OBJECTIVE: The presence of phytosterols in vegetal lipid emulsions has been  associated with alterations of liver function tests. Determination of phytosterols  content, currently undeclared, would allow the development of strategies to  prevent or treat these alterations. METHOD: 3-4 non-consecutive batches of 6 lipid emulsions from different providers (Clinoleic, Intralipid, Lipofundina, Lipoplus, Omegaven and Smoflipid) were analyzed. Differences in total phytosterol assay between providers and batches were statistically studied by a one-way ANOVA and Kruskal-Wallis non-parametric approximation and post hoc Scheffé test (p < 0...

BACKGROUND: Infants born prematurely are at risk of a deficiency in ω-6 and ω-3 long-chain polyunsaturated fatty acids (LC-PUFAs) arachidonic acid (AA) and docosahexaenoic acid (DHA). We investigated how fatty acids from breast milk and parenteral lipid emulsions shape serum LC-PUFA profiles in extremely preterm infants during early perinatal life. METHODS: Ninety infants born < 28 weeks gestational age were randomized to receive parenteral lipids with or without the ω-3 LC-PUFAs eicosapentaenoic acid (EPA) and DHA (SMOFlipid: Fresenius Kabi, Uppsala, Sweden, or Clinoleic: Baxter Medical AB, Kista, Sweden, respectively)...

INTRODUCTION: Newborn infants and small children require large amounts of calcium and phosphate in a low volume of solution which can increase the risk of precipitation of calcium phosphate. Calcium gluconate is the predominant calcium salt form employed in parenteral nutrition (PN) compounding due to its solubility profile with phosphate. Unfortunately, calcium gluconate contains higher levels of aluminum contamination than calcium chloride, resulting in an increased potential for aluminum toxicity in patients receiving traditional PN...

BACKGROUND: Parenteral nutrition (PN) is associated with bronchopulmonary dysplasia in premature infants. In animals, PN leads to alveolar loss following stimulation of apoptosis by oxidative stress (oxidized redox potential). Peroxides and aldehydes generated in PN can induce hypo-alveolarization. The implication of peroxides, which is reduced by light protection, is demonstrated. The implication of aldehydes from omega-6 fatty acids oxidation is expected. The hypothesis is that composition and light exposure of PN influences bronchopulmonary dysplasia development...

At an intensive care unit, four neonates died consecutively within 80 minutes. Citrobacter freundii was isolated from blood samples of the 4 patients. It was also cultured from the leftover SMOFlipid that had been infused intravenously into the patients. In this in vitro study, we evaluated the bacterial growth kinetics and change in size of fat globules in SMOFlipid contaminated with C. freundii. Following the growth of bacteria, pH of SMOFlipid decreased to < 6, and the number of fat globules larger than 5 μm increased...

Lipid emulsions have been associated with liver injury. Newer mixed emulsions (ML), such as SMOFlipid (Fresenius Kabi, Germany), are thought to be more hepatoprotective than soybean-based emulsions (SL), such as Intralipid (Baxter). Pediatric studies comparing long-term use between the 2 are limited. This study compares the severity of hepatic injury between a prospective cohort of hospitalized children on ML (n = 20) and a historical age- and diagnosis-matched cohort of hospitalized children on SL (n = 20)...

Neonatal units have started to switch from using conventional soy-based to alternate lipid emulsions, like SMOFlipid. SMOFlipid has been associated with an improvement in biochemical parameters and delays progression of parenteral nutrition-associated liver disease (PNALD). This retrospective epoch study aimed to compare clinically relevant neonatal outcomes in preterm infants (< 32 weeks), receiving SMOFlipid versus Intralipid. We compared clinical outcomes in two epochs-epoch 1 (Intralipid, October 2013-June 2015) versus epoch 2 (SMOFlipid, July 2015-March 2017)...

There is increasing interest to administer ibuprofen as a continuous infusion instead of a traditional bolus for treating Patent Ductus Arteriosus (PDA). However, its compatibility data with commonly used drugs in the neonatal period, including parenteral nutrition (PN) and lipids is unavailable. The aim is to determine the compatibility of intravenous ibuprofen lysine with various ANZNN parenteral nutrition consensus group standard neonatal PN formulations and lipids. The PN and lipid solutions used in a tertiary neonatal unit were obtained...

Long-term parenteral nutrition (PN) may be complicated by PN-associated liver disease (PNALD), and some studies suggest an association between the use of soy-based fat emulsions and PNALD development. Patients' liver function typically improves and PNALD resolves after reducing or stopping a soy-based fat emulsion, and thus lipid minimization has been the primary strategy for managing PNALD in many intestinal rehabilitation programs. However, fat emulsions often cannot be stopped entirely, leading some patients to develop PNALD even after lipid reduction strategies have been implemented...

Since early work by Wretlind and Schuberth led to the development of a stable and safe intravenous fat emulsion (IFE) using soybean oil (SO) and egg phospholipid emulsifier, IFEs have become a crucial source of essential fatty acids and nonprotein energy in parenteral nutrition. However, largely due to their high ω-6 polyunsaturated fatty acid (PUFA) and phytosterol content, SO IFEs have been associated with complications, including a proinflammatory profile and hypertriglyceridemia, as well as intestinal failure-associated liver disease...

Studies discussing inflammation and oxidative stress state that these conditions are known contributors in the pathogenesis of cholestatic diseases and ulcerative colitis, and studies examining patients with liver disease have found decreased antioxidant status and significant elevation of lipid peroxides as compared with healthy subjects. One hypothesis in liver disease is that deficient antioxidant defense mechanisms may lead to excess oxygen free radical formation, which promotes deleterious processes in the liver...

BACKGROUND/OBJECTIVES: Parenteral nutrition (PN) incorporating omega-3 fatty-acid-enriched lipid emulsions has been shown to be cost effective in Western populations. A pharmacoeconomic evaluation was performed within the Chinese intensive care unit (ICU) setting. This assessed whether the additional acquisition cost of PN with omega-3 fatty-acid-enriched lipid emulsion (SMOFlipid) vs standard PN was offset by improved clinical outcomes that can reduce subsequent costs. MATERIALS AND METHODS: A pharmacoeconomic discrete event simulation model was developed, based on an update to efficacy data from a previous international meta-analysis, with China-specific clinical and economic input parameters...

Plasticizers migrate from polyvinylchloride (PVC) infusion systems into lipid emulsions. The aim of this study was to investigate the leaching of different plasticizers from PVC perfusion lines by a selection of lipid emulsions under clinical conditions. Seven PVC perfusion lines with an equal length of 150cm and three internal diameters were perfused with three lipid emulsions: Intralipid(®) 20%, ClinOleic(®) 20% and SMOFlipid(®) 20%, mimicking clinical conditions. The concentrations of the plasticizers were measured directly in the emulsions by gas chromatography - mass spectrometry...

Lipid emulsions for parenteral nutrition are used to provide calories and essential fatty acids for patients. They have been associated with hypertriglyceridemia, hypercholesterolemia, and metabolic stress, which may promote the development of endothelial dysfunction in patients. The aim of the present study was to determine whether five different industrial lipid emulsions may affect the endothelial function of coronary arteries. Porcine coronary artery rings were incubated with lipid emulsions 0.5, 1, or 2% (v/v) for 30 min before the determination of vascular reactivity in organ chambers and the level of oxidative stress using electron paramagnetic resonance...

BACKGROUND: Preterm neonates and those with intestinal failure require prolonged parenteral nutrition (PN) during a critical time of early central nervous system maturation. Conventional lipid emulsions fed to preterm neonates lack n-3 (ω-3) long-chain polyunsaturated fatty acids (LC-PUFAs; >20 carbon chain in length). Recently, fish oil lipid emulsions have been developed that provide both n-6 (ω-6) and n-3 LC-PUFAs, precursors of very long-chain PUFAs (VLC-PUFAs; >24 carbon chain in length)...
