Abstract

BACKGROUND:

A catheter lock solution containing 1.35% taurolidine and 4% citrate could potentially disrupt bacterial surface adherence and consecutive biofilm production due to the anti-adherence properties of taurolidine and the anticlotting and chelator activities of both compounds.

AIM:

To compare the impact on microbial catheter colonization and infectious complications of heparin and taurolidine citrate as central venous catheter (CVC) lock solutions in paediatric patients with haematological malignancies.

METHODS:

Seventy-one patients aged 1.4-18 years were randomized to two treatment groups using either heparin (N = 36) or taurolidine citrate (N = 35). Infectious complications and clinical side-effects were prospectively monitored and microbial colonization of catheters was assessed at the time of removal.

FINDINGS:

There were two bloodstream infections in the taurolidine citrate group versus nine in the heparin group (0.3 vs 1.3 infections per 1000 catheter-days; P = 0.03). Fever of unknown origin and catheter occlusions were observed with a similar frequency in both groups. Microbial colonization was found in 25.4% catheters. The time of no-lock use, but not the type of lock solution or time of observation, was a significant predictor of catheter colonization (P = 0.004). Colonization was not observed in CVCs used immediately with taurolidine citrate lock. Seven patients in the taurolidine citrate group (20%) experienced side-effects (nausea, vomiting, abnormal taste sensations).

CONCLUSION:

The use of taurolidine citrate lock solution was associated with a significant reduction in bloodstream infection in immunocompromised paediatric patients. Taurolidine citrate may prevent colonization of CVCs if used from the time of insertion, but not after a period of no-lock catheter use.
