The disorder may be genetic, acquired, and often in the acquired cases autoimmune. This chapter focuses on autoimmune acquired causes. Autoimmune associations include mainly contactin-associated protein-like 2 (CASPR2) antibody-associated disease (previously termed as VGKC or voltage-gated potassium channel antibody-associated neuromyotonia) (van Sonderen et al., 2016, p. 2), leucine-rich glioma-inactivated 1 (LGI1) antibody disease, the Guillain-Barré syndrome, NMDAR encephalitis (Varley et al., 2019), and IgLON5 (Gaig et al., 2021) disease. Nonimmune associations include radiation-induced plexopathy. An association with myasthenia gravis and other autoimmune disorders, response to plasma exchange (Newsom-Davis and Mills, 1993) and physiologically induced changes in mice injected with patient-derived immunoglobulins led to the discovery of autoantibodies to juxtaparanodal proteins complexed with potassium channels (Shillito et al., 1995). The target of the antibodies is most commonly the CASPR2 protein. The disorder may be paraneoplastic, and a search for and treatment of an underlying tumor is a necessary step.

Its therapeutic effect in MS relies on various mechanisms: (1) the immunosuppressive conditioning regimen prior to aHSCT was able to eradicate the autoreactive cells and (2) the regeneration/renewal of the immune system to reset the aberrant immune response against self-antigens. The aHSCT procedure includes the following different steps, as described in this chapter: patient selection through careful pretransplant screening, \"wash-out\" period from previous treatments, mobilization of hematopoietic stem cells (HSC), conditioning regimen, HSC infusion, and posttransplant monitoring for early and late complications. Moreover, specific aspects of pediatric population undergoing aHSCT are described. According to the available evidence, aHSCT appears to be safe in pediatric MS, obtaining disease control for a prolonged time after the procedure. A reasonable approach in this setting includes the application of less toxic treatments while reserving aHSCT procedure for patients with severe/refractory forms of the disease.

Paraneoplastic neuropathies account for a small but high morbidity and mortality subgroup. Symptoms include weakness, sensory loss, sweating irregularity, blood pressure instability, severe constipation, and neuropathic pain. Neuropathy is the first presenting symptom of malignancy among many patients. The molecular and cellular oncogenic immune targets reside within cell bodies, axons, cytoplasms, or surface membranes of neural tissues. A more favorable immune treatment outcome occurs in those where the targets reside on the cell surface. Patients with antibodies binding cell surface antigens commonly have neural hyperexcitability with pain, cramps, fasciculations, and hyperhidrotic attacks (CASPR2, LGI1, and others). The antigenic targets are also commonly expressed in the central nervous system, with presenting symptoms being myelopathy, encephalopathy, and seizures with neuropathy, often masked. Pain and autonomic components typically relate to small nerve fiber involvement (nociceptive, adrenergic, enteric, and sudomotor), sometimes without nerve fiber loss but rather hyperexcitability. The specific antibodies discovered help direct cancer investigations. Among the primary axonal paraneoplastic neuropathies, pathognomonic clinical features do not exist, and testing for multiple antibodies simultaneously provides the best sensitivity in testing (AGNA1-SOX1; amphiphysin; ANNA-1-HU; ANNA-3-DACH1; CASPR2; CRMP5; LGI1; PCA2-MAP1B, and others).
