Plasma exchange combined with immunosuppressive drug therapy offers sustained benefits for chronic progressive multiple sclerosis patients. This extended study found significant long-term clinical improvement and no major life-threatening complications.

Area of Science:

  • Neurology
  • Immunology
  • Clinical Medicine

Background:

  • Previous studies indicated plasma exchange (PE) provides benefits for chronic progressive multiple sclerosis (CPMS) patients on immunosuppressive drug therapy (ISDT).
  • Further investigation is needed to assess long-term efficacy, retreatment criteria, and toxicity of combined PE and ISDT.

Purpose of the Study:

  • To evaluate the extended-term efficacy and safety of plasma exchange combined with low-dose immunosuppressive drug therapy in patients with chronic progressive multiple sclerosis.

Main Methods:

  • Analysis of 200 CPMS patients treated with PE and low-dose ISDT over seven years.
  • Assessment of clinical improvement using the Kurtzke Disability Status Scale.
  • Evaluation of long-term follow-up data up to six years.

Main Results:

  • Significant improvement in disability status was observed post-therapy and at 3-year follow-up compared to pre-treatment levels.
  • Clinical improvement was maintained in the majority of patients for up to 6 years.
  • No major life-threatening complications were attributed to the combined therapy.

Conclusions:

  • Combined plasma exchange and low-dose immunosuppressive drug therapy demonstrates sustained clinical efficacy in CPMS patients.
  • The treatment regimen appears safe for long-term use with no major adverse events observed.
