Ethanol lock therapy

BACKGROUND: Central venous catheter (CVC) use is commonplace in cancer patients. Antimicrobial lock therapy (ALT), the instillation of a concentrated antimicrobial solution into the catheter lumen, is one method for preventing infection among CVCs. This systematic review discusses the effectiveness and safety of prophylactic ALT in cancer patients with CVCs. METHODS: A literature search was performed using the Medline database and Google Scholar from inception until April 2016...

BACKGROUND: Ethanol lock therapy (ELT) with systemic antimicrobial therapy is a promising therapy for catheter-related infection (CRI). The impact of ELT timing on treatment efficacy and costs is unknown. PROCEDURES: A prospective study was conducted in the Hematology/Oncology Unit at the Children's Hospital of Michigan. Patients with suspected CRI were randomized to Preemptive ELT arm or Rescue ELT arm after positive culture. RESULTS: Five cases in Preemptive arm and 9 in Rescue arm had a confirmed CRI...

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...

PURPOSE: Children with intestinal failure (IF) requiring central venous catheters (CVCs) often experience frequent catheter-related bloodstream infections (CRBSIs), which is a serious and life-threatening complication. To reduce the incidence of CRBSI, prophylactic ethanol lock therapy (ELT) was initiated. METHODS: Patients with IF received home parenteral nutrition via a silicone tunneled CVC. All of them had received therapeutic ELT from January 2009 (first period) and prophylactic ELT from December 2012 (second period)...

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...

BACKGROUND: Catheter malfunction, including thrombosis, is associated with reduced dialysis adequacy, as well as an increased risk of catheter-related bacteraemia and mortality. The role of anticoagulants in the prevention of catheter malfunction remains uncertain. OBJECTIVES: This review aimed to compare the prophylactic effect of different anticoagulant agents, preparations, doses and administration on the incidence of central venous haemodialysis catheter-related malfunction and sepsis in patients with end-stage kidney disease (ESKD)...

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...

BACKGROUND: Prophylactic ethanol lock therapy (ELT) reduces central line-associated bloodstream infections (CLA-BSIs) in children with intestinal failure (IF). However, the risk of associated complications is unclear. We aim to describe our experience with prophylactic ethanol locks in a cohort of patients with IF. MATERIALS AND METHODS: Thirty patients on ELT from 2010-2013 were identified by review of our intestinal rehabilitation registry. Patient demographics, CLA-BSI events, and line complications were extracted...

BACKGROUND: Intravascular catheter salvage may be attempted in clinically suitable cases in pediatric patients with catheter-related bloodstream infections. The purpose of this study was to assess the effectiveness of ethanol and hydrochloric acid (HCl) locks in achieving catheter salvage through decision-analysis modeling. METHODS: A Markov decision model was created to simulate catheter salvage using three management strategies: systemic antibiotics alone, antibiotics plus HCl lock, and antibiotics plus ethanol lock...

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...

INTRODUCTION: Catheter-related bloodstream infection (CRBSI) is a serious complication in patients receiving home parenteral nutrition (HPN). Antibiotic lock therapy (ALT) and ethanol lock therapy (ELT) can be used to prevent CRBSI episodes in high-risk patients. METHODS: Following institutional review board approval, all patients enrolled in the Mayo Clinic HPN program from January 1, 2006, to December 31, 2013, with catheter locking were eligible to be included...

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.

Bacterial overgrowth in the inner layer of the catheter as a biofilm is highly encountered in routine medical care, and it may occur in a few days after inserting a catheter as an access in hemodialysis (HD) patients. Catheter-induced bacteremia is often due to the development of biofilms. Locking catheters with antimicrobial agents is an effective way of reducing the risk of catheter-related infection. In a controlled, randomized clinical trial, 64 chronic HD patients (32 men and 32 women with a mean age of 57...

BACKGROUND: Serial transverse enteroplasty (STEP) lengthens and tapers dilated small bowel in patients with short bowel syndrome (SBS). Previous reports document encouraging outcomes with regard to tolerance for enteral nutrition (EN) and complications appear related to the re-operative nature of many cases and to the presence of multiple staple lines. However, infectious complications following STEP have not been examined. Since infections, especially catheter-related blood stream infections (CRBSI), are considered detrimental in infants and children with SBS, we sought to define the frequency and outcomes of peri-operative infections associated with STEP...

RATIONALE: Ethanol rapidly eradicated experimental biofilm. Clinical studies of ethanol lock to prevent catheter-related infections (CRIs) suggest preventive efficacy. No such studies have been done in intensive care units (ICU). OBJECTIVES: To determine whether ethanol lock decreases the risk of major CRI in patients with short-term dialysis catheters (DCs). METHODS: A randomized, double-blind, placebo-controlled trial was performed in 16 ICUs in seven university hospitals and one general hospital in France between June 2009 and December 2011...
