Neuromuscular complications of hematopoietic stem cell transplantation

Neuromuscular diseases such as polymyositis, dermatomyositis, peripheral neuropathy, and disorders of neuromuscular transmission are reported to be complications of hematopoietic stem cell transplantation (HSCT). Although cases have been reported with allogeneic HSCT in the setting of chronic graft versus host disease, they are also known to occur without evidence thereof and even occur in the setting of autologous HSCT. The 2005 National Institutes of Health Consensus Criteria classify polymyositis and dermatomyositis as “distinctive” features, and neuropathy and MG as “other” features. These neuromuscular complications present very similarly to the idiopathic autoimmune disorders and respond to similar treatment modalities. Muscle Nerve, 2015 Muscle Nerve 52: 480–487, 2015
