BackgroundCorrection of calcium, phosphorus, and parathyroid hormone disorders is the standard of treatment in nondialysis patients with chronic kidney disease-mineral and bone disorder (CKD-MBD). However, the side effects and adverse reactions are still the main problems. Moreover, the lack of protection of kidney function in the treatment dramatically affects patients' health. Although Traditional Chinese Medicine, specifically tonifying kidney and strengthen bone (TKSB) therapy, is wildly applied to patients with CKD-MBD in China, the evidence of TKSB therapy in the treatment of CKD-MBD is limited. Thus, we conducted this meta-analysis to evaluate the efficacy and safety of TKSB therapy combined with Western medicine (WM) for nondialysis patients with CKD-MBD.MethodsTwo investigators conducted systematic research of randomized controlled trials of TKSB therapy for CKD-MBD from 7 electronic databases. Methodological quality evaluations were performed using the Cochrane collaboration tool, and data analysis was conducted by RevMan v5.3 software and STATA v15.0.ResultsIn total, 8 randomized controlled trials involving 310 patients met the criteria of meta-analysis. The complete results showed that compared with WM alone, TKSB treatment could improve the clinical efficacy rate (risk ratio = 4.49, 95% confidence interval [CI]: [2.64, 7.61], P  .00001), calcium (weighted mean difference [WMD] = 0.11, 95% CI: [0.08, 0.14], P < .00001), serum creatinine (WMD = 45.58, 95% CI: [32.35, 58.8], P < .00001) phosphorus (WMD = 0.11, 95% CI: [0.08, 0.13], P < .00001), parathyroid hormone (WMD = 16.72, 95% CI: [12.89, 20.55], P < .00001), blood urea nitrogen levels (WMD = 0.95, 95% CI: [0.26, 1.64], P = .007) on nondialysis patients with CKD-MBD, which was beneficial to improve the patients' bone metabolic state and renal function. In addition, evidence shows that, compared with WM alone, TKSB treatment is safe and does not increase side effects.ConclusionThe systematic review found that TKSB therapy combined with WM has a positive effect on improving renal function and correcting bone metabolism disorder in nondialysis patients with CKD-MBD, which shows that Traditional Chinese Medicine is effective and safe in treating CKD-MBD. However, more high-quality, large-sample, multicenter clinical trials should be conducted to assess the safety and efficacy of TKSB therapy in treating nondialysis patients with CKD-MBD.Systematic review registration: INPLASY2020120086.Copyright © 2023 the Author(s).
