title: Bone disease in patients with haemophilia A and B--where are we now?
abstract: It is evident that haemophilia A and B are associated with decreased bone mass in both adults and children. Decreased physical activity and vitamin D deficiency are some of the major factors leading to bone loss. Hepatitis C virus (HCV) infection may also contribute to low bone mineral density (BMD). However, definite conclusions regarding the exact prevalence and pathogenesis of osteoporosis cannot be conducted yet, due to the small sample size and significant heterogeneity among studies. Discordant findings with regard to the skeletal site of low BMD have also been reported. Furthermore, data on fracture risk are sparse. The use of the Fracture Risk Assessment Tool (FRAX) for assessing fracture risk, regular BMD assessment at the age of 25 and thereafter, careful evaluation of risk factors associated with bone loss and optimal calcium and vitamin D intake are recommended. Long-term prophylactic factor replacement therapy, resistance exercise and bisphosphonates, in severe cases of increased fracture risk, can prevent bone loss.
