chondroitin-sulfates and Gastrointestinal-Hemorrhage

In a randomised cross-over study we assessed total blood loss in 14 dialysis patients using 59Fe as a marker for measurement in a whole-body counting system. In one period the patients received standard heparin, in the other ORG 10172, a new low-molecular-weight-heparinoid. Our results show no significant difference between the two study periods with regard to blood loss and dialyser blood retention. In some patients a delayed bleeding ('oozing') from the puncture site was noticed as a side-effect of treatment with the low-molecular-weight-heparinoid. We conclude that this heparinoid is effective as an anticoagulant in regular dialysis treatment, but it seems to have no advantage over standard heparinisation with regard to occult bleeding. This may be related to the prolonged plasma anti-Xa activity (30.8 h) of this compound compared to standard heparin in dialysis patients.

A 54-year-old man had been admitted to Nara city hospital because of hematemesis and dyspnea caused by physical exertion, and was given a diagnosis of esophago-cardial varices and portal venous thrombosis. He was transferred to our hospital for further examinations and treatments. Ultrasonography (US) and computed tomography (CT) revealed the progression of portal venous thrombosis. Danaparoid sodium was administered to treat the portal vein thrombus. 5 days later, the patient was found to have hematemesis resulting from a cardial varices rupture. After endoscopic variceal ligation (EVL) and endoscopic injection sclerotherapy (EIS) was performed, danaparoid sodium was administered for 2 weeks. After the treatment, portal vein thrombus had almost disappeared. Due to an increased risk of bleeding, cases of esophago-cardial varices with portal venous thrombosis must be treated with care. This is the first report of upper gastrointestinal bleeding due to danaparoid sodium. Danaparoid sodium must be carefully administered when patients have portal venous thrombosis with delicate varices.
