[Thromboembolic complications in nephrotic syndrome]

Area of Science:

• Nephrology
• Hematology
• Internal Medicine

Context:

• Thromboembolic events are significant non-kidney complications of nephrotic syndrome (NS).
• Hypercoagulability in NS results from disrupted hemostatic balance, increased blood viscosity, and endothelial dysfunction.
• Specific factors like anti-α-enolase antibodies and renal elimination of molecules contribute to thrombosis risk in idiopathic membranous nephropathy.

Purpose:

• To summarize the pathophysiology of thromboembolic complications in nephrotic syndrome.
• To identify key risk factors and indicators for thrombosis in NS patients.
• To outline current clinical recommendations for prophylactic anticoagulation in high-risk NS individuals.

Summary:

• Nephrotic syndrome (NS) disrupts hemostasis, leading to hypercoagulability and increased risk of deep vein thrombosis, pulmonary embolism, and renal vein thrombosis.
• Low serum albumin concentration is a critical indicator of thrombosis risk in NS patients.
• The KDIGO guideline recommends primary prophylactic anticoagulation for NS patients with albumin <25 g/l and an additional risk factor, continuing until albumin levels reach 30 g/l.

Impact:

• Provides a comprehensive overview of thrombosis in NS, aiding clinical decision-making.
• Highlights the importance of monitoring serum albumin and implementing prophylactic measures.
• Contributes to improved patient outcomes by mitigating severe thromboembolic events in nephrotic syndrome.
