The risk of variceal bleeding in cirrhotics is associated with increasing liver dysfunction, larger varices, endoscopic red signs, and higher portal pressure. However, why bleeding occurs unpredictably and infrequently in individual patients is unknown.
Bacterial infections occur in 35–66% of cirrhotics presenting with gastrointestinal bleeding.1 We proposed a possible pathophysiological basis linking infection and variceal bleeding via endotoxin induced endothelin release and subsequent portal pressure rise, combined with impaired platelet aggregation due to endotoxin induced nitric oxide and prostacyclin.2 Infected cirrhotics demonstrate a heparin effect using heparinase I modified thromboelastography (TEG) and have anti-Xa activity.3,4 Now we show similar findings in two cirrhotics during the course of acute variceal bleeding.
Patient 1 was male, 66 years old (Child-Pugh grade C), and patient 2 was female, 42 years old …
