Definitions

  • the invention relates to a preparation for the therapy and in particular prophylaxis of diseases of the digestive tract which occur in the presence of pathogenic and / or facultative-pathogenic bacteria.
  • Replacement blaff can trigger pylori.
  • Proteus vulgaris should also be mentioned, which, like Helicobacter pylori, is urease-positive. Mixed infections are very common.
  • Helicobacter pylori and gastric carcinoma A reference to a connection between Helicobacter pylori and gastric carcinoma can be found in the article "Helicobacter pylori and gastric carcinoma", R.J.L.F. Loffeld, I. Willems, J.A. Flendrig & Arends, J.W. Histopathology 1990, 17, pages 537-541.
  • REPLACEMENT LEAF essential for the repression of pathogenic germs.
  • acid suppression favors certain aetiopathogenetic factors for various gastrointestinal lesions (eg gastric carcinoma and carcinoids).
  • acid suppression is obsolete and should be replaced by lantibiotic prophylaxis and therapy for ethical and economic reasons.
  • the object of the present invention is therefore to provide a preparation of the type mentioned in the introduction in such a way that it ensures high effectiveness without side effects.
  • a defined dose of a polypeptide antibiotic is contained as the active substance, the application of which achieves an active substance concentration of at least 5 ⁇ g / ml at the site of action.
  • nisin The antibacterial activity of lantibiotics, in particular nisin, is already known.
  • a use as a food additive is described for example in EP-A-0 453 972.
  • the antibacterial activity of nisin is also specified in US Pat. No. 5,043,176.
  • the use of nisin in the cosmetic field is described in DE-OS 39 38 140.
  • the bacteria mentioned at the beginning are the etiopathogenetic factor for chronic gastritis. This leads to mucosal atrophy and intestinal metaplasia over time. The end stage of these processes is usually a stomach tumor.
  • REPLACEMENT LEAF reduce. Colonization of the stomach with pathogenic bacteria (e.g. Gastrospirillum hominis or Helicobacter pylori) can lead to a weakening of the mucous membrane resistance, so that patients who regularly take corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDS) are dependent to develop peptic ulcers.
  • pathogenic bacteria e.g. Gastrospirillum hominis or Helicobacter pylori
  • NSAIDS non-steroidal anti-inflammatory drugs
  • nisin is medically harmless since it is not absorbed and is inactivated by pancreatic enzymes, in particular alpha-chymotrypsin.
  • the medication is applied until the aim of the treatment, namely germination, has been achieved. Since many of the bacteria discussed occur ubiquitously, reinfection cannot be ruled out.
  • Erosions chronically active gastritis chronically inactive gastritis chronically inactive gastritis (e.g. atrophic) chronically inactive gastritis with metaplasia and / or dyplasia other gastritis acute gastritis
  • Bacteria e.g. Brunner's glands
  • endocrine disorders such as hypergastrinemia
  • Hyperpepsinogenemia mental disorders e.g. depression
  • Gastropathies e.g. protein-losing hypertrophic gastropathy or gastric lymphoma
  • Nisinoid substances are resistant to gastric juice because they contain lanthionine and / or methyllathionine and can even exert their optimal effect at a pH of 1-2, which is typically present in the stomach.
  • nisinoid substances are also indicated in domestic and farm animals as well as laboratory and zoo animals. Bacteria were found in these animals that occur in the same ecological niche as Helicobacter pylori in humans. Helicobacter pylori is human-specific under normal conditions and, with the exception of the monkey, does not occur in the animals mentioned above.
  • the bacteria of the Campylobacter-Helicobacter complex isolated from animals induce gastrointestinal lesions which are comparable to humans, so that the use of nisine also appears to be economically sensible here. In addition, they are often transferred to humans and then generate the image known from Helicobacter pylori. This spectrum of germs should also be tackled with nisinoid substances.
  • the water solubility of nisin can be used in the manufacture and use of the preparation.
  • the water solubility is dependent on the respective pH value and is 12 grams for a quantity of water of 100 milliliters at a pH of 2.4, 1 gram at a pH of 5.6 and 0.075 grams at a pH of Value of 7.0. This means that water solubility is particularly high at low pH values.
  • non-polar water 100 milliliters at a pH of 2.4, 1 gram at a pH of 5.6 and 0.075 grams at a pH of Value of 7.0.
  • REPLACEMENT LEAF Solvents have a comparatively pronounced insolubility.
  • Nisin belongs to the group of polypeptide antibiotics, subgroup Lantibiotica, and consists of 34 amino acids. This polypeptide is used by certain strains of Lactococcus lactis ssp. produced.
  • Lantibiotics the preferred formation of which can be seen in subtilin, nisin and nisinoid substances, are also understood to mean, inter alia, bacteriocins which contain lanthionine and / or methyl lanthionine.
  • nisinoid substance is formed as nisin.
  • Nitinoid substances can be produced biotechnologically or generated synthetically.
  • mutants superior to the natural substance can be produced.
  • this makes it possible to change the chemical configuration, for example by introducing new amino acids or replacing or deleting amino acids or certain chemical groups.
  • a combination of the nisinoid substance with preparations that lead to a reduction of the mucosal barrier potentiates the effectiveness (e.g. lysozyme, cyclooxygenase inhibitor, cationic detergents, chelators, etc.).
  • the lysozyme acts e.g. not only synergistic, it also delays the development of resistance and, like nisin, is enteric-resistant.
  • a combination with permeabilizers is intended.
  • gastrointestinal diseases can be attributed to the fact that, for example, Helicobacter pylori persists intracellularly in gastric epithelial cells. These intracellular germs could not be reached with previous therapy methods. With the help of liposomes or proteoliposomes, nisin can be easily infiltrated into the infected cells and thus kills the bacteria. This eliminates the risk of recurrence.
  • the dose to be administered be designed as a capsule filling.
  • the dosing amount can be realized in an arrangement within a capsule, for example, such that the filling is in the form of a powdery substance
  • ER SA TZBLATT is. But it is also possible that the filling is designed as a solution of the substances or that a dispersion (suspension or emulsion) is present.
  • the metered amount it is possible for the metered amount to be arranged in the area of a tablet.
  • a delayed release of the preparation from a special galenical formulation is conceivable.
  • liposomes or hydrogels can be used in accordance with the publication "Hydrogels: Swelling, Drug Loading, and Release", SW Kim et al. , Pharmaceutical Research, 9, 1992, pages 283-290, bioadhesive materials of natural and synthetic origin are also used. Further galenical formulations in this regard can be found in 1 of the publication "Formulations releasing the drug proximal to the pylorus in the dog", J. Heinämäki et al. , International Journal of Pharmaceuticals, 48 (1988), pages 51-61.
  • the metered amount is contained in a meterable liquid and is administered orally.
  • a meterable liquid for example, there may be a solution or dispersion.
  • Oral administration is generally expedient in gastric and small intestine applications.
  • the application should be rectal.
  • composition of the preparation can be supplemented by the following auxiliaries, e.g. Preservatives, buffer substances, carriers, flavoring agents, colorants, binders, adhesives, lubricants, adsorbents, thickeners and thinners. Due to the decades-long, safe use in food preservation, it seems appropriate to include the active ingredient composition
  • acidic beverages e.g. fruit juices, cola drinks
  • Other foods with broad acceptance among the population are also conceivable as carriers of the preparation (eg milk).
  • Diseases of the digestive tract are understood to mean diseases of the intestine, stomach and esophagus.

  • the strains were stored as frozen foods (10% glycerine additive) or on transport medium carriers (Transwab) at -172 ° C.
  • the concentrations to be tested were added to the still liquid culture medium as a 10-fold concentrated solution and mixed thoroughly with the culture medium in a ratio of 1:10. After the agar had solidified, the test strains were inoculated onto the agar plates of different nisin concentration as a solid inoculum and, as required in the DIN, as a germ suspension.
