This led us to look at existing thrombosis selleck products models in a new perspective. We have studied the effect of a FeCl3 induced arterial injury in both F8-KO and F9-KO mice using optimized conditions where exposure to FeCl3

induces occlusion within 4.2 ± 0.2 min in wild type mice with a normal coagulation system. In contrast, no occlusion was observed in haemophilic mice providing a therapeutic window in the model making it suitable for pharmacological testing of therapeutic intervention. We demonstrate that replacement therapy with a clinical relevant dose of rFVIII (Advate® 20–80 U kg−1) and rFIX [(0.75 mg kg−1 BeneFIX®) ∼50 IU kg−1] restored coagulation and normalized the time to occlusion following FeCl3 induced injury in F8-KO mice and restored coagulation and nearly normalized the time to occlusion in F9-KO mice. In conclusion, we have demonstrated that under optimized conditions the FeCl3 induced arterial injury Alvelestat mouse model provides a therapeutic window that makes it an useful effect model for evaluation of the haemostatic potential of procoagulant drugs. “

“Summary.  Central venous access devices (CVADs) are often required in children with haemophilia to secure venous access for prophylactic treatment or immune tolerance therapy.

Complications of CVADs include infections, thrombosis and mechanical problems. This study sought to determine the outcome of the vessels by magnetic resonance imaging (MRI) in children with haemophilia and to assess risk factors for development of catheter-related deep

venous thrombosis (DVT). After the removal of CVAD an MRI of the chest and neck was performed to 20 boys with haemophilia who each had 1–3 (total number 27) CVADs placed. MRI revealed DVT in five children (25%). As their CVADs were functional at the time of Nintedanib (BIBF 1120) the removal, the DVTs were clinically silent. However, there had been suspicion of DVT leading to replacement of the CVAD in one case. All the children with DVT had their CVADs inserted initially below the age of 1 year. The clinical signs of mild post-thrombotic syndrome (PTS) were common: dilated chest wall veins were observed in 11 (55%) children and were associated with DVT in three cases. Arm circumference discrepancy was observed in one child with DVT. No correlation between the duration or number of CVADs and DVT was detected. None of the patients had subjective symptoms of PTS. Silent DVT is a common complication of CVAD. Catheter insertion at a young age seems to predispose to thrombosis. The long-term consequences of the DVTs remain unknown. “
“Immune tolerance induction (ITI) can eliminate factor VIII (FVIII) inhibitory antibodies that appear during FVIII replacement therapy.
