Amyloidosis of kidney may be seen in the following except-
**Core Concept**
Amyloidosis refers to the deposition of **amyloid fibrils** in various tissues, leading to organ dysfunction. In the context of the kidney, amyloidosis can cause **nephrotic syndrome** or **renal failure**. The underlying principle involves the accumulation of misfolded proteins.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general causes of amyloidosis in the kidney. **Primary amyloidosis** (AL amyloidosis) is associated with **monoclonal gammopathy**, where abnormal light chain proteins are produced. **Secondary amyloidosis** (AA amyloidosis) occurs in response to chronic inflammation, such as in **rheumatoid arthritis** or **chronic infections**.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option text, it's challenging to provide a detailed explanation. However, common causes of amyloidosis include **chronic diseases** and **familial amyloidosis**.
**Option B:** Similarly, without the text, it's difficult to address. However, **age-related amyloidosis** and **dialysis-related amyloidosis** are other forms.
**Option C:** Again, lacking the text, but **familial Mediterranean fever** is a known cause of amyloidosis.
**Option D:** This option is also unspecified, but **hemodialysis** can be associated with **beta-2 microglobulin amyloidosis**.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **amyloidosis** can present with **non-selective proteinuria**, indicating significant kidney damage. Recognizing the association between amyloidosis and underlying diseases is crucial for diagnosis.
**Correct Answer:** Not provided in the question.
