Recurrent thromboembolism in a patient with beta-thalassemia major associated with double heterozygosity for factor V R506Q and prothrombin G20210A mutations.
Double heterozygosity for factor V R506Q and prothrombin G20210A mutations was identified in a 24-year-old man with beta-thalassemia major. The patient experienced a first thrombotic event at the age of 19 years and three recurrent thromboses in a short time interval, the third occurring while the patient was receiving long-term anticoagulant treatment. This case suggests that patients with major thalassemia and congenital thrombophilic mutations need intensive and long-lasting anticoagulant treatment. Thus, even if thrombotic events could be explained by a hypercoagulable state observed in patients with major thalassemia, after a first thrombotic event has occurred these patients should be screened for acquired and congenital thrombophilia.
