Following are features of Acute GN except:
**Core Concept**
Acute glomerulonephritis (GN) is an inflammatory condition of the glomeruli, which are the filtering units of the kidneys. The exact cause of acute GN can vary, but it often involves an immune response triggered by infections, such as streptococcal pharyngitis or skin infections.
**Why the Correct Answer is Right**
Acute GN is characterized by the presence of hematuria, proteinuria, and oliguria. The hematuria is typically microscopic, but it can be macroscopic in some cases. The proteinuria is usually non-nephrotic, meaning that the protein loss is not excessive. The oliguria is due to the inflammatory process affecting the glomeruli, leading to decreased kidney function. The classic example of acute GN is post-streptococcal GN (PSGN), which occurs after a streptococcal infection.
**Why Each Wrong Option is Incorrect**
**Option A:** Hematuria and proteinuria are common features of acute GN, so this option is incorrect.
**Option B:** Oliguria is a characteristic feature of acute GN, so this option is incorrect.
**Option C:** This option is incomplete, please provide the actual options.
**Clinical Pearl / High-Yield Fact**
It's essential to note that the exact cause of acute GN can vary, and PSGN is a classic example. However, other causes such as IgA nephropathy, lupus nephritis, and ANCA-associated vasculitis can also present with acute GN.
