We vaccinated a refractory essential monoclonal cryoglobulinemia patient with monocyte-derived DCs (Mo-DCs) pulsed with purified cryoglobulin as a tumor antigen. During the vaccinations, his acrocyanosis improved and we were able to reduce the number of hot baths used to treat his symptoms, with no side effects. Furthermore, cryoglobulin-specific proliferative responses were observed after the vaccination. As there was a recurrence of acrocyanosis after the final vaccination, vaccination with Mo-DCs pulsed with purified cryoglobulin would seem to be a useful treatment for refractory essential monoclonal cryoglobulinemia.
