RESUMO
Objective To evaluate the application of neutrophil CD 64 in diagnosis of sepsis in adult patients.Methods Literature retrieval from PubMed, EMBASE, ISI Web of Knowledge, Cochrane Library, CBM, CNKI, CQVIP, Wanfang Data from the establishment of database to the year 2015 was conducted to identify all studies on CD 64 in diagnosis of sepsis .The quality of the literature was evaluated with the quality assessment of diagnostic accuracy studies ( QUADAS).Meta-Disc 1.4 and STATA 12.0 were used for meta analysis . Fixed-effects or random-effects model was performed based on the heterogeneity.The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio were calculated .Summary receiver operating characteristic curves ( SROC ) and area under the curve (AUC) were used to evaluate the diagnostic performance of CD 64 for sepsis.Results A total of 24 studies involving 3 198 patients were included for systemic review .The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of CD 64 for diagnosis of sepsis were 0.79 (95 %CI:0.77-0.81), 0.86 (95 %CI:0.84-0.88), 7.40 (95 %CI:5.02-10.91), 0.15 (95 %CI:0.10-0.22) and 60.07 (95%CI: 29.19-123.60), respectively.The area under SROC of CD64 in diagnosis of sepsis was 0.95, and the Q* value was 0.88.Conclusion CD64 can be used to diagnose sepsis in adult patients , but it needs to be further confirmed by large multicenter studies .
