Abstract

BACKGROUND: Soybean oil lipid emulsion may compromise immune function and promote hepatic damage due to its composition of long-chain fatty acids, phytosterols, high proportion of ω-6 fatty acids, and low α-tocopherol levels. Combination lipid emulsions have been developed using medium-chain triglyceride oil, fish oil, and/or olive oil, which provide adequate essential fatty acids, a smaller concentration of ω-6 fatty acids, and lower levels of phytosterols. The purpose of this systematic review is to determine if combination lipid emulsions have a more favorable impact on bilirubin levels, triglyceride levels, and incidence of infection compared with soybean oil lipid emulsions in children receiving parenteral nutrition.

METHODS: This study comprises a systematic review of published studies. Data were sufficient and homogeneous to conduct a meta-analysis for total bilirubin and infection.

RESULTS: Nine studies met the inclusion criteria. Meta-analysis showed that combination lipid emulsion decreased total bilirubin by a mean difference of 2.09 mg/dL (95% confidence interval, -4.42 to 0.24) compared with soybean oil lipid emulsion, although the result was not statistically significant (P = .08). Meta-analysis revealed no statistically significant difference in incidence of infection between the combination lipid emulsion and the soybean oil lipid emulsion groups (P = .846). None of the 4 studies that included triglyceride as an outcome detected a significant difference in…

How strong is the evidence?

Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
