Long-term catheter-related bloodstream infections (CRBSI) involving coagulase-negative Staphylococci are associated with poor patient outcomes, increased hospitalization and high treatment costs. The use of vancomycin-lock therapy has been an important step forward to treat these biofilms although failures appear in 20% of patients. In this study, we report that a high dose of daptomycin-lock therapy may offer a therapeutic advantage for these CRBSI in just 24 h of treatment.

Klebsiella pneumoniae continues to be an important cause of community-acquired and nosocomial infection. This bacterium can cause catheter related infections by forming biofilm on the surface of catheter. The aim of our study is to determine the in vitro stability and efficacy of colistin, ciprofloxacin, tobramycin, doripenem and tigecycline alone, or in combination with clarithromycin or esomeprazole, as 24-h lock solutions against biofilm-embedded K. pneumoniae strains. The efficacy of antibiotic lock solutions was tested in an in vitro catheter biofilm model against K...

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...

Biofilm bacteria in the Tenckhoff catheter are notoriously difficult to eradicate. They are the potential sources of relapsing or repeat peritonitis among peritoneal dialysis (PD) patients. Inadequate penetration into biofilms by standard intraperitoneal antibiotics, as well as a lack of effective adjunctive treatment, leads to a high rate of Tenckhoff catheter loss as a result of biofilm bacteria. In hemodialysis, on the other hand, catheter-related bloodstream infection caused by biofilm bacteria does not necessarily lead to a loss of catheter...

We report the case of a catheter-related bloodstream infection caused by Chryseobacterium indologenes, an uncommon and multi-resistant pathogen, in a pediatric patient with a long-term vascular access device placed for chemotherapy treatment. The infection was successfully treated with ciprofloxacin antibiotic-lock therapy. This is the first report on successful salvage of a long-term device colonized by multi-resistant Chryseobacterium indologenes.

The use of antibiotic lock solutions as prophylaxis for catheter-associated blood stream infection (CRBSI) has been shown to be effective in previous randomized controlled trials. However, the cost-effectiveness of this approach had not been studied. In 2012, the routine gentamicin-heparin lock solution used in Auckland City Hospital was withdrawn from the market, leading to a change to heparin-only lock. This was then replaced with gentamicin-citrate lock in 2014. This situation allowed review of the CRBSI rate and financial impact of different catheter lock solutions...

For long-term central lines (CL), the lumen is the major source of central line-associated bloodstream infections (CLABSI). The current standard of care for maintaining catheter patency includes flushing the CL with saline or heparin. Neither agent has any antimicrobial activity. Furthermore, heparin may enhance staphylococcal biofilm formation. We evaluated the safety and efficacy of a novel nonantibiotic catheter lock solution for the prevention of CLABSI. Between November 2015 and February 2016, we enrolled 60 patients with hematologic malignancies who had peripherally inserted central catheters (PICC) to receive the study lock solution...

The use of central venous catheters (CVC) is associated with a risk of microbial colonization and subsequent potentially severe infection. Microbial contamination of the catheter leads to the development of a microbial consortia associated with the CVC surface and embedded in an extracellular matrix, named biofilm. This biofilm provides bacterial cells the ability to survive antimicrobial agents and the host immune system and to disseminate to other sites of the body. The best preventive strategy is to avoid any unnecessary catheterization or to reduce indwelling duration when a CVC is required...

Candida albicans frequently causes bloodstream infections; its budded-to-hyphalform transition (BHT) and biofilm formation are major contributors to virulence. During an analysis of antibacterial compounds that inhibit C. albicans BHT, we found that the tetracycline derivative minocycline inhibited BHT and subsequent biofilm formation. Minocycline decreased expression of hypha-specific genes HWP1 and ECE1, and adhesion factor gene ALS3 of C. albicans. In addition, minocycline decreased cell surface hydrophobicity and the extracellular β-glucan level in biofilms...

The prevention of catheter-related blood stream infections (CRBSI) in hemodialysis (HD) patients remains a challenge because of high morbidity and mortality associated to CRBSI. Alternative locking solutions (ALS) containing an antithrombotic substance with additional antimicrobial or antibiofilm properties (citrate, ethylenediaminetetraacetic acid [EDTA], 70% ethanol, thrombolytics) with or without the addition of molecules with specific antimicrobial activity (antibiotics, taurolidine, paraben-methylene-blue) has been proposed with the aim to prevent or eradicate intraluminal biofilm colonization and subsequent CRBSI...

Infection is a common complication and is the second leading cause of death in hemodialysis patients. The risk of bacteremia in hemodialysis patients is 26-fold higher than in the general population, and 1/2-3/4 of the causative organisms of bacteremia in hemodialysis patients are Gram-positive bacteria. The ratio of resistant bacteria in hemodialysis patients compared to the general population is unclear. Several reports have indicated that hemodialysis patients have a higher risk of methicillin-resistant Staphylococcus aureus infection...

Central venous catheters are essential for the treatment of patients with haematological malignancies and the recipients of stem-cell transplant. This patient population is, however, at high risk for catheter-related bloodstream infections that can result in substantial morbidity, mortality, and health-care-associated costs. Efficient prevention, early diagnosis, and effective treatment are essential to providing the best care to these patients. Although confirming the catheter as a source of infection remains challenging, the Infectious Diseases Society of America definition of catheter-related bloodstream infection remains the most precise definition to use in these patients...

BACKGROUND: Central-line-associated blood-stream infection (CLABSI) is a highly consequential nosocomial infection. The most effective management includes the removal of the infected catheter. Retention of the catheter and antibiotic lock therapy (ALT) along with systemic antibiotics may be attempted only if there are unusual extenuating circumstances. CLABSIs due to Gram-negative bacteria (GNB) is more common in our setting and the organisms are often highly resistant. Hence, there is a need to explore the use of novel antimicrobials for catheter lock solutions along with antibiofilm agents...

BACKGROUND: The most appropriate lock solution for central venous access devices is still to be defined. GAVeCeLT - the Italian group for venous access devices - has developed a consensus on the evidence-based criteria for the choice and the clinical use of the most appropriate lock solution for central venous catheters (excluding dialysis catheters). METHOD: After the constitution of a panel of experts, a systematic collection and review of the literature has been performed, focusing on clinical studies dealing with lock solutions used for prevention of occlusion (heparin, citrate, urokinase, recombinant tissue plasminogen activator [r-TPA], normal saline) or for prevention of infection (citrate, ethanol, taurolidine, ethylene-diamine-tetra-acetic acid [EDTA], vancomycin, linezolid and other antibiotics), in both adults and in pediatric patients...
