Overview. Plasmapheresis or — plasma exchange — is a process involving the following steps: Whole blood is withdrawn from a large vein. A machine separates the liquid portion of blood (plasma) from the red and white blood cells. The cells are transfused back along with a plasma replacement fluid. This exchange, sometimes referred to as a “blood-cleansing procedure,” is a …
What is the purpose of plasmapheresis in the treatment of?
A: Plasmapheresis is used as a second-line therapy (after systemic corticosteroids) in the management of multiple sclerosis (MS) relapses (or “attacks”) and other central nervous system (CNS) demyelinating diseases including acute disseminated encephalomyelitis, idiopathic transverse myelitis, idiopathic optic neuritis ...
What is the purpose of plasmapheresis in clients with GBS?
Plasma exchange removes antibodies and other potentially injurious factors from the blood stream. It involves connecting the patient's blood circulation to a machine which exchanges the plasma for a substitute solution, usually albumin. Several studies have evaluated plasma exchange for Guillain-Barré syndrome.
What is the goal of therapeutic apheresis?
Therapeutic apheresis (TA) is an extracorporeal treatment that selectively removes abnormal cells or substances in the blood that are associated with or cause certain disease states. It can also be used to administer cells or plasma constituents that are present in subtherapeutic concentrations.Feb 18, 2022
What diseases are treated with plasmapheresis?
Today, plasmapheresis is widely accepted for the treatment of severe myasthenia gravis, Lambert-Eaton syndrome, Guillain-Barré syndrome and chronic demyelinating polyneuropathy. Its effectiveness, however, in other conditions such as multiple sclerosis, polymyositis and dermatomyositis, is still being studied.May 8, 2020

What is the difference between IVIG and plasmapheresis?
Intravenous immunoglobulin (IVIG) is a biological agent obtained through the fractionation of blood from 2000–16,000 patients. Plasma exchange (PLEX) is a blood separation technique thought to remove autoantibodies. Both IVIG and PLEX have been found to be effective disease stabilizing therapies for patients with MGC.
What is plasmapheresis dialysis?
Plasmapheresis is similar to dialysis; however, it removes the plasma portion of the blood where the antibodies are located. Plasma is the almost clear part of the blood which carries red cells, white cells, platelets and other substances through your bloodstream.
How does plasmapheresis work for myasthenia gravis?
How plasmapheresis helps myasthenia gravis patients. Myasthenia gravis is a rare chronic disease caused by patients' own antibodies attacking healthy tissues in the body. Plasmapheresis helps relieve the symptoms of the disease by filtering out the antibodies from the plasma.
What type of catheter is used for plasmapheresis?
Patients require either a double-lumen central venous catheter or two large-bore antecubital peripheral lines. Plasmapheresis can be performed using a semipermeable membrane–based device in combination with hemodialysis equipment.Mar 8, 2021
Why is plasmapheresis considered a successful treatment for patients with autoimmune disorders?
Plasmapheresis treats autoimmune diseases, toxins in the blood, neurological diseases, and very high levels of cholesterol that don't lower with medications or dietary changes. Plasmapheresis removes antibodies against the person's own body cells and tissues (autoantibodies) from the blood.Jan 28, 2021
Does plasmapheresis remove good antibodies?
Plasmapheresis is a process that filters the blood and removes harmful antibodies. It is a procedure done similarly to dialysis; however, it specifically removes antibodies from the plasma portion of the blood.
What is the difference between plasma exchange and plasmapheresis?
Plasmapheresis refers to a procedure in which the plasma is separated from the blood either by centrifugation or membrane filtration. Once separated the plasma can be manipulated in a variety of ways. Plasma exchange refers to discarding the plasma totally and substituting a replacement fluid.
What is plasmapheresis in medical terms?
A: Plasmapheresis (also known as apheresis, plasma exchange, or “plex”) is a medical procedure where a device separates whole blood into the cellular components and plasma. The plasma is then discarded and replaced with a colloid fluid, combined back with the cellular components, and returned to the same patient.
What is plasmapheresis?
A: Plasmapheresis is a specialized medical procedure, typically performed in a dedicated plasmapheresis unit. It requires large-bore intravenous catheters to provide sufficient rate of blood flow through the machine. At our institution, Quinton catheters are typically used and have provided reliable intravenous access and excellent safety. Large-bore catheters are typically placed by Interventional Radiology. Outpatient treatment is possible, although most patients who need plasmapheresis for CNS demyelination are hospitalized because of the complications of their underlying condition. Because there are few randomized trials of plasmapheresis, insurance coverage of the procedure is sometimes difficult.
How many plasma exchanges are there?
Q: How many exchanges are performed? A: There is no set number of plasma exchanges performed , although typically patients receive between three and seven exchange s, each of which takes 2-4 hours. The number of treatments can be guided by the clinical recovery, or sometimes a preset number of exchanges are performed.
What happens if you have a plasma exchange?
A: Several reactions may occur during plasma exchange, including fainting, dizziness, or nausea, all of which are caused by hypotension. To reduce the risk of hypotension, patients should be encouraged to drink 6-8 glasses of non-caffeinated fluids each day starting three days before the first treatment. Rarely, patients report paresthesias because of a reaction to the blood thinner, which is treated with extra calcium. Fatigue is sometimes reported by patients after plasma exchange, but typically goes away the next day. Other risks include bleeding or an allergic reaction (itching, wheezing, or rash) to the solutions used to replace the plasma or the sterilizing agents used for the tubing. Excessive suppression of the immune system can temporarily occur due to plasma exchange, which can increase the risk of infection. Rarely, the blood may clot in the machine, making return to the patient impossible. Very rarely, deaths have been reported with plasma exchange, usually from infection or the underlying condition for which plasma exchange treatment was used.
What is colloid fluid?
The colloid fluid is typically a combination of human serum albumin and/or fresh frozen plasma. Typically, a large-bore, double-lumen catheter is used to provide a sufficient volume of blood to perform plasmapheresis over several hours.
Is plasmapheresis a second line therapy?
A: Plasmapheresis is used as a second-line therapy (after systemic corticosteroids) in the management of multiple sclerosis (MS) relapses (or “attacks”) and other central nervous system (CNS) demyelinating diseases including acute disseminated encephalomyelitis, idiopathic transverse myelitis, idiopathic optic neuritis, and neuromyelitis optica. Plasmapheresis is occasionally used inpatients who are intolerant of high-dose corticosteroids or who have medical contraindications to high-dose corticosteroids.
Is NMO a rare disease?
A: NMO is a rare (~1% the incidence of typical MS) inflammatory disease manifest as longitudinally extensive transverse myelitis, optic neuritis, and occasionally atypical brain lesions. A highly specific auto-antibody to the aquaporin-4 water ion channel is seen in the majority of patients with NMO continued on next page 2 syndrome. High-dose corticosteroids are the typical first-line treatment for acute attacks of NMO, but corticosteroids are often insufficiently effective in NMO. Given the probable pathogenic role of antiaquaporin-4 antibodies in serum, it is not surprising that plasmapheresis has been reported to be effective in NMO. 3-5 Repeated courses of plasmapheresis have also been reported to be effective in patients who did not respond to oral immunosuppressive therapies alone. 6 Case series report improvement following plasmapheresis in patients with ADEM, too. 7,8
