Autologous haematopoietic stem cell transplantation is an emerging treatment option in refractory chronic inflammatory demyelinating polyradiculoneuropathy. We describe a case of a 46-year-old male, with history of IgG/lambda monoclonal gammopathy, who was diagnosed with chronic inflammatory demyelinating polyradiculoneuropathy at 27 years of age. After an initial 10-year period of corticotherapy response, the patient experienced severe relapses and disease progression, evolving to a refractory state. First-line and escalating treatment could not achieve clinical stabilization, leading to severe disability. Pre-treatment with ibrutinib was initiated and autologous haematopoietic stem cell transplantation was performed without significant complications. Marked clinical improvement was observed in the following months, both subjective and objective. A significant proportion of the patients who respond to the first-line immunosuppressive therapy eventually become treatment-refractory. Autologous haematopoietic stem cell transplantation may be a treatment option, offering long-term remission with an overall acceptable side effect and risk profile.
