Successful Treatment with Bortezomib for Refractory Thrombotic Thrombocytopenic Purpura Associated with Systemic Lupus Erythematosus.

Thrombotic thrombocytopenic purpura (TTP) is a life- threatening disease that can be secondary to systemic lupus erythematosus (SLE). The fist- line treatments of TTP are steroid, immunosuppressor and plasm exchange (PE). However, some patients may have a poor response to these treatments. Bortezomib is a selective proteasome inhibitor and widely used to treat patients with multiple myeloma (MM). In recent years, bortezomib has been used to treat patients with refractory TTP. Here we report a patient with refractory TTP associated with SLE and had a successful treatment with bortezomib.
