Are individuals with severe haemophilia A prone to reduced bone density?

Individuals with severe haemophilia A may be at risk for reduced bone mineral density because of reduced weight-bearing exercise and hepatitis C infection. For confirming the reduced bone density, in the current cross-sectional study, we tried to address bone mineral density in individuals with severe haemophilia A and surveyed the relation of reduced bone density with hepatitis C viruses. To fulfil these aims, bone density and biochemical indexes in 18 individuals with severe haemophilia A and also in 18 individuals matched for age, sex, weight and height, as the control group, were examined. The obtained results showed that individuals with severe haemophilia A had reduced bone density (1.136 ± 0.118, 0.801 ± 0.238) in lumbar and femur regions, respectively, in comparison with the age- and sex-matched group (1.299 ± 0.237, 1.458 ± 0.505). The major complications of coagulation disorders are various types of excessive bleeding. The current study describes an association between severe haemophilia A and osteopenia, specifically at both the femur and the lumbar spine.
