ObjectiveTo evaluate the clinical efficacy of fish oil containing lipid emulsion (FO) in sepsis.
MethodsRandomized controlled trials about fish oil containing lipid emulsion in sepsis,which were published from 1980,were searched from the following electronic databases:PubMed,Embase,Foreign Medical Journal Service,Cochrane Library,CNKI,Wanfang Database,and VIP Database. The articles screening,quality assessment and data extraction were conducted by two reviewers independently. The methodological quality of trials was assessed by Jadad's scale. All data was analyzed by Review Manager 5.2 software.
ResultsFifteen studies involving 794 participants met the inclusion criteria. The meta-analysis results were as follows:compared with the control group,①FO could shorten the length of ICU stay[WMD=-5.59,95%CI(-7.65,-3.53)] and the length of hospital stay[WMD=-10.48,95%CI(-14.67,-6.29)],and also decrease the 28-day mortality[RR=0.69,95%CI(0.52,0.93)]. ②FO could reduce the concentration of TNF-α[WMD=31.78,95%CI(5.63,57.92)] and improve oxygenation index[WMD=41.95,95%CI(30.80,53.11)] in septic patients. ③There was no statistical significance in the decrease of C-reactive protein (CRP) between two groups(P>0.05).
ConclusionThe administration of FO in septic patients can significantly shorten the length of ICU stay and hospital stay,decrease the 28-day mortality,reduce the concentration of TNF-α and improve oxygenation index. However,it shows no significant difference in the decrease of CRP compared with the administration of traditional lipid emulsion. All of the above results show that the septic patients can benefit from the administration of fish oil containing lipid emulsion.
Objective To investigate the immunoregulatory effects of immunonutrient ω-3 polyunsaturated fatty acid (PUFA) and its applications in organ transplantation. Methods Relevant literatures of recent years were reviewed. Results The immunoregulatory effects of ω-3 PUFA can inhibit proliferation and activation of the immunocompetent cells including T cell and B cell, reduce cytokine production, modulate immunologic response, improve graft function, pro-long survival, reduce episodes of rejection, and lessen adverse reactions of immunosuppressor.Conclusion ω-3 PUFA should have wide applications in organ transplantation due to its immunoregulatory effects. However, this research should be further studied.
