Insights

Korean dialysis patients face significant burdens from chronic kidney disease-mineral bone disorder. This study proposes practical recommendations for managing abnormal serum phosphorus, calcium, and intact parathyroid hormone (iPTH) levels.

Area of Science:

  • Nephrology
  • Endocrinology
  • Bone Metabolism

Background:

  • Chronic kidney disease-mineral bone disorder (CKD-MBD) poses a significant threat to Korean dialysis patients, linked to cardiovascular calcification and mortality.
  • Epidemiologic data reveal many patients on maintenance hemodialysis fall outside target ranges for serum calcium, phosphorus, and intact parathyroid hormone (iPTH).

Purpose of the Study:

  • To address the need for practical recommendations for managing abnormal serum phosphorus, calcium, and iPTH in dialysis patients.
  • To propose simplified medication adjustment strategies for optimal management of secondary hyperparathyroidism.

Main Methods:

  • Review of current practices regarding measurement of serum calcium, phosphorus, and iPTH.
  • Discussion of dialysate calcium concentration, dietary phosphorus restriction, and phosphate binders.
  • Evaluation of medical and surgical options for correcting secondary hyperparathyroidism.

Main Results:

  • A simplified medication adjustment strategy is suggested based on serum phosphorus and calcium levels for managing secondary hyperparathyroidism.
  • Current management practices and options are briefly commented upon.

Conclusions:

  • Development of practical recommendations is necessary for treating abnormal mineral and bone metabolism in dialysis patients.
  • Large-scale clinical studies are required to validate proposed strategies and establish practice guidelines for improved patient outcomes.

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Chronic Kidney Disease IV: Nursing Management

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...
