RESUMO
In developed countries, the life expectancy of patients with hemophilia (PwH) is now close to that of the unaffected male population. This means that these patients are at risk of developing age-related comorbidities, including cardiovascular disease. Managing cardiovascular disease in PwH patients can be particularly challenging, due to their high bleeding risk. To our knowledge, this is the first report of a male patient with moderate hemophilia B and hypertensive ischemic heart disease complicated by arrhythmia due to nonvalvular atrial fibrillation, who was treated with apixaban and left atrial appendage closure while receiving concomitant anti-hemorrhagic prophylaxis with eftrenonacog alfa.
RESUMO
Ibrutinib is the first clinically approved inhibitor of Bruton's tyrosine kinase, an essential enzyme for survival and proliferation of B cells by activating the B-cell receptor-signalling pathway. Ibrutinib has been shown to be highly effective in B-cell malignancies and is recommended in current international guidelines as a first-line and/or second-line treatment of chronic lymphocytic leukemia. The drug has a favorable tolerability and safety profile but the occurrence of specific side effects (e.g. atrial fibrillation, bleeding and hypertension). If atrial fibrillation is diagnosed, anticoagulant therapy may be required. Such patients receiving concomitant anticoagulation should be followed closely. DOAC is preferred over a VKA because of the lower risk of major bleeding events and because of the favorable stroke risk--benefit profile. Of all, Dabigatran offers the availability of an antidote and shows reduced potential for CYP3A4 interactions. We report the cases relating to three patients in concomitant therapy with Ibrutinib and Dabigatran.
