| description | To be faced with an infected bone defect and the need to accelerate bone union while controlling infection is a welcome challenge for orthopedists. Platelet-rich plasma (PRP) has been applied in tissue defects given their composition of growth factors however the weak antibacterial effects have limited the use of PRP in the clinical setting. Therefore, the aim of this study was to explore the feasibility of using PRP in a local antibiotic delivery system (PADS) with the characteristics of promoting wound healing of bone infection. PADS was prepared with the addition of antibiotics or no antibiotics as control after PRP was prepared by a two-step centrifugation procedure. Antibacterial tests showed zones of inhibition produced by antibiotics were not significantly different with antibiotics combined with PRP. HPLC analysis demonstrated that about 60% of the total vancomycin (VAN) and ceftazidime (CAZ) dose were released within 10 min, then the release rate gradually decreased. However, 90% clindamycin was released within 10 min. Interestingly, above 10 times the minimum inhibitory concentration was presented after 72 h. Additionally, ELISA and morphology studies of PADS indicated that loaded antibiotics could reduce the PRP-released growth factor concentration and disturb the structure of platelet-fibrin beams and fibrin network in a dose-dependent manner. Fortunately, the lower dose of antibiotics maintained their anti-microbial effect, meanwhile growth factors released from PADS, the structure of platelet-fibrin beams, fibrin network remained unaffected. In addition, a patient experiencing infected bone defect receiving this PADS treatment achieved union within the 15-month follow-up. Therefore, this novel PADS approach might represent a potential therapy for patients who have sustained infected bone defects. |
