Abstract
Clinical trials have reported that a four-oil intravenous lipid emulsion (SMOFlipid) play a positive role in immune function, but showed inconsistent outcomes compared to other lipid emulsions. A systematic review and meta-analysis was conducted to evaluate the effect of SMOFlipid on liver function, triglycerides (TG), inflammatory markers, and clinical outcomes in hospitalized adults after short-term use compared to others. A search of the PubMed, Medline, Embase, China National Knowledge Infrastructure, and Wanfang databases was performed to identify the included randomized controlled trials. Trials with adults who were administrated a short-term course of SMOFlipid were included. A meta-analysis on liver function markers, TG, inflammatory markers, and clinical outcomes was conducted. A total of 18 randomized controlled trials with 1188 patients were included. Compared to other lipid emulsions, SMOFlipid was associated with a significant reduction in ALT, AST, γ-glutamyltransferase, total bilirubin, TG, C-reactive protein and length of hospital stay. No effect on serum interleukin-6 levels or adverse events were observed. For adult patients, our meta-analysis indicated that SMOFlipid may be beneficial to the liver and prone to prevent hyperlipidemia. The SMOFlipid also shortened length of hospital stay.

Abstract
Fat is an important macronutrient in the human diet. For patients with intestinal failure who are unable to absorb nutrients via the enteral route, intravenous lipid emulsions play a critical role in providing an energy-dense source of calories and supplying the essential fatty acids that cannot be endogenously synthesized. Over the last 50 y, lipid emulsions have been an important component of parenteral nutrition (PN), and over the last 10-15 y many new lipid emulsions have been manufactured with the goal of improving safety and efficacy profiles and achieving physiologically optimal formulations. The purpose of this review is to provide a background on the components of lipid emulsions, their role in PN, and to discuss the lipid emulsions available for intravenous use. Finally, the role of parenteral fat emulsions in the pathogenesis and management of PN-associated liver disease in PN-dependent pediatric patients is reviewed.

Effects of glucose or fat calories in total parenteral nutrition on fat metabolism and systemic inflammation in rats. Metabolism 2011; 60:195-205. [PMID: 20096898 DOI: 10.1016/j.metabol.2009.12.014] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2009] [Revised: 12/08/2009] [Accepted: 12/14/2009] [Indexed: 10/19/2022]
Abstract
This study compared the effects of total parenteral nutrition (TPN) by central vein with or without fat provided at maintenance energy requirement on fatty acid metabolism, de novo lipogenesis, and the risk of hepatic and systemic inflammation in rats. Study 1 was conducted in 2 groups: high glucose (HG), where fat-free TPN was given at maintenance levels of 180 kcal/(kg d), and low glucose (LG), where fat-free TPN containing 30% fewer calories at 126 kcal/(kg d) was provided by reducing 54 kcal/(kg d) from parenteral glucose. Study 2 contained 3 TPN groups: 1 LG group at 126 kcal/(kg d) and 2 groups at 180 kcal/(kg d) with 30% of total calories (54 kcal/[kg d]) either from soybean or fish oil emulsion. In both studies, animals fed a chow diet ad libitum were included. Plasma and hepatic triglyceride and phospholipid fatty acid profiles, enzymes indicating hepatic injury, and C-reactive protein levels (CRP) reflecting systemic injury were measured. In study 1, evidence of de novo lipogenesis was noted in LG and was more prominent in HG with elevation of CRP in HG. In study 2, de novo lipogenesis was reduced by adding either fat to LG to achieve maintenance energy levels. Moreover, adding fat as soybean oil but not fish oil significantly increased plasma and hepatic triglyceride and also elevated aspartate aminotransferase and CRP levels, reflecting inflammation. Thus, in rats, either hypocaloric feeding as glucose-based TPN or TPN provided at maintenance energy levels with the addition of fish oil limits hepatic lipid accumulation and prevents the evidence of hepatic and systemic injury found with maintenance level TPN as glucose only or glucose plus soybean oil.
