A Study on the Safety of Liver Biopsy Inpatients with Von Willebrand’s Disease

چکیده
Objectives: Liver biopsy remains the gold standard for diagnosis of chronic liver diseases. Outpatient percutaneous biopsy is generally safe with a mortality rate of 0.17% and hospitalization rate for bleeding of 3%. Von Willebrand disease (vWD) syndrome is the most common inherited hematological disorder with a prevalence of 1% 3% globally. We sought to study whether vWD increases the risk of bleeding for liver biopsies. Methods: All patients (n = 120) who underwent outpatient percutaneous liver biopsies from 1997 to 2007 were analyzed. Demographics, PT/INR, platelet count, vW antigen and ristocetin induced platelet aggregation were studied. Results: No vWD patients had major bleeding that required transfusion, hospitalization or surgery but 9 (75%) had minor local bleeding and all had ecchymosis, which resolved spontaneously within 24 hours. Conclusions: Patients with vW factor deficiency can undergo percutaneous liver biopsy without major bleeding. Minor bleeding may occur at a slightly higher rate. vWD is not a contraindication to percutaneous liver biopsy.

Up to 30% of Iranian adult multi-transfused thalassemic patients are infected with hepatitis C virus (HCV) which can intensify the progression of liver disease caused by iron overload in this group of patients. Our aim was to assess the biochemical and virological response of interferon alfa (INF-α) and its safety in thalassemic patients with chronic HCV infection. This trial was a single c...
