Efficacy of mycophenolate mofetil in patients with chronic immune demyelinating polyneuropathy

The authors retrospectively reviewed the efficacy of mycophenolate mofetil (MMF; mean dose, 2 g/day given for an average of 14 months) in 21 patients with immune demyelinating polyneuropathy. There were no significant differences in the median strength, sensory, or Rankin scores before and after treatment. In patients with immunoglobulin (Ig) M neuropathy, the M-protein decreased by 22%. Three patients with chronic inflammatory demyelinating polyneuropathy (30%) and one patient with IgM neuropathy (13%) improved. The authors found that MMF induced a modest benefit in similar to20% of their patients and stabilized patient condition, allowing reduction of steroid or IVIg therapy.
