Thrombosis in PNH ConclusionsThrombosis in PNH Conclusions

40-67% mortality in PNH results from thrombosis1

– Thrombosis is the leading cause of death in PNH2

– First TE increases risk for death 5 to 10-fold1

DVT or PE most common clinical presentation1

Arterial thromboses are also common1

Anticoagulant therapy may not be adequate to control thrombosis in PNH1

– Anticoagulant therapy also associated with higher risk of fatal hemorrhage in PNH4

Clinical thrombosis evident in PNH patients:1

– Minimal hemolysis

– No transfusion history

– Smaller clone size3
