Compound glycyrrhizin injection may have adjuvant therapeutic effects in improving liver function for children with acute icteric hepatitis, showing superiority in reducing bilirubin, alanine aminotransferase, and aspartate transaminase levels when combined with conventional western medicine treatment. However, the evidence regarding its safety and overall therapeutic effects is currently limited and further well-designed randomized controlled trials are needed for verification.
Background: Compound glycyrrhizin injection (CGI) is a preparation with glycyrrhizin as the main active ingredient extracted from licorice. As clinical trials suggest that CGI is effective in improving liver function for acute icteric hepatitis in children (AIHC), this systematic review aimed to evaluate and verify its therapeutic effects and safety. Methods: Six electronic databases were searched from their inception to 15 May 2021. Randomized controlled trials (RCTs) assessing therapeutic effects and safety of CGI for AIHC were included. The risk of bias for each trial was assessed using the Cochrane Risk of Bias Tool 2.0. Primary outcomes were indexes related to liver function, including total bilirubin (TBiL), alanine aminotransferase (ALT) and aspartate transaminase (AST). RevMan 5.4 software was used for data analyses. The certainty of the evidence was assessed using the online GRADEpro tool. Results: Six RCTs involving 608 children were included. The overall bias was assessed as having high risk of bias in all trials. All trials compared the combination of CGI and conventional western medicine (CWM) with CWM alone. Regarding the effects of CGI for AIHC, results showed that CGI plus CWM was superior to CWM alone in reducing the levels of TBiL (mean difference (MD) = -8.19 mmol/L, 95% CI-9.86 to -6.53), ALT (MD = -24.09 U/L, 95% CI-30.83 to -17.34) and AST (MD = -18.67 U/L, 95% CI-21.88 to -15.45). No trial reported adverse events. The certainty of the evidence for outcomes were all evaluated as low or very low. Conclusion: CGI may have adjuvant therapeutic effects on improving the liver function of children with AIHC. There is no evidence to determine the safety of CGI for AIHC. As current evidence is weak, further well-designed RCTs are required for verification of the therapeutic effects of CGI. (C) 2021 Korea Institute of Oriental Medicine. Published by Elsevier B.V.
