Biomarkers in Autoimmune Disease of Nervous System

Death during the follow-up in every single reason

Brain or spinal MRI scans will be used to detect the presence of any autoimmune disease, including multiple sclerosis, neuromyelitis optica spectrum disorder, acute disseminated encephalomyelitis, autoimmune encephalitis, Guillain-Barré syndrome, and myasthenia gravis.

EDSS and its associated functional system (FS) score provide a system for quantifying disability and monitoring changes in the level of disability over time. EDSS is a scale for assessing neurologic impairment in multiple sclerosis (MS). It consists of 7 FS (visual FS, brainstem FS, pyramidal FS, cerebellar FS, sensory FS, bowel and bladder FS, and cerebral FS) which are used to derive EDSS score ranging from 0 (normal neurological exam) to 10 (death from MS). A negative change from baseline indicates improvement. A participant was considered to have a worsening in overall EDSS score of at least 2 if baseline EDSS score was 0, or at least 1 point if baseline EDSS score is 1 to 5, or at least 0.5 point if baseline EDSS score is 5.5 or more.

Modified Rankin Scale (mRS) is a profoundly valid and reliable measure of disability and is broadly utilized for assessing stroke outcomes and degree of disability. A favorable outcome was characterized as mRS ranging from zero up to two, while unfavorable outcome ranging for 3 up to 6.

Corrected visual acuity is determine by Snellen E chart held at a distance of 5 meters. Higher score indicates better vision.

Quantitative Myasthenia Gravis Score (QMG) range from 0 to 3. The normal person scored 0 and the higher score represent sever clinical symptom.

The MG-ADL is an eight-question survey of symptom severity, with each response graded from 0 (normal) to 3 (most severe). Two questions concern ocular, three oropharyngeal, one respiratory, and two extremity functions. Cumulative MG-ADL scores range from 0 to 24

The INCAT score comprises two parts, the arm score and the leg score. Based on a patient's level of impairment in their arms and legs, each part is scored between 0 and 5 points, resulting in an INCAT total score between 0 and 10.

The MRC score system for testing and grading of muscle function aims to provide a standardized and objective way to assess muscle function. It ranges from 0 to 5.

For MMT score, 16 muscle groups/ motions will be tested (not individual muscles). 14 of these are tested bilaterally. The score range from 0 to 10. A score of 10 is normal and a score of 0 is the worst.

SF-36 will used to understand the health related quality-of -life of the subjects after CT103A infusion. The eight health concepts: limitations in physical activities because of health problems; limitations in social activities because of physical or emotional problems; limitations in usual role activities because of physical health problems; bodily pain; general mental health (psychological distress and well-being); limitations in usual role activities because of emotional problems; vitality (energy and fatigue); and general health perceptions will be searched. These outcomes will be grouped as physical component summary and mental component summary. The norm data is 0-100, the health related quality of life is increases as the scores are increased. The average score is 50.

Health status is measured with the EuroQuality of Life Five Dimensions (EQ-5D) after CT103A infusion, which includes five dimensions and is used to evaluate the quality of life of sepsis survivors. They are mobility, self-care, usual activities, discomfort or pain and depression or anxiety. Levels are coded 1-5 and a total score is then generated. Results for the demographic measured will be displayed as a percentage value.

usual visual analog scale (VAS) of pain is used to evaluate pain after CT103A infusion (line from 0: no pain to 10:worst pain)

such as ferritin, CRP, IL-6 and procalcitonin) will be analyzed

Changes in immune cells (including proportion of CD3+ T cells, CD3+CD4+ T cells and CD3+CD8+ T cells, ratio of CD4+ T/CD8+T) in blood, CSF and other immune organs will be analyzed through flow cytometry and single cell sequencing.
