    Study Notes

    Diuretic Resistance

    • Diuretic resistance (DR) is a common issue in patients with kidney diseases and renal edema.
    • DR occurs when diuretics become ineffective or weakened in treating edema.
    • DR increases the risk of readmission and mortality in patients with kidney diseases.

    Causes of Diuretic Resistance

    • Poor Diet:
      • Electrolyte disturbance
      • Hypoproteinemia
    • Poor Drug Compliance:
      • Inadequate diuretic dosage
    • Pharmacokinetic and Pharmacodynamic Changes:
      • Altered drug absorption, distribution, metabolism, and excretion
      • Reduced drug effectiveness
    • Electrolyte Disorders:
      • Alterations in sodium, potassium, and other electrolyte levels
    • Renal Adaptation:
      • Changes in kidney's response to diuretics over time
    • Functional Nephron Reduction:
      • Decreased number of functioning nephrons, leading to reduced diuretic action
    • Decreased Renal Blood Flow:
      • Inadequate blood supply to the kidneys, impairing diuretic efficacy

    Treatment Strategies for Diuretic Resistance

    • Increasing Diuretic Dose and/or Frequency:
      • Enhancing diuretic effect by increasing dosage or administration frequency
    • Sequential Nephron Blockade:
      • Using multiple diuretics with different mechanisms of action
    • New Diuretics:
      • Exploring effective newer diuretics with improved efficacy
    • Ultrafiltration Treatment:
      • Removing excess fluid from the body through a filtration process

    Research and Future Directions

    • Research on DR in patients with heart disease is extensive.
    • However, comprehensive research on the mechanisms and treatment strategies for DR specifically in patients with kidney diseases is limited.
    • This review aims to bridge this gap by providing information to clinicians and researchers, potentially expanding research avenues and ideas.
