[High-dose intravenous immunoglobulin treatment in chronic inflammatory demyelinating polyneuropathy].
We treated two patients with chronic inflammatory demyelinating polyneuropathy (CIDP) with high-dose intravenous immunoglobulin (HIG). The patients received 400 mg/kg of immunoglobulin a day for five days. One patient, who had failed to respond to prednisolone before, was treated with HIG, 18 months after the onset. His motor symptoms resolved immediately after the commencement of HIG. Electrophysiologically, the compound muscle action potentials increased in amplitude in all nerves examined and F wave reappeared in the left median nerve. The electrophysiological changes were compatible with improvement of conduction blocks. This patient had headache and exanthema during the HIG therapy, but they settled after cessation of the infusion. The other patient was administered HIG as an initial treatment, four months after the onset. HIG was of no effect in this case, but he showed remarkable recovery during the following prednisolone therapy. Although corticosteroid therapy is the first choice for CIDP, there are CIDP patients who do not respond to steroid or can not complete the steroid therapy because of adverse effects. HIG is an expectative and recommendable treatment for the steroid resistant CIDP patients.
