Chronic hyperkalemia in non-dialysis CKD: controversial issues in nephrology practice

Area of Science:

• Nephrology
• Internal Medicine
• Clinical Pharmacology

Background:

• Chronic hyperkalemia is a frequent complication of chronic kidney disease (CKD), associated with poor prognosis.
• Current management strategies for hyperkalemia in CKD patients are often suboptimal, despite optimal care settings.
• Hyperkalemia necessitates careful management by nephrologists due to its prevalence and impact.

Purpose of the Study:

• To identify and discuss unresolved issues in the management of chronic hyperkalemia in non-dialysis CKD patients.
• To provide opinion-based answers on controversial topics concerning hyperkalemia in CKD.
• To review current diagnostic and therapeutic approaches and explore new treatment options.

Main Methods:

• Literature review and synthesis of current evidence.
• Discussion of clinical topics including diagnosis and comorbidities.
• Evaluation of current and emerging therapeutic strategies, including dietary and pharmacological treatments.

Main Results:

• Unresolved issues in diagnosis and the relationship between hyperkalemia and CKD comorbidities were identified.
• The efficacy of current dietary and pharmacological treatments for hyperkalemia was critically assessed.
• The potential role of novel potassium binders in managing hyperkalemia was explored.

Conclusions:

• Effective management of chronic hyperkalemia in non-dialysis CKD requires addressing several unresolved clinical issues.
• Further research and optimized therapeutic strategies are needed to improve hyperkalemia control in CKD.
• Newer potassium binders may offer promising solutions for managing this complex complication.
