Definitions
- Composition comprising at least one probiotic bacterium and intended to be used for the treatment of oral mycosis
- the present invention relates to a composition
- a composition comprising at least one probiotic bacterium and intended to be used for the preventive and / or curative treatment of oral mycoses, in particular intended to be used for the preventive and / or curative treatment of oral candidiasis. , especially oral candidiasis caused by yeast Candida albicans.
- Oral mycosis is common and due to the excessive presence of yeasts or fungi in the mouth.
- Oral mycosis includes acute or chronic oral candidiasis and deep fungus infections of the oral cavity, such as cryptococcosis, mucormycosis, aspergillosis, histoplasmosis, paracoccidioidomycosis. or coccidioidomycosis.
- oral candidiasis is the most common, the latter being generally caused by Candida-type yeast (Candida tropicalis, Candida glabrata, Candida parapsilosis, Candida krusei, Candida stellatoidea, Candida pseudotropicalis, Candida famata, Candida rugosa, Candida geotrichium, Candida dubliniensis, Candida guilliermondii and Candida albicans).
- Candida-type yeast Candida-type yeast
- yeast Candida albicans The most common form of oral candidiasis is that caused more specifically by yeast Candida albicans. This yeast is naturally present in about 35 to 50% of individuals but can cause mycosis of the mucous membrane of the mouth when it proliferates excessively to the point of becoming pathogenic and attacking the host tissues. This is an opportunistic infection in the sense that it is due to germs usually not very aggressive but which are likely to cause serious complications under the influence of local or systemic factors affecting for example the immune system. When yeast Candida albicans gives rise to oral candidiasis, there is a common pattern of "lily of the valley" in the mouth, which is responsible for acidic, metallic, bitter or salty taste in the mouth, and more rarely burning sensation in the mouth.
- Candida-type yeasts that is the number of pathological cases caused by Candida-type yeasts, varies according to many factors but a high prevalence has been observed during the summer months in women and in hospitalized individuals.
- a high proliferation of this yeast has also been noted in individuals consuming a diet rich in sugars, in individuals wearing a dental prosthesis, in individuals suffering from xerostomia (dry mouth), in people consuming broad-spectrum antibiotics and / or or corticosteroids and / or neuroleptics, in smokers, in immunocompromised individuals (eg due to HIV, diabetes, Down syndrome or malnutrition) and in individuals with cancer (treatment cancer such as chemotherapy and radiotherapy being factors that promote the development of these yeasts).
- Age is also an important factor: a relatively low prevalence is observed in newborns and then increases drastically in children before decreasing in adulthood. It should be noted that neonates often suffer from oral mycosis and more particularly from oral candidiasis since their immune system is not yet able to fight against a proliferation of yeast of the Candida type, such as for example yeast. Candida albicans. Newborns (about 5% of them) acquire Candida-like yeasts when they are born by transmission from their mother's vaginal canal. The Elderly people are also at risk and often subject to oral mycosis and therefore to oral candidiasis since they frequently combine several contributing factors, such as dry mouth and medication.
- dental prostheses are a relatively acidic, moist and anaerobic (because the mucosa covered by the prosthesis is protected from oxygen and saliva), which is favorable to the development of Candida type yeasts.
- poorly fitting dental prostheses can damage the oral mucosa, which increases its permeability and facilitates tissue invasion by, for example, yeast Candida albicans. Damage to dental prostheses can also contribute to Candida-type yeast overgrowth as a result of the formation of skin folds in the corners of the mouth, forming intertriginous areas where another form of candidiasis, the perleche, can occur. develop.
- Candida species are able to adhere to the surface of dental prostheses, most of which are made from polymethacrylate in which micro-fissures and cracks favorable to retention of these yeasts can form. It is not uncommon for dental prostheses to be covered with a biofilm forming a real reservoir of infection that can infect the mucosa. For this reason, the disinfection of the prosthesis is an essential part of the treatment of oral candidiasis in people who wear dentures, just as a good fit of the prosthesis in the mouth.
- Candida-type yeasts grow and adhere (possibly biofilm-forming) more rapidly in the presence of carbohydrates such as glucose, galactose and sucrose.
- oral mycosis and more particularly oral candidiasis are mainly treated with local antifungals (such as nystatin, amphotericin B or miconazole) for a duration of treatment of at least 10 to 15 days for the forms. acute and at least 3 weeks for chronic forms.
- local antifungals such as nystatin, amphotericin B or miconazole
- probiotic bacteria that is, the use of bacteria that have a beneficial effect on health. It is known that several probiotic bacterial strains are capable of breaking the biofilm formed by yeasts or that these probiotic bacteria have the capacity to slow the growth of these yeasts, in particular by modifying the pH of the surrounding medium or by affecting other mechanisms related to the development of yeasts, including the development of Candida type yeasts.
- a publication discloses that probiotics of the Lactobacillus type, and more particularly the bacteria Lactobacillus rhamnosus GG (LGG), Lactobacillus casei Shirota, Lactobacillus reuteri SD21 2, Lactobacillus brevis CD2, Lactobacillus bulgaricus LB86 and Lactobacillus bulgaricus LB Lact act as that inhibitors of the growth of Candida type yeasts and that they therefore allow potentially to treat this pathogenic yeast when it proliferates abnormally, that is to say to treat oral candidiasis (Jiang et al., 2015. Benef Microbes, 6 (3): 361-368).
- Another document indicates the inhibitory effect of a combination of probiotics Lactobacillus casei and Bifidobacterium brief on the development of Candida-type yeasts, this mixture of probiotics being administered in the form of a drink (yogurt) to elderly patients suffering from oral candidiasis. According to the results of this study, approximately 57% of treated patients were able to see Candida populations significantly reduced while a total elimination of this yeast was observed in only about 2% of patients (Mendonça et al., 2012 J. Dent, Braz., 23 (5): 534-538).
- WO99 / 17788 discloses a method for treating infections caused by Candida including in the mouth. More particularly, this document describes tests carried out on mice to which various probiotics have been administered enterally in the form of a freeze-dried powder.
- the probiotics tested are L. reuteri, B. infantis, B. lactis, L. acidophilus and L. casei and this document contemplates that these may be associated with one or more other probiotics including L. casei rhamnosus and L. rhamnosus.
- LGG L. casei GG strain
- EP2455095 relates to a therapeutic use of a L. rhamnosus type probiotic for treating dental oral infections.
- the tests carried out in this prior document by oral administration of L. rhamnosus strain K03 as probiotic show that the latter does not make it possible to ensure complete elimination of Candida.
- Hassloff et al. (BMC Oral Health, 10 (18), 2010) is an in vitro study testing the efficacy of various probiotics including L. rhamnosus LB21 and L. rhamnosus LGG to treat / inhibit the growth of Candida albicans.
- these probiotics are administered in vivo by being formulated in yogurt but that such a formulation is certainly not adequate since the document by Mendonça et al. shows that a formulation of Lactobacillus in a yogurt is far from effective.
- the object of the invention is to overcome the disadvantages of the state of the art by providing a composition as indicated at the beginning, characterized in that the said at least one probiotic bacterium is the probiotic bacterium Lactobacillus rhamnosus No. LMG S-28148 .
- oral candidiasis algae is meant that this most common form of candidiasis is due to local factors.
- chronic oral candidiasis is meant that this form of candidiasis, more rare, is mainly but not exclusively due to a deficiency of the immune system.
- a composition comprising the probiotic Lactobacillus rhamnosus No. LMG S-28148 makes it possible to treat acute or chronic oral mycosis, in particular acute oral candidiasis, in just a few minutes. days.
- a composition according to the invention is effective and provides treatment and elimination of oral mycosis, including treatment and elimination of acute oral candidiasis, in an average duration of only 3 to 5 days or even 7 days whereas current treatments based on formulations including probiotics require a treatment duration of at least 15 days or even several weeks without guaranteeing an effective treatment.
- composition according to the invention allows rapidly, that is to say in 2 or 3 days or even 5 days and maximum in one week, to stop any proliferation of Candida-type yeasts, in particular any proliferation of yeast Candida albicans, and to completely treat oral mycosis such as acute oral candidiasis.
- composition according to the invention also comprises at least one additional probiotic chosen from the group consisting of the following probiotics: Archaea, Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria, Verrucomicrobia, Fusobacteria, andanobacteria, Spirochaetes, Fibrobacter, Deferribacteria, Deinococcus, Therrnus, Lactobacillus, Cyanobacteria, Methanobrevibacterium, Peptostreptococcus, Ruminococcus, Coprococcus, Subdolingranulum, Dorea, Buileidia, Anaerofustis, Gemellose, Osteopathia, Catenibacterium, Dialister, Anaerotruncus, Staphylococcus, Micrococcus, Propionibacterium, Enterobacteriaceae, Faecalibacterium, Bacteroides, Parabacteroides, Prevotella, Eubacterium, Akker
- the composition according to the invention is in an orosoluble or orodispersible form.
- the composition according to the invention may be in the form of a dry orosoluble powder that will mix with saliva and thus disperse quickly and homogeneously in the mouth.
- said orosoluble or orodispersible form of a composition according to the invention solubilizes or disperses in a few seconds, for example in 15 seconds, preferably in 10 seconds, preferably in 5 seconds, preferably in 2 to 3 seconds. These times were determined to be adequate so that the probiotic bacterium Lactobacillus rhamnosus No. LG S-28148 and possibly one or more additional probiotic bacteria of the composition according to the invention can provide optimal treatment of oral mycosis, for example the candida then acting on yeast Candida albicans whose proliferation is blocked and treatment (elimination) ensured.
- said orosoluble or orodispersible form of a composition according to the invention is a powder in sachet or not, a seal or a tablet. Any other suitable orosoluble or orodispersible form is also within the scope of the present invention.
- the composition according to the invention is in the form of a dry syrup.
- dry syrup denotes a form of the composition according to the invention which, once dissolved in a liquid or semi-liquid vehicle, makes it possible to constitute a liquid dosage for oral administration.
- the composition according to the invention is in a liquid or semi-liquid form.
- said liquid or semi-liquid form of a composition according to the invention is a suspension, a dispersion, a gel, a paste, a syrup, a toothpaste, a chewing gum, an oral liquid, a mouthwash, an emulsion or a microemulsion.
- said liquid or semi-liquid form of a composition according to the invention is an aqueous or oily form.
- composition according to the invention further comprises additional excipients chosen from the group consisting of gums, cellulose, acrylic derivatives, thixotropic agents, stabilizing agents, preserving agents, and mixtures thereof.
- composition according to the invention further comprises one or more polymers and / or one or more compounds for conferring viscoelastic properties.
- Such additional excipients and such polymers or compounds for imparting viscoelastic properties may make it possible to impart suitable properties to the following composition the invention, for example an adequate viscosity allowing the composition to be distributed throughout the mouth, that is to say to come into contact with all the tissues of the mouth, so that the bacterium probiotic Lactobacillus rhamnosus No. LMG S-28148 and optionally one or more additional probiotic bacteria of the composition according to the invention can provide optimal treatment of oral mycosis, for example oral candidiasis by acting then on yeast Candida albicans whose proliferation is blocked and treatment (elimination) ensured.
