Definitions

  • the present invention relates to a composition for a medical device comprising a specific mucoadherent gelling complex composed of EPS, exopolysaccharides of bacterial origin produced in situ in the gastrointestinal tract by specific selected bacterial strains, in association with vegetable gums and/or animal and/or vegetable gelatines.
  • Said complex is capable of establishing a complete barrier effect of a mechanical type extending throughout the whole gastrointestinal tract and can be used as a medication for the prevention and treatment of all pathologies connected to a deficiency in the barrier effect in the gastrointestinal area due to a low production of mucus, such as, by way of non-exhaustive example, intestinal permeability and bacterial translocation.
  • bacteria in general such as, for example, bacteria belonging to the species Streptococcus thermophilus, are sensitive to gastric juices and arrive in the gastrointestinal tract in reduced concentrations and with little vitality.
  • bacterial strains such as, for example, bacteria belonging to the species Streptococcus thermophilus, which are already present in the bacterial flora of the intestine or are carried in the intestine.

  • Said at least one bacterial strain is selected preferably from the group comprising or, alternatively, consisting of probiotic bacterial strains belonging to the species Streptococcus thermophilus, Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus pentosus, Lactobacillus acidophilus, Lactobacillus brevis, Lactobacillus reuteri, Bifidobacterium breve, Bifidobacterium bifidum, Bidifobacterium lactis, Lactobacillus fermentum and Lactobacillus delbrueeckii.
  • Said at least one bacterial strain is selected from the group comprising or, alternatively, consisting of probiotic bacterial strains belonging to the species Streptococcus thermophilus, Lactobacillus plantarum or Lactobacillus rhamnosus.
  • Said probiotic bacterial strains must be EPS producers in situ in the gastrointestinal tract.

  • a gum is a dehydrated or lyophilized or dried material in the form of a powder or flakes which on coming into contact with water produces a gum gel in water (aqueous gel) or a gum gelatine.
  • aqueous gel aqueous gel
  • a gum gelatine a gum gelatine
  • an already prepared gel or gelatine can be validly used.
  • the gums used are all gums for oral use which are allowed and used in food supplements and medical devices.
  • the vegetable gum and/or the animal and/or vegetable gelatine is selected from the group comprising or, alternatively, consisting of Aloe, Aloe vera (Aloe vera -Aloe barbadensis Miller, is a plant of the Aloaceae family), Aloe arborescens, alginates, xyloglucans (or xylogels), tannates, gelatine tannate, carrageenans, pectins, agar-agar and tara gum.
  • the vegetable gum and/or the animal and/or vegetable gelatine is selected from the group comprising or, alternatively, consisting of Aloe arborescens, gelatine tannate and tara gum.
  • gelatine tannate a complex of gelatine and tannic acid
  • Gelatine tannate forms a mucoadhesive protective film of protein origin which protects the intestinal mucosa.
  • a vegetable gum and/or an animal or vegetable gelatine undergoes a slow but inexorable degradation as it passes from the stomach to the intestine. The gum degrades and loses its effectiveness in restoring the physiological functions of the intestinal walls.
  • This degradation is due to multiple factors, such as, for example pH, enzymes, attacks from endogenous bacterial flora, the effect of the gastroduodenal barrier and a dilution effect. Practically speaking, there is a loss of effectiveness that occurs progressively as the gelatine tannate passes through the gastrointestinal tract, also as the result of an attack by acid, bile salts, pancreatic juices and enzymes. When the gelatine tannate arrives in the colon it is in part degraded and thus less effective in protecting the walls of the intestine against pathogenic bacteria, which are able to penetrate it by means of their flagella.
  • gum of bacterial origin produced in situ by the strains of the present invention selected from the group comprising or, alternatively, consisting of probiotic bacterial strains belonging to the species Streptococcus thermophilus, Lactobacillus plantarum or Lactobacillus rhamnosus, on the one hand, and a vegetable gum and/or an animal and/or vegetable gelatine, on the other hand, each have an effect of their own and they are complementary to each other.
  • the first effect is a gelling effect exerted by the vegetable gum and/or the animal and/or vegetable gelatine, and which is maximum in the stomach (maximum protection) and minimum in the colon due to the degradation and consequent loss of effectiveness in protecting inflamed intestinal mucosae.
  • the second effect is a protective effect exerted by the gum of bacterial origin, in particular by exopolysaccharides (EPS) produced in situ by the strains of the present invention selected from the group comprising or, alternatively, consisting of probiotic bacterial strains belonging to the species Streptococcus ihermophilus, Lactobacillus plantarum or Lactobacillus rhamnosus.
  • EPS exopolysaccharides
  • compositions or a medical device for use as a medication for the prevention and the treatment of all pathologies connected to a deficiency in the barrier effect in the gastrointestinal area due to a low production of mucus.
  • compositions of the present invention are capable of restoring the barrier effect that was lost because of insufficient protection of the mucosa in the gastrointestinal tract.
  • compositions of the present invention are capable of preventing and treating infections, inflammations and disorders of the gastrointestinal tract, pathogenic bacteria, candidiasis and intestinal permeability.
  • composition of the present invention is capable of forming a specific mucoadherent gelling complex, composed of EPS, exopolysaccharides of bacterial origin (produced by selected strains as specified below, belonging in particular to the species Streptococcus thermophilus, e.g. Streptococcus ihermophilus ST10 -DSM 25246, Streptococcus thermophilus (Y04) DSM 16592 or mixtures thereof in a ratio by weight comprised from 1 :2 to 2:1 , preferably 1 :1 , and tara gum, a polysaccharide of vegetable origin.
  • Said gelling complex is capable of establishing a barrier effect of a mechanical type extending throughout the whole gastrointestinal tract.
  • the composition of the present invention is capable of forming a hydrogel within few minutes after ingestion, by virtue of its thixotropic characteristics, and of thereby creating, in the first part of the gastrointestinal tract, a barrier effect of a mechanical type against pathogenic bacteria and metabolites with pro-inflammatory action.
  • This barrier effect is completed and extended for the entire length of the gastrointestinal tract by the presence of exopolysaccharides (EPS), produced in situ by probiotic bacterial strains belonging to the species Streptococcus thermophilus, as specified below, e.g.
  • EPS exopolysaccharides
  • Sfrepfococcus thermophilus ST10 Streptococcus thermophilus YO04 or mixtures thereof, which serve to increase the viscosity of the surrounding environment through an exclusively mechanical, self-regulated mechanism.
  • the intake of the aforesaid bacteria conveys into the human intestine a source of molecules with a gelling activity, thus exerting an action which is totally complementary to that of tara gum.
  • the above-mentioned mucoadherent gelling complex has an innovative property to be taken into consideration: during its intestinal transit, tara gum (like all gums of vegetable origin) is progressively degraded by the resident microbiota, so that its mechanically opposing gelling power is progressively reduced.
  • the presence, production and retention of the hydrophilic gel in the lumen of the organ can therefore for the first time be considered really complete, with a first area in which the action of the vegetable gum is maximum and a second area in which the action of the exopoiysaccharides (EPS) is maximum.

Description

COMPOSITIONS FOR A MEDICAL DEVICE COMPRISING
EXOPOLYSACCHARIDE-PRODUCING BACTERIAL STRAINS IN ASSOCIATION WITH GUMS AND/OR GELATINES
The present invention relates to a composition for a medical device comprising a specific mucoadherent gelling complex composed of EPS, exopolysaccharides of bacterial origin produced in situ in the gastrointestinal tract by specific selected bacterial strains, in association with vegetable gums and/or animal and/or vegetable gelatines. Said complex is capable of establishing a complete barrier effect of a mechanical type extending throughout the whole gastrointestinal tract and can be used as a medication for the prevention and treatment of all pathologies connected to a deficiency in the barrier effect in the gastrointestinal area due to a low production of mucus, such as, by way of non-exhaustive example, intestinal permeability and bacterial translocation.
It is known that bacteria in general, such as, for example, bacteria belonging to the species Streptococcus thermophilus, are sensitive to gastric juices and arrive in the gastrointestinal tract in reduced concentrations and with little vitality.
Furthermore, it is known that pathogenic bacteria attack and penetrate the intestinal mucosa more easily when the intestinal mucosa is inflamed or when little mucus is present on the intestinal wall.
There thus remains a need to be able to preserve, in sufficient number and in a good state of vitality, bacterial strains, such as, for example, bacteria belonging to the species Streptococcus thermophilus, which are already present in the bacterial flora of the intestine or are carried in the intestine. Moreover, there remains a need to preserve the intestinal mucosa in such a way as to avoid, reduce or at least oppose the action of pathogenic bacteria.
The subject matter of the present invention relates to a composition for a medical device having features as defined in the appended independent claim.
Preferred embodiments of the present invention will appear more clearly from the detailed description that follows and are claimed in the appended claims.
The Applicant has found it useful to develop a composition or a medical device (composition for a medical device) comprising or, alternatively, consisting of gums of bacterial origin, in particular exopolysaccharides (EPS), in association with vegetable gums and/or animal and/or vegetable gelatines, said gums of bacterial origin being produced by said bacteria in situ in the gastrointestinal tract in the presence of said vegetable gums and/or animal and/or vegetable gelatines. Said bacterial gum produced directly by the probiotic bacterial strains of the present invention together with the vegetable gums and/or the animal and/or vegetable gelatines, are capable of preserving and protecting the intestinal mucosa in such a way as to avoid, reduce or at least oppose the action of pathogenic bacteria which are deleterious for the mucosa itself.
In particular, the present invention relates to a composition or a medical device (composition for a medical device) comprising or, alternatively, consisting of gums of bacterial origin, in particular exopolysaccharides, produced by said bacteria in situ in the gastrointestinal tract in association with vegetable gums and/or animal and/or vegetable gelatines.
The Applicant has found a way to form a specific mucoadherent gelling complex, which is composed of EPS, exopolysaccharides of bacterial origin produced in situ in the gastrointestinal tract by specific selected bacterial strains, in association with vegetable gums and/or animal and/or vegetable gelatines.
The subject matter of the present invention relates to a specific mucoadherent gelling complex composed of EPS, exopolysaccharides of bacterial origin produced in situ in the gastrointestinal tract by specific selected bacterial strains, in association with vegetable gums and/or animal and/or vegetable gelatines, for use as a medication for the prevention and treatment of all pathologies connected to a deficiency in the barrier effect in the gastrointestinal area due to a low production of mucus, preferably in the case of intestinal permeability and bacterial translocation, as claimed in the appended claims.
For the sake of brevity, in the context of the present invention a composition or a medical device (composition for a medical device) will be referred to in general, in the remainder of the description, as "the compositions of the present invention".
The compositions of the present invention comprise or, alternatively, consist of at least one probiotic bacterial strain which is a producer of exopolysaccharides (abbreviated EPS) in association with a vegetable gum and/or an animal and/or vegetable gelatine.
Said at least one strain of EPS-producing strains is selected from the group comprising the bacterial strains belonging to the genera Streptococcus, Lactobacillus and Bifidobacteria. Said at least one bacterial strain is selected preferably from the group comprising or, alternatively, consisting of probiotic bacterial strains belonging to the species Streptococcus thermophilus, Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus pentosus, Lactobacillus acidophilus, Lactobacillus brevis, Lactobacillus reuteri, Bifidobacterium breve, Bifidobacterium bifidum, Bidifobacterium lactis, Lactobacillus fermentum and Lactobacillus delbrueeckii.
Said at least one bacterial strain is selected from the group comprising or, alternatively, consisting of probiotic bacterial strains belonging to the species Streptococcus thermophilus, Lactobacillus plantarum or Lactobacillus rhamnosus. Said probiotic bacterial strains must be EPS producers in situ in the gastrointestinal tract.
Advantageously, said EPS-producing bacterial strains belong to the species Streptococcus thermophilus.
The compositions of the present invention comprise or, alternatively, consist of one or two or three or four EPS- producing probiotic bacterial strains, selected from among the ones described, in association with a vegetable gum and/or an animal and/or vegetable gelatine.
The compositions of the present invention comprise or, alternatively, consist of one or two or three or four EPS- producing probiotic bacterial strains, selected from the group comprising or, alternatively, consisting of probiotic bacterial strains belonging to the species Streptococcus thermophilus, Lactobacillus plantarum or Lactobacillus rhamnosus in association with a vegetable gum and/or an animal and/or vegetable gelatine.
Advantageously, said one or two or three or four EPS-producing bacterial strains belong to the species Streptococcus thermophilus. Embodiments comprising mixtures of two or three or four bacterial strains selected from among probiotic bacterial strains belonging to the species Streptococcus thermophilus and/or Lactobacillus plantarum and/or Lactobacillus rhamnosus in association with a vegetable gum and/or an animal and/or vegetable gelatine are also part of the present invention.
A gum is a dehydrated or lyophilized or dried material in the form of a powder or flakes which on coming into contact with water produces a gum gel in water (aqueous gel) or a gum gelatine. Alternatively, an already prepared gel or gelatine can be validly used.
The gums used are all gums for oral use which are allowed and used in food supplements and medical devices. In one embodiment, the vegetable gum and/or the animal and/or vegetable gelatine is selected from the group comprising or, alternatively, consisting of Aloe, Aloe vera (Aloe vera -Aloe barbadensis Miller, is a plant of the Aloaceae family), Aloe arborescens, alginates, xyloglucans (or xylogels), tannates, gelatine tannate, carrageenans, pectins, agar-agar and tara gum.
Advantageously, the vegetable gum and/or the animal and/or vegetable gelatine is selected from the group comprising or, alternatively, consisting of Aloe arborescens, gelatine tannate and tara gum.
In one embodiment, use is made of gelatine tannate (a complex of gelatine and tannic acid), which acts by mechanical means to protect inflamed intestinal mucosae. Gelatine tannate forms a mucoadhesive protective film of protein origin which protects the intestinal mucosa. However, from the time it is ingested to the time it arrives at its destination in the intestine, a vegetable gum and/or an animal or vegetable gelatine undergoes a slow but inexorable degradation as it passes from the stomach to the intestine. The gum degrades and loses its effectiveness in restoring the physiological functions of the intestinal walls.
This degradation is due to multiple factors, such as, for example pH, enzymes, attacks from endogenous bacterial flora, the effect of the gastroduodenal barrier and a dilution effect. Practically speaking, there is a loss of effectiveness that occurs progressively as the gelatine tannate passes through the gastrointestinal tract, also as the result of an attack by acid, bile salts, pancreatic juices and enzymes. When the gelatine tannate arrives in the colon it is in part degraded and thus less effective in protecting the walls of the intestine against pathogenic bacteria, which are able to penetrate it by means of their flagella.
The Applicant has found that gum of bacterial origin, produced in situ by the strains of the present invention selected from the group comprising or, alternatively, consisting of probiotic bacterial strains belonging to the species Streptococcus thermophilus, Lactobacillus plantarum or Lactobacillus rhamnosus, on the one hand, and a vegetable gum and/or an animal and/or vegetable gelatine, on the other hand, each have an effect of their own and they are complementary to each other.
The first effect is a gelling effect exerted by the vegetable gum and/or the animal and/or vegetable gelatine, and which is maximum in the stomach (maximum protection) and minimum in the colon due to the degradation and consequent loss of effectiveness in protecting inflamed intestinal mucosae.
The second effect is a protective effect exerted by the gum of bacterial origin, in particular by exopolysaccharides (EPS) produced in situ by the strains of the present invention selected from the group comprising or, alternatively, consisting of probiotic bacterial strains belonging to the species Streptococcus ihermophilus, Lactobacillus plantarum or Lactobacillus rhamnosus. This second effect is minimum in the stomach and maximum in the colon, where the bacteria of the present invention, having arrived alive and vital and at a high concentration, produce EPS in situ.
Added together, these two mutually complementary effects ensure total coverage against bacterial infections in the stomach (due to the vegetable gum and/or the animal and/or vegetable gelatine) and in the gastrointestinal tract (due to the gum of bacterial origin).
The subject matter of the present invention relates to a composition or a medical device (composition for a medical device) for use as a medication for the prevention and the treatment of all pathologies connected to a deficiency in the barrier effect in the gastrointestinal area due to a low production of mucus.
The compositions of the present invention are capable of restoring the barrier effect that was lost because of insufficient protection of the mucosa in the gastrointestinal tract.
The compositions of the present invention are capable of preventing and treating infections, inflammations and disorders of the gastrointestinal tract, pathogenic bacteria, candidiasis and intestinal permeability.
The composition of the present invention is capable of forming a specific mucoadherent gelling complex, composed of EPS, exopolysaccharides of bacterial origin (produced by selected strains as specified below, belonging in particular to the species Streptococcus thermophilus, e.g. Streptococcus ihermophilus ST10 -DSM 25246, Streptococcus thermophilus (Y04) DSM 16592 or mixtures thereof in a ratio by weight comprised from 1 :2 to 2:1 , preferably 1 :1 , and tara gum, a polysaccharide of vegetable origin. Said gelling complex is capable of establishing a barrier effect of a mechanical type extending throughout the whole gastrointestinal tract.
Thanks to the presence of the gellant tara gum, the composition of the present invention is capable of forming a hydrogel within few minutes after ingestion, by virtue of its thixotropic characteristics, and of thereby creating, in the first part of the gastrointestinal tract, a barrier effect of a mechanical type against pathogenic bacteria and metabolites with pro-inflammatory action. This barrier effect is completed and extended for the entire length of the gastrointestinal tract by the presence of exopolysaccharides (EPS), produced in situ by probiotic bacterial strains belonging to the species Streptococcus thermophilus, as specified below, e.g. Sfrepfococcus thermophilus ST10, Streptococcus thermophilus YO04 or mixtures thereof, which serve to increase the viscosity of the surrounding environment through an exclusively mechanical, self-regulated mechanism. The intake of the aforesaid bacteria conveys into the human intestine a source of molecules with a gelling activity, thus exerting an action which is totally complementary to that of tara gum. The above-mentioned mucoadherent gelling complex has an innovative property to be taken into consideration: during its intestinal transit, tara gum (like all gums of vegetable origin) is progressively degraded by the resident microbiota, so that its mechanically opposing gelling power is progressively reduced. The gradual decrease in the action of the vegetable gum is effectively compensated for by the gradual increase in the release, in the intestinal lumen, of exopolysaccharides (EPS), for example by the bacterial strain ST10 and/or YO04, which manifests its particular characteristics above all in the ileum and in the colon. As a result, the synergetic combination of tara gum and exopoiysaccharides (EPS) ensures the presence of gelling molecules for the entire length of the gastrointestinal tract, thus maximizing and optimizing the mechanical barrier action of the product. The presence, production and retention of the hydrophilic gel in the lumen of the organ can therefore for the first time be considered really complete, with a first area in which the action of the vegetable gum is maximum and a second area in which the action of the exopoiysaccharides (EPS) is maximum.

Experimental part
1. The viscosity of samples of serum fermented with probiotic bacterial strains belonging to the exopolysaccharide (EPS) producing species S. thermophilus was evaluated. The viscosity was measured by means of a viscometer which measures the rotation of a suitably sized disk within the sample to be tested: the more friction the disk encounters the slower its rotation, the set speed being equal. The result is expressed in centipoises (CPs), in association with a percentage SP, which is an expression of the goodness of the data (the method requires it to be greater than or equal to 15%). The culture medium is 10% reconstituted serum pasteurized at 80 °C for 20 minutes, into which the strains specified below were inoculated at a concentration of 3%: Streptococcus thermophilus DSM 16590 (Y02), Streptococcus thermophilus DSM 16592 (Y04), Streptococcus thermophilus DSM 17843 (Y08), Streptococcus thermophilus DSM 25246 (ST10), Streptococcus thermophilus DSM 25247 (ST11) and Streptococcus thermophilus DSM 25282 (ST12).

2. Shown below are the analytic data found for a finished product in tablet form (tablets 1 to 8), based on identical mixtures which differed only in the gum used. Tara gum was used for tablets 1 , 3, 5 and 7, whereas guar gum was used for tablets 2, 4, 6 and 8, the other ingredients and concentrations being equal.
The above-mentioned tablets were prepared in an identical manner, using the same ingredients and the bacterial strains specified below.
Tablet 1 : strain ST10 -DSM 25246, excipients and tara gum.
Tablet 2: strain ST10 -DSM 25246, excipients and guar gum.
Tablet 3: strain ST10 -DSM 25246 and strain Y04 -DSM 16592, excipients and tara gum.
Tablet 4: strain ST10 -DSM 25246 and strain Y04 -DSM 16592, excipients and guar gum.
Tablet 5: strain ST10 -DSM 25246 and strain Y02 -DSM 16590, excipients and tara gum.
Tablet 6: strain ST10 -DSM 25246 and strain Y02 -DSM 16590, excipients and guar gum.
Tablet 7: strain ST10 -DSM 25246 and strain Y08 -DSM 17843, excipients and tara gum.
Tablet 8: strain ST10 -DSM 25246 and strain Y08 -DSM 17843, excipients and guar gum.
Compression tests were performed on the mixtures and the bacterial count was subsequently determined to evaluate the stress and mortality caused when forming the tablets.
