ESPEN practical guideline: Clinical nutrition in chronic intestinal failure.

BACKGROUND: This practical guideline is based on the ESPEN Guidelines on Chronic Intestinal Failure in Adults. METHODOLOGY: ESPEN guidelines have been shortened and transformed into flow charts for easier use in clinical practice. The practical guideline is dedicated to all professionals including physicians, dieticians, nutritionists, and nurses working with patients with chronic intestinal failure. RESULTS: This practical guideline consists of 112 recommendations with short commentaries for the management and treatment of benign chronic intestinal failure, including home parenteral nutrition and its complications, intestinal rehabilitation, and intestinal transplantation. CONCLUSION: This practical guideline gives guidance to health care providers involved in the management of patients with chronic intestinal failure.

Results from an Epidemiological Follow-Up Survey on Home Artificial Nutrition in Switzerland from 2010 to 2015.

BACKGROUND: Home artificial nutrition (HAN) is an established treatment for malnourished patients. Since July 2012, the costs for oral nutrition supplements (ONS) are covered by the compulsory health insurance providers in Switzerland if the patient has a medical indication based on the Swiss Society for Clinical Nutrition guidelines. Therefore, the purpose of our study was to analyse the development of HAN, including ONS, before and after July 2012. METHODS: We obtained the retrospective and anonymized data from the Swiss association for joint tasks of health insurers (SVK), who registered patients on HAN. Since not all health insurers are working with SVK, this retrospective study recorded nearly 65% of all new patients on HAN in Switzerland from January 1, 2010, to December 31, 2015. RESULTS: A total of 33,410 patients (49.1% men and 50.9% women) with a mean BMI of 21.3 ± 4.5 kg/m2 and mean age of 68.9 ± 17.8 years were recorded. The number of patient cases on ONS increased from 808 cases in 2010 to 18,538 cases in 2015, while patient cases on home enteral nutrition (HEN) and home parenteral nutrition (HPN) remained approximately the same. The relative distribution of type of HAN changed from 26.2% cases on ONS, 68.7% cases on HEN and 5.1% cases on HPN in 2010 to 86.1% cases on ONS, 12.8% cases on HEN, and 1.1% cases on HPN in 2015. Treatment duration decreased for ONS from 698 ± 637 days to 171 ± 274 days, for HEN from 416 ± 553 days to 262 ± 459 days, and for HPN from 96 ± 206 days to 72 ± 123 days. Mean costs per patient decreased for ONS from 1,330 CHF in 2010 to 606 CHF in 2015. Total costs for HAN increased from 16,895,373 CHF in 2010 to 32,868,361 CHF in 2015. CONCLUSION: Our epidemiological follow-up study showed an immense increase in number of patients on HAN in Switzerland after July 2012. Due to shorter therapy duration and reduced mean costs per patient, total costs were only doubled while the number of patients increased 7-fold.

Evaluation of physical stability of all in one parenteral admixtures for pediatric home care with high electrolytes concentrations / Evaluación de la estabilidad física de preparados parenterales «todo en uno» para atención pediátrica domiciliaria con altas concentraciones de electrolitos

Introduction: The aim of the study was to evaluate stability of 48 total parenteral admixtures for pediatric patients who require home parenteral nutrition. Admixtures contain high amounts of electrolytes. In a clinical practice electrolytes-enrichment of the parenteral nutrition admixtures is a usual demand, especially on the neonatal/pediatric wards. The supplementation of parenteral nutrition with high concentration of electrolytes is a living problem due to decreased stability of lipid emulsions in nutrition admixtures caused by bivalent cations. Methods: Preliminary admixtures were prepared in two-chamber ethylene vinyl acetate bags: amino acids, glucose and electrolytes were combined in one chamber and 20% (w/w) lipid emulsions (SMOFlipid®, Intralipid ® or ClinOleic®) were placed separately in the second chamber. Organic salts of calcium and phosphates were used. Pre-admixtures were stored at +4ºC for up to 21 days after preparation. Each composition of admixtures was prepared twice, because contents of the two chambers were combined at t=0 or after 21 days of storage at +4ºC. Visual observations, globule size distribution (using optical microscopy, laser diffraction and photon correlation spectroscopy methods), pH analyses, zeta potential and surface tension were performed after combining all components together with vitamins. Results: Among 48 of investigated admixtures only two were problematic and other may be stored for at least 21 days at 4°C and completed admixtures demonstrated stability for at least 24 h at room temperature. Conclusion: It was possible to obtain stable admixtures despite of the high concentration of electrolytes (AU)

Introducción: El objetivo del estudio fue evaluar la estabilidad de un total de 48 preparados o mezclas parenterales para pacientes pediátricos con necesidad de nutrición parenteral domiciliaria. Los preparados contienen cantidades elevadas de electrolitos. En la práctica clínica, el enriquecimiento con electrolitos de los preparados de nutrición parenteral es una demanda habitual, especialmente en las unidades neonatales/pediátricas. El complemento de la nutrición parenteral con altas concentraciones de electrolitos es un problema corrriente debido a la menor estabilidad de las emulsiones lipídicas en preparados de nutrición provocada por cationes bivalentes. Métodos: Se prepararon mezclas preliminares en bolsas de etilenvinilacetato de dos cámaras: se combinó amino ácidos, glucosa y electrolitos en una cámara y en la segunda cámara se puso por separado emulsiones lipídicas 20% (w/w) (SMOFlipid®, Intralipid® o ClinOleic®). Se utilizaron sales orgánicas de calcio y fosfatos. Se almacenaron pre-mezclas a +4ºC durante 21 días después de la preparación. Cada composición de mezcla fue preparada dos veces, dado que el contentido de las dos cámaras se combinó en t=0 o después de 21 días después del almacenamiento a +4ºC. Se realizaron observaciones visuales, distribución del tamaño globular (empleando métodos de microscopía óptica, difracción por láser y espectroscopía de correlación fotónica), análisis de pH, potencial zeta y tensión superficial después de combinar todos los componentes a la vez con vitaminas. Resultados: De los 48 preparados investigados solo dos resultaron problemáticos y el resto se pudo almacenar durante al menos 21 días a 4°C y las mezclas completadas presentaron estabilidad durante al menos 24 h a temperatura ambiente. Conclusión: Fue posible obtener preparados estables a pesar de la alta concentración de electrolitos (AU)

Prescription of trace elements in adults on home parenteral nutrition: current practice based on the Canadian Home Parenteral Nutrition Registry.

BACKGROUND: Since the introduction of long-term parenteral nutrition (PN), morbidity due to inadequate replacement or toxicity of routinely administered trace elements has been well described. After decades of experience, much debate still exists about optimal supplementation. In practice, trace elements (TEs) seem to be frequently provided by prescribing an all-inclusive commercial multi-TE admixture with little dosage flexibility. AIM: Our goal was to review TE supplementation practice among 5 PN support centers across Canada, through a retrospective review of the Canadian Home PN Registry. METHODS: Baseline demographic, clinical, and biochemical parameters along with information regarding the PN prescription of 135 patients with complete records were retrieved from the registry database collected between 2005 and 2007. TE supplementation prescriptions were compared with recent guidelines as well as between groups of patients with different PN indications and dietary intake status. Consent was signed by all participating patients. RESULTS: The average daily PN concentrations of TE were as follows: zinc, 8.6 ± 5.5 mg (130.92 ± 84.23 µmol); manganese, 452 ± 184 µg (8.22 ± 3.34 µmol); selenium, 78 ± 45 µg (0.99 ± 0.57 µmol); chromium, 11 ± 5 µg (0.21 ± 0.10 µmol); copper, 0.64 ± 0.35 mg (10.11 ± 5.58 µmol); and iodine, 77 ± 42 µg (0.61 ± 0.33 µmol). The mean daily supplementation of zinc, manganese, copper, and selenium exceeded published recommendations. Patients' underlying anatomy or indication for PN did not significantly influence decisions regarding replacement standards. CONCLUSION: Parenteral TE supplementation in Canadian PN programs needs to be reviewed and adjusted according to most current guidelines. This may require a reevaluation of the commercial TE preparations currently available in Canada and potential new products worldwide to avoid oversupplementation and potential toxicity.

Options available for the infusion of lipid emulsion in home parenteral nutrition (HPN): a questionnaire survey for hospitals in Japan where HPN is practiced.

OBJECTIVE: To understand the status of total parenteral nutritional (TPN) composition and the TPN line used for home parenteral nutrition (HPN) in Japan and to investigate how adequate nutritional support should be in HPN, we conducted a questionnaire survey. METHODS: From February to March 2004, questionnaires were sent by mail to the members of the Japan Society for Home Therapy Research. With the content of the questionnaire, we surveyed 1) the types of medical staff who are involved in HPN, 2) the status of the preparation of TPN fluid and its place of preparation, 3) use of the TPN line and final filter, and 4) administration of lipid emulsion and All-in-One. RESULTS: The major survey results from 66 respondents were that the 50% of the medical staff who are involved in HPN have more than 10 y of experience; however, the number of patients who used HPN and were treated by 78% of the medical staff was fewer than 50. With regard to TPN fluid, 50% was prepared in-house and 12% was prepared by home care service providers. In addition, 58% of institutions were infusing lipid emulsion from the side port of the TPN line or through a peripheral route because they used a final filter and closed system infusion line. CONCLUSIONS: Because the final filter and closed system infusion line for HPN management is standard practice, lipid emulsion is not adequately used in Japan. Therefore, the All-in-One system including lipid emulsion is not used.

4-Hydroxynonenal is markedly higher in patients on a standard long-term home parenteral nutrition.

Parenteral nutrition, a commonly used procedure in patients with gastrointestinal disorders, may lead with time to liver steatosis and fibrosis, whose pathogenesis has yet to be elucidated. Oxidative stress and particularly lipid peroxidation likely contribute to the expression of such hepatobiliary complications, by means of their recognized proinflammatory and profibrogenic effects. To evaluate the adequacy against oxidative insult of a standard micronutrient supplementation in patients under long term parenteral nutrition, a comprehensive patterns of redox indices has been determined on peripheral blood samples from forty one adults in comparison to fifty eight blood donors taken as controls. A sustained oxidative stress in peripheral blood of home parenteral patients was observed. Of the two lipid peroxidation markers found to be markedly increased, namely fluorescent plasma protein adducts with malondialdehyde and 4-hydroxynonenal, respectively, only the second was statistically correlated with all the antioxidant-related changes consistently detected in the patients, namely decreased plasma alpha-tocopherol and selenium intake and higher erythrocyte oxidized glutathione. Plasma level of 4-hydroxynonenal-protein adducts appears to be a reliable and easily measurable marker of oxidative status, particularly indicated to monitor the adequacy of dietary regimen during parenteral nutrition.

[Factors in popularizing home nutritional therapy (HNT) in Japan-analysis of nurse's awareness].

Home nutritional therapy (HNT) is not popular in Japan as compared with American countries. The purpose of this study was to clarify the role of nurses in popularizing HNT. We sent out questionnaires to 469 nurses working at the O University affiliated Hospital, and got 265 responses. As a result, the following two factors were considered to affect the popularization of HNT. 1. Nurses had only a superficial knowledge of the activities of the nutrition support team (NST), and medical care by NST had not been spread. 2. In HNT, there were several gaps between ideals and the real role of nurses.

Micronutrient status in patients receiving home parenteral nutrition.

Administration of home parenteral nutrition (HPN) to patients with intestinal failure requires attention to caloric content of feeds, fluid, electrolyte balance, and micronutrient status. Peripheral blood estimations of vitamins and trace elements may be abnormal, but their clinical significance in relation to deficiency or toxicity states is not always clear. We sought to determine the incidence and nature of clinical micronutrient abnormality in our HPN program. Clinical assessment and case record review of 49 patients actively receiving HPN was undertaken, and, in 32 of these patients, serum micronutrient levels were assayed. Clinical evidence of micronutrient deficiency was identified in 16 patients (33%). Iron deficiency anemia occurred in 14 patients which resolved after iron supplementation in all except 1 patient who had persistent intestinal blood loss. Anemia was precipitated in six patients by identifiable clinical events (acute gastrointestinal disease in five and menorrhagia in one), and in two others folate deficiency coexisted. Biotin deficiency developed in three patients, manifested by dry eyes and angular cheilitis or hair loss. Vitamin A deficiency resulting in visual disturbance developed in one patient who was not receiving multivitamin supplements at that time. Serum levels of zinc, copper, selenium, manganese, vitamin A, and vitamin E were measured in 32 patients. No patient had normal levels of all six micronutrients. Nevertheless, there was no clinical evidence of toxicity or deficiency in any of these patients at the time assays were performed. In conclusion, abnormalities of micronutrient status are common in HPN patients, but serious sequelae appear to be unusual.
