II. Epidemiology

  1. Accounts for one third of Nephrotic Syndrome in adults
  2. Peak Incidence 30 to 50 years old

III. Causes

  1. Idiopathic (75%)
  2. Systemic Lupus Erythematosus
  3. Hepatis B Virus Infection
  4. Drug-induced Nephrotic Syndrome
  5. Cancer

IV. Labs

  1. Urinalysis
    1. Microscopic Hematuria (variably present)

V. Labs: Pathology

  1. Thickening of glomerular basement membrane on electron microscopy
  2. IgG and C3 depositis with immunofluorescent stains

Ontology: Membranous glomerulonephritis (C0017665)

Definition (CSP) characterized histologically by proteinaceous deposits on the glomerular capillary basement membrane or by thickening of the membrane; clinically similar to chronic glomerulonephritis, occasionally with transient nephrotic syndrome.
Definition (MSH) A type of glomerulonephritis that is characterized by the accumulation of immune deposits (COMPLEMENT MEMBRANE ATTACK COMPLEX) on the outer aspect of the GLOMERULAR BASEMENT MEMBRANE. It progresses from subepithelial dense deposits, to basement membrane reaction and eventual thickening of the basement membrane.
