The Use of Antifungal Lock Therapy in Intestinal Failure and Other Patients
In Brief
A Phase 4 clinical trial evaluating amphotericin B liposomal (Ambisome) for Central Line Fungal Infections. Completed, enrolled 13 participants across 1 site.
Detailed Summary
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.

Interventions
After enrollment, antifungal therapy will be instituted consisting of both systemic and antifungal lock therapy. Systemic therapy will be amphotericin B liposomal (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 sufficient amphotericin B liposomal (Ambisome \[2 mg/ml\]) lock solution into the infected central venous catheter (CVC) and allowing it to dwell uninterruptedly for 8 to 12 hours per day for 10-14 days (largest CVC = 2.3 mL).
