Abstract

Background: Budd-Chiari Syndrome (BCS) is a life-threatening hepatic disorder caused by complete or partial obstruction of hepatic venous outflow. This study aimed to detect JAK2V617F mutation in Egyptian patients with BCS and its value in detection of occult Myeloproliferative Neoplasms (MPNs).
Material and Method: The study was carried out on 57 newly diagnosed BCS patients. Thrombophilia screening tests were performed in all patients including prothrombin G20210A mutation, Methyltetrahydrofolate Reductase (MTHFR) mutation, Factor V Leiden mutation, measurement of Antithrombin 3 (AT3), protein C functional activity, free protein S antigen, and antiphospholipid antibodies/lupus anticoagulant, in addition to detection of JAK2V617F mutation by real time polymerase chain reaction.
Results: In our study 35.1% of BCS patients had idiopathic etiology while 64.9% were secondary to other pro-thrombotic factors; the most common was MTHFR mutation (42.1%) followed by FV Leiden (29.8%) while JAK2V617F mutation was positive in 21.1% of cases, it was detected in 41.7% of patients with idiopathic BCS and in 58.3% with secondary pro-thrombotic factors with no significant relation between pro-thrombotic risk factors and JAK2V617F mutation (p= >0.005). JAK2V617F mutational screening in BCS had raised percentage of MPN as a cause for BCS from 15.8% to 24.6% when occult cases were added.
Conclusion: The JAK2V617F mutation is an acquired mutation associated with occult MPNs that can be used for diagnosis of latent MPNs presenting with thrombotic events.
