  • Tongxinluo Capsule for Diabetic Kidney Disease: A Systematic Review

    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.

  • Statins for Early Diabetic Kidney Disease: A Systematic Review

    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

  • Medicinal Charcoal for Chronic Kidney Disease: A Systematic Review

    Objective To assess the efficacy and safety of prescribing medicinal charcoal for treatment of adult chronic kidney disease. Methods We searched the Cochrane Controlled Trial Register (The Cochrane Library Issue 1, 2009), MEDLINE (1950 to January 2009), EMbase (1980 to January 2009), and Chinese Biomedical Database (1977 to January 2009) to screen randomized controlled trials (RCTs) concerning use of medicinal charcoal for treatment of adult chronic kidney disease. We evaluated the bias risk of the included RCTs according to the Cochrane Handbook for Systematic Reviews of Interventions Version 4.2.2.The Cochrane Collaboration’s software RevMan 5.0 was used for meta-analysis. Results Seven trials involving 347 patients met the criteria. Meta-analysis showed: (1) Medicinal charcoal was better than routine treatment on the improvement of blood urea nitrogen [MD= –0.69, 95%CI (–1.13, –0.24), P=0.002], serum creatinine [MD= – 0.51, 95%CI (–0.94, – 0.08), P=0.02] and the mean change of glomerular filtration rate per month (Plt;0.001). Compared with routine treatment, medicinal charcoal had similar effects on the improvement of 24 hours urinary protein and the mean change of blood pressure; (2) Compared with placebo, and medicinal charcoal was not superior to placebo in improving the incidence of end stage kidney diseases, serum creatinine, creatinine clearance rate, 24 hour urinary protein (Pgt;0.05); (3) Adverse events with constipation, flatulenceand nausea occurred to medicinal charcoal groups. Conclusion Overall, the evidence is not b enough, and more large, high-quality randomized controlled trials are needed to confirm or refute the available evidence.

  • Xuezhikang for Diabetic Kidney Disease: A Systematic Review of Randomized Controlled Trials

    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.

  • Comparison of APACHEⅡ and Ⅲ Scoring System in Predicting the Prognosis of Patients with Acute Kidney Injury and Multiple Organ Dysfunction Syndrome in ICU

    Objective To compare the clinical value of Acute Physiology and Chronic Health Evaluation ( APACHE) Ⅱ / Ⅲ scoring system in predicting the prognosis of patients complicated with acute kidney injury ( AKI) and multiple organ dysfunction syndrome ( MODS) in ICU. Methods 318 patients with AKI and MODS treated with continuous blood purification in ICU fromJanuary 2004 to June 2010, were evaluated with APACHE Ⅱ and APACHEⅢ and analyzed retrospectively. The area under the receiveroperating characteristic curve ( AUC) and the Lemeshow-Hosmer goodness-of-fit of APACHEⅡ and Ⅲ were assessed. Results Mean scores and predicted hospital mortality of APACHEⅡ and Ⅲ were all significantly lower in the survival group than those in the non-survival group ( P lt; 0. 01) . The AUC were 0. 782 for APACHEⅡ, and 0. 755 for APACHEⅢ, with Youden’s indexes of 46. 4% and 36. 7% , respectively. Hosmer-Lemeshow test showed the calibration of the two systems was reasonable. Conclusion APACHEⅡ and Ⅲ are both good for predicting the severity and prognosis of patients complicated with AKI and MODS in ICU but APACHEⅡ is superior in clinical practice.

  • Pulmonary Arterial Pressure in Patients with Predialysis Chronic Kidney Disease and Its Relationship to Cardiac Structure and Function

    Objective To explore the pulmonary arterial pressure level in patients with predialysis chronic kidney disease ( CKD) and its relationship to cardiac structure and function. Methods 397 patients with predialysis CKD and 50 healthy subjects were enrolled. Cardiac structure was evaluated by Doppler echocardiography. Glomerular filtration rate ( GFR ) were assessed by radiant 99mTc-DTPA.Differences of PAP, BNP, LA, IVST, LVDd, LVDs, LVEF, LVMI and the correlation of PAP with cardiac structure and function were examined. Results The PAP level in the predialysis CKD patients was much higher than that in the healthy subjects [ ( 33. 13 ±9. 00) mm Hg vs. ( 29. 43 ±3. 71) mmHg, P lt;0. 01] .18. 9% of the CKD patients were complicated with pulmonary hypertension. PAP was higher in the CKD patients in stages 4-5 than those CKD patients in stages 1-3 [ ( 35. 90 ±9. 34) mmHg vs. ( 32. 08 ±8. 62)mmHg, P lt;0. 01) ] , so as to the prevalene of pulmonary hypertension ( 21. 60% vs. 13. 47% , P lt;0. 01) .Compared with the healthy, the level of lnBNP [ ( 3. 59 ±1. 63) pg/mL vs. ( 2. 88 ±1. 51) pg/mL, P lt;0. 01] , LA [ ( 40. 42 ±6. 77) mmvs. ( 36. 75 ±4. 94) mm, P lt; 0. 01) ] , LVPW [ ( 9. 55 ±1. 96) mm vs.( 8. 54 ±0. 88) mm, P lt; 0. 01) ] , IVST [ ( 9. 76 ±1. 75) mm vs. ( 8. 71 ±0. 90) mm, P lt; 0. 01) ] , LVMI[ ( 105. 61 ±36. 47) g/m2 vs. ( 87. 41 ±17. 08) g/m2 , P lt; 0. 01) ] were all much higher. There was a negative correlation between PAP and GFR( r = - 0. 461, P lt;0. 01) , and positive correlations between PAP and LA ( r=0. 491, P lt; 0. 01) , LVPW ( r =0. 298, P lt;0. 01) , IVST ( r = 0. 613, P lt;0. 01) , lnBNP ( r =0. 536, P lt;0. 01) , LVMI ( r = 0. 382, P lt;0. 01) . LVMI and lnBNP were both independent risk factors of PAP. The regression equation: y = 16. 447 + 0. 105x1 + 1. 724x2 ( F = 23. 482, P = 0. 000) , y: PAP( mm Hg) , x1 : LVMI( g/m2 ) , x2 : lnBNP( pg/mL) . Conclusions Pulmonary hypertension is a common morbidity of predialysis CKD patients, and deteriorates with degression of renal function. PAP is related to indexes of cardiac structure ( LVMI, LA, LVPW, IVST) and index of cardiac function ( lnBNP) . LnBNP and LVMI are independent risk factors of PAP.

  • Clinical Predictive Score for Acute Kidney Injury after Cardiac Surgery in Adults

    Objective To analyze risk factors of acute kidney injury (AKI) after cardiac surgery in adults and develop a clinical score system to predict postoperative AKI. Methods Clinical data of 3 500 consecutive patients undergoing cardiac surgery from June 2010 to April 2011 in Beijing Anzhen Hospital of Capital Medical University were retrospectively analyzed. According to whether they had postoperative AKI,all these patients were divided into AKI group and non-AKI group. AKI group was consisted of 1 407 patients (40.2%) with a mean age of 58±12 years,including 1 004 male patients (71.4%). The non-AKI group was consisted of 2 093 patients (59.8%) with a mean age of 55±13 years,including 1 259 male patients (60.2%). Predictive score system of postoperative AKI was established by univariate analysis between the AKI and non-AKI group and multivariate logistic regression and then verified. Results The predictive score system was as followed:male gender (2 points),every 5 years older than 60 years (1 point),diabetes mellitus (2 points),preoperative use of angiotensin converting enzyme inhibitor or angiotensin AT1 receptor blocker (1 point),every 10 ml / (min·1.73 m2) of preoperative estimated glomerular filtration rate (eGFR) under 90 ml / (min·1.73m2) (1 point),preoperative NYHA class Ⅳ (3 points),cardiopulmonary bypass time>120 minutes (2 points),intraoperative hypotension duration>60 minutes (2 points),postoperative hypotension duration>60 minutes (3 points),postoperative peak dosage of intravenous furosemide>100 mg/day (3 points),postoperative peak dosage of intravenous furosemide 60-100 mg/day (2 points),and postoperative mechanical ventilation time>24 hours (2 points). The predictive score system presented a good discrimination ability with the area under the receiver operating characteristic(ROC)curve of 0.738 with 95% CI 0.707 to 0.768,while it also presented a good calibration with Hosmer-Lemeshow statistic (P=0.305). Conclusion A clinical predictive score system for AKI after cardiac surgery in adults is established,which may help clinicians implement early preventive interventions.

  • Application of Acute Kidney Injury Criteria and Classification to Predict Mortality Following Cardiovascular Surgery

    Abstract: Objective To evaluate the incidence and prognosis of postoperative acute kidney injury (AKI) in patients after cardiovascular surgery, and analyse the value of AKI criteria and classification using the Acute Kidney Injury Network (AKIN) definition to predict their in-hospital mortality. Methods A total of 1 056 adult patients undergoing cardiovascular surgery in Renji Hospital of School of Medicine, Shanghai Jiaotong University from Jan. 2004 to Jun. 2007 were included in this study. AKI criteria and classification under AKIN definition were used to evaluate the incidence and in-hospital mortality of AKI patients. Univariate and multivariate analyses were used to evaluate preoperative, intraoperative, and postoperative risk factors related to AKI. Results Among the 1 056 patients, 328 patients(31.06%) had AKI. In-hospital mortality of AKI patients was significantly higher than that of non-AKI patients (11.59% vs. 0.69%, P<0.05). Multivariate logistic regression analysis suggested that advanced age (OR=1.40 per decade), preoperative hyperuricemia(OR=1.97), preoperative left ventricular failure (OR=2.53), combined CABG and valvular surgery (OR=2.79), prolonged operation time (OR=1.43 per hour), postoperative hypovolemia (OR=11.08) were independent risk factors of AKI after cardiovascular surgery. The area under the ROC curve of AKIN classification to predict in-hospital mortality was 0.865 (95% CI 0.801-0.929). Conclusion Higher AKIN classification is related to higher in-hospital mortality after cardiovascular surgery. Advanced age, preoperative hyperuricemia, preoperative left ventricular failure, combined CABG and valvular surgery, prolonged operation time, postoperative hypovolemia are independent risk factors of AKI after cardiovascular surgery. AKIN classification can effectively predict in-hospital mortality in patients after cardiovascular surgery, which provides evidence to take effective preventive and interventive measures for high-risk patients as early as possible.

  • Analysis of Risk Factors for Acute Kidney Injury after Aortic Arch Replacement Surgery

    Abstract: Objective To determine the risk factors for acute kidney injury (AKI) after thoracic aortic arch replacement surgery under deep hypothermic circulatory arrest (DHCA). Methods We retrospectively analyzed the clinical data of 139 patients who underwent thoracic aortic arch replacement surgery under DHCA between January 2004 and December 2008 in Beijing Anzhen Hospital Affiliated to Capital University of Medical Sciences. The patients were divided into two gro-ups according to whether AKI occurred after thoracic aortic arch replacement surgery. In the AKI gro-up (n=48), there were 39 males and 9 females with an age of 57.67±9.56 years. In the normal renal function gro-up (n=91), there were 69 males and 22 females with an age of 41.30±13.37 years. We observed the clinical data of the patients in both gro-ups, including left ventricular ejecting fraction (LVEF) before operation, diameter of the left ventricle, diameter of the ascending aorta, renal function, cardiopulmonary bypass time, aortic crossclamp time, and DHCA time. The risk factors for AKI and death after operation were evaluated by univariate analysis and stepwise logistic regression analysis. Results Among all the patients, AKI occurred in 48 (34.53%), 17 (12.23%) of whom underwent continuous renal replacement therapy (CRRT). Respiratory failure occurred in 27 patients (19.42%). Twentynine patients (20.86%) had cerebral complications, including temporary cerebral dysfunction in 26 patients and permanent cerebral dysfunction in 3 patients. In all the patients, 14 (10.07%) died, including 4 patients of heart failure, 9 patients of multiple organ failure, and 1 patient of cerebral infarction. There were 3 (3.30%)deaths in the normal renal function gro-up and 11 (22.92%) deaths in the AKI gro-up with a significant difference of mortality rate between the two gro-ups (P=0.011). A total of 118 patients were followed -up and 7 were lost. The follow-up time was from 5 to 56 months with an average time of 42 months. During the follow-up period, 7 patients died, including 3 patients of heart failure, 2 patients of cerebral apoplexy, and 2 patients of unknown reasons. The logistic regression analysis revealed that creatinine level was greater than 13260 μmol/L before operation (OR=1.042, P=0.021) and respiratory failure (OR=2.057, P=0.002) were independent determinants for AKI after the operation. Conclusion AKI is the most common complication of thoracic aortic arch replacement surgery under DHCA, and is the risk factor of mortality after the surgery. It is important to enhance perioperative protection of the renal function.

  • Application of the Clinical Score Developed by Cleveland University to Predict Acute Renal Failure after Cardiac Surgery in Chinese Patients

    Abstract: Objective To investigate the application value of the Clinical Score developed by Cleveland University in predicting the occurrence ratio of acute renal failure in Chinese patients after cardiac surgery. Methods A total of 456 adult patients , 230 males and 226 females , with cardiac surgery during August 2008 to July 2009 were included in our study. Their age ranged from 18 to 88 years with an average age of 56.7 years. Before the surgery, Clinical Score was used to predict acute renal failure after cardiac surgery. Based on the score of ≤5, 610, or ≥11, the patients were divided into group Ⅰ (n=401), group Ⅱ (n=42) and group Ⅲ (n=13). The occurrence rate of acute kidney injury (AKI), continuous renal replacement therapy in hospital, multiple organ failure, mortality and other clinical indexes were compared among the 3 groups. Results Occurrence ratio of AKI of group Ⅰ, Ⅱ, Ⅲ was respectively 2.74%, 28.57% and 76.92% (χ2=73.004, P=0.000). Continuous renal replacement therapy rate was respectively 0.50%, 9.52%, and 38.46% (χ2=36.939, P=0.000). Multiple organ failure rate was respectively 0.50%, 4.76%, and 23.08% (χ2=19.694, P=0.000). Mortality rate was respectively 0.25%, 2.38%, and 15.38% (χ2=14.061, P=0.001). There were significant differences among the three groups. Conclusion The Clinical Score to Predict Acute Renal Failure developed by Cleveland University can effectively predict the occurrence rate of acute renal failure in the Chinese patients after cardiac surgery before the operation. Therefore, corresponding preventive methods can be taken for highrisk patients.
