 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.
