Haemophilia patients experience acute pain during joint bleeds and chronic pain from haemophilic arthropathy. More than 50% of haemophilia patients have painful joints that cause disability and impair quality of life. Unfortunately, only a few clinical studies have investigated the non-pharmacological or pharmacological treatments for pain or the adverse effects of pain on the health and quality of life of children and adults with haemophilia. ⋯ A pain treatment protocol should include a definition of the problem of pain and best practices for physicians. A call to action is needed to standardize treatment approaches to pain and to develop algorithms/protocols for the management of pain in haemophilia patients. This review will highlight the prevalence and devastating impact of pain in haemophilia patients, currently available treatment options and identify the unmet needs for pain management.

Multicenter Study
von Willebrand factor/factor VIII concentrate (Humate-P) for management of elective surgery in adults and children with von Willebrand disease.
von Willebrand disease (VWD) is the most common inherited bleeding disorder. Treatment guidelines recommend the use of von Willebrand factor/factor VIII (VWF/FVIII) concentrate for VWD patients with type 2 or 3 VWD undergoing surgery, and type 1 patients undergoing surgery who are unresponsive, or for whom desmopressin acetate is contraindicated. This prospective, open-label, multinational study evaluated the safety, efficacy and optimal dosing of a VWF/FVIII concentrate (Humate-P) in subjects with VWD undergoing elective surgery. ⋯ Median VWF/FVIII concentrate loading doses ranged from 42.6 IU VWF:RCo kg(-1) (oral surgery) to 61.2 IU VWF:RCo kg(-1) (major surgery), with a median of 10 (range, 2-55) doses administered per subject. Adverse events considered possibly treatment-related (n = 6) were generally mild and of short duration. The results indicate that this VWF/FVIII concentrate is safe and effective in the prevention of excessive bleeding during and after surgery in individuals with VWD.
