BACKGROUND Red blood cell distribution width (RDW) was recently shown to be age-dependent when using Sysmex XE-2100 hematology analyzers. As measuring RDW is subject to technology, we have investigated if this relation also exists when using a different hematology analyzer, Abbott CELL-DYN Sapphire. In addition, as RDW is generally expressed relative to mean red blood cell volume (MCV), we have...

BACKGROUND Large-scale clinical research on the relationship between red blood cell distribution width (RDW) and intermediate-term prognosis in elderly patients with coronary artery disease (CAD) is lacking. Thus, this study investigated the effects of RDW on the intermediate-term mortality of elderly patients who underwent elective percutaneous coronary intervention (PCI). METHODS Data from ...

BACKGROUND Recent studies have demonstrated that red cell distribution width (RDW) is associated with cardiovascular (CV) events and mortality. Patients with chronic kidney disease (CKD) are often anemic and have high RDW levels. In this study, we investigated the effect of RDW on major composite CV outcomes among patients with CKD. METHODS We retrospectively analyzed patients with CKD who we...

BACKGROUND Red cell distribution width (RDW) is a routine laboratory measure associated with poor outcomes in adult critical illness. OBJECTIVE We determined the utility of RDW as an early pragmatic biomarker for outcome in pediatric critical illness. METHODS We used multivariable logistic regression to test the association of RDW on the first day of pediatric intensive care unit (PICU) adm...

Red blood cell distribution width (RDW) is a robust marker of adverse clinical outcomes in various populations. However, the clinical significance of a progressive rise in RDW is undetermined in end-stage renal disease (ESRD) patients. The purpose of this study was to determine the prognostic importance of a change in RDW in ESRD patients. Three hundred twenty-six incident dialysis patients wer...

BACKGROUND Red cell distribution width (RDW), one of many routinely examined parameters, shows the heterogeneity in erythrocyte size. We investigated the association of RDW levels with clinical parameters and prognosis of lung cancer patients. METHODS Clinical and laboratory data from 332 patients with lung cancer in a single institution were retrospectively studied by univariate analysis. Ka...

To investigate the prognostic value of the red blood cell distribution width(RDW) recovery from low levels at diagnosis after completion of first line therapy in mutiple myeloma (MM)patients,we enrolled 78 consecutive patients with MM and followed up from 2005 to 2016 in our hospital. The RDW was measured following completion of first-line therapy.The log-rank test, univariate analysis, and Cox...

BACKGROUND Red blood cell distribution width (RDW) is a novel prognostic marker that reflects oxidative stress and chronic inflammation in patients with cardiovascular disease. Diabetes mellitus increases oxidative stress and vascular inflammation, which accelerate atherosclerosis. However, the relationship between RDW and long-term outcome in diabetic patients with coronary artery disease (CAD...

INTRODUCTION A potential independent association was recently demonstrated between high red blood cell distribution width (RDW) and the risk of all-cause mortality in critically ill patients, although the mechanism underlying this relationship remains unclear. Little is known about the impact changes in RDW may have on survival in critically ill patients. Therefore, we investigated the prognost...

Red blood cell distribution width (RDW) is a parameter reported in complete blood cell count tests, and has been reported as an inflammatory biomarker. Multiple myeloma (MM) is known to be associated with inflammatory microenvironments. However, the importance of RDW has been seldom studied in MM. For this study, 146 symptomatic myeloma patients with available RDW at diagnosis were retrospectiv...
