Abstract:

Objective

To systematically evaluate the clinical efficacy of continuous renal replacement therapy (CRRT) combined with ulinastatin in patients with severe sepsis.

Methods

The randomized controlled trials (RCTs) on patients with severe sepsis treated by CRRT combined with ulinastatin were searched from PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang and VIP databases published up to January 2020. Two reviewers independently screened articles and extracted data according to inclusion and exclusion criteria, and evaluated the quality of included studies. Then meta-analysis was conducted using Review Manager 5.3 software.

Results

A total of 24 RCTs involving 1 636 patients were included in this study, with 823 patients in the experimental group (CRRT combined with ulinastatin) and 813 patients in the control group (CRRT alone). Meta-analysis showed that as compared with the control group, the mortality [relative risk= 0.39, 95% confidence interval (CI) (0.31, 0.50), Z= 7.65, P< 0.000 01] and acute physiology and chronic health evaluation Ⅱ [mean differences (MD)=-3.53, 95%CI (-3.96, -3.10), Z = 16.04, P<0.000 01] were lower, the mechanical ventilation time [MD= -2.76, 95%CI (-4.57, -0.96), Z = 3.00, P = 0.003] was shorter, the levels of tumor necrosis factor-alpha [standardized mean difference (SMD) = -1.75, 95%CI (-2.75, -0.76), Z = 3.44, P = 0.000 6], interleukin-6 [SMD = -2.29, 95%CI (-2.90, -1.67), Z = 7.32, P<0.000 01], interleukin-8 [SMD = -1.77, 95%CI (-2.43, -1.10), Z = 5.21, P<0.000 01], procalcitonin [MD=-2.63, 95%CI (-3.66, -1.60), Z = 5.01, P<0.000 01], C-reactive protein [MD = -15.80, 95%CI(-19.45, -12.15), Z = 8.48, P<0.000 01], D-dimer [MD = -1.48, 95%CI (-1.54, -1.41), Z = 44.38, P<0.000 01], prothrombin time [MD = -3.49, 95%CI (-5.32, -1.65), Z = 3.72, P = 0.000 2] and activated partial thomboplastin time [MD = -5.28, 95%CI (-7.79, -2.76), Z = 4.11, P<0.000 1] were decreased in the experimental group. However, the duration of antibiotic use [MD = -0.19, 95%CI (-0.79, 0.42), Z = 0.61, P = 0.54] and platelet count [MD = 34.71, 95%CI (-15.51, 84.93), Z = 1.35, P = 0.18] were not significantly different between the two groups.

Conclusion

CRRT combined with ulinastatin is more effective in treating patients with severe sepsis than CRRT alone.
