Background: The correlation between soluble Klotho (sKlotho) level and vascular calcification (VC) in patients with chronic kidney disease (CKD) remains controversial. Using meta-analysis, we aimed to address this controversy and assess the feasibility of applying sKlotho as a biomarker for VC.Methods: Medical electronic databases were thoroughly searched for eligible publications on the association between sKlotho level and VC in CKD patients. Effectors, including correlation coefficients (r), odds ratios (ORs), hazard ratio (HR) or β-values, and 95% confidence intervals (CIs) were extracted and combined according to study design or effector calculation method. Pooled effectors were generated using both random-effects models and fixed-effects models according to I2-value. Origin of heterogeneity was explored by sensitivity analysis and subgroup analysis.Results: Ten studies with 1,204 participants from a total of 1,199 publications were eligible and included in this meta-analysis. The combined correlation coefficient (r) was [−0.33 (−0.62, −0.04)] with significant heterogeneity (I2 = 89%, p < 0.001) based on Spearman correlation analysis, and this significant association was also demonstrated in subgroups. There was no evidence of publication bias. The combined OR was [3.27 (1.70, 6.30)] with no evidence of heterogeneity (I2 = 0%, p = 0.48) when sKlotho was treated as a categorical variable or [1.05 (1.01, 1.09)] with moderate heterogeneity (I2 = 63%, p = 0.10) when sKlotho was treated as a continuous variable based on multivariate logistic regression. No significant association was observed and the pooled OR was [0.29 (0.01, 11.15)] with high heterogeneity (I2 = 96%, p < 0.001) according to multivariate linear regression analysis. There was an inverse association between sKlotho and parathyroid hormone levels. The combined coefficient (r) was [−0.20 (−0.40, −0.01)] with significant heterogeneity (I2 = 86%, p < 0.001), and without obvious publication bias. No significant association was found between sKlotho and calcium or phosphate levels.Conclusion: There exists a significant association between decreased sKlotho level and increased risk of VC in CKD patients. This raises the possibility of applying sKlotho as a biomarker for VC in CKD populations. Large, prospective, well-designed studies or interventional clinical trials are required to validate our findings.

Background Although the relationship between a history of kidney stones and chronic kidney disease (CKD) has been explored in many studies, it is still far from being well understood. Thus, we conducted a meta-analysis of studies comparing rates of CKD in patients with a history of kidney stones. Methods PubMed, EMBASE, and the reference lists of relevant articles were searched to identify observational studies related to the topic. A random-effects model was used to combine the study-specific risk estimates. We explored the potential heterogeneity by subgroup analyses and meta-regression analyses. Results Seven studies were included in this meta-analysis. Pooled results suggested that a history of kidney stones was associated with an increased adjusted risk estimate for CKD [risk ratio (RR), 1.47 95% confidence interval (CI) [1.23–1.76])], with significant heterogeneity among these studies (I2 = 93.6%, P < 0.001). The observed positive association was observed in most of the subgroup analyses, whereas the association was not significant among studies from Asian countries, the mean age ≥50 years and male patients. Conclusion A history of kidney stones is associated with increased risk of CKD. Future investigations are encouraged to reveal the underlying mechanisms in the connection between kidney stones and CKD, which may point the way to more effective preventive and therapeutic measures.

An association between liver stiffness, a surrogate measure of liver fibrosis, and chronic kidney disease (CKD) in patients with nonalcoholic fatty liver disease (NAFLD) has been proposed. However, most studies were small and had low statistical power. We systematically searched PubMed-MEDLINE and Scopus from inception to August 2021 for cross-sectional or cohort studies reporting the association between liver stiffness diagnosed by vibration controlled transient elastography (VCTE) and renal dysfunction. The primary outcome was CKD, defined as a composite of urinary albumin to creatinine ratio (UACR) ≥ 30 mg/g and estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2. Measures of association from individual studies were meta-analyzed using random effects models. Of the 526 titles initially scrutinized, 7 cross-sectional studies fulfilled the criteria and were included. For CKD, risk was higher in patients with liver fibrosis assessed by VCTE, compared with patients without (n = 5 studies: OR 2.49, 95% CI 1.89–3.29; test for overall effect z = 6.475, p < 0.001). When increased UACR was considered as an outcome, elevated liver stiffness was associated with a significantly increased risk as well (n = 3 studies: OR 1. 98 95% CI 1.29–3.05; test for overall effect z = 3.113, p = 0.002). Neither analysis showed significant heterogeneity (I2 = 0% and I2 = 46.5%, respectively for the two outcomes). This meta-analysis indicates that elevated liver stiffness is associated with increased odds of kidney outcomes among patients with NAFLD. Wider use of VCTE to screen for advanced fibrosis might help identify patients at risk of end-stage renal disease.

Objective. Over decades, numerous inconsistent studies are reported on the relationship between soluble α-Klotho and renal function in patients with chronic kidney disease (CKD). This study aims to perform a meta-analysis to figure out the correlations between soluble α-Klotho and renal function in patients with CKD. Materials and Methods. We searched medical and scientific literature databases, PubMed and EMBASE (from the inception to October 2017), for publications that reported studies on associations between soluble α-Klotho and renal function in patients with CKD. Only publications in English were extracted. Summary correlation coefficient (r) values were extracted from each study, and 95% confidence intervals (CIs) were calculated. Publication bias was tested, and sensitivity and subgroup analyses were performed to investigate potential heterogeneity. Results. Of 611 studies, 9 publications with 1457 patients were included into the analysis. The following data were extracted from the literature: first author, year of publication, research region, research index, sample size, average age and Pearson or Spearman correlation coefficient, study design, the αKlotho/FGF23 assays utilized, full length, or the C-terminal fragment of FGF23. The pooled r between α-Klotho and estimated glomerular filtration rate (eGFR), FGF-23 were 0.35 (95%CI, 0.23~0.46, and P<0.05), -0.10 (95%CI, -0.19~-0.01, and P<0.05) with remarkable significance, indicating moderate heterogeneity. There was no significant heterogeneity between subgroups in analyses of α-Klotho and eGFR stratified by research region, mean age, and eGFR, but heterogeneity exists in analyses of α-Klotho and FGF-23 stratified by research region. There was no significant correlation between a-klotho and Ca and PTH and PHOS. There was no evidence of publication bias with Egger’s test (p=0.360) or with Begg’s test (p=0.902) and the distribution of funnel plots was symmetrical in all of our analysis. Conclusions. There exists a significant positive correlation between soluble α-Klotho and eGFR in patients with CKD. Also, a significant negative correlation between α-Klotho and FGF23 levels is proven. This raises hope to employ αKlotho and FGF23 as early biomarkers of CKD. However, further large prospective follow-up researches are needed to validate this hypothesis and to explore whether maintaining or elevating the Klotho level could improve renal function and complications in CKD patients.

Abstract Background and Aims Patients with chronic kidney disease (CKD) undergoing dialysis are at a particularly high risk of cardiovascular mortality and morbidity. This systematic review and meta-analysis aimed to evaluate the benefits and harms of aldosterone antagonists, both non-selective (spironolactone) and selective (eplerenone), in comparison to control (placebo or standard care) in patients with CKD requiring haemodialysis or peritoneal dialysis. Method We searched the Cochrane Kidney and Transplant Register of Studies up to 29 July 2019 using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register Search Portal and ClinicalTrials.gov. We included individual and cluster randomised controlled trials (RCTs), cross-over trials, and quasi-RCTs that compared aldosterone antagonists with placebo or standard care in patients with CKD requiring dialysis. We used a random-effects model meta-analysis to perform a quantitative synthesis of the data. We used the I2 statistic to measure heterogeneity among the trials in each analysis. We indicated summary estimates as a risk ratio (RR) for dichotomous outcomes with their 95% confidence interval (CI). We assessed the certainty of the evidence for each of the main outcomes using the GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) approach. Results We included 16 trials (14 parallel RCTs and two cross-over trials) involving a total of 1,446 patients. Among included studies, 13 trials compared spironolactone to placebo or standard care and one trial compared eplerenone to a placebo. Most studies had an unclear or high risk of bias. Compared to control, aldosterone antagonists reduced the risk of all-cause death for patients with CKD requiring dialysis (9 trials, 1,119 patients: RR 0.45, 95% CI 0.30 to 0.67; moderate certainty of evidence). Aldosterone antagonist also decreased the risk of death due to cardiovascular disease (6 trials, 908 patients: RR 0.37, 95% CI 0.22 to 0.64; moderate certainty of evidence) and cardiovascular and cerebrovascular morbidity (3 trials, 328 patients: RR 0.38, 95% CI 0.18 to 0.76; moderate certainty of evidence). While aldosterone antagonists had an apparent increased risk of gynaecomastia compared with control (4 trials, 768 patients: RR 5.95, 95% CI 1.93 to 18.3; moderate certainty of evidence), the elevated risk of hyperkalaemia due to aldosterone antagonists was uncertain (9 trials, 981 patients: RR 1.41, 95% CI 0.72 to 2.78; low certainty of evidence). Conclusion Based on moderate certainty of the evidence, aldosterone antagonists could reduce the risk of all-cause and cardiovascular death and morbidity due to cardiovascular and cerebrovascular disease but increase the risk of gynaecomastia in patients with CKD requiring dialysis.

Background: Recent findings suggest that mild chronic kidney disease (CKD) might be associated with increased risk of venous thromboembolism (VTE). However, results were partially inconsistent, which may be due to lack of power. We therefore performed a meta-analysis to investigate the association between mild CKD and VTE incidence. Methods: A literature search was performed to retrieve community-based cohorts with information on the association of estimated glomerular filtration rate (eGFR) and albuminuria with VTE. Five cohorts were identified that were pooled on individual level. To obtain pooled hazard ratios (HRs) for VTE, linear spline models were fitted using Cox regression with shared-frailty. Models were adjusted for age, sex, hypertension, total cholesterol, smoking, diabetes, history of cardiovascular disease and body-mass index. Random-effect meta-analysis was used to obtain adjusted pooled HRs of VTE with CKD versus no CKD. Results: The analysis included 95,154 participants with 1,178 VTE cases and 599,453 person-years of follow-up. Risk of VTE increased continuously with lower eGFR and higher ACR (Figure). Compared with eGFR 100 mL/min/1.73m², pooled adjusted HRs for VTE were 1.3 (1.0–1.7) for eGFR 60, 1.8 (1.3–2.6) for 45 and 1.9 (1.2–2.9) for 30 mL/min/1.73m². Compared with albumin-creatinine ratio (ACR) 5 mg/g, pooled adjusted HRs for VTE were 1.3 (1.04–1.7) for ACR 30, 1.6 (1.1–2.4) for 300 and 1.9 (1.2–3.1) for 1000 mg/g. There was no evidence for interaction between eGFR and ACR (P=0.22). The pooled adjusted HR for CKD (eGFR <60 ml/min/1.73m² or albuminuria ≥30 mg/g) vs. no CKD was 1.5 (95%CI, 1.2–2.1). Results were similar for idiopathic and provoked VTE. Conclusion: Both reduced eGFR and elevated albuminuria are novel independent predictors of VTE in the general population.

Abstract Background Cardiovascular disease is an important driver of the increased mortality associated with chronic kidney disease (CKD). Higher left ventricular mass (LVM) predicts increased risk of adverse cardiovascular outcomes and total mortality, but previous reviews have shown no clear association between intervention-induced LVM change and all-cause or cardiovascular mortality in CKD. Methods The primary objective of this meta-analysis was to investigate whether treatment-induced reductions in LVM over periods ≥ 12 months were associated with all-cause mortality in patients with CKD. Cardiovascular mortality was investigated as a secondary outcome. Measures of association in the form of relative risks (RRs) with associated variability and precision (95% confidence intervals [CIs]) were extracted directly from each study, when reported, or were calculated based on the published data, if possible, and pooled RR estimates were determined. Results The meta-analysis included 38 trials with duration ≥ 12 months: 6 of erythropoietin stimulating agents treating to higher vs. lower hemoglobin targets, 10 of renin-angiotensin-aldosterone system inhibitors vs. placebo or another blood pressure lowering agent, 14 of modified hemodialysis regimens, and 8 of other types of interventions. All-cause mortality was reported in 116/2385 (4.86%) subjects in intervention groups and 161/2404 (6.70%) subjects in control groups. The pooled RR estimate of the 24 trials ≥ 12 months with ≥ 1 event in ≥ 1 group was 0.72 (95% CI 0.57 to 0.91, p = 0.005), with little heterogeneity across studies. Directionalities of the associations in intervention subgroups were the same. Sensitivity analyses of ≥ 6 months (31 trials), ≥ 9 months (26 trials), and > 12 months (9 trials), and including studies with no events in either group, demonstrated similar risk reductions to the primary analysis. The point estimate for cardiovascular mortality was similar to all-cause mortality, but not statistically significant: RR 0.66, 95% CI 0.38 to 1.15. Conclusions These results suggest that LVM regression may be a useful surrogate marker for benefits of interventions intended to reduce mortality risk in patients with CKD.

BackgroundSocioeconomic status (SES) has long been conjectured to be associated with the incidence and progression of chronic kidney disease (CKD), but few studies have examined this quantitatively. This meta-analysis aims to fill this gap.MethodsA systematic literature review was performed using Medline and EMBASE to identify observational studies on associations between SES and incidence and progression of CKD, published between 1974 and March 2017. Individual results were meta-analysed using a random effects model, in line with Meta-analysis of Observational Studies in Epidemiology guidelines.ResultsIn total, 43 articles met our inclusion criteria. CKD prevalence was associated with several indicators of SES, particularly lower income (OR 1.34, 95% CI (1.18 to 1.53), P<0.001; I2=73.0%, P=0.05); lower education (OR 1.21, 95% CI (1.11 to 1.32), P<0.001; I2=45.20%, P=0.034); and lower combined SES (OR 2.18, 95% CI (1.64 to 2.89), P<0.001; I2=0.0%, P=0.326). Lower levels of income, occupation and combined SES were also significantly associated with progression to end-stage renal disease (risk ratio (RR) 1.24, 95% CI (1.12 to 1.37), P<0.001; I2=66.6%, P=0.006; RR 1.05, 95% CI (1.01 to 1.09), P=0.012; I2=0.0%, P=0.796; and RR 1.39, 95% CI (1.09 to 1.79), P=0.009; I2=74.2%, P=0.009). Subgroup analyses generally confirmed these results, except in a few cases, such as an inverse association related to particular socioeconomic backgrounds and where results were adjusted by more disease-related risk factors.ConclusionLower income was most closely associated with prevalence and progression of CKD, and lower education was significantly associated with its prevalence. Evidence for other indicators was inconclusive.

Background. Carnosinase-1 (CN-1) can be detected in 24 h urine of healthy individuals and patients with type 2 diabetes (T2DM). We aimed to assess whether urinary CN-1 is also reliably measured in spot urine and investigated its association with renal function and the albumin/creatinine ratio (ACR). We also assessed associations between the CNDP1 (CTG)n genotype and CN-1 concentrations in serum and urine. Methods. Patients with T2DM (n=85) and nondiabetic patients with chronic kidney disease (CKD) (n=26) stratified by albuminuria (ACR≤300 mg/g or ACR>300 mg/g) recruited from the nephrology clinic and healthy subjects (n=24) were studied. Results. Urinary CN-1 was more frequently detected and displayed higher concentrations in patients with ACR>300 mg/g as compared to those with ACR≤300 mg/g irrespective of the baseline disease (T2DM: 554 ng/ml [IQR 212-934 ng/ml] vs. 31 ng/ml [IQR 31-63 ng/ml] (p<0.0001) and nondiabetic CKD: 197 ng/ml [IQR 112-739] vs. 31 ng/ml [IQR 31-226 ng/ml] (p=0.015)). A positive correlation between urinary CN-1 and ACR was found (r=0.68, p<0.0001). Multivariate linear regression analysis revealed that ACR and serum CN-1 concentrations but not eGFR or the CNDP1 genotype are independent predictors of urinary CN-1, explaining 47% of variation of urinary CN-1 concentrations (R2=0.47, p<0.0001). Conclusion. These results confirm and extend previous findings on urinary CN-1 concentrations, suggesting that assessment of CN-1 in spot urine is as reliable as in 24 h urine and may indicate that urinary CN-1 in macroalbuminuric patients is primarily serum-derived and not locally produced.

Abstract Background Blood pressure (BP) control is critical in delaying the progression of chronic kidney disease (CKD), which otherwise results in an increased risk of cardiovascular morbidity and mortality. Angiotensin II receptor blockers (ARBs) or angiotensin-converting enzyme inhibitors, are recommended by several guidelines as first-line treatment for patients with hypertension and CKD. Purpose We reviewed and analysed the effect of ARB treatment on BP and renal outcomes (estimated glomerular filtration rate (eGFR), serum creatinine (SCr), creatinine clearance (CrCl) or proteinuria) in patients with hypertension and CKD with or without diabetes, including large clinical trials such as RENAAL and IDNT. Methods MEDLINE, EMBASE, and BIOSIS databases were searched for literature from the earliest available date to July 2017. Randomised (parallel-group) controlled trials of ≥8 weeks assessed the impact of ARBs on systolic/diastolic BP (SBP/DBP), eGFR, SCr, CrCl or proteinuria were included in the analysis. Meta-analysis (post- versus pre-treatment) and meta-regression were conducted in R-statistical software (v3.4.1) using meta- and metafor-packages. Mean difference (MD, generic inverse variance) with 95% confidence intervals (CIs) was used to pool data for an outcome in a single forest plot. The risk of bias (quality) of included studies was assessed by the six items of the Cochrane instrument. Results Of the 165 articles assessed for eligibility, 24 studies were included in the analysis (19 evaluated ARBs as monotherapy, 4 evaluated ARBs in combination with other antihypertensives and 1 evaluated ARBs both as mono- and combination therapy). Treatment with ARBs as monotherapy for ≥8 weeks to <1 year significantly reduced mean office SBP (MD, −12.60 mmHg; 95% CI, −18.53 to −6.67)/DBP (−6.52 mmHg; −11.27 to −1.77) (p<0.01). BP reduction was also significant (p<0.01) with ARB monotherapy for ≥1 year SBP (−14.84 mmHg; −17.82 to −11.85)/DBP (−10.27 mmHg; −12.26 to −8.27). ARBs also significantly reduced SBP/DBP when combined with other antihypertensive treatments for ≥8 weeks to <1 year as well as for ≥1 year (Figure). Moreover, ARBs induced significant reductions (p<0.01) in proteinuria (≥8 weeks to <1 year [MD, −0.6 g/L; 95% CI, −0.93 to −0.26; ≥1 year [−0.9 g/L; −1.22 to −0.59]), but no significant changes in eGFR, CrCl or SCr levels. The beneficial effect of ARBs was maintained overtime with no significant additional impact on SBP change (estimate: 0.025; 95% CI, –0.14 to 0.19) or eGFR (estimate: 0.068; 95% CI, −0.14 to 0.28; p=0.53). The overall risk of bias was judged to be low. Effect of ARBs on blood pressure changes Conclusion Treatment with ARBs effectively and sustainably lowered BP and proteinuria with no significant change in eGFR in patients with hypertension and CKD with or without diabetes.
