  • Impact of Sleep Duration on Mortality and Quality of Life in Chronic
           Kidney Disease: Results from the 2007–2015 KNHANES
    • Abstract: Introduction: In the general population, short and long sleep durations have been associated with adverse health outcomes. However, this association remains unclear in patients with chronic kidney disease (CKD). We examined the relationship of sleep duration to mortality and health-related quality of life (HRQOL) in individuals with CKD. Methods: A total of 1,783 adults with CKD who participated in the 2007–2015 Korea National Health and Nutrition Examination Survey were analyzed. CKD was defined as an estimated glomerular filtration rate of #x3c;60 mL/min per 1.73 m2. Participants were categorized into 3 groups according to self-reported sleep duration: #x3c;6 h (short sleepers), 6–8 h, and #x3e;8 h (long sleepers). The outcome variables were all-cause mortality and HRQOL. HRQOL was assessed using the European Quality of Life-5 Dimensions (EQ-5D) index. Results: During a median of 6.4 years, 481 (27%) deaths occurred. In unadjusted Cox regression analysis, long sleepers with CKD had an increased risk of death (hazard ratio [HR], 1.62; 95% confidence interval [CI]: 1.26–2.09). This significant association remained after adjusting for age, sex, and BMI (HR, 1.36; 95% CI: 1.05–1.75); however, it was lost after adjusting for CKD stage, social and lifestyle factors, and presence of comorbidities (HR, 1.15; 95% CI: 0.89–1.49). Compared with 6- to 8-h sleepers with CKD, long sleepers with CKD had significantly worse HRQOL in multivariable linear regression models. The adjusted means of the EQ-5D index were 0.80 (95% CI: 0.77–0.82) for short sleepers, 0.81 (95% CI: 0.80–0.82) for 6- to 8-h sleepers, and 0.76 (95% CI: 0.73–0.79) for long sleepers (p = 0.01). Discussion/Conclusion: Long sleep duration is associated with poor HRQOL in Korean adults with CKD. The weak association between long sleep duration and mortality was attenuated after multivariable adjustment in this study.

  • The Effect of Amiloride on Proteinuria in Patients with Proteinuric Kidney
    • Abstract: Introduction: Proteinuric kidney diseases share an aggressive clinical course of developing end-stage renal disease. However, the treatment is limited. Amiloride, an epithelial sodium channel (ENaC) inhibitor, was reported to reduce proteinuria in animal studies and case reports independent of ENaC inhibition. We hypothesized that amiloride not triamterene (an analog of amiloride) would reduce proteinuria in the patients with proteinuric kidney disease. Methods: Patients with proteinuria #x3e;1.0 g/day and estimated glomerular filtration rate (eGFR) #x3e;30 mL/min/1.73 m2 on a maximum tolerable dose of angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers were randomized to receive amiloride 5 mg twice daily or triamterene 50 mg twice daily for 8 weeks, followed by 4 weeks of washout, and then crossed over to the other drug for 8 weeks. The primary outcome was 24-h urine protein reduction. Secondary outcomes were changes in body weight, blood pressure (BP), serum potassium, and eGFR. Data were analyzed by analysis of variance. Results: A total of 12 patients completed the study. Amiloride reduced 24-h urine protein by 38.7% (p = 0.002) and decreased systolic BP by 12.3 mm Hg (p = 0.04). Interestingly, triamterene reduced 24 h urine protein as well, by 32.8% (p = 0.02). Triamterene lowered eGFR by 9.0 mL/min/1.73 m2 (p = 0.007), but it was reversible. The average weight change was insignificant in both groups (p = 0.40 and 0.34 respectively). Three patients withdrew the study due to hyperkalemia. Conclusions: Both amiloride and triamterene significantly reduced proteinuria in patients with proteinuric kidney disease. The anti-proteinuric effect was additive to renin-angiotensin-aldosterone system (RAAS) blockade, given all patients were on RAAS blockade. Hyperkalemia was a safety concern. Larger trials might be needed to examine the antiproteinuric effects of ENaC inhibitors.

  • Comparison of Pre-Amputation Evaluation in Patients with and without
           Chronic Kidney Disease
    • Abstract: Introduction: Patients with chronic kidney disease (CKD) and peripheral artery disease (PAD) are more likely to undergo lower extremity amputation than patients with preserved kidney function. We sought to determine whether patients with CKD were less likely to receive pre-amputation care in the 1-year prior to lower extremity amputation compared to patients without CKD. Methods: We conducted a retrospective observational study of patients with PAD-related lower extremity amputation between January 2014 and December 2017 using a large commercial insurance database. The primary exposure was CKD identified using billing codes and laboratory values. The primary outcomes were receipt of pre-amputation care, defined as diagnostic evaluation (ankle-brachial index, duplex ultrasound, and computed tomographic angiography), specialty care (vascular surgery, cardiology, orthopedic surgery, and podiatry), and lower extremity revascularization in the 1-year prior to amputation. We conducted separate logistic regression models to estimate the adjusted odds ratio (aOR) and 95% confidence intervals (CIs) among patients with and without CKD. We assessed for effect modification by age, sex, Black race, and diabetes status. Results: We identified 8,554 patients with PAD-related amputation. In fully adjusted models, patients with CKD were more likely to receive diagnostic evaluation (aOR 1.30; 95% CI 1.17–1.44) and specialty care (aOR 1.45, 95% CI 1.27–1.64) in the 1-year prior to amputation. There was no difference in odds of revascularization by CKD status (aOR 1.03, 0.90–1.19). Age, sex, Black race, and diabetes status did not modify these associations. Discussion/Conclusion: Patients with CKD had higher odds of receiving diagnostic testing and specialty care and similar odds of lower extremity revascularization in the 1-year prior to amputation than patients without CKD. Disparities in access to pre-amputation care do not appear to explain the higher amputation rates seen among patients with CKD.

  • Specific Electrocardiograph Intervals Predict Hospitalization with Atrial
           Fibrillation in Those with Chronic Kidney Disease
    • Abstract: Introduction: Atrial fibrillation (AF) is common in patients with chronic kidney disease (CKD) and is associated with higher rates of hospitalization compared to those without AF. Whether routine electrocardiographic parameters are predictive of future hospitalizations with AF is not clear. Methods: The present study is an analysis of a prospective cohort of 2,759 patients without baseline AF from the Chronic Renal Insufficiency Cohort, a large prospective multicenter study of patients with nondialysis-dependent CKD. Unadjusted and adjusted Cox regression models were fit to examine the association of baseline categories of QTc, QRS, and PR intervals with time to first hospitalization with AF. Restricted cubic splines were used to display nonlinear associ­ations. Results: The mean age of subjects at baseline was 58 ± 11 years, 55% were male, and 44% were Black. The mean follow-up was 6.6 years during which 224 participants experienced a hospitalization with AF. The association of baseline QTc interval with risk of AF hospitalization was nonlinear, such that the lowest and highest quartiles of QTc (#x3c;407 and #x3e;431 ms, respectively) had higher adjusted risk of AF hospitalization, compared with the second quartile (407–416 ms) (aHR Q1:Q2 1.58, 95% CI 1.03–2.41; p = 0.03; aHR Q4:Q2 1.84, 95% CI 1.22–2.78; p #x3c; 0.01). Longer QRS was associated with a higher risk of hospitalization with AF among the subgroup of patients with a history of heart failure (HF). PR interval was not associated with AF hospitalization. Discussion/Conclusion: The association of QTc with risk for hospitalization with AF among patients with CKD is nonlinear, while the association of longer QRS with AF hospitalization is restricted to patients with baseline HF. Electrocardiography may represent a simple and widely accessible method for risk stratification of future AF in patients with CKD.

  • Epidemiology and Outcomes of Acute Kidney Diseases: A Comparative Analysis
    • Abstract: Introduction: Acute kidney diseases and disorders (AKD) encompass acute kidney injury (AKI) and subacute or persistent alterations in kidney function that occur after an initiating event. Unlike AKI, accurate estimates of the incidence and prognosis of AKD are not available and its clinical significance is uncertain. Methods: We studied the epidemiology and long-term outcome of AKD (as defined by the KDIGO criteria), with or without AKI, in a retrospective cohort of adults hospitalized at a single centre for #x3e;24 h between 2012 and 2016 who had a baseline eGFR ≥60 mL/min/1.73 m2 and were alive at 30 days. In patients for whom follow-up data were available, the risks of major adverse kidney events (MAKEs), CKD, kidney failure, and death were examined by Cox and competing risk regression analyses. Results: Among 62,977 patients, 906 (1%) had AKD with AKI and 485 (1%) had AKD without AKI. Follow-up data were available for 36,118 patients. In this cohort, compared to no kidney disease, AKD with AKI was associated with a higher risk of MAKEs (40.25 per 100 person-years; hazard ratio [HR] 2.51, 95% confidence interval [CI] 2.16–2.91), CKD (27.84 per 100 person-years); subhazard ratio [SHR] 3.18, 95% CI 2.60–3.89), kidney failure (0.56 per 100 person-years; SHR 24.84, 95% CI 5.93–104.03), and death (14.86 per 100 person-years; HR 1.52, 95% CI 1.20–1.92). Patients who had AKD without AKI also had a higher risk of MAKEs (36.21 per 100 person-years; HR 2.26, 95% CI 1.89–2.70), CKD (22.94 per 100 person-years; SHR 2.69, 95% CI 2.11–3.43), kidney failure (0.28 per 100 person-years; SHR 12.63, 95% CI 1.48–107.64), and death (14.86 per 100 person-years; HR 1.57, 95% CI 1.19–2.07). MAKEs after AKD were driven by CKD, especially in the first 3 months. Conclusions: These findings establish the burden and poor prognosis of AKD and support prioritisation of clinical initiatives and research strategies to mitigate such risk.

  • Trends in Peritoneal Dialysis Technique Survival, Death, and Transfer to
           Hemodialysis: A Decade of Data from the RDPLF
    • Abstract: Introduction: There is limited information on the trends of peritoneal dialysis (PD) technique survival over time. This study aimed to estimate the effect of calendar time on technique survival, transfer to hemodialysis (HD) (and the individual causes of transfer), and patient survival. Methods: This retrospective, multicenter study, based on data from the French Language Peritoneal Dialysis Registry, analyzed 14,673 patients who initiated PD in France between January 1, 2005, and December 31, 2016. Adjusted Cox regressions with robust variance were used to examine the probability of a composite end point of either death or transfer to HD, death, and transfer to HD, accounting for the nonlinear impact of PD start time. Results: There were 10,201 (69.5%) cases of PD cessation over the study period: 5,495 (37.4%) deaths and 4,706 (32.1%) transfers to HD. The rate of PD cessation due to death or transfer to HD decreased over time (PR 0.96, 95% CI: 0.95–0.97). Compared to 2009–2010, starting PD between 2005 and 2008 or 2011 and 2016 was strongly associated with a lower rate of transfer to HD (PR 0.88, 95% CI: 0.81–0.96, and PR 0.91, 95% CI: 0.84–0.99, respectively), mostly due to a decline in the rate of infection-related transfers to HD (PR 0.96, 95% CI: 0.94–0.98). Conclusions: Rates of the composite end point of either death or transfer to HD, death, and transfer to HD have decreased in recent decades. The decline in transfers to HD rates, observed since 2011, is mainly the result of a significant decline in infection-related transfers.

  • Encapsulating Peritoneal Sclerosis and Mortality Related to Infection in
    • Abstract: Introduction: Previous studies showed that the combination of peritoneal dialysis (PD) and once-weekly hemodialysis is associated with lower all-cause and cardiovascular mortality. This study aimed to compare the incidence of encapsulating peritoneal sclerosis (EPS) and infection-related mortality among those on combination therapy and those on PD alone. Methods: This prospective study on the Japanese Renal Data Registry included patients on PD from 2010 to 2014. Subjects were followed up until the end of 2015. Exposure of interest was combination therapy compared with PD alone. Patients who transitioned to combination therapy were matched with those on PD alone by propensity scores. Outcomes were EPS and infection-related mortality. Data were analyzed using Cox regression models. Results: Among the matched cohort, 608 and 869 patients were on combination therapy and on PD alone, respectively. Dialysate-to-plasma creatinine (D/P Cr) ratio decreased over time among those on combination therapy, while the ratio increased among those on PD alone (p = 0.01 by the mixed-effects model). During a median follow-up of 2.5 years, 33 experienced EPS and 55 died of infection. Combination therapy was associated with lower infection-related mortality (HR [95% CI]: 0.52 [0.28–0.95]) but not with EPS (HR: 1.21 [0.61–2.40]). Lower mortality was not limited to intra-abdominal infection but also observed for pulmonary infection. Sensitivity analyses considering the effects of dialysis facilities yielded similar results. Conclusions: Combination therapy was associated with lower infection-related mortality. It was also associated with a decline in the D/P Cr ratio over time but not with lower incidence of EPS during the short observation period.

  • Association of Pre-ESRD Serum Bicarbonate with Post-ESRD Mortality in
           Patients with Incident ESRD
    • Abstract: Background: Serum bicarbonate or total carbon dioxide (CO2) concentrations decline as chronic kidney disease (CKD) progresses and rise after dialysis initiation. While metabolic acidosis accelerates the progression of CKD and is associated with higher mortality among patients with end stage renal disease (ESRD), there are scarce data on the association of CO2 concentrations before ESRD transition with post-ESRD mortality. Methods: A historical cohort from the Transition of Care in CKD (TC-CKD) study includes 85,505 veterans who transitioned to ESRD from October 1, 2007, through March 31, 2014. After 1,958 patients without follow-up data, 3 patients with missing date of birth, and 50,889 patients without CO2 6 months prior to ESRD transition were excluded, the study population includes 32,655 patients. Associations between CO2 concentrations averaged over the last 6 months and its rate of decline during the 12 months prior to ESRD transition and post-ESRD all-cause, cardiovascular (CV), and non-CV mortality were examined by using hierarchical adjustment with Cox regression models. Results: The cohort was on average 68 ± 11 years old and included 29% Black veterans. Baseline concentrations of CO2 were 23 ± 4 mEq/L, and median (interquartile range) change in CO2 were −1.8 [−3.4, −0.2] mEq/L/year. High (≥28 mEq/L) and low (#x3c;18 mEq/L) CO2 concentrations showed higher adjusted mortality risk while there was no clear trend in the middle range. Consistent associations were observed irrespective of sodium bicarbonate use. There was also a U-shaped association between the change in CO2 and all-cause, CV, and non-CV mortality with the lowest risk approximately at −2.0 and 0.0 mEq/L/year among sodium bicarbonate nonusers and users, respectively, and the highest mortality was among patients with decline in CO2 #x3e;4 mEq/L/year. Conclusion: Both high and low pre-ESRD CO2 levels (≥28 and #x3c;18 mEq/L) during 6 months prior to dialysis transition and rate of CO2 decline #x3e;4 mEq/L/year during 1 year before dialysis initiation were associated with greater post-ESRD all-cause, CV, and non-CV mortality. Further studies are needed to determine the optimal management of CO2 in patients with advanced CKD stages transitioning to ESRD.

    • Abstract: Introduction: Patients with carbon monoxide poisoning (COP) commonly have long-term morbidities. However, it is not known whether patients with COP exhibit an increased risk of developing chronic kidney disease (CKD) and whether hyperbaric oxygen therapy (HBOT) alters this risk. Methods: This study identified 8,618 patients who survived COP and 34,464 propensity score-matched non-COP patients from 2000 to 2013 in a nationwide administrative registry. The primary outcome was the development of CKD. The association between COP and the risk of developing CKD was estimated using a Cox proportional hazards regression model; the cumulated incidence of CKD among patients stratified by HBOT was evaluated using a Kaplan-Meier analysis. Results: After adjusting for covariates, the risk of CKD was 6.15-fold higher in COP patients than in non-COP controls. Based on the subgroup analyses, regardless of demographic characteristics, environmental factors, and comorbidities, the COP cohort exhibited an increased risk of developing CKD compared with the controls. The cumulative incidence of CKD in COP patients did not differ between the HBOT and non-HBOT groups (p = 0.188). Conclusions: COP might be an independent risk factor for developing CKD. Thus, clinicians should enhance the postdischarge follow-up of kidney function among COP patients.

  • Outcomes of Interleukin-2 Receptor Antagonist Induction Therapy in
           Standard-Risk Renal Transplant Recipients Maintained on Tacrolimus: A
           Systematic Review and Meta-Analysis
    • Abstract: Introduction: The additive benefit of interleukin-2 receptor antagonist (IL2-RA) induction in standard-risk kidney transplant recipients, while maintained on tacrolimus-based immunosuppressive therapy, is uncertain. Methods: We divided the studies included in this meta-analysis into 2 groups: group A (included studies that used same dose of tacrolimus in both arms of each study) and group B (included studies that compared patients who received induction therapy and low-dose tacrolimus vs. those who received no-induction therapy and high dose of tacrolimus). Results: In group A, 11 studies were included (n = 2,886). IL2-RA induction therapy was not associated with significant differences in comparison to no-induction therapy in terms of acute rejection rates at 6 months post-transplant (risk ratio = 1.12 and 95% confidence interval [CI] range: 0.94–1.35) or graft survival at 1 year post-transplant (risk ratio = 0.78 and 95% CI range: 0.45–1.36). In group B, 2 studies were included (n = 669). There was no difference between both arms in terms of acute rejection rates (risk ratio = 0.62, with 95% CI range: 0.33–1.14) or graft survival (risk ratio = 1 and 95% CI range: 0.57–1.74). Conclusion: IL2-RA induction therapy does not improve outcomes in patients maintained on tacrolimus-based immunotherapy in standard-risk population.
