Ethanol-based lock therapy (LT) solutions are used as an alternative to antibiotics for the conservative management of catheter-related bloodstream infection. However, no clear consensus on regimen or dose has been reached. Our objective was to find the ethanol-based lock solution containing a sufficiently low concentration of ethanol for reduction of the metabolic activity of bacterial and fungal biofilms. Using an in vitro model, we tested 3 concentrations of ethanol (25%-40%-70%), with and without 60 IU of heparin, at 6 different time points and against 24-hour preformed biofilms of Staphylococcus aureus ATCC29213, Staphylococcus epidermidis (clinical isolate), Enterococcus faecalis ATCC33186, Candida albicans ATCC14058, and Escherichia coli ATCC25922...

INTRODUCTION: Catheter-related bloodstream infection (C-RBSI) can sometimes be managed without catheter removal by combining systemic therapy with catheter lock therapy. Most antiseptic lock solutions are made up of ethanol combined with an anticoagulant. However, data regarding the anti-biofilm activity of ethanol combined with enoxaparin are scarce. We aimed to assess the efficacy of ethanol at different concentrations combined with enoxaparin 60IU as a lock solution for eradication of the biofilm of different microorganisms...

BACKGROUND & AIMS: Ethanol lock therapy (ELT) has been shown to reduce the rate of catheter-related bloodstream infection (CRBSI) in high-risk home parenteral nutrition (HPN) patients. The aim of this study was to determine whether ELT therapy for all patients newly started on HPN would reduce the incidence of CRBSI. METHODS: This study was a prospective, double-blind, randomized controlled trial that was carried out from July 2014 to April 2016. The study participants were patients newly started on HPN, and they were randomly assigned to either treatment with ELT or our current standard of care with saline heparin locks...

PURPOSE OF REVIEW: Central venous catheters (CVCs) have a prominent role in the diagnostic and therapy of neonates and children. Herein, we describe the multiple indications for CVC use and the different devices available for central venous access. Given the prevalent use of CVCs, healthcare systems are focused on reducing complications from their use, particularly central line-associated bloodstream infections (CLABSIs). The most up-to-date information available sheds light on best practices and future areas of investigation...

Kocuria kristinae is a catalase-positive, coagulase-negative, Gram-positive coccus found in the environment and in normal skin and mucosa in humans; however, it is rarely isolated from clinical specimens and is considered a nonpathogenic bacterium. We describe a case of catheter-related bacteremia due to K. kristinae in a young adult with propionic acidemia undergoing periodic hemodialysis. The patient had a central venous catheter implanted for total parenteral nutrition approximately 6 months prior to the onset of symptoms because of repeated acute pancreatitis...

Patients with intestinal failure have an increased risk for catheter-related bloodstream infections that can necessitate central venous line replacement and result in morbidity, prolonged hospitalization, or mortality. For pediatric patients with intestinal failure, the severe loss of intestinal absorptive ability leads to reliance on parenteral nutrition to meet minimal needs required for growth and development. Reliance on parenteral nutrition, in turn, forces dependency on central venous lines. Recent research concentrating on the pediatric population with intestinal failure indicates that prophylactic ethanol lock therapy can reduce the rate of catheter-related bloodstream infections and decrease central venous line removal rates in this high-risk population...

Candida albicans is a major cause of catheter-related bloodstream infections and is associated with high morbidity and mortality. Due to the propensity of C. albicans to form drug-resistant biofilms, the current standard of care includes catheter removal; however, reinsertion may be technically challenging or risky. Prolonged exposure of an antifungal lock solution within the catheter in conjunction with systemic therapy has been experimentally attempted for catheter salvage. Previously, we demonstrated excellent in vitro activity of micafungin, ethanol, and high-dose doxycycline as single agents for prevention and treatment of C...

In cancer patients with long-term central venous catheters (CVC), removal and reinsertion of a new CVC at a different site might be difficult because of the unavailability of accessible vascular sites. In vitro and animal studies showed that a minocycline-EDTA-ethanol (M-EDTA-EtOH) lock solution may eradicate microbial organisms in biofilms, hence enabling the treatment of central line-associated bloodstream infections (CLABSI) while retaining the catheter in situ Between April 2013 and July 2014, we enrolled 30 patients with CLABSI in a prospective study and compared them to a historical group of 60 patients with CLABSI who had their CVC removed and a new CVC inserted...

Infection of intravascular catheters by Staphylococcus aureus is a significant risk factor within the health care setting. To treat these infections and attempt salvage of an intravascular catheter, antimicrobial lock solutions (ALSs) are being increasingly used. However, the most effective ALSs against these biofilm-mediated infections have yet to be determined, and clinical practice varies greatly. The purpose of this study was to evaluate and compare the efficacies of antibiotics and antiseptics in current clinical use against biofilms produced by reference and clinical isolates of S...

Natural deep eutectic solvents (NADES) are a novel class of eutectics which show a unique potential as solubilizer of water insoluble compounds. The purpose of the current study was to evaluate the potential of NADES as a solvent for the hydrophobic photosensitizer curcumin for use in antimicrobial photodynamic therapy (aPDT). Two of the seventeen NADES initially prepared (i.e., NADES GS and MC3) solubilized >0.05mg/ml curcumin and were further characterized. The hydrolytic stability (i.e., t1/2) of curcumin in NADES was comparable to or up to 2-10 times higher than previously reported results in cyclodextrins and up to >1300 times higher than results reported in buffer at pH8...

We report the use of ethanol lock therapy to dramatically reduce the incidence of catheter-related bloodstream infections (CRBSIs) in a long-term adult home parenteral nutrition (HPN) patient. This case study demonstrates the efficacy of ethanol lock therapy in eliminating CRBSIs when other treatments have been unsuccessful. We suggest that ethanol lock therapy has an important role in decreasing CRBSI in HPN patients with recurrent CRBSIs.
