Long-term venous devices (e.g.Ports, tunneled catheters,...) may become infected. Sometimes it is very difficult to treat the infection and it is necessary to remove the device. The purpose of this study is to determine the efficacy of instilled ethanol ("ethanol lock therapy") versus instilled antibiotics ("antibiotic lock therapy") to save long-term venous device when infected, preventing their removal.

Condition Intervention Phase
Drug: Ethanol-lock therapy

Further study details as provided by IRCCS Policlinico S. Matteo:

Primary Outcome Measures:
  • Ratio of saved devices [ Time Frame: 7 days ]

Secondary Outcome Measures:
  • Number of participants with adverse events linked to ethanol lock as a measure of safety and tolerability [ Time Frame: 60 days ]

    Major adverse event (stop protocol): anaphylaxis, antabuse-like reaction, device damage, severe dysphoric reaction.

    Minor adverse events (do not stop protocol): nausea, vomiting, headache, dizziness.

  • Number of patients with proper parenteral therapy [ Time Frame: 7 days ]
    Verified by an Infectious Diseases Specialist

  • Ratio of saved devices [ Time Frame: 15-30-60 days ]
  • Time for next bacteriemic episode [ Time Frame: 30 days after the end of lock ]

Estimated Enrollment: 200
Study Start Date: June 2010
Estimated Study Completion Date: June 2013
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ethanol-lock
Treatment with a combination of ethanol-lock and parenteral therapy
Drug: Ethanol-lock therapy
Daily ethanol-lock with 70% ethanol instilled in device dead-space, leaved in place for the longest possible interval, and then discarded. For dialysis devices, it is acceptable to leave the lock in place between dialysis sessions. Lock therapy will be continued for 7 days.
Active Comparator: Antibiotic lock
Treatment with a combination of antibiotic-lock and parenteral therapy
Drug: Antibiotic-lock
Daily antibiotic-lock according to 2009 IDSA Guidelines,instilled in device dead-space, leaved in place for the longest possible interval, and then discarded. For dialysis devices, it is acceptable to leave the lock in place between dialysis sessions. Lock therapy will be continued for 7 days.
