Ethnopharmacological relevanceXuebijing injection (XBJ), a Chinese patent medicine that was approved for treating sepsis in China in 2004, consists of Carthamus tinctorius L. (Carthami Flos, hong hua), Paeonia lactiflora Pall. (Paeoniae Radix Rubra, chi shao), Ligusticum chuanxiong Hort. (Chuanxiong Rhizoma, chuan xiong), Salvia miltiorrhiza Bge. (Salviae Miltiorrhizae Radix Et Rhizoma, dan shen) and Angelica sinensis (Oliv.) Diels (Angelicae Sinensis Radix, dang gui).Aim of the studyThis study aimed to assess the efficacy and safety of XBJ combined with routine treatment (RT) for treating sepsis through systematic review and meta-analysis.Materials and methodsDatabases including Embase, PubMed, the Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Journal Database (VIP) and the Wanfang database were searched from inception to June 6, 2017 to collect relevant RCTs comparing XBJ combined with RT and RT alone for sepsis. The primary clinical outcomes were 28-day mortality and mortality during treatment. The secondary outcomes of our study included APACHE Ⅱ scores, WBC counts, body temperature, and adverse events or reactions. We excluded low-quality studies (Jadad score < 3) and calculated risk ratios (RR) for primary outcomes with fixed effects models. We assessed quality of evidence using the grading of recommendations assessment, development, and evaluation (GRADE) approach.ResultsWe identified 1602 records, and 16 RCTs (1144 patients) were included. Moderate-quality evidence suggested that combined therapy reduced 28-day mortality (934/1144, RR 0.62, 95% CI 0.51–0.76 P < 0.000 01, I² = 0%), APACHE Ⅱ scores (792/1144, MD −3.53, 95% CI −4.49 to −2.54; P < 0.000 01, I² = 59%) and body temperature (362/1144, MD −0.43, 95% CI −0.55 to −0.31; P < 0.000 01, I² = 0%). Very low-quality evidence showed that WBC count improved with combined medication at high dosages (one study included, 40/1144, MD −8.00, 95% CI −10.18 to −5.82), but there was no reduction at moderate dosages (230/1144, MD −2.38, 95% CI −5.01 to 0.25; P = 0.08, I² = 70%). However, moderate-quality evidence indicated positive results with low dosages (142/1144, MD −2.88, 95% CI −3.79 to −1.96; P < 0.000 01, I² = 0%). Nevertheless, due to the insufficient number of studies and the poor quality of the current evidence, more studies of dose-effect relationships and safety concerns of XBJ are needed. Low-quality evidence showed no risk difference for mortality during treatment (210/1144, RR 0.65, 95% CI 0.36–1.17; P = 0.15, I² = 0%).ConclusionsThis study suggested that supplementation with XBJ in addition to regular treatment may improve the 28-day mortality rate, APACHE Ⅱ scores, WBC count and body temperature of sepsis patients without serious adverse events, but it may not reduce mortality during treatment, revealing a specific, remote effect of traditional Chinese medicine. However, given the high risk of bias and the low quality of the included trials, we may be unable to draw any conclusions about its routine use. Rigorously designed, multicentre, large-scale, methodologically sound trials are warranted.
