Study Notes
Kidney Disease Assessment and Management
- Kidney function assessed via glomerular filtration rate (GFR) from serum creatinine.
- GFR evaluation crucial for disease severity, progression monitoring, and treatment response.
- Diagnosis includes urinalysis (looking for albuminuria, hematuria, casts), quantified albuminuria, ultrasound, nephrologist referral, and biopsy.
- Referrals more likely with rapid function decline, albumin-to-creatinine ratio over 300 mg/g, or urinary red blood cell casts.
Chronic Kidney Disease (CKD) Natural History
- Kidney injury manifestations range from asymptomatic hematuria to needing dialysis.
- Many recover fully; others experience chronic damage (like in lupus nephritis).
- Some previously inactive or cured diseases can progress due to factors like hemodynamics.
- Kidney adaptation to injury: adaptive hyperfiltration (increased undamaged nephron filtration).
- Adaptive hyperfiltration, helpful initially, leads to glomerular damage, albuminuria, and kidney failure.
- Hyperfiltration risks linked to progression factors: obesity, family history, glomerulosclerosis, arteriosclerosis.
Progressive Kidney Failure
- Initial CKD decline asymptomatic.
- Advanced failure signs/symptoms: volume overload, hyperkalemia, metabolic acidosis, hypertension, anemia, mineral bone disorders (MBDs).
- End-stage kidney disease (ESKD) characterized by uremia symptoms (e.g., anorexia, nausea, pericarditis, neuropathy, CNS issues).
- Uremia symptoms independent of BUN/creatinine/GFR levels; some patients symptomatic despite low levels, others asymptomatic despite high levels.
- Treatment for uremia requiring kidney replacement therapy (hemodialysis, peritoneal dialysis, or transplantation).
CKD Progression Variability
- Not everyone's kidney function progressively deteriorates.
- Progression rate varies based on underlying disease, comorbidities, treatments, socioeconomic factors, genetics, ethnicity, and acute kidney injuries (AKIs).
- Estimated GFR decline between 15-60 mL/min/1.73 m2 to ESKD approximately 1.5% per year.
