Treatment of vascular graft infections: gentamicin-coated ePTFE grafts reveals strong antibacterial properties in vitro. JOURNAL OF MATERIALS SCIENCE. MATERIALS IN MEDICINE 2022; 33:30. [PMID: 35267117 PMCID: PMC8913444 DOI: 10.1007/s10856-022-06650-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 01/19/2022] [Indexed: 06/14/2023]
Abstract
Vascular graft infections (VGI) are severe complications in prosthetic vascular surgery with an incidence ranging from 1 to 6%. In these cases, synthetic grafts are commonly used in combination with antimicrobial agents. Expanded polytetrafluoroethylene (ePTFE) is in clinical use as a synthetic graft material and shows promising results by influencing bacterial adhesion. However, the literature on antibiotic-bound ePTFE grafts is scarce. Gentamicin is a frequently used antibiotic for local treatment of surgical site infections, but has not been evaluated as antimicrobial agent on ePTFE grafts. In this study, we examine the antimicrobial efficacy and biocompatibility of novel types of gentamicin-coated ePTFE grafts in vitro. ePTFE grafts coated with gentamicin salt formulations with covalently-bound palmitate were evaluated in two drug concentrations (GP1.75% and GP3.5%). To investigate effects from types of formulations, also suspensions of gentamicin in palmitate as well as polylactide were used at comparable levels (GS + PA and GS + R203). Antibacterial efficacies were estimated by employing a zone of inhibition, growth inhibition and bacterial adhesion assay against Staphylococcus aureus (SA). Cytotoxicity was determined with murine fibroblasts according to the ISO standard 10993-5. Gentamicin-coated ePTFE grafts show low bacterial adherence and strong antibacterial properties in vitro against SA. Bactericidal inhibition lasted until day 11. Highest biocompatibility was achieved using gentamicin palmitate GP1.75% coated ePTFE grafts. ePTFE grafts with gentamicin-coating are effective in vitro against SA growth and adherence. Most promising results regarding antimicrobial properties and biocompatibility were shown with chemically bounded gentamicin palmitate GP1.75% coatings. Graphical abstract.

Polycatecholamine and gentamicin as modifiers for antibacterial and blood-biocompatible polyester vascular prostheses. MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2022; 133:112645. [PMID: 35034823 DOI: 10.1016/j.msec.2022.112645] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 12/05/2021] [Accepted: 01/02/2022] [Indexed: 11/15/2022]
Abstract
Polyester (PET) prostheses are commonly used in reconstructive vascular surgery. The most serious complication after implantation is early or late infection of the graft. Therefore, there is high demand to protect prosthesis against bacterial adhesion and biofilm development. For this reason, in this work PET prostheses were first coated by highly adhesive polycatecholamine layer. The grafts were then coupled with gentamicin and studied in relation to morphological and structural properties, biological safety (contact with blood, reaction of vascular endothelial cells (HUVEC), Danio rerio fish), drug release and antibacterial activity. Among two tested catecholamine monomers, L-DOPA was found to be more effective precursor in this process than dopamine. For L-DOPA, assistance of Cu2+, Mg2+ and Na+ ions seems to increase the amount of further immobilized drug. Coated prostheses exhibited greater human endothelial cell proliferation increase and lower cytotoxic effect than uncoated. The modification reduced the hemolysis observed for pristine commercial graft and limited the rate of abnormalities in D. rerio larvae, confirming the safety of the proposed modification. The coating allowed to double the amount of immobilized antibiotic in comparison with uncoated graft which resulted in increased antibacterial activity and reduced bacterial adhesion against 4 bacterial strains prevalent in biomaterials infections. Overall, poly(L-DOPA)-coatings deposited on PET vascular grafts can effectively functionalize these prostheses for higher safety in biomedical applications.

Abstract
OBJECTIVE Vascular graft infection (VGI) remains an important complication with a high mortality and morbidity rate. Currently, studies focusing on the role of vascular graft coatings in the prevention of VGI are scarce. Therefore, the aims of this study were to survey and summarise key features of pre-clinical in vivo models that have been used to investigate coating strategies to prevent VGI and to set up an ideal model that can be used in future preclinical research. DATA SOURCES A systematic review was conducted in accordance with the Preferred reporting items for Systematic Reviews and Meta-Analysis guidelines. A comprehensive search was performed in MEDLINE (PubMed), Embase, and Web of Science. REVIEW METHODS For each database, a specific search strategy was developed. Quality was assessed with the Toxicological data Reliability Assessment Tool (ToxRTool). The type of animal model, graft, coating, and pathogen were summarised. The outcome assessment in each study was evaluated. RESULTS In total, 4 667 studies were identified, of which 94 papers focusing on in vivo testing were included. Staphylococcus aureus was the organism most used (n = 65; 67.7%). Most of the graft types were polyester grafts. Rifampicin was the most frequently used antibiotic coating (n = 43, 48.3%). In the outcome assessment, most studies mentioned colony forming unit count (n = 88; 91.7%) and clinical outcome (n = 72; 75%). According to the ToxRTool, 21 (22.3%, n = 21/94) studies were considered to be not reliable. CONCLUSION Currently published in vivo models are very miscellaneous. More attention should be paid to the methodology of these pre-clinical reports when transferring novel graft coatings into clinical practice. Variables used in pre-clinical reports (bacterial strain, duration of activity coating) do not correspond well to current clinical studies. Based on the results of this review, a proposal for a complete and comprehensive set up for pre-clinical invivo testing of anti-infectious properties of vascular graft coatings was defined.

Abstract
Analysed herein are the results of treating a total of 17 patients presenting with pathology of the aorta and lower-limb arteries, who from 2010 to 2018 required redo interventions due to infection of a previously implanted synthetic vascular graft. At admission, 3 patients were diagnosed as having an open infected wound, 11 were found to have a fistula, 2 had a false aneurysm in the area of the distal anastomosis of the branch of the bifurcation aortofemoral prosthesis, and 1 had thrombosis of the branch of the prosthesis with evidence of infection. As redo surgery, 4 patients underwent subclavian-femoral bypass grafting, 2 were subjected to crossover iliac-femoral bypass grafting, 8 to unilateral iliac-femoral bypass grafting, 3 to loop endarterectomy. In the majority of cases (14 of the 17) we used bypass grafting with creation of the tunnel through the muscular lacuna. Lethal outcomes were registered in 35% (n=6) of cases in the early postoperative period. Death was caused by acute renal failure in 6% (n=1), by acute mesenteric thrombosis in 12% (n=2), by gastrointestinal haemorrhage in 6% (n=1), and by multiple organ failure in 12% (n=2). Long-term mortality amounted to 33% (n=3) within 12 months. The main causes of death were increasing renal failure in 10% (n=1) and cardiovascular insufficiency on the background of heart diseases in 10% (n=1), as well as respiratory insufficiency in 10% (n=1). Reinfection in the remote period was diagnosed in 1 patient. A conclusion was drawn that bypass grafting is traumatic, however, it may be the only way to save the limb or patient's life in a complicated clinical situation. Using the superficial femoral vein as a shunt demonstrated good long-term results as to patency and resistance to surgical infection. Using a flap of the greater omentum, retroperitoneal fat, as well as wrapping of the prosthesis with a muscular flap ensured good tolerance of the zone of bypass grafting to reinfection.

Abstract
Prosthetic vascular graft infections of the thoracic aorta are rare but can be fatal. Our comparison of collagen- and gelatin-coated grafts showed that collagen-coated grafts were associated with increased biofilm formation and bacterial adherence in vitro and with higher rates of perioperative vascular graft infections in vivo.

Abstract
Vascular graft infection is a devastating complication of vascular reconstructive surgery. The infection can occur early in the postoperative period and is largely due to intraoperative contamination or by contiguous extension from a nearby infection. It can also occur years after implantation. Staphylococci remain the most common organisms and biofilm production makes eradication difficult. Factors commonly reported to predispose to vascular graft infection are periodontal disease, nasal colonization with Staphylococcus aureus, bacteremia, certain graft characteristics, diabetes mellitus, postoperative hyperglycemia, location of the incision, wound infection, and emergency procedure. Management consists of antibiotic and surgical therapy. Preventive methods are described.

Abstract
The development of new methods for drug elution of graft material, biofiber films and resurfacing of prosthetic graft surfaces offers new opportunities for improvement of graft function in arteriovenous (AV) access. Three areas of research include developing grafts that reduce the development of neointimal hyperplasia, reducing infection and reducing thrombogenicity. The only drug eluting graft presently being used, is the heparin coated expanded polytetrafluoroethylene (ePTFE) graft, which has been shown to decrease the incidence of early thrombosis. New drug eluting grafts include those with paclitaxel and those with antibiotics. The development of a hybrid coated prosthetic graft that can deliver targeted gene therapies holds great promise in the field.
