Background Intravenous sodium bicarbonate and oral acetylcysteine are widely used to prevent acute kidney injury and associated adverse outcomes after angiography without definitive evidence of their efficacy. Methods Using a 2-by-2 factorial design, we randomly assigned 5177 patients at high risk for renal complications who were scheduled for angiography to receive intravenous 1.26% sodium bicarbonate or intravenous 0.9% sodium chloride and 5 days of oral acetylcysteine or oral placebo; of these patients, 4993 were included in the modified intention-to-treat analysis...

Kidney biopsies to elucidate the cause of chronic kidney disease (CKD) are performed in a minority of persons with CKD living in high-income countries, since associated conditions-that is, diabetes mellitus, vascular disease or obesity with pre-diabetes, prehypertension or dyslipidaemia-can inform management targeted at slowing CKD progression in a majority. However, attributes of CKD may differ substantially among persons living in low-income and middle-income countries (LMICs). We used data from population or community-based studies from five LMICs (China, urban India, Moldova, Nepal and Nigeria) to determine what proportion of persons with CKD living in diverse regions fit one of the three major clinical profiles, with data from the US National Health Nutrition and Examination Survey as reference...

AKI after cardiac surgery remains strongly associated with mortality and lacks effective treatment or prevention. Preclinical studies suggest that cell-based interventions may influence functional recovery. We conducted a phase 2, randomized, double-blind, placebo-controlled trial in 27 centers across North America to determine the safety and efficacy of allogeneic human mesenchymal stem cells (MSCs) in reducing the time to recovery from AKI after cardiac surgery. We randomized 156 adult subjects undergoing cardiac surgery with evidence of early AKI to receive intra-aortic MSCs (AC607; n=67) or placebo (n=68)...

Background -In individuals with a low diastolic blood pressure (DBP), potential benefits or risks of intensive systolic blood pressure (SBP) lowering are unclear. Methods -The Systolic Blood Pressure Intervention Trial was a randomized, controlled trial that compared the effects of intensive (target <120 mm Hg) versus standard (target <140 mm Hg) SBP control in 9361 older adults with high blood pressure at increased risk of cardiovascular disease (CVD). The primary outcome was a composite of CVD events...

The comparative effectiveness of partial nephrectomy versus radical nephrectomy to preserve kidney function has not been well established. We determined the risk of clinically significant (stage 4 and higher) CKD after radical or partial nephrectomy among veterans treated for kidney cancer in the Veterans Health Administration (2001-2013). Among patients with preoperative eGFR≥30 ml/min per 1.73 m(2), the incidence of CKD stage 4 or higher after radical (n=9759) or partial nephrectomy (n=4370) was 7.9% overall...

BACKGROUND: The Systolic Blood Pressure Intervention Trial (SPRINT) showed that targeting a systolic blood pressure (SBP) of ≤ 120 mm Hg (intensive treatment) reduced cardiovascular disease (CVD) events compared to SBP of ≤ 140 mm Hg (standard treatment); however, it is unclear if this effect is similar in all racial/ethnic groups. METHODS: We analyzed SPRINT data within non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic subgroups to address this question...

BACKGROUND: Clinical practice guidelines recommend referral to nephrology when estimated glomerular filtration rate (eGFR) decreases to <30mL/min/1.73m(2); however, evidence for benefits of nephrology care are mixed. STUDY DESIGN: Observational cohort using landmark analysis. SETTINGS & PARTICIPANTS: A national cohort of veterans with advanced chronic kidney disease, defined as an outpatient eGFR≤30mL/min/1.73m(2) for January 1, 2010, through December 31, 2010, and a prior eGFR<60mL/min/1...

Studies of visit-to-visit office blood pressure (BP) variability (OBPV) as a predictor of cardiovascular events and death in high-risk patients treated to lower BP targets are lacking. We conducted a post hoc analysis of SPRINT (Systolic Blood Pressure Intervention Trial), a well-characterized cohort of participants randomized to intensive (<120 mm Hg) or standard (<140 mm Hg) systolic BP targets. We defined OBPV as the coefficient of variation of the systolic BP using measurements taken during the 3-,6-, 9-, and 12-month study visits...

The appropriate target for BP in patients with CKD and hypertension remains uncertain. We report prespecified subgroup analyses of outcomes in participants with baseline CKD in the Systolic Blood Pressure Intervention Trial. We randomly assigned participants to a systolic BP target of <120 mm Hg (intensive group; n=1330) or <140 mm Hg (standard group; n=1316). After a median follow-up of 3.3 years, the primary composite cardiovascular outcome occurred in 112 intensive group and 131 standard group CKD participants (hazard ratio [HR], 0...

The incidence of hip fracture in patients with end-stage renal disease (ESRD) is considerably higher than that in the general age- and sex-matched population. Although medical therapy for chronic kidney disease mineral bone disorder (CKD-MBD) has changed considerably over the last decade, rates of hip fracture in the entire ESRD population have not been well-characterized. Herein, we evaluated temporal trends in rates of hip fracture, in-hospital mortality, and costs of associated hospital stay in ESRD. We identified hospitalizations for hip fracture from 2003 to 2011 using the Nationwide Inpatient Sample, a representative national database inclusive of all ages and payers...

Samuel A Silver, Glenn M Chertow
Acute kidney injury (AKI) is an increasingly common condition associated with poor health outcomes. Combined with its rising incidence, AKI has emerged as a major public health concern with high human and financial costs. In England, the estimated inpatient costs related to AKI consume 1% of the National Health Service budget. In the United States, AKI is associated with an increase in hospitalization costs that range from $5.4 to $24.0 billion. The most expensive patients are those with AKI of sufficient severity to require dialysis, where cost increases relative to patients without AKI range from $11,016 to $42,077 per hospitalization...

Many patients become frail with diminished cardiorespiratory fitness while awaiting kidney transplantation. Frailty and poor fitness powerfully predict mortality, transplant graft survival, and healthcare utilization after kidney transplantation. Efforts to intervene with post-transplant physical therapy have been met with limited success, in large part due to high study dropout. We reviewed the literature on chronic kidney disease and exercise to propose a clinical framework for physical therapy interventions to improve fitness, scheduled for before the transplant...

BACKGROUND: Patients with atrial fibrillation who receive dialysis are at a high risk of ischemic stroke. The role of warfarin in mitigating this risk in patients with atrial fibrillation who receive dialysis is uncertain. Our objective was to examine the safety and efficacy of warfarin in patients who have atrial fibrillation and receive dialysis. METHODS: We used MedLine, Embase, and the Cochrane Library to conduct a systematic review and meta-analysis of published and unpublished observational and interventional studies related to the use of warfarin in patients with atrial fibrillation who receive dialysis, and provided data on the risk of stroke and/or bleeding outcomes relative to placebo or no anticoagulation therapy...

The ESRD Prospective Payment System introduced two incentives to increase home dialysis use: bundling injectable medications into a single payment for treatment and paying for home dialysis training. We evaluated the effects of the ESRD Prospective Payment System on home dialysis use by patients starting dialysis in the United States from January 1, 2006 to August 31, 2013. We analyzed data on dialysis modality, insurance type, and comorbidities from the United States Renal Data System. We estimated the effect of the policy on home dialysis use with multivariable logistic regression and compared the effect on Medicare Parts A/B beneficiaries with the effect on patients with other types of insurance...
