The purpose of this study is to evaluate the usefulness of antifungal lock therapy with liposomal amphotericin B (Ambisome), in combination with systemic antifungal(s), in patients with catheter-related blood stream infections with fungal organisms, whose catheter has not been removed because of the continuing critical need for central line access. The primary group of potential patients will be those with intestinal insufficiency, including post-op small bowel transplant recipients.

The recommendation of the Infectious Disease Society of America (IDSA) is to remove all catheters with fungal infections and treat systemically for 14 days after the last positive culture. However, in certain intestinal failure patients, removal of an infected line might significantly reduce or eliminate intravenous (IV) access and create a life threatening situation. Thus, the investigators' aim is to determine the usefulness of antifungal lock therapy in intestinal failure patients whose catheter has not been removed. The investigators' hope is to salvage central line catheters rather than to remove them.

Further study details as provided by University of Pittsburgh:

Primary Outcome Measures:
  • The success of antifungal lock therapy (the primary endpoint) will be determined by whether or not the patient has at least 2 negative fungal cultures and the CVC was not removed. [ Time Frame: 5 days of antifungal lock treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The number of days before the infected central line culture becomes negative [ Time Frame: 5 days of antifungal lock treatment ] [ Designated as safety issue: No ]
  • The development of fungal-related complications [ Time Frame: Usually 14-28 days ] [ Designated as safety issue: Yes ]
  • Test of cure catheter cultures on day 5 and day 30 post antifungal lock [ Time Frame: 45-55 days ] [ Designated as safety issue: No ]

Enrollment: 13
Study Start Date: September 2006
Study Completion Date: September 2010
Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Antifungal lock-treated patients
Intestinal failure and other patients with poor IV access and central line fungal-related infections
Drug: amphotericin B liposomal (Ambisome)
After enrollment, antifungal therapy will be instituted consisting of both IV systemic and antifungal lock therapy. Systemic therapy will be Ambisome administered IV in a dose of 3-5 mg/kg/day (or other antifungal based upon standard of care) combined with antifungal lock therapy. The antifungal lock therapy consists of placing up to 2.3 ml of concentrated Ambisome (2 mg/ml) into the infected central venous catheter (CVC) and allowing it to dwell uninterruptedly for 8 to 12 hours per day for 10-14 days.

Ages Eligible for Study:   up to 21 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients with intestinal insufficiency and central venous access.
  • Culture positive fungal-related CRBSI.
  • Females of childbearing potential will be eligible for the study.
  • Ambisome carries a category B Pregnancy Risk Factor. Since this is a minimal pregnancy risk category, no special precautions will be taken to determine that the patient is not pregnant.
  • HIV serostatus will not be determined for the purpose of participating in this study.
