- EP-A-0.328.421 relates to a method for fixing known antibacterials using a polymer resin matrix, previously dissolved in an organic solvent. It is this resin which will then be fixed on the polymer. This method of attachment is indirect.
- Document EP-A-0.207.624 relates to the methods for the preparation of an anti-infective polymer directly, comprising different stages. First, immersion of the polymer in a solution of antimicrobial agents dissolved in an organic solvent, then immersion of the polymer in an organic solvent which may contain metal salts, finally immersion of the polymer in an organic solvent containing antimicrobials. It is dried after each immersion.
- Document EP-A-0.379.269 relates to the incorporation of chlorhexidine into a polymer during its manufacture. This technique involves heating as well as a quaternary ammonium of the tridodecyl methyl ammonium chloride (TDMAC) type, in order to allow subsequent fixing of the antibiotic. It is therefore an indirect use. On the other hand, the doctor who Wants to use this type of technique must immerse the polymer in the antimicrobial just before using it because there is no possibility of keeping the polymer treated with the antibiotic.
- Document EP-A-0.141.628 relates to the use of chlorhexidine and therefore of its cationic functions to fix it directly on latex. In this document, there is absolutely no question of fixing an antimicrobial or antibacterial afterwards.
- GB-A-2.093.348 uses plaster of Paris to fix the antimicrobial or the antibacterial.
- document O-A-8,904,674 relates to the fixing of an antimicrobial on a biodegradable polymer.
- Infections caused by implantation of prostheses can in particular be the cause of endocarditis and require difficult, if not impossible, treatments.
- the failure of these treatments most often leads to the ablation of the material; he there follows a significant social cost and a non-negligible risk for the patient.
- the present invention overcomes the problems of fixation and toxicity of the antibacterial substance, and thereby leads to improved efficiency.
- R x represents an alkyl, aminoalkyl or phenyl radical optionally substituted (by a halogen atom or a hydroxy, alkyl, alkyloxy or carboxy radical), naphthyl or cyano
- R 2 represents a hydrogen atom or an alkyl radical and n represents an integer ranging from 1 to 6, it being understood that the portions and alkyl radicals mentioned above are straight or branched and contain 1 to 4 carbon atoms, then
- Suitable antibacterial agents are chosen from the class of quinolones, ⁇ -lactams, fusidic acid, fosfomycin, teicoplanin, aztreoname or imipenem.
- the method according to the invention not only protects against bacterial proliferation, but in addition, by using biguanide as an adhesion agent, makes it possible to solve the double problem of poor adhesion of quinolones and other antibiotics to prostheses. , implants and catheters and the toxicity of biguanides when they themselves serve as an antibacterial substance.
- the cationic functions carried by the hydrogenated amino functions of biguanide and the anionic functions carried by antibiotics are used; said cationic and anionic functions form an ionic bond allowing the fixation of biguanide antibiotics.
- This method has the advantage of being able to be applied to any kind of prosthesis usable in medicine and of ensuring diffusion of the antibiotic directly from the implanted material.
- the catheters, implants and prostheses can be chosen from urinary catheters, probes, vascular and intra-arterial catheters, cardiac valve prostheses, arterial prostheses, pacemakers, orthopedic prostheses, implants ocular or dental, bypass shunts between two segments of the circulatory system, as well as sutures.
- the method according to the invention applies to various materials of constitution such as plastics, metals or sutures.
- the biguanide solutions used are advantageously chosen from aqueous or organic solutions in solvents such as alcohols (for example ethanol, methanol), propylene glycol, polyethylene glycols or glycerol.
- solvents such as alcohols (for example ethanol, methanol), propylene glycol, polyethylene glycols or glycerol.
- the preferred biguanides are chlorhexidine: hexamethylene bis [(p-chlorophenyl) -5 biguanide] - 1, l ', alexidine: hexamethylene bis [(2-ethyl hexyl) -5 biguanide] -! 'or 1' hexamethylene bis [aminohexylbiguanide] -1, l '. Solutions containing the antibiotic will be adapted to the nature and class of the antibiotic chosen.

- the effectiveness of the fixing of the antibiotic is achieved by assessing the antibiotic and antiadherential properties of the antibiotic fixed on the cups with respect to sensitive and / or resistant germs.
- the method used for the study of the adhesion properties is that described by CHRISTENSEN GD et al., J. Clin. Microb ol. , 22, 996-1006 (1985).
- a bacterial suspension inoculum of 10 6 CFU / ml obtained by diluting an overnight culture) is distributed in the wells of the microplate to be tested.
- results of the wells which have fixed the antibiotic are expressed as a percentage of adhesion with respect to the control (blank wells) and with respect to the chlorhexydine wells alone.
- Each experiment is carried out on the same plate in at least four wells and on three different plates.
- the methods of fixing the antibiotic are studied by varying: the concentrations of chlorhexidine and the concentrations of antibiotics.
- a study of the stability of the catheters as a function of time is carried out by measuring the antibiotic activity of the catheters stored for two months. Antibiotic activity is assessed in vitro by the KIRBY-BAUER method.
- the pieces of catheters are implanted vertically in an agar inoculated by flooding with a selected germ (Staphylococcus aureus, Escherichia coli, Micrococcus lutea, Enterobacter cloacae, Serratia marcescens ”). After incubation, one night at 37oC, the diameters of inhibition are measured, compared to those of uncoated catheters and chlorhexidine control catheters. It has thus been demonstrated by varying the concentrations of antibiotic (for example pefloxacin), that the fixation is dose-dependent.
- antibiotic for example pefloxacin
- a catheter impregnated with a solution containing 10% chlorhexidine and with a 2 g / 1 solution of pefloxacin is placed in 1 ml of buffer.
- the concentration of pefloxacin in the buffer is measured after 1 and 24 hours of incubation at 37oC: 2.4 and 2.6 mg / l respectively.
- the initial buffer is removed and then an assay is carried out after incubation at 37 ° C. overnight. The residual rate is then 0.3mg / l. This experiment shows that it is possible to release the antibiotic into the medium from the catheter. This release is effective from 1 to 24 hours.
- the protection method according to the invention is carried out by soaking the prosthesis, the implant or the catheter in a solution containing 20 to 100 g / l of biguanide, optionally washing, soaking in a solution containing 1 to 100g / l of antibiotic, then possibly washing, and drying.
- the duration of the soaking is not an essential factor for carrying out the invention. However, it is advantageous to soak for 1 to 24 hours in each of the solutions.
- the prostheses and / or catheters impregnated according to the method of the present invention are capable of gradually releasing the antibacterial substance into the implantation medium for at least 24 to 48 hours, and thus leading to the prevention of bacterial contamination of the materials. used.
- the present invention also relates to the device for protecting prostheses, implants and / or catheters obtained according to the method described above and capable of progressively releasing the antibacterial substance attached to the surface.
- the impregnation of prostheses, implants and / or catheters can be carried out indifferently beforehand, for example following the manufacture of the prosthesis or at the time of use.
- the present invention also relates to equipment making it possible to easily impregnate the catheter, implant or prosthesis.
- Such equipment consists of: a) a solution containing 20 to 100 g / l of the biguanide of general formula (I) for example called solution No 1 and intended for the first impregnation and b) a solution containing 1 to 100 g / 1 of the antimicrobial substance, for example called solution No 2 and intended for the second impregnation.
- such equipment may also include, instead of the bottle of ready-to-use solution, a bottle of solvent and the appropriate quantity of the substance which will be dissolved immediately by the user at the time of use.
- Impregnation with the biguanide solution can also be carried out as soon as the material to be implanted is manufactured, the second impregnation being able to be considered at the time of use, for example in the case of an unstable antibiotic.
