Combined Therapy of Hypertensive Nephropathy with Breviscapine Injection and Antihypertensive Drugs: A Systematic Review and a Meta-Analysis

摘要

Objective. To evaluate the beneficial and adverse effects of breviscapine injection in combination with antihypertensive drugs for treating hypertensive nephropathy in clinical practice. Methods. We searched PubMed, the Cochrane Library, Embase, CNKI, Sino Med, VIP, and Wanfang Data for relevant literature. The timeframe of retrieval was set from the founding date of each database to September 28, 2018. Results. Fourteen papers were included in this study. The quality of all the studies included was determined to be low. All studies were conducted with Chinese populations. Meta-analysis showed that, compared with single-use antihypertensive drugs, using breviscapine injection in combination with antihypertensive drugs to treat hypertensive nephropathy can reduce serum creatinine (Scr) [WMD = -35.16, 95% CI(-50.01, -20.31), P 0.001], blood urea nitrogen (BUN) [WMD = -2.00, 95% CI(-3.07, -0.94), P 0.001], 24-hour urinary total protein (24h UTP) [WMD = -0.04, 95% CI(-0.05, -0.02), P 0.001], and the beta-2-microglobulin (B2M) [WMD = -0.09, 95% CI(-0.11, -0.07), P 0.001], improve creatinine clearance rate (Ccr) [WMD = 7.84, 95% CI(5.20, 10.49), P 0.001], and increase the clinical efficacy [RR = 1.27, 95% CI(1.05, 1.53), P = 0.014], but does not lower systolic blood pressure (SBP) [WMD = -1.02, 95% CI(-2.88, 0.84), P = 0.281]. There was no significant difference in adverse events between experimental groups and control groups. Conclusion. Breviscapine injection in combination with antihypertensive drugs can improve clinical efficacy and Ccr and reduce Scr, BUN, 24h UTP, and B2M in patients with hypertensive nephropathy. The present meta-analysis indicated that breviscapine injection can serve as a renal protective effect to patients with hypertensive nephropathy. However, the evidence of methodological quality and sample sizes is weak, and thus, further standardized research is required.
