Objective To systematically review the efficacy of antibiotic treatment in sepsis patients under the guidance of procalcitonin. Methods Databases including PubMed, The Cochrane Library (Issue 9, 2016), EMbase, Web of Science, CBM, WanFang Data, VIP and CNKI were electronically searched from inception to September 2016 to collect randomized controlled trials (RCTs) about antibiotic treatment in sepsis under the guidance of procalcitonin. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies, and then meta-analysis was performed by RevMan 5.3 software. Results A total of 15 RCTs involving 3 328 sepsis patients were included. Among them, 1 649 were in the procalcitionin group and 1 679 patients in the control group. The results of meta-analysis showed that:the PCT group could significantly reduce the using time of antibiotics (MD=-2.37, 95%CI -2.96 to -1.78, P<0.000 01), the ICU length of stay (MD=-0.26, 95%CI -0.46 to -0.07, P=0.007), the hospital length of stay (MD=-2.78, 95%CI -4.53 to -1.04, P=0.002), as well as the 28-day mortality (MD=0.78, 95%CI 0.66 to 0.93, P=0.005). There were no significant differences between the two groups in ICU mortality, in-hospital mortality and clinical cure rate. Conclusion Using the procalcitontin to guide the antibiotic treatment in sepsis can reduce the patients' use of antibiotics, ICU length of stay, in-hospital length of stay and 28-day mortality, but can not reduce the patients' ICU mortality, in-hospital mortality and clinical cure rate. Due to the limited quality and quantity of included studies, the current conclusions are needed more studies to validate.
