BACKGROUND Septic shock is frequently complicated by a syndrome of disseminated intravascular coagulation (DIC). Numerous uncontrolled clinical studies have reported that antithrombin III (ATIII) substitution might prevent DIC and death in septic shock. METHODS We conducted a randomized double-blind placebo-controlled trial in patients with a documented(More)
STUDY OBJECTIVE Our aim was to document the following in patients with septic shock and disseminated intravascular coagulation (DIC): (1) the influence of DIC in the mortality rate and the occurrence of organ failure; (2) the comparative prognostic value of initial antithrombin III (ATIII), protein C (PC), and protein S (PS) levels; and (3) the compared(More)
PURPOSE Diagnosis and quantification of hepatic fibrosis are especially important in patients with chronic liver disease. Liver biopsy remains the gold standard for diagnosis of cirrhosis but has several limitations. The purpose of this study was to determine the usefulness of diffusion-weighted MR imaging, for the diagnosis of cirrhosis and quantification(More)
BACKGROUND/AIMS Evaluation of the degree of hepatic fibrosis is especially important in patients with chronic liver disease. Our aim was to study the diagnostic accuracy of abdominal ultrasonography for cirrhosis or fibrosis. METHODS Twenty-three clinical (n=12) and Doppler ultrasonic (n=11) variables were recorded in 243 patients with chronic (alcoholic(More)
This study was carried out to assess the clinical efficacy in von Willebrand's disease (vWD) of a new, very high purity (VHP), solvent/detergent (SD)-treated, vWF concentrate (VHP Human von Willebrand Factor Concentrate, Biotransfusion) characterized by a high specific ristocetin cofactor (vWF:RCo) activity and a low factor VIII (FVIII) coagulant activity(More)
The clinical and laboratory features of 100 patients with lupus anticoagulant (LA) are reviewed. Subjects were divided into three groups according to their age (1-5, 15-35, 45-89 years). Female prevalence was observed in each group and overall F/M ratio was 3/1. An underlying autoimmune disease (principally lupus erythematosus) was found in 47 cases (10% of(More)
Solvent-detergent (S/D) viral inactivation was recently adapted to the treatment of single plasma donations and cryoprecipitate minipools. We present here a new process and a new bag system where the S/D reagents are removed by filtration and the final products subjected to bacterial (0.2 microm) filtration. Recovered and apheresis plasma for transfusion(More)
Some lupus anticoagulants (LA) have been shown to be directed against phospholipid-bound prothrombin. While developing an ELISA to detect anti-prothrombin autoantibodies in patient serum or plasma, no or very low signal was observed using human prothrombin immobilized on plain polystyrene plates. In contrast, the same LA-positive samples bound specifically(More)
An acquired von Willebrand's disease developed in two patients in association with a monoclonal gammopathy plus a Sjögren's syndrome and a chronic lymphocytic leukaemia (CLL). In both cases a plasma inhibitor to von Willebrand factor (vWf) was suspected and characterized after plasma gel filtration. The inhibitor was shown to be entirely complexed with vWf(More)
The pathophysiology of acquired von Willebrand syndrome (AVWS), a rare bleeding disorder, is not fully understood. Circulating antibodies to Von Willebrand factor (VWF) are found in patients with AVWS associated with lymphoproliferative disorders but these autoantibodies are difficult to detect with routine laboratory tests and neutralisation assays. We(More)
