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.
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.
Objective To assess the clinical efficacy of Cordyceps sinensis in the treatment of chronic kidney diseases. Methods Randomized or quasi-randomized controlled trials (RCTs or quasi-RCTs) were identified from MEDLINE (1996 to Oct. 2005), EMbase (1984 to Oct. 2005), The Cochrane Central Register of controlled Trials (Issue 3, 2005) and CBMdisc (1978 to Oct. 2005). We also handsearched related published and unpublished data and their references. Data were extracted and evaluated by two reviewers independently with a designed extraction form. RevMan4.2.7 software was used for data analysis. Results One RCT and 5 quasi-RCTs involving 434 patients were included. Results of meta-analysis were presented as follows: ① Response rate: five studies showed that, compared with the blank control group, significant differences were observed after the treatment with Cordyceps (RR 2.13, 95%CI 1.06 to 4.26); one study showed that there was no difference between Cordyceps and Shenyankangfu tablet (RR 2.17, 95%CI 0.73 to 6.460). ② Total effective rate: five studies showed that, compared with the blank control group, significant differences were observed after the treatment with Cordyceps (RR1.94, 95 %CI 1.14 to 3.30); one study showed that there was no difference between Cordyceps and Shenyankangfu tablet (RR 1.39, 95%CI 0.89 to 2.16). ③ Adverse reactions: adverse reactions were rare only with mild symptoms. Conclusions Cordyceps sinensis may improve the response rate and total effective rate of chronic kidney diseases. More high quality trials are required.
Studies of evidence-based medicine have provided much important evidence, clarified problems, and guided the clinical practice in the treatment of renal diseases. As examples, several therapeutic problems in renal hypertension, renal anemia and low protein diet for the patients with chronic kidney disease are discussed in this paper.
ObjectiveTo observe whether proteinuria is relate to the decline of residual renal function (RRF) in peritoneal dialysis (PD) patients. MethodsThis is a prospective cohort study including 45 PD patients (underwent PD between January 2011 and January 2013) with a 12-month follow-up. All the patients were divided into 2 groups with respect to the initial proteinuria level: massive proteinuria group A (n=20) and non-massive proteinuria group B (n=25) at baseline. We established regression models to do univariate analysis and multivariate analysis of the relationship between the decline of RRF≥50% of baseline and the indices of age, sex, PD-associated peritonitis, baseliner residual glomerular filtration rate (rGFR), initial proteinuria, and use of ACEI/ARB. ResultsThe primary outcome (RRF>50% of baseline) at 12 months was 65% in group A, and 80% in group B (P<0.05). Based both on the results of univariate and multivariate Cox regression analysis, non-massive proteinuria and higher rGFR at baseline were factors to protect RRF from decline (P<0.05). ConclusionThe study demonstrates that massive proteinuria and lower rGFR at baseline may be associated with a rapid decline of RRF in PD patients. Treatment aimed at reducing albuminuria may lead to protect RRF and improve life quality of patients.
ObjectiveTo collect the nutrition data in patients with chronic kidney disease (CKD) from stage 1 to 4 and provide the basis for further intervention by analyzing the specific problems of the patients. MethodsA total of 132 CKD patients from stage 1 to 4 were enrolled between December 2012 and December 2013. Nutritionists used inbodyS10ww as a body composition analyzer to test the patients. The data from inbodyS10ww and laboratory indexes were analyzed on marasmus, overweight and obesity, risk of malnutrition, malnutrition, anemia and hypoalbuminemia. ResultsThe percentage of marasmus in those CKD patients was 3.0%, overweight and obesity was 39.4%, the risk of malnutrition was 22.7%, malnutrition was 19.7%, anemia was 34.1%, and hypoalbuminemia was 9.8%. ConclusionOur search shows that combining the application of anthropometry and laboratory indexes can evaluate the nutritional status of patients with CKD. The most common nutritional problems in CKD patients include malnutrition, overweight and obesity, risk of malnutrition, and anemia. As for hypoalbuminemia, it is low in early CKD patients.
Objective To explore the hormone medication compliance in children with chronic kidney disease (CKD) and analyze its influencing factors. Methods Between May and December 2013, 96 children were investigated by questionnaires about medication compliance when they were out of the hospital. Then we analyzed the influencing factors for medication compliance. All the data were analyzed by SPSS 19.0 software. Results Of these 96 children, medication nonadherence accounted for 52% (50). The main guardian, educational level of the father, educational level of the mother, residence, duration of illness, time of hospitalization, and understanding of the treatment plan played significant roles in causing different medication compliance among these children (P＜0.05). Logistic regression analysis showed that duration of illness [OR=2.204, 95%CI (1.253, 3.875), P=0.006], residence [OR=2.615, 95%CI (1.0 23, 6.687), P=0.045] and the mother’s educational level [OR=0.147, 95%CI (0.028, 0.788), P=0.025] were the independent factors for medication compliance. Conclusions According to the survey, hormone medication compliance in children with chronic kidney disease is not satisfying. We should strengthen the health education in children and their parents, and adopt specific interventions to enhance the medication compliance so as to effectively control the disease and delay the progression.
ObjectivesTo evaluate the methodological bias and the reliability of the conclusions of systematic reviews (SRs) of lanthanum carbonate in the treatment of chronic kidney disease with hyperphosphatemia. MethodsWe electronically searched databases including PubMed, EMbase, The Cochrane Library, PROSPERO, CNKI, CBM, WanFang Data and VIP to collect systematic reviews and meta-analysis about lanthanum carbonate in the treatment of chronic kidney disease with hyperphosphatemia from inception to August 31st, 2016. Two reviewers independently screened literature and extracted data, then AMSTAR tool was used to assess the methodological quality of included studies and the GRADE tool was used to grade the evidence quality of outcome measures included in the SRs. ResultsA total of eight relevant SRs were included and containing three main outcome measures. The assessment results of AMSTAR tool suggested that:four SRs were of high quality, and the other four were of medium quality. GRADE results showed:for serum phosphorus level, compared with placebo, the quality of the evidence of three SRs were medium, low and very low; compared with calcium carbonate or conventional phosphorus binder, four SRs were low, low, low and very low; compared with sevelamer, one SR was low. For serum calcium level, compared with placebo, the quality of the evidence of three SRs were high, medium and low, respectively; compared with calcium carbonate or conventional phosphorus binder, five SRs were low, low, low, very low and very low; compared with sevelamer, one SR was very low. For serum iPTH level, compared with placebo, the quality of the evidence of three SRs were medium, low and very low; compared with calcium carbonate or conventional phosphorus binder, five SRs were medium, low, low, very low and very low; compared with sevelamer, one SR was low. ConclusionAt present, methodological quality assessment for the treatment of hyperphosphatemia in chronic kidney disease with lanthanum carbonate is generally not high and the level of evidence for the conclusion is generally low. In drug safety, especially in the occurrence of adverse events of the digestive system is still controversial, and a large amount of high quality experimental is needed to demonstrate the safety of its long-term use. Clinicians need to be cautious in using these evidence to make clinical decisions.
Objective To investigate the prevalence and risk factors of sleep-disordered breathing (SDB) in patients with different severity of chronic kidney diseases (CKD). Methods A total of 144 patients of non-dialysis CKD patients in nephrology unit were recruited in the study. The patients were divided into CKD 1-2 period, CKD 3-4 period, and CKD5 period according to the severity of renal function. Results The prevalence of moderate SDB in CKD 1-2 period, CKD 3-4 period and CKD5 period were 30.0%, 53.5% and 60.5%, respectively (P=0.03), the prevalence of nocturnal hypoxemia were 23.3%, 56.3% and 65.1%, respectively ( P=0.001), and the prevalence of excessive daytime sleepiness (EDS) were 33.3%, 57.7% and 62.8%, respectively (P=0.032). Logistic regression analysis showed that age, male, body mass index (BMI), hypertension, diabetes and heart failure were independent risk factors for CKD merged with moderate to severe SDB, and the highest risk factor was heart failure (OR=7.034, 95%CI 1.255-39.420). Compared with CKD 1-2 period and CKD 3-4 period, the risk degree of CKD5 period was higher (OR=3.569 95%CI 1.324-9.620). Correlation analysis showed that glomerular filtration rate (eGFR) was negatively correlated with sleep apnea-hypopnea index (AHI) (r=–0.327, P=0.000). Conclusions There is a high prevalence of SDB (predominantly obstructive) in CKD patients and the increased risk of SDB is significantly associated with decreased eGFR among these patients. Associated comorbidities in CKD patients, especially for cardiac dysfunction, are important risk factors for SDB.
Objective To explore the relationship between 25-hydroxy vitamin D [25(OH)D] and metabolic syndrome (MS) in non-dialysis patients with stage 3–5 chronic kidney disease (CKD). Methods Between January 2014 and May 2015, a total of 61 non-dialysis patients with stage 3–5 CKD were included. The patients’ height, weight, blood lipid, levels of 25(OH)D and serum creatinine were conducted. The relationship between 25(OH)D and MS was analyzed. Results The average level of 25(OH)D was (39.99±17.66) nmol/L. Normal level (≥75 mmol/L) of 25(OH)D was observed in 3.3% (2/61) of the patients, insufficiency of 25(OH)D (≥37.5 nmol/L and <75 nmol/L) was observed in 50.8% (31/61), and deficiency (<37.5 nmol/L) was observed in 45.9% (28/61). The prevalence of MS was 67.2% ( 41/61). The body mass index (BMI), proportion of hypertension, proportion of diabetes mellitus, level of triglyceride in the MS group were higher than those in the non-MS group, while the levels of high-density lipoprotein and 25(OH)D were lower in the MS group than those in the non-MS group, and the differences were statistically significant (P<0.05). The patients’ BMI, proportion of hypertension, level of triglyceride and proportion of MS in the 25(OH)D deficiency group were higher than those in the 25(OH)D non-deficiency group, meanwhile, the level of high-density lopoprotein was lower in the 25(OH)D deficiency group than that in the 25(OH)D non-deficiency group, and the differences were statistically significant (P<0.05). Serum 25(OH)D level was correlated negatively with BMI (r=–0.35, P=0.006) and the level of triglyceride (r=–0.16, P=0.039), and correlated positively with the level of high-density lipoprotein (r=0.18, P=0.026). Conclusions Low level of 25(OH)D and MS are both of high incidence rate in non-dialysis patients with stage 3–5 CKD. 25(OH)D is associated with MS.
