Plasmapheresis decreases neuroelectric blocking activity in multiple sclerosis
Neurology
|August 1, 1982
Summary
Serum neuroelectric blocking factor activity decreased after plasmapheresis in multiple sclerosis (MS) patients but returned to baseline within weeks. No clear correlation was found between this activity and clinical improvement in MS.
Area of Science:
- Neuroimmunology
- Clinical Neurology
Background:
- Multiple Sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system.
- Neuroelectric blocking factors (NBFs) are implicated in MS pathogenesis.
- Plasmapheresis is a therapeutic apheresis technique used in various autoimmune conditions.
Observation:
- Seven patients with progressing MS symptoms underwent plasmapheresis.
- Five plasma exchanges of 2 liters each were performed over 10 days.
- Serum NBF activity was measured before and after treatment.
Findings:
- NBF activity decreased post-plasmapheresis in five of seven patients.
- NBF levels returned to baseline within 2-3 weeks in most patients.
- Clinical improvement was observed in only two patients, with no correlation to NBF levels.
Implications:
- Plasmapheresis transiently affects NBF activity in MS patients.
- The role of NBFs in MS progression and treatment response requires further investigation.
- Current findings do not support NBF activity as a reliable biomarker for plasmapheresis efficacy in MS.
