Full textThe occurrence of prosthetic joint infection (PJI) is the main complication of joint prosthetic surgery since its invention by Robert and Jean Judet in 1947. Since the number of articular prostheses placed each year increases significantly, these infections are more and more frequent and the optimization of their management is an important medical and economic stake.The animal models of PJI make it possible to understand the ethiopathogenic mechanisms and to test new therapeutics. A critical analysis of the literature was carried out by evaluating each model according to its type of inoculation which influences the rates and the severity of the experimental infection obtained.An experimental model of PJI in rabbits obtained by partial replacement of the knee and local inoculation was used to test the efficacy of new therapeutics during infections with two multi-resistant bacteria which pose problems in human therapeutics.In a first step we evaluated the efficacy of ceftaroline (CPT) cephalosporin bactericidal in vivo against methicillin-resistant Staphylococcus aureus (MRSA) by comparing it with vancomycin (VAN) in combination with or without rifampin (RIF). 5.107UFC MRSA (Minimum Inhibitory Concentration (MIC) of 0.38, 0.006, and 1 mg/l for CPT, RIF, and VAN, respectively) was injected into the knee. Infected animals were randomized to receive no treatment (control), CPT (60 mg/kg im), VAN (60 mg/kg im), CPT plus RIF (10 mg/kg im) or VAN plus RIF, 7 days after inoculation and for 7 days. The efficacy of treatments was evaluated on the amount of persistent bacteria in the bone (proximal tibia) after treatment. This work has shown that CPT and VAN were effective as monotherapy, but only the combination with RIF allowed the sterilization of almost all animals. CPT appears to be a potentially effective treatment in this infection.In a second step we studied the efficacy of colistin (COL) in cement, alone or in combination with intramuscular (im) injections of COL and/or meropenem (MRP) in carbapenem-resistant Klebsiella pneumoniae infections (KPC). A model close to that used for MRSA was used. The strain KPC99YC is a clinical strain, resistant to gentamicin (MIC 8mg/L) intermediate to imipenem (MIC 4mg/l), and sensitive to COL (MIC 0,25mg/l). The inoculum was 1,109UFC. Seven days after the infection, the prosthesis were replaced by antibiotic-free spacer (control), or by COL-impregnated spacer (3 MIU of COL/40g of cement), or by antibiotic-free spacer and COL injections (12 mg/kg im), or the combination of the two, or COL injections with COL-impregnated cement spacer associated or not with MRP injections (80 mg/kg im). The treatment lasted 7 days. All control rabbits were infected at D15, with median and interquartile range (IQR) bone bacterial count of 6.17 [5.69, 7.04] CFU/g of bones. In contrast to local COL, systemic COL alone or combined with MRP was more effective than control on bacterial counts in bone at the end of treatment. The combination of COL local + systemic was significantly more effective than control group on bacterial counts. Interestingly it was the only effective regimen on the number of rabbits with sterile bone and at the limit of significance vs systemic treatment alone. One COL-resistant strain was detected in the COL local treatment alone but not with the combination of local and systemic COL.Direct inoculation modes are most effective in reproducing an acute PJI. The experimental studies allow testing innovative treatments in particular for the infections with multi-resistant bacteria

Full textProthesis joint infection (PJI) remains a major problem including patient damage, long-term hospitalization, elevated cost, difficult diagnosis and treatment. The physiopathological elements associate the presence of foreign material, a pathogenic agent and an immune reaction and tissue. Microbiological characteristics such as bacterial virulence, of the mechanisms of protection (slime), regulation (biofilm) and metabolic adaptation (variant microcolonies) are added to this immunizing disturbance. The principal objective of this work was to better understand the physiopathological mechanisms of the PJI, in particular the role of the prosthetic wear (UHMWPE : Ultra Hight Molecular Weight Polyethylene) remains in the neutrophil bacterial activity. Our work shows that the UHMWPE cause a major bactericidal disturb of neutrophil. We also propose, in collaboration with the Biopuces department of the CEA, a innovating method to detect these UHMWPE particles

Full textOsteoarticular infections (OAI) often require a surgical procedure with prosthesis removal followed by long-term complex antibiotherapy. The ability of Staphylococcus aureus to adhere and produce biofilm on the surface of implanted material contributes to treatment failures and microbiological relapses. In addition, biofilm formation can be induced by some antibiotics at sub-minimal inhibitory concentrations (sub-MICs). The present study characterizes in vitro the effects of 12 antibiotics on biofilm formed by a strain of methicillin-susceptible Staphylococcus aureus isolated from an osteo-articular infection.The influence of these antibiotics was assessed on biofilm formation at concentrations including the breakpoints, by numbering viable cells in the biofilm biomass and in the suspensions (unattached cells) surrounding the biofilm. Biofilm formation was prevented in presence of ceftarolin, daptomycin, fosfomycin, gentamicin, ofloxacin, rifampicin and vancomycin at the highest concentrations tested. Only fosfomycin showed inhibition properties also at sub-MICs. Unattached and sessile viable bacteria were undetectable to daptomycin and gentamicin at the highest concentrations tested.Determination of the minimum biofilm eradication concentrations (MBECs) indicated that in vitro eradication of 24h-old biofilms required concentrations at least 800 times higher than the planktonic MIC, concentrations obviously not compatibles with classical therapeutic doses.In the second part of this work, we focused our study on the action of fosfomycin, because of its effect on biofilm formation and its therapeutic interest. A transcriptome analysis was performed with sessile cells from both biofilm formed in the presence of sub-MIC of fosfomycin and cells from pre-formed 24h-old biofilm treated by fosfomycin at sub-MBEC. Fosfomycin induced mostly down regulation of genes assigned to nucleotide, amino acid and carbohydrate transport and metabolism. Adhesins and capsular biosynthesis proteins (ScdA) encoding genes were also down regulated. To a lesser extent, peptidoglycan biosynthesis proteins (MGT and MurA) and autolysins encoding genes were found down regulated. Metabolic slowdown and cell membrane modifications induced by fosfomycin are likely to be responsible for the impairment of bacterial adhesion capacity.The action of fosfomycin at sub-MIC on unattached cells surrounding biofilm was also analyzed. Surprisingly, they displayed higher capacity to form new biofilm than their counterparts obtained without fosfomycin, probably associated with their large peptidoglycan layer.In conclusion, these data underline the relevance of the use of fosfomycine in preventing osteo-articular infections due to S. aureus and should be assessed in in vivo experiments. However, simultaneous eradication of unattached cells should also be considered due to the high capacities of these cells to disseminate and establish new biofilm, a real risk of treatment failure

Full textThe aim of this thesis was to contribute to the understanding of the physiopathology of C. acnes orthopedic-device related infections (ODRI). Firstly, we typed by MLST 108 C. acnes isolates responsible for 34 cases of monomicrobial ODRIs and correlated typing results with bio-clinical data. We have shown that C. acnes ODRIs correspond to two clinical entities: i) "homotypic" cases corresponding to true infections with a single pathogenic clone of C. acnes eliciting an inflammatory response ii) heterotypic cases corresponding to colonization or iterative contamination of the implant without systemic inflammatory response. These typing data highlighted the limitations of the current microbiological definition of ODRI when it comes to C. acnes and the need to incorporate a reliable molecular tool into the routine microbiological diagnosis of these infections. We therefore evaluated the SLST technique developed for a rapid and optimal typing of C. acnes. The discriminating power of this technique was insufficient suggesting that only the establishment of real-time NGS in microbiology laboratories could improve the microbiological diagnosis. Our typing results showed that the clonal status of the infection and not CC is the main determining factor in the physiopathological and inflammatory process of C. acnes ODRI. This conclusion is consistent with our results obtained on an in vitro model of a macrophage THP-1 infection. Using this model, we have shown that the in vitro inflammatory response of our isolates is strain- and non-CC-dependent. In addition, the in vitro and in vivo inflammatory responses were not correlated. This underscores the limitations of in vitro models in the study of C. acnes ODRIs in which the adaptation of the bacteria to the host is completely neglected during the study of the immune response. Finally, we confirmed the importance of the environment in the conditioning of the behavior of the bacterium. We conducted a comparative study of the ex vivo and ex vitro growth characteristics of our C.acnes isolates. We have shown the impact of CC and environmental conditions, by extension the pressure that can exert the host, on the cultural profile of C. acnes. In conclusion, our work shows that a multifactorial approach, integrating both genomics and host response, is needed to understand the physiopathology of C. acnes ODRI

Full textOne target of surgical site infections (SSI) surveillance is hip or knee arthroplasty infections (HKAI), however, HKAI incidence estimations are considered to be poorly effective, especially regarding data collection and patient follow-up. In France, each hospital discharge must be registered in the National Hospital Discharge Database (HDD), convenient and permanent medico-administrative database that can be mined for epidemiological studies and evaluation. This study aims to assess performance criteria of using the HDD as an additional tool to survey SSI occurring after HKA and to study its use in routine. A cohort study was conducted using retrospectively collected regional data from the French HDD. Surveillance of HKAI occurrence was performed based on various algorithms using the ICD-10, and the classification of procedures in a case-control study nested in the cohort. The HKAI case definition was validated by checking 1,000 medical charts as the gold standard, giving performance criteria as Se 97%, Spe 95%, PPV 87%, PNV 98%. The HKAI incidence density was 2.2/100 pers-year [CI95% 2.0- 2.6] and risk factors were male gender, undernutrition, obesity, chronic diseases. The median time for HKAI occurrence was 71 days (1-1,650 d), but 1/3 of HKAI occurred more than one year after arthroplasty. The HDD potential for routine SSI surveillance in low risk surgery was demonstrated, under conditions of having appropriate algorithm for selecting infections
