Progressive muscle weakness after high-dose steroids in two children with CIDP

Abstract

Corticosteroids and intravenous immunoglobulins belong to the first line of treatment in chronic inflammatory demyelinating polyneuropathy. In patients with a progressive course, plasma exchange and immunomodulatory drugs are added to the regimen. To reduce the side effects of long-term oral prednisolone, high-dose pulsatile intravenous methylprednisolone treatment has been advocated. We report two children with chronic inflammatory demyelinating polyneuropathy who, after high-dose intravenous pulsatile methylprednisolone, experienced a significant clinical deterioration with profound loss of muscle strength. Both patients improved after changing treatment to immunoglobulins in one and cyclosporine combined with immunoglobulins and oral prednisolone in the other.
