Antimicrobial peptides (AMP) in biofilm induced orthopaedic device-related infections

Orthopaedic device-related infection (ODRI) represent is one of the most challenging complications to manage in orthopaedic and trauma surgery. Biofilm formation is one of the crucial steps in the development of implant related orthopaedic infections due to the surface-adherent bacteria. Bacterial biofilms have several innate antimicrobial resistance mechanisms and hence difficult to eliminate with conventional antibiotics. Chronic, indolent, unresponsive infection can lead to clinical disability affecting quality of life with socio-economic consequences and compromised patient related health care outcomes. Although there is a basic understanding of the mechanism of biofilm associated antimicrobial resistance, enhanced knowledge, innovative treatment strategies and new therapeutic modalities is the need of the hour to manage biofilm associated Orthopaedic device-related infection (ODRI). Antimicrobial peptides (AMPs) represent an exciting opportunity to treat biofilm infections due to their diverse mechanisms of action. This article highlights the current role and mechanism of Antimicrobial peptides (AMPs) in preventing and eradicating Orthopaedic device-related infection (ODRI).
