Study Notes
Learning Objectives
- Classify Chronic Kidney Disease (CKD) stages and types.
- Identify risk factors influencing the development and progression of CKD.
- Recognize typical clinical presentations and complications associated with CKD.
- Develop strategies to slow CKD progression.
- Manage complications arising from CKD.
- Understand various renal replacement therapies.
Definition and Effects of CKD
- CKD is characterized by kidney damage or a glomerular filtration rate (GFR) below 60 ml/min/1.73m² for three months or longer.
- It is typically a long-term, preventable health condition.
- Damage occurs to both glomeruli and tubules, often remaining asymptomatic until significant kidney function is lost (GFR ~10-15 ml/min).
Kidney Disease Crisis in Australia
- CKD presents a significant health challenge in Australia, contributing to a healthcare financial strain of approximately $647 million annually.
Management Strategies
- Assess cardiovascular disease (CVD) risk as CKD often correlates with increased risk.
- Implement comprehensive CKD management focusing on kidney protection, progression delay, and consequence management.
Hypertension in CKD
- Hypertension is both a symptom and a cause of CKD progression; managing blood pressure can slow this progression.
- First-line agents for managing hypertension in CKD include ACE inhibitors (ACEIs) and Angiotensin II receptor antagonists (ARBs), especially effective for diabetic nephropathy.
- Patients often require a combination of medications to effectively manage blood pressure.
Proteinuria and Albuminuria
- The level of proteinuria is a strong predictor of CKD progression; significant proteinuria indicates a worse prognosis, while its absence suggests a favorable outlook.
- Recommended protein intake is 0.6-0.8 g/kg/day, avoiding high-protein diets.
- Common treatments include ACEIs/ARBs, sodium reduction, and SGLT2 inhibitors.
Dyslipidaemia in CKD
- CKD commonly results in lipid metabolism abnormalities, including elevated LDL, triglycerides, and reduced HDL cholesterol, particularly in patients with albuminuria.
- Statins are recommended for patients aged 50 or older at any CKD stage and for those under 50 with cardiovascular risk factors.
Glucose Control and CKD Risk Reduction
- Optimal glycemic control substantially decreases the risk of micro and macroalbuminuria in both type 1 and type 2 diabetes.
- Management strategies include lifestyle changes, oral hypoglycemic agents, and SGLT2 inhibitors.
Sodium and Fluid Management
- Sodium excretion is maintained until GFR is significantly reduced; once this threshold is reached, sodium and fluid retention can cause hypertension and edema.
- Sodium intake is generally restricted to 2-4g/day and fluid intake is about 2L/day, though this can vary by patient.
- Diuretics are often employed to manage extracellular fluid volume and enhance the effects of antihypertensive drugs.
