Neuropathy associated with IgM paraproteinemia

(See separate entry for Axonal neuropathy associated with IgM paraproteinemia)

RecommendationsDemyelinating neuropathy associated with IgM paraproteinemia, without anti-MAG antibodies
IVIG is recommended for neuropathy associated with IgM, with clinical and electrophysiological features consistent with CIDP, in the absence of anti-MAG antibodies.
Dose/Frequency of Administration2 g/kg adjusted body weight divided over 2 to 5 days, every 4 weeks.

IVIG should be administered for 3 to 6 months to assess efficacy. Some patients do not show a definitive sustained response until they have undergone up to 6 treatment cycles.

Once the patient’s condition has stabilized, consider titrating the dose and/or the treatment interval to the lowest dose necessary to maintain clinical effectiveness.
