1. Renal Pathology — Nephrotic Syndrome
Hypercoagulability
A 34-year-old woman presents with progressive
lower-extremity edema and frothy urine
developing over several weeks. Laboratory
studies demonstrate severe hypoalbuminemia,
hyperlipidemia, and proteinuria measuring 8.2
g/day. Renal biopsy shows diffuse thickening of
the glomerular basement membrane with
subepithelial immune complex deposits. Three
,days after admission, she develops sudden
pleuritic chest pain and dyspnea.
Which pathophysiologic alteration most directly
predisposed this patient to her acute
complication?
A. Increased hepatic synthesis of fibrinogen
secondary to systemic inflammation
B. Urinary loss of antithrombin III causing
impaired endogenous anticoagulation
C. Endothelial injury from circulating anti-
basement membrane antibodies
D. Reduced platelet adhesion caused by
nephrotic-range albumin loss
E. Suppression of coagulation factor synthesis
due to hepatic dysfunction
Correct Answer
B. Urinary loss of antithrombin III causing
impaired endogenous anticoagulation
,Clinical Clue Interpretation
The combination of massive proteinuria,
hypoalbuminemia, hyperlipidemia, and diffuse
membranous nephropathy findings establishes
a nephrotic syndrome.
The development of sudden pleuritic chest pain
strongly suggests pulmonary
thromboembolism, a major complication of
nephrotic states.
Mechanistic Interpretation
Nephrotic syndromes cause urinary loss of
multiple plasma proteins, including:
• antithrombin III
• protein S
• plasminogen
, Loss of endogenous anticoagulants shifts
hemostasis toward a hypercoagulable state,
increasing risk for:
• renal vein thrombosis
• deep venous thrombosis
• pulmonary embolism
Why the Correct Answer Wins
Antithrombin III normally inhibits thrombin and
factor Xa. Urinary depletion removes a major
physiologic brake on coagulation.
This mechanism directly explains the patient’s
thrombotic complication.
Why the Distractors Fail
A. Increased hepatic synthesis of fibrinogen
Occurs secondarily in nephrotic syndrome but
