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
Dimension
Nephrotic Syndrome
Nephritic Syndrome
Mechanism & causes
  • Glomerular membrane leaks protein
  • Minimal change disease (children)
  • Diabetes, lupus, amyloidosis
  • Glomerular inflammation damages capillaries
  • Post-streptococcal GN (children)
  • IgA nephropathy, lupus, Goodpasture
Urine, edema & BP
  • ★Foamy/frothy urine (massive protein)
  • Generalized edema, anasarca
  • BP normal/low
  • ★Cola-/tea-colored urine (RBCs)
  • Periorbital edema
  • HTN
  • oliguria
Diagnostics & labs
  • Massive proteinuria > 3.5 g/day
  • Albumin <2.5
  • hyperlipidemia
  • ★Hematuria with RBC casts
  • Proteinuria <3.5
  • ↑BUN/Cr (azotemia)
Nursing priorities
  • Daily weight, I&O, assess edema
  • Infection prevention (lost immunoglobulins)
  • Monitor BP, I&O, urine color
  • Watch oliguria & azotemia
  • daily weights
Management
  • Corticosteroids (esp. minimal change)
  • Albumin, statin
  • ACEi/ARB to ↓ proteinuria
  • Treat underlying cause/inflammation
  • Antihypertensives, diuretics
  • antibiotics if strep
Patient teaching
  • Low-sodium diet
  • report fever/infection
  • Take steroids as prescribed
  • don't stop abruptly
  • Sodium & fluid restriction
  • complete strep abx
  • Report ↓/dark urine, swelling
Red flags — escalate
  • Sudden dyspnea/leg pain then thromboembolism
  • Signs of infection (peritonitis, sepsis)
  • Severe HTN, headache then encephalopathy
  • Rising BUN/Cr, anuria then acute renal failure
Complications
  • ★Thromboembolism (lost antithrombin III)
  • Infection, malnutrition, AKI
  • Hypertensive crisis, fluid overload
  • Progression to chronic GN / CKD

★ marks the fact that sets a column apart.

Clinical Pearl

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