Minimal Change Disease (MCD)
Minimal Change Disease (MCD)
A common type of nephrotic syndrome in children, often with no known cause. It can sometimes be linked to Hodgkin lymphoma.
Focal Segmental Glomerulosclerosis (FSGS)
Focal Segmental Glomerulosclerosis (FSGS)
A leading cause of nephrotic syndrome among Hispanic and African American individuals, often with no clear reason. There can be a connection to HIV, heroin use, or sickle cell disease.
Membranous Nephropathy
Membranous Nephropathy
A type of nephrotic syndrome most common in white adults, often without a known cause. It's sometimes linked to conditions like hepatitis B or C, tumors, lupus, or certain medications.

Study Notes
Nephrotic Syndrome
- Characterized by proteinuria greater than 3.5 grams per day
- Leads to hypoalbuminemia (low albumin) causing pitting edema
- Also causes hypogammaglobulinemia (low immunoglobulins), increasing infection risk
- Associated with a hypercoagulable state due to antithrombin III loss
- Hyperlipidemia and hypercholesterolemia may result in fatty casts in urine
Minimal Change Disease (MCD)
- Most common cause of nephrotic syndrome in children
- Usually idiopathic (no known cause)
- May be associated with Hodgkin lymphoma
Focal Segmental Glomerulosclerosis (FSGS)
- Common nephrotic syndrome cause among Hispanics and African Americans
- Often idiopathic, but associated with HIV, heroin use, and sickle cell disease
- Characterized by focal and segmental sclerosis in glomeruli
- Shows effacement of foot processes on EM (electron microscopy)
- Poor response to steroids, often progressing to chronic renal failure
Membranous Nephropathy
- Most common nephrotic syndrome in Caucasians
- Often idiopathic but associated with Hepatitis B or C, cancers, or autoimmune diseases
- Characterized by thick glomerular basement membrane
- Subepithelial deposits with "spike and dome" appearance on EM (electron microscopy)
- Poor response to steroids, progresses to chronic renal failure
Membranoproliferative Glomerulonephritis
- Characterized by a thick glomerular basement membrane often with a "tram-track" appearance
- Caused by immune complex deposition, indicated by granular immunofluorescence
- Two types: Type I (subendothelial deposits; often with HBV and HCV) and Type II (intramembranous deposits; associated with C3 nephritic factor)
- Often poor response to steroids, progresses to chronic renal failure
Diabetes Mellitus
- High serum glucose causes non-enzymatic glycosylation of the glomerular basement membrane
- Results in hyaline arteriolosclerosis
Systemic Amyloidosis
- Kidney is a common target organ
- Characterized by amyloid deposits in the mesangium, causing nephrotic syndrome
- Shows apple-green birefringence under polarized light after Congo red staining
