[Indication of autologous stem cell transplantation in chronic inflammatory demyelinating polyneuropathy: Guidelines from the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)]

Abstract

Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is a chronic autoimmune disease involving the peripheral nervous system, characterized by focal and segmental demyelination accounting for neurological deficit. CIDP diagnosis is based on several criteria and requires the presence of specific clinical symptoms and of demyelinating criteria on the electroneuromyogram (ENMG) or of additional supportive criteria (spinal fluid examination with dissociation between albumin level and cellular abnormalities, nervous abnormalities on MRI or other minor abnormalities on ENMG, demyelinating features on nerve biopsy or patient improvement under so-called first-line therapy with immunodulator treatment). After failure of two successive first line immunomodulating drug therapies (corticosteroids, immunomodulating immunoglobulins, or plasma exchange), several options can be considered as second line therapies. The efficacy of autologous hematopoietic cell transplantation (AHCT) has been shown in CIDP patients. The aim of these recommendations established by a working group of experts from the "Société française de greffe de moelle osseuse et thérapie cellulaire (SFGM-TC)", the group "maladies auto-immunes et thérapie cellulaire (MATHEC)" and the "filière de santé maladies rares neuromusculaire (FILNEMUS)" is to specify the eligibility criteria for AHCT in CIPD patients, to describe the mobilization and the conditioning regimen for the AHCT procedure, as well as the patient standardized post-transplant follow-up and the management of neurological treatment throughout the all procedure.
