HIGHLIGHTS 2% taurolidine catheter lock solution without additives is safe and efficient. CRBSI and dysfunction rates compare favorably against other studies in hemodialysis Background: In hemodialysis patients, catheter-related bloodstream infection (CRBSI) and catheter dysfunction are common and cause significant morbidity, mortality, and costs. Catheter lock solutions reduce CRBSI and catheter dysfunction rates, but solutions containing heparin, citrate, or antibiotics are associated with adverse effects. Due to its antimicrobial and antithrombotic properties and benign safety profile, taurolidine is suitable for use in catheter lock solutions. In this study the effectiveness and safety of a catheter lock solution containing 2% taurolidine without citrate or heparin (TauroSept®, Geistlich Pharma AG, Wolhusen, Switzerland) in hemodialysis patients were investigated for the first time. Methods: Data from 21 patients receiving chronic hemodialysis via tunneled central venous catheters with 2% taurolidine solution as a catheter lock were analyzed in a single-center retrospective study and compared with the existing literature in a review. The primary endpoint was CRBSI rate. Secondary endpoints included catheter dysfunction, treatment, and costs; catheter technical problems, resolution, and costs; and adverse events. Data were compared to outcomes with standard lock solutions in the literature. Results: No CRBSIs occurred during the observation period of 5,639 catheter days. The catheter dysfunction rate was 0.71 per 1,000 catheter days, and the catheter dysfunction treatment costs were CHF (Swiss Franc) 543 per patient. No technical problems or adverse events related to the use of 2% taurolidine-containing catheter lock solution were observed. These results compare favorably with other catheter lock solutions. Conclusions: A solution containing 2% taurolidine seems suitable as a hemodialysis catheter lock. In a Swiss cohort, it prevented CRBSI, limited catheter dysfunction, and was cost-efficient.

Whilst antibiotic lock is effective to eradicate biofilm bacteria on hemodialysis catheters, this adjunctive method has scarcely been tested in peritoneal dialysis (PD) patients. After our previous successful experience of its use to salvage two Tenckhoff catheters, we encountered another patient with problematic biofilm-associated PD peritonitis who strongly refused catheter removal. As a result, antibiotic lock was given once daily, initially, with continuation of the usual PD schedule. However, relapsing peritonitis could not be prevented until we administered antibiotic lock without dialysate in the abdomen, which led to successful eradication of biofilm bacteria. To investigate the significance of having “dry abdomen” during antibiotic lock treatment, we injected an equivalent amount of contrast into the Tenckhoff catheter under fluoroscopy. We observed that the catheter lock solution could be retained over a long period of time only with “dry abdomen,” whereas rapid dissipation of the lock solution occurred in the presence of dialysate. We concluded that whilst antibiotic lock in a once-daily regimen can be highly effective against biofilm bacteria on a Tenckhoff catheter, it is essential to withhold PD exchanges during the dwell of antibiotic lock to prevent it from dissolving into the surrounding dialysate.

Objective.To examine the mechanical integrity of hemodialysis catheters after exposure to the combination of N-acetylcysteine, ti-gecycline, and heparin, compared with that of catheters exposed to heparin alone.Methods.We used 3 types of hemodialysis catheters: polyurethane, silicone, and carbothane catheters. Catheter segments were incubated in vitro for various time intervals of up to 2 weeks either in a novel catheter lock solution (novel CLS), which consisted of N-acetylcysteine, tigecycline, and heparin, or in heparin alone (as a control). At the time of testing, each segment was rinsed and cut longitudinally into 2 sections. All catheter sections were scanned using an optical dissecting microscope to check for surface abnormalities and to measure wall thickness. We also carried out tensile strength testing of another set of catheters using a universal testing machine. Tested parameters included stress at yield, strain at yield, stress at break, strain at break, modulus of elasticity, and force at break.Results.The surfaces of catheters in both groups appeared similar by microscopy. The mean thickness of the catheter wall was not significantly different for the catheters exposed to the novel CLS and the catheters exposed to heparin (P >.05). Results for most of the tensile strength parameters tested were similar in the 2 groups of catheters at the end of 2 weeks of incubation. In particular, the force-at-break value of all tested catheters remained much greater than that recommended by industry standards.Conclusions.The use of the novel catheter lock solution did not impair the mechanical integrity or increase the propensity for fracture of hemodialysis catheters.

ABSTRACT Candida auris is an emerging pathogen that can cause virulent central-line-associated bloodstream infections. Catheter salvage through the eradication of biofilms is a desirable therapeutic option. We compared taurolidine and minocycline-EDTA-ethanol (MEE) catheter lock solutions in vitro for the eradication of biofilms of 10 C. auris strains. MEE fully eradicated all C. auris biofilms, while taurolidine lock partially eradicated all of the C. auris biofilms. The superiority was significant for all C. auris strains tested (P = 0.002).
