[Pathogenesis and management of hemorrhage and thrombosis in plasma cell dyscrasias].
Unexpectedly high rates of venous thromboembolic events (VTE) induced by highly effective immune modulating drugs thalidomide and lenalidomide for treatment of multiple myeloma have focused attention on the incidence and underlying pathophysiology of VTE in patients with plasma cell dyscrasias, and on thromboprophylaxis approaches. While bleeding complications are relatively uncommon in the patients with lymphoproliferative disorders, acquired von Willebrand syndrome, typically occurring in the patients with monoclonal gammopathy of unknown significance, and acquired coagulopathies associated with primary amyloidosis can present with haemorrhagic complications and both are challenges to the management. This review highlights these important haemostasis-related complications of plasma cell dyscrasias and provides an overview of other uncommon bleeding and thrombotic events that can affect diagnosis and therapeutic management of clonal plasma cell disorders. Due to the infrequency of most these haemostasis complications, available information is typically based on retrospective cases or series analysis.
