Brief Summary

Central nervous system (CNS) idiopathic inflammatory demyelinating diseases (IDD) are mainly diseases caused by autoimmune factors that result in CNS demyelination damage and loss. It tends to accumulate in the brain, spinal cord and optic nerves. Multiple sclerosis (MS), clinically isolated syndrome (CIS), neuromyelitis optica spectrum disorder (NMOSD), myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) and acute disseminated encephalomyelitis (ADEM) are all common IDDs of the CNS. Besides, primary angiitis of the central nervous system (PACNS), autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A), etc. may also be included because they are important differential diagnoses. This study will establish a large prospective cohort study database of Chinese IDD, which will record detailed electronic information on IDD patients, including demographic and socioeconomic data, medical history, clinical information, medication, and relevant examination results. The long-term observational study will be used to understand the natural history of disease, disability progression rates, imaging and biological indicators, long-term treatment approaches and prognosis of Chinese patients with IDD, to find predictive markers for IDD progression and prognosis, and to identify factors that influence the treatment and prognosis of patients with IDD.

Outcome Measures

Primary Outcomes (2)

  • Annual relapse rate (ARR) between baseline and follow-up in patients with IDD

    a new neurological worsening lasting for at least 24 hours and occurring more than 30 days after the previous attack.

    baseline up to 5 years

  • Change in EDSS scores of patients with IDD between baseline and follow-up over time

    The Expanded Disability Status Scale (EDSS) is a rating system that is frequently used for classifying and standardizing the severity and progression. EDSS ranges from 0 to 10. The higher the score, the worse the clinical symptoms.

    baseline, Month 6, Month12, Month18, Month24, Month30, Month36, Month42, Month48, Month54, Month60

Secondary Outcomes (12)

  • The brain structural change over time between the baseline MRI and the follow-up MRIs

    baseline, year1, year2, year3, year4, year5.

  • The spinal cord change over time between the baseline MRI and the follow-up MRIs.

    baseline, year1, year2, year3, year4, year5.

  • Change of the central vein sign at 7T MRI.

    baseline, year1, year2, year3, year4, year5.

  • Change of rim of iron at 7T MRI.

    baseline, year1, year2, year3, year4, year5.

  • Change in High-contrast Letter Acuity (HCLA) over time at baseline and during follow-up in patients with IDD

    baseline, year1, year2, year3, year4, year5.

  • +7 more secondary outcomes

Study Arms (4)

MS/CIS

Diagnosis of MS and CIS based on the 2017 McDonald MS diagnostic criteria.

Drug: Intravenous steroid

ADEM

Diagnosis of ADEM based on the 2012 IPMSSG diagnostic criteria for ADEM

Drug: Intravenous steroid

MOGAD

Diagnosis of MOGAD based on the 2020 Chinese Expert Consensus.

Interventions

This study does not limit treatment methods. Patients commonly use high-dose intravenous steroid therapy (HD-S) during acute stage. Immunomodulatory therapies are necessary for the remission stage. All drugs are used in accordance with relevant guidelines.
