Background/Aims: Ventricular arrhythmia is associated with increased risk of cardiovascular events and death in the general population. Sudden death is a leading cause of death in end-stage renal disease. We aimed at evaluating the effects of ventricular arrhythmia on clinical outcomes in patients with earlier stages of chronic kidney disease (CKD). Methods: In a prospective study of 109 nondialyzed CKD patients (estimated glomerular filtration rate 34.8 ± 16.1 ml/min/1.73 m2, 57 ± 11.4 years, 61% male, 24% diabetics), we tested the hypothesis that the presence of subclinical complex ventricular arrhythmia, assessed by 24-hour electrocardiogram, is associated with increased risks of cardiovascular events, hospitalization, and death and with their composite outcome during 24 months of follow-up. Complex ventricular arrhythmia was defined as the presence of multifocal ventricular extrasystoles, paired ventricular extrasystoles, nonsustained ventricular tachycardia, or R wave over T wave. Results: We identified complex ventricular arrhythmia in 14% of participants at baseline. During follow-up, 11 cardiovascular events, 15 hospitalizations, and 4 deaths occurred. The presence of complex ventricular arrhythmia was associated with cardiovascular events (p < 0.001), hospitalization (p = 0.018), mortality (p < 0.001), and the composite outcome (p < 0.001). In multivariate Cox regression analysis, adjusting for demographic characteristics, complex ventricular arrhythmia was associated with increased risk of the composite outcome (HR 4.40; 95% CI 1.60-12.12; p = 0.004). Conclusion: In this pilot study, the presence of asymptomatic complex ventricular arrhythmia was associated with poor clinical outcomes in nondialyzed CKD patients.

To investigate the association of body weight variability (BWV) with adverse cardiovascular (CV) outcomes in patient with pre-dialysis chronic kidney disease (CKD), a total of 1867 participants with pre-dialysis CKD from Korean Cohort Study for Outcomes in Patients With Chronic Kidney Disease (KNOW-CKD) were analyzed. BWV was defined as the average absolute difference between successive values. The primary outcome was a composite of non-fatal CV events and all-cause mortality. Secondary outcomes were fatal and non-fatal CV events and all-cause mortality. High BWV was associated with increased risk of the composite outcome (adjusted hazard ratio (HR) 1.745, 95% confidence interval (CI) 1.065 to 2.847) as well as fatal and non-fatal CV events (adjusted HR 1.845, 95% CI 1.136 to 2.996) and all-cause mortality (adjusted HR 1.861, 95% CI 1.101 to 3.145). High BWV was associated with increased risk of fatal and non-fatal CV events, even in subjects without significant body weight gain or loss during follow-up periods (adjusted HR 2.755, 95% CI 1.114 to 6.813). In conclusion, high BWV is associated with adverse CV outcomes in patients with pre-dialysis CKD.

Abstract Background and Aims Anemia is a major complication of Chronic Kidney Disease (CKD). There are few large observational studies analyzing the association between anemia and significant clinical outcomes in non-dialysis dependent CKD (ND-CKD) patients. Our aim was to evaluate the prevalence of anemia and iron deficiency and their association with mortality, cardiovascular events, need for renal replacement therapy and hospitalizations in an outpatient ND-CKD population. Method A patient-level, retrospective, cohort analysis of all adult ND-CKD patients evaluated in an outpatient nephrology clinic between January 2012 to December 2017 with at least one year follow up. Anemia (defined according to the WHO definition - Hemoglobin [Hb] &lt; 13.0 g/dL in men and 12.0g/dL in women), absolute iron deficiency (ferritin &lt; 100 ng/mL), other demographic and clinical data (CKD staging and etiology, comorbidities) were assessed at the first visit through individual consultation of electronic medical records. Results During the 6-year period, 3008 patients were identified (mean age 70.9±14.1 years; 54.5% male; 91.7% white) with a mean follow-up of 3.3±2.0 years. The most frequent cardiovascular comorbidities were arterial hypertension (81.9%), obesity (58%), diabetes mellitus (57.9%) and dyslipidemia (43.9%). The mean Hb was 11.8 ±1.9 g/dL. Anemia was present in 49.9 % of patients, with similar distribution between genders (50.4% in men vs 49.6% in women) and more frequent in white patients (92% vs 8% p= 0.019). Anemia prevalence increased across CKD stages - 12.9%, 25.9%, 57.2%, 72.7% and 86.4% for stages 1 to 5, respectively (p&lt;0,001 for the trend). Anemia was associated with cardiovascular comorbidities, such as diabetes (52% vs 32%, p&lt;0.001), hypertension (86.7% vs 77.7%, p&lt;0.001), obesity (65.5% vs 60.8 %, p=0.012) and dyslipidemia (46% vs 41.2%, p=0.01). Among patients with ferritin levels available (1638), 41.7% had absolute iron deficiency. Anemia was associated with increased mortality (74% vs 26%, p &lt;0,001) and hospitalization (61,8% vs 38.2%, p &lt;0.001). In multivariate logistic regression analysis, anemia (OR 1,923; 95%IC 1,362-2.716; p&lt;0,001) and absolute iron deficiency (OR 0.531 95% IC 0.348-0.809; p=0.003) emerged as independent predictors of death. Cardiovascular events were more prevalent in the group of patients with Hb levels 10-12 g/dL (4.1 vs2.3% 2p=0.006). Conclusion As expected, anemia prevalence increases across CKD stages and, as well as absolute iron deficiency, is independently associated with adverse clinical outcomes in ND-CKD patients, including death. Future studies should be developed to investigate if correction of these factors improves adverse outcomes.

Despite rapid progress in improving dialysis technology in recent years, mortality in hemodialysis (HD) patients remains quite high. The main reasons are cardiovascular disease. The search of factors that are associated with an increased risk of adverse clinical events in patients with chronic kidney disease (CKD) is an urgent problem of modern nephrology. Prolactin (PL) is a unique hormone that can perform the functions of both a hormone and a neuropeptide. Among patients with CKD, the frequency of hyperprolactinemia (HPL) increases with decreasing glomerular filtration rate (GFR). There is a moderate HPL due to impaired degradation of PL in the kidneys. Hemodialysis does not affect the level of PL. A negative correlation between the levels of PL and GFR, PL and albumin levels and PL and Hb levels are shown in the studies. Serum PL is positively correlated with blood pressure and the risk of cardiovascular events. Despite the relatively high prevalence of HPL in patients with CKD, particularly in the dialysis population, there is uncertainty about the consequences of this condition for this cohort of patients. Further studies are needed to study the effects of HPL on clinical outcomes in patients with CKD. If a causal relationship between HPL and clinical outcomes, in particular cardiovascular events, is shown, HPL may be a potential target for therapeutic interventions.

Abstract Background Atrial fibrillation (AF) increases the risk of death, stroke/systemic embolism and heart failure (HF). Plasma natriuretic peptide (NP) level is an important prognostic marker in HF patients. However, little is known regarding the prognostic significance of plasma NP level in AF patients without HF. Purpose The aim of this study is to investigate the relationship between plasma NP level and clinical outcomes such as all-cause death, stroke/systemic embolism and HF hospitalization during follow-up period in AF patients without HF. Methods The Fushimi AF Registry is a community-based prospective survey of AF patients in our city. The inclusion criterion of the registry is the documentation of AF at 12-lead electrocardiogram or Holter monitoring at any time, and there are no exclusion criteria. We started to enroll patients from March 2011, and follow-up data were available for 4,466 patients by the end of November 2019. From the registry, we excluded 1,220 patients without a pre-existing HF (defined as having one of the following; prior hospitalization for HF, New York Heart Association class ≥2, or left ventricular ejection fraction &lt;40%). Among 3,246 AF patients without HF, we investigated 1,189 patients with the data of plasma BNP (n=401) or N-terminal pro-BNP (n=788) level at the enrollment. We divided the patients according to the quartile of each plasma BNP or NT-pro BNP level and compared the backgrounds and outcomes between these 4 groups stratified by plasma NP level. Results Of 1,189 patients, the mean age was 72.1±10.2 years, 454 (38%) were female and 684 (58%) were paroxysmal AF. The mean CHADS2 and CHA2DS2-VASc score were 1.6±1.1 and 2.9±1.5, respectively. Oral anticoagulants were prescribed in 671 (56%) at baseline. The median (interquartile range) BNP and N-terminal pro-BNP level were 84 (38, 176) and 500 (155, 984) pg/ml, respectively. Patients with high plasma NP level were older, and demonstrated lower prevalence of paroxysmal AF, higher CHADS2 and CHA2DS2-VASc scores and higher prevalence of chronic kidney disease and oral anticoagulants prescription (all P&lt;0.01). A total of 165 all-cause death, 114 stroke/systemic embolism and 103 HF hospitalization occurred during the median follow-up period of 5.0 years. Kaplan-Meier curves demonstrated that higher plasma NP level was significantly associated with the incidences of all-cause death, stroke/systemic embolism and HF hospitalization in AF patients without HF (Figure 1A). Multivariable Cox regression analysis revealed that plasma NP level could stratify the risk of clinical outcomes even after adjustment by type of AF, CHA2DS2-VASc score, chronic kidney disease and oral anticoagulant prescription (Figure 1B). Conclusion Plasma NP level is a significant prognostic marker for all-cause death, stroke/systemic embolism and HF hospitalization in AF patients without HF, suggesting the importance of measuring plasma NP level in AF patients even without HF.

We investigated the association between dietary micronutrient intakes and the risk of chronic kidney disease (CKD) in the Ansan-Ansung study of the Korean Genome and Epidemiologic Study (KoGES), a population-based prospective cohort study. Of 9079 cohort participants with a baseline estimate glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2 and a urine albumin to creatinine ratio (UACR) <300 mg/g and who were not diagnosed with CKD, we ascertained 1392 new CKD cases over 12 year follow-up periods. The risk of CKD according to dietary micronutrient intakes was presented using hazard ratios (HRs) and 95% confidence intervals (95% CIs) in a full multivariable Cox proportional hazard models, adjusted for multiple micronutrients and important clinico-epidemiological risk factors. Low dietary intakes of phosphorus (<400 mg/day), vitamin B2 (<0.7 mg/day) and high dietary intake of vitamin B6 (≥1.6 mg/day) and C (≥100 mg/day) were associated with an increased risk of CKD stage 3B and over, compared with the intake at recommended levels (HR = 6.78 [95%CI = 2.18–21.11]; HR = 2.90 [95%CI = 1.01–8.33]; HR = 2.71 [95%CI = 1.26–5.81]; HR = 1.83 [95%CI = 1.00–3.33], respectively). In the restricted population, excluding new CKD cases defined within 2 years, an additional association with low folate levels (<100 µg/day) in higher risk of CKD stage 3B and over was observed (HR = 6.72 [95%CI = 1.40–32.16]). None of the micronutrients showed a significant association with the risk of developing CKD stage 3A. Adequate intake of micronutrients may lower the risk of CKD stage 3B and over, suggesting that dietary guidelines are needed in the general population to prevent CKD.

Obesity has become a pandemic. It is one of the strongest risk-factors of new-onset chronic kidney disease (CKD). However, the effects of obesity and abdominal obesity on the risk of developing CKD in young adults has not been elucidated. From a nationwide health screening database, we included 3,030,884 young adults aged 20–39 years without CKD during a baseline examination in 2009–2010, who could follow up during 2013–2016. Patients were stratified into five levels based on their baseline body mass index (BMI) and six levels based on their waist circumference (WC; 5-cm increments). The primary outcome was the development of CKD. During the follow up, until 2016, 5853 (0.19%) participants developed CKD. Both BMI and WC showed a U-shaped relationship with CKD risk, identifying the cut-off values as a BMI of 21 and WC of 72 cm in young adults. The obesity group (odd ratio [OR] = 1.320, 95% confidence interval [CI]: 1.247–1.397) and abdominal obesity group (male WC ≥ 90, female WC ≥ 85) (OR = 1.208, 95%CI: 1.332–1.290) showed a higher CKD risk than the non-obesity or non-abdominal obesity groups after adjusting for covariates. In the CKD risk by obesity composite, the obesity displayed by the abdominal obesity group showed the highest CKD risk (OR = 1.502, 95%CI: 1.190–1.895), especially in those under 30 years old. During subgroup analysis, the diabetes mellitus (DM) group with obesity or abdominal obesity paradoxically showed a lower CKD risk compared with the non-obesity or non-abdominal obesity group. Obesity and abdominal obesity are associated with increased risk of developing CKD in young adults but a decreased risk in young adults with diabetes.

Background: Benefits of phosphate-lowering interventions on clinical outcomes in patients with chronic kidney disease (CKD) are unclear; systematic reviews have predominantly involved dialysis patients. This study aimed to summarize evidence from randomized controlled trials (RCTs) concerning benefits and risks of non-calcium-based phosphate-lowering treatment in non-dialysis CKD. Methods: We conducted a systematic review and meta-analyses of RCTs involving noncalcium-based phosphate-lowering therapy compared to placebo, calcium-based binders, or no study medication, in adults with CKD not on dialysis or post-transplant. RCTs had ≥3 months follow up and outcomes included biomarkers of mineral metabolism, cardiovascular parameters, and adverse events. Outcomes were meta-analyzed using the Sidik-Jonkman method for random effects. Unstandardized mean differences were used as effect sizes for continuous outcomes, with common measurement units and Hedge's g standardized mean differences (SMD) otherwise. Odds ratios were used for binary outcomes. Cochrane risk of bias and GRADE assessment determined the certainty of evidence. Results: Twenty trials involving 2,498 participants (median sample size 120, median follow up 9 months) were eligible for inclusion. Overall, risk of bias was low. Compared with placebo, non calcium-based phosphate binders reduced serum phosphate (12 trials, weighted mean difference -0.37, 95% CI -0.58,-0.15 mg/dL, low certainty evidence) and urinary phosphate excretion (8 trials, SMD -0.61, 95% CI -0.90,-0.31, low certainty evidence), but resulted in increased constipation (9 trials, log odds ratio [OR] 0.93, 95% CI 0.02, 1.83, low certainty evidence) and greater vascular calcification score (3 trials, SMD 0.47, 95% CI 0.17, 0.77, very low certainty evidence). Data for effects of phosphate-lowering therapy on cardiovascular events (log OR 0.51 [95% CI -0.51, 1.17]) and death were scant. Conclusions: Non-calcium-based phosphate-lowering therapy reduced serum phosphate and urinary phosphate excretion, but there was an unclear effect on clinical outcomes and intermediate cardiovascular end-points. Adequately powered RCTs are required to evaluate benefits and risks of phosphate-lowering therapy on patient-centered outcomes.

Abstract Background and Aims Polypharmacy (PP) is common in end-stage chronic renal disease patients, largely because of the existence of multiple comorbid conditions. PP has the potential for harm and benefits, and the association between PP and mortality and morbidity in hemodialysis patients currently remains unclear. We examined the association of PP and the risk of clinical outcomes, such as all-cause mortality, all-cause hospitalization and cardiovascular events, in initial hemodialysis patients at admission and discharge. Method Study design: Cohort study. Setting: Participants: One hundred and fifty-two initial hemodialysis patients (female vs. male, 88 vs. 64; mean age, 70.3 years) were enrolled between February 2015 and March 2018 at the Nobeoka Prefectural Hospital and Chiyoda Hospital. Predictor: Patients were divided into 2 groups according to PP (6 or more drug prescriptions, or less) during admission and discharge for the initiation of hemodialysis. Outcomes: All-cause mortality, all-cause hospitalization and cardiovascular events (hospitalization due to stroke, ischemic heart disease or peripheral artery disease) during the mean 2.8-year follow-up. Measurements: Hazard ratios (HRs) were estimated using Cox’s model for the relationships between PP and the clinical outcomes, and adjusted for potential confounders, including age, sex, body mass index, systolic and diastolic blood pressure, Charlson comorbidity risk index, hemoglobin, serum levels of albumin, albumin-corrected Ca, phosphate, parathyroid hormone, C-reactive protein and NT-proBNP; and use of erythropoietin stimulating agents. The group with 5 or less drug prescriptions was set as reference. Results Among the patients in this cohort study, the number of prescribed drugs per patient averaged 7.4 at admission and 6.9 at discharge for initial hemodialysis. One hundred (65.8%) and 94 patients (61.8%) had PP at admission and discharge, respectively. During follow-up, 20 patients died, 71 patients were hospitalized and 25 patients had cardiovascular events. PP at admission is significantly associated with cardiovascular events (HR 8.50, 95%CI 1.45-49.68). Furthermore, PP at discharge is significantly associated with all-cause hospitalization and cardiovascular events (HR 1.95, 95%CI 1.01-3.70; HR 53.16, 95%CI 2.70-104.62, respectively). However, PP is not significantly associated with all-cause mortality at admission or discharge. Conclusion Among Japanese patients starting hemodialysis, PP may be associated with clinical outcomes. However, it remains unclear whether PP is the direct cause of the outcomes or is simply a marker for increased risk of outcomes.

Abstract It is well known from observational studies that sedentary lifestyle and reduced physical activity are common in dialysis and chronic kidney disease (CKD) patients and associate with an increased risk of morbidity and mortality in this patient population. Epidemiological studies indicate that CKD patients undergo physical activity ~9 days/month and 43.9% of dialysis patients report not exercising at all. On the basis of awareness about the strong link between sedentary lifestyle and adverse clinical outcomes, the National Kidney Foundation and Kidney Disease: Improving Global Outcomes have provided specific recommendations for physical activity in patients with kidney disease. Given the fact that CKD is a public health problem and it is still debated which type of exercise should be prescribed in these patients, this review focuses on the most robust evidence accumulated so far on the beneficial effect of various types of physical exercise on clinical outcomes in CKD and dialysis patients. This review does not treat this very important topic in another CKD category of patients, such as kidney-transplanted patients, for whom a special issue should be dedicated.
