Popis: | Objectives Bortezomib is a proteasome inhibitor that is frequently used for multiple myeloma and lymphoma. A sensory predominant axonal neuropathy is associated with bortezomib treatment but a demyelinating neuropathy is also described primarily based on electrodiagnostic findings. We report a series of patients treated with bortezomib who developed peripheral neuropathy and were found to have demyelinating features on electrodiagnostic testing. Methods Four patients who developed a bortezomib-induced peripheral neuropathy underwent electrophysiological testing, and 1 patient had a nerve biopsy. Results The four patients with bortezomib-induced peripheral neuropathy had demyelinating features on their electrophysiological testing. The nerve biopsy performed in 1 patient demonstrated a demyelinating component in a background of axonal degeneration. Conclusions Although most toxic neuropathies are symmetrical axonal neuropathies, bortezomib is part of a small list of agents that may cause a demyelinating polyneuropathy and axonal degeneration. These findings have been confirmed by nerve biopsy. |
