Outcomes

Primary Outcome Measures

change in disease specific antibody titers after application of Bortezomib
Change in disease specific antibody titers (anti-ACh for myasthenia gravis, anti-dsDNA for systemic lupus erythematosus, anti-ACPA for rheumatoid arthritis) 6 months after end of Bortezomib therapy (duration 6 weeks) compared to baseline (before therapy).

change in dose of immunosuppressive co-medication
Change in titers of protective antibodies (e.g. measles)
Change in titers of protective antibodies against measles virus, rubella virus, varicella zoster virus, pneumococcus, cytomegalovirus
Change in number of antibody producing plasmablasts/cells
Change in number of antibody producing plasmablasts/cells in peripheral blood
Change in concentration of soluble mediators (e.g. IL-6)
Change in concentration of soluble mediators (e.g. IL-6) in peripheral blood
need for hospitalisation

5. Study Description

Brief Summary
The aim of this pilot study is to investigate the application of proteasome inhibitor Bortezomib (Velcade®, approved for therapy of multiple myeloma) in patients with therapy-refractory antibody-mediated autoimmune diseases. The investigators hypothesis is that the proteasome inhibition will lead to reduced antibody titers and improved clinical outcome.
