Colonization and infection Cvc

Marie Gominet, Fabrice Compain, Christophe Beloin, David Lebeaux
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...

Biofilm forming capacity of yeasts colonizing the intravenous devices is considered a key factor involved in the pathogenesis of Candida catheter-related bloodstream infections (CCRBSI). The biofilm production of strains of Candida spp. isolated both from the CVC and from the blood of patients with CCRBSI was compared to that of strains isolated from patients not having CCRBSI. Results, expressed in terms of Biofilm Index (BI), revealed that biofilm-producing strains were isolated in the CCRBSI group with a frequency significantly higher than in the non-CCRBSI group (χ(2) = 4...

BACKGROUND: Superficial culture has a high negative predictive value in the assessment of catheter tip colonization (CC) and catheter-related bloodstream infection (C-RBSI). However, the process of hub culture requires the hubs to be swabbed, and this carries a risk of dislodging the biofilm. At present, most catheter hubs are closed by needleless connectors (NCs) that are periodically replaced. Our objective was to compare the yield of SC (skin + hub culture) with that of skin + NC culture in the assessment of CC and C-RBSI...

PURPOSE: Catheter-related bloodstream infections affect patients in surgical and intensive care settings worldwide, causing complications, aggravation of existing symptoms and increased length of stay. The trial aimed at comparing two registered skin antiseptics with respect to their residual and therefore infection-preventing effects. METHODS: In a parallel, monocentric, prospective, triple-blind, randomized trial the difference in bacterial recolonization of catheter skin sites in central venous (CVC) and epidural catheters (EC) was investigated by comparing two alcoholic-based skin disinfectants...

BACKGROUND: The central venous catheter (CVC) is essential in managing acutely ill patients in hospitals. Bloodstream infection is a major complication in patients with a CVC. Several infection control measures have been developed to reduce bloodstream infections, one of which is impregnation of CVCs with various forms of antimicrobials (either with an antiseptic or with antibiotics). This review was originally published in June 2013 and updated in 2016. OBJECTIVES: Our main objective was to assess the effectiveness of antimicrobial impregnation, coating or bonding on CVCs in reducing clinically-diagnosed sepsis, catheter-related blood stream infection (CRBSI), all-cause mortality, catheter colonization and other catheter-related infections in adult participants who required central venous catheterization, along with their safety and cost effectiveness where data were available...

Permanent central venous catheters (CVC), such as Port-a-Cath®, Hickmann® or PICC®, are widely used in oncology patients for cancer treatment. Thrombosis is a frequent complication that should be ruled out, as it is associated with potentially severe infection and hemodynamic consequences. This is the case report of a male patient who was undergoing chemotherapy for colon cancer. The patient presented with an atrial mass secondary to a CVC-related organized thrombus located inside the atrial cavity. The mass was inducing a massive right-to-left intracardial shunt due to a persistent foramen ovale and signs of respiratory failure that required surgical intervention to remove the intracardial mass...

BACKGROUND: Layouts of biomedical devices were tightly related with the emergence of Staphylococcus epidermidis as a major cause of nosocomial infections because of its ability to form biofilm on the biomaterial surfaces. This fact led researchers to develop in-vitro models to simulate what is really happening during biofilm formation process in order to have a better understanding of this phenomena and then to control it and to resolve the associated problems. The aim of this paper was to develop a homemade dynamic device based on instruments used in clinical practice, easy to mount, with low coast and with no sophisticated features...

PURPOSE: The intestinal failure (IF) population is dependent upon central venous catheters (CVC) to maintain minimal energy requirements for growth. Central venous catheter infections (CVCI) are frequent and an independent predictor of intestinal failure associated liver disease. A common complication in children with long-term CVC is the risk of line breakage. Given the often-limited usable vascular access sites in this population, it has been the standard of practice to perform repair of the broken line...

BACKGROUND: Catheter-related bloodstream infections (CRBSIs) are currently detected in patients with clinically suspicion. The aim of our study was to evaluate whether CRBSIs could be anticipated and detected in a subclinical stage by peptide nucleic acid fluorescence in situ hybridization (PNA FISH) using universal hybridization probes or acridine orange leucocyte cytospin (AOLC) tests in haematooncological patients with central venous catheters (CVCs) in situ. MATERIALS AND METHODS: Peptide nucleic acid fluorescence in situ hybridization and AOLC tests using blood samples from one CVC lumen/port chamber in haematooncological patients were continuously performed...

BACKGROUND: Catheter-related bloodstream infections (CRBSIs) and catheter-related thrombosis (CRT) are common complications of central venous catheters (CVC), which are used to monitor patient health and deliver medications. CVCs are subject to protein adsorption and platelet adhesion as well as colonization by the natural skin flora (i.e. Staphylococcus aureus and Staphylococcus epidermidis). Antimicrobial and antithrombotic drugs can prevent infections and thrombosis-related complications, but have associated resistance and safety risks...

Non-tuberculous mycobacteria (NTM) are acid-fast bacteria that are ubiquitous in the environment and can colonize soil, dust particles, water sources, and food supplies. They are divided into rapidly growing mycobacteria such as Mycobacterium fortuitum, Mycobacterium chelonae, and Mycobacterium abscessus as well as slowly growing species such as Mycobacterium avium, Mycobacterium kansasii, and Mycobacterium marinum. About 160 different species, which can cause community acquired and health care-associated infections, have been identified...

BACKGROUND AND OBJECTIVES: Nosocomial catheter related bloodstream infections (CR-BSI) increase morbidity and mortality in critically ill patients. Central venous catheters (CVC) coated with rifampin and minocycline (RM) decrease rates of colonization and CR-BSI. However, recent trials challenged the clinical impact of such catheters. We designed this trial to compare rates of colonization and CR-BSI in RM catheters and controls in a cohort of critically ill patients in Brazil. METHODS: Prospective, controlled trial conducted in one medico-surgical ICU...
