Area of Science:

  • Neurology
  • Immunology
  • Biomedical Engineering

Background:

  • Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
  • Current treatments for MS aim to manage symptoms and slow disease progression, but novel therapeutic approaches are needed.

Purpose of the Study:

  • To evaluate the efficacy and safety of immunoadsorption membrane plasmapheresis (IAP) in patients with multiple sclerosis.
  • To assess the impact of IAP on immune cell activity and clinical outcomes in MS patients.

Main Methods:

  • Sixteen patients with multiple sclerosis underwent a structured IAP treatment protocol using polyvinyl alcohol gel columns.
  • Treatment involved varying frequencies of 3-liter plasma perfusions over an extended period.
  • Changes in natural killer (NK) cell and helper T cell activity were monitored.

Main Results:

  • IAP therapy significantly increased the activity of natural killer (NK) cells and helper T cells (p < 0.01).
  • All patients experienced improvements in muscle power.
  • Functional improvements were observed in walking, standing, sitting, and sensory and visual disturbances.

Conclusions:

  • Immunoadsorption membrane plasmapheresis (IAP) demonstrates significant therapeutic potential for multiple sclerosis.
  • IAP treatment is associated with enhanced immune cell function and notable clinical improvements in MS patients.
  • The procedure was well-tolerated, with no adverse effects reported, suggesting a favorable safety profile.
