ABSTRACT
PURPOSE OF REVIEW: Drug shortages continue to impact our patients with intestinal failure and their ability to receive nutrition. ASPEN guidelines address the management of certain shortages in compounded total parenteral nutrition (TPN); however, some institutions have utilized premixed total parenteral nutrition (pTPN) in place of TPN. RECENT FINDINGS: Premixed TPN appears to be as safe, if not safer, as compounded TPN when comparing the risk of bloodstream infection. However, there is an increased use of supplemental electrolytes to meet patient needs. Cost-effectiveness depends on multiple factors and should be evaluated by each institution when considering the use of TPN. In light of the published information on the use of pTPN compared to TPN, institutions and nutrition clinicians should consider their current practice and opportunities to consider when pTPN may be beneficial for their patients, not only from a safety perspective, but also considering cost savings. However, close monitoring and individual patient needs should be considered as these formulas may not meet all patient nutritional and electrolyte needs.

BACKGROUND: Despite providing significant benefits, home parenteral nutrition (HPN) can be associated with complications such as infections, intestinal failure-associated liver disease, and metabolic abnormalities. Soybean oil (SO)-based intravenous lipid emulsion (ILE) has been noted to contribute to some of these complications, leading to the development of alternative sources of ILE. Mixed-oil (MO) ILE has recently been approved for use in adults with short-term studies revealing a benefit over SO ILE. Currently there is a paucity of data regarding long-term use in the HPN population. METHODS: The current study reports our experience with MO ILE in 9 HPN patients. RESULTS: A total of 9 patients (3 women and 6 men) with average age of 48.1 ± 15.1 years and a median HPN use of 9.9 years (9.0 months-30.7 years) were transitioned from SO ILE to MO ILE as a result of intolerance. The 9 patients tolerated MO ILE well for 140.7 ± 29.7 days. The percentage of calories provided through ILE increased from 7.6 ± 6.5% to 18.4 ± 8.2% (P = .003), whereas the dextrose decreased from 66.9 ± 8.4% to 56.9 ± 5.5% (P = .0007). Although statistical significance was not reached, there was a trend toward improvement in alkaline phosphatase from 138.0 (52-884) to 106 (47-512; P = .09). CONCLUSION: MO ILE was well tolerated in this small cohort and led to improvement in the macronutrient composition of HPN while providing a trend toward improvement in liver studies. These results are promising; however, additional randomized control trials are needed to delineate the true benefit.

BACKGROUND: Catheter-related bloodstream infection (CRBSI) is a common complication in patients receiving home parenteral nutrition (HPN). Data regarding catheter salvage after a CRBSI episode are limited. We aimed to determine the incidence of CRBSI and rates of catheter salvage in adult patients receiving HPN. MATERIALS AND METHODS: We retrospectively searched our prospectively maintained HPN database for the records of all adult patients receiving HPN from January 1, 1990, to December 31, 2013, at our tertiary referral center. Data abstracted from the medical records included demographics, diseases, treatments, and outcomes. The incidence of CRBSI and rates of catheter salvage were determined. RESULTS: Of 1040 patients identified, 620 (59.6%) were men. The median total duration on HPN was 124.5 days (interquartile range, 49.0-345.5 days). Mean (SD) age at HPN initiation was 53.3 (15.3) years. During the study period, 465 CRBSIs developed in 187 patients (18%). The rate of CRBSI was 0.64/1000 catheter days. Overall, 70% of catheters were salvaged (retained despite CRBSI) during the study period: 78% of infections with coagulase-negative staphylococci, 87% with methicillin-sensitive Staphylococcus aureus, and 27% with methicillin-resistant S aureus. The percentage of catheters salvaged was 63% from 1990 to 1994, 63% from 1995 to 1999, 61% from 2000 to 2004, 72% from 2005 to 2009, and 76% from 2010 to 2013. CONCLUSION: Catheter salvage is possible after a CRBSI episode. Since most episodes of CRBSI are caused by skin commensals, effective treatment without removal of the central venous catheter is possible in most cases.
