Alegrete N, Sousa SR, Peleteiro B, Monteiro FJ, Gutierres M. Local Antibiotic Delivery Ceramic Bone Substitutes for the Treatment of Infected Bone Cavities and Bone Regeneration: A Systematic Review on What We Have Learned from Animal Models. MATERIALS (BASEL, SWITZERLAND) 2023; 16:2387. [PMID: 36984267 PMCID: PMC10056339 DOI: 10.3390/ma16062387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 03/10/2023] [Accepted: 03/14/2023] [Indexed: 06/18/2023]
Abstract
AIMS the focus of this study is to evaluate if the combination of an antibiotic with a ceramic biomaterial is effective in treating osteomyelitis in an infected animal model and to define which model and protocol are best suited for in vivo experiments of local bone infection treatment. METHODS a systematic review was carried out based on PRISMA statement guidelines. A PubMed search was conducted to find original papers on animal models of bone infections using local antibiotic delivery systems with the characteristics of bone substitutes. Articles without a control group, differing from the experimental group only by the addition of antibiotics to the bone substitute, were excluded. RESULTS a total of 1185 records were retrieved, and after a three-step selection, 34 papers were included. Six manuscripts studied the effect of antibiotic-loaded biomaterials on bone infection prevention. Five articles studied infection in the presence of foreign bodies. In all but one, the combination of an antibiotic with bioceramic bone substitutes tended to prevent or cure bone infection while promoting biomaterial osteointegration. CONCLUSIONS this systematic review shows that the combination of antibiotics with bioceramic bone substitutes may be appropriate to treat bone infection when applied locally. The variability of the animal models, time to develop an infection, antibiotic used, way of carrying and releasing antibiotics, type of ceramic material, and endpoints limits the conclusions on the ideal therapy, enhancing the need for consistent models and guidelines to develop an adequate combination of material and antimicrobial agent leading to an effective human application.

Abstract
Surgical site infections (SSIs) are a persistent clinical challenge. Local antimicrobial delivery may reduce the risk of SSI by increasing drug concentrations and distribution in vulnerable surgical sites compared to what is achieved using systemic antimicrobial prophylaxis alone. In this work, we describe a comprehensive in vivo evaluation of the safety and efficacy of poly(N-isopropylacrylamide-co-dimethylbutyrolactone acrylamide-co-Jeffamine M-1000 acrylamide) [PNDJ], an injectable temperature-responsive hydrogel carrier for antimicrobial delivery in surgical sites. Biodistribution data indicate that PNDJ is primarily cleared via the liver and kidneys following drug delivery. Antimicrobial-loaded PNDJ was generally well-tolerated locally and systemically when applied in bone, muscle, articulating joints, and intraperitoneal space, although mild renal toxicity consistent with the released antimicrobials was identified at high doses in rats. Dosing of PNDJ at bone-implant interfaces did not affect normal tissue healing and function of orthopedic implants in a transcortical plug model in rabbits and in canine total hip arthroplasty. Finally, PNDJ was effective at preventing recurrence of implant-associated MSSA and MRSA osteomyelitis in rabbits, showing a trend toward outperforming commercially available antimicrobial-loaded bone cement and systemic antimicrobial administration. These studies indicate that antimicrobial-loaded PNDJ hydrogels are well-tolerated and could reduce incidence of SSI in a variety of surgical procedures.

Abstract
The development of infections is one of the main complications in orthopaedics, especially in the presence of implants for the osteosynthesis of compound fractures and joint prosthesis. Indeed, foreign materials and implants act as substrates for the adhesion and proliferation of bacterial strains able to produce biofilm, causing peri-implant osteomyelitis. The eradication of biofilm remains a great challenge for the host immune system, as well as for medical and surgical approaches, thus imposing the need for new prophylactic and/or therapeutic strategies in which animal models have an essential role. In vivo orthopaedic models have mainly been used to study the pathogenesis of infections, biofilm behaviour and the efficacy of antimicrobial strategies, to select diagnostic techniques and test the efficacy of novel materials or surface modifications to impede both the establishment of bone infections and the associated septic loosening of implants. Among several models of osteomyelitis and implant-related infections described in small rodents and large animals, the rabbit has been widely used as a reliable and reproducible model of orthopaedic infections. This review examines the relevance of rabbits for the development of clinically representative models by analysing the pros and cons of the different approaches published in the literature. This analysis will aid in increasing our knowledge concerning orthopaedic infections by using this species. This review will be a tool for researchers who need to approach pre-clinical studies in the field of bone infection and have to identify the most appropriate animal model to verify their scientific hypothesis.

Abstract
In spite of the vast research on developing a highly elastic polymer for tissue regeneration, using a renewable resource and a simple, environment-friendly synthesis route to synthesize an elastic polymer has not been successfully achieved yet. The objective of this study was to use a simple melt condensation polymerization method to develop an elastic polymer for tissue regeneration applications. A nature-derived renewable, nontoxic, and inexpensive monomer, xylitol, and a cross-linking agent, dodecanedioic acid, were used to synthesize the new polymer named poly(xylitol-dodecanedioic acid) (PXDDA). Its physicochemical and biological properties were fully characterized. Fourier transform infrared (FTIR) results confirmed the formation of ester bonding in the polymer structure, and thermal analysis results demonstrated that the polymer was completely amorphous. The polymer is highly elastic. Increasing the molar ratio of dodecanedioic acid resulted in lower elasticity, higher hydrophobicity, and lower glass transition temperature. Further, the polymer degradation rate and in vitro dye release from the polymer also became slower when the amount of dodecanedioic acid in the composite increased. Biocompatibility studies showed that both the polymeric materials and the degraded products of the polymer did not show any toxicity. Instead, this new polymer significantly promoted cell adhesion and proliferation, compared to a widely used polymer, poly(lactic acid), and tissue culture plates. Interestingly, the PXDDA polymer demonstrated autofluorescent properties. Overall, these results suggest that a new, elastic, biodegradable polymer has been successfully synthesized, and it holds great promise for biomedical applications in drug delivery and tissue engineering.

Abstract
Joint prostheses are an essential element to improve quality of life. However, prostheses may fail due to several factors, including the most frequent cause, Staphylococcus aureus infection. The identification of new fixing bone cements with less reactivity on bone tissue and an adequate response to infection remains a primary challenge. The aim of this study is to evaluate the response of bone tissue in rabbits after introduction of a hydroxyapatite‐coated titanium rod with a commercial fixative cement (Palacos®) compared to a modified experimental cement (EC) containing polylactic‐co‐glycolic acid (PLGA) microspheres in the presence or absence of contaminating germs. This study used 20 New Zealand rabbits which were divided into four groups (n = 5) depending on the presence or absence of S. aureus and the use of commercial (Palacos®) or EC. A histological method, based on bone architecture damage, was proposed to evaluate from 1 to 9 the histological results and the response of the infected tissue. The macrophage response was also evaluated using monoclonal antibody RAM‐11. The study showed better bone conservation with the use of EC with PLGA microspheres against the Palacos® commercial cement, including the noncontaminated and contaminated groups. © 2019 The Authors.

Abstract
UNLABELLED This study was carried out to determine the time and concentration profile required to achieve vancomycin-mediated eradication of Staphylococcus aureus biofilm. This information is critical for the identification of performance targets for local antibiotic delivery vehicles that target biofilm infections. S. aureus UAMS-1 biofilms were grown for 7 days on titanium-aluminium-niobium discs in Mueller Hinton broth. After 7 days, the discs were then incubated in Mueller Hinton broth containing vancomycin at concentrations of 100, 200, 500, 1,000, and 2,000 mg/L. Biofilm eradication was assessed under both static and shaking conditions. Samples were retrieved at regular intervals for up to 28 days for quantification of residual biofilm. One additional disc was processed per time point for scanning electron microscopy. Progressive and significant reduction of viable bacteria was observed over time at all concentrations compared to unexposed controls. After 28 days under static conditions, the S. aureus biofilm was completely eradicated at 200 mg/L vancomycin and higher concentrations, but not at 100 mg/L. In contrast, bacterial biofilm could not be eradicated under shaking conditions at any concentration. CLINICAL SIGNIFICANCE The present study shows that it is possible to eradicate mature S. aureus biofilm from metal implants by vancomycin alone although the time concentration profile required cannot be achieved by systemic administration or any of the local delivery vehicles currently available. Identifying targets for antibiotic delivery is the first step in developing fit for purpose local antibiotic delivery vehicles that will successfully and predictably treat established biofilm infection. © 2016 Orthopaedic Research Society.

Evaluation of Antibiotics Active against Methicillin-Resistant Staphylococcus aureus Based on Activity in an Established Biofilm. Antimicrob Agents Chemother 2016; 60:5688-94.

Abstract
We used in vitro and in vivo models of catheter-associated biofilm formation to compare the relative activity of antibiotics effective against methicillin-resistant Staphylococcus aureus (MRSA) in the specific context of an established biofilm. The results demonstrated that, under in vitro conditions, daptomycin and ceftaroline exhibited comparable activity relative to each other and greater activity than vancomycin, telavancin, oritavancin, dalbavancin, or tigecycline. This was true when assessed using established biofilms formed by the USA300 methicillin-resistant strain LAC and the USA200 methicillin-sensitive strain UAMS-1. Oxacillin exhibited greater activity against UAMS-1 than LAC, as would be expected, since LAC is an MRSA strain. However, the activity of oxacillin was less than that of daptomycin and ceftaroline even against UAMS-1. Among the lipoglycopeptides, telavancin exhibited the greatest overall activity. Specifically, telavancin exhibited greater activity than oritavancin or dalbavancin when tested against biofilms formed by LAC and was the only lipoglycopeptide capable of reducing the number of viable bacteria below the limit of detection. With biofilms formed by UAMS-1, telavancin and dalbavancin exhibited comparable activity relative to each other and greater activity than oritavancin. Importantly, ceftaroline was the only antibiotic that exhibited greater activity than vancomycin when tested in vivo in a murine model of catheter-associated biofilm formation. These results emphasize the need to consider antibiotics other than vancomycin, most notably, ceftaroline, for the treatment of biofilm-associated S. aureus infections, including by the matrix-based antibiotic delivery methods often employed for local antibiotic delivery in the treatment of these infections.

Abstract
We examined the pharmacokinetic properties of vancomycin conjugated to a bone-targeting agent (BT) with high affinity for hydroxyapatite after systemic intravenous administration. The results confirm enhanced persistence of BT-vancomycin in plasma and enhanced accumulation in bone relative to vancomycin. This suggests that BT-vancomycin may be a potential carrier for the systemic targeted delivery of vancomycin in the treatment of bone infections, potentially reducing the reliance on surgical debridement to achieve the desired therapeutic outcome.

Abstract
Infection in orthopaedic trauma patients is a common problem associated with significant financial and psychosocial costs, and increased morbidity. This review outlines technologies to diagnose and prevent orthopaedic infection, examines implant-related infection and its management, and discusses the treatment of post-traumatic osteomyelitis. The gold standard for diagnosing infection has a number of disadvantages, and thus new technologies to diagnose infection are being explored, including multilocus polymerase chain reaction with electrospray ionization-mass spectrometry and optical imaging. Numerous strategies have been employed to prevent orthopaedic infection, including use of antibiotic-impregnated implant coatings and cement; however, further research is required to optimize these technologies. Biofilm formation on orthopaedic implants is attributed to the glycocalyx-mediated surface mode of bacterial growth and is usually treated through a secondary surgery involving irrigation, debridement and the appropriate use of antibiotics, or complete removal of the infected implant. Research into the treatment of post-traumatic osteomyelitis has focused on developing an optimal local antibiotic delivery vehicle, such as antibiotic-impregnated polymethylmethacrylate (PMMA) cement beads or bioabsorbable bone substitute (BBS) delivery systems. As these new technologies to diagnose, prevent and treat orthopaedic infection advance, the incidence of infection will decrease and patient care will be optimized.

Abstract
Use of antibiotic-loaded bone cements is one of the most effective methods for the prevention and treatment of prosthetic joint infection. However, there is still controversy about the optimal combination and doses of antibiotics that provide the maximum antimicrobial effect without compromising cement properties. In this study, vancomycin and cefazolin were added to a bone cement (Palacos R+G). Antibiotic release, fluid absorption, and mechanical properties were evaluated under physiological conditions. The results show that the type of antibiotic selected has an important impact on cement properties. In this study, groups with cefazolin showed much higher elution than those containing the same concentration of vancomycin. In contrast, groups with cefazolin showed a lower strength than vancomycin groups.

Abstract
OBJECTIVE To evaluate the in vitro antimicrobial activity of the Eucalyptus globulus essential oil, and of the xylitol and papain substances against the following microorganisms: Pseudomonas aeruginosa; Samonella sp.; Staphylococus aureus; Proteus vulgaris; Escherichia coli and Candida albicans. METHOD The in vitro antimicrobial evaluation was used by means of the agar diffusion test and evaluation of the inhibition zone diameter of the tested substances. Chlorhexidine 0.5% was used as control. RESULTS The Eucalyptus globulus oil showed higher inhibition than chlorhexidine when applied to Staphylococcus aureus, and equal inhibition when applied to the following microorganisms: Escherichia coli, Proteus vulgaris and Candida albicans. Papain 10% showed lower antimicrobial effect than chlorhexidine in relation to Candida albicans. Xylitol showed no inhibition of the tested microorganisms. CONCLUSION The Eucalyptus globulus oil has antimicrobial activity against different microorganisms and appears to be a viable alternative as germicidal agent hence, further investigation is recommended.

Abstract
Soluble particulate fillers can be incorporated into antibiotic-loaded acrylic bone cement in an effort to enhance antibiotic elution. Xylitol is a material that shows potential for use as a filler due to its high solubility and potential to inhibit biofilm formation. The objective of this work, therefore, was to investigate the usage of low concentrations of xylitol in a gentamicin-loaded cement. Five different cements were prepared with various xylitol loadings (0, 1, 2.5, 5 or 10 g) per cement unit, and the resulting impact on the mechanical properties, cumulative antibiotic release, biofilm inhibition, and thermal characteristics were quantified. Xylitol significantly increased cement porosity and a sustained increase in gentamicin elution was observed in all samples containing xylitol with a maximum cumulative release of 41.3%. Xylitol had no significant inhibitory effect on biofilm formation. All measured mechanical properties tended to decrease with increasing xylitol concentration; however, these effects were not always significant. Polymerization characteristics were consistent among all groups with no significant differences found. The results from this study indicate that xylitol-modified bone cement may not be appropriate for implant fixation but could be used in instances where sustained, increased antibiotic elution is warranted, such as in cement spacers or beads.

Chitosan coating to enhance the therapeutic efficacy of calcium sulfate-based antibiotic therapy in the treatment of chronic osteomyelitis. J Biomater Appl 2014; 29:514-23.

Abstract
We demonstrate that coating calcium sulfate with deacetylated chitosan enhances the elution profile of daptomycin by prolonging the period during which high concentrations of antibiotic are released. Coatings reduced initial bolus release of daptomycin by a factor of 10 to approximately 1000 µg/ml, and levels remained above 100 µg/ml for up to 10 days. Chitosan-coated and uncoated calcium sulfate implants with and without 15% daptomycin were evaluated in an experimental model of staphylococcal osteomyelitis through bacteriology scores, radiology, histopathology, and Gram staining. Significant reduction in bacteriology scores was observed for implants containing daptomycin and coated with chitosan compared with all the other groups. We confirm that the use of chitosan-coated calcium sulfate beads for local antibiotic delivery can be correlated with an improved therapeutic outcome following surgical debridement in the treatment of chronic osteomyelitis.

[PMID: 23604649 PMCID: PMC3773141 DOI: 10.1007/s11999-013-2988-5] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2012] [Accepted: 04/08/2013] [Indexed: 01/31/2023]
Abstract
BACKGROUND Although bacterial antibiotic resistance is increasing, fewer new antibiotics are being developed to compensate. Localized delivery of synergistic antiseptics and antibiotics with a chitosan sponge device may offer an alternative infection treatment. QUESTIONS/PURPOSES In this pilot study, we asked whether antiseptic and antibiotic combinations provided in vitro synergism against Staphylococcus aureus, whether synergism reduces cell viability, and whether their combination releases drugs at inhibitory levels. METHODS To investigate the pharmacodynamics among three combinations of the antiseptic chlorhexidine digluconate (CHX) with the antibiotics amikacin, daptomycin, and vancomycin (VAN) (n=1), we determined the fractional inhibitory concentration (FIC) index against S aureus Cowan I. The determined synergistic combination of CHX and VAN was evaluated for cell compatibility using NIH/3T3 fibroblasts (n=3) and the drug release profile from a chitosan sponge device (n=5). RESULTS With an FIC index<0.5, the combination of CHX+VAN exhibited synergism against S aureus. CHX concentrations≥3.91 μg/mL resulted in fibroblast viability decrease, whereas the combination of CHX+VAN did not decrease fibroblast viability until their concentrations reached ≥7.81 μg/mL. The CHX and VAN release profile, both individually and in combination, was an initial bolus with no difference between eluate concentrations after Day 5. CONCLUSIONS CHX+VAN combination may be delivered locally by a chitosan sponge that synergistically inhibits S aureus growth. CLINICAL RELEVANCE The use of synergism between combined antibiotic and antiseptics delivered at high local concentrations with an implanted chitosan sponge may provide a useful alternative infection treatment option.
