All are true of Nephrotic syndrome, except
**Core Concept**
Nephrotic syndrome is a kidney disorder characterized by severe loss of protein in the urine, leading to hypoalbuminemia, edema, and hyperlipidemia. It is often associated with various underlying causes, including glomerular diseases, systemic conditions, and medications.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of nephrotic syndrome. Nephrotic syndrome is characterized by the loss of large amounts of albumin (a protein crucial for maintaining blood volume and osmotic pressure) in the urine due to damage to the glomerular filtration barrier. This leads to hypoalbuminemia, which triggers a cascade of events resulting in edema, hyperlipidemia, and increased risk of infections and thrombosis.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is a characteristic of nephrotic syndrome. Proteinuria is a hallmark of the condition, with patients often excreting more than 3.5 g of protein per day.
**Option B:** Hyperlipidemia is a common feature of nephrotic syndrome due to increased hepatic lipoprotein synthesis in response to hypoalbuminemia. This makes option B incorrect, as it is a true statement.
**Option C:** Edema is a common symptom of nephrotic syndrome, resulting from the loss of albumin and subsequent decrease in oncotic pressure. This makes option C incorrect, as it is a true statement.
**Clinical Pearl / High-Yield Fact**
A classic exam trap is the distinction between nephrotic and nephritic syndromes. Nephrotic syndrome is characterized by massive proteinuria, hypoalbuminemia, and hyperlipidemia, whereas nephritic syndrome is characterized by hematuria, hypertension, and mild proteinuria. This distinction is crucial for differentiating between various underlying causes.
**Correct Answer:** None of the above statements are false regarding nephrotic syndrome.
