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 xuezhikang for treating diabetic kidney disease. Methods We searched the Cochrane Central Register of Controlled Trials (Issue 3, 2008), MEDLINE (1980 to September 2008), EMbase (1980 to September 2008), CBMdisc (1990 to September 2008), and CNKI (1994 to September 2008). We also hand searched relevant journals and conference proceedings. Randomized controlled trials (RCTs) in which xuezhikang was used to treat diabetic kidney disease were collected. Then we screened the retrieved studies according to predefined inclusion and exclusion criteria, evaluated the quality of included studies, and performed metaanalyses by using The Cochrane Collaboration’s RevMan 4.2 software. Results Nine RCTs were included. Meta-analyses showed that xuezhikang was superior to routine treatment in decreasing 24-hour urinary protein (WMD –0.87, 95%CI –1.34 to –0.41), microalbuminuria (WMD –115.39, 95%CI –127.63 to –103.15), and urinary albumin excretion rate (WMD – 65.46, 95%CI –68.87 to –62.12); but xuezhikang had similar effects in reducing serum creatinine compared with routine treatment (WMD –5.42, 95%CI –11.06 to 0.21). Moreover, xuezhikang was more effective in regulating blood lipids, including TC (WMD –1.71, 95%CI –2.39 to –1.03), TG (WMD –0.96, 95%CI –1.46 to –0.46), LDL-C (WMD –1.01, 95%CI –1.64 to –0.38), and HDL-C (WMD 0.22, 95%CI 0.09 to 0.36). Xuezhikang was not superior to routine treatment in improving fasting blood sugar (WMD -0.01, 95%CI -0.49 to 0.47), but was more effective in improving 2 h-BS (WMD –1.10, 95%CI –1.35 to –0.85) and HbA1c (WMD –0.41, 95%CI –0.56 to –0.27). No significant adverse effects or allergic reactions were reported. Conclusions The evidence currently available shows that xuezhikang may decrease 24-hour urinary protein, microalbuminuria, serum creatinine, regulate blood lipids, and adjust blood glucose. Due to a high risk of selection bias and detection bias in the included studies, the evidence is insufficient to determine the effect of xuezhikang. Further large-scale trials are required to define the role of xuezhikang in the treatment of diabetic kidney disease.
Objective To assess the efficacy and safety of Sodium ferulate for diabetic kidney disease. Methods Based on the principles and methods of Cochrane systematic reviews, we searched the Cochrane Central Register of Controlled Trials (Issue 4, 2008), MEDLINE (1996 to December 2008), EMbase (1980 to December 2008), CBMdisc (1990 to December 2008), CNKI (1994 to December 2008) and VIP (1989 to December 2008). And we also hand searched relevant journals and conference proceedings. We evaluated the risk of the bias of the included RCTs according to the Cochrane Handbook for Systematic Reviews of Interventions Version 5.0.1. The Cochrane Collaboration’s software RevMan 5.0 was used for meta-analysis. Results Thirty-nine RCTs were enrolled in the review, including 2 351 patients with type 2 diabetic kidney disease met the inclusion criteria. Most of these trials were small and of low quality with a high risk of bias. The results of meta-analysis showed that ① Sodium ferulate was better on attenuating UAER (WMD=– 42.92, 95%CI – 52.61 to – 33.23), 24 hours urinary protein (WMD=– 0.11, 95%CI – 0.16 to – 0.05), BUN (WMD=– 0.76, 95%CI – 1.04 to – 0.46) and Scr (WMD=– 8.38, 95%CI – 11.81 to – 4.94); Sodium ferulate was better on the regulation of FBG and 2 h-BG of clinical DKD (WMD= – 2.39, 95%CI – 3.23 to – 1.54), but not superior to routine treatment on the improvement of HbA1c (WMD= – 0.12, 95%CI – 0.27 to 0.02) and 2 h-BG of early DKD (WMD= – 0.22, 95%CI – 0.49 to 0.04); Sodium ferulate was better on the improvement of SBP and MAP, however, Sodium ferulate was not superior to routine treatment on the improvement of DBP; Sodium ferulate was better on the improvement of TC (WMD=– 0.70, 95%CI – 1.01 to – 0.39), HDL-c (WMD= 0.14, 95%CI 0.06 to 0.22) and TG of clinical DKD (WMD=– 0.96, 95%CI – 1.49 to – 0.43), but not superior to routine treatment on the improvement of TG of early DKD (WMD=– 0.12, 95%CI – 0.28 to 0.04); Sodium ferulate was better on the improvement of serum endothelin (WMD=– 18.72, 95%CI – 25.20 to – 12.23) and urinary endothelin (WMD=– 8.55, 95%CI – 10.92 to – 6.18). Only 8 studies mentioned sodium ferulate during treatment no adverse reactions or side effects, reportedly found in a study of mild and transient headache and a study of fatigue and dizziness. We have not seen the serious adverse events. Conclusions Current evidence demonstrates that Sodium ferulate has certain effect and relatively safe in treating patients with diabetic kidney disease.Due to the heterogeneity and the high risk of bias in included studies,the evidence is insufficient to determine the effect of sodium ferulate.Further large-scale trials are required to define the role of sodium ferulate in the treatment of DKD.
ObjectiveTo systematically review the independent physical risk factors associated with diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus. MethodsWe searched MEDLINE, EMbase, CBM, CNKI and VIP for all studies about the independent physical risk factors associated with diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus up to December 2012. Two reviewers independently screened studies according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then meta-analysis was conducted using RevMan 5.2 software. ResultsA total of 11 studies involving 12 957 patients with type 2 diabetes were included. Of these 11 studies, 9 were cross-sectional studies, two were cohort studies, and one was case-control study. The results showed that:the main physical factors associated with DKD were:duration of diabetes (OR=1.11, 95%CI 1.05 to 1.18), waist circumference (OR=1.02, 95%CI 1.00 to 1.04), fasting glucose (OR=1.11, 95%CI 1.07 to 1.16), glycosylated hemoglobin (OR=1.20, 95%CI 1.06 to 1.36), systolic blood pressure (OR=1.03, 95%CI 1.02 to 1.05), diastolic blood pressure (OR=2.41, 95%CI 1.15 to 4.64), triglycerides (OR=1.24, 95%CI 1.02 to 1.51), high-density lipoprotein (OR=0.558, 95%CI 0.369 to 0.844), blood uric acid (OR=1.005, 95%CI 1.002 to 1.009), blood urea nitrogen (OR=1.58, 95%CI 1.37 to 1.82), past history of kidney disease (OR=3.26, 95%CI 1.20 to 8.87) and family history of kidney disease (OR=1.83, 95%CI 1.29 to 2.60). ConclusionCurrent evidence shows that multiple physical factors were associated with the development of type 2 diabetic kidney disease. However, due to the limited quantity and quality of the included studies, more high quality studies are needed to verify the conclusion.
Diabetic kidney disease (DKD) is a major complication of diabetes mellitus. One third of patients with advanced diabetes mellitus can develop to uremia, which seriously endangers people’s health. In recent years, with the improvement of people’s living standards and the increasing incidence of diabetes, it has become the main cause of end stage renal disease in China. Over the past two decades, the understanding of diagnosis and treatment of DKD has been improved, such as putting forward the new concept of normoalbuminuric DKD and developing a variety of new anti-diabetic drugs. However, at present, the basic strategies of DKD treatment are still lifestyle modification, glucose control, blood pressure control and lipid control.
The incidence of chronic kidney disease is increasing worldwide, which greatly increases the risk of end-stage renal disease. It is particularly important to find out the risk factors for the development and progression of chronic kidney disease. Whether gender is a risk factor for the progression of kidney disease remains controversial with inconsistent results in human cohort studies with diabetic or non-diabetic kidney disease. In most of the studies, women seem to exhibit certain gender advantages. Sex hormones, renal hemodynamics and lifestyle differences may play an important role. The underlying mechanism of gender affecting the progression of kidney disease deserves further exploration. This article reviews the gender differences and possible mechanisms in diabetic and non-diabetic chronic kidney disease, in order to provide reference for future research.
