AI Article Synopsis
- The rise in implant-associated infections (IAIs) continues despite improvements in materials and surgical methods, primarily due to microbes adhering and forming biofilms on implants.
- This study critically evaluates the effectiveness of chitosan-based coatings in preventing IAIs, using a systematic review methodology to analyze forty relevant studies.
- The results show that combining chitosan with enzymes, antimicrobial peptides, and polymers enhances its antimicrobial properties and creates better coatings that are biocompatible and durable for medical implants.
Article Abstract
Despite the advancements in material science and surgical techniques, the incidence of implant-associated infections (IAIs) has increased significantly. IAIs are mainly caused by microbial adhesion and biofilm formation on implant surfaces. In this study, we aimed to evaluate and critically discuss the antimicrobial efficacy of chitosan-based coatings to prevent the occurrence of IAIs. For this purpose, a PRISMA-oriented systematic review was conducted based on predefined criteria and forty studies were selected for qualitative analysis. Results indicated that chitosan (CS) association with enzymes and antimicrobial peptides improves its antimicrobial activity and extends its use in a broad range of physiological conditions. Likewise, CS association with polymers resulted in enhanced antimicrobial and anti-adhesive coatings with desirable properties, such as biocompatibility and durability, for implantable medical devices (IMDs). These findings can assist researchers in the design of new CS coatings for application in IMDs.
