ObjectivesTo systematically review the prognostic value of plasma soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) level in predicting 28-day mortality in sepsis.MethodsPubMed, The Cochrane Library, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect studies about the prognostic value of plasma sTREM-1 in early 28-day mortality in sepsis from inception to April 16th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 14.0 software.ResultsA total of 13 studies involving 1 115 patients were included. The results of meta-analysis showed that the sensitivity and specificity were 79% and 77%, respectively. The positive likelihood ratio and the negative likelihood ratio were 3.4 and 0.28, respectively. The diagnostic ratio was 12. The overall area under the summary receiver operator characteristic (SROC) curve was 0.80.ConclusionsCurrent evidence shows that plasma sTREM-1, as a single index, may play a prognostic role in the early 28-day mortality of sepsis in patients. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
