Background: Liver cirrhosis is one of the end-stage chronic liver diseases. Individuals with chronic hepatitis B (CHB) are at an increased risk of developing liver cirrhosis. Practice guidelines underline that Nucleos(t)ide analogs (NAs) should be the first-line treatment for hepatitis B virus (HBV)-related cirrhosis. However, prolonged use of NAs may lead to drug resistance and kidney impair and does not reverse the fibrosis of liver. Fufang Biejia Ruangan Tablet (RGT), as a traditional Chinese medicine (TCM), has been proved to be effective in the treatment of liver fibrosis. Hence, we will perform meta-analysis in order to evaluate the efficacy and safety of RGT in the treatment of hepatic fibrosis in patients with CHB.
Methods: To search for relative literatures up to February 2019 by computer from the following databases: PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodicals Database, Chinese BioMedical Database and Wanfang Data. Included criteria are randomized controlled trials and cohort studies of hepatic fibrosis in patients with CHB treated by RGT. The primary outcome measures include biochemical and virological parameters. We will use Stata 13.0 software for data synthesis, sensitivity analysis, meta regression, subgroup analysis, and risk of bias assessment. The reporting bias will be assessed by a funnel plot and the funnel plot symmetries will be evaluated by Begg and Egger tests. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the quality of evidence.
Results: This systematic review will provide a synthesis of RGT for hepatic fibrosis in patients with CHB from various evaluation aspects including biochemical and virological parameters, HBV DNA levels HBeAg status and seroconversion, adverse events incidence.
Conclusion: The systematic review will provide evidence to assess the efficacy and safety of RGT in the treatment of hepatic fibrosis in patients with CHB.
