Effects of adding Rheum officinale to angiotensin-converting enzyme inhibitors or angiotensin receptor blockers on renal function in patients with chronic renal failure: A meta-analysis of randomized controlled trials
.

Abstract

OBJECTIVE:

<italic>Rheum officinale</italic> is a traditional medicinal herb used widely in China to treat chronic renal failure, but the proof of evidence-based medicine is poor. This meta-analysis aims to assess the benefits of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) supplemented with <italic>Rheum officinale</italic> for delaying the progression of chronic renal failure.

MATERIALS AND METHODS:

The MEDLINE, EMBASE, Cochrane Library, SinoMed, Chinese National Knowledge Infrastructure, Wanfang, and VIP databases were searched to identify studies published before September 2016 that investigated the effects of ACEI/ARB plus the Chinese patented medicine Rheum (CPM-Rheum) compared to ACEI/ARB alone in lowering serum creatinine (SCr) and blood urea nitrogen (BUN) levels in chronic renal failure patients. Review Manager 5.3 was used to perform the meta-analysis. Fixed- and random-effects models were used to analyze the data.

RESULTS:

The meta-analysis included nine clinical trials. Comparisons of patients before and after treatment with ACEI/ARB plus CPM-Rheum or ACEI/ARB alone revealed that ACEI/ARB plus CPM-Rheum resulted in significantly greater reductions in SCr (short-term: weighted mean difference (WMD): 17.26, 95% confidence interval (CI): 7.28 - 27.24; long-term: WMD: 63.71, 95% CI: 51.01 - 76.41) and BUN (short-term: WMD: 1.70, 95% CI: 1.27 - 2.12; long-term: WMD: 3.98, 95% CI: 3.14 - 4.82) than ACEI/ARB alone.

CONCLUSION:

In patients with chronic renal failure, the addition of CPM-Rheum to ACEI/ARB significantly lowered both SCr and BUN, particularly after long-term administration. Thus, the combination of ACEI/ARB and CPM-Rheum may improve the treatment of patients with impaired renal function.
