Chronic Kidney Disease

Chronic Kidney Disease (CKD) is characterized by gradual, irreversible loss of renal function lasting at least three months. It is defined by a glomerular filtration rate (GFR) of less than 60 mL/min/1.73 m² or the presence of markers of kidney damage (e.g., albuminuria).

• Diabetic Nephropathy: Most common cause globally.
• Hypertensive Nephrosclerosis: Chronic high systemic pressure damages renal vasculature.
• Glomerulonephritis: Immunological injury to glomeruli (e.g., IgA nephropathy).
• Genetic Factors: Autosomal dominant polycystic kidney disease (ADPKD).
• Tubulointerstitial Nephritis: Chronic exposure to nephrotoxins (NSAIDs, heavy metals).
• Obstructive Uropathy: Chronic urinary tract obstruction (e.g., benign prostatic hyperplasia).

Loss of functioning nephrons leads to compensatory hyperfiltration and hypertrophy of remaining nephrons. This maladaptive response induces intraglomerular hypertension, mediated by angiotensin II. Over time, physical stress damages the glomerular filtration barrier, resulting in proteinuria, progressive glomerulosclerosis, tubulointerstitial fibrosis, and declining GFR.

• Prevalence: Affects approximately 10–13% of the global adult population.
• Demographics: Higher prevalence in individuals over 65 years, females, and ethnic minorities (African Americans, Hispanics).

• Diabetes mellitus
• Systemic hypertension
• Cardiovascular disease
• Obesity
• Family history of CKD
• Older age (>60 years)
• Frequent acute kidney injury (AKI) episodes

• Vitals: Hypertension, tachypnea (in acidosis/fluid overload).
• Inspection: Pale conjunctiva (anemia), uremic frost (rare, advanced), excoriations (pruritus), pitting peripheral edema.
• Palpation: Enlarged kidneys (in ADPKD).
• Auscultation: Crackles/rales (pulmonary edema), pericardial friction rub (uremic pericarditis).

• Clinical Assessment: History of diabetes, hypertension, and medication use.
• Laboratory Testing: Comprehensive metabolic panel, CBC, urinalysis.
• Imaging Studies: Renal ultrasonography to evaluate size, echogenicity, and rule out obstruction.
• Functional Tests: 24-hour urine collection (rarely needed if spot ratios are available).
• Biopsy Findings: Indicated when the etiology is unclear (shows glomerulosclerosis, interstitial fibrosis).
• Genetic Testing: Performed if ADPKD or Alport syndrome is suspected.
• Differential Diagnosis: AKI, prerenal azotemia, postrenal obstruction.

Serum Creatinine and eGFR
Type: Blood Test
Purpose: Estimate glomerular filtration rate and stage CKD.
Expected Findings: Elevated serum creatinine; eGFR < 60 mL/min/1.73 m².
Interpretation: Diagnostic of CKD if sustained for $\ge 3$ months. Urine Albumin-to-Creatinine Ratio (UACR)
Type: Urine Test (Spot sample)
Purpose: Detect and quantify glomerular protein leakage.
Expected Findings: Elevated albuminuria (>30 mg/g).
Interpretation: Indicates severity of glomerular damage and risk of progression.

Renal Ultrasound: Purpose: Assess renal size, cortical thickness, and rule out hydronephrosis. Findings: Typically reveals small (<9 cm), bilaterally echogenic kidneys with thinned cortices (except in diabetic nephropathy or amyloidosis, where kidneys may be normal or enlarged). Clinical Importance: Confirms chronicity and excludes reversible obstructive causes.

• Acute Kidney Injury (AKI): Distinguished by rapid creatinine rise, normal kidney size on ultrasound, and reversible etiology.
• Prerenal Azotemia: Transient decrease in renal perfusion; responds rapidly to volume resuscitation.
• Postrenal Obstruction: Acute hydronephrosis visible on ultrasound, resolved by urinary decompression.

• Cardiovascular disease (leading cause of death)
• Hyperkalemia and metabolic acidosis
• Renal osteodystrophy (CKD-Mineral and Bone Disorder)
• Anemia of chronic disease
• Uremic pericarditis and encephalopathy

CKD is a progressive, irreversible condition. The rate of decline varies by etiology and control of comorbidities. Stage 5 CKD (ESRD, GFR < 15) requires renal replacement therapy (RRT) for survival. Cardiovascular mortality is significantly elevated in CKD patients.

• Aggressive glycemic and blood pressure control (<130/80 mmHg).
• Early screening with eGFR and UACR in high-risk individuals.
• Avoiding nephrotoxic medications.
