Utilization of Potassium Binders for the Management of Hyperkalemia in Chronic Kidney Disease: A Position Statement by US Nephrologists.

Adv Kidney Dis Health

November 2024

Division of Nephrology, Department of Medicine, University of North Carolina Kidney Center, Chapel Hill, NC and the WG (Bill) Hefner Salisbury VA Medical Center, Salisbury, NC. Electronic address:

Two potassium (K) binders-patiromer sorbitex calcium and sodium zirconium cyclosilicate-are recommended by international guidelines for the management of hyperkalemia. There is, however, no universally accepted best practice for how to appropriately utilize K binders in the long-term clinical management of CKD. A panel of eight US-based nephrologists convened in October 2022 to develop a consensus statement regarding utilizing K binders in clinical practice to help manage patients with nonemergent, persistent/recurrent hyperkalemia in CKD.

Article Synopsis
  • Over 3.5 million people globally, including 540,000 in the US, rely on maintenance dialysis for chronic kidney failure, with a 5-year survival rate of around 40%.
  • The initiation of dialysis is guided by symptoms of uremia, volume overload, and worsening kidney function, rather than a specific eGFR threshold, emphasizing the need for patient-clinician shared decision-making.
  • Dialysis can lead to complications such as cardiovascular issues and infections, with notable rates of catheter-related bloodstream infections and peritonitis, while chronic conditions stemming from kidney failure often require additional medication management.

Complement as a major mediator of ANCA vasculitis and a target for precision therapy.

Expert Rev Clin Immunol

January 2025

Division of Rheumatology, Department of Pediatrics, University of North Carolina, Chapel Hill, NC, USA.

Introduction: Complement was long thought not to be involved in ANCA vasculitis pathogenesis until studies in murine models demonstrated its central role. The current theory is ANCA-activated neutrophils degranulate and release factors that activate complement, which, in turn, recruits more neutrophils and causes an inflammatory amplification loop that results in the vascular inflammation characteristic of disease. Targeting this amplification loop through complement inhibition has proven to be effective in ANCA vasculitis treatment.

Endothelial cells are a heterogeneous population with various organ-specific and conserved functions that are critical to organ development, function, and regeneration. Here we report a Sox17-Erg direct reprogramming approach that uses cardiac fibroblasts to create differentiated endothelial cells that demonstrate endothelial-like molecular and physiological functions in vitro and in vivo. Injection of these induced endothelial cells into myocardial infarct sites after injury results in improved vascular perfusion of the scar region.

Importance: Individuals with dialysis-dependent kidney failure have numerous risk factors for medication-related adverse events, including receipt of care by multiple clinicians and initiation of some QT-prolonging medications with known risk of torsades de pointes (TdP), which is associated with higher risk of sudden cardiac death. Little is known about the prescription and dispensation patterns of QT-prolonging medications among people receiving dialysis, hindering efforts to reduce drug-related harm from these and other medications in this high-risk population.

Objective: To examine prescription and dispensation patterns of QT-prolonging medications with known TdP risk and selected interacting medications prescribed to individuals receiving hemodialysis.

Individuals with kidney failure undergoing maintenance dialysis frequently report a high symptom burden that can interfere with functioning and diminish life satisfaction. Until recently, the focus of nephrology care for dialysis patients has been related primarily to numerical targets for laboratory measures, and outcomes such as cardiovascular disease and mortality. Routine symptom assessment is not universal or standardized in dialysis care.

Rationale & Objective: Treatment with certain QT interval-prolonging antibiotics is associated with a higher risk of sudden cardiac death among individuals with hemodialysis-dependent kidney failure. Concurrent exposure to large serum-to-dialysate potassium gradients, which promote large potassium shifts, may augment the proarrhythmic effects of these medications. The primary objective of this study was to examine whether the serum-to-dialysate gradient modifies the cardiac safety of azithromycin, and separately, levofloxacin/moxifloxacin.
