REVIEW
Jaiben George, Alison K Klika, Carlos A Higuera
Prosthetic joint infection (PJI) is a serious complication after total joint arthroplasty (TJA). Chlorhexidine is a widely used antiseptic because of its rapid and persistent action. It is well tolerated and available in different formulations at various concentrations. Chlorhexidine can be used for pre-operative skin cleansing, surgical site preparation, hand antisepsis of the surgical team and intra-articular irrigation of infected joints. The optimal intra-articular concentration of chlorhexidine gluconate in irrigation solution is 2%, to provide a persistent decrease in biofilm formation, though cytotoxicity might be an issue...

The aim of this study was to assess the cytotoxicity of chlorhexidine gluconate (CHG) on human blood lymphocytes as a useful ex vivo model for accelerated human toxicity studies. Using biochemical and flow cytometry assessments, we demonstrated that addition of CHG at 1 μM concentration to human blood lymphocytes induced cytotoxicity following 6 h. The CHG-induced cytotoxicity on human blood lymphocytes was associated with intracellular reactive oxygen species generation, mitochondrial membrane potential collapse, lysosomal membrane injury, lipid peroxidation, and depletion of glutathione...

One of the biggest challenges in endodontics is the complete disinfection of root canals. In addition to mechanical preparation, the technique traditionally also involves channel disinfection with other agents such as sodium hypochlorite, hydrogen peroxide, chlorhexidine, or a combination of these. Some bacterial species are particularly resistant to eradication. Using Enterococcus faecalis in this preliminary study, we tested the bactericidal effectiveness of the Fenton reaction and the photo-Fenton reaction using an LED light with a 400-nm wavelength...

PURPOSE: Dressings containing chlorhexidine gluconate (CHG) are increasingly used in clinical environments for prevention of infection at central venous catheter insertion sites. Increased tolerance to this biocide in staphylococci is primarily associated with the presence of qacA/B and smr genes. METHODOLOGY: We used a culture-independent method to assess the prevalence of these genes in 78 DNA specimens recovered from the skin of 43 patients at catheter insertion sites in the arm that were covered with CHG dressings...

Background: Staphylococcus aureus possessing either the smr or qacA/B genes are associated with decreased susceptibility to chlorhexidine gluconate (CHG) and other antiseptics. Previous studies of antiseptic tolerant staphylococci have largely focused on high-risk populations and the exact role of healthcare exposure on acquisition of these organisms is unclear. We sought to describe the risk factors and features of infection caused by antiseptic tolerant S. aureus in a general pediatric population.Methods: Isolates were selected from an ongoing S...

BACKGROUND: Colonized patients are a reservoir for transmission of multidrug-resistant organisms (MDROs). Not many studies have examined the effectiveness of daily chlorhexidine gluconate (CHG) bathing under routine care conditions. We present a descriptive analysis of the trends of MDRO colonization following implementation of daily CHG bathing under routine clinical conditions in an intensive care unit (ICU). METHODS: From May 2010-January 2011, we screened patients admitted to a 24-bed ICU for and methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and fluoroquinolone-resistant gram-negative bacilli (FQRGNB)...

Increasing use of daily chlorhexidine gluconate (CHG) bathing can potentially lead to selection for organisms with reduced susceptibility to CHG, limiting the utility of CHG. We examined reduced susceptibility to CHG of fluoroquinolone-resistant gram-negative bacilli and methicillin-resistant Staphylococcus. No evidence suggested reduced susceptibility to CHG.

A major shortcoming of contemporary dentin adhesives is their limited durability. Exposed collagen fibrils within the bonding interface are degraded by matrix metalloproteinases (MMPs), resulting in aging of the resin-dentin bond. In this study, chlorhexidine-loaded amorphous calcium phosphate (ACP) nanoparticles were synthesized to induce the mineralization of collagen fibrils. The nanoparticles sustainably released chlorhexidine to inhibit MMPs during mineralization. Three types of ACP nanoparticles were prepared: N-ACP containing no chlorhexidine, C-ACP containing chlorhexidine acetate, and G-ACP containing chlorhexidine gluconate, which had a higher drug-loading than C-ACP...
