Abstract

|
|
Objectives : The purpose of this study was to evaluate the effect of Gwibi-tang (GBT) on renal anemia.
Methods : A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to investigate changes in anemia levels before and after oral administration of GBT in patients with renal anemia. Relevant literature published up to May 25, 2023, was searched in 10 academic electronic databases.
Results : Data from 489 patients from 7 RCTs were obtained and analyzed. All participants were receiving erythropoietin-stimulating agent treatment, and most of them were under hemodialysis. Additional administration of GBT to the participants significantly increased the hemoglobin concentration (10.55 g/L, 95% CI 6.99 to 14.11) compared to the control group. Hematocrit, red blood cell count, serum ferritin concentration, transferrin saturation, and the total effective rate for anemia was also significantly higher in the GBT-treated group than in the control group.
Conclusions : This study suggests that GBT may be considered to be a promising option for the effective management of patients with renal anemia under conventional treatment. However, the limitations of this study, including the quantitative and qualitative weakness of the RCTs, the lack of safety-related evidence, and the absence of long-term follow-up data, should be taken into account when interpreting the results of this study.
