition for at least 30 days at the rate of one intake per day.


The patients are questioned before and after taking the nutraceutical composition, at regular intervals, to monitor their response to the treatment, the evolution of their pathological condition and any side effects.


A beneficial effect is observed for the majority of patients.


Example 2

The effect of the composition of example 1 on the intestinal microbiota is analyzed in vitro on microbiota samples from healthy individuals. The collected cells are suspended in an appropriate medium for their conservation. 4 samples are made (1) control, (2) with addition of inulin, (3) with addition of a Chilean wineberry extract and (4) with addition of the composition of example 1.


Microbial community composition and activity analyzes are carried out and show improvement for the sample (4).


Example 3

Analyzes of membrane permeability of the intestinal epithelial cells associated with immune parameters are carried out, (1) control without other addition, (2) with addition of inulin, (3) with addition of a Chilean wineberry extract and (4) with addition of the composition of Example 1.


Membrane permeability is measured using transepithelial electrical resistance in an in vitro model of intestinal microbiota imbalance. A drop in transepithelial electrical resistance is an indication of disruption of the intestinal epithelial cell monolayer. If the product to be tested avoids this drop, then it is capable of protecting the cells of the intestinal epithelium against hyperpermeability related to dysbiosis.


The immune parameters are measured by the production of pro-inflammatory cytokines (human IL-1β, IL-6, IL-8, TNF-α, CXCL10 and MCP-1) as well as the (pro-inflammatory) NF-κB activity. The production of (anti-inflammatory) IL10 will also be measured.


An improvement is observed for the composition of example 1.
