Plasma Exchange for MG

Map a Treatment Plan for a Fast Road to Results

Seeing results as quickly as possible is critical in order to hasten recovery or maintain optimal symptom management.

Plasma exchange rapidly reduces disease mediators, essentially quieting the immune response and relieving symptoms.1 For MG crisis, this may mean hastening recovery, such as enabling the patient to come off the ventilator faster and achieve quicker functional outcome improvement.1,2,3

Plasma Exchange Treatment for Myasthenia Gravis (MG)
Hear from Dr. Demeret as she shares her extensive experience in using TPE to treat MG.


"Although clinical trials suggest that intravenous immunoglobulin (IVIg) and plasma exchange are equally effective in the treatment of impending or manifest myasthenic crisis, expert consensus suggests that plasma exchange is more effective and works more quickly." 3

Time to Clinical Effect of Therapies for MG1

Treatment Time to Clinical Effect
Pyridostigmine 10–15 minutes
Plasma exchange 1–14 days
IVIg 1–4 weeks
Prednisone 2–8 weeks
Mycophenolate mofetil 2–6 months
Cyclosporine 2–6 months
Azathaioprine 3–18 months

Speed to Recovery for MG and MuSK+ MG Patients

Studies show therapeutic plasma exchange (TPE) provides significant clinical benefits when used as a stand-alone therapy for MG patients, including those with moderate-severe generalized, refractory, crisis and muscle-specific tyrosine kinase MG (MuSK+ MG). TPE has been shown to be effective for the majority of patients in these groups—not all patients respond the same to therapy. 3,4,5,6
MG Results Using Plasma Exchange in Addition to Standard of Care


A REDUCTION IN DISEASE SEVERITY BY 2 GRADES
experienced by 89% of 18 patients 7


IMPROVEMENTS IN THE MG DISEASE SCALE
shown in 78.7% of 33 patients 8


AN IMPROVEMENT IN FUNCTIONAL GRADING FROM A MEDIAN OF 4 TO 1 9
experienced in 100% of 11 patients


FULL RECOVERY FROM MG CRISIS
in 81% of 16 patients 10





MuSK+ MG Results
Multiple studies and expert opinions support that plasma exchange has superior efficacy over IVIg for MuSK+ MG.1,3,5,11,12

Retrospective chart review of 53 MuSK+ MG patients at nine university-based centers in the U.S. showed that 51 percent of patients improved with plasma exchange versus 20 percent with IVIg.12
In a 2011 review of 110 MuSK+ MG patients from two large clinics in Italy and the U.S., plasma exchange produced improvement in 93 percent of patients, compared with 61 percent who improved after IVIg. Clinical improvement was determined by a treating physician.11






Plasma Exchange as First-Line Therapy for MG

The Spectra Optia® Apheresis System is the first therapeutic apheresis system indicated to treat MG. Plasma exchange is recommended as first-line therapy by the American Society for Apheresis (ASFA), the European Federation of Neurological Societies (EFNS), the German Neurological Society (GNS) and the Myasthenia Gravis Foundation of America (MGFA) for acute/crisis and refractory myasthenia gravis and pre-thymectomy.



Evidence-Based Guidelines for Plasma Exchange in MG
European Federation of Neurological Societies (EFNS) 201013
  • Acute exacerbation (Level A)
  • Pre-thymectomy (Level B)
American Society for Apheresis (ASFA) 20166
  • Moderate-severe Category I (Grade 1B)
  • Pre-thymectomy Category I (Grade 1C)
Myasthenia Gravis Foundation of America (MGFA) Consensus 20163
  • Short-term treatment in myasthenic crisis
  • Pre-thymectomy
  • Refractory MG
  • Prior to corticosteroids
German Neurological Society (GNS) 201614
  • Myasthenic crisis—Category I








Interested in Plasma Exchange for GBS?
Using plasma exchange on Spectra Optia results in a fast road to recovery for the majority of GBS patients by delivering a rapid clinical response.











Apheresis-Related Safety Information

Contraindications

Leukocytapheresis is contraindicated in acute myeloid leukemia FAB M3 (acute promyelocytic leukemia) because of the accompanying disseminated intravascular coagulation.1,2  Other contraindications for the use of the Spectra Optia system are limited to those associated with the infusion of solutions and replacement fluids as required by the apheresis procedure and those associated with all types of automated apheresis systems.

Adverse events of apheresis procedures can include

Anxiety, headache, light-headedness, digital and/or facial paresthesia, fever, chills, hematoma, hyperventilation, nausea and vomiting, syncope (fainting), urticaria, hypotension, allergic reactions, infection, hemolysis, thrombosis in patient and device, hypocalcemia, hypokalemia, thrombocytopenia, hypoalbuminemia, anemia, coagulopathy, fatigue, hypomagnesemia, hypogammaglobulinemia, adverse tissue reaction, device failure/disposable set failure, air embolism, blood loss/anemia, electrical shock, fluid imbalance and inadequate separation of blood components.

Reactions to blood products transfused during procedures can include

Hemolytic transfusion reaction, immune-mediated platelet destruction, fever, allergic reactions, anaphylaxis, transfusion-related acute lung injury (TRALI), alloimmunization, posttransfusion purpura (PTP), transfusion-associated graft-versus-host disease (TA-GVHD), circulatory overload, hypothermia, metabolic complications and transmission of infectious diseases and bacteria.3,4

Restricted to prescription use only

  • Operators must be familiar with the system's operating instructions.
  • Procedures must be performed by qualified medical personnel.
