Hematopoietic stem cell transplantation (HSCT) for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP): Is it CIDP?

Abstract

Autologous hematopoietic stem cell transplantation (HSCT) is associated with 5-year treatment-free remissions in approximately 80% of patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) who failed or were dependent on intravenous immunoglobulin and or plasmapheresis. Autologous HSCT was associated with significant improvement in strength, independent ambulation, quality of life, nerve conduction velocity, and compound muscle action potential amplitude. The results of HSCT are dependent on proper patient selection, i.e., the right diagnosis and the right stage of the disease. An important caveat is that a significant number of patients with a CIDP diagnostic label are found upon further workup have a peripheral neuropathy of another etiology. Patients undergoing HSCT for CIDP should be reevaluated before HSCT to confirm the diagnosis and those who fail HSCT should be reevaluated for a diagnosis other than CIDP.
