Nephrotic vs Nephritic Syndrome: Protein Loss vs Inflammatory Damage

One syndrome leaks protein, the other leaks blood — but they're one letter apart, and NCLEX questions hinge on whether you pick "foamy urine with edema" or "cola-colored urine with hypertension." Swapping these loses the question every time.

Comparison

Side-by-side2 compared
Focus
Dimension
Nephrotic Syndrome
Nephritic Syndrome
Mechanism & causes
  • Glomerular membrane leaks protein
  • Minimal change disease (children)
  • Diabetes, amyloidosis
  • Lupus (SLE)
  • Inflamed glomeruli leak RBCs
  • Post-streptococcal GN (children)
  • IgA nephropathy, Goodpasture
  • Lupus (SLE)
Urine, edema & BP
  • ★Foamy/frothy urine (massive protein)
  • Generalized edema, anasarca
  • BP normal or low
  • Periorbital edema
  • ★Cola-/tea-colored urine (RBCs)
  • Periorbital edema
  • Hypertension
  • Oliguria
Diagnostics & labs
  • Massive proteinuria > 3.5 g/day
  • Serum albumin <3 g/dL
  • Hyperlipidemia, lipiduria
  • ★Hematuria with RBC casts
  • Mild proteinuria (<3.5 g/day)
  • ↑BUN/Cr (azotemia)
Nursing priorities
  • Daily weights, strict I&O
  • Infection prevention (lost IgG)
  • Skin care for anasarca
  • Monitor BP and urine color
  • Watch for oliguria, ↑BUN/Cr
  • Daily weights, strict I&O
Management
  • Corticosteroids (esp. minimal change)
  • Statin for hyperlipidemia
  • ACEi/ARB to ↓ proteinuria
  • Loop diuretics for edema
  • Loop diuretics for edema
  • BP control: antihypertensives
  • Antibiotics if active strep
Patient teaching
  • Low-sodium diet
  • Report fever or infection
  • Never stop steroids abruptly
  • Low-sodium diet
  • Finish the full antibiotic course
  • Report dark or ↓ urine
  • Fluid restriction if oliguric
Red flags — escalate
  • Leg pain/dyspnea = clot (DVT/PE)
  • Signs of infection (peritonitis, sepsis)
  • Severe HTN + headache → encephalopathy
  • Rising BUN/Cr, anuria = AKI
Complications
  • ★Thromboembolism (lost antithrombin III)
  • Infection, malnutrition
  • Progression to CKD
  • Hypertensive crisis, fluid overload
  • Progression to CKD

Clinical Pearl

Nephr-O-tic = prOtein Out (foamy urine, edema). Nephr-I-tic = Inflamed, blood In (cola urine, HTN).
