Subcutaneous immunoglobulin infusion: A new therapeutic option in chronic inflammatory demyelinating polyneuropathy

Intravenous application of immunoglobulins (IVIg) is an effective and usually well tolerated yet costly therapeutic regimen in chronic inflammatory demyelinating polyneuropathy (CIDP). We report two CIDP patients treated with subcutaneous infusion of immunoglobulins (SCIg) after IVIg therapy was shown to be effective. Application of SCIg was well tolerated, easy to manage, and led to stabilization of the disease course. SCIg may represent an effective new therapeutic option in CIDP and is associated with a cost reduction of at least 50% compared to IVIg therapy.
