Author(s): Ko, Gang Jee; Rhee, Connie M; Obi, Yoshitsugu; Chang, Tae Ik; Soohoo, Melissa; Kim, Tae Woo; Kovesdy, Csaba P; Streja, Elani; Kalantar-Zadeh, Kamyar | Abstract: Arteriovenous fistulas (AVFs) are the preferred vascular access type in most hemodialysis patients. However, the optimal vascular access type in octogenarians and older (≥80 years) hemodialysis patients remains widely debated given their limited life expectancy and lower AVF maturation rates.Among incident hemodialysis patient...

Abstract Objectives Among kidney disease patients ≥80 years progressing to end-stage renal disease, there is growing interest in conservative nondialytic management approaches. However, among those who have initiated hemodialysis, little is known about the impact of withdrawal from dialysis on mortality, nor the patient characteristics associated with withdrawal from dialysis. Study design Historical cohort study. Setting and participants We examined 133,162 incident hemodialysis patients receiv...

Background There is accumulating evidence that serum levels of non–high‐density lipoprotein cholesterol (non–HDL‐C) are a more accurate predictor of cardiovascular outcomes when compared with low‐d...

Background Elevated serum high-density lipoprotein cholesterol (HDL-C) has not been associated with better cardiovascular (CV) and all-cause mortality in hemodialysis patients. However, the association between change in HDL over time and mortality has not been fully examined. Objective In a nationally representative cohort of incident hemodialysis patients who had available HDL data at baseline and 6 months after dialysis initiation, we studied the association of change in HDL-C during the first...

Background/Aims: Ultrafiltration rate (UFR) appears to be associated with mortality in prevalent hemodialysis (HD) patients. However, the association of UFR with mortality in incident HD patients remains unknown. Methods: We examined a US cohort of 110,880 patients who initiated HD from 2007 to 2011. Baseline UFR was divided into 5 groups (<4, 4 to <6, 6 to <8, 8 to <10, and ≥10 mL/h/kg body weight [BW]). We examined predictors of higher baseline UFR using logistic regression and the association...

Author(s): Ko, Gang Jee; Obi, Yoshitsugu; Soohoo, Melissa; Chang, Tae Ik; Choi, Soo Jeong; Kovesdy, Csaba P; Streja, Elani; Rhee, Connie M; Kalantar-Zadeh, Kamyar | Abstract: BACKGROUND:The population of elderly end-stage renal disease patients initiating dialysis is rapidly growing. Although longer treatment is supposed to benefit for hemodialysis (HD) patients through more solute clearance and slower fluid removal, it is not yet clear how treatment session length affects mortality risk in octo...

Background and objectives Elevated serum triglyceride/HDL cholesterol (TG/HDL-C) ratio has been identified as a risk factor for cardiovascular (CV) disease and mortality in the general population. However, the association of this important clinical index with mortality has not been fully evaluated in patients with ESRD on maintenance hemodialysis (MHD). We hypothesized that the association of serum TG/HDL-C ratio with all-cause and CV mortality in patients with ESRD on MHD is different from the ...

Purpose of review Serum high-density lipoprotein (HDL) is considered to be protective against cardiovascular disease. However, there is emerging evidence that under certain conditions the HDL molecule can become dysfunctional and proinflammatory, paradoxically leading to increased risk of cardiovascular disease. This review will provide a brief outline of the potential mechanisms by which HDL can become atherogenic and summarize some of the clinical evidence on this topic. Recent findings HDL me...

Introduction: We have previously reported that elevated serum high-density lipoprotein (HDL) cholesterol level was associated with poor cardiovascular (CV) and all-cause mortality in hemodialysis (HD) patients. However, the association between change in HDL over time and mortality in HD patients has not been fully examined. Hypothesis: We hypothesized that increasing serum HDL levels over time would not be associated with improved survival. Methods: In a national US cohort of 21,074 patients who...
