Sudomotor regulation failure in MS is associated with certain focal MS lesions.

MS is associated with an impairment in thermoregulatory sweating which seems to be related to the disease severity.

We report a patient presenting with myelitis after respiratory symptoms. A high level of antibodies to influenza A virus was measured in serum and cerebrospinal fluid (CSF), and the serum/CSF antibody ratio was 1.7, suggesting specific antibody production in the central nervous system. Magnetic resonance imaging of the spinal canal showed a contrast-enhanced swelling on the cervical medulla. Such a case would have warranted the use of antiviral therapy and calls to mind the neurotropic potential of influenza A viruses.

Our results enlarge the knowledge of autonomic disorders in ON patients, showing that sudomotor function may also be involved.
