John T Daugirdas
BACKGROUND: Changes in plasma volume during hemodialysis are complex and have been shown to depend on the rate of fluid removal and the degree of fluid overload. We examined changes in total protein concentration during and shortly after a dialysis treatment in archived data from the HEMO study. METHODS: During follow-up months 4 and 36 of the HEMO study, additional blood samples were obtained during a typical dialysis session at 30 and 60 min after dialysis. In 315 studies from 282 patients where complete data were available, we calculated the concentration change in total protein and compared it to the modeled change in both total body water and extracellular fluid space as derived from 2-pool urea kinetic modeling...

PURPOSE: Frail patients are known to experience poor outcomes. Nevertheless, we know less about how frailty manifests itself in patients' physiology during critical illness and how it affects resource use in intensive care units (ICU). We aimed to assess the association of frailty with short-term outcomes and organ support used by critically ill patients. METHODS: Retrospective analysis of prospective collected data from 93 ICUs in Brazil from 2014 to 2015. We assessed frailty using the modified frailty index (MFI)...

BACKGROUND/AIMS: Blood pressure variability (BPV) is a novel cardiovascular risk factor for the population undergoing hemodialysis (HD). METHODS: We conducted a retrospective cohort study of 526 HD patients. Four short-term peridialysis BPV metrics were analyzed: systolic blood pressure (SBP) change, SBP coefficient of variation (CV), SBP intradialytic average real variability (ARV), and absolute SBP residual. Multi variate analysis with Cox regression models were used to account for the potential confounders...

Nephrology is a complex discipline, including care of kidney disease, dialysis, and transplantation. While in Europe, about 1:10 individuals is affected by chronic kidney disease (CKD), 1:1000 lives thanks to dialysis or transplantation, whose costs are as high as 2% of all the health care budget. Nephrology has important links with surgery, bioethics, cardiovascular and internal medicine, and is, not surprisingly, in a delicate balance between specialization and comprehensiveness, development and consolidation, cost constraints, and competition with internal medicine and other specialties...

Evaluation of potential kidney transplant recipients is important to identify and treat conditions that may influence graft or patient survival after transplantation. We performed a single-center, observational cohort study to determine whether pre-transplant midodrine use influences outcomes after kidney transplantation. We analyzed graft and patient outcomes for adult patients who underwent a kidney-only transplantation at Barnes-Jewish Hospital from January 1999 to December 2015. We quantified adjusted associations of pre-transplant midodrine use with post-transplant complications by multivariable Cox regression...

BACKGROUND: Heart transplant allocation in the United States is made on the basis of coarse tiers, defined by mechanical circulatory devices and therapy for advanced heart failure, updated infrequently as a patient's condition deteriorates. Thus, many patients die awaiting heart transplantation. What is needed is a tool that continuously updates risk of mortality as a patient's condition changes to inform clinical decision making. OBJECTIVES: This study sought to develop a decision aid that aggregates adverse events and measures of end-organ function into a continuously updated waitlist mortality estimate...

BACKGROUND: Calcium gradient, the difference between serum calcium and dialysate calcium d[Ca], is the main contributor factor influencing calcium transfer during hemodialysis. The impact, however, of bone turnover, on calcium mass transfer during hemodialysis is still uncertain. METHODS: This prospective cross-sectional study included 10 patients on hemodialysis for a 57.6±16.8 months, with severe hyperparathyroidism. Patients were submitted to 3 hemodialysis sessions using d[Ca] of 1...

Direct acting antivirals approved for use in end-stage renal disease (ESRD) patients now exist. HCV-positive (HCV+) ESRD patients have the opportunity to decrease waiting times for transplantation by accepting HCV-infected kidneys. The optimal timing for HCV treatment (pre vs posttransplant) among kidney transplant candidates is unknown. Monte Carlo microsimulation of 100,000 candidates was used to examine the cost-effectiveness of HCV treatment pretransplant versus posttransplant by liver fibrosis stage and waiting time over a lifetime time horizon using two regimens approved for ESRD patients...

Patients with end-stage renal disease (ESRD) undergoing haemodialysis (HD) experience oxidative/carbonyl stress, which is postulated to increase after the HD session. The influence of diabetes mellitus and sex on oxidation of plasma proteins in ESRD has not yet been clarified despite that diabetic nephropathy is the most common cause of ESRD in developed and developing countries and despite the increasingly emerging differences between males and females in epidemiology, pathophysiology, clinical manifestations, and outcomes for several diseases...

INTRODUCTION: Haemodialysis (HD) is the cornerstone treatment for patients with end-stage renal disease (ESRD). However, highly protein bound or large molecular weight uremic toxins such as phenolic and indolic compounds and homocysteine, which are associated with adverse outcomes such as cardiovascular disease of patients with ESRD, are difficult to remove via HD but can be effectively eliminates by haemoperfusion (HP). The proposed trial (referred to as HD/HP vs HD below) is a randomised, open-label, multicentre trial comparing HD plus HP versus HD alone in adult patients with ESRD...

BACKGROUND: Vaccines prevent infections and avoid related complications. Low rates in immunocompromised patients are concerning due to increased morbidity. Vaccinations are less effective when administered post-transplant and should be administered prior. We describe pre-transplant vaccination rates among kidney or kidney-pancreas transplant recipients. METHODS: Retrospective review including adults receiving kidney or kidney-pancreas allografts at Cleveland Clinic from October 2013 to October 2016...
