Abstract Background Since the introduction of percutaneous endoscopic gastrostomy in the 1980s, the prevalence of home enteral nutrition (HEN) support has increased significantly. Despite these increases, many patients are unable to tolerate standard polymeric formulas (SPFs), resulting in significant healthcare resource utilization. Peptide‐based diets (PBDs) have emerged as a viable option in SPF‐intolerant patients; however, data in the HEN population are lacking. Methods Retrospective review of our prospectively maintained HEN database was conducted to assess tolerance, efficacy, and impact on healthcare utilization in patients on PBDs. Results From January 1, 2016, to May 1, 2018, 95 patients were placed on PBDs, with 53 patients being started directly and 42 patients being transitioned from SPFs. In patients transitioned to PBDs, symptoms of nausea and vomiting, diarrhea, abdominal pain, and distention improved significantly. Healthcare utilization also declined significantly, including mean number of phone calls (1.8 ± 1.6 to 1.1 ± 0.9, P = 0.006), mean number of emergency room visits (0.3 ± 0.6 to 0.09 ± 0.3, P = 0.015), and mean number of provider visits (1.3 ± 1.3 to 0.3 ± 0.5, P < 0.0001). Conclusions Overall, PBDs were well tolerated and resulted in significant improvements in symptoms of gastrointestinal distress and healthcare utilization in patients intolerant to SPFs.

AbstractBackgroundPatients with chronic intestinal failure who require long‐term parenteral nutrition rely on central venous catheters (CVCs) for access to nutrition and hydration. With prolonged use, complications such as central line–associated bloodstream infection (CLABSI), damage to CVC, and central venous thrombosis (CVT) can threaten the availability of life‐preserving access. Because of this, all efforts should be made to preserve CVCs with techniques such as catheter salvage in case of CLABSI and catheter repair when damaged. The present study was conducted to evaluate the effectiveness and safety of catheter repair in our patient population.MethodsRetrospective review in 1253 adult patients who received home parenteral nutrition at the Mayo Clinic between September 1, 1997, and April 30, 2018, was conducted to determine the incidence of CLABSI and CVT in patients who underwent CVC repair.ResultsFifty‐five CVC repairs were performed in 36 patients (n = 23 female) with mean age of 57.05 ± 16.96 years. A total of 14 catheters (25.45%) were complicated with 24 episodes of CLABSI. CLABSI rate before and after repair was 0.23/1000 catheter days and 0.21/1000 catheter days, respectively. Most common indications for eventual catheter replacement were mechanical damage (32%), infection (32%), and switching to alternate mode of nutrition (24%). We had a 100% success rate of catheter repair procedure, and no post‐procedural complications were present.ConclusionCatheter repair can increase the catheter survival without increasing the risk of CLABSI, providing not only socioeconomic benefit but also decreasing risk of compromising future vascular access.

Abstract Background : Although home parenteral nutrition (HPN) is lifesaving for patients with chronic intestinal failure (IF), long‐term use can be associated with complications such as infections, metabolic abnormalities, and IF–associated liver disease (IFALD). The key to treatment of many of these complications is prevention. Guidelines recommend avoidance of overfeeding, use of oral/enteral nutrition if possible, cyclic PN, and maintaining dose of soybean oil (SO) intravenous lipid emulsion (ILE) <1 g/kg/day as preventive strategies for IFALD. Additionally, with development of IFALD, ω‐6/ω‐3 polyunsaturated fatty acid ratio should be decreased in ILE. The newly available mixed‐oil (MO) ILE offers such an opportunity; however, there is a paucity of long‐term data available. Methods : The current study reports our long‐term experience with MO ILE use in HPN patients. Results : Seventeen patients (8 female and 9 male) with an average age of 47 ± 12 years and median HPN duration of 4.6 years (1.1–32.1 years) have utilized MO ILE for >12 months after being transitioned from SO ILE because of intolerance. Use of MO ILE allowed an increase in ILE energy from 8% ± 8% to 22% ± 8% while reducing dextrose energy from 66% ± 8% to 54% ± 5%, maintaining stability in alkaline phosphatase and triglyceride levels, and achieving improvement in aspartate aminotransferase, alanine aminotransferase, total bilirubin, and α‐tocopherol levels. Conclusion : In this HPN cohort with SO ILE intolerance, MO ILE was well tolerated and allowed an improvement in macronutrient composition while improving some liver parameters over a 12‐month period.
