All are true about minimal change GN except?
**Core Concept**
Minimal change glomerulopathy (MCGN) is a type of nephrotic syndrome characterized by the loss of foot processes of podocytes on electron microscopy. It is often associated with heavy proteinuria, hypoalbuminemia, and hyperlipidemia.
**Why the Correct Answer is Right**
The pathophysiology of MCGN involves the loss of the glomerular filtration barrier, allowing large molecules like albumin to pass through into the urine. This is often due to the activation of the complement system and the production of autoantibodies against the glomerular basement membrane. The condition is typically responsive to corticosteroids, which suppress the immune system and reduce proteinuria.
**Why Each Wrong Option is Incorrect**
**Option A:** MCGN is indeed characterized by minimal changes on light microscopy, which is where the name originates. This is a true statement.
**Option B:** The condition is often associated with a poor prognosis if left untreated, which is why early intervention with corticosteroids is crucial. This is a true statement.
**Option C:** MCGN is not typically associated with the presence of hematuria, which is more characteristic of other types of glomerulonephritis. This is a false statement.
**Option D:** The condition is often seen in children, but it can also occur in adults. This is a true statement.
**Clinical Pearl / High-Yield Fact**
MCGN is often associated with the presence of nephrotic range proteinuria, which is defined as a protein excretion of >3.5 g/24 hours.
**Correct Answer:** C. MCGN is not typically associated with the presence of hematuria.
