Objective To assess the efficacy of Tongxinluo for diabetic kidney disease. Methods we conducted a systematic review of randomized controlled trials (RCTs) in which Tongxinluo was used to treat diabetic kidney disease. And we screened relevant studies according to predefined inclusion and exclusion criteria, evaluated the quality of the included studies, and performed meta-analyses by using The Cochrane Collaboration’s Revman 5.0 software. Results A total of 11 RCTs were enrolled in the review. The results of meta-analysis showed that Tongxinluo was better on attenuating 24 hour urinary protein,BUN and UAER; Tongxinluo was not superior to no treatment on the improvement of Scr and Ccr; Tongxinluo was better than no treatment on the Regulation of blood lipids, such as TC, TG, LDL-C. However, Tongxinluo might have similar effects on the improvement of HDL-C; Tongxinluo was better than no treatment on the improvement of FBG, but xuezhikang was not superior to no treatment on the improvement of P2BG and HbA1c. Tongxinluo was better than no treatment in decreasing plasma endothelin (ET). No significant adverse effects or Allergic reactions were reported. Conclusion The evidence currently available shows that Tongxinluo has some effect and is relatively safe in treating patients with diabetic kidney disease.Due to a high risk of selection bias and detection bias in the included studies, the evidence is insufficient to determine the effect of Tongxinluo. Further large-scale trials are required to define the role of xuezhikang in the treatment of DKD.
Objective To assess the effectiveness of statins in treating early diabetic kidney disease (DKD). Methods We searched the Cochrane Central Register of Controlled Trials (Issue 2, 2009), MEDLINE (1991 to August 2009), EMbase (1991 to August 2009), CBMdisc (1991 to August 2009) and CNKI (1994 to August 2009). We also handsearched relevant journals and conference proceedings. Randomized controlled trials (RCTs) in which statins were used to treat patients with early DKD were collected. Then we screened the retrieved studies according to predefined inclusion and exclusion criteria, evaluated the quality of the included studies, and performed meta-analyses by RevMan 4.2 software. Results A total of 281 articles were found and 22 articles inolving 1838 patients were finally included. All these articles were regarded as low quality. We chose the random-effect model to conduct meta-analysis because significant heterogeneities were found among these articles. The results of meta-analysis showed that after treatment with statins, there were significant reductions in urinary albumin excretion rate (UAER) (WMD= –55.77, 95%CI –74.20 to –37.34, Plt;0.000 01), serum creatinine (Scr) (WMD= –4.34, 95%CI –6.74 to –1.94, P=0.000 4), C reactive protein (CRP) (WMD= –1.48, 95%CI – 2.32 to – 0.63, P=0.006), total cholesterol (TC) (WMD= –1.33, 95%CI –1.75 to –0.91, Plt;0.000 01), and triglyceride (TG) (WMD= –0.72, 95%CI-1.17 to -0.27, P=0.002) in group treatment compared with group control. Funnel-plot displayed a symmetrical figure, indicating there was no publication bias. No severe adverse effects were found in these articles except 12 patients with high level of transaminase which were cured after using hepatic protect therapy. Conclusion Currently available evidence shows that with the reduction of TC and TG, statins may decrease UAER and Scr in patients with early DKD and the reduction of CRP may be involved in the mechanism. Statins provide effective renal protection and no severe adverse effects in treating early DKD. However, due to lack of quality in the included studies, more studies of better quality should be conducted
Objective To study the association between the insertion(I)/deletion(D) polymorphism of the angiotensin-converting enzyme gene intron 16 (ACE/ID) and diabetic nephropathy (DN) among Chinese population by Meta-analysis. Methods Odds ratios of ACE/ID genotype distributions were analyzed in NIDDM or IDDM patients with and without DN. All the related studies on ACE/ID polymorphism and DN were identified while poor-qualified studies were excluded, and the risk of publication bias was estiMetad. The Meta-analysis software, RevMan 3.1, was applied for investigating heterogeneity among individual studies and summarizing effects across studies by proper statistical methods. Result The pooled odds ratios (with 95%CI) of DD vs ID + II and II vs ID + DD were 2.17 (1.74-2.70) and 0.49 (0.36-0.66) in NIDDM (12 studies), 3.92 (2.05-7.47) and 0.19 (0.09-0.43) in IDDM (3 studies) respectively (Plt;0.01). Conclusion In both NIDDM and IDDM, ACE/ID polymorphism is believed to be associated with diabetic nephropathy. The number of DN patients with DD genotype has been increased while that with II genotype decreased.
Objective To evaluate the effectiveness and safety of spironolactone for diabetic nephropathy. Methods We electronically searched CENTRAL (issue 3, 2008), MEDLINE (1950 to August 2008), EMbase (1984 to August 2008), CNKI (1994 to September 2008), and VIP (1989 to August 2008). We also checked the reference lists of all papers identified for further trials. Randomized controlled trials (RCTs) and quasi-RCTs were identified and analyzed according to the Cochrane Handbook for Systematic Reviews of Interventions. Results Three RCTs were included. Meta-analysis was not performed due to heterogeneity. Trials showed that spironolactone might decrease urinary albumin excretion, but could scarcely play an important role on kidney function and blood pressure. Conclusion Affirmative assessment cannot be made about the effectiveness and safety of spironolactone for diabetic nephropathy according to the limited existing trials. Large-scale, high-quality RCTs are needed to confirm or refuse the available evidence.

Objective To perform a meta-analysis and investigate the correlation between angiotensin-I converting enzyme gene insertion (I), deletion (D) polymorphism and type 2 diabetic nephropathy, assessing the bias of small sample size study and heterogeneity between studies. Methods MEDLINE, EBSCO, EMbase, PubMed, CHKD, CNKI, CBM, VIP and WanFang Data were searched (from January 1994 to March 18th 2011) for relevant case-control studies. Two reviewers independently identified the literature according to inclusion and exclusion criteria. Also references of the included literature were retrieved. Then data were extracted and assessed by the Newcastle-Ottawa Scale (NOS). Meta-analysis was performed using RevMan 5.0.0 software. Results A total of 61 studies comprising 9 979 cases and 7 252 control subjects were included. There was b evidence of heterogeneity (Plt;0.05, I2=60%) and a random effect model was employed to summarize the data. Results of meta-analysis showed that T2DM patients with II genotype had lower incidences of DN than those with DD+DI genotype (OR=0.65, 95%CI 0.57 to 0.74). The results of subgroup meta-analysis showed that Chinese, Japanese and Brazilians patients with II genotype had lower incidences of DN. However, there were no relation among Caucasus, Middle-East, Indian, Mexican, Korean, and Malaysian patients. Conclusion As for T2DM patients, their angiotensin-I converting enzyme gene insertion (I), deletion (D) polymorphism relates to DN. T2DM patients with II genotype have lower incidences of DN. But the difference of this relation varies with ethnicity.
Objective To evaluate the efficacy and safety of tripterygium for diabetic nephropathy. Methods All randomized or quasi-randomized controlled trials (RCTs or quasi-RCTs) of tripterygium for biabetic nephropathy were collected from The Cochrane Library (Issue 1, 2010), MEDLINE (1996 to March 2010), CNKI (1994 to March 2010), and CBM (1978 to March 2010). Two reviewers evaluated the quality of the trials and extracted the data independently. RevMan 5.0 software was used for meta-analyses. Results A total of 12 RCTs involving 862 patients were identified. The methodology of the included trials was poor and potential publication bias existed. The meta-analyses results showed: (1) Compared with the conventional treatment, the tripterygium showed more effects in reducing the 24-hour urinary protein (Clinical phase: WMD= –0.49, 95%CI –0.63 to –0.34, No phase: WMD= –0.60, 95%CI –0.96 to –0.24), and the urinary albumin excretion rate (UAER) (WMD= –148.75, 95%CI –238.01 to –59.48) was higher than that of the conventional treatment. (2) There were no significant differences between the two groups in the effect on the serum creatinine (Clinical phase: WMD= –8.43, 95%CI –18.15 to 1.29, No phase: WMD= –0.66, 95%CI –2.12 to 0.79) and creatinine clearance rate (WMD= 1.74, 95%CI –6.34 to 9.83). (3) Without enough data, it was uncertain to define the effect of tripterygium on lipids, blood pressure of the DN patients. (4) No severe adverse events or allergic reactions were reported. Conclusion Tripterygium may be a kind of medicine relatively safe and effective for diabetic nephropathy. However, the evidence is not b enough because of some low-quality trials and publication bias. Rigorously-designed, randomized, double-blind, and placebo-controlled trials of tripterygium for diabetic nephropathy are needed to further assess the effect.
Objective To carry out Meta analyses about the published literature that concerns Kaishi injection curing diabetic nephropathy, and to evaluate the efficacy and safety of Kaishi injection for diabetic nephropathy. Methods We searched the following databases: PubMed (1995 to 2010), EMCC (1995 to 2010), CBM (1995 to 2010), CNKI (1995 to 2010), and VIP (1989 to 2010) to collect randomized controlled trials (RCTs) of Kaishi injection curing diabetic nephropathy. The selection of studies, assessment of methodological quality and data extraction were performed independently by two reviewers. According to predefined inclusion and exclusion criteria Cochrane systematic review methods, the methodological quality assessment was undertaken, and meta-analyses were performed by using The Cochrane Collaboration’s RevMan 4.2.8 software. Evolution index were included: UAER, Scr, BUN, and 24 hours urinary protein.Results The literature included 19 RCTs with a total of 1 153 cases. Among them, 594 cases belonged to the treatment group and the control group included 559 ones. The studies of baseline data were comparable, and all reported that there were random methods but did not mention blinding and allocation concealment. Only one mentioned references to a listof random numbers by random grouping. The results of meta-analyses indicated that Kaishi injection was superior to routine treatment in decreasing UAER [WMD= – 77.86, 95%CI (– 85.64, – 70.08)], Scr [WMD= – 3.14, 95%CI (– 5.30, – 0.98)], BUN [WMD= – 0.71, 95%CI (– 1.13, – 0.29)], and 24 hours urinary protein [WMD= – 0.56, 95%CI (– 0.79, – 0.33)]. Conclusion The treatment of the diabetic nephropathy of Kaishi injection is superior to the conventional therapy. However, because of few high quality literature and limited sample size, further study is needed.
