          Peritonitis remains a primary challenge for the long-term success of peritoneal dialysis (PD) technique and one of the main reasons for catheter removal. Prevention and treatment of catheter-related infections are major concerns to avoid peritonitis. The use of taurolidine catheter-locking solution to avoid the development of a biofilm in the catheter’s lumen has obtained good results in hemodialysis catheters for reducing infection rates, although there is scarce literature available regarding its utility in PD. We describe the case of a woman in her 60s who developed relapsing peritonitis due to Pseudomonas aeruginosa, with no possibility of removing peritoneal dialysis catheter because she was not a suitable candidate for hemodialysis. After the fourth peritonitis episode caused by Pseudomonas species, the use of taurolidine catheter-locking solution was initiated. She received a total of 9 doses, with a favorable microbiological and clinical outcome and no further relapses more than 10 months after taurolidine PD catheter lock treatment was started. We report the successful elimination of an aggressive bacteria after taurolidine PD catheter lock use, with no relevant adverse events.

          Prevention of dialysis catheter-related sepsis with a citrate-taurolidine-containing lock solution.

          The use of haemodialysis catheters is complicated by catheter-related sepsis. Intraluminal colonization of the catheter with bacteria is important in the pathogenesis of catheter-related sepsis. The use of a catheter lock solution containing the antimicrobial taurolidine might prevent bacterial colonization, thereby reducing the incidence of catheter-related sepsis. In a randomized prospective trial, patients receiving a dialysis catheter were included and catheters were locked with either heparin or a citrate-taurolidine-containing solution. Blood cultures drawn from the catheter lumen were routinely taken every 2 weeks and at time of removal of the catheter to detect bacterial colonization. Catheter-related sepsis and exit-site infections were registered for both groups. A total of 76 catheters were inserted in 58 patients. The incidence of catheter colonization progressed slowly over time with no differences between dialysis catheters filled with heparin or citrate-taurolidine-containing solution. The number of exit-site infections was also similar between both groups. In the heparin group, four cases of catheter-related sepsis occurred as opposed to no sepsis episodes in the patients with catheters locked with the citrate-taurolidine-containing solution (P<0.5). No side effects with the use of citrate-taurolidine catheter lock solution were noted. This study shows that catheter filling with a solution containing the antimicrobial taurolidine may significantly reduce the incidence of catheter-related sepsis. Taurolidine appears to be effective and safe and does not carry the risk for side effects that have been reported for other antimicrobial lock solutions containing gentamicin or high concentrations of citrate.

            Prevention of infectious complications in peritoneal dialysis: best demonstrated practices.

            Peritoneal dialysis (PD) related infections continue to be a serious complication for PD patients. Peritonitis can be associated with pain, hospitalization and catheter loss as well as a risk of death. Peritonitis risk is not evenly spread across the PD population or programs. Very low rates of peritonitis in a program are possible if close attention is paid to the causes of peritonitis and protocols implemented to reduce the risk of infection. Protocols to decrease infection risk in PD patients include proper catheter placement, exit-site care that includes Staphylococcus aureus prophylaxis, careful training of patients with periodic retraining, treatment of contamination, and prevention of procedure-related and fungal peritonitis. Extensive data have been published on the use of antibiotic prophylaxis to prevent exit site infections. There are fewer data on training methods of patients to prevent infection risk. Quality improvement programs with continuous monitoring of infections, both of the catheter exit site and peritonitis, are important to decrease the PD related infections in PD programs. Continuous review of every episode of infection to determine the root cause of the event should be routine in PD programs. Further research is needed examining approaches to decrease infection risk.
