Parameters for monitoring treatment effects in CIDP with anti-MAG/SGPG IgM antibody

We used cycles of plasma exchange and intravenous cyclophosphamide to treat a patient who had chronic inflammatory demyelinating polyneuropathy with anti-myelin-associated glycoprotein/sulfoglucuronylparagloboside IgM antibody. After treatment, serum anti-sulfoglucuronylparagloboside IgM antibody titers were reduced significantly, and clear symptomatic improvement followed. The percentage of CD57-positive lymphocytes and natural killer cell activity had also returned to normal. Our findings indicate that serial measurements of these parameters are useful for monitoring treatment effect in this disease.
