Thickening of basement membrane of glomeruli is seen in –
**Core Concept**
The basement membrane of glomeruli is a critical component of the glomerular filtration barrier, composed of type IV collagen, laminin, and other proteins. Thickening of the basement membrane can disrupt the normal filtration process, leading to kidney dysfunction.
**Why the Correct Answer is Right**
The correct answer is associated with **Diabetic Nephropathy**. In diabetic nephropathy, the thickening of the basement membrane is a result of the accumulation of advanced glycosylation end-products (AGEs) and the activation of the renin-angiotensin-aldosterone system (RAAS). This leads to an increase in the synthesis of extracellular matrix proteins, including type IV collagen, resulting in the thickening of the basement membrane. The increased thickness impairs the glomerular filtration barrier, leading to proteinuria and progressive kidney damage.
**Why Each Wrong Option is Incorrect**
* **Option A:** Focal Segmental Glomerulosclerosis (FSGS) is a disease characterized by the scarring of glomeruli, but it is not primarily associated with the thickening of the basement membrane.
* **Option B:** Minimal Change Disease is a disease characterized by the loss of foot processes of podocytes, but it is not associated with the thickening of the basement membrane.
* **Option C:** Membranoproliferative Glomerulonephritis is a disease characterized by the proliferation of cells and the thickening of the basement membrane, but it is not the most common cause of basement membrane thickening.
**Clinical Pearl / High-Yield Fact**
The thickening of the basement membrane is a hallmark of diabetic nephropathy, and it can be detected using electron microscopy or immunofluorescence staining.
**Correct Answer:** B. Minimal Change Disease is a disease characterized by the loss of foot processes of podocytes, but it is not associated with the thickening of the basement membrane.
