BACKGROUND AND OBJECTIVES: The natural history of kidney disease among blacks who carry the APOL1 high-risk variants varies, with only a subgroup progressing to ESRD. We aimed to determine whether the APOL1 risk variants are associated with incident proteinuria in the context of hypertension-attributed CKD, and whether subsequent kidney function decline after the onset of proteinuria differs by APOL1 risk status. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Using Cox models, we studied the association between APOL1 risk status and incident proteinuria (defined as a doubling of urine protein-to-creatinine ratio to a level ≥0...

BACKGROUND/AIMS: To investigate the impact of kidney function (using estimated glomerular filtration rate, [eGFR]) on blood pressure variability (BPV) via a retrospective post hoc analysis of patients with hypertension enrolled in two large clinical trials. METHODS: Subject-level data were extracted from ASCOT (N=18,852) and ALLHAT (N=26,441) databases; both were randomized, active controlled studies, with treatment duration for hypertension ≥4 years. Visit-to-visit BPV was assessed using the square root of the coefficient of variation of systolic blood pressure (SBP) across visits from 12 weeks onwards...

Kidney function decreases with age; however, the long-term influence on bone density (BMD) in older women already at risk of osteoporosis is unknown. We followed kidney function and bone loss for 10 years. Declining kidney function was adversely associated with bone loss and mineral homeostasis in old women, though it attenuated with advanced aging. INTRODUCTION: Existing studies do not fully address the relationship between kidney function and bone metabolism with advanced aging in Caucasian women...

AIMS: The pathogenesis of diabetic kidney disease (DKD) is complex and multifactorial; increasing evidence suggests that tubular injury and inflammatory process are involved in disease progression. We investigated the potential association of renal expression of tubular injury markers, neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), and inflammatory markers, tumor necrosis factor receptor (TNFR) 1 and 2 with renal progression in pathologically proven diabetic nephropathy (DN)...

AIM: It is important to know which factors predict the development of microalbuminuria in patients with diabetes mellitus type II. MATERIAL: Data from the Randomized Olmesartan and Diabetes Microalbuminuria Prevention Study were used to identify predictors for the new onset of microalbuminuria. Furthermore, the interaction of baseline albuminuria and baseline estimated glomerular filtration rate (eGFR) and the effects of treatment with olmesartan were investigated...

BACKGROUND: Hyperuricemia is associated with the progression of chronic kidney disease (CKD), but it is not known whether the relationship is causal. We examined the association of hyperuricemia and uric acid lowering therapy (UALT) with progression of CKD in patients with CKD 3 and 4 in the Cleveland Clinic CKD registry. METHODS: We included 1,676 patients with CKD stages 3 and 4 from Ohio, who had measured their uric acid (UA) levels a year prior to the recording of the second eGFR <60 mL/min/1...

Background: The PROPKD score has been proposed to stratify the risk of progression to end-stage renal disease in autosomal dominant polycystic kidney disease (ADPKD) subjects. We aimed to assess its prognostic value in a genotyped subgroup of subjects from the Tolvaptan Phase 3 Efficacy and Safety Study in Autosomal Dominant Polycystic Kidney Disease (TEMPO3/4) trial. Methods: In the post hoc analysis, PKD1 and PKD2 were screened in 770 subjects and the PROPKD score was calculated in mutation-positive subjects (male: 1 point; hypertension <35 years: 2 points; first urologic event <35 years: 2 points; nontruncating PKD1 mutation: 2 points; truncating PKD1 mutation: 4 points)...

Background: Previous studies in HIV-infected individuals have demonstrated serum albumin to be strongly associated with kidney function decline, independent of urine albumin and inflammatory markers. Lower serum albumin concentrations may be an under-appreciated risk factor for kidney function decline in elders. Methods: We performed a cohort analysis in the Health Aging and Body Composition Study, a cohort of well-functioning, bi-racial, community-dwelling elders between the age of 70 and 79 years...

INTRODUCTION: Chronic kidney disease (CKD) is becoming increasingly common, especially in the elderly. In the UK, there has been a marked increase in the awareness and detection of CKD over the last decade. This is largely attributable to the introduction of automated estimated glomerular filtration rate (eGFR) reporting and renal indicators in the primary care Quality and Outcomes Framework (QOF) initiative, both of which were introduced in 2006. These two initiatives have had a significant impact on referral patterns to renal services...

BACKGROUND: Cardiovascular complications associated with expensive noninsulin agents for type 2 diabetes are the focus of concern in light of the risk of kidney dysfunction with aging. Head-to-head comparisons are unavailable to guide the choice of new drugs for hyperglycemia in patients with type 2 diabetes, decreased estimated glomerular filtration rate (eGFR) and increased cardiovascular risk. A first approach would be to document current medication choices. METHODS: All prescriptions for 10 151 patients (5623 males/4528 females) with both type 2 diabetes and hypertension seen two or  more times during a 5-year period (2007-12) at Joslin Diabetes Center were evaluated...

Chronic kidney disease (CKD) has diverse phenotypic manifestations including structural (such as fibrosis) and functional (such as glomerular filtration rate and albuminuria) alterations. Gene expression profiling has recently gained popularity as an important new tool for precision medicine approaches. Here we used unbiased and directed approaches to understand how gene expression captures different CKD manifestations in patients with diabetic and hypertensive CKD. Transcriptome data from ninety-five microdissected human kidney samples with a range of demographics, functional and structural changes were used for the primary analysis...

BACKGROUND: Although the indications for endovascular aneurysm repair for abdominal aortic aneurysm have been expanding, our primary strategy for pararenal and juxtarenal abdominal aortic aneurysm (P/JRAA) is open surgery (OS). One consequence of OS for P/JRAA is transient renal ischemia owing to renal artery clamping, which can be followed by acute kidney injury (AKI). Prior studies referred to the impact of renal ischemia on AKI, but they have rarely evaluated longer-term renal function...

There are no approved treatments for chronic antibody mediated rejection (ABMR). We conducted a multicenter, prospective, randomized, placebo-controlled, double blind clinical trial to evaluate efficacy and safety of intravenous immunoglobulins (IVIG) combined with rituximab (RTX) (EudraCT 2010-023746-67). Patients with transplant glomerulopathy and anti-HLA donor-specific antibodies (DSA) were eligible. Patients with estimated glomerular filtration rate (eGFR) < 20 mL/min/1.73m(2) and/or severe interstitial fibrosis/tubular atrophy were excluded...

BACKGROUND: In the last decade, despite constant investigation, no current single treatment has been able to decrease the incidence of diabetic nephropathy and to significantly reduce progression of diabetic CKD. METHODS: Patients with type 2 diabetes mellitus and proteinuria (>0.5 g/day) after a screening and treatment optimization phase were randomly assigned to receive silymarin or placebo. The primary outcome was a composite outcome: mortality, decline of eGFR > 50% and renal replacement therapy...

BACKGROUND: Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) significantly improve the survival of advanced lung adenocarcinoma patients harboring EGFR mutation. Limited to the standards of tumor tissue samples and detection methods, still some people can't receive target therapy following genetic guidance. This study was to explore the relevance between serum tumor markers and treatment of EGFR-TKIs. METHODS: We retrospectively collected the clinical information of advanced lung adenocarcinoma patients harboring EGFR mutation, who received EGFR-TKIs as first-line therapy from June 2009 to June 2014 in Peking University Cancer Hospital, analyzed the relationship between serum tumor markers and efficacy of EGFR-TKIs...

Background: Human immunodeficiency virus (HIV)-infected individuals are at increased risk of chronic kidney disease (CKD). Human immunodeficiency virus infection, traditional CKD risk factors, and combination antiretroviral therapy (cART) may all contribute. Methods: We compared prevalence of renal impairment (estimated glomerular filtration rate [eGFR] <60 mL/min/1.73m2), albuminuria (albumin/creatinine ratio ≥3 mg/mmol), and proximal renal tubular dysfunction (retinol-binding protein/creatinine ratio >2...
