The Therapeutic Effect of Betaine in Syringomyelia
- Registration Number
- NCT06308367
- Lead Sponsor
- Xuanwu Hospital, Beijing
- Brief Summary
Purpose: This clinical trial aims to evaluate the indications, therapeutic effects and side effects of betaine in refractory syringomyelia.
Primary outcome measure: The primary endpoint is the change of ASIA at week 12. The clinical efficacy is defined as ASIA increase ≥ 1 at week 12, as compared with that before betaine usage.
- Detailed Description
The pathogenesis of syringomyelia is poorly understood and duraplasty or shunting is not always effective. Although it is generally thought that syringomyelia is simply an accumulation of CSF from the subarachnoid space, the pathogenesis is likely to be more complex and may involve cellular and molecular processes.
The investigators supposed that betaine might play a key role in the pathogenesis of syringomyelia, especially post-traumatic syringomyelia(PTS), and that betaine, as an Osmotic homeostasis-related drug, would protect Osmotic homeostasis in syringomyelia.
Primary objectives: This clinical trial aims to evaluate the indications, therapeutic effects and safety of betaine in refractory syringomyelia.

Name Time Method ASIA Score 1 day before and 3 days, 3 months, after drug treatment American Spinal Injury Association(ASIA) Score for evaluating the spinal cord function， degree of the spinal cord function, motor1-100, sensory 1-224, higher scores mean a better outcome
- Secondary Outcome Measures
Name Time Method syringomyelia remission 1 day before and 3 days, 3 months, after drug treatment syringomyelia remission is defined as ≥ 25% reduction in syringomyelia volume on T2 images at week 12, as compared with that before thalidomide usage
Visual Analog Scale (VAS) 1 day before and 3 days, 3 months, after drug treatment degree of the pain, 1-10, higher scores mean a worse outcome
