REVIEW
Paraskevi Goggolidou, Patricia D Wilson
Biomarkers, the measurable indicators of biological conditions, are fast becoming a popular approach in providing information to track disease processes that could lead to novel therapeutic interventions for chronic conditions. Inherited, chronic kidney disease affects millions of people worldwide and although pharmacological treatments exist for some conditions, there are still patients whose only option is kidney dialysis and kidney transplantation. In the past 10 years, certain chronic kidney diseases have been reclassified as ciliopathies...

Purpose: In diabetes, pancreatic beta cell mass declines significantly prior to onset of fasting hyperglycemia. This decline may be due to endoplasmic reticulum (ER) stress, and the system L amino acid transporter LAT1 may be a biomarker of this process. In this study, we used 5-(2- (18)F-fluoroethoxy)-L-tryptophan ( (18)F-L-FEHTP) to target LAT1 as a potential biomarker of beta cell function in diabetes. Procedures: Uptake of (18)F-L-FEHTP was determined in wild-type C57BL/6 mice by ex vivo biodistribution...

BACKGROUND: Adverse outcome of chronic kidney disease, such as end stage renal disease, is a significant burden on personal health and healthcare costs. Urinary tubular injury markers, such as NGAL, KIM-1 and NAG, could provide useful prognostic value for the early identification of high-risk patients. However, discrepancies between recent large prospective studies have resulted in controversy regarding the potential clinical value of these markers. Therefore, we conducted the first meta-analysis to provide a more persuasive argument to this debate...

PURPOSE OF REVIEW: Acute kidney injury (AKI) occurs in up to 30% after cardiac surgery and is associated with adverse outcome. Currently, cardiac surgery-associated acute kidney injury (CSA-AKI) is diagnosed by Kidney Disease: Improving Global Outcomes criteria based on creatinine and urine output. To detect and treat AKI earlier, various biomarkers have been evaluated. This review addresses the current position of the two damage biomarkers neutrophil gelatinase-associated lipocalin (NGAL) and [TIMP-2] [IGFBP7] in clinical practice...

AIM: Leukocyte profile has been related to clinical outcome in patients with ST-segment elevation (STE) myocardial infarction (MI). However, whether eosinophil to leukocyte ratio (ELR) predicts clinical outcome in patients who have undergone primary percutaneous coronary intervention (PCI) remains unclear. Therefore, we examined the prognostic value of ELR in this patient population. METHODS: We retrospectively analyzed the data of 331 consecutive patients who underwent primary PCI for STEMI between January 2009 and March 2015...

INTRODUCTION: Patients on long-term hemodialysis are at a higher risk of cardiovascular disease and premature mortality. It is generally believed that omega-3 supplementation can prevent cardiovascular events due to its anti-inflammatory and anti-atherosclerotic effects. MATERIALS AND METHODS: Fifty-two hemodialysis patients were divided into 2 groups to receive omega-3 and placebo for 6 six months. Serum biomarkers and inflammatory agents were measured in both groups before and after the intervention...

OBJECTIVE: The predictive value of microalbuminuria (MAU) for kidney damage is limited in type 2 diabetes (T2D). We studied whether a urine proteome specific for sight-threatening proliferative diabetic retinopathy (PDR) is an indicator to predict chronic renal insufficiency (CRI) in patients with T2D. RESEARCH DESIGN AND METHODS: A shotgun urine proteomic analysis was performed in patients with MAU and PDR (case subjects) and in patients with MAU and a duration of T2D for >10 years but with without any degree of retinopathy (control subjects)...

BACKGROUND: Blood biomarkers of neurovascular damage are used clinically to diagnose the presence severity or absence of neurological diseases, but data interpretation is confounded by a limited understanding of their dependence on variables other than the disease condition itself. These include half-life in blood, molecular weight, and marker-specific biophysical properties, as well as the effects of glomerular filtration, age, gender, and ethnicity. To study these factors, and to provide a method for markers' analyses, we developed a kinetic model that allows the integrated interpretation of these properties...

BACKGROUND: Leukocyte telomere length (LTL) is a putative biological marker of immune system age, and there are demonstrated associations between LTL and cardiovascular disease. This may be due in part to the relationship of LTL with other biomarkers associated with cardiovascular disease risk. However, the strength of associations between LTL and adiposity, metabolic, proinflammatory, and cardiovascular biomarkers has not been systematically evaluated in a United States nationally representative population...

PURPOSE OF REVIEW: Although uromodulin or Tamm-Horsfall protein was discovered over 60 years ago, its functional role in humans remains unclear. This review highlights new studies elucidating the clinical correlates of uromodulin, its association with kidney function decline, nephrolithiasis and urinary host defense. RECENT FINDINGS: Uromodulin is evolutionarily conserved and has multiple functional roles. In large population studies, higher levels of uromodulin are associated with higher estimated glomerular filtration rate (eGFR) and kidney size, possibly indicating greater kidney functional reserve...

BACKGROUND: Donor-specific antibody (DSA) is a widely-used biomarker for antibody-mediated rejection (ABMR) but correctly indicates only 30-40% of patients with ABMR. Additional biomarkers of ABMR in kidney transplant recipients are needed. METHODS: All 68 kidney transplanted-recipients enrolled in this study were negative for graft rejection as determined by surveillance-biopsy ELISA at day 7 post-transplantation. Allograft biopsy was then performed at 6 months post-transplantation for subclinical-ABMR detection...

Neutrophil gelatinase-associated lipocalin is an extracellular protein produced mostly in kidney. Recently, it has become a promising biomarker of renal damage in vivo. On the other hand, the validation of NGAL as a biomarker for nephrotoxicity estimation in vitro has not been characterized in detail yet. Since the HK-2 cells are frequently used human kidney cell line, we aimed to characterize the production of NGAL in these cells and to evaluate NGAL as a possible marker of cell impairment. We used heavy metals (mercury, cadmium), peroxide, drugs (acetaminophen, gentamicin) and cisplatin to mimic nephrotoxicity...

Acute kidney injury (AKI) impairs short- and long-term prognosis of affected patients even in case of apparantly mild course and 'full' recovery as measured by follow-up serum creatinine concentrations. Late or none intervention worsens prognosis. However, there are modifiable factors potentially contributing to preserved long-term renal function. Effective treatment is multifactorial and includes identification and reversal of AKI etiology and generation of a (micro)environment for optimal renal recovery. Available treatment options for AKI in perioperative and critically ill patients will be discussed in the setting of novel kidney biomarkers...
