In Nephrotic syndrome hypercoaguability occurs due to-
**Core Concept**
Hypercoagulability in nephrotic syndrome is a life-threatening complication that arises due to the loss of anticoagulant proteins in the urine. This phenomenon is a result of the glomerular damage and subsequent massive proteinuria, which leads to a decrease in the levels of antithrombin III, protein C, and protein S.
**Why the Correct Answer is Right**
The loss of anticoagulant proteins in the urine impairs the body's ability to regulate blood coagulation, leading to an increased risk of thrombosis. Antithrombin III, protein C, and protein S are essential in preventing the formation of blood clots by inhibiting the coagulation cascade. With their decreased levels, the coagulation system becomes unopposed, resulting in hypercoagulability. This is further exacerbated by the increased levels of pro-coagulant proteins such as factor V and factor VIII.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the pathophysiology of hypercoagulability in nephrotic syndrome.
* **Option B:** While inflammation can contribute to hypercoagulability, it is not the primary mechanism in nephrotic syndrome.
* **Option D:** Renal failure can lead to various complications, but it is not directly responsible for hypercoagulability in nephrotic syndrome.
**Clinical Pearl / High-Yield Fact**
Nephrotic syndrome patients are at an increased risk of developing venous thromboembolism, particularly pulmonary embolism, which can be fatal. It is essential to monitor these patients closely for signs of hypercoagulability and thrombosis.
**Correct Answer:** C.
