This phase II/III open-label, multicentre study evaluated the efficacy and safety of BIOSTATE®, a high purity plasma-derived double-virus inactivated FVIII/VWF concentrate, when used in non-surgical bleeds, surgical procedures and prophylactic therapy in VWD patients for whom desmopressin treatment was deemed ineffective, inadequate or contraindicated. Twenty three patients (7 type 1, 9 type 2 and 7 type 3; 12 male, 11 female), who received FVIII/VWF concentrate as part of their VWD management, were recruited prospectively between December 2004 and May 2007 from eight centres in Australia

and New Zealand. find protocol BIOSTATE dosing was based on pre-treatment FVIII:C and/or VWF:RCo plasma levels and a predetermined dosing guide. Haemostatic efficacy of BIOSTATE was rated as excellent or good for all major and minor surgery events, long-term prophylaxis, and for four of the six assessable non-surgical bleeding events. Blood transfusions were required by two major surgery patients as well as one patient with a non-surgical bleed. The median overall exposure to BIOSTATE across all groups

was 8 days, greater in the prophylactic group (range 53–197) compared with major surgery (3–24), minor surgery (1–8) and non-surgical bleeds Trichostatin A solubility dmso (1–10). BIOSTATE was shown to be efficacious and well tolerated when treating patients with VWD. This study also provides Cyclin-dependent kinase 3 important insights into dosing regimens with BIOSTATE and the role of monitoring therapy with FVIII:C and VWF:RCo. “
“Recurrent bleeding into joints initiates a sequence of events leading to a progressive joint damage in people with severe haemophilia. This is a continuous process during childhood and adolescence,

therefore joint abnormalities may be minimal on physical examination in very young children – even those receiving on-demand treatment. The aim of our study was to quantify the burden of arthropathy in Lithuanian patients who had been treated exclusively by on-demand substitution and compare their physical joint health with age-matched Danish patients who received prophylaxis from an early age. Boys, aged 4–17 years, with severe haemophilia and no signs of inhibitors were included in the study. Joint outcome based on the Haemophilia Joint Health Score (HJHS) was analysed in two different treatment groups and compared within the matched pairs. In total, 32 (16 in each treatment group) patients were enroled. A total of 192 joints were evaluated. Joint status according to treatment strategy was strikingly different: 27.4 for on-demand vs. 3.3 for prophylaxis (<0.001) group. Significance of the difference in joint status comparing different treatment strategies was equally strong both in younger (4–9 years) and older (10–17 years) patient groups: 2.2 vs. 12.5 (P = 0.0002) and 3.9 vs. 36.3 (P < 0.0001) respectively.
