Neuropathy of the phrenic nerve associated with antiganglioside antibodies.

Antiganglioside antibodies have been implicated in several autoimmune-mediated neuropathies, and binding of these antibodies can result in inflammatory changes of the nerves. Diaphragmatic paralysis is a rare condition, mostly arising from diseases affecting the phrenic nerve, neuromuscular junction, or skeletal muscle. In this case series, we identified five patients with diaphragmatic paralysis due to unilateral or bilateral neuropathy of the phrenic nerve associated with the presence of antiganglioside antibodies (immunoglobulin G anti-GT1a antibodies and immunoglobulin M anti-GM1 antibodies). The combination of an isolated phrenic nerve palsy with anti-GM1 antibodies has only once been described. On the other hand, the association of anti-GT1a antibodies with phrenic nerve palsy has never been reported before. We report an association between phrenic nerve palsy and the presence of antiganglioside antibodies, but it remains unclear if there is a causal relationship. Further studies are needed to explore this matter. © 2021 European Academy of Neurology.
