Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators conduct this study to clarify the clinical features and to evaluate the prevalence of anti-nodal/paranodal antibodies of patients with combined central and peripheral demyelination (CCPD) .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators will review the clinical manifestation, laboratory test results, electrophysiological examination and neuroimaging findings of patients with CCPD. And we will detect antibodies to aquaporin 4(AQP4), myelin oligodendrocyte glycoprotein (MOG), neurofascin-155 (Nfasc155), neurofascin-186 (Nfasc186), and myelin-associated glycoprotein (MAG) in patients with CCPD.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients with CCPD

Inclusion criteria:

1. Criteria for central nervous system involvement: T2 high-signal intensity lesions in the brain, or spinal cord on MRI, or visual-evoked potentials(VEPs) abnormalities.
2. Criteria for peripheral nervous system involvement: conduction delay, conduction block, temporal dispersion or F-wave abnormalities, suggesting peripheral demyelinating neuropathy regarding nerve conduction studies (NCS). In the present study, it was compulsory for at least two nerves between the median, ulnar, tibial and peroneal nerves to have abnormal findings indicating demyelination.

Exclusion criterion:

Secondary demyelinating diseases or changes.

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. T2 high-signal intensity lesions in the brain or spinal cord on MRI, or visual-evoked potentials(VEPs) abnormalities.
2. conduction delay, conduction block, temporal dispersion or F-wave abnormalities, suggesting peripheral demyelinating neuropathy regarding nerve conduction studies (NCS).

Exclusion Criteria

1. infectious diseases(e.g., human T lymphocyte trophic virus type1-associated myelopathy, syphilis, neuroborreliosis, HIV infection or progressive multifocal leukoencephalopathy)
2. pre-existing inflammatory diseases (e.g., sarcoidosis, Behçet's disease, Sjögren's syndrome, vasculitis or other collagen diseases)
3. mitochondrial disease
4. metabolic/toxic diseases (e.g., vitamin deficiency, amyloidosis, chronic alcoholism, diabetes mellitus or subacute myelo-opticoneuropathy due to clioquinol intoxication
5. cervical spondylotic myelopathy
6. syringomyelia
7. spinocerebellar degeneration
8. multiple myeloma, other tumors
9. inherited diseases (e.g., leucodystrophies)
10. cerebrovascular disease
11. non-specific lesions on T2-weighted MRI (e.g., leucoaraiosis).
