Fermented Cordyceps Powder Combined with ACEI/ARB in Treatment of Diabetic Kidney Disease： A Systematic Review / 中国实验方剂学杂志

ABSTRACT

［Abstract］Objective:To evaluate the efficacy and safety of fermented cordyceps powder combined with angiotensin-converting enzyme inhibitors （ACEI）/angiotensin Ⅱ receptor blocker （ARB） in the treatment of diabetic kidney disease （DKD）. Method:The randomized controlled trials （RCTs） concerning the treatment of DKD with fermented cordyceps powder plus ACEI/ARB were retrieved from Pubmed， Embase， Cochrane library， China National Knowledge Infrastructure （CNKI）， Chinese BioMedical Literature Database on disc （CBMdisc）， Wanfang Data Knowledge Service Platform， and Chongqing Weipu Database for Chinese Technical Periodicals （VIP）. The quality of the included articles was evaluated by the Cochrane Collaboration's tool， followed by data analysis using RevMan 5.3. Result:A total of 48 RCTs were included， involving 4 562 cases. As revealed by Meta-analysis， the effective rate of fermented cordyceps powder combined with ACEI/ARB was higher than that of ACEI/ARB ［risk ratio （RR）=1.20， 95% confidence interval （CI） （1.15，1.24）， <italic>P</italic><0.000 01］. Moreover， such combination effectively reduced urinary albumin excretion rate ［standardized mean difference （SMD）=-2.61，95%CI （-3.17，-2.05），<italic>P</italic><0.000 01］，24-h proteinuria［SMD=-1.75，95%CI （-2.15，-1.35），<italic>P</italic><0.000 01］， serum creatinine（Scr）［mean difference （MD）=-14.57，95%CI （-17.94，-11.21），<italic>P</italic><0.000 01］， blood urea nitrogen（BUN）［MD=-1.05，95%CI （-1.29，-0.81），<italic>P</italic><0.000 01］， cystatin C （Cys-C） ［MD=-0.52，95%CI （-0.68，-0.36），<italic>P</italic><0.000 01］， fasting blood glucose（FBG）［MD=-0.59，95%CI （-0.93，-0.25），<italic>P</italic>=0.000 6］， hemoglobin A1c（HbA1c）［MD=-0.50，95%CI（-0.75，-0.24），<italic>P</italic>=0.000 1］， tumor necrosis factor-<italic>α</italic>（TNF）-<italic>α </italic>［SMD=-1.68，95%CI （-2.21，-1.15），<italic>P</italic><0.000 01］， C-reactive protein（CRP） ［SMD=-1.35，95%CI （-1.77，-0.93），<italic>P</italic><0.000 01］， and interleukin-6 （IL-6） ［SMD=-1.52，95%CI （-1.98，-1.07），<italic>P</italic><0.000 01］. There was no significant difference in the incidence of adverse events between the two groups ［RR=0.77，95%CI （0.49，1.21），<italic>P</italic>=0.25］. Conclusion:Fermented cordyceps powder combined with ACEI/ARB is more effective than ACEI/ARB in the treatment of DKD， which is worthy of clinical promotion and use. More multi-center RCTs with a large sample size are needed for verification.
