What is TPE?
Understanding Therapeutic Plasma Exchange (TPE) Therapeutic plasma exchange (TPE) is a treatment that removes plasma from your blood.
What is TPE (therapeutic plasma exchange)?
Therapeutic plasma exchange (TPE) is a treatment that removes plasma from your blood. The removed plasma is then replaced with a substitute. Plasma is the liquid portion of blood. It helps carry blood cells and other substances throughout your body. With certain diseases, plasma can contain an abnormal substance that may trigger symptoms.
Is TPE a cure for diseases?
Used alone, TPE cannot cure these diseases. But it may help slow their progress and relieve symptoms. When used with other treatments, TPE may increase your chances of fighting the disease. TPE uses a special machine to separate blood into its different parts.
How much plasma is removed from the body during TPE?
Each TPE treatment will remove plasma which is approximately 5% of the child's body weight and an equal amount of FFP was used as a replacement, the total amount does not exceed 3000 mL. An extra part of 100 to 150 mL plasma was needed to prime the extracorporeal circuit to prevent insufficient cycle capacity when the child weighs >10 kg.
What is TPE medicine?
Therapeutic plasma exchange (TPE), also known as plasmapheresis, removes and replaces a patient's blood plasma to treat certain diseases.
What diseases are treated with plasmapheresis?
Plasmapheresis can be used to treat a variety of autoimmune disorders including:myasthenia gravis.Guillain-Barre syndrome.chronic inflammatory demyelinating polyneuropathy.Lambert-Eaton myasthenic syndrome.
What is TPE nursing?
Therapeutic plasma exchange (TPE) is a treatment that removes plasma from your blood. The removed plasma is then replaced with a substitute. Plasma is the liquid portion of blood. It helps carry blood cells and other substances throughout your body.
What is TPE for myasthenia gravis?
Background: Patients with Myasthenia Gravis (MG) can be treated acutely with therapeutic plasma exchange (TPE) or intravenous immune globulin (IVIG). To date, there is no definitive understanding of which of the two treatments is more effective and safer.
Why does a patient need plasmapheresis?
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 ...
Is plasmapheresis the same as 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.
What are side effects of plasma exchange?
The most common reactions were fever, chills, urticaria, muscle cramps, or paresthesias; these reactions were encountered more frequently when plasma was used in the replacement fluid.
How long does plasma exchange last?
A plasma exchange takes about two to three hours, depending on the amount of plasma that needs to be removed.
Does plasma exchange help neuropathy?
During plasma exchange, plasma is removed from the blood and replaced by a plasma substitute. This can reduce the amount of abnormal protein in the blood. However, it does not stop the protein being produced. Other treatments, such as chemotherapy, are needed to reduce the production of the protein by the plasma cells.
What triggers myasthenia gravis?
Myasthenia gravis is caused by a problem with the signals sent between the nerves and the muscles. It's an autoimmune condition, which means it's the result of the immune system (the body's natural defence against infection) mistakenly attacking a healthy part of the body.
Can you build muscle with myasthenia gravis?
These findings indicate that MG patients can indeed improve their functional muscle status as a result of aerobic and high-resistance strength training. This knowledge is important in order to establish collective as well as personalized guidelines on physical exercise for MG patients.
What medications should I avoid with myasthenia gravis?
Drugs to avoid Commonly-used medications like ciprofloxacin or certain other antibiotics, beta-blockers like propranolol, calcium channel blockers, Botox, muscle relaxants, lithium, magnesium, verapamil and more, can worsen the symptoms of myasthenia gravis.
What is TPE in medical terms?
Cost. Therapeutic plasma exchange (TPE), also known as plasmapheresis and apheresis, is a procedure in which the plasma in your blood is removed and replaced with another fluid, similar to what happens in kidney dialysis. It's sometimes used as a therapy in several types of neurological diseases, including multiple sclerosis (MS).
What is the goal of TPE?
1 . The goal of TPE is to remove harmful substances that are circulating in your plasma.
How much does TPE cost?
Prices vary for TPE depending on where you live, where you have it done, and whether or not your insurance covers the procedure, but are somewhere in the ballpark of $1200 per procedure when albumin is the replacement fluid that's used. 20
What blood thinners are used for clots?
Blood clots are another rare serious complication, so your doctor may prescribe a blood thinner called an anticoagulant before your procedure to reduce this risk. 16 Examples include Coumadin (warfarin), Pradaxa (dabigatran), Xarelto (rivaroxaban), Eliquis (apixaban), and Savaysa (edoxaban).
Is TPE good for MS?
TPE is generally a safe and well-tolerated procedure, so it may be a good approach if you're having a re lapse that's not responding to corticosteroids. More research needs to be done on the effects of TPE on progressive MS and as a long-term treatment for MS. Be sure to talk to your doctor about any concerns or questions you may have regarding all of your treatment options and whether TPE might be an appropriate choice for you. You can use our Doctor Discussion Guide below to help you start that conversation.
Where is the blood drawn during TPE?
Blood is then drawn out of your body through the needle in one arm, where it goes through a tube into a blood cell separator, a centrifuge that isolates the plasma from the red and white blood cells.
Can corticosteroids be used for TPE?
The researchers concluded that corticosteroids might still be the first-line therapy in subsequent relapses after TPE. Another 2016 study looked at TPE for 36 patients with either secondary progressive or active primary progressive MS that hadn't responded well or at all to steroid treatment for relapse.
Effective Blood Plasma Removal and Treatment
Therapeutic plasma exchange (TPE), also known as plasmapheresis, removes and replaces a patient's blood plasma to treat certain diseases.
Conditions We Treat with Therapeutic Plasma Exchange
TPE is used in the treatment of various autoimmune diseases, conditions that cause the body to recognize a part of itself as foreign and generate proteins (called autoantibodies) that attack part of the body. These proteins are found in the plasma component of blood.
Therapeutic Plasma Exchange: What to Expect
During this therapy, small amounts of blood are gradually removed through an inserted needle or central line catheter and circulated through a machine that separates blood into red cells, white cells, platelets, and plasma.

What is TPE in blood?
TPE removes large-molecular-weight substances such as harmful antibodies from the plasma. It is usually carried out using an automated blood cell separator to ensure fluid balance and maintain a normal plasma volume. This may require the insertion of a femoral or jugular line to allow adequate blood flow.
How much of an intravascular constituent is removed by a plasma volume exchange?
A one plasma volume exchange removes about 66% of an intravascular constituent and a two plasma volume exchange approximately 85%. TPE is normally combined with disease modifying treatment, such as immunosuppressive drugs, for the underlying condition.

Therapeutic Plasma Exchange Part I: Methods, Goals & Guidelines
In this 2-part series, Tena Griffin covers apheresis methods and goals of treatment, as well as TPE selection criteria, planning and factors influencing dose and schedule.
Indications
How It Works
- During TPE, a machine removes your blood and then separates the plasma, the liquid portion of blood, from your red and white blood cells. The plasma is then discarded and replaced with a different type of fluid, usually donor plasma and/or albumin solution, before being returned along with the cells back to your body.1 Scientists believe that remo...
What The Research Says
- The treatment guidelines from the ASFA,10 which include extensive literature reviews, report that five to seven TPE treatments benefit approximately 50 percent of patients with an MS relapse that doesn't respond to steroid treatment. The researchers also found that the earlier patients were treated, ideally within 14 to 20 days of their symptoms first appearing, the better their outc…
During The Procedure
- During TPE, needles are placed in both of your arms, or sometimes into another location, like your neck, if the veins in your arm can't be accessed. Blood is then drawn out of your body through the needle in one arm, where it goes through a tube into a blood cell separator, a centrifuge that isolates the plasma from the red and white blood cells. The cellular components are combined …
Side Effects and Risks
- Side effects and complications14 depend on a number of factors such as your general health, the number of TPE procedures you have, and the type of replacement fluid that's used. Side effects of TPE are more common when donor plasma is used as the replacement fluid. Serious complications from TPE are not very common. The most dramatic of these is anaphylaxis, whic…
Cost
- Prices vary for TPE depending on where you live, where you have it done, and whether or not your insurance covers the procedure, but are somewhere in the ballpark of $1200 per procedure when albumin is the replacement fluid that's used.20 If your healthcare provider deems it necessary for you to have TPE, your insurance will likely cover it, though you may need pre-approval or a letter …
