Ethanol combined with heparin as a locking solution for the prevention of catheter related blood stream infections in hemodialysis patients: A prospective randomized study.

Introduction: Ethanol lock solution has been mainly administered in paediatric and home parenteral nutrition patients in order to prevent catheter related blood stream infections (CRBSI). Its utility in hemodialysis (HD) patients with non-tunneled-uncuffed catheter (NTC) has been poorly explored.

Methods: We conducted a prospective randomized study in chronic HD patients requiring a newly inserted NTC-while awaiting for the maturation of an already established arteriovenous fistula (AVF) or arteriovenous graft (AVG) or tunneled-cuffed catheter insertion.

Strong correlation of B2-microglobulin (B2-m) with procalcitonin (PCT) in the serum of chronic hemodialysis patients: a role for infections in the dialysis-related amyloidosis?

Introduction: Infections trigger the activation of defensive cells capable to produce and release B(2)-microglobulin (B(2)-m). Procalcitonin (PCT), secreted by a wide range of human cells, included the aforementioned defensive cells, is generally considered a sensitive and specific marker of infection. In this prospective study, we examined the possibility that infections, as detected by increased levels of PCT, increase the serum levels of B(2)-m in chronic hemodialysis (CHD) patients, possibly affecting the rate of progression of dialysis-related amyloidosis (DRA).

Dissemination of vancomycin-resistant enterococci among haemodialysis patients in Athens, Greece.

Objectives: Vancomycin-resistant enterococci (VRE) may colonize haemodialysis patients, but their epidemiology in this population is not well defined. Within the few last years, VRE strains have emerged and are increasingly isolated in the nosocomial environment in Greece, but colonization of dialysis patients has never been evaluated before. This study sought to determine the epidemiology of VRE colonization within this high-risk population and define the risk factors.

Axillary to saphenous vein bypass for treatment of central venous obstruction in patients receiving dialysis.

Objective: Venous hypertension due to subclavian or innominate vein stenosis coexisting with a functioning arteriovenous access in the ipsilateral arm is a complex problem in patients undergoing hemodialysis. Therapeutic solutions must optimally relieve symptoms, permit use of the angioaccess, and carry minimal surgical risk. The purpose of this study was to evaluate a simple surgical option, bypassing central venous obstruction to the great saphenous vein.
