What is the management plan for a 77-year-old male with stage 4 Chronic Kidney Disease (CKD)?

From the Guidelines

The management plan for a 77-year-old male with stage 4 CKD should focus on slowing disease progression, managing complications, and preparing for potential renal replacement therapy, with referral to a nephrologist for co-management if not already done, as recommended by 1.

Key Components of Management

• Blood pressure control is essential, targeting <130/80 mmHg, typically using an ACE inhibitor (like enalapril 5-20 mg daily) or ARB (such as losartan 25-100 mg daily) as first-line therapy, as supported by 1.
• Glycemic control for diabetic patients should aim for HbA1c of 7-8%, avoiding hypoglycemia, in line with general guidelines for diabetes management.
• Dietary modifications include:
  • Restricting sodium to <2g/day
  • Potassium restriction if hyperkalemic
  • Phosphorus limitation to 800-1000 mg/day
  • Protein intake of 0.8 g/kg/day, as suggested by 1 for patients with CKD.
• Metabolic acidosis should be treated with oral sodium bicarbonate 650-1300 mg three times daily to maintain serum bicarbonate >22 mEq/L.
• Anemia management includes iron supplementation (ferrous sulfate 325 mg daily) if iron-deficient, and erythropoiesis-stimulating agents like darbepoetin alfa if hemoglobin falls below 10 g/dL.
• For mineral bone disorder, phosphate binders (calcium acetate 667 mg with meals) and vitamin D analogs (calcitriol 0.25 mcg daily) may be needed, as outlined in 1.

Monitoring and Education

• Regular monitoring should include quarterly labs (electrolytes, BUN, creatinine, calcium, phosphorus, PTH, hemoglobin) and annual screening for albuminuria.
• The patient should receive vaccinations (influenza, pneumococcal, hepatitis B) and education about kidney failure treatment options, including dialysis modalities and transplantation evaluation if appropriate, as emphasized by 1.
• Medication review is crucial to avoid nephrotoxic drugs and adjust dosages for declining kidney function.

From the FDA Drug Label

Of the 4553 patients who received PROCRIT in the 6 studies for treatment of anemia due to CKD not receiving dialysis, 2726 (60%) were age 65 years and over, while 1418 (31%) were 75 years and over. No differences in safety or effectiveness were observed between geriatric and younger patients. Dose selection and adjustment for an elderly patient should be individualized to achieve and maintain the target hemoglobin [see Dosage and Administration (2)]

The management plan for a 77-year-old male with stage 4 Chronic Kidney Disease (CKD) should be individualized, with dose selection and adjustment made to achieve and maintain the target hemoglobin level.

• No differences in safety or effectiveness were observed between geriatric and younger patients.
• The patient's age alone is not a determining factor in the management plan. 2

From the Research

Management Plan for a 77-year-old Male with Stage 4 Chronic Kidney Disease (CKD)

The management plan for a 77-year-old male with stage 4 CKD involves several key components, including dietary modifications, monitoring of kidney function, and management of related complications.

• Dietary Modifications: A low-protein diet (LPD) is often recommended for the management of CKD, as it can help slow the progression of the disease and reduce the risk of complications 3, 4. The recommended protein intake for CKD patients is 0.6-0.8 g/kg/day.
• Monitoring of Kidney Function: Regular monitoring of kidney function, including measurements of serum creatinine, urea, and electrolytes, is essential to assess the progression of CKD and adjust the management plan as needed.
• Management of Related Complications: CKD is often associated with other complications, such as anemia, hypertension, and electrolyte imbalances. Management of these complications is crucial to prevent further deterioration of kidney function and reduce the risk of cardiovascular disease.
• Medication Management: Certain medications, such as angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), can help slow the progression of CKD and reduce proteinuria.
• Lifestyle Modifications: Lifestyle modifications, such as regular exercise, weight loss (if obese), and smoking cessation, can also help manage CKD and reduce the risk of complications.

Dietary Management

Dietary management plays a critical role in the management of CKD. A LPD can help reduce the workload on the kidneys and slow the progression of the disease.

• Low-Protein Diet: A LPD with a protein intake of 0.6-0.8 g/kg/day is recommended for CKD patients 3, 4.
• Phosphorus Restriction: Phosphorus restriction is also important, as high phosphorus levels can contribute to the progression of CKD.
• Electrolyte Management: Management of electrolytes, such as potassium, sodium, and calcium, is crucial to prevent complications such as hyperkalemia and hypocalcemia.

Anemia Management

Anemia is a common complication of CKD, and management of anemia is essential to prevent further deterioration of kidney function and reduce the risk of cardiovascular disease.

• Erythropoiesis-Stimulating Agents: Erythropoiesis-stimulating agents, such as darbepoetin alfa and continuous erythropoietin receptor activator, can be used to manage anemia in CKD patients 5.
• Iron Supplementation: Iron supplementation may also be necessary to manage anemia in CKD patients.

Transition to Dialysis

For patients with advanced CKD, transition to dialysis may be necessary.

• Incremental Transition: An incremental transition to dialysis, with less frequent hemodialysis sessions at the beginning and gradual increase in frequency over time, may be beneficial in preserving residual kidney function 6.
• Dietary Management: Dietary management, including a LPD and phosphorus restriction, is crucial during the transition to dialysis to prevent complications and preserve residual kidney function.
