The use of anticoagulant therapy in individuals with atrial fibrillation is very effective at reducing the risk of stroke but risk stratification models have not been applied to or validated for haemophilia. It is not clear to what

extent haemophilia may protect against stroke and there are major practical issues in considering anticoagulant therapy selleck products in these individuals. Reports of thrombotic stroke in haemophilia are rare but this may be in part because there are so few older patients in the highest risk stratum. Cancer is another major cause of morbidity and mortality in the general population. It is estimated that one in three individuals develop cancer during their lives and the risk for many cancers is age related [31]. There are two key issues for pwh: is the risk of cancer increased in haemophilia, and is the management of cancer more problematic in individuals with bleeding disorders? The two situations where mortality is clearly increased

are in those infected with HIV or HCV. The incidence of non-Hodgkins lymphoma, basal cell cancer and Kaposi sarcoma has been shown to be increased in HIV-infected individuals with haemophilia compared with non-infected pwh MLN0128 research buy [32]. Since the introduction of HAART, the incidence and mortality in this group of individuals has declined [33], but there are few recent data as to whether advancing age may yet change this pattern. The risk of hepatocellular carcinoma (HCC) is increased in chronic HCV infection and this is reflected in the fact that HCC is now a leading cause of death in pwh [34]. Furthermore, the risk of HCC is increased in older age [35]. There are conflicting data on the incidence of cancer in haemophilia in pwh without HIV and HCV. Many of the studies reporting on this

had several potential sources of error and mortality rates in the study populations were high from viral infections and bleeding and thus these individuals may not have lived long enough to develop cancer. A Dutch study looking at mortality in pwh in the period MCE公司 1973 – 1986 found an excess of deaths from cancer, particularly lung cancer [9] and a small, more recent German study [36] found an almost four fold increase in extra hepatic malignancy in their study group. This contrasts with several other studies that found no significant increase in malignancy in non-HIV and non-HCV-infected individuals with haemophilia [4,6,11,37,38]. These conflicting data again highlight the need for larger, prospective studies. By virtue of advancing age, it is likely that more individuals with cancer will be encountered in clinical practice. Factor replacement therapy will clearly be necessary to cover diagnostic procedures such as biopsy or surgical procedures and should be relatively straightforward. However, there are few data to guide replacement therapy to prevent bleeding from tumours that shrink with chemotherapy or radiotherapy.
